Upgrade your home with premium James Hardie Fiber Cement Siding—built for durability, style, and long-term value. Expertly installed by Milcon Design & Build in Northern VA & MD.
We could only offer one type of siding for our local Northern VA & MD customers, but we’re all about quality-first exterior remodeling materials. And if there’s any name in siding that’s a match made in heaven with top quality – it’s James Hardie Fiber Cement Siding.
What makes James Hardie so good?
Could it be the fact that it’s now securely installed on more than 10 million homes in North America? Or could it be the consistent praise and accolades it gets from dozens of home remodeling associations, publications, and organizations?
Well… if you were to dial up James Hardie themselves, they would likely give you an answer similar to ours – their customers’ consistent 100% satisfaction is what makes them THAT good. But there’s one small catch…
Without a highly-skilled and experienced exterior contractor like Milcon Design & Build to install it, James Hardie’s durable fiber cement siding might as well be tree bark…
But have no fear.
With Milcon Design & Build’s 20-plus years of experience in exterior remodeling, wrapping your home in James Hardie is a skill we’re more than experienced, capable, and confident to undertake.
In fact, it’s one of our favorite materials to work with because of just how high in quality it is.
James Hardie Fiber Cement Siding gives you a beautiful, completely realistic natural wood look and aesthetic – without the common ‘real wood’ problems associated with it.
Because of its molecular composition, fiber cement is impervious to termites, doesn’t rot, and won’t warp. Moreover, its durability is unparalleled, withstanding harsh weather conditions year-round, offering a resilient and long-lasting alternative to traditional wood.
The HardieZone® System offers siding with specific performance attributes relative to the climate where your home is located. In our case, being in Northern Virginia and Maryland, you would get the HZ5 system – engineered for freezing cold and extreme seasonal temperature variations.
So those Northern VA ‘springs with mood swings’ between the extreme hot and cold? It won’t phase James Hardie’s HZ5 one bit.
With ColorPlus® Technology, James Hardie Fiber Cement Siding boasts vibrant, consistent color that lasts longer than a typical paint job. The siding is baked-on in multiple coats in a factory controlled setting for a finish that resists fading, chipping, and cracking. This ensures your home maintains its new gorgeous appearance for years to come.
Oh, and their color selection? It’s massive. But don’t stress. James Hardie has color experts who can help you narrow down your color swatches.
Investing in James Hardie Fiber Cement Siding can lower home insurance premiums due to its fire and impact-resistant properties. Its superior durability and aesthetic appeal can significantly boost your home’s resale value.*
So fiber cement siding isn’t just another ‘run-of-the-mill’ necessary remodel you must take on begrudgingly – it’s an exciting investment in your home’s future.
*Re-siding with fiber cement siding is one of the top ways to increase your home’s resale value, according to Remodeling Magazine 2023 Cost vs. Value report data.
Safety is paramount with James Hardie Fiber Cement Siding, which is why their siding is composed of non-combustible materials that will resist AND won’t contribute to fuel a fire, offering a first line of defense for your home – and your neighbors’ homes.
Its fire-resistant properties provide ultimate peace of mind, knowing your home has an extra layer of protection from this unlikely yet concerning potential scenario.

If there’s one thing Milcon Design & Build Owner and Founder Matt Kavanah dislikes the most about the exterior remodeling industry – it’s overzealous and downright sleazy sales tactics (largely favored by large national exterior remodeling corporations).
Rest assured, there will be no pricing games with your siding replacement when Matt quotes your home’s siding job.
Transparency, reasonable pricing, and the utmost VALUE start with a sales approach that is, well… not a sales approach at all. It’s a SOLUTION.

And more than the beauty and precision of our remodels? The smiles our beyond-satisfied customers have with a job more than well done.

We might sound like a broken record, but it’s because our locality in the DMV is our pride. As a local enterprise, our community is everything to us. It grants us the ability to offer personalized service and attention. This is an attribute the big national guys who play ‘the numbers game’ and nothing else – can only dream of.
We value real, personal, human connection above all.
This connection starts and ends with our surrounding DMV community who we hold so near and dear.

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!
