Protect your home from flooding and costly structural damage with professional drainage assessments. Our certified experts use advanced camera technology to identify root intrusion, collapses, and blockages in residential perimeter and storm drain systems throughout the Cowichan Valley.
Foundation Dampness
Visible moisture tracking or white powdery residue (efflorescence) on basement walls often indicates a failing perimeter drain system unable to redirect groundwater away from Duncan homes.
Signs of Perimeter Drain Problems
Yard Pooling & Soil Sinking
Water pooling near the foundation or sinking soil suggest underground drainage lines are blocked by roots or have collapsed. Professional camera inspection services can locate the exact failure point.
Musty Odours & Mold
Persistent damp smells or mold growth along the bottom of interior walls are critical warning signs that blocked perimeter drains are allowing moisture to seep into your home's structure.
