Have To Say

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.

Loren A.

We will certainly recommend them to others

We had Milcon Design & Build replace our roof and they did a fantastic job. Matt, the owner, was great to work with and extremely responsive. He kept us informed until the project was finished. His workers were very nice, but at the same time professional. Everything was cleaned up by them afterwards.

We will certainly recommend them to others. If you give them a call, you'll be glad you did!

Beverley H.
