"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

Customers say: Quality work

"Very pleased with the prompt, friendly service. Very efficient and told me exactly what had to be done and what it would cost in advance. The old, limed up water heater had to be a bear to haul up and out of the basement. It gives me peace of mind knowing that the appliance was installed correctly by an experienced plummer and that it will last for many years to come."

"We purchased our home and the previous owners had Everdry Waterproofing perform work to stabilize the basement walls and waterproof. We have owned our home for 5 years and couldn't be happier with the work that was performed as well as how easy it was to transfer the lifetime service agreement from the previous owner to us. I would definitely recommend this company! Great work!"

Basement Waterproofing FAQs, answered by experts

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.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

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.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.
