We’re so pleased to be able to provide this review of our recent window replacements project with Milton Design and Build- all in all, truly a 5 star event. Owner, Matt Kavanah, followed up on a Thumbtack request for proposals with a home visit to see what we needed and how Milcon Design and Build could help. Matt explained the process, how long it would take to order and get ready for the installation, and most importantly, what we could expect as performance from the ProVia window and door products recommended for our home. Matt indicated that he would have Project Manager, Josh, come out and take precise measurements to make up the order, but for the proposal pricing he was able to give us a very competitive bid based on our conversation that day. We kept coming back to Matt’s straightforward conversation and the value of the windows we would be ordering. The price and quick time-to-install just sealed the deal. Matt made some key suggestions that, after our installation today, proved to be great advice. One of the reasons we chose to do a window replacement now (January) was the cold spots in both our primary bedroom and dining room - opposite ends of our house. Even upgraded HVAC hadn’t been able to overcome the heat loss. Tonight, with a new package of high-efficiency thermally broken windows and sliders installed, we’re actually turning the thermostat down because we’re warm! Thank you to Matt, Josh, Luis, Martin, and the rest of the crew for a great job, for explaining all the tips and techniques to get the most out of the new windows and front door, as well as to keep them looking beautiful for years to come! Thank you, Milcon Design and Build for working with us on this purchase… you guys are awesome!

Outstanding! After weeks of countless window contractor interviews, we found the perfect company. Matt at Milcon, with his many years of experience, provided us with detailed product descriptions to meet our environment requirements, that included muffling the Ashburn Data Center and air traffic noise. They installed over 40 windows in two days! Most important, my wife is so happy with our choice.

I went to Milcon for a quote and they came in under the competition. The staff was super professional and did everything I asked for. The team was quick and was done within hours. I would go back for any future projects.

Matt was very professional, gave us very good advice for the 2 massive doors we had to replace. We were very happy with the process, the execution of the project and the products. We had a very pleasant experience with Matt and his installation crew. Thank you so much.

Right on time. Matt and his team did what they said they were going to do when they said they were going to do it. Painless process from start to finish. I had a new roof in about 48 hours. Highly recommended.

We were in need of a roof replacement so we threw out a few requests on Thumbtack and I’m glad we did since it brought us to Milcon Roofing. Matt reached out very quick and if I recall correctly came out the following day to discuss options. He wasn’t pushy or trying to just sell me something. It was clear he has been in the business for years and more or less just informed me of my options. He also noted his crew gets certified on the roofing systems which we really liked. So we needed up asking for a quote and it was very fair and competitive. I will say, Matt was very professional, quick to reply to texts, his quote was very fair, and his crew was on time and knocked out the job out in less than one day. Oh, also their clean up was outstanding. While I hope to never see Matt again (since the roof will last many more years than we should be here) I would 100% call him back for any future work here or at our next home. If you need a new roof, give them a call, you won’t regret it!

We hired Milcon Roofing, Design & Build for replacing the original aluminum siding on our house. Matt took the time to explain different options and we opted for the insulated siding. Matt was very easy to work with and communicated with us through the entire process. The work crew did an great job despite some days with rough weather. We are very happy with the results, less cold drafts, a reduction in noise and a more modern looking exterior. Everything looks great! Can't recommend enough.
