FAQs

Can I waterproof a finished basement?

Yes, but it might require removing and replacing some finished materials like drywall and flooring to access the areas needing waterproofing.

Will my basement require remodeling after installation?

Depending on your situation, major remodeling may not be needed. Anchors can discretely integrate into existing finishing, or post-installation remodeling can be minimal. We’ll determine the best course of action.

Can I save my carpet and padding after a basement flood?

It depends on the floodwater type and duration of exposure. Clean water floods may allow carpets to be saved if dried quickly, but padding usually needs to be replaced. Contaminated water from sewage or outdoor flooding generally requires discarding both for health reasons.
