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.
"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they “completed the job,” I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they’re saying that leveling the kitchen wasn’t included in the original scope, blaming the remaining dip on my kitchen island and fridge being “too heavy” and lacking proper support—an issue they failed to identify in the initial assessment. To properly address this problem, they’re now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I can’t help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that wasn’t there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as “standard” and providing terms within the contract absolving them—despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to “settle naturally”—a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you’re considering foundation work, I strongly recommend looking elsewhere—this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

Working Year Round serving the Greater Portland Metro area since 1977 in Landscape Design & Installation. We use only the finest materials & guarantee our work. Our crew will work with you to create the perfect Landscape for your location, size and budget. Customer satisfaction is our top priority. Our professional staff can handle just about any project. People truly enjoy working with David in creating their special garden spaces as David has an extensive plant knowledge.
"I had a persistent drainage issue in one corner of my flower bed—flooding so bad I assumed a sprinkler pipe had burst. Dave and his crew came out, dug up the area at no charge, and confirmed that wasn’t the case. He took the time to properly investigate and diagnose the issue, then installed a French Drain that completely resolved the problem. As always, the work was done expertly, efficiently, and to the highest standard. This is exactly why I’ve trusted Dave with my landscaping for the past 7 years. He treats every project like it’s his own home—always recommending what’s actually needed, never upselling or cutting corners. In an industry where it’s easy to exploit customers’ lack of technical knowledge, Dave is the rare pro who builds trust by consistently doing the right thing. We’re long past the point of me asking for bids or details—he tells me what should be done, and I give the green light, knowing it will be done right. SIX STARS!"
