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 have used MTU Services LLC twice in the last 3 years. Two projects involving extreme foundation repair for our home in Spokane, WA. Mark and his crew are OUTSTANDING in every way! MTU has old fashion values, no price gouging, detailed bids and the crew is excellent in communication with the home owner while on site each day. Our major repairs took months because the original builder in the 1950's did not put in appropriate footers and a portion of our house began to sink. MTU also completely gutted a basement room that was compromised, jack hammered the concrete out, installed new metal ceiling beams, posts, dug new footers, metal mesh on the floor, poured and leveled the brand new floor. The hardest working real men I have seen in decades and no complaining what soever.

Basement Waterproofing questions, answered by experts

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Mold can grow anywhere in your home where there’s moisture that doesn’t dry out, usually in areas that are either not ventilated properly or where moisture gathers continuously. Insulation, drywall, and foundations typically provide mold with areas to grow if moisture is present and does not have a chance to dry out. Some of the most common areas in a home for mold growth include:

  • Attic

  • Walls

  • Bathroom

  • Crawlspace

  • Basement

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Ductwork sweats for the same reason you might find beading on your windows or why cold drinks drip in the heat—temperature difference. When you see your ductwork and you notice sweating, that's a sure sign that your system is not operating anywhere close to peak efficiency. The best way to keep ductwork from sweating is to wrap it in inadequate insulation.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.
