Cornerstone Site Services LLC

I highly recommend Jon for all your demolition needs. After the last heavy snowstorm we had, I heard a large crash and sadly it was the roof of my gazebo collapsing in. My hot tub is inside the Gazebo along with all my stored yard decor and pool chemicals. Fearing the building was going to further collapse onto my nearby pool pump (causing potential water freezing in pool lines and thousands of dollars more in repair) I called Jon whom my niece is dating. Within a day, he was here to look at it and gave me a very fair price. He arrived today and demoed the gazebo. Jon was here for hours in the freezing cold weather and as he took it apart, he had to carry it up hill out my snow and ice covered yard over 100 feet long, out my snowy icy side gate walkway into his dump truck. Jon did it

Could not recommend Cornerstone Site Services LLC enough. From start to finish, the professionalism, communication, and quality of work were top tier. Everything was handled efficiently, the job site was left clean, and the attention to detail really stood out. Jon and his team clearly take pride in what they do, and it shows in the results. It’s hard to find a company that’s reliable, honest, and genuinely cares about their customers — but Cornerstone delivers every time. If you’re in the Philadelphia area and need site services done right, this is your sign to call them. 10/10 experience and I’ll absolutely be recommending them to everyone I know!

I can’t say enough positive things about my experience with John and his company Cornerstone Site Services. He recently helped me with transporting some commercial kitchen equipment. He picked it up and safely delivered and installed it in my business. Fast, easy, efficient, safely. I would definitely recommend John and his company for any of your needs!

Jonathan was great. He took down our 20 years pool a s surrounding deck and pavers. He was honest, hardworking and reliable. I would happily use his services again and highly recommend him.

Jon helped me move a few of my things and it was such a wonderful experience. He went above and beyond even though he absolutely didn’t need to. Super nice guy who’s communicative and extremely polite!
