Based on recent reviews

“Wow great job. We had basement waterproofing and an egress window installed by AA Action. This was a major project for our family but everything went smoothly. I would definitely recommend this company. The estimator was very professional and did site visits while our job was in progress. The crew was polite and did a great job. The company called Miss Utility to have the area marked where outside digging was necessary. Thanks AA Action Waterproofing.”

“I’m a contractor and had a project in Arlington VA. This company did a great job coordinating the job from start to finish. They provided before and after pictures of the jobs progress. Job site was left clean and most importantly dry. We are now refinishing the basement with peace of mind. I will definitely call them for my next project.”
