"Nothing but good things to say about their work and their workers. Job was done on time and on schedule despite some unexpected “issues” with our neighbors, which they handled with the utmost professionalism. They were very responsive to concerns raised during the job and managed to address some small additional tasks that were uncovered and not part of the initial proposal at no additional cost. Needless to say, I am very pleased."

"John and his team were excellent.  They did a fantastic job.  They came in and sealed a crack we had in the foundation of our home.  It took they about 3 hours.  After reviewing the results of their work, you honestly could hardly tell that an issue existed prior.  They are very good at what they do.  They cleaned up afterwards.  All is good."

"We bought a house in an area with a high water table and discovered flooding and moldy basement walls only days after moving in. Having to rip out a finished basement to waterproof and then refinish was a pain, but worked exactly as advertised. After mold remediation, installing a french drain, battery backed sump pumps, discharge pipes, and structural reinforcements, we finally had a comfortable, dry, and fully usable basement. No musty smell, dry concrete slab and foundation walls. I would hire A-1 again for waterproofing any time."
