"None of the companys do the kind of Storm channe system installation work I need. I found a potential resourse by searching for a Mason Contractor on the internet."

"I reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"A superior company. They follow through on their commitments. They have long time employees with great experience. BWN waterproofed our leaky basement about 10 years ago. No problems for almost a decade. After a recent weekend downpour we had water along one of the basement western storm-facing walls. We called and opened a service ticket with Gary. They called back in a little over a day and scheduled a repair at our convenience. Joe, a long time employee, very courteous, professional, and respectful, arrived on the job. He had reviewed our prior project and knew the property well. And it was a window well drain that had clogged. Luckily, it was easily unclogged and the problem was completely solved. We have always been pleased with the work and response of this locally owned business."

"Excellent job all around. The work was done in late March, 2019, but I waited to post this review until after a heavy rainstorm. The storm of July 8, 2019 (>4"/hr) would normally have caused water to seep up through the concrete floor. After the storm, there was not even a drop. The sump was dry. The job was messy: jackhammers and lots of dust. They left it clean. One cannot even see where they cut the lawn to get the pipe to the curb. My only critique is that the new concrete poured to replace the broken floor should have been completely leveled. From initial estimate to installation, excellent work."

"I am SO pleased with this experience with GAC and highly recommend them! OUTSTANDING information and research on our behalf by Kelly for estimate options and finding the best unit and price for our needs. Chris was very impressive when he came to our home for preparation of the HVAC air handler/heat pump installment. Top notch work by John and the GAC crew on the actual work putting in my unit. They gave us the option and were qualified to run/install a new wire for our electric needs to have all energy savings of the equipment. Easy scheduling with Monica and follow-up too. ALL the GAC staff were happy to answer our various questions in full detail so we understood everything in this project and could make informed decisions. GAC found a high quality unit (Bryant) that suited our needs AND qualified for a PEPCO rebate, which they quickly filed on our behalf. We have been customers for years with GAC for maintenance and with this install, plan to be for years to come."
