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."

"We had a complete encapsulation of our crawl space and sump pump and humidifier system installed. The young men who did the work were very professional. Antonio was the project manager and he was fantastic. Answered questions, explained the process, and made sure we were ok with what they were doing. They showed up at the time designated and called if they would be late. Communication was very good. Shout out to his helpers, Daniel, Jesse, and Kameron. At the end of the project they cleaned up the workspace and made sure things were left like it was before project. Thanks guys."

Residential and commercial general contractor with 15+ years' experience in the building industry. No project is too small or too big for Fir Construction!

"The folks at Fir Construction came to my house first thing in the morning just as they said they would. The people were super friendly and went over the plans of my new deck before starting the work. Once they confirmed what I wanted they were on their way. I was in and out of the house all day and they were hard at work. At one point, one of the owners stopped by to check on the progress of the work and say hi. The folks finished the entire deck at the end of day even though it rained during their time at my house. When they were done, they walked me through what they had done. It was exactly what I had wanted. The total price was very fair and their skill level is very high. I would totally recommend Fir Construction to anyone looking for skilled, fast, trustworthy work done on their house."

Foundation Repair questions, answered by experts

You may want to hire a concrete floor contractor to check out your home’s concrete surfaces or inspect your home’s foundation for minor damages that they can fix while on site. They may be able to fix cracks in your driveway or garage floor the same day they fix your concrete steps, as well. General concrete repair experts usually won’t be able to handle larger jobs, like leveling a sunken foundation, so you’ll need to hire a structural engineer for bigger projects.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

It’s usually not an immediate safety risk to live in a house with foundation problems, but you don’t want to let those problems persist. Most foundation issues don’t lead to a house’s sudden collapse, but they can lead to health issues like mold growth and pest intrusion, as well as problems like uneven floors or rotten beams and joists, which can pose injury risks and be costly to fix.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

Always hire a foundation repair contractor the moment you suspect your house doesn't have a good foundation. The longer you wait to address foundation issues, the more likely they can lead to bowing floors, cracks in walls and ceilings, sticking doors and windows, chimney and roof problems, and more. Foundation problems can also let moisture into your home, leading to water damage, mold, and mildew problems.
