"Erie Homes completed a basement waterproofing for us on 11/20/23. We were impressed and pleased by the professionalism and communication at every phase of the project. Brandon expertly explained the Erie Homes waterproofing system, sump pumps, materials, and warranty and provided us with a quote and pricing details. Having being burned by projects in the past, we came back with a long list of questions and conditions. Brandon answered every single one, made sure that we were completely satisfied with the terms, and added our notes to the contract. Project manager Gage and the team that came to our home was quick and professional. They periodically filled us in on the progress and communicated any changes or concerns. When the project was completed, they walked us through and made sure we were happy with the work before leaving. Since finishing, we have had several rainy weeks and a completely dry basement. Based on the product, work, and customer service, we will be highly recommending Erie Homes to anyone needing basement or waterproofing work."

"Most of the employees were conscientious Work lasted about a week and was the installation of a waterproofing system in my interior basement. The cement over the drain is very uneven with the existing flooring in much of the area. No way could carpet be used after this. Anyone contemplating this same kind of work should specify floor must be level and ask to see actual material covering the walls, not just pictures to avoid surprises. Clearly much of my disappointment would have been avoided if I had been more fastidious in my specifications and investigations."

"I hired Austin from Clear View Land Management to create a gravel pad for my RV, fire pit and shed. He also leveled part of the lot and put down sod. Excellent communication, beautiful work, honest and hard-working. The work was done in a timely matter and done well for a reasonable fee. I couldn’t have asked for a better experience - thank you."

"The work Everdry performed was excellent and The team was very professional and helpful through the whole process. Even today they are just a phone call away with any questions or anything I have about the work they perfomed in 2021.

"The weather interfered the day they were first to come and utilities didn’t measur and m ark in a timely matter but Rion came on time left when they said they would. They were clean and cleaned up and the workers were nice and considerate, especially with my neighbors I was concerned about hiring a basement waterproofer but I would recommend them without reservation. I love my egress window. What a difference it makes."

Basement Waterproofing questions, 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.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

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.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.
