This customer had a finished basement that was used for kids living space, but without the proper waterproofing system in place they started to get water seepage and leaks down in the kids’ bedrooms! destroying their stuff and leaving it an unsafe place to dwell in. Our team came out and put in a full Watergaurd system and put in our Thermaldry Wall system which will help reflect heat and make the room much warmer for the kids as well. This basement is now warm and dry!

Basement Finishing & Remodeling in Sandy, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Sandy contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

Earthquake & Seismic Retrofitting in Sandy

In Sandy, earthquake risk is a reality. That is why it is critical to have your home properly reinforced and prepared for any seismic event. At John's Waterproofing, we provide seismic retrofitting services on your home or business using metal connectors and other reinforcing methods and materials. The goal is to counteract racking, sliding, and overturning, the 3 major earthquake-induced forces that can damage or ruin your structure.
