    Jacob M.

    In May of last year, after days of rain, my basement flooded. After reading a significant number of negative reviews of Groundworks, I decided maybe my situation would be different and gave them a call. It wasn't, and unfortunately, I continue to deal with the effects of hiring them today, nearly 18 months later! Shortly after their salesperson came to the house, I signed the contract to have them install their AquaStop WallSeal and BasementGutter, which would essentially create an interior gutter around about 70% of the perimeter of my basement. They began by removing the bottom half of the drywall and cutting the sole plate connected to the studs (and many of the studs), neither of which I was informed of during the walk through or listed within the contract. This added significant expense when rebuilding the drywall as new plates needed to be secured to the floor. Once removed, demolition of the actual concrete began, and as they jackhammered around the perimeter, they broke pieces of the marble around my basement fireplace and tile flooring near the bar. Unfortunately, the tile isn't sold any longer and I just have a gap now that I haven't figured out how to clean up. The most frustrating part (of the demo) was coming home on the first day of demolition to see custom built-ins in the basement destroyed, despite the fact there is a walk-through and electrical room housing the sump pump that allows for access behind the built-ins! This was the largest unexpected cost I incurred- until the radon issues began. The Groundworks crew does not care about your property. While the demolition proved frustrating and unexpectedly costly, the primary reason I'm writing this review is to inform anyone interested in installing their products to research and determine the impact on their home's Radon. About six months ago, I noticed my existing radon mitigation system making a funny noise so I called a local company (with whom I've been very happy). They informed me of the fundamental incompatibility of radon mitigation systems with the type of system Groundworks installed. What I learned is that by installing a gutter system in your basement, by opening up the foundation you're also allowing the radon to escape without obstruction. Compounding the release of the radon, by removing the concrete, you remove the pressure required for radon mitigation system to work. Importantly, the radon company knew before even testing that the radon level would be high since they knew that installing these systems releases radon. I'm extremely confident Groundworks knows this, too. To address the elevated radon, the first remedy was to install backer rod (basically thin foam pieces) into the part of the basement perimeter that could still be accessed (having already recarpeted the finished parts of the basement). Upon testing, this lowered the numbers only slightly. With the numbers still elevated, I had the radon company install a larger, industrial fan in place of my standard residential. Unfortunately, while this did lower the numbers significantly, radon was still reading over the levels (4pcl) needed. I contacted Groundworks when I realized they caused the radon issue. Eventually, they sent a field manager to review the situation and take pictures. Unfortunately, that was months ago, and despite being told I'd receive a follow-up within a couple of days, I still have yet to get a response, let alone sufficient resolution. At this point, I'm likely to need to install a second system on the other side of my basement to build enough pressure to remove the radon. If this fails, I'm told I'll need to rip up the carpet to allow access around the perimeter where the system was installed and fill in the system Groundworks installed last year. Yes, I'm beyond upset and extremely frustrated with Groundworks, their crew, their management, and their lack of ownership; I'm certain they know their product leads to radon problems and have chosen not to disclose this. Yet most importantly, potential customers need to know this before (ignoring the other poor reviews and) choosing to work with them.

Chase put the bid together on the spot, while thoroughly explaining each line item. There was no attempt to upsell or pressure to make an immediate decision. HomeStrong's bid turned out to be the lowest price, had a great warranty, and included everything we needed. I got a good vibe based on the professional manner in which the bid was prepared. I had a unique issue that required a structural engineer evaluation, which was included in the bid. Lalo and Daner arrived as scheduled to do the crawl space and had to alter the original plan a bit. They completed the project in two days (original estimate was three) and everything was left clean. They were friendly, polite and seemed to genuinely care about making sure I was satisfied. After accepting the bid, I did have to reach out to Chase a couple of times when there delays in communication. He was able to get things moving quickly. Overall, I was very satisfied and can recommend HomeStrong for crawl space encapsulation.

This is an old brick house and the footings are several widths of brick laid directly on the soil, not concrete. The reinforcement is to pour some concrete walls under the footings to support them and to stabilize the soil walls of the tunnels. They also poured concrete to stabilize another area where soil had been eroding under the footing. We also had them remove an unused brick planter next to the wall. The estimator, Lance Heimes, did a very thorough study of the area and then carefully described to us the recommended work. Because of his attention to detail and good explanations I had a lot of confidence in his recommendations. The work went smoothly and looks good upon completion. The weak point with this company was communication. I had to call them up to find out when the work was scheduled, and even then we were never sure when the workers would show up. They also sent me the final invoice for the work when the work was only about half-done, rather than upon "substantial completion" as provided in the contract. They did finish the work a day or two later, so it worked out OK, although for a while I was worried that they had forgotten to finish the work.
