Answers to Your Common Questions
Basement leaks are often caused by poor drainage, cracks in the foundation, heavy rainfall, or aging waterproofing systems. Even high humidity can lead to moisture build-up if the basement isn't properly sealed.
Interior waterproofing manages water once it gets inside—using weeping tiles, sump pumps, and sealants. Exterior waterproofing prevents water from entering in the first place, often by digging around the foundation and applying a waterproof membrane.
Basic interior systems can start around $2,000–$5,000, while full exterior waterproofing can range from $8,000 to $20,000+ depending on foundation size, depth, and soil conditions.
A dry basement protects your home’s structure, prevents mould and mildew, and adds usable living space. It also increases property value and helps avoid costly future repairs.
