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."

Dillon Rivera and Harlan Gross grew up together in the Pacific Northwest and quickly realized that they made a great team in business. The only issue was finding something that combined both of their passions. As the years passed, Dillon climbed the ladder at a restoration company to become the General Manager, while Harlan took interest in masonry and eventually got into a managerial role in his field. Eventually they both realized that they had the skills and drive necessary to go into business together in restoration and the rest is history. Restoration combined those two passions: helping people and creating a great product. They had observed all sorts of service practices from various trades including masonry, construction, remodeling and more. The main lesson they learned is: It's not worth it in the short or long run to not provide superb service to the customer.

Basement Waterproofing questions, answered by experts

It’s not safe to live in a house with water damage until a trained professional gives you the all-clear to return. Mold can grow within one to two days after water damage and weaken your home’s structural integrity. Always have your home inspected after water damage to ensure it’s safe to live in.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.
