"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"I've worked with Donnie on several properties to evaluate structural issues, he's always been very professional and thorough with his inspections and identification of structural issues. Recently I had him perform a structural repair on one of my properties that had a tight deadline due to insurance and he got it done without an issue. I would recommend Donnie and Upstate Structural Repair for any structural repairs or consultation!"

"58 foundations came to do waterproofing for my crawl space. The crew was prompt, very professional, and did a fantastic job. They accidently cut an electrical line that no one knew was there...and the service manager insisted on paying for repair...which occurred that afternoon. I was so impressed with their demeanor and their professionalism. They left my crawl space clean and neat. I was very glad I had hired them. I highly recommend this company."
