AA Action Waterproofing Inc
AA Action Waterproofing Inc
We strive to exceed your expectations in waterproofing, mold remediation and foundation repair. We take pride in our work, that’s why we don’t employ subcontractors. We understand there are a lot of choices out there when choosing a certified installer – we hope you choose us! Protect your home and health from mold and mildew invaders. In our 28 years of experience, we have never encountered a wet basement, crawlspace encapsulation or mold removal condition that we couldn’t handle. Give us a call today for a free, no obligation inspection and professional basement waterproofing system tailored for your home or commercial project. AA Action Waterproofing is licensed, insured and bonded with a A+ Rating with the BBB. Please call us and we’ll happily supply you with references.
"Our 25+ year-old French drain system in our 100-year-old basement was showing signs of failure, so we contacted several companies to get advice on what to do. Jason of AA Action was very professional and helpful when he performed his initial inspection of our basement, and had very good ideas on what needed to be done. The price he quoted for the work was also, based on what we had read, reasonable. We ended up going with another company recommended by Angi, but only because it brought up a couple of options that we had not thought of, and we felt comfortable with them doing the extra work. We were not at all unhappy with AA Action's suggestions or pricing - it's just that the other company's additional ideas made sense for our circumstances."
