"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

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

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.
