"Very, very disappointing experience; Lux replaced the foundation of my 1850 log cabin. The design was bad, the communication was bad, the execution was bad. Throughout the entire process, they were making mistakes. I now need to pay another company to fix the mess they left behind. I would strongly suggest not using this company!"

Exterior Waterproofing Experts
Exterior Waterproofing Experts
Exterior Waterproofing Experts is a Class A General Contractor in the state of Virginia since 1997. Our service protects your home against wet basements, water leaks, flooding, water seepage, foundation leaking, and wall seepage. We have been doing subcontract grading and drainage work for many years. We have completed many waterproofing contracts for residents of Fairfax County, including: Fairfax, Alexandria, Arlington, McLean, Great Falls, Potomac, and Vienna, Virginia (VA). We are now offering to work directly for clients, passing the savings on to the homeowners. It is our belief that water problems are best solved from the outside before water gets into your home.
"My basement had mold and evidence of water damage in July/August, and I was referred to Exterior Waterproofing Experts. The majority of the mold was on the side of my house, but the salesperson made a strong pitch about the need to waterproof the front of my home by digging up the garden down to the foundation. My wife was largely convinced, so we went ahead with the $8000 project. Six months later, the insulation behind the waterproofed front of the house is sopping wet. When the salesperson came back to my home to take a look, his explanation was that the water probably came up through the floor. His words were along the lines of "99% of the time the water comes up through the front." At this point, I feel like I have an expensive solution to a problem I didn't really have."

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."
