I highly recommend them for all services

We are very pleased with the work Milcon performed to install our basement sliding door. They were very professional, prompt and very responsive to any questions we had. I highly recommend them for all services you may need. They were also the most reasonably priced of all companies I reached out to. Highly recommend!!

I highly recommend Milcon Design & Build

Matt with Milcon Design & build was extremely impressive with his low pressure professional approach during our estimate visit. He worked with us to change the design a few times to make it perfect. He kept in touch with us during the production of the door, and scheduled a convenient time for installation. The installation crew was on time, courteous, and very professional. I highly recommend Milcon Design & Build.

I will definitely use Milcon Design & Build again!

My journey with Milcon Design & Build began in March 2023, when I was looking for estimates to replace my patio door. I selected Milcon Design & Build after receiving two other estimates, because I was impressed with Matt's professionalism, his ability to answer my (many 🙂 ) questions in detail, and his prompt response. In our initial meeting, he was able to provide suggestions based on my requirements and his previous installation experiences. He then promptly followed up with the promised estimate.

The next meeting was with his technician to verify that they were going to be able to provide the larger size door I requested without causing any structural damage.

Once the door arrived, we scheduled an installation date and time (June 2023). The crew arrived on time, was very professional, and did an excellent job! Once they were done, the technician walked me through the features of the door: the active vs passive side, how to verify that it was closed and looked, etc.

Needless to say, I am more than pleased, the door looks great! I will definitely use Milcon Design & Build again!


Frequently Asked Questions

Does Milcon Design & Build offer roof repairs?

Yes.

While many Northern VA contractors will flat out refuse roof repairs, we make getting your roof up and running again a top priority. Even if that means just a simple repair will suffice.

If you call us with a distressed roof, we will arrive at your home within 24-48 hours (because we understand how pressing roofing issues can be) to inspect the damage.

In fact, we have a whole process dedicated to this – our RoofAssurance program.

How can I maintain my roof after repair or replacement to ensure its longevity?

If you’re doing it yourself, some key areas to inspect and maintain are:

  • Gutters – Make sure they're clear of debris and clear of granules, which indicate deteriorating shingles.
  • Attic – Check to make sure your ventilation is still blowing ALL air outside. Also, you should see NO discolored wood.
  • Trim Obtrusive Branches – Even small branches – when blown onto your roof during a strong storm – can cause damage. Be it from consistent scratching, direct impact, or accumulation of debris in your gutters.
    As such, it’s always best to trim closely overhanging branches above your roof.

How does Milcon Design & Build ensure top-quality home renovation?

Quality is at the heart of our operations. We employ experienced professionals, use high-quality materials, and follow strict installation procedures. Additionally, we back our work with extensive warranties, offering up to 50 years on materials and up to 25 years on workmanship.

What Areas Do You Serve?

We serve many areas in Northern VA and Maryland. Location-specific areas can be found here.
