"We had a fantastic experience with Matrix for our basement project after we got a referral from one of our neighbors. The final product was amazing and everything we could have wished for. From start to finish, they were thorough, organized, and efficient and kept us in the loop every step of way. We always knew what to expect which helped us plan along the way. Ben Gibbons was our project manager and he was very professional and accommodating. He made sure any issue or question we had was addressed in a timely manner and we were always made to feel like the goal was to make us happy at end of day. He also kept everything on track and we finished the project on time. Oscar/Romero were a great carpentry team. I highly recommend Matrix for anyone’s future basement project!"

"We had a small leak that only happened in severe rainstorms. Instead of diagnosing this problem the salesperson wa ted to sell us their complete system. They painted a picture of a poorly constructed basement with many problems. We resisted but finally agreed this was s mistake, because the only problem found after tearing up our basement was a dead sump pump and maybe extra weep holes could have been put in the crock. The original basement drainage system was correctly installed to code. Now our perfect basement floor has permanent scars and we are still fighting the concrete dust leftover from the project. The workers also damaged our vinyl siding and stained it with some type of solvent when cleaning areas that were marred during work. They are probably solve severe basement problems, but we were definitely “oversold”. We made a regrettable error in trusting their expertise."

"Rion waterproofing did an excellent job, they showed up when they said they would. They were extremely clean and considerate. The work was second to none. Very satisfied with the result and couldn't recommend enough."

"My basement had wall crack steps, horizontal cracks, bowing issues along with moisture issues. Water would come in the basement regularly. Everything was taken care of by RENEW about 6-7 years ago. They replaced some of the foundation bricks, installed a drainage system, placed reinforcement rods along the walls and installed a sump pump. RENEW also helped me with additional request as the project progressed (removing personal items, etc). On the exterior they added and pitched dirt along with placing decorative rocks. I’m writing this 6-7 years later so I’m sure I’ve left a few things out. Since having the work done, my basement has been dry. THERE IS NO WATER/MOISTURE PROBLEMS AT ALL! RENEW is a family business that takes pride in their work. They are dependable, personable, reasonable with cost and most of all knowledgeable. Most reviews are done relatively close to when the work is performed. My review is years later which should tell anyone reading this, they do excellent work at a reasonable price."
