Basement Waterproofing: Start Here First
Before you finish anything, address potential moisture issues. Even minor water seepage can lead to mold, rot, and ruined materials.
Key Waterproofing Steps
- Seal foundation cracks
- Install sump pumps or interior drainage
- Use water-resistant flooring and wall materials
- Dehumidify the space regularly
Foxura Tip: A reputable contractor will never remodel a wet basement without waterproofing first. If they suggest skipping it, walk away.

In most municipalities, yes. Permits are typically required for:
- Framing
- Electrical work
- Plumbing installations
- Structural changes
- Adding bedrooms or bathrooms
Risks of Skipping Permits
- Failed home inspections during resale
- Fines from code enforcement
- Denied insurance claims if damage occurs
Always check with your local building department. Foxura contractors are required to follow all code and permit regulations.
