"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."

"Replaced driveway ... excellent work ... competitive quote ... arrived early and completed the job ahead of schedule ... ran into a few problems but handled them in a creative manner ... very satisfied and would hire again"

"They went above and beyond to make sure we got what we wanted for a very reasonable price range. The crew was friendly and amazing! They got everything done in 2 days. Cleaned up everything before they left. I really cannot say enough great things about this company! If you are considering having any asphalt paving done, call them first!"

"I highly recommend this company for replacing old concrete steps and walkways! I was very impressed with the efficient communication, discussion of project and the entire execution which took 3 days to complete. Thank you Rick."

"Big thank you to Fermin and the team at West Coast, they were amazing! They went above and beyond. We have a flat portion of our roof, which is apparently more difficult to install, and it was hard to find a company that would do it. They not only did it, but added slope to it for us so that it's not a flat roof anymore. So awesome! They put on a new roof, vents, and gutters, painted our outside trim, and did a great job with all of the woodwork that was rotting and had to be replaced. But above all, they were friendly, flexible and very reasonable. We will definitely call on them again if we have any roofing or painting jobs"

"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!"

"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."

"Excellent communication and education from the team regarding what work needed to be done and the types of materials to be used. Job was done faster than previous re roofs I've experienced and area was left clean upon completion. Thank you!"
