"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."

"Although I did not hire them, I was impressed by their honesty. He explained what the problem was, and told me that it could best be solved by a carpenter, as it was not a cement foundation problem as I thought it was. He also gave a price range of what he thought it would cost. Would hire if I had a problem."

"Central Wisconsin Excavating (CWE) did a fantastic job on our project. They built a solid, well-prepared foundation for our 80,000-bushel grain bin and graded our driveways perfectly to ensure water drains away from our buildings. Their attention to detail, quality of work, and professionalism really stood out. The site was left clean and properly finished, and everything was done right the first time. We’re extremely happy with the results and would highly recommend CWE to anyone needing excavation or site work done right."

"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. Along with that I haven't seen a leak or anything the basement drier than it has ever been and I couldn't thank them enough for all they did. 10/10 would recommend to anyone who needs their basement waterproof or looked at."

"I was concerned that I had mold on my basement walls.  Rich assured me that it was not mold on my basement walls.  However, he did find some mold on the wood on the ceiling.  But he told me that I could wash that off myself and he told me how to do it.  I have medical issues  and my husband is 70 years old.  We are going to try to do this ourselves.  But if we are physically unable to do it, we will most certainly use Rich and his team.  Rich seemed very knowledgeable and was very friendly.  He did not charge me for the assessment even though he took time out of his schedule to come to my house and assess my basement.

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.

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. 

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

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.
