"Blalock waterproofing did a fantastic job in my basement. Cory came out, gave an estimate and completed the job of 60 ft of waterproofing in just 6 days. From estimate to completion in 6 days, amazing. He started on Monday and Wed. Afternoon, cleaned up and job down. He dealt with my stairs- they were in the way, and added some additional support to the 4x4s that had been rotted out from all the water at floor level. Final price was exactly what was estimated. Hire them!"

"We highly recommend AFS for waterproofing a crawlspace. AFS encapsulated our crawlspace on our new construction home and installed a sump pump and dehumidifier in the crawlspace. The install crew (Tim - Foreman, Trent, CJ and John) was very prompt, courteous and professional. They explained everything about their work, and thoroughly cleaned up the worksite. Tim returned a few days later to finish up after our electrical outlets were installed and to make sure everything was working properly. Our salesman Reid was also excellent to work with. He explained everything in detail and answered all of our questions."

"David recently came out for a periodic system inspection and promptly replaced a sump pump exit line valve out in the yard that had been damaged by a lawnmower. we discussed adding a backup to the sump pump, which I decided to do. Matthew was out in just a few days to take care of that installation. Everything went quickly and smoothly. These guys are pros."

Basement Waterproofing FAQs, answered by experts

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.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

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.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.
