"Job was promised to be less than two days. The crew arrived at the time agreed on and was thorough, covered walls not affected by the work and were finished by the end of the morning. I will recommend AA Action to anyone in need to basement waterproofing, crawl space improvements and related items."

"They work was great. The basement has been dry ever since. Their price was the best of the estimates I received. The service was great and the salesman was great. They didn't make any stains or drop anything. The gentleman came out the same day I called him."

"Brothers Waterproofing did an excellent job sealing a crack in my basement wall. John was very professional and knowledgeable, and that is why I chose Brothers Waterproofing over other contractors. Given I had to rip open my basement walls to fix the crack, I wanted to be sure I employed someone with a sound approach and lasting product so that I didn't have to rip open my walls again. And, John and his team did an exceptional job. They sealed both sides of my basement wall and used quality products to secure the wall to prevent leaking in the future. I would recommend Brothers Waterproofing to anyone seeking out an honest and trustworthy contractor who will stand by his product and promise (which you honestly don't find nowadays). A+ service!"

"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!"

"Roland jr and his crew from MD Waterproofing did a great job under difficult circumstances. A previous renovation by a previous owner dropped the basement floor. What we didnâ t realize is that they had never added underpins so the foundation was undermined. Once Rolandâ s crew broke into a wall to solve a leak, they saw this. They explained the issue clearly and explained the remedy. We were able to quickly get a new quote for the additional work from our company contact, Steve Maney, who was very professional throughout this. Total cost for our house was just over $20k for underpinning two walls and redoing the associated French drains. We will definitely go with MD Water proofing to finish the last two walls, once we have the money saved"

"This was a huge job. A complete basement waterproofing - new internal drains installed and two new sump pumps installed. The guys were great - came on time worked hard all day and cleaned up after themselves. The only negative was at the completion of work when it was time to pay the amount was less than what was originally quoted. I told the guy that and he insisted that it was what he had. I even showed him the quote on paper. I paid it - glad it was less, but a few days later got a call from the office telling me I needed to pay another $1600 (the difference between the original quoted price and at the time of service price) I told her what the guy told me and she got a little rude saying "well you knew what the quoted price was" - yeah I DID know and was prepared to pay but after install HER guy insisted it was the price he had. I wasn't trying to get out of paying but the confusion on how much it costs was with the people working there. I didn't appreciate her attitude as if I was trying to skimp out of paying. Nevertheless, I ended up with this additional payment. However, the work is supposed to be guaranteed for life. No complaints there."

"We are the 2nd owners of a 15 year old home. Don't know why the original owner/builder did not put a sump pump in the basement, as it would have been a cheaper option in the end. If you are building a new home with a basement, put a sump pump in, don't scrimp on what is a very valuable insurance policy. After looking at a handful of other companies to retrofit a sump pump in our cellar, we picked All Aspects Waterproofing, LLC. They did a great job! Very high quality work, and outstanding service. They did a great job! We enthusiastically recommend All Aspects Waterproofing to any homeowner!"

Basement Waterproofing questions, answered by experts

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.
