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."

"Schyler arrived at the appointed time explained the the process and how the equipment worked. After he finished he walked me through the completed work. He had cleaned up all the leftover residue explaining if there was any further movement in the work there was a five year warranty and he would return to correct it at no additional cost."

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!"

"This was the third time we’ve used Shepard Painting and again, we couldn’t have been happier with the results. Justin’s crew always pays great attention to detail in the preparation prior to painting, including covering plants and patio. Justin provided a detailed estimate and contract after a walk-around inspection and discussing our concerns. We had some window repair prior to painting and Justin worked with our schedule so that painting began the week following the repairs. After the painting was complete, a crew showed up the next day for any touch-up required and Justin did another walk-around with us to make certain the job was completed to our satisfaction. The crew cleaned up the site daily and Justin was in daily communication with us to address any problems or concerns.

Basement Waterproofing questions, answered by experts

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Yes, you can over dehumidify your house. While you may prefer a dryer climate inside, the elimination of too much moisture in the air can lead to an extremely dry environment that can affect those with respiratory and skin issues. Strike a balance between eliminating excess moisture without making your home feel like a desert. Most modern thermostats show the humidity levels for guidance.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.
