"Even though this was a company that did only basement waterproofing work, the company representative was very HONEST. After I described the situation to him, he very honestly told me that the problem was not likely ground water coming in and that I most likely did not need his company's service. He was correct. It ended up being a plumbing issue. I very much appreciated his honesty. If you ever think you may need basement waterproofing services, be sure to consider this honest, trustworthy company."

"Outstanding job by H&R in the waterproofing my basement on February 16. It was Providence as 10 days later a water line in front of my house burst sending thousands of gallons of water cascading toward my house and against the walls of the basement that were waterproofed. The internal french drain and sump pump performed as described by H&R and my basement stayed dry as a bone. We would definitely recommend this business. H&R stands far above other competing basement waterproofers in their honesty and work."

"We had the Steel City crew install the waterproofing system (French drain and sump pump) and wall strap in our basement. They are very friendly and efficient. They finished the project within one day and cleaned up everything. Then they walked us through and explained to us how to check whether the system is working. They also called us to check whether things are going well several days later. BTW, they have lifetime warranty! Very nice experience working with them and I would recommend to everyone!"

"Absolutely miraculous job! They turned our wet nightmare dungeon into a perfectly dry basement! Highest recommendation! We got floor drains, sheeting over our stone foundation, a sump pump and floor drain at basement door. Work was fast, professionally and was exactly what the basement needed."

Basement Waterproofing FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

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. 

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.
