    Before

    We hired C2 to replace vinyl siding, as well as provide insulation and house wrap. We also had them replace all our gutters and downspouts and install gutter guarding. The estimate was thorough, pricing explained up front. What we appreciated was their contract - spelled everything out and was easy to understand. The project was quoted at 1 week. They had the job done in 1 week. Workers were respectful and did an amazing job. Kept our yard clean. After the work was completed, a second employee came to perform a final sweep of our property for nails, trash, etc. The work speaks for itself. Our 30+ year old, "buttercream" siding and gutters have been replaced and we couldn't thank the team at C2 enough. Terrific company to do business with and they provide exemplary results.

    C2 was awesome! They are profession, prompt, honest and competitively priced. They delivered on every promise and even when they hit a couple of small snags, they immediately took responsibility for it and corrected the issues in a timely manner. I would hire C2 again in a heart beat and will highly recommend them for any roofing job out there - hands down!

    nice new roof!

    new roof and gutters. came on time, set up, did great work. (i have done roofing in the past so i can say i know the work was great) they cleaned up after. in two days the entire old roof was gone, new roof was on and the mess was gone! then the new gutters came on and wow. my house looks new. also, the workers are very friendly and funny. good guys. made it fun to go out and see the progress as they causally walk along so high up.

    We used them for one job. The beauty of Northern Virginia is that there are so many other contractors out there. Live and let live C2.

    I would totally recommend this window company. I have a big house with about 40 windows that all…read morehave sail failure and need replacement. Because it is a big project, I actually contacted at least 7-8 companies for quotes and ended up using American windows because of their best price and the best windows brand and glass package. Energy efficiency was my priority so I want the best price and best windows which seems to be very hard. But Jay (the project manager) made sure I got what I wanted. The team went out to install 40 windows and they absolutely did an excellent job. They were super friendly and professional. I'm very neat and detailed so they made sure all windows are cleaned and properly installed. After installing, they vacuumed and even mopped the floor for me. I'm very pleased with their work !

    Amazing experience from start to finish! We recently had American Windows replace all the windows…read morein our house and it could not have had a better experience from end to end. Ben was our point of contact throughout the entire project. He came out to take the initial measurements, talk through the project, and generate a quote. It was a complete zero-pressure experience. After receiving the quote I made an appointment to visit the showroom (though Ben also offered to bring some window samples to the house). We really liked the windows (Sunrise Restorations) and moved forward with the project. The installation went flawless! I'm a bit of a perfectionist and usually have to stop myself from nitpicking on small little flaws from general contractors, but American Windows did such a stellar job I couldn't find a single flaw in their work. I'm very happy I went with them!

    I hired Winfield Builders to replace two old skylights in my Rockville home, and Zach and his team…read morewent above and beyond. My project was complicated because my 1980s drywall shafts were the wrong size for modern solar blinds. Instead of just "making it work" or creating a huge mess with drywall dust, Zach proposed a brilliant custom solution: building a clean birch veneer box with custom trim. It looks stunning and kept my house completely dust-free. What impressed me most was Zach's integrity. During the install, a small piece of my old plastic molding snapped. Instead of ignoring it, Zach took full ownership and replaced the trim on both skylights with upgraded foam-backed wood molding at his own expense to ensure everything was airtight and uniform. It is not a simple fix but an upgrade, for free. See the attached before/after pictures and the broken plastic. Like most customers, I contacted a few contractors before selecting Winfield Builders. Their price is VERY reasonable, and the communication through Yelp was professional and transparent. It is rare to find a contractor who cares this much about the details. If you want a crew that is honest, skilled, and delivers a beautiful finish, call Zach. 1000% recommendation!

    I've hired Winfield Builders twice, once to replace my roof in summer 2021 and again in summer 2022…read moreto replace my gutters. Zach made a strong impression from the start--when he came out to inspect my roof and I told him of a problem area, he went up on the roof to look at it! Replacing the roof took only one day, the crew arrived early and worked very hard. I also had the gutters replaced, opting for 6" gutters. The larger size has made a huge difference, as they're less likely to get clogged. My home is in good shape thanks to Winfield Builders!

    We called Loudoun Roofing & Home Improvement because the ridge vents on our roof were damaged from…read morethe wind and potentially leaking. Other companies wanted to send a crew out to just "repair" the cheap aluminum ridge vents that the builder installed, but Esteban recommended a longer lasting solution. He went on the roof, took pictures and showed me the condition of all the vents. He then recommended replacing just the ridge vents with a better quality vent that would last longer and not be susceptible to wind and other damage. When he gave me the estimate, I was pleasantly surprised that the cost was very reasonable. Esteban and his crew came out 2 days later and completed the job it one afternoon. They exactly matched the roofing material we already had, and when they were done the roof looked like new. Not only did they fix the vents, they went around and re-sealed any exposed nails in other parts of the roof AND cleaned out my rain gutters (all just because they were already on the roof). I highly recommend Esteban and Loudoun Roofing & Home Improvement! They were quick, professional and did the work for a fair price.

    Keylah and Esteban were awesome. They function very efficiently as a team and really helped me…read moreunderstand what work needed to be done and then provided pictures of the completed work (who knows if roofers really do what they say!). I live in a 3 story townhouse and had a water leak in a bedroom on the top floor. The house was built in 2014 so I was pretty surprised that I was having an issue. The first "roof specialist" that came over spent 5 min in the attic and then 10 on the roof and told me he couldn't find any sign of the leak or its cause. Just in case, he said he had caulked where he pulled up an exposed nail and that I shouldn't have any more problems. Well, it rained the next day and the ceiling leak got worse. Luckily, I called Loudoun Roofing next and Esteban came out and wouldn't leave until he found the leak. He spent over 20min in the attic (which was like 100+ degrees) and another 30 minutes on the roof. He was VERY thorough and not only found the source of the leak, but also many other issues with drainage and some construction issues. Documenting with pics and descriptions of the work that needed to be done. Long story short, Esteban came out the next week, completed the work and the cost was very competitive with the other roofer that could not find the issue and wanted to do "exploratory surgery". I trust Esteban and Keylah and the work that they do and would 100% recommend to family and friends. Please contact me if you have any questions. I feel like its tough to vet repair companies nowadays, but I will definitely call them for future issues or when I eventually have to replace my roof. I'm a new homeowner in the last 2 years and I cannot describe the peace of mind now that it's fixed...
