Our home required a few horizontal cracks patched, and a section of the foundation replaced. We also did a complete retrofit in the process. Darren the project manager has been very communicative throughout and just an overall joy to work with.

The foundation of my father's home in Concord was sinking, and we hired Foundation Solutions to…read moreremediate the issue. From start to finish, our experience was outstanding. This is an exceptionally well-managed company, and every step of the process was handled professionally and efficiently. We obtained three bids, and Foundation Solutions was by far the easiest and most competent company to work with. They were willing to work with us on their proposal, and throughout the entire project they demonstrated honesty, integrity, and a commitment to doing things the right way. They use Ram Jack which was minimally invasive. They truly run their organization like a well-oiled machine. Our project manager, Brett Everling, was excellent. He kept us informed every step of the way, from the project planning to the city permits and construction schedule. Communication was outstanding, and everything proceeded exactly as promised (and even a little ahead of schedule). For a project of this size and complexity, it's remarkable that everything went so smoothly. The Foundation Solutions crew was punctual, hardworking, and incredibly diligent. They hand-dug the excavation areas, which was no small task, and they treated the property with care. The amount of concrete that needed to be removed was kept to a minimum, and the concrete repairs afterward were done nicely. We did have one issue with the sprinkler system after it was reassembled, but Foundation Solutions responded quickly and resolved it without hesitation. That level of customer service reinforced that we had chosen the right company.

We just did a mid size project with them last month. We had them underpin one side of the house and…read morereplace a good amount of posts and repair some cracks in our foundation. Brett came out to do an assessment on our entire foundation and his finding was consistent with our own inspection report. Their recommendation is also on par and we find that Brett is quite knowledgeable about the scope of work. He is also very patient, responsive and respectful throughout the estimating project while we took a long time to decide, a lot of follow ip questions and requests. Not once that I felt rushed, pushed or disrespected. The team kept me informed on the timeline of permit, project starting time, inspection and completion, everything was transparent. They passed inspection without problemsx Our foreman is Humberto who was polite, dependable and kept me well informed on the work they performed the day of, when they finished work and provided needed before and after pictures. I also find their pricing is reasonable compared to other companies that we interviewed with the experience that far exceeds their piers. Overall I had a good experience with the crew. They are polite and really didn't interfere with our life that much while they work. I would recommend them for all foundation repair needs. Be careful because lots of foundation companies will scam you, just because you will not be able to see what they did underneath your crawl space. The last foundation company came out to fix our house they made a bunch of noise for 2 weeks, said they are done and then we hired an independent inspector and confirmed they did nothing. Spend the money on a good company. This one is probably the best one ( we interviewed 6 companies)

Part one of a two part foundation project Recently we had…read moreour house foundation repaired by Groundworks out of Fairfield. One bedroom had sunk by almost 5 inches as that part of the house had been built on fill. In order to restore the house to it's proper level numerous foundation jacks and floor leveling screw jacks were required. In addition some landscaping bushes and pvc sprinkler pipes had to temporarily removed. Groundworks had informed me prior to starting work what would be required to successfully complete this project and had my full approval. The house is now level, the doors no longer swing on their own and the interior cracks between the walls and ceiling joints no longer exist. Prior to the crew leaving the yard was cleaned up and the pvc pipes replaced. Best of all Groundworks will come back annually to the next 5 years and make any necessary adjustments. The Groundworks crew that made this happen was Andrew, the site supervisor, Charlie and Allen. Their performance and daily communication was superior on all levels. This is part 2. The Groundworks Poly crew of Anthony & Brian were very fast and efficient in completing their part of the foundation repair contract which was to level our family room slab floor. Fast, yes, but Anthony did take the time to not only explain what they were going to do but also walked me through the process as they were working. I have no problem in recommending them & Groundworks to other home owners who need to have their foundation repaired.

I spent approximately $30,000 with Groundworks, and I deeply regret hiring them…read more I called Groundworks for one reason: contractors working on my floors noticed a slope and told me the beams underneath my house needed to be stabilized before they could continue. Groundworks assessed my crawl space and recommended a system they represented would address the problem. I relied on their expertise. That is the ONLY reason I agreed to spend approximately $30,000. When the project was about 80% complete, Groundworks suddenly told me I needed to call a carpenter. They did not explain that there was significant dry rot underneath my home or that the condition of the wood needed to be addressed before the work they were performing. I learned that later, after hiring an independent home inspector. By then, Groundworks had already been working throughout the same crawl space installing stabilization and encapsulation. My inspector identified significant dry rot and explained that it needed to be addressed first. Had I known that before Groundworks performed approximately $30,000 worth of work, I would NEVER have moved forward with their recommended system before addressing the underlying damage. And here is the worst part: THE ORIGINAL PROBLEM WAS NOT FIXED. The slope remains and appears to have increased since their work was completed. I am now facing additional repairs and expenses, and some of Groundworks' work may have to be undone or worked around to properly repair the underlying damage. The encapsulation has also been problematic. It was supposed to help keep my crawl space dry, but it was not properly secured, leaving openings that allowed rodents into my crawl space. I also later learned that the dehumidification equipment installed did not cover the entire crawl space as I understood it was supposed to. Then there is the customer service. Once they had my money, getting meaningful help became incredibly difficult. I have contacted corporate and have gone more than a month without a meaningful response. If Chris is assigned to your project, based on my experience, I would be extremely cautious. My advice before hiring Groundworks: GET AN INDEPENDENT INSPECTION FIRST. Do not rely solely on the assessment of the company selling you the system. Get everything in writing and ask specifically whether anything underneath your home needs to be repaired before their system is installed. I trusted Groundworks to identify the problem and recommend a solution. Approximately $30,000 later, my original problem remains, the slope appears worse, I discovered significant dry rot that should have been addressed first, I am facing additional repairs, the encapsulation allowed rodent access, and corporate has been unresponsive. I would NEVER recommend Groundworks based on my experience. $30,000 spent. Original problem unresolved. More repairs ahead. That speaks for itself.

(Note however that they provide a rough initial emailed estimate based on house info like sq footage- for an in person inspection there is a fee, but it is credited towards the final cost if you go with them. They do an extra thorough inspection and provide full documentation so in my experience it is worth it even if you don't go with them.) Other free inspection contractors by contrast ran through quickly and provided few to little details on the actual reinforcement plan. My crawlspace had a section of perimeter foundation that was blocked by concrete and required drilling a hole to properly reinforce- none of the other contractors noted this. Avant Garde not only noticed this but also did not charge extra for it. After the work they worked quickly with us on the documentation to get us our grant check. I did crawl the crawlspace just to inspect the work and it was done neatly and the area was left clean. Very happy with the experience and would not hesitate to recommend.
