The larger your basement, the more expensive it will be to waterproof. This is because larger basements require more materials and labor, increasing costs.

If there is significant water damage in your basement, you may need additional work to repair or replace damaged areas before waterproofing can begin. This could increase the cost of the project.

Moreover, basements constructed with masonry walls may require other measures, such as coatings or chemical sealants for waterproofing.

Time of Year

Contractor Fees

The labor cost can vary depending on the contractor you choose and the project’s complexity. Be sure to get multiple quotes from different contractors to compare costs and ensure you get a fair price.

Mold Remediation
