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."

"I contacted Foundations First NorthWest and a couple of other contractors when an inspection revealed some foundation settling and crawl space damage. I chose Foundations First to make the repairs because they included more work, and at a lower price, than their competitors. I can't say enough about how professional everyone at Foundations First NorthWest was, from the first meeting with the sales rep to the constant communication with office staff throughout the project. Every step was completed without a hitch -- getting permits, engineering, the repair work and county inspections. The work crews worked quickly and efficiently on both the installation of stabilizing foundation piers, and also on the crawl space repairs. And they left the work areas in a very clean condition. I highly recommend Foundations First!"

1-800 Water Damage Portland and Vancouver has more than a decade of experience in providing first-rate restoration services for all problems related to water, fire, sewage, and mold damage. Our technicians are all IICRC and Lead certified, which means that they are able to handle any size restoration job for both residential and commercial applications.

"WARNING!!They will take advantage of you. Save thousands by calling SERVPRO or any other reputable company! I am a business owner with multiple locations. We have always used Servpro when we have had a broken pipe, damaged sprinkler head or septic issue. In the last incident, family friends, who own a local septic clog removal service suggested using 1-800-water damage instead of Servpro, as they heard they were cheaper. The manager did call them. I was shocked at the people who arrived. The appearance of the people was unprofessional to say the least. Next they cam in and asked why are we here as there is no water. I explained the employees had cleaned the water from the broken sprinkler head, and that our concern was with the insulation in the attic around the pipe where we could not get to. They stated they had to get someone to asbestos test the insulation and that would rush that. They then started walking around stating they may need to pull up our WATERPROOF luxury vinyl flooring we had installed only 5 years ago!! I said absolutely not and asked why would you even think that and they said well it could damage the floor under…. Our floors are cement slab and the vinyl was commercial and professionally installed. The water had only come from the pipe for roughly 5 mins before the water was shut off. I knew then that these guys either didn’t know what they were doing, or more likely were looking to make the most money they could off each job regardless of the need. They then walked around chatting finally took some hand held moisture testers which they mostly used while walking not on any of they walls. They ended up leaving many dehumidifiers for a building that had a small amount of water in the front part of the entry only. Three days later they call saying that they have to put multiple holes in our interior walls and pump on air to dry out they walls!!! I asked them why and they said they had detected moisture. I asked them in which walls of our over 6000 sq ft building as none of the walls were wet and they had commercial base on the bottom so only minimal if any water could have gotten at the very bottom only before it was cleaned up. He answer “umm well… all of them” he wanted the punch multiple holes in each wall throughout my building! I said he was being insane. That the water didn’t hit 3/4 of the building. I told him I wanted to see moisture readings from the walls in the back and he said well…. “It’s more that we detected moisture in the hall entryway …. Not on the walls themselves”. I told him that if he where to do this we would have to shut our business down because every room would have big machines. We likely would loose multiple clients and potentially tens of thousands of dollars and then we would have to pay to repair the walls on top of that. There was no way for a small and brief water damage to have caused this devastating result when the floors hadn’t even been exposed to water for most of the building. They had never even tried to take sample or remove the wet insulation which was our only real concern. Finally I told them I was going to call Servpro for a second opinion and this young man then said that it wasn’t up to me! That the building owner had signed off ….. A COMPLETE LIE… I called SERVPRO, who came out stated first, the building had no need for that much dehumidifier. Second that simply removing a small bit of the rubber base cove in the entrance would allow the air to dry the very minimal amount of water on the very edge of the Sheetrock behind the base cove. Additionally, they said that as interior walls that have no insulation in them, that there was no need to put holes in any walls as the water would not accumulate there without insulation to hold it. They said it was clear this company 1-800 was trying to get tens of thousands of dollars from us when it was completely unnecessary. The worst part is they knew we would loose customers possibly have to permanently shut down and had no care they just think oh well that is what insurance is for!"

Basement Waterproofing questions, answered by experts

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

Alternatives to gutter systems include rain chains and drip edges, which work to disperse rain coming off of your roof to a wider section of the ground to prevent erosion and pooling. These options aren’t standalone alternatives to gutters in all parts of the country because they don’t divert water. They’re often reserved for dry climates. On the ground, you can also opt for a drip path or French drain. These can serve as standalone alternatives, but they’re expensive and can detract from your curb appeal and usable yard.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.
