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."

"These guys were great. I had LP siding and knew from the inspector that it might be a problem. Unfortunately, It turned out NOT to be a simple replace the siding job. I had a lot of damage. They addressed all dry rot, repaired framing and took steps to ensure I won't have this kind of problem in the future with new gutters. Very professional and they clearly knew what they were doing. I did refer my neighbors to them and would recommend them to anyone else."

"Vasiliy is an amazingly talented craftsman with many talents and years of experience. Our nearly 100 year old deteriorating brick chimney was leaking water into the interior of the house and had to be repaired. Vasiliy came highly recommended to me by one of the best contractors in Portland, and I called upon him to fix it. The chimney was red brick, but Vasiliy suggested a lighter, golden color brick as it was more economical. Since our house is yellow, the golden color looked even better than red brick would have, and I saved money. The chimney is beautiful, and the repair/rebuild was so well done that Ithink it will last another 100 years,"

Concrete Leveling questions, answered by experts

A concrete slab costs between $3,600 and $7,200. The price can fall outside of this range if you need a slab that’s thicker than normal, or if you want or need reinforcements, like steel rebar. In some cases, you may be able to purchase a prefabricated concrete slab that is delivered to you already poured.

Visible cracks, scaling, flaking, and uneven surfaces indicate a bad concrete job. Additional signs vary depending on the project. You may notice poor drainage or even exposed rebar. Quality issues result from using the wrong concrete, rushing the work, or inexperienced workers completing the job.

Whether a concrete walkway or sidewalk needs rebar depends on how it will be used. Walkways and sidewalks meant for light foot traffic don’t need rebar, and you can use wire mesh instead. But concrete surfaces that will see heavy machinery will likely need it.

Use a dehumidifier for indoor concrete and a wet vacuum for outdoor surfaces. Sprinkle absorbent materials like sawdust or cat litter to soak up the remaining moisture. If the concrete is outside, simply wait for a few hot, dry days. If the concrete is inside, make sure you have good ventilation for a few days so that any remaining moisture can completely dry out.

Asphalt is not a type of concrete. While both are a common type of pavement, asphalt is composed of aggregates (like sand and gravel) and bitumen; concrete is a mixture of cement, aggregates, and water. Here are some of the key differences between asphalt and concrete driveways.
