I will recommend AA Action to anyone in need to basement waterproofing, crawl space improvements and related items."

"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!"

"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!"

"My husband and I are looking to re-do our basement and install new flooring. We were worried we had leaks/water problems in the basement and scheduled an estimate with Always Waterproofing & Concrete Services to see what the damage is and what we'd have to save up to pay for waterproofing. Jonathan was our evaluator. He was so helpful and focused on assessing the problem over making a sale. Turns out we may not even need waterproofing but instead better ventilation! He advised us that because he didn't see any concerning spots, we should first take up the sub-floor so we can really see what is going on underneath as far as flooding etc. Great customer service, wonderful attitude. You can tell the company cares for your home when they"re more focused on making the proper assessment as opposed to simply making a sale. We'll definitely be referring friends and will call back if we ever need any waterproofing/concrete work. Thanks, Jonathan!"

"We have been working with Affordable for a couple of years now. To put it lightly, we have the basement from hell. When they arrived, we had some water in the basement and they quoted us based on their normal pricing. Once the concrete came up, we couldn't believe what we were dealing with. It is a constant flow of water that required two sump pits and an insane amount of work to install our drainage system. Every time they tried to dig a pit it would backfill with sand and water- they had to dig this up painstakingly- foot by foot. We thought for sure we were in for additional costs, but they stuck by the original estimate. Since then, any time we have had an issue or a question, they are quick to answer. Poor Kelly and Bobby probably recognize our number on the caller ID but whenever we make a call or send an email, we always get a response- usually with a visit on the same day. We highly recommend this company for their honesty, customer service, and quality work."

"We had a basement waterproofing issue. Shopped around a couple of companies. With the best rating on google, and with good reason, Best Buy Waterproofing was our choice. Rob was knowledgeable, diligent, patient and open towards our questions and concerns. Best experience I had with any company rep to date. He came out twice to our place (once the first time to look at the issue, second before he took the work to make sure we all are on the same page.) And then he was there before the work was started to make sure all of us were on the same page. The crew that came out (Darwin, Juan, Raul, Hammie, Chilo) were very careful about their work, respectful, and meticulous. They plastic sealed the work area to prevent dirt, and broom cleaned the area after they were done. Even after the work was done and the transaction was completed, Rob came out to check the work and to make sure it was up to his standard. He olso brought with him the mold treatment up on my request and took care of that as well. Thank you Rob! I highly recommended Best Buy."

Basement Waterproofing questions, answered by experts

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.
