"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! The Sundogs, crew of 3, did a marvelous job of changing my wet and moist basement into a beautiful apartment. Floor was removed and a subcontractor hired to replace the floor after complicated drainage system and sump pumps were installed. Due to the small crew and the complicated problems, it took longer to finish, but I have now a beautiful apartment in my basement. They are dear and honest people who work hard. Thank you Sundogs!"

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.
Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.
Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
