Our inspector AJ is great at bringing back photos for the homeowner and, in turn, the marketing department. This crawlspace is not unique. Most of the crawlspaces we see look like this or worse. (I'd venture to bet that most of the crawlspaces in the Pacific Northwest look like this.)

Basement Finishing & Remodeling in Lake Oswego, 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 Lake Oswego 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 Lake Oswego

In Lake Oswego, 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.

Good Evening, We've had two leaks coming from our crawl space into daylight living area and can't determine the source. I'd like a quote to fix the issue. When can you come out? Thank you, -Rich 503-881-2806
Devon Lane in Lake Oswego
The building has a gravity drainage system which includes French drains around the foundation. Water is directed into a sump well in the crawl space before being pumped up to a sewer line. The crawl space has a vapor barrier but is not encapsulated. The sump pump suffers from sediment buildup and seizes regularly, leaving standing water. I may have some mold forming. A radon test was performed in May with an average reading of 0.3 pCi/L. There is a musty smell and I'm concerned about air quality. Forced air furnace is in crawl space. Most supply ducts are insulated, returns are not. I'm planning to install cooling next year and would like to prepare the space as needed. I'm interested in suggestions and an estimate for the work, please. Thanks for your time and help. /bh
