"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."

"Kevin and his assistant did a series of sidewalk repairs and pours on our sidewalk in Hillsboro -- for us and for neighbors. The work was done professionally and with care and speed. Could not be happier with the result, and the price was right. If my wife and I need more concrete work done, we will look no further and call Kevin at KGS Concrete. Thanks, Kevin!"

"We had a concrete patio removed - Eli was prompt and fair from beginning to end. Would definitely recommend!"

"Very quick response a great communication throughout the entire project. The crew was great at asking questions along the way and made a number of suggestions to improve the outcome and find some savings as well. Would highly recommend with no reservations. We are extreemly happy with the results. I will use them again for upcoming projects."

"Gerardo and the G’s Concrete Crew did a great job on our concrete project. We extended the driveway from parking for two cars to three and added an “RV Pad”. On top of that the crew corrected a front door step and a French Drain that were not up to code. G and his team were easy to work with from planning to prep to completion! They were both polite and professional. They cleaned up after themselves. Pricing was reasonable! They get a 100% A+ from me! I would use and recommend them to friends and family or anyone looking to do a concrete project. "
