Excellent work very honest and a fair price definitely would recommend them for any roof/gutter/window repair

If you need a roof replacement, go with Milcon for the quality of work, best value and responsive to your questions. I could not get straight answers from multiple roofing companies, Matt is straightforward and doesn’t push you and upsell on unnecessary items. Milcon team will install, not by third party team. Thank you Milcon team!

Matt walked us though a competing quote and understood our priorities of quality and safety while still offering a competitive price. whole process was less than a week after deposit. Installation was around 8 hours. they gave us photos of damaged plywood before replacing. the lead, javier, was very nice and the crew cleaned up well.

I used Milcon to replace 3 sliding doors. I was impressed with the skill, knowledge, and intentionally of the team. While replacing the doors, they found rot behind my siding. I contacted with Milcon to replace my siding and gutters. I am still very pleased with the product, results, and team members. I will work with them again to replace 2 more doors. Here are before and after photos.

We worked with Matt and Milcon on an extensive renovation for our Arlington home including roof, windows, exterior doors, siding and trim - a scope that required lots of decisions from us and him. Throughout the process, Matt was an excellent, honorable contractor to work with: he was fair in his pricing, willing to revise his scope as the project called for it, and made sure that we got the final product we wanted. His crews were punctual and thoughtful - even our neighbors commented on how respectful they were during construction. Finally, when the going got tough (as it often can in a project like this), Matt made sure that the work was done correctly and to our satisfaction. He did not hit us unfair change orders and worked hard to keep the project on time and on budget. I’ve worked with many contractors over the years personally and professionally and would absolutely recommend Matt for any exterior project.

I had a great experience with Milcon and its owner Matt. The estimate, pricing and the scope of work was fair and well explained. I also like that Matt prioritizes quality and didn't go with cheaper but less trusted materials. He explains it very well when giving the estimates.

We recently had new windows and doors installed and couldn’t be happier with the experience. The team was incredibly professional, knowledgeable, and communicative throughout the entire process. They offered a fair price, didn’t try to upsell, and were honest and straightforward. It’s rare to find a company that delivers such quality work with integrity. Highly recommended!

I recently had new windows and a totally revised patio door installed by Matt & Milcon, and I couldn’t be happier with the experience! From start to finish, the team was professional, punctual, and incredibly skilled. Their recommendations led us to a new patio door area changing the flow of the entire house! They took the time to explain the process, answered all my questions, and ensured the installation was seamless. The quality of the windows and door is outstanding, and the installation was flawless—no mess, no hassle. I highly recommend Milcon to anyone needing window & door installation services!!!

It was a pleasure to work with Matt. I generally don’t give 5 stars as I believe there is always room for improvement. However every single aspect of our interaction was fabulous. The quote was right in the middle of the quotes we got, more than that though was how easy it was to work with Matt. He explained everything in detail, was very responsive and the whole thing was done in less time that it took to get quotes. Hopefully we will have an opportunity to use Milcon for other projects.

Matt was great to work with throughout our roof and gutter replacement. He was honest about what needed done and what wasn’t necessary, which was really helpful. He also was patient as I asked a million questions, and explained everything thoroughly. The price they quoted was very fair and a great value for the quality of work they brought to the table. Would highly recommend working with them!

Had a great experience replacing our roof. Matt was quick to respond, explained the process and gave a competitive estimate. The installation crew was very professional and finished the job as scheduled and thoroughly cleaned up any debris. Would definitely recommend Milcon!

Owner Matt Kavanah met with us and explained the process and quality of the ProVia windows, and gave us a very competitive proposal. We got other estimates but kept coming back to Matt's straightforward conversation and the value of the windows we would be ordering. He made some key suggestions that, after the installation today, proved to be great advice. The time from order to install was also very quick. One of the reasons we chose to do a window replacement project now (January) was the cold spots in both our primary bedroom and dining room - opposite ends of our house. Upgraded hvac hadn't been able to overcome the heat loss through old windows and French doors. Tonight, with a new package of high efficiency thermally-broken windows and sliders, we are 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!

Milcon did such a great job with our roof. It was a pleasure communicating and working with them.

Jorge T.Dec 2024

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.

Amy M.Oct 2024

22 windows, a front door, and patio French doors installed. All members of the team were prompt and professional. We are very pleased with the entire process.

Mimi G.Jun 2024

From beginning to end it was wonderful working with Matt (the owner). He was very responsive to any questions or concerns I had. The team onsite was efficient - they finished installing all my windows including a bay window in 1 day! Two screens had small holes so Matt reordered them immediately. I highly recommend Milcon!

Medha C.Dec 2023

Fantastic job fixing up our flat roof - see the pics for the before and after. They cleaned everything up, took off the existing material, and laid down new angled TPO in a single day. Good quality work and quick, professional response times. Highly recommend!!
