"Based on the foundation being brick, there was not the option to add weeps. Additionally in the middle of February, I did not want to excavate the exterior. Therefore the waterproofing was done from the inside. Renew added a rigid board covering onto the foundation interior which will direct moisture downwards to the new drain tile system and now the basement is humidity and moisture free. Very pleasant folks to work with too."

"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."

"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!"

Basement Waterproofing FAQs, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.
