"Upon arrival, we showed Jim the room where we had a terrible odor. He went into the basement area to check for any leaks. Next he identified the toilet as the culprit. The toilet had not been installed properly and a piece below the toilet was cracked not allowing the correct seal. Before fixing anything, we were shown the problem, told what the cost would be, and then after getting the go-ahead, he fixed the problem. It is great to be able to leave that door open! While he was looking for leaks in the basement area, Jim mentioned that the pipes had been located in areas that they should not be. He measured and gave us an estimate on relocating the pipes, which we will have done within the next two weeks. We are extremely pleased with the service we received and would highly recommend Wild West Plumbing!

Basement Waterproofing FAQs, answered by experts

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.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.
