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."

Basement Waterproofing questions, answered by experts

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Foundation problems will likely get worse over time if they aren’t repaired. As foundation problems progress, your home may experience signs of structural damage, water damage, and health and safety risks—all of which will only get more expensive to fix the longer you wait. Repair foundation problems as soon as you’re aware of them to avoid complex and expensive remediation in the future.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.
