Get matched with top concrete leveling pros in Marylhurst, OR

"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."

"Excellent and would highly recommend. Jose is professional, quick to respond, and has a network of specialists. He provided us with options for addressing our needs, offered a fair quote, and completed the job in a timely manner. We have used Maximus construction for 3 jobs in the past year and have been impressed by the quality of work. It is a relief to finally have found a company that is dependable, reasonable, trustworthy, and guarantees their work!"

"Great communication and flexibility. The team fixed the sidewalk quickly and exceeded the requirements of the inspector. Highly recommended concrete contractor!"

"Good work done"

"So the concrete foundation was poured but it was missing but it was missing all of our one anchor. There are walls that are too high and too low. They didn't use vibrator on the concrete so there's several places where the concrete didn't settle in and there are exposed rebar. So we hired another engineer to come up with fixes for the problem and the engineer said that the project should take 140 yards of concrete but the contractor ordered 189 yards so there's a lot of wasted concrete."

"Mully was wonderful to work with. He did an excellent job!!"

"SPM showed up exactly on time, ready for work. It's a family business so everyone seemed to know exactly what to do to get the job done. They worked hard and the quality of the finished product was exceptional. I'd hire them again in a minute."

"We needed some posts in our basement replaced with proper footings. TerraFirma was quick to respond and quick to do the work. We are very happy with the result and would recommend."

"It went very well, he came when promised, installation was done very well. We asked for some additions and they were very reasonable priced. We are very pleased with his work, and would recommend him to any one."

"They came out in 2 days to do the work. Other contractors were 3-4 weeks out. They listened to what I wanted and made suggestions to help me decide. The pour went quickly and without incident. The slab came out perfect and the workers were nice and professional. I would highly recommend this company to anyone who wants a high-quality job for a reasonable price. Highest recommendation!"
