I had them do work on my house a couple of years ago. I like that they weren't out to make my…read moreentire house level but only the worst areas. If they had done that it would have wrecked the plumbing not to mention that I would be left to repair the flooring. Recently, one side of the house started to sink again. They came back out and leveled it back up for free since it was under the lifetime warranty and I kept up with the maintenance. The lifetime warranty makes it worth the expense. Luis is amazing and I trust him.

Luis has been the best with post-work care. I had the entire front of the house lifted in 2022, and…read morehe's been extremely responsive and helpful in the time since (it's now almost 2025). They take care of you after the job, and I don't ever get the sense that they're just in it for the money. They obviously care about their customers and will do what is right, not just what is profitable.

Called to request a foundation inspection, as the home is 30 years old, we have some very minor…read moretile cracks, and do see some seasonal movement in door openings (mostly one upstairs one). Some brickwork is cracked around suspended arches and cornerstone decorative pieces (e.g. above garage doors) but obviously has been for decades. I specifically called Cornerstone because I wanted a serious contractor who does actual poured footings, not that stacked cylinder mess that could actually crack your foundation worse as they use your house for the jack leverage. Dave was on time, courteous and (given that our appointment was in the middle of the Viral Apocalypse) understanding that I was working from home instead of 'off' for the day of our appointment. We spoke for a bit, he outlined everything well and asked pertinent questions about my reasons for calling, then got down to work inspecting...and recommended no work be done at this time. I offered to pay a service charge but he said that wasn't necessary. We did follow up on the phone briefly (I was busy when he was finished) and I am strongly considering coming back to them for some drainage improvements here and there as precautionary measures. Thanks for the time and professionalism.

I accidentally left a positive review because i thought this was the company i selected to do my…read morerepair. I did not. Because they ignored me several times, sent a guy out finally, then ignored me again. I paid another company 13k to do it. So, bang up job keep it up.

Ryan is amazing. It started off with just the backyard and the sides of the house, but eventually…read morewe had him do the front yard as well. We are super happy with the results and how affordable the entire job was. Thanks again, Ryan. If anyone we know or if we ever need work done again, we will definitely be calling you guys. Thanks again.

After receiving an overwhelming quote and a sales pitch from the "O" company, I used FIRM for a…read moresecond opinion. Mason was honest and professional, explained that my home did not have a foundation problem whatsoever and offered irrigation recommendations for future water runoff. Honesty seems to be an anomaly in the foundation industry. FIRM Foundation might prove this prevalence wrong!

Great sales representative. Always keeps up with us on our project. We had to delay our work due to…read moreother priorities.

Big disconnect from sales to field staff, the young man that performed the work was very nice but…read moreVERY inexperienced. Both of these contributed to the field supervisor finally showing up and doing the best he could wrap up the lifting from what had already been done. Unfortunately I paid full price for a "training session", and ending up with mediocre results. As a consumer, 1)do your homework on your project 2) ask lots of questions 3) don't settle... In the future I would be very cautious in using or recommending Groundworks.

I cannot begin to tell you how much I recommend this company! Having a foundation done is an…read moreincredibly big undertaking from both the homeowners and the contractors point of view. From start to finish, they walked me through what was needed financially and the day of the repair. The guys were awesome! I had 17 piers done and it required them to remove and replace bushes, drill into concrete, and even put a pier in the middle of my bedroom! I know that sounds like a lot. They replanted my bushes like they were never gone. Their concrete work is impeccable! I have doors closing now that haven't closed in years! Strong A+ highly recommend!!!

Great company and they really know what they're talking about. I purchased a house that had an…read moreexisting warranty from them on previous work they had done. I was able to transfer the warranty over pretty easily and had them come out to reverify the status of everything. Heath was very knowledgeable and helpful. Dealing with expansive soils is new to me so it helps to have a company that knows what they're doing and stands behind their work. Highly recommend!

We used Jim Starkey, for both our Dallas and Plano inspection. He explained everything to me and…read morepointed out things during the inspection. he was very thorough. I was able to ask him questions during the process. Buying a house is such a big deal so having valid information for the inspection is important! He is quite knowledgeable about many things. Well worth the investment!
