⭐⭐⭐⭐⭐ Matt from FH was outstanding! He took the time to walk me through everything and was incredibly thorough from start to finish. He explained all of the electrical work in a way that was easy to understand, including the importance of GFCI protection, current electrical codes, and the rules and regulations that help keep a home safe. What I appreciated most was that he never pressured me. Instead, he gave me several repair options, clearly explained the pros and cons of each, and helped me make an informed decision. His professionalism, knowledge, and attention to detail gave me confidence that my home is properly protected. I highly recommend Matt and the team at FH to anyone looking for an honest, knowledgeable, and professional electrician. Excellent service!

I had Matt in today, with Jonathan shadowing him, and they did great work! Every part of the process was explained to me – what was wrong, what that meant, what it was supposed to look like, and how to fix it. They originally came in for the yearly free maintenance check you get with a membership, but they found an issue with our water pressure system. They fixed it within a couple hours, and were out of my house by noon with a full comprehensive list of what they had done, how long it should last, and an easy expectation that if *anything* was wrong later, they would fix it (for free, up to a year later). Both young men were very helpful, friendly, and professional.

Gustavo Hernandez was excellent! Fh furr has always given us excellent service from plumbing to HVAC. The technicians are respectful of my home. They are very knowledgeable. I have been having issues with my sump for a while with three floods to deal with. No one seemed to know what the issue was and my last sump pump failed in less than a year. But today, Mr Hernandez was able to solve the problem and we are forever grateful. We have the home service plan and it has really paid off. They have a lot of availability and are great with communicating on the day of service.

Accolades and Applause for Brian Newton!!! My husband and I were more than pleased with the work and results from Mr. Newton! His overall professionalism, humility, patience and ongoing explanations of each and every step of our project, was more than exemplary! As Mr. Newton was with us for the entire day, he literally took time to not only answer our questions, but also educated us on each and every step. His overall workmanship was outstanding and needless to say, he left nothing unturned as our garage was left exactly in the way it was when Mr. Newton began. Please note that this was our first time in contacting FH Furr, and we were overwhelmed with the immediate appointment given to us and Mr. Newton’s demeanor, most detailed attention to each and every aspect of his work and above all else, the commitment he showed in making sure all areas of workmanship were completed and workable in every way!!! We commend him for EVERYTHING he did for us today! May he continue to succeed each and every day, so that others as we were today, will truly benefit from his service and success!! Our sincere thanks to Mr. Brian Newton! Samuel and Margaret Bozoian

while the tech that came out was very friendly. They charged me 900$ to clear a clog in my condensate line and replace the P trap. during these 2 visits they completely failed to recognize that the condensate line was the cause of the leak in the hallway or that it was leaking at all. i have no issue with high prices but you should expect A+ tier experience and skill. now it’s 100 degrees and there’s water pouring from the ceiling in front of all our doors. definitely will not be using Len again

Rob Minetree was our tech today and did an excellent job. He came in and got right to work. He was very knowledgeable and it was clear he had experience behind him. He had to go and get some parts as he had used what was stocked on his truck but estimated he would only be gone about a half hour and he was back and working within that time period. He kept me informed what needed to be replaced and also gave me an estimate for replacing the toilet. We chose to repair it and it was done and in good working order in about a half hour as well. He was very pleasant and I would highly recommend him. Thank you, Rob, for a job well done. 👍 Jane Esper

Problem solved and replaced with a much better part. A mitigation clean up team was contacted by Len and they will be here in a couple of hours to schedule for water damage repairs. No better one stop shopping. High five to the repairman who talked and walked me through finding the leak and how the repair is done.

Last Saturday, I finally contacted Len the Plumber because my thermostat needed checking. They immediately dispatched a technician, Mr. H. He diligently identified the root of the problem and fixed it. Before leaving, he answered all my questions and explained the options I had for protecting my HVAC system. I’m so glad I can count on this amazing company whenever I need help. They never disappoint.

I had a great experience with Len The Plumber Heating & Air and especially with Mark J. I scheduled an appointment to get a quote for flushing my tankless water heater and replacing several plastic push/pull drain stoppers in my bathrooms and laundry room with metal ones. Mark took the time to thoroughly inspect everything, explain how the systems worked, and answer all of my questions in a way that was easy to understand. What stood out most was that he was both personable and efficient. Often, technicians are one or the other, but Mark was genuinely friendly while also being professional and knowledgeable. When he provided the estimate, he was upfront about the cost and acknowledged that it was a significant, unplanned expense. After I mentioned that I was trying to stay within a budget, he took the initiative to suggest alternatives and practical ways to spread out the work. Thanks to his recommendations, I decided to replace the drain stoppers one bathroom at a time, which made the project much more manageable financially. I really appreciated his honesty, expertise, and willingness to help find solutions rather than simply selling services. Overall, it was an excellent experience, and I would highly recommend Mark J. and Len The Plumber Heating & Air.

10/10 experience. I needed a toilet replaced but didn’t want to deal with the hassle of going on a website and submitting a request for a quote and jumping through a bunch of hoops before talking to someone. I called ToiletKing and was surprised that Chris answered within the first two rings (used to dealing with robots and automated phone services). Chris was extremely helpful and right to the point. On this 5 minute phone call, I received my quote and scheduled my appointment. When Chris came to install the toilet, he was very professional and took less than an hour to remove the old toilet and install the new one. Will definitely be using ToiletKing in the future.

Chris was fantastic. Professional, polite, super efficient, everything was clean afterwards, including hauling away the trash for the new toilet. Can’t recommend him enough if you need a toilet replaced.

Mary Ann Sarnovsky

I can’t say enough good things about the incredible service I received yesterday when Chris and his son came to install a new toilet in my basement bathroom. From inception to completion, just as his ad states, took less than 24 hours. He was professional, polite, prompt and extremely efficient in every way. He even assured me that I did not in fact need a new shut off valve that I’d added to the order, and is going to credit my account for the price of the valve. That’s the kind of honesty and professionalism that seems to be all too rare these days, but I surely did appreciate it! I will absolutely be calling Chris the next time I need a new toilet, and if you’re reading this review, and looking to get a new toilet, I highly suggest you call him as well, as you won’t find better service or value. Thanks again Chris!

Nick did an amazing job. Explained the process, found the problem, explained my options, did the job and referred me to there restoration people as the water damaged actually got under the wood floor in two rooms. The job was fixing a leaky waterline behind the refrigerator. Price was fair, job was done professionally. Will definitely use them again.

We had a great experience with Ruma Plumbing and especially with Wael. They came out the very next day when we were concerned about a possible gas leak from our cooktop and also needed help with a toilet flushing issue. Wael arrived right on time, was professional, thorough, and took the time to clearly explain what he found and what needed to be done. He fixed the toilet issue and gave us peace of mind regarding the gas concern. The cost was also extremely reasonable, which we really appreciated. It’s hard to find service companies that are responsive, honest, and reliable, but Ruma Plumbing delivered on all of it. Highly recommend them to anyone in Northern Virginia!

The Roto-Rooter technician (plumber) came and he was very courteous and knowledgeable. He almost immediately identify the problem and provided his assessment with quote for the repairs. The price was reasonable and we accepted. The plumber fixed the pipe in no time. We are very pleased with the job done. We definitely recommend Roto-Rooter for situation like this a pipe broken or other plumbing jobs. This is the first time we use their services and the plumber worked well. We are very satisfied.

Nick (from RR) was PROFESSIONAL & AWESOME. He constantly communicated everything with us (tenants) & the landlord. He went above & beyond to find the sewer gas leak(s). He did his initial inspection (throughout the entire house) but no visible leak(s) were found, so he did the smoke/fog test at least 6 times or more. Also, he went back up in the attic, but no leak(s) found. So, he removed the toilet caps to see if there was any leak(s). Yes he discovered the leak from the toilet after removing the caps. He replaced the rings for 2 toilets (reported in the work order) & was willing to check the remaining 2 toilets even though they weren’t in the work order. He really cares about his customers & didn’t act like it was just a job. We will request Nick for any plumbing issues & recommend this Roto-Rooter location. Thanks again Nick for your GREAT service & patience.

I called Roto-Rooter for kitchen sink is backed up, but we ultimately chose not to move forward with their services because of their predatory pricing structure and high-pressure warranty sales tactics. The issues started from the very beginning. When I called the receptionist to get a basic estimate or a price range for standard drain snaking, she completely refused to give me any numbers, claiming only a technician could tell me the price. This company has been in business for decades; there is no reason they cannot give a standard baseline range over the phone. However, because they advertised a “Free Estimate,” I booked the appointment anyway. (I had actually canceled a different plumbing company first because they wanted to charge a $69 upfront diagnostic fee just to come out). My husband was home for the appointment, and I had him call me with the pricing. Before he arrived, my husband had already run a 100-foot mechanical snake down the line ourselves, which we openly disclosed. The technician’s baseline price just to run their snake machine was $455—and that didn’t even include a warranty! He then offered a deal where he would run his corporate snake machine, and if it didn’t work, he wouldn’t charge us the $455 for it, but he would hydro-jet the line instead for an astronomical $2,000. It felt like he simply bundled the hidden cost of the snake, a fake discount, and the jetting into one heavily inflated price. On top of that, he aggressively tried to push a 6-month extended warranty for an extra $428, total $893. If the warranty had been for 3 years, I would not have minded paying for that peace of mind. But paying $428 for only 6 months is outrageous. It made me incredibly anxious that if I didn’t buy the extra warranty, the technician wouldn’t do a proper job. To ensure the line was truly clear, I requested that hot tap water be left running for an hour after the work (stating the technician didn’t even need to stay for it). He flatly refused to run it for more than 20 minutes and offered zero professional explanation as to why. When I directly asked him, “If I run the hot water myself after you leave today and it backs up again up immediately, what will you do?” he completely dodged the question. He wouldn’t promise to come back out if it failed that same day. He simply said do we want him to do it or not. We ultimately decided not to do the work with them because we do not want to pay overpriced fees for work that isn’t guaranteed unless you buy a short-term warranty. Roto-Rooter uses “Free Estimates” to get their foot in the door, then hits you with high-pressure sales scripts. We are taking our business to an honest, independent local plumber instead.

I called 6 different businesses in my area for quotes to have my broken and leaking water heater replaced. Clover hands down had the best value AND the best customer service experience! I was blown away! While most companies charge for a quote or require a technician visit, Clover offered me a free, no-hassle quote over the phone by simply sending a few pictures (which they offer for certain services). I initially spoke with Lizzie on the phone who helped me get the process started. She was extremely helpful, understanding, and responsive with my primary call and follow up questions. She also walked me through their many guarantees and signature service benefits. After choosing Clover, they were able to schedule me for next day service to quickly have my water heater replaced. The service technicians (Austin and Ricky) were incredibly professional and walked me through everything they were doing. They are clearly knowledgeable and highly trained in their craft and we’re well equipped to answer any questions I had. I highly recommend Clover and will plan on using their services again if needed!

We received quotes from a lot of HVAC companies and ultimately used Clover. Ryan did an awesome job at helping us figure out the issue with our Furnace – blower motor and inducer was bad. Since the unit was so old (20 years old) we went ahead and replaced that. We noticed major corrosion on our water heater and I asked them about fixing the dryer exhaust pipes in the wall because somehow that was crushed. Long story short we replaced the furnace, water heater and they fixed the damaged dryer exhaust pipe in the wall. They even replaced/fixed all the old gas and water pipes hooking up to the furnace/water heater. They did an awesome job. We added on some extras like the Honeywell air filtration system and the extra home air purifier with a humidifier for the home. This has helped tremendously with allergies, and dry nose during the winter. I only have the “after photos” but compared to before it looks 100% better, our furnace works great now. The piping system is still complicated but they made it way better than before. Also want to say thanks for the muffins.

Clover Services was one of very few responses I received (and were extremely quick) to respond to my request for an estimate to repair (but most likely replace) my elderly father’s old boiler system from the 1970’s. They arranged for one of their best technicians to evaluate the system as soon as possible and he spent a lot of time analyzing how best to replace and dispose of the the old system. Their prices were competitive and the total amount was exactly what we expected it would cost to replace. The company went above and beyond to get the equipment ordered and installed as quickly as possible so my father would have heat in time for the cold weather. This was not an easy job and not one that many companies wanted to attempt – but Clover Services, Ryan and all of their technicians took this job without hesitation and worked hard for two days to get it done. Ryan, the lead tech, was extremely professional, communicative and friendly (as was Wendy in the office) and they both made sure I understood the estimate, the timeline and all that the job entailed. They also treated my father and his home with dignity and respect. They did a fantastic job and I wouldn’t hesitate to hire them again!

I hired Clover Contracting for some plumbing work at my home, and overall, I had a very positive experience. The plumber arrived on time, quickly identified the issue, and explained the repair process in simple terms. They fixed a leaky pipe and also checked the water heater to ensure everything was running smoothly. The service was professional, and the pricing felt fair for the quality of work. The only reason I didn’t give a full 5 stars is because the cleanup could have been a bit more thorough, but I’d definitely call them again.

On Jan 16th I called CLOVER HVAC service because my HVAC was shutting down and home wasn’t heating. They sent two technicians to home in short time. They observed the code 31 or 13 flashing on the carrier HVAC and told me it’s the pressure switch that is faulty. Since they claimed they were licensed and experienced technician I trusted them and paid $478 in total ( $99 for the visit + $379 advance payment o replace the pressure switch for next visit ). After they left, the HVAC system was working, blowing hot air but doesn’t take break when indoor temperature reaches thermostat set temperature. (This is quite dangerous for multitude of reasons). It was like furnace inside the home. I called them to visit home and check. They suggested, I should attempt to fix while they instruct me how to do it on phone. WHAT A WORST IDEA. JUST to keep my property safe I attempted it with lot of hesitation and fear of the furnace. Then I see the furnace started accumulating water quite close to the electric/mother circuit board. I was scared because its basic electrical 101, water with active current is a worst scene. They came back on the same evening and fixed it. I was really unsatisfied & frustrated and called their office and ASKED THEM “PLEASE CANCEL MY NEXT SERVICE OF REPLACING THE PRESSURE SWITCH” because of their inexperience and the mess. They told me that they will refund that day visit cost $99 and will send a senior technician to do “FULL SYSTEM DIAGNOSTIC CHECK AND IF AT ALL NECESSARY, THEY WILL REPLACE THE SWITCH”. I didn’t like the idea but I finally agreed after they repeatedly declining to cancel the next appointment with them. Then the senior tech came and couldn’t really pinned down the issue and replaces the pressure switch without concrete evidence. The HVAC ran fine for 4 days and on fifth day it started flashing the same error code 31 or 13 . I called them and they sent same senior tech again as soon as they could. At this visit he claimed he did what he should have done in his earlier visits . i.e HVAC 101. ANY LICENSING SCHOOL WOULD TEACH THIS, WHENEVER HVAC FLASHING PRESSURE SWITCH CODE YOU SHOULD 1) OPEN THE BLOWER FAN, CHECK FOR ANY CLOGS, DEBRIS AND CONDENSATE LIQUID? THEY DIDN’T DO THIS. NOT EVEN TOUCHED IT. 2) CHECK EXHAUST, INTAKE AND DRAIN PIPES TO CHECK FOR ANY CLOGS. THEY DID EXAMINE THIS. 3) CHECK THE ELECTRICAL COMPONENTS FOR ANY ISSUE. THEY TESTED THIS. WHY DIDN’T YOU CHECK THE BLOWER FAN?? WAS IT TOO SIMPLE AND DOESN’T COST MUCH TO CUSTOMER? The HVAC stopped working again for the second time and this time knew I will be a total fool if I call them because $379 + three CLOVER technicians + four visits couldn’t fix it . Either they knew what was the problem and they choose not to operate and scam me by replacing a well-functioning part or they don’t know above point (1). By looking at the below attached pictures and not doing HVAC 101 point (1), you might be convinced the first case is likely true. i.e they wanted to do something which would bring more money and not doing simple cleaning which could have done during their first visit for just $99. After waiting for two cold nights a genuine technician came and said there is nothing wrong with old pressure switch (he tested it by replacing it) or another component. AND just the ducts and pipes needed further cleaning. IT has been a couple days it’s working. I called them for a refund since they claim “MONEY BACK GUARANTEE” if their service was unsatisfactory. SINCE YOU COULD FIX THE PROBLEM AND DIDN’T DO THE BASIC CHECK IN YOUR FIRST VISIT YOU SHULD REFUND. They tell me, they already gave $99 discount and cannot offer any further discount. I WANT TO REMIND; YOU GAVE ME $99 BECAUSE YOU PUT MY WHOLE HVAC AT RISK BECAUSE OF THE WATER LEAKING FROM THE EXHAUST PIEPE. IT WAS YOUR FAULT. YOU DIDN’T DO A FAVOUR TO ME. Now I am asking for refund because even after four visits and charging me $379 you couldn’t fix the issue AND REPLACED A WELL FUNCTIONING PART WHICH WAS TOTAL UNNECESSARY. You break my confidence and trust.

While no homeowner ever puts a water damage remediation project on their wish list of home improvement projects, from start to finish the whole team at United Water Restoration Group of Sterling were great to work with. They understand that these types of projects can create a tremendous amount of stress on homeowners and their families, and they went out of their way to demonstrate their competence and provide great service. We had water overflow from or main level bathroom down to our lower level bathroom/foyer right before the weekend. They had someone come out right away to assess the damages and also had a point of contact to talk to us over the weekend to provide information of the process and answer any questions we had which really helped us make the best of our situation. Their workers were professionals and courteous and was able to provide answers for us on the spot. We highly recommend them!

We reached out to United Water Restoration Group after discovering a leak in our basement, and found that our kitchen sink above had worn and caused a large amount of damage to multiple rooms in the house, and despite the awful situation our experience working with them has been absolutely wonderful. In the beginning we explained up front that we were a little nervous about this process, as we recently experienced a death in the family causing some financial issues and had an awful experience with our last contractor abandoning the project and producing very poor quality work. They assured us they were going to take care of everything, communicated frequently and clearly about what needed to be done, gave us a timeline for the work which they were able to successfully stick to, and all of the work itself was fantastic, and the people we interacted with were extremely friendly. Justin and Dumitru were wonderful especially, and did such a great job with the work that I can’t say enough how happy we are after having such an awful experience with a different company previously. I would absolutely suggest United Water Restoration Group if you want to work with a reliable company that is both professional and friendly. Thank you all again for the hard work when we needed it!

Melvin, Mickey, and team were absolutely amazing. We had water leaking from our master shower down through the ceiling into our kitchen. They arrived immediately and assessed the situation and with our approval, started the mitigation process that day. They also took us through every step of the process including coordinating with our insurance company and plumbers. They are the best!!! Highly recommend !!

I was devastated after finding out that my basement had completely flooded in a house that I had just bought — and on Christmas Day no less. Once I found United Water Restoration Group, I was so relieved to have a team who would handle the drying, mold remediation, AND the rebuild. They were professional, responsive, and gave me a great deal. My basement is now completely finished (new flooring, walls, cabinets, & fresh paint job) and looks incredible. I would highly recommend them.

I recently had Dulles Plumbing out to repair my HVAC system and replace my water heater, and I couldn’t be more impressed. From the initial diagnostic to the final install, the team was incredibly professional. They took the time to explain the technical issues with my AC and offered a fair, transparent quote for the new water heater. The installation was clean, they respected my home, and both systems are now running perfectly. It’s rare to find a company that handles both mechanical and plumbing with this level of expertise. Highly recommend!

Recently had to replace my HVAC unit for my home. This is the 2nd time I used Dulles Plumbing, Heating, and Air for a major HVAC overall as I have multiple units. I highly recommend the Dulles team….great communication, timely and professional install, and follow-up experience. Appreciate all the team did to make this happen.

Our water heater stopped working and we ordered a new one from Modern Mechanical. Technician plumber Brett Knox arrived at out home at 9:30 this morning as promised in a text sent 45 minutes earlier. He scoped things out and went to work. He wrestled the old bulky 75 gallon tank out of the utility closet and installed a new 50 gallon tank in about 3.5 hours. He did a beautiful job with the copper piping and put in a new expansion tank. He also realigned the overflow pipe from the new overflow pan so it didn’t conflict with the access to our HVAC filter as before. Brett was extremely courteous, professional and trustworthy. Brett is a thoughtful, kind individual with a positive vibe about him. We enjoyed having him in our home. I would highly recommend Brett for any of your plumbing needs.

Very happy with the new HVAC installation. Their quote was much less than a competitor and for a better product and warranty. Rafael and Chris did an amazing job digging out the snow to get everything set up correctly. Highly recommend them

We recently had our HVAC replaced by Modern Mechanical and George was the most honest salesperson I’ve ever met. He was upfront with the costs, pros/cons of various units and took the time to walk us through the entire process to make an informed decision. The installers were great and didn’t leave a mess behind and took the time to show us some of the features of the furnace, humidifier, AC and thermostat.

We ended up needing a new hot water heater unexpectedly. Omar, with Modern Mechanical, showed up within the scheduled time frame and went right to work . He diagnosed the situation to determine if he could salvage the existing hot water heater with a repair or if replacing it was the best option. The 20 year old unit needed replacing so Omar began the job. He worked non stop until the new water heater was installed and functioning properly. His work is very clean, neat and professional. Would / will definitely recommend him and Modern Mechanical to others.

I have used Modern Mechanical for the past 3 years and have been repeatedly disappointed by their shoddy workmanship and poor customer service. Modern Mechanical installed a new heat pump and condenser at my home 3 years ago. A week later, I needed a breaker replacement due to the new system overloading the breaker. Despite having signed up for the Home Guard membership and having a one-year warranty in place, I did not receive the advertised discount or any other adjustment. Last year, I required a repair for a refrigerant leak. I again did not receive the Home Guard discount. Moreover, the technician explained that the leak was due to improper installation of the condenser by Modern Mechanical two years earlier. The technician was incredibly rude, chatting with a friend he brought along, and the company took no corrective action to fix the improper installation after his visit. I had yet another leak this year, from the heat pump this time. The technician didn’t address the leak, but he reiterated that our condenser was improperly installed by Modern Mechanical. When I called the company to explain the situation, I was told that management would respond shortly. I received a call back moments later from the customer service agent I had spoken to, only to be yelled at and berated for bringing up an issue which the company’s own technicians had repeatedly raised. I later received an email from management which refused to address the technicians’ concerns about the improper installation, as well as the overcharged service visits. If you are looking for peace of mind and an HVAC system that works, do not choose Modern Mechanical.

    Frequently asked questions about plumbers in Ashburn

    How do I choose a good plumber?

    Choosing a good plumber involves looking for specific qualities and asking the right questions. You should seek plumbers who are licensed and insured, possess relevant experience for the job you need done, and can provide clear estimates and references. It's also beneficial to find plumbers who communicate clearly, are punctual, and offer fair pricing for their services.

    What is the difference between plumbers' putty and caulk?

    Plumbers' putty and caulk serve similar sealing purposes but have distinct applications and properties. Plumbers' putty is a pliable, non-hardening compound primarily used to create a watertight seal around fixtures like drains and faucets, and it's ideal for surfaces that might be disassembled later. Caulk, on the other hand, is a flexible sealant that hardens over time, commonly used for filling gaps around tubs, sinks, and backsplashes, providing a more permanent and often aesthetically pleasing finish.
