"I live in Bayonne, New Jersey, and my husband actually spotted the guys from TriStone Masonry & Restoration working a couple of streets away from us and decided to give them a call. I?ll admit, I wasn?t too happy about hiring another contractor at first because we?d had a terrible experience with the last company we used and had been messed around quite a bit. But I have to give these guys credit ? they completely changed my mind. From the moment they started working, they were professional, respectful, hardworking, and showed us exactly what they were doing. They repaired the liners on our front step, got everything looking right again, and repainted the step beautifully. The finished result is absolutely stunning. Every single one of the guys was lovely to deal with, and you could see that they genuinely cared about doing the job properly. By the end of it, they had completely won me over. I?m actually looking forward to finding something else around the house for them to fix!"

"They explained their system and the installation process in detail. They were very flexible and worked with our schedule to finish installation of French drain system before sale of house. Extra foundation work was needed, and they did that as fast as possible"

"Pro Rise Construction LLC transformed our old cracked driveway into a beautiful and durable paved surface that instantly improved our curb appeal. The crew also repaired our front steps and added bluestone details that gave the home a luxury appearance. Vinny and Nitin stayed involved during the entire project and made sure every concern was handled properly."

"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"I had a great experience with the asphalt shingle roof repair. The team was professional, arrived on time, and clearly explained what needed to be fixed before starting the work. They completed the repair efficiently, cleaned up everything afterward, and the roof looks excellent. The quality of the workmanship gave me confidence that the repair was done right. I would definitely recommend them to anyone looking for reliable and honest roofing services."

"John and Lou, sales and owner, were fantastic. The crew that came to do the work was professional, polite, on-time, and efficient. I wish I had hired them in 2006 when we did the waterproofing, I am certain they would have steered us toward repairing the walls first. Lessons learned. Don't be me, use Absolute Waterproofing first."
