Brian came out to assess cracks in our exterior walls and cracks in the interior by our fireplace…read more He walked around the exterior then took measurements from the center of the houses to all corner ponts. 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.

They also added new piers and even found 2 piers missing the previous company charged for but didn't install. They were easy to contact and follow up was good. Quote was about half or less of the other companies.

Originally, we were told the job would two days, but they brought 6 workers plus a crew leader. The foundation work was completed in one day. The crew cleaned up our yard and my neighbor said you could not notice that extensive work had been done. The price was very competitive and I will recommend them to others if asked.

They don't try to upsell you on things that you don't need, and have even told me that I really didn't need any foundation repair on one house that I thought may need work. The company has been around a long time and stands behind their lifetime warranty. They use only the best quality materials, friendly crews, clean up after the work is complete. You will be impressed with the service!

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.

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.
