If this is the case for you, it is time to consider what you can do to make your home look beautiful and be all you ever wanted. Luckily, we are here to make all your design and build dreams happen!

Matt Kavanah is the owner of Milcon Design & Build. He has 20+ years of experience and has a simple philosophy, only the absolute best will do. On every single job. For every single customer. Down to every single detail.

Here at Milcon Design & Build, we only work with the best roofing materials. That is why we offer GAF Lifetime Roofing Systems that will enhance the beauty of your home while handling the weather in Loudoun County.
The GAF Lifetime Roofing System encompasses all the necessary materials to ensure a solid roof. And you will find several color choices to enhance your home as you see fit.
The beauty of working with the GAF systems is that the manufacturer has trained us to install these to ensure they work correctly for your home. In addition, since we work directly with the company, we often can offer these systems at a much lower price, sometimes as much as 30% lower than competitors.

Windows are not meant to last forever; over time, they become less energy-efficient. We work with RJT Industries to provide windows for homes in the area. Why RJT Industries?
They make their windows right here in Virginia, and we love supporting local businesses. The quality of their windows is perfect for our climate, and they have numerous designs to ensure you find something perfect for your home.

The siding on your home is not only a way to protect the interior of your home but also a way to show your personality and taste. All siding is not made to be the same, so we only use CertainTeed vinyl siding that has been tested to withstand the weather we see in our area.
In addition to handling the weather, it is maintenance-free, a plus for many of our customers. With over 40 colors, you can creatively showcase your personality via your home and up your curb appeal.

Whether you need an entry door or a patio door, we can help hang your new door so it fits snugly and helps your home to be energy efficient. We work with ProVia doors, which are beautiful in design and strong – the perfect combination for any door replacement in your home.

The gutters of your home are often not given a second thought, but they have the critical role of ensuring water is directed away from your home. When your gutters need replacing, we offer 5- and 6-inch seamless aluminum gutters that will hold up against our weather and look gorgeous on your home.

We also handle the trim work when hanging new windows or doors for your home. These small touches make all the difference in the end in how the window or door looks. Plus, we believe the trim is just as much a part of your home as anything else, and when we finish your project, we want it to be beautifully finished.

When it comes to working with anyone in the Sterling, VA, area, we promise a few things to our customers.
Overall, our dedication to our customer service and our ability to ensure no sales tactics and honest opinions is why so many people work with us and recommend us to their friends and family.
We want to make the design and build process so easy that it feels like no stress on your shoulders!

I'm really glad I went with Milcon.Posted on Google Jonelle HillearyTrustindex verifies that the original source of the review is Google. 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!Posted on Google Thomas VolkTrustindex verifies that the original source of the review is Google. 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.Posted on Google Willmer RomeroTrustindex verifies that the original source of the review is Google. 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.Posted on Google Bernadette RahmaniTrustindex verifies that the original source of the review is Google. 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.Posted on Google Meghan KavanahTrustindex verifies that the original source of the review is Google. Excellent customer service. Quick install. Impeccable job. Would highly recommend!Posted on Google Josh EvansTrustindex verifies that the original source of the review is Google. 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.Posted on Google Justin HoughtonTrustindex verifies that the original source of the review is Google. 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!Posted on Google Jorge Manuel TrasmonteTrustindex verifies that the original source of the review is Google. 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.Posted on Google Kristina MilbergTrustindex verifies that the original source of the review is Google. Matt and his team were great to work with, would recommend!
