"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."

"Erik & the team at H & R Waterproofing were very knowledgeable and informative. I would highly reccommend them if you are looking for an honest and transparent waterproofing company. Likewise, it was one of the best deals I found (out of 3 other quotes that I received for similar service). The real test will be the rainy season and winter approaching to see how my two sump pumps handle any water, but I very confident in the work that they have done. My basement looks great. 5 Stars!!"

"Fantastic job. Dependable. They are super honest and skilled. I am a senior woman age 72, and this basement waterproofing challenge was daunting for me, but Dan B. and his crew put my mind to rest. So glad. Thanks so much!!"

"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!"

"Real Pros. They arrived a tad early and I asked them to not start pounding out the basement floor until 8 am. At 8:01 they started. French drain Project finished completely at 12:15. I’ve waited until the next big rain which happened on Monday am. Torrents of rain and basement is bone dry. Exactly as promised."

Basement Waterproofing FAQs, answered by experts

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
