Interior waterproofing involves installing drainage systems (like interior French drains) and sealants on the inside of your basement walls. Exterior waterproofing requires excavating around the foundation to apply waterproof coatings and install exterior drainage systems. Exterior methods are typically more expensive but provide more comprehensive protection.

Quality waterproofing systems can last 10-20 years or more with proper maintenance. Interior systems may require more frequent maintenance (every 5-10 years) while properly installed exterior systems often last longer. The lifespan depends on factors like soil conditions, water table levels, and system quality.

Absolutely. Waterproofing protects your home’s structural integrity, prevents mold growth, and preserves your living space. It typically offers a strong return on investment by preventing costly water damage repairs and increasing your home’s value. Many homeowners recoup 70-90% of the cost in increased home value.

Common signs include: musty odors, visible mold/mildew, efflorescence (white powder on walls), peeling paint, damp spots on walls/floors, standing water, cracks in foundation walls, or bowing walls. Even if you don’t see active leaks, preventative waterproofing can save you from future problems.
