How do I waterproof my basement before finishing?

By Bob Millaway, South Jersey Community Expert & REALTOR®

Start by checking for existing moisture issues. Install a sump pump with a battery backup if not already present. Apply a waterproofing sealant to walls and floors. Fix any foundation cracks. Ensure gutters and downspouts direct water away from the foundation. Consider an interior drainage system. Do not finish a basement until all water issues are resolved.

Why It Matters

Water damage can destroy a finished basement and create mold problems. Waterproofing before finishing saves thousands in potential repairs down the road.
