If you haven’t read it, go check out our Milcon Design & Build origin story. There, you’ll get a very good idea of our experience in the Northern VA exterior contracting world.
Our experience has stood the test of time, bearing the storm of the ups and downs of working for big national brands – especially ones who push high-pressure tactics on homeowners.
In short, we’ve seen it all.
So from the first call to the final clean up… we intimately KNOW what works and what doesn’t. Naturally, we started to take the things that DO work and baked them right into a five-layer lasagna of pure, stress-free, hassle-free exterior remodeling bliss.
Unofficially dubbed “The Milcon 5-Step Master Plan.”
Our 5-step process is our leading guidepost for all services like:

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.

We value communication and responsiveness at Milcon Design & Build, ensuring you’re never left in the dark – in other words, we’ll never “leave you on read.”
Your questions, concerns, and even your ideas are always welcome.
The best part of all? You get to talk to the owner himself during your initial call.
Now if that isn’t a concierge-level way to kick off the best exterior remodel you can get for your money, we don’t know what is!
After your initial call with owner Matt Kavanah, your comfort becomes our top priority.
(Our core values are always on our mind, after all.)
Our hassle-free, absolutely NO pressure 30-minute consultation with the company owner ensures you can discuss YOUR needs without any pushy sales tactics.
We respect your decisions and aim to provide only the information you need to make an informed choice about your home’s exterior services.
Remember how we just said we’ve seen it all? Well… because we’ve seen it all, we know exactly what NOT to do and what TO do.
Looping it back around to the fact that we strive to make your comfort level our top priority – it would go against everything we stand for to manipulate you in any way.
So along with not using poor sales tactics, we also don’t sit around your home, awkwardly waiting for you to decide. Once we conclude your initial consultation, we’re back out the door to email you the quote later!
Imagine that.
You’re able to decide without someone breathing down your neck.

Once you decide you want to continue the stress-free awesomeness of our exterior remodeling process and all contractual logistics are formalized – it’s time for us to really get to work for you.
We’ll immediately spring into action and dive deeper into what you want AND need with our expert advice guiding you every step of the way.
We take the time necessary to understand what you envision for your Northern VA home by discussing your long-term goals, aesthetic preferences, and functional requirements.
We ensure that our proposed solutions align with your expectations – and nothing less.
Because the end goal remains the same – to give you the best damn exterior remodel. Period.
Using the insights from our needs analysis, we’ll provide detailed insight into your window, door, siding, or roofing project. To help you better visualize the outcome, we provide a 3D rendering specific to your home and the service you’ll be getting – be it a roof replacement, replacement windows, entry door installation, or vinyl siding.
We’ll also take this opportunity to measure – down to the millimeter – what we will replace.
This gets us well ready for the next phase, which is the actual installation.


Up until this point, the keen-eyed among you may have noted this. Which is – by this phase in our 5-Step Milcon Master Plan, we haven’t even started the actual installation yet.
Does that mean our process is slower than ‘Craig in a cargo van’, who just rolls up to your property, hammer in hand and ready to go on day one?
Not. At. All.
These first four steps are absolutely essential components to proper due diligence before we begin the serious work.
Look – this is your home we’re talking about. We take it VERY seriously. So… ensuring everything is in order before the first nail is pulled will greatly reduce the chance of any unneeded and downright avoidable issues later.
Depending on your commitment level, we can have your property ready for installation in as little as a few days from your initial call (depending on the scope of your project, of course).
Finally. We’re ready for the best part – the installation.
We’ll use the knowledge, measurements, and your unique needs we learned about from the first four steps to implement our meticulous plan to minimize disruption to your daily life.
We start by double-checking our exact measurements to ensure that perfect fit. Then, we schedule an installation date that suits your timetable.
Our team, identifiable in branded safety yellow shirts, will work efficiently and professionally and keep you updated with regular progress reports. They’ll also protect your property with tarps and other protective measures before the big tools come out.
Once the installation is complete, we’ll enact our ‘not-one-nail-left-behind’ policy where our crew will do a THOROUGH sweep-through of your property – in and out, ensuring EVERYTHING is accounted for and in the same condition it was as when we arrived.

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!
