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."

At Ram Jack West, we treat customers with respect and care. If you notice cracks, damages, or other issues with your foundation, our team is ready to help. We have innovative systems that have been refined over our 40+ years of experience.
"Purchased a 1906 home in North Portland with an uneven foundation that had been patched for 60 years, but needed serious stabilization work. I contacted multiple foundation contractors in the greater-Portland area and Ram Jack was the only team that provided a full worse-case estimate that included everything that I may need to permanently stabilize the home's foundation. Other contractors' estimates were higher, omitted some of the features of Ram Jack's estimate, and involved greater excavation work around the home. While I was collecting estimates, I had multiple contractors check the levels on the house and could see the home was continuing to sink as much as half and inch in some areas within only a few months, so I knew I had to do something soon as the hotter summers are causing significant erosion to the clay soil in north portland. After paying the 50% down payment, I was quickly in touch with multiple project managers and structural engineers who were able to answer my questions as the work plan developed. I work from home and have two cats, so I was a bit worried about the noise and needing to leave at certain times during the work. Ramjack devised a plan of installing 12 helical piers from the basement and 2 outside for a small crawl space area as well as replacing most of the piers in the basement that had water damage. During the excavation and pier installation, I didn't have to leave my house at all, my cats were fine, none of the utilities ever needed to be turned off and none of the neighbors said they heard more than the hum of the generator outside; insane professionalism. The work team kept me informed at every step of the excavation and pier installation and was able to recover an inch of lift with only a few drywall cracks that I patched in a day. I could have gone further, but wanted to avoid any potential damage to the sewer pipes and stay within my budget. During the lifting, I was standing with the lead construction manager who kept me informed of every risk as we lifted the house bit by bit. During the excavation my basement looked insane with mounds of dirt everywhere, but the construction team cleaned everything flawlessly; all I had to do was a quick mop and the basement was good as new again. Overall had a great experience with RamJack; the 20 years in business shows, most everyone I dealt with had been working with them for years; the construction manager had been doing pier installation for 15 years. The work was expensive, but cheaper than the other local contractors, and certainly way cheaper than replacing the entire basement foundation. Ramjack was even able to take a few grand off the intitial worse-case estimate for solutions not needed. Glad I was able to repair my 120 year old home; here's to another 100 years. Big thanks to Pancho and Stephen, as well as the structural engineers and project managers; I'm very happy with the work."

"We hired SFW to repair our new home that had undisclosed water damage at the time of purchase. TJ was the supervisor assigned to our project and his work was exceptional. TJ is professional, knowledgeable, considerate, kind, thoughtful, courteous, detail oriented, punctual, and always adheres to safety standards. His interpersonal skills are excellent as well. Throughout the entire project, he kept me informed and was transparent about everything related our home restoration. Furthermore, he went above and beyond on multiple occasions to help my family navigate a water damage and new home experience. When we needed documentation of the damage, he helped us by taking 100s of photos. When other new home related projects popped up, TJ was gracious about facilitating the additional projects for us through SFW. We had a gate installed, new hardware installed throughout the house, our cement deck replaced with Timber Tech, and several other small projects that we kept adding to the list! We are extremely grateful to everyone at SFW who worked with us during this 8-month (unexpected) project. Shout out to Jerry, Jay, Jordan, Dominic, Richard, and Jonas! They were also incredibly professional, caring, and helpful during this journey. Jordan was transparent and patient with all things related to billing, Jerry was excellent at managing subcontractors and responsive to our needs as a family. Jerry also provided us a detailed report of SFW findings for our records. Dominic was respectful, professional, kind, detail oriented, and always went above and beyond. TJ and Dominic and other crew members were also incredibly kind to our two dogs and respectful of our privacy in the house. If you are going to have a crew in and around your home, it's sure nice to know they are genuinely professional and considerate human beings. Thank you, TJ, and everyone at SFW! Because of your exceptional work, our home has been restored beautifully. I highly recommend SFW for all your home improvement needs."

If foundation problems are not fixed, not only do repairs eventually become very costly, but it can lead to structural damage to the house above. Eventually, if the foundation problems are allowed to persist, the foundation walls can cave in or collapse. That’s after other issues like flooding and mold have likely been allowed to develop. Although not all cracks are structural problems, some can be and even if they start out small, they can develop into major problems. The earlier foundation problems are discovered and fixed, the lower the cost to repair will likely be.
Yes, foundation repairs are worth the cost at any stage to avoid a dangerous living condition. A failed foundation can lower the value of your home by up to 20%. Whether it’s the smallest problem like a thin crack less than ⅛-inch wide, a horizontal crack, a crack letting water flow through, or a wall bowing inward, repairing foundation problems as soon as possible is worth the cost. Sometimes a temporary fix can be applied until you have the budget to completely fix the problem, but the longer the problems persist, the more costly repairs may be.
The most common first signs of foundation issues include:
Cracks in the foundation walls that grow
Signs of moisture or water leaking through cracks in the foundation
Standing water in the basement
Sagging floors or walls
Cracked walls in upper floors
Doors and windows that don’t close properly anymore
Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
If you’re noticing signs of foundation issues, the first step to fixing a foundation problem is to hire a foundation repair inspector. They will determine the problem, the cause, and the severity before recommending a course of action to repair the foundation. The method for fixing foundation problems depends on the problem and what options are available. A few possible solutions include:
Epoxy injections
Mudjacking
Piers made of steel or concrete
Jacks
Hydraulic piers
Carbon or steel reinforcement strips
Waterproofing materials
