"Very professional. Great quality work. Very clean and conscientious. Great people to work."

"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."

"Groundworks were contracted to encapsulate the crawl space, with a dehumidifier, intellijacks & sump pump. The inspector showed us pictures & videos of what the work would look like on completion, & explained how each solution would be installed. They tried to charge me more for vent covers until I showed them the contract covering this part. The foreman told me there was a reset button for the sump pump to be installed on an exterior wall, but they did not install it, instead said they would put in a service order. I haven’t heard anything about this issue yet. When they installed the moister barrier, they excluded the cement pads I was told it cost extra to have them covered. When I signed the contract, I was never told there would be extra charges for vent covers or cement pads to be covered. The contract I signed covered a complete encapsulation, but this is not what I got. This is a bait & switch. I would not recommend Groundworks."

"Great. Mark Bonsack did all the work himself. He was true to estimate, even with rain delays and equipment rental. He placed drains,etc. Finish work was great. We would definitely hire again."

"It went very well, he came when promised, installation was done very well. We asked for some additions and they were very reasonable priced. We are very pleased with his work, and would recommend him to any one."

"Very nice work"

"Just had Joes crew work on our yard. They did a great job. Removing weeds and trimming bushes. He is now my go to guy."

"Kent was hired by my next door neighbors(both in their mid-80's) to replace a concrete retaining wall last summer. Prior to the job starting, Kent met with me with someone he introduced as his contracted landscaper. Since our property was downhill from the neighbors, Kent wanted to use our property to remove and replace the wall. He told me the heavy equipment he would have to use would tear up our lawn but that the landscaper would re-sod it. Eight of our stone flower boxes had to be removed to do the job-Kent also was to have his landscaper restore them as well. The demolition and removal of the old wall by crew #1 went fairly well. One of our 12 foot arborvitae did not survive; not sure if that was from crew #1 or #2. Crew #2 was responsible for building the new block wall. The wall was constructed crooked and the locking flange on many blocks was 2 to 3 inches from proper position to lock the blocks together. A good portion of the wall had to be taken down and the blocks placed in proper position. The wall was still crooked, but at least it was locked in place. The wall is supposed to be back filled with gravel-I'm not sure it ever was. But I did see a large amount of garbage (water bottles, the plastic wrap tying all the blocks on the pallets, etc) that probably does not help with drainage. In order to get the blocks back to the job site, a forklift was used. This chipped and broke the front of my driveway where it meets with the street. I wanted to talk to Kent about the damage to my property, but he had planned a 2 week vacation to the Caribbean. The crew boss called Kent on his phone and Kent then informed me that he did NOT have a landscaper but he would still take care of the lawn replacement. I found out that his planned repair of the lawn was to have one of his workers spray grass seed on the previous lawn without any preparation of the site, which was now my old, established lawn that was tore up by the heavy machinery covered with several inches of clay soil. When I told him that was not acceptable, he responded that his contract for this job was not with me but was with my neighbors. I refused to accept the hydroseeding. He did cut the driveway edge straight for me and replaced it with asphalt. Crew #1 was polite, efficient, and left the site clean. Crew #2 was also polite but other than the crew boss, seemed to be inexperienced and made multiple mistakes. Two of my large impact sprinklers were left covered with a foot of soil, an 8 foot section of pipe and a riser and sprinkler was cut off and left laying next to the wall without capping the pipe off-it was later reattached by the neighbor's son. Our house water hose was used by them without permission and the hose was left out strewn across the job site. The neighbors driveway was asphalted with a gutter placed next to the wall. There was a gap between the gutter and the asphalt driveway so water has been draining underneath the gutter rather than into it. So now the asphalt is all collapsing and will soon make the driveway unusable. Now there will need to be additional construction to repair that issue along the approximately 100 foot driveway. Sorry I'm not savvy enough with my phone to be able to attach any of my photos to this review. The neighbor's have been trying to resolve the issues with Kent but to no avail-he has taken payment ($55,000.00!) from them so he is done. And of course he is done with me as well. Never again will I allow anyone to 'use' and destroy my property to make a profit without a separate contract of my own. I would not recommend this business to anyone, ever."
