"I contracted with American Foundation & Basement Repairs, LLC for waterproofing services to include replacing the drywall once the installation was complete. The salesman listened to me, made all the changes that I requested, answered my questions, and did it all quickly, efficiently, and without pressure. The work crews were courteous, cleaned up after themselves, hauled away all the debris, and kept me well informed throughout the process. They called daily to let me know when they would arrive since the repair was not at my residence, giving me plenty of time to get there to let them in the house."

"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."

Basement Waterproofing FAQs, answered by experts

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

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.
