"I had 4 companies come out, 2 of them stating I needed a sump pump without even looking outside, or listening to other solutions I had from from other contractors. I HIGHLIGHLY recommend Mastercraft Waterproofing They told me that I absolutely did NOT need a sump pump and it was an issue with the sealing on the outside of the chimney. Water was coming through one of the seams. This was the only company who looked inside and outside on my property. Their work has a lifetime guarantee for what I had done, and saved me $1,000. Tom and Rob are the owners and came out for the quote, and were the ones who did the work. Personable, professional, reliable and cannot recommend them enough. They sent a follow up email for additional recommendations long term, with pictures of the project from start to finish. Please call them if you have water in your basement instead of these large companies who will tell you that you have a huge pool of water surrounding your house. Mastercraft Waterproofing does it all and will be able to help!"

"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"They did a great job. They were able to use a small pump to pump the waste water out before replacing the broken pump. The other company wanted us to pay for a pump truck costing $600 before giving the estimate."

Basement Waterproofing questions, answered by experts

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

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.

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.
