Our Interior Drainage Services

Interior Drain System Installation (Basement)

We install reliable interior drain systems along basement walls, often paired with a sump pump to ensure complete water removal. This is a long-term, maintenance-friendly solution for inside water issues.

Crawl Space Drainage Solutions

Crawl spaces are often overlooked—but they’re extremely vulnerable to moisture. We install crawl space perimeter drainage systems, crawl space French drains, and integrate them with vapor barriers or dehumidifiers when needed.

Crawl Space French Drain Installation

A French drain in your crawl space collects and redirects groundwater before it causes mold, wood rot, or structural damage. It’s a must-have in moisture-prone properties across Vancouver and the Lower Mainland.

What Is an Interior Drainage System?

An interior basement drainage system—also called an internal drainage system—is installed along the inside perimeter of your foundation walls. It captures and redirects water before it can rise through the floor or walls, channeling it safely to a sump pump and out of the home.

Perfect for:

  • Wet or musty basements
  • Basement water leaks after rain
  • Hydrostatic pressure pushing water through foundation cracks
  • Homes without existing exterior drainage

Interior Drainage System Cost

We provide transparent estimates tailored to your specific needs.
Factors that influence pricing:

  • Square footage of your basement or crawl space
  • Depth and layout of the drainage trench
  • Existing water damage or mold issues
  • Type of system (French drain, sump pump combo, etc.)
  • Accessibility and foundation condition

Crawl space French drain installation and crawl space drainage systems generally cost less than full basement systems but deliver significant protection.
