If your deck is leaking water into the space below or holding puddles every time it rains, it’s not just inconvenient, it’s a warning sign. In a city like Edmonton, where freeze-thaw cycles are common, unprotected decks can lead to rot, mold, and expensive repairs.
Luckily, professional waterproofing and drainage repair can solve these problems for good.

Signs Your Deck Has a Waterproofing or Drainage Issue
You might notice:
- Water dripping from the underside after rain
- Pooled water that doesn’t drain properly
- Spongy or softened deck boards
- Water stains on walls or ceilings below
- Musty smell around your foundation
These signs suggest your deck’s slope or waterproofing system is failing.
Purpose: Shows how a leaking deck affects the areas below it, reinforcing the urgency.
What Causes Ponding or Leaking?
In most cases, the problem starts with:
- Poor deck slope – Water can’t drain properly if the surface isn’t angled.
- Old or damaged coatings – Cracked or worn waterproofing no longer keeps water out.
- Gaps in flashing or seams – Where water seeps in undetected.
- Wood absorption – Some untreated wood pulls in moisture like a sponge.
All of these can be fixed with deck sloping and drainage repair services.

Why Standing Water Is More Dangerous Than You Think
Even if your deck isn’t leaking yet, standing water is a warning sign.
- Leads to wood rot and hidden damage
- Creates slip hazards during freeze-thaw cycles
- Promotes mildew and algae
- Weakens surface coatings
- Adds unnecessary weight stress on the structure
