New windows are designed with energy efficiency in mind. By replacing old drafty windows with new insulated ones you can cut your heating and cooling costs big time. Our Window Replacement in Ashburn is all about energy efficient solutions to keep your home comfortable year round.
Plus energy efficient windows reduce the load on your heating and cooling systems which can extend their life and save you money on maintenance and replacement costs. The improved insulation also minimizes cold drafts and hot spots so you and your family can live more comfortably.
By investing in energy efficient windows you are not only making your home more comfortable and saving on energy bills but also contributing to environmental sustainability. Energy efficient homes have a smaller carbon footprint which is a step towards a greener planet. At Milcon Design and Build we are committed to providing top notch Window Replacement in Ashburn that meets modern energy efficiency standards so you can have a more sustainable and cost effective home.

New windows have a high return on investment (ROI). Buyers will pay more for a home with new, high end windows knowing they’ll get the energy efficiency and style.
New windows make your home look better. Curb appeal is a tie breaker when buyers are comparing homes. Modern, trendy windows give your home a fresh new look that stands out in the market.
In addition to aesthetic and energy efficiency benefits new windows often come with transferable warranties. This added peace of mind is a big selling feature as buyers will love the long term durability and support.
New windows have better locks and are made from stronger materials so you’ll feel more secure if you have kids or valuables.
New windows have features that older windows don’t. Multi-point locking systems lock the window at multiple points along the frame so it’s much harder for intruders to get in. Many new windows also have reinforced frames and sashes to add another layer of security.
Another security feature of windows is laminated or tempered glass. This type of glass is much stronger than regular glass and will hold together even when broken. Laminated glass has a layer of plastic between two sheets of glass making it almost impossible to break through. This added durability also makes your home safer by reducing the risk of injury from broken glass.
Child safety is another consideration in modern window design. Many new windows have child safety latches and vent locks that allow the window to open only a few inches so kids can’t fall out. These features are a bonus for families with young kids.
For those with valuables in the home, new windows are especially good. High security windows will deter burglars so your home is less of a target. Knowing your home is protected by the latest window technology will give you peace of mind so you can feel safe and secure whether you’re at home or away.

If you live in a busy area or near a main road, new windows will reduce outside noise, it will be much quieter inside. New windows are designed with multiple panes of glass, often with gas fills like argon or krypton which greatly reduces sound transmission.
Laminated glass often used in new windows has a sound dampening layer that further reduces noise pollution. This extra sound insulation will make your living space more peaceful and serene so you can enjoy your home without the constant intrusion of traffic, construction or other neighborhood noises. Better noise reduction also means better sleep and overall well being as you’ll be less disturbed by external noise.
At Milcon Design and Build, our Window Replacement Services in Ashburn includes installation of high performance windows that not only improves energy efficiency and security but also noise reduction so your home will be a peaceful haven.
Over time, windows can deteriorate due to exposure to the elements. If your windows are more than 15-20 years old, it’s likely time for a replacement to avoid drafts, leaks, and other issues.
Condensation inside double or triple-pane windows indicates a broken seal, reducing the window’s insulating capabilities. Replacing these windows will restore their efficiency.
Sometimes, the style of your windows may no longer match the rest of your home. Upgrading to new windows can give your home a fresh, modern look.
If you feel a draft near your windows or notice water leaks, it’s a clear sign that your windows are not sealing properly. This not only makes your home less comfortable but also drives up your energy bills.
Windows that are hard to open or close can be more than just an annoyance; they can be a safety hazard. New windows operate smoothly and come with easy-to-use locking mechanisms.

Posted on Google Nolian PapaTrustindex verifies that the original source of the review is Google. Excellent work, and the estimating scheduling process was very quick and hassle free. 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!
