"This was a huge job. A complete basement waterproofing - new internal drains installed and two new sump pumps installed. The guys were great - came on time worked hard all day and cleaned up after themselves. The only negative was at the completion of work when it was time to pay the amount was less than what was originally quoted. I told the guy that and he insisted that it was what he had. I even showed him the quote on paper. I paid it - glad it was less, but a few days later got a call from the office telling me I needed to pay another $1600 (the difference between the original quoted price and at the time of service price) I told her what the guy told me and she got a little rude saying "well you knew what the quoted price was" - yeah I DID know and was prepared to pay but after install HER guy insisted it was the price he had. I wasn't trying to get out of paying but the confusion on how much it costs was with the people working there. I didn't appreciate her attitude as if I was trying to skimp out of paying. Nevertheless, I ended up with this additional payment. However, the work is supposed to be guaranteed for life. No complaints there."

"Exceeded my expectation with waterproofing my entire basement + window wells. These guys are the real deal! I worked with Rob and I was educated and all my concerns were addressed. They do it right by you, the contract missed a window well and they were able to addressed that without having to go through a whole new quote/contract. Helped move some furniture around and left the place clean."

"We had a great experience hiring '58 Foundations to waterproof our basement! Lon was our salesperson, and he came and explained the work that would be necessary to ensure that water would never flood our basement again. We appreciated him taking the time to explain how the whole process worked, and providing us with the option to finance the project to make it affordable for us. We had Brett Boyles and his crew, John and Clarence, come to do the work, and they did a fantastic job! Brett even came to show us the progress in the middle of the project and explained every detail of the work that was being done. He was very professional and we appreciated how he gave us peace of mind about everything once the project was completed. I would highly recommend '58 Foundations for anything basement-related. We appreciate your business - thank you!"

Basement Waterproofing FAQs, answered by experts

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.
