Design & Build Services For Hillsboro, VA

Roofing, Windows, Doors,
Siding, And Much More

Asphalt Roofing

Our asphalt roofing services are designed to give you a strong and sturdy roof that will look gorgeous. We work exclusively with GAF Lifetime Roofing Systems backed with the Golden Pledge standard.


Windows age and ultimately need to be replaced to ensure your home is as energy efficient as possible. We take the guesswork out of finding windows, as we use RJT Industries windows manufactured in Virginia with our climate in mind.


We offer fiberglass entry doors, steel entry doors, and patio door replacements. Our fiberglass and steel doors are made by ProVia, some of the best on the market. Our vinyl patio doors are from RJT Industries.

Vinyl Siding

Our vinyl siding services are meant to give your home a new look with CertainTeed vinyl siding. We chose CertainTeed because it is gorgeous but maintenance-free, includes a lifetime guarantee, has over 40 colors, and offers an insulated siding option.


Our trim services are meant to make your vinyl siding and window installation process even better by ensuring a snug fit. However, the trim used on your home can also be a statement in design. Remember, vinyl siding and window installation must have trim to fit properly.


We install five and six-inch aluminum gutters as part of our gutter services. Often, the installation happens simultaneously with our roofing because the two components of your home work together to direct water away from your house.

Milcon Design & Build Customer Reviews

We Love Hearing From Our Customers

Alex L.

We would recommend Matt and his team to anyone

Matt’s team recently installed new windows through our entire home. Matt took the time to understand our needs and recommend the best window for us at a great price. Took less than a month from when they ordered the windows to install date. He had a whole team arrive for installation and was able to install everything in one day. Any concerns were quickly addressed by Matt. We would recommend Matt and his team to anyone looking for good quality work at a fair price.

Yoko D.

The installation was very efficient and quick

I am very pleased to have Matt and his team help our home to replace our very old 19 windows and the front door. Matt understands our needs very well and provided us with his professional advice to fit our needs and budget. He is also straight to the point ( not too many marketing talks, which liked very much). The quality of the windows and the front door ( with a custom color we requested to keep) is excellent and totally updates our house inside out. The installation was very efficient and quick.

All workers who can to install both windows and the door are very professional and sincere to their work to all details. I would highly recommend his company to anyone considering replacing windows and doors.

Ann C.
