Thousands of NW homeowners have trusted TerraFirma Foundation Systems to keep their homes safe, dry and stable since 2005. Nearly half of our business comes from referrals or repeat customers. We can help you too! TerraFirma is the NW expert in home foundations, basement and crawl space waterproofing, concrete leveling, and wall stabilization.
"Original estimate was for just under $4,000 and I was told I would pay extra for anything over the quote, but that it, "probably wouldn't be much, if any." I was thrilled. I immediately signed and cancelled the other estimates I had scheduled. On the day of work, the Technician stopped 1/3 of the way through and stated he used all the foam that was allotted and that any additional work would cost extra. When he was done, my project wound up costing almost $10,000. Voicemails to the project manager went unreturned for a week and a half. Finally received an email after escalating and got a simple email stating that the tech shaved off some cost and that I authorized the additional work. Needless to say, this felt like a bait and switch and left me with an extremely poor opinion of this company. Needless to say, I will never be doing work with TerraFirma again."
