Job Stories From Sherwood, OR
Critters in the Crawl Space Sherwood, OR

    Sherwood, OR home owner Doug K. had some unexpected visitors and has for quite some time. Mice have infested his crawl space, entering through the garage, chewing away at the insulation around piping and nesting in the ceiling insulation. After searching online for a company that could help him with his visiting varmints, Doug called TerraFirma to help.

    To vacate the unwanted company, a complete crawl space encapsulation system was proposed by System Design Specialist Kevin Miller. By isolation the house from the earth with Cleanspace, insulating the walls, and blocking off vents, there is now zero way any mouse can get in or out of the area.

    In completing Doug's encapsulation project, the mice are nowhere to be seen, and he enjoys the added benefits of encapsulation including lower energy bills, less energy consumption, cleaner air circulation and added comfort.

I just purchased this home that is built into the edge of a ravine. I took possession yesterday and discovered that the floors are noticeably uneven in many places and tilting toward the ravine. I'm concerned about the stability of the home and worried that it will fall into the ravine. I need to know if the foundation is stable or if the structure is at risk. This is urgent for me. Thank you for your prompt response.

As a retired architect, I've been aware of the serious seismic risk in the Pacific Northwest for about 5 years now. Our home was constructed in 1974 and, to qualify for a reverse mortgage, we were required to replace the siding. During the upgrade, it was painfully obvious that the structure is woefully unprepared for a major seismic event. In 1974, the severity of the risk was not well-known so, we can't really fault the original contractor or building codes. While we were at it, we also upgraded the windows. With such a significant investment in our home, it would be a tragedy to lose it all to the impact of a major earthquake on an inadequately secured foundation.

Home was built in mid-90's. We just purchased and moved here this September. There's a crack in the garage wall that looks to have been sealed up with some type of glue/caulk, however, first decent rain showed that it leaks. Large puddle in the garage and can see the seal seeping water.

It's not the foundation itself but a concrete patio in the backyard. It has sloped in towards the house pooling water next to the foundation. Additional information: How did you hear about us: Other Main Area of Concern: Foundation

My two-story house was built in 1985. Would like an estimate for strapping house to foundation to keep the house from falling off the foundation since it was built before building codes changed in the 90's. Also have a bedroom over two car two door garage that may be a bigger concern than securing the house to the foundation. We have earthquake insurance but I believe it has a 10% deductible. Depending on cost, it may be worthwhile to do some seismic upgrades on the house. Additional information: How did you hear about us: Internet Main Area of Concern: Foundation
