Can you stop my deck or balcony from leaking?
Yes. We inspect the surface, identify the source of the leak, make the needed repairs, and install a waterproofing system designed to keep water out of the structure below.

Most residential projects take about 3 to 5 days, depending on deck size, weather, and whether repairs are needed.
