James Hardie siding stands as the gold standard in the industry, renowned for its unmatched quality and performance. Engineered to withstand the harshest elements, James Hardie fiber cement siding offers exceptional durability, making it an ideal choice for homes in Centreville. Its resistance to rot, moisture, pests, and fire ensures long-lasting protection for your property, providing you with peace of mind for years to come. Here are some key characteristics and benefits of James Hardie siding:
James Hardie siding is known for its resistance to severe weather, water, fire, and pests. The fiber cement composition helps prevent rotting, warping, and deterioration over time, which makes it more durable than traditional wood siding.
Unlike wood, which can require frequent painting and sealing, James Hardie siding is low maintenance. It often comes with a ColorPlus® Technology, a factory-applied, baked-on color option that provides greater resistance to fading, chipping, and cracking.
The siding is available in a wide range of styles and colors, allowing homeowners to choose options that best fit their home’s architectural style. From lap boards to shingles, the variety of textures and designs can complement any type of home exterior.
Since the material is primarily composed of sand and cement, James Hardie siding is highly fire-resistant, offering better protection against fire than wood or vinyl siding.
Installing James Hardie siding can enhance the curb appeal and overall value of a home. Its durability and aesthetic quality can also be appealing features for potential homebuyers.
Due to these features, James Hardie siding is a popular choice among homeowners who are looking for a reliable, attractive, and low-maintenance siding solution.

Our James Hardie vertical siding options allow you to create a distinctive look that sets your home apart from the rest. Whether you prefer a classic or contemporary aesthetic, our expert team will work closely with you to design and install vertical siding that complements your home’s architecture and reflects your personal style.
Vertical siding, often referred to as board-and-batten, offers a unique visual appeal that can significantly increase the visual interest of your property. This style aligns the boards vertically, creating a tall and clean appearance that can make your home appear larger and more imposing. It’s an excellent choice for adding depth and character to any façade.
Additionally, our vertical siding comes in a variety of colors and textures, giving you the flexibility to tailor the look to fit your desired outcome. James Hardie’s ColorPlus® Technology also ensures that the siding color you choose will resist fading from UV exposure, maintaining its vibrant appearance for years without the need for frequent repainting.

By minimizing thermal bridging and air leakage, our energy-efficient siding solutions can lead to significant savings on your heating and cooling costs, all while reducing your environmental footprint.
James Hardie siding is crafted to provide superior insulation compared to traditional siding materials. This improvement in thermal efficiency not only enhances indoor comfort throughout the year but also contributes to a more consistent indoor temperature, reducing the strain on your HVAC system. Consequently, this can extend the lifespan of your heating and cooling systems due to less frequent cycling and lower overall energy consumption.
Moreover, James Hardie utilizes natural and renewable materials, reducing the environmental impact of their products. Choosing James Hardie siding not only means investing in the longevity and resilience of your home’s exterior but also supporting eco-friendly building practices.

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!
