Recent Composite Decking Installation in Gaithersburg

A deck built to last

As a previous client of ours Mrs Stanton already knew who she was working with. We got straight to the design phase of her deck as she wanted to use it in time for Spring. Starting the project in Winter poses it's challenges but ensured the permits, design, and installation were done in time to enjoy the Spring weather. Composite decking boards are only as good as the structure they are built on so our customer elected to use a higher grade of treated lumber for the structure combined with a quality composite decking board. The deck turned out great and they have already hosted a family get together on their new deck.
