Basement Remodeling in Wahkiacus, WA

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 remodeled 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 Wahkiacus 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 basement that lasts a lifetime.

Job Stories From Wahkiacus, WA
Falling Insulation, High Energy Costs - Wahkiacus, WA

When high energy bills are present, we like homeowners to evaluate the foundation of the home. Many crawlspaces are not insulated properly. This home had fiberglass insulation strapped to the underside of the home, leaving it open to water weight, creating an ideal place for mold spores to take hold. The water weight had also begun to pull down the insulation, causing a large majority of it to fall to the dirt floor or just hang, leaving the above home colder than it should be. 

To get this home insulated properly, we began with a clean-out. We removed all of the old insulation and cleaned out any debris from under the home. Our installers then installed a SmartSump pump to divert water out and away from the home. The dirt floor was then covered in our TerraBlock crawlspace insulation and the walls were covered with SilverGlo insulation. The entire space was then encased with our 20 Mil CleanSpace vapor barrier. This insulation system was built for crawlspaces so the home can stay dry and healthy, and save the homeowners on their energy bills!

High Moisture Content in Crawlspace - Wahkiacus, WA

This home was experiencing leaking in the crawlspace. The homeowners noticed a significant amount of the crawlspace walls were damp to the touch and they had multiple places where the dirt was mud from the moisture dripping down the foundation walls onto the floors. To solve their waterproofing needs, they called John's Waterproofing. 

To begin the crew cleared out any debris in the crawlspace. They then installed a SmartSump pump to take the water a safe distance away from the homes foundation. The walls in the crawlspace had SilverGlo waterproof insulation installed and then the dirt floor and remained of the crawlspace was sealed up with out 20 Mil woven vapor barrier; CleanSpace. This would isolate all of the wooden aspects of the home from any water damage and also creates a bright and easy to monitor crawlspace so we can inspect it and keep it in tip top shape. The homeowners were very pleased with the new crawlspace encapsulation and were glad they wouldn't need to worry about water damage.
