How We Fix Crawl Space Moisture

Every crawl space has its own set of challenges. That’s why our crawl space home interior waterproofing experts begin with a detailed inspection to locate the exact source of moisture. Whether it’s rising damp from the soil, plumbing issues, or poor air circulation, we design a custom solution to keep your space dry, clean, and protected year-round.

Smart Solutions That Last
  • Interior drainage installation: We install crawl space drainage systems that guide water directly to a sump pump for safe removal.
  • Crawl space vapor barrier sealing: Heavy-duty liners keep ground moisture from seeping into your floors and insulation.
  • Moisture and mould control: We use crawl space dehumidifiers and air management systems to stop mould growth and reduce humidity levels.
  • Crawl space encapsulation: We seal vents, walls, and floors to block out outside air, pests, and excess moisture for good.
  • Foundation and structure protection: Keeping moisture out prevents wood rot, sagging floors, and long-term damage to your home’s base.

Looking to understand the crawl space waterproofing cost for your home? We offer affordable crawl space repair services throughout Toronto and the GTA, with honest quotes and no hidden charges. Get a free inspection today and find out how we can give you a cleaner, safer home from the ground up.

Why Do Crawl Spaces Have Moisture Issues?

Understanding the Real Causes of Crawl Space Water Damage

Moisture problems in crawl spaces often go unnoticed until they start to impact your home. You might smell musty air, notice soft or sagging floors, or find mould creeping along your walls. At DGI Waterproofing, we specialize in crawl space moisture control and help Toronto homeowners repair hidden issues before the damage spreads.

Common Crawl Space Water Problems We Fix

  • Groundwater and rain runoff: Heavy rain or melting snow can cause crawl space flooding if exterior drainage is poor.
  • Unsealed dirt or gravel floors: Without vapor barrier installation, moisture rises through the ground and affects your insulation and air quality.
  • Open vents and outside air: Ventilated crawl spaces allow humid outdoor air to enter, leading to condensation and mould.
  • Plumbing and pipe leaks: Even a slow drip from a supply line can cause crawl space water damage over time.
  • Missing drainage systems: Without a crawl space sump pump system or interior drains, standing water has nowhere to go.

If you’re wondering how to fix a flooded crawl space or whether it’s worth it to encapsulate your crawl space for moisture, our team is here to help. In many cases, the problem starts from the outside. Learn more about waterproofing exterior walls to stop water before it ever enters.
