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. 

Haugen Finishing the Job with PolyLEVEL Portland, OR

    We have been working with home owner Janet H. of Sherwood, OR since 2009. Her home rests on a property that has been subjected to foundation settlement and soil shifting since she called us years ago, and probably many years before that. Over the years we have permanently stabilized her foundation with a series of push piers and helical piles. This time, Janet had sinking slabs around her property and wanted them fixed without the cost of total replacement. Knowing that we have done great foundation work for her in the past, she called to see if we could help with this type of work. As you could imagine, we were more than happy.

    To solve her sinking slab issue, we first located the voids by drilling through the slab, a hole about the size of a penny, and probing to find the void. Once located PolyLEVEL was injected into the various voids around her property. PolyLEVEL has a high capacity to support and lift sinking slabs without adding extra load to the soils. PolyLEVEL also spreads evenly to achieve uniform lift.

    Over the years we have successfully stabilized, supported and lifted a good percentage or her house and property. With these permanent, durable solutions, Janet can be at ease that her foundation is as stable as can be.

Vicinity of SW Marshal St. in Sherwood
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.

I have a 3 section concrete patio and an end section has sunken about 2 inches. We're hoping to have it leveled.

Some water in crawl space. Sounds when walking in rooms? Settleing?
Vicinity of Orchard Heights Pl in Sherwood
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.

I think there may be roots of a near by Fir tree growing under my foundation. I have a little cracking on one wall by a fireplace. Is this something you do to correct or do I need to contact an arborist?
