"Yes, the crew (Isaiah, Brian and Austin), were very professional and hardworking. They were fun to have around and they did a great job. They removed the original shims under the girders and carefully replaced them with steel shims. My house now sits on a better and more secure system. I would definitely recommend Thomas waterproofing."

"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."

"A home inspector recommended Taylor Waterproofing, saying it was a quality company that had reasonable pricing. When I called, the owner said he was booked beyond when I needed the work done, but after considering a moment, he said he would get the work done even if it meant working late or over the weekend. He kept in touch, so i never worried that the work wouldn't happen. When I met his team, I was very impressed with their professionalism and their kindness. The work was done well within my time constraints! My crawl space was left perfectly clean; he did way more than I expected. Working with them was a great experience!"

"Maybe I should wait until it rains to make sure everything works (LOL) but I'm so excited about the work Zelica just did in my basement that I felt compelled to review them right away. Every step of the process, from their initial free estimate, to the work itself, to the communication throughout was excellent. We have not always had the best experiences with companies doing work on our house here in Western North Carolina, but Zelica has been amazing. They were always quick to respond to my inquiries, super informative, and fairly priced. They worked their butts off to get our basement waterproofed in less than three days and it looks fantastic (as fantastic as a waterproofed basement can look). Highly, HIGHLY recommend Zelica."

"I chose this company primarily after interviewing several prior customers of Master and actually looking at 3 properties where Master provided waterproofing solutions. All the customers I spoke with spoke highly of Master (except that they, like myself, considered the service was pricey. However, the cost was very much in line with two other contractors, The Foundation Specialists (TFS) and Atlantis Waterproofing. The primary reasons for my selection of Master were: (1) Interviews of prior customers and examination of work performed for them; and (2) the quoted price was in line with the other two other contractors I contacted (TFS) and (Atlantis). Although I requested references from both these firms, I did not receive any further telephone calls, information, or references from either of them."

Basement Waterproofing FAQs, answered by experts

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.

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.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.
