"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."

Patios questions, answered by experts
The costs range from $8 to $20 per square foot, depending on the design complexity, reinforcement needs, and surface finish.
Concrete steps need concrete footings, which is a type of foundation. They are made of concrete with rebar reinforcement poured into a trench. The footings support the stairs, spread the vertical load, and prevent the steps from sinking. Footings need to be below the maximum depth that the ground freezes, typically at least 42 inches in depth.
In most cases, you will need a building permit for cement work on your property. You need a permit for any project that adds a permanent foundation on your property—which, in most cases, includes even a flat slab of concrete poured directly on the ground. Building permits for concrete projects usually cost between $100 and $500, although this can get higher for larger projects. You can always ask your cement company if a permit is necessary for your project, and the expert will typically pull the permit for you to save you time and energy.
While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.
Adding a stamped concrete patio is an affordable way to bring some elegance into your backyard entertaining area, which could add to your home’s value. Provided your stamped concrete patio is installed by a local stamped concrete professional, the patio should last for 40 years or more, and prospective buyers will likely recognize value in that longevity. Keep in mind that permanent patios like concrete slabs will likely raise property taxes, but the added value is usually well worth the investment.
