Fortunately the deviation measurements are within acceptable range and he caution this would not warrant having any work needed. He certainly set our mind at ease. This assessment was offered for free. I appreciate his thoroughness and honest advice. If I have any additional concerns I will certainly reach out to this company.

He identified the sand source as coming from a neighbors yard and over or through a retaining wall. He did a thorough inspection and took measurements from around every room and determined that we were all good and didn't need any work done. Refreshing when a foundation contractor tells you that you are all good. I will not hesitate to call again if there are concerns in the future.

I've spent $50,000 with their company and I'm on my third porch that they poured and removed and repoured and it's still not right. Left huge messes, the house is in the same shape it was when they left here with my money two years ago. I'd never recommend them to anyone and tell anyone I know to avoid them at all cost. My first review was removed because it was too honest. This does not reflect my true feelings!!

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.

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.

The home had some foundation work done in the early 80's but we just new it was time for more leveling. Joe did a thorough assessment, climbing under the house and walking all around it, inside and out, with his level. After inspecting the work that had been done, He was very honest in telling us it did not need the additional work we thought was needed. No telling how much he saved us in his honest assessment. We cannot thank him enough in a specialized service industry that is quite easy to take a homeowner for their money. We have had that happen before so this renewed our faith in good, honest business owners.

Having no expectations to have someone come right out, they were able to get a technician right over within 30 minutes of me calling since one was still in the area.

Not only was he honest but even provided us with a person who does the type of work that we'll need for our house. Didn't use this company but would definitely recommend it!

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.

Luis is amazing and I trust him.
