"Seamless experience from start to finish. Todd was super knowledgeable and through on the consult/ sales end. The install team made quick work of the project. Their work was top notch and my basement is now completely dry. I would recommend their services to anyone with basement or foundation issues."

SaniDry Sedona is the world's most efficient, high-performance dehumidifier and filtration system and is a crucial element in basement waterproofing and crawl space repair. As a result of its compact size, it occupies less space in a basement and can easily be tucked away in a crawl space. The unit eliminates damp, musty odors by drying and filtering the air, and it costs less to run than other dehumidifiers. It filters mold spores, dust mite droppings, dust and other particles, and it keeps hu

"Chris, Seth, and the rest of the team did a great job with our basement! They clearly knew what they were doing and were dedicated to finding permanent solutions. Communication was very timely and they kept it in budget. Highly recommend Better Basements and Beyond and plan to hire them again for future projects."

"It has now been a year since we had the waterproofing of our basement waterproofed. I waited this long because with this type of repair I believe you have to wait and see if it did what it was supposed to do. Of course we have had a very dry summer but we have had several heavy rains when it did rain. Please note that the customer service is rated very low: this is only because I have no idea what it is like and no reflection on the actual company in that respect. So hear is what I think: First and for most our basement has stayed dry. However, we had a footer that they replaced all around the base of the walls. We did everything we were told to do and yet there are still numerous cracks in it. My concern is that these cracks will allow the concrete to break. We paid $20000.00 for this fix and now have cracks. Was it worth it? Well we are dry so that's good, but for the money I am very disappointed to see all the cracks! This survey gave me no way to give the answer for post work so all I can go on is pre. The flaw in this is that I can only comment on when they were trying to sell the product to me. I found the salesmen was somewhat arrogant and pushy. We went with this company because we only had 1 other prospect (who we would have gone with, by the way, but despite what the salesman from Mid Atlantic would have you believe, offered the same warranty but wasn't able to get to us in time and we needed the work done)."

Basement Waterproofing FAQs, answered by experts

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.
