Job Stories From Hillsboro, OR
Proper Crawl Space Systems Restore Health and Value to You and Your Home

During times in the northwest when it just doesn't seem to stop raining (which is somewhere between 8 and 9 months of the year), do you every worry that your crawl space or basement is improperly waterproofed and water is seeping into your home? A little water won't hurt, but a lot can be detrimental to you, your family and your home's overall health.

Chris A. from Hillsboro, Oregon was experiencing some leakage in the crawl space and is concerned about the long term affects it might have. As this trend continues, you get standing water in the crawl space, which can lead to high levels of humidity and temperature. This will not only rot away at the wooden beams under your home, but can also lead to mold development which become airborne and breathed in by you and your family. 

Chris did the right thing and didn't hesitate to call us for help. By installing an effective drainage system leading to a sump pump for removal and a new 10ml vapor barrier, Chris can now be worry free that he is keeping the family healthy and restoring the value and health to the home.

Foundation repair. Crumbly spots and a couple small cracks.

We have a home built in 1917. The foundation and basement were afterthoughts. An addition was added in the 70s. There are cracks in in the foundation of both plus small cracks in in our walls in various locations throughout the house.
Project Location: Hillsboro, OR
Foundation cracks & undermining, standing water, vapor barrier gaps, construction debris, floor sagging, missing bracket, missing or loose post/pier, & squeaky subflooring were found by our home inspection. We need help determining what we can do ourselves to prevent standing water. We had to buy the home that we were renting this month and don't have much to spend. However, we want to prevent new damage. We wonder if a French drain system would help.
