I just made my umpteenth referral for Collins. At this point I should probably get a referral fee. 😉 For the record, I don't. Many times when people come to my home and see my garage, they ask me who did the work. It's been FIVE YEARS now and I'm still very happy with the work that Collins did. Admittedly, I keep the floor clean by pressure washing it frequently and treat it well but after yet another referral to Collins just a few minutes ago I realized that they weren't getting the review from me that they deserved. DO NOT HESITATE. You might find cheaper pricing but the prep work is key to a long lasting floor. Buck and his crew do quality work.

I live out of state and bought a new home in Virginia. Before I moved in, I wanted the driveway floor done. Collins Concrete immediately answered the phone and sent me numerous pictures of different projects. I had no problem getting the garage floor taken care of before I even saw my new home. Collins Concrete handles everything from start to finish and is more than helpful. I would recommend them to anyone. So nice to have a personal touch.

I couldn’t be happier with the work done by Collins Concrete Coatings. From start to finish, the entire experience was professional, organized, and customer-focused. They did an outstanding job installing my garage floor coating and the Proslat wall storage system, completely transforming my garage into a clean, functional, and impressive space. A special thank you to Buck, Heidi, Dana, and the installation team for their excellent communication, attention to detail, and craftsmanship throughout the project. The quality of the finished product exceeded my expectations, and it’s clear they take great pride in their work. If you’re looking to upgrade your garage, I highly recommend Collins Concrete Coatings.

Outstanding! Working with Collins Concrete has been so professional. From step one until job completion the process has been flawless. Install team was on time, professional and very tidy. Once complete you could not tell they were there except for the beautiful garage floor and stairs they left. Highly recommend.

We are absolutely delighted with the garage floor project that Collins just completed for us. They were outstanding from the first visit to estimate the job, to the detailed explanation of the materials/process, to the scheduling, and final product. Every step and every interaction with the company was highly professional, courteous, and inspired confidence. I would recommend Collins to anyone who has dreamed about a commercial-grade, beautiful floor for their business or home.

We had such a wonderful experience with Galaxy for our countertop fabrication. From start to finish, David truly went above and beyond to make sure we were completely happy with the final result. He was incredibly kind, patient, and considerate throughout the entire process, taking the time to answer questions and ensure every detail was just right. The craftsmanship is outstanding — the countertops turned out absolutely beautiful and exceeded our expectations. You can tell he genuinely cares about his work and his clients. We couldn’t have asked for a better experience and highly recommend him to anyone looking for quality workmanship and exceptional service.

David and his team stood out to me for their attention to detail. He brings a wealth of knowledge and advice on what works and what looks nice. I constantly noted how David found little issues to fix, or small details to adjust before we did, and was constantly visiting to check on the progress and converse with his team. The result was a beautiful bathroom rebuild and remodel we're thrilled with. I can't recommend him enough.

Exceptional Service and Quality! I recently had the pleasure of working with Galaxy Construction & Remodeling for my home renovation project, and I was delighted with their work. The team was very professional and attentive to my needs. The crew was punctual, respectful, and worked efficiently, always keeping the work area clean and organized. My home looks absolutely stunning, and I couldn’t be more happier with how everything turned out. I recommend Galaxy Construction & Remodeling to anyone looking for top-notch construction and remodeling services. They truly go above and beyond to deliver exceptional results!

⭐⭐⭐⭐⭐ I recently had my kitchen remodeled by Galaxy Construction and Remodeling, and I couldn't be happier with the results! From the initial consultation to the final touches, their team was professional, knowledgeable, and attentive to my needs. They helped me choose the perfect cabinets and countertops that fit my style and budget. The craftsmanship is top-notch, and the installation was seamless. I appreciated how they kept the workspace clean and respected my home throughout the project. Communication was excellent; they kept me updated on the timeline and any changes. I highly recommend Galaxy construction and remodeling for anyone looking to upgrade their kitchen. They truly transformed my space into a Dream kitchen.

BUYER BEWARE — Galaxy Construction also does business as Galaxy Restoration. This review reflects my personal experience and opinions. I initially dealt directly with Galaxy's owner/president following damage to my home and relied in good faith on his representations and expertise. He directed me to a separate mitigation company doing business as Flood Doctor/Restoration Doctor. Based on my interactions with Galaxy, I understood that company to be functioning as Galaxy's mitigation subcontractor. I later learned that I had actually entered a separate contract directly with the mitigation company. That distinction became important when the mitigation billing became disputed. The first mitigation invoice was $11,773.16, later increased to $13,643.16, and was subsequently corrected to $12,363.36 after billing issues were challenged. My insurance company valued the mitigation substantially lower. For complete accuracy, that dispute was ultimately resolved through credits and adjustments, resulting in an agreed final payment of $8,143.16 to the mitigation company with a zero balance. My concern with Galaxy is the gray zone surrounding its role in this arrangement. Galaxy's involvement went beyond simply providing a referral. Its owner performed supervisory functions associated with the project, and Galaxy required me to pay it a $2,500 deposit. That deposit was subsequently credited dollar-for-dollar toward the separate mitigation company's invoice. I am not alleging that this transfer was improper; the credit ultimately reduced what I owed. My concern is transparency. As a consumer, I believe I should have clearly understood from the beginning that I was dealing with separate companies and separate contractual relationships, what role Galaxy would continue to perform, and how money paid to Galaxy could ultimately be applied to another company's account. That is the gray zone I wish I had understood beforehand: rely on one restoration contractor → get directed to another company you understand to be its subcontractor → discover you actually contracted independently with that company → original contractor remains involved in the project and accepts your deposit → deposit is ultimately applied to the other company's invoice. Consumers should not rely on informal understandings about who is working for whom. Before doing business with Galaxy Construction/Galaxy Restoration, get the relationships in writing. Ask whether any recommended mitigation company is actually Galaxy's subcontractor or an independent contractor. Understand exactly what Galaxy is supervising, which company you are contracting with, who will bill you, and where any deposit you pay can ultimately be applied. Have your insurance company review the contracts before work begins. My criticism is about transparency and the process I experienced—not an allegation that the $2,500 credit itself was improper.

Daniel and all his crews were extremely professional at all times. We were always kept appraised of the status of the job. In addition, Daniel was very accommodating when we added several additional (small) items that we wanted done as well as a "custom" area with ventilation & lights under the stairs for our cats. We very happy with the final product. Would definitely recommend Loudoun Basements to anyone looking for a great job done at a reasonable price.

Loudoun Basements did an excellent job from the beginning to the end of the project. They had quick responses to quote requests, revisions (responses to new requirements), and close out. Project managers did a great job keeping open communication and ensuring they were delivering to expectation on this custom basement bar project. Workmanship, attention to detail and staff professionalism were of consistent high quality. The worksite was kept organized and clear during the project as well as cleaning up end of project.

We couldn’t be happier with the work from Daniel and his team! We sought out multiple quotes before getting started, and knew right away after meeting Daniel that his company was the right one for the job. He helped us play with multiple configurations to find the optimal space for our basement, was patient when we made changes prior to building, and the team worked professionally, and with patience to ensure it was all completed to our satisfaction. Would highly recommend to anyone looking for the right team to take on a basement project!

We contracted Daniel with Loudoun Basements to help us install drywall, painting and tile in our basement remodel project. The team was very competitive on price, was always on time, and Daniel has been the best contractor I have worked with in years. He was always communicating with us, open to ideas and many questions about the process and timeline, and flexible on some minor changes we had throughout the installation. His drywall installers ensured we had clean walls and sanded perfectly to ensure paint did not show imperfections. The painting was absolutely on point as well – with precision cut-ins and multiple coats to ensure full coating of drywall. And his team also install flooring – a quality product provided by Mosaic Tile of Chantilly (They also provided the designer for the tile work in the bathroom and supplies). And we could not be happier with the shower – it absolutely fits the vision of what we wanted to accomplish. Overall, about 1200sf added to our home and it has a great, cozy feel. Great job, Daniel and the Loudoun Basements team!

I would highly recommend Daniel and his team at Loudoun Basements for any and all of your renovation and/or remodeling plans. My wife and I are both in real estate and know several contractors who could have completed the job, however, when we discussed our plans with the Daniel, we were confident that the right choice was made. He provided a great value and an incredible finished product. Our basement was completely unfinished, and he followed the architectural plan precisely to end with a fully finished area with two additional bedrooms, fitness room, wet bar, storage area, hardwood (LVP) flooring, full bathroom. We could not be happier with the finished product. Coming from a real estate background and seeing plenty of spaces, I can say the finished product that Loudoun Basements delivers is one of the best….quality and value!

Mario and his team were amazing – he did a patio for me and they addressed the drainage system free of cost. We ended up planting shrubs and trees based on his recommendation! Highly recommend them.

They are very affordable. They did a nice stone work around the planters, with landscape lighting that’s enhances the overall look of the patio. We are very happy with the end product. JC

We had Homeland install rows of trees to create a privacy border for our yard. They designed a combination of evergreen and flowering trees to create privacy and visual interest. The trees were incredibly healthy and weathered the tough winter. The blooms this spring were a welcome delight. Mario and his crew were a joy to work with. They were professional, arrived on time and cleaned up the site afterwards. We are having them back for additional work this year.

Mario and his team did an excellent job in helping us design and completely revamp our backyard, driveway, and front walkway/stoop. The work area was kept clean during the construction process and the works were very courteous. This project was extensive and took 5 months to complete. I highly recommend Mario and his team.

Cannot say enough good things about Mario, his crew, and Homeland as a whole. The quality of work, attention to detail, and level of professionalism was second to none. So much so that after seeing it firsthand, 3 other neighbors decided to do projects with homeland. Mario was very accommodating and even thru changes mid-project he was always focused on our happiness with the finished product. He told me "I don’t care if I have to come back 100 times to go over the plan, I just want to make sure it’s what you want in the end." Which sounds great in theory, but I tested that more than a few times, and he actually meant it. It’s nice to find someone who gives you that personal touch and makes you feel like it’s about you, and not just another job. Couldn’t be happier with the results and the whole experience as a whole. We found our contractor for life

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!

Both technicians (Carlos & Alberto) were very courteous & professional. Alberto spent time explaining things to me throughout the day. Before they left for the day, they made sure cords were taped down & did an excellent job of cleaning up for the day. I would highly recommend your company.

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.

After interviewing a few other contractors, we decided to go with Kamran for a carpet stretch job. I was impressed with his knowledge, experience and upfront personality. He took the time to explain the root of the carpet buckling issue we had and also how he recommended going about how to fix it properly. His lifetime guarantee was also a plus. I would use him again in the future and strongly recommend him for any carpet repair you may need.

Kamran did a wonderful job explaining the issue with the wrinkles in our carpet. He explained how he was going to fix it and why they occurred in the first place. He did a great job smoothing them all out and stretching the carpet as it should have been installed. We are so happy with the fix and people won't trip on the carpet anymore. Great job and we would not hesitate to use him again for fixes, and he guarantees his work. Thanks Kamran!

Kamran did an outstanding job in repairing and stretching our carpet. It now looks perfect! He is also very professional and even vacuumed any carpet remnants when he finished working. We highly recommend him to anyone who needs carpet stretching and/or repairs! Eileen and Morgan Bramlet

I decided to give this company a try for a carpet repair job after looking over reviews and speaking with the owner. He offered to come for a free estimate. The estimate was easy to schedule at a convenient time. He arrived promptly and provided a very reasonable estimate. He then did the work on the spot. The quality was exceptional. The price was very reasonable. I highly recommend Flood Depot DMV without reservation. I think that anyone who uses them will be extremely pleased in all respects.

Used Karan for 4 carpets. I called him with an urgent request and he promised me he would make it—and he did, despite it being a long day for him. His work quality was fantastic! I’m so happy I found him online. I would definitely recommend!!!

I had a great experience with Prime Solution. Their team painted my house and the results were excellent. They worked professionally, kept everything clean, and paid close attention to details. The communication throughout the project was clear and smooth. I highly recommend Prime Solution to anyone looking for reliable and high-quality painting or home improvement services.

Prime Solutions LLC did an excellent job restoring my home after water damage. Their team was professional, responsive, and efficient from start to finish. They explained the process clearly and made a stressful situation much easier. The quality of their work was outstanding, and I highly recommend them to anyone in need of restoration services.

I am a licensed architect and have used MDB numerous times over the past 15 years on my two different homes in the Leesburg Va. area. Most recently, this past summer [2023], I used them on my son's home. Melvin is absolutely a great leader, communicator, and provides thoroughly detailed estimates. The scope is fully understood before proceeding and they are great at communicating work schedules. His teams are extremely skilled, talented, and professional. Their work is always of the highest quality. I could not be more pleased with their performance. Highly recommend them for any painting and residential construction or repair.

I have never written a review before but I have to write one regarding MDB Painting. We have been using their services for at least 12 years now and they never, ever disappoint. Mel is always so gracious and his workers are top notch. Work is always done quickly and in a professional manner. I would highly recommend MDB for any household issue, not, just for painting. They are always willing to take on any task, big or small!!

We have been working with MDB for the past 15 years for interior and exterior projects. MDB has painted our exterior multiple times, built our fence from scratch, power washed and stained our deck, renovated 3 bathrooms and added on a bedroom. They are our trusted go to contractor. Their prices are fair and the follow up for any minor issue has been very timely. The owner Melvin and his team have always been professional and easy to work with.

I had MDB paint pretty much every room of my house while we were still living in it. They were very considerate the entire time. It was our first experience with MDB and are very pleased with the results. They kindly came over and painted samples of the colors we were considering before they started. They did a great job with repairs and paint; it looks and feels like a new house!

I have been using MDB for 10 years. Always a excellent experience. They go beyond to please you and truly a professional company.

Horrible workmanship!! This company installed the original roof on my house. Within one and a half years of the install, there were multiple leaks. This company doesn't appear to be interested in standing behind their workmanship.

I requested an estimate and they came right out. They quoted me the price and once I agreed they quickly scheduled my work. I was getting a full roof replacement as the roof hasn't been replaced in over 20 years. During scheduling they walked me through the process. they told me which day the materials would be delivered and which day the work would start which was the next day. The crew showed up and laid tarps around the entire home. I had some rotten wood on the roof and the price to fix that was extremely reasonable and they had what they needed on hand so there was no delay. Once done they left the area cleaner than when they arrived blowing off all the side walks and porches which I had not gotten two. I would definitely recommend Darvish to family and friends.

From the first contact with company from proposal to final installation I was treated in a professional manner and they were always responsive to my concerns. If a date slipped due to the weather I was immediately informed. The work crew was there on time, kept the work area cleaned and did a great overall job. The finished roof was exceptional, I have gotten numerous comments from neighbors and passer byers, 3 have asked for the companies phone number. I was especially pleased by the prompt follow up company inspector who reviewed the final job immediately after it was finished. Overall I am extremely pleased with my experience with Darvish Construction and I would highly recommend them to my neighbors and friends.

At our previous home, we had a leak that kept persisting after multiple repairs from another roofing company. Even though we were under warranty, we got so frustrated that we decided to hire John Darvish Construction and the problem was resolved. We never had a problem with the leak for the next 15 years. Recently we bought a fixer up in DC and hired John Darvish Construction Co. It was the best experience ever. The job was completed on time, actually earlier than promised. The crew was professional, competent and left the job spotless. Without any hesitation, we highly recommend John Darvish Construction Co.

This is a second time that I have replaced my roof in two properties. I was initially pleased with pricing and their responsiveness. The crew came with impressive equipment and started working quickly due to weather uncertainties. I have a very large house and roof but they managed to do an excellent job within a few days, shorter than expected. They followed it up with another inspection within a few weeks to make sure everything was OK. The quality of workmanship is excellent and several of my neighbors complimented me. I will not hesitate to use them again.

Select Construction came to our house two days after we called about several missing shingles and bare plywood on our 8-year-old roof, which a neighbor had alerted us to. Technician Julio was extremely friendly, informative and thorough. He was ready to repair our roof the same day, which was great because it was supposed to rain heavily the next day. He reported no damaged plywood, laid new roofing paper, and replaced over 20 shingles, taking the extra step to apply roofing cement to each shingle (on top of the self-adhesive already on the shingles). Select would charge $280 for minimum roof repair of replacing up to five shingles, $360 for replacing about 10 shingles, and they charged us $480 to replace over 20 shingles. Based on the experiences of other neighbors, we were lucky to find a roofer that was willing to do small repairs, and we were lucky to be charged such a reasonable price. We highly recommend them! June 19, 2025 follow-up: I contacted Select to replace a couple more missing shingles. Louisa informed me that their price for minor repairs had gone up, but they gave me the original price since there were only two shingles and I had been a repeat customer. I greatly appreciate this level of customer service and recognition!

Do not contract with Select Construction. You will have to "SELECT" which one of your bank accounts you want to pull money from for repair because they DO NOT honor any warranty on their work. I have the same problem as other customers with our metal roof installation. They leak water. Consider yourself lucky if you catch it before it destroys your home. The poor installation was done very quickly and they did not seal under or around the roofline before they slapped the roof on my home. BEWARE!! They do not have or honor any warranty on their poor craftsmanship!!

Installed roofing on new toll home in 2012. Metal porch roof done incorrectly with layers of caulk underneath. Addressed problem with roofer and builder. Supposedly fixed. Eight years later leaking a great deal. Contractor I hired took photos and said roof had been leaking all along and was done improperly. Select Roofing refuses to do anything, saying it is not under warranty. They created the problem but don’t want to own it. Toll is just as guilty for using this contractor and allowing substandard work. Avoid this company like the plague.

Select put the original roof on a newly constructed home I bought in two rivers , Odenton. The house was 5 years old when the roof stated leaking. Inspection of the roof noted quality shingles installed by someone with no knowledge of how to use a nail gun (nails were left only partially nailed in & no none came behind with a hammer to tap in the nails in that did not go all the way down.) Some singles were sliced all the way thru, it was explained that this would happen when wrapped bails of shingles were opened with a utility knife , no care must have been taken to only slice thru the plastic. I still would not have seen a leak if proper overlapping of shingles had taken place. One of the men, when inspecting the roof got a nail in his boot, a nail had been left ‘standing up’ and a shingle slapped down on top of it. It’s disgusting that this Co. has no integrity to stand behind the work that was done so poorly. The warranty offer by the builder for the roof (Classic homes of Maryland) is one year. Unbelievable, when the shingles that were used are rated to withstand 120 miles hr winds and last 30 years, are now no good because of such poor installation Pitiful , that the workmanship was so bad, that I am now replacing a roof on a home a little over 5 years old.

Julio was great! I'm a homeowner that had a disagreement with our builder, Toll Brothers, about what was causing peeling paint on a bathroom ceiling. Julio went into our attic, carefully walked the trusses to reach the spot where the bathroom vent came out of the ceiling. Toll Brothers' inspectors were unwilling to do that. Julio took pictures to show that there was no leak and the ceiling drywall was unstained. Then Julio went onto the roof and sealed each vent by lifting up the shingles around the vent. He said builders have not been doing this until 2 years ago or so. Our house was built 6 years ago so we were glad to have this done. He said nothing had seeped through, but now we're more protected. He also caulked around the pipe boot of each vent. He also checked the dryer vent and pulled a softball-sized wad out of the vent cover. We had already had someone clean our ducts, including the dryer duct, from the inside with a snake four months ago, but obviously he didn't get the giant wad at the vent cover. I got great value and peace of mind due to Julio's expertise. Thanks guys!
