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."

Foundation Drain Installation questions, answered by experts

The process is different for each type of drainage system. But no matter your drainage system type, you’ll have to start by digging a hole or trench. To install an effective French drain, for example, you’ll need to dig a trench, line it with filter fabric, pour gravel inside, hook up pipe connections, set the pipe, and cover it with gravel.

You can use shovels or rent a trencher, depending on the size of the trench or hole you’re digging. You generally don’t need a permit from the city to install a drainage system on your own property, but if the work involves changing a structure or electrical work, contact your municipality to check the requirements.

Some natural springs can dry up, but it’s far from inevitable. In the right conditions, a spring will continue flowing with water. Certain environmental or manufactured factors can threaten a natural spring, however. Hotter temperatures and decreased rainfall can cause a spring to dry up over time, especially in arid places. The same is true if you use spring water for drinking or irrigation faster than the groundwater replacement rate. Keep in mind that there are intermittent springs, which are active on and off throughout the year. They haven’t dried up; it’s all part of a natural water cycle.

Whether interior versus exterior basement waterproofing is better for your home depends on your budget. The majority of water issues that homeowners experience in their basements are due to conditions that start outside of the home. So, to prevent those problems from seeping in, it’s better to stop them at the source using outside waterproofing methods.

French drains are relatively straightforward and cost-effective ways to keep the pressure of standing water from affecting your foundation and remove standing water from your landscape. The installation should last between 30 and 40 years, all the while redistributing both underground and surface water safely away from your home. 

When paired with proper basement waterproofing, a drain protects your home from long-term damage and major flooding during large storms.

It is possible for a slab leak to cause a sinkhole, but it would have to be a particularly serious leak. A slab leak causes the land under your home to erode and if there is enough movement depressions will form in the ground, potentially causing a sinkhole.
