"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."

"We had an internal house line leading to the sewer plugged on a Sunday. We couldn't run any water in the house without it coming out of the drain and into the basement. Based on all the positive reviews I read of KJM plumbing, I called Kurt and he was here within 20 minutes with his machine and cleared the clog, which took about an hour. Pleasant, polite man. The price was reasonable for a weekend emergency call. If I need a plumber again, he'll be the first one I'll call."

"Matt was up front about the cost and understood our policy to obtain estimates from 3 companies before proceeding with work in our home. He itemized the estimate and explained the procedure and warranty. He was pleasant to work with! He did not require an hour of my time or insist that both my husband and I be present in order to give us a sales pitch. The price was competitive and not inflated to cover marketing expenses. I like that the company is family owned & local, and that the workers are employees, not sub-contractors. The men who did the work were efficient and we have had no water in our basement since the waterproofing was done. I believe the contractors who followed Acculevel's work were a little surprised at the materials used, and they had to adjust their plans somewhat, but all is good in the end. Thank you!"

"Only time will tell about the quality and that will tell us whether or not the money was well spent. I will add that the warranty did help us to decide who to go with. The service was very good with the cleanup as well as the office customer service."

Basement Waterproofing FAQs, answered by experts

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
