"The crew worked on our driveway in late July, early August. We’re very dissatisfied on how the job turned out. They cut out the bad section on 30 July and filled it with some sort of gravelly cold patch. The crew came back about a week later and sealed the driveway Problems: They DID NOT seal the gravelly patch area.........actually, they did seal a small portion of it, but that portion cracked within a few days Leads me to believe sealing any of it was a mistake as they must have KNOWN any part of the patch sealed would crack, but, of course, that leaves the driveway unfinished Highly related problem: The patch still has not totally dried, I can still push in on it with my thumb - and the situation is not getting better Hard to see how this job to be anything but a failure - ie, a waste of $3,600 Sign Grace Betts"

"Great job on my retaining wall. Highly recommend. Great price,very professional.Dave & Skylar were super nice. Put yard all back together the way it was.Wall is beautiful!!"

"great guys"

"In spite of the wet weather & access issues they had to deal with, the guys did a great job on the patio & sidewalk concrete work & on the interlocking stone wall. The finishing details on the patio & walkway were exemplary & perhaps some of, if not the best I have seen. I had other contractors working on other projects in the house, & they too were impressed with the job that they did. I would highly recommend Thorp Construction & would most definitely hire them again."

"Originally rated 5 stars, but revised downward to 1 star after company's failure to respond to multiple requests for payment and a copy of our final invoice. Portion of email sent to owner on 10/23/25 follows- "I am relieved that our difficulties with your company occurred after the completion of our driveway paving project on 8/20/25. Your crew did an outstanding job and we continue to praise them and their fine work. Sadly, it is the failure of your company to honor the promises that Joe made on 8/21/25, 8/22/25, 10/2/25 & 10/17/25 to send us a $100 check for work not completed and email or mail us a copy of our final bill that has caused us to reconsider our high praise. I'm glad that business is going so well for your company that you can operate with a business model that does not put a premium on customer satisfaction. I should have believed all the negative reviews that I read online that targeted your company?s frequent failure to respond to customers." "

"They just finished. Very professional. The job looks great. "

"Joe and his crew did an excellent job installing an extensive french drain in my backyard. Joe completed the work quickly and his crew planted grass to bring back my grass. I would recommend this company."

"Frank SanPietro was very professional. He arrived when he said he would and was careful to make sure that he and his crew did a great job. They replaced My entire double width concrete driveway. They installed and raised the steel reinforcement fencing into the middle of the concrete to make sure that the finished concrete driveway was strong. The preparation and finishing of the concrete was exactly as he stated it would be completed. He delayed concrete pouring for expected rain and freezing temperatures, as he should. I fully recommend SanPietro Concrete Construction Company."

"Kieth and his crew widened my driveway and installed new Versa-Lok block walls left and right. His work was of the highest quality, on time and at a fair price. I would recommend Quality Landscapes and Hardscapes to anyone wanting to add to the value of their home. Dennis Bethel Park April, 2025"
