"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

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

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.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.
