    I would not recommend Groundworks for foundation drainage work. I hired Groundworks in the bay…read morearea, California. When I agreed to finance this 15k job, I was told the drainage from the crawl space sump pump would and could be connected to the main, but when the crew arrived they were not sure where the drain exit should go and said the city of Santa Cruz doesn't allow them to connect and they could not get a permit. Why was I not told this prior to scheduling the work? I made the mistake of trying to figure out the discharge area with the workers who showed up. They asked me where I want the discharge pipes, but I am not qualified to make that decision. That is why I hired them. The workers were nice and tried to be helpful and this is not a complaint about them. I called the representative who originally came out, inspected, and estimated the job, which included connection to main, and that is when he told me that he could not get permits from Santa Cruz county. This is when I should have cancelled the job. The completed job by Groundworks has discharge pvc lines on the side of the house and terminating at the front right corner of the house and I have to figure out how and where to drain all of the water! I thought that was the point of hiring an expert drainage company. After work was completed and after first rain of season, I get flooding in my garage on two separate occasions. I spend the day clearing everything out and drying the garage out. I call and a technician comes out to inspect a day later and tells me that the sump pump under the master bedroom was installed backwards and wasn't working. Groundworks installed two new pumps as part of the drainage plan. Mistakes can be made, sure, but I would think for such a pricey job they would have it inspected prior to signing it off. Now that the second pump is up and running, it is so loud that it is difficult to sleep at night, but at least my garage isn't flooding. The noise disturbance now is unsustainable. Now, after groundworks installed this drainage system, if that second sump pump is not on, the garage will flood. Prior, I had one old sump pump under the kitchen and never had this flooding issue. I don't know why, but now my garage floods. Follow up was horrible. The supervisor Wyatt never got back to me when he said he would about the concerns I had and how to resolve them. Initially, Wyatt asked how they could make me feel better. I asked for a discount because at the time I thought the flooding was resolved, but I was put off for over a month and in that time realized it is not exactly clear why the garage floods. My concern is the flooding issue and not the discount, but no follow up to discuss. The General Manager did not call me or reach out as Wyatt said he would refer me to the GM. I had to make contact many times for any reply. At this point I am told by Wyatt that the GM wants receipts of the damage to my garage. I don't have receipts for me clearing out my garage to the driveway and drying out the garage. I called you all when it happened and you sent a technician the following day who told me it was i stalled backwards. A month later after waiting with no return call, I had to call again and was told they came out and fixed it already and would I like it to be inspected again. At this point, by whom? Can I trust this company to tell me what is actually going on? They don't even call me back. Why is the garage flooding now if it doesn't have two sump pumps running when it only had one prior? This treatment feels horrible. I am not out looking for something for free and a discount. I am looking to protect my home from water damage and that is not happening This was a 15k job and I now have to hire another company that can actually tell me why my garage floods. This is not ok. After I seek assessment elsewhere and get a good idea of what is actually going on with the drainage system that was installed, I will be following up with Groundworks. This is a company that stands behind putting out this quality of work and charging for it. 100% disappointed. This situation was improperly handled in many ways. Communication nonexistent.

Shane was the estimator and he did a great job in assessing the site, providing recommendations, educating me on how it all works, and best of all -- adapting to baby quiet hours in the home. I look forward to working with Groundworks in the near future (and will provide a more updated review then)!

Some contractors only walked around the exterior of my home, while others took a quick look underneath. Jon, the field representative from Sunshine Foundation Repairs was different from the moment he arrived. He was on time, friendly, professional, and immediately went into the crawl space to perform a thorough inspection. I was impressed that I received a detailed proposal the very same day. The biggest reason I chose Sunshine Builders was the quality of Jon's inspection. He was the only contractor who identified sagging floor joists in my living room, which likely explained the squeaking floors I had been hearing. He documented the issue with photos and recommended the appropriate repairs, giving me confidence that he was looking out for the long-term integrity of my home--not just trying to sell a standard retrofit. Throughout the entire process, Jon kept me informed every step of the way, from permitting and plan check to scheduling the installation. Communication was excellent, and I always knew what to expect. On inspection day, everything went smoothly. The contractor arrived prepared with all the required paperwork, met with the City inspector, and ensured the inspection was completed without any issues. Jon made an outstanding first impression and represented Sunshine Foundation Repairs exceptionally well. His thorough inspection, attention to detail, clear communication, and guidance throughout the entire process are the reasons why I chose Sunshine Foundation Repairs I would highly recommend them. The proposal bid was right where my budget was.

The crew arrived early in the morning and got started right away. Everyone was in sync and worked efficiently, completing the job faster than I expected. They also left the crawl space clean and removed all debris and trash. I'm very happy with their service and would definitely recommend them.

We were on a time constraint which was appreciated. I was sent an inspector by the name of Golan who was knowledgeable , thorough and professional. He came and did the inspection and did a great job of explaining the result of the inspection to me where I could understand it. I would definitely recommend Sunshine Foundation but I would especially recommend Golan to anybody due to his knowledge and efficiency. I was very happy with the inspection and would recommend them to anyone.

Adam visited my property and spent almost an hour mapping out the entire floorplan and created a detailed plan of attack - all free of charge!!! He carefully measured whether the floor was uneven using a laser, took numerous photos of the areas of concern in the crawl space (wearing a full hazmat suit, goggles, and a high-end face mask), and patiently answered all of my questions. I had another vendor visit the property, and he only spent 3 minutes poking his head around - he did not even enter the crawl space! Therefore, it was an easy choice to go with Sunshine. I felt comfortable enough with Adam to ask him to visit my parents' home for a possible retrofit. Unfortunately, this structure does not have a crawl space / cripple walls and thus is not able to be retrofitted. I feel very comfortable in recommending Adam for other projects, and I look forward to engaging with Sunshine again soon. Thank you, Adam!!
