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!

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!

Yep, another five star review for American Windows…read more We received three estimates for replacing three windows, a French door and a picture window. American Window undercut the estimates of the other two vendors by a substantial margin. We also really liked they only asked for a modest down payment. Jay was our sales contact at American Windows and he was absolutely great. He has an engaging personality, and kept all his commitments to us. We appreciated that when installation day came, he swung by to ensure all was going well. Oh, how did the installation go? It was fantastic. Not only did the windows and door come earlier than promised, the American Windows crew came on time and worked quickly and professionally. We were amazed that the whole job only took 4 1/2 hours to complete. The windows and door materials are high quality and we are very satisfied with the results.

They came out to give me an estimate and once I'd said we wanted them to do the siding, they put me on the schedule. They came out when they said they were going to, they did good work. They took all the old siding away. While they were looking at the siding, they told me they could also do work on our porch (which was in AWFUL shape). I said tell me what your estimate is and I might be able to afford to get some work done. They came back with a reasonable price for refurbishing our porch and they completed it in about a week. I LOVE my porch now. It is safe and BEAUTIFUL. I highly recommend Potomac Roofers and Builders.

Thankfully, everything looked good and I did not require any additional services after the cleaning and tuneup.

For the first time I realize I had been hearing a fair amount of outside noise (which I'd apparently gotten used to), because these windows/doors are soundproof; now I don't hear anything at all from outside! And even better, the windows are easy to open, and my sliding glass doors actually slide well in the track, and are not shaking and drafty when it's windy outside -- major improvements from my old, builder-grade, 20+ year-old windows/sliding door. Further, the service crew was excellent -- careful, kind, professional, efficient, and they cleaned up everything afterwards. Roger, the foreman, has been doing this work for almost 30 years, and Jose, who single-handedly carried in/out the windows/doors, has been doing this work for 10+ years. I didn't get the name of the quiet third service person who was mostly outside and on the ladders, also very efficient. fyi, they did mention that working on the 4th floor of our condos from ladders was a bit more challenging as the original builder-grade windows had been made to fit by being packed/taped in place from the outside, which necessitated them having to actually break some of the glass to be able to pull the old windows out. But they did it - and did it well. Finally, Shaun, the project manager who gave me my estimate and oversaw the project from estimate, HOA approval process, to completion, was great. Highly recommended.
