You read that right. We’ve spent time on the dark side… of sales. You know, the place where “sleazy sales,” “hard sells,” and “high-pressure” meet. Where “bait-and-switch” is a main tactic in the playbook and “hidden fees” are the norm.
Why would we ever admit to such a thing?
Because it led our founder and owner Matt Kavanah to say, “Enough is enough,” and build a Maryland and Northern Virginia exterior remodeling company from the ground up.
And with a zero-sales pressure philosophy as the bedrock to build on.
A philosophy we’ve taken to the nth degree. Because not only do we now avoid The “dark side of sales” at all costs – we actively combat it.
With genuine integrity, honesty, and utmost transparency.
Bottom line: We’ve flipped the script on the exterior contractor sales game. Because with Milcon Design & Build, we’ll only treat you as a person. NOT a dollar sign.

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 utilize state-of-the-art satellite imagery to provide accurate, fixed-price quotes done with pure EFFICIENCY.
Our “lightning-efficient” process dramatically streamlines your free quote without sacrificing on extreme accuracy.
More so, we’re not afraid to give you a truthful quote UPFRONT, unlike so many Maryland and Northern Virginia exterior contractors who surprise you with “unexpected” costs after your project is underway (i.e., when you can’t say no!).
We acknowledge price increases before we begin work. Because you deserve to know how every penny you pay us is spent.
Yes, we realize that title might be a little corny. But we say it because we mean it.
Treating you how we want to be treated (and then some) is paramount to achieving your successful remodel – treatment like fulfilled promises and honesty at every corner.
When we make a promise to you, it becomes our unshakable obligation. We mean what we say, we follow through on what we say, and if any unpredictable events force a small change, we’ll be decisively transparent about them.
That’s why we guarantee our quotes for an entire year.
More than that – we disclose every part, product, and microscopic detail that will go into your home’s remodel before we pull the first nail.
Oh, and if we mistakenly underestimate your project during your free quote?
We’ll eat the cost of our errors. (You can read more about our accountability here.)

If there’s one area where exterior contractors in Maryland and Northern Virginia really show their true colors… it’s with poor communication. Scratch “poor.” Their “communication” can be downright awful to non-existent.
But in true Milcon Design & Build fashion, we take the polar opposite approach. And while, yes, it’s plastered a million times over our website, and we’ve repeated it over and over – we’re going to say it again.
Our owner, Matt Kavanah, is ready for your calls on his personal cell.
Why does Matt do this?
Because it represents our iron-clad commitment to communicating with you through and through. From our initial meeting to the last nail applied.
Don’t get us wrong; we won’t come to your home dressed casually. But, that said and in line with our “polar opposite” approach…
Have you ever noticed a similarity among the sales minions from the big national brands? That’s right – their uniforms. Or even worse – suits and ties. Yea.
It’s all a façade.
Imagine having a dapper salesperson (ahem, ‘Commission Crusader’) from USA ROOFING INCORPORATED, styled hair and all, who’s never touched a nail gun…. lecturing YOU on a major exterior remodel.
Whoa.
Think about it; a salesman who wears a suit and tie to sell you a roof replacement is NOT a professional roofer.
That’s why when you deal with Milcon Design & Build, our professionalism and expertise come not in a suit and tie, but through our unwavering professionalism and expertise. 20+ years of exterior remodeling knowledge and experience, at that.
Put simply, our professionalism shows up in every step of the process with because we are industry pros at what we do – backed up with over one hundred years of combined exterior remodeling experience.
Add in our streamlined process to top it all off, and our “lack” of Sunday’s best won’t even be a second thought once you experience our true professionalism for yourself.

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!
