Leakage Fixing for Windows and Doors

Water ingress and air leaks are more than just a nuisance—they can lead to structural damage, mold growth, and skyrocketing energy bills. At PWG Windows & Doors, we specialize in identifying the root cause of leaks and providing permanent solutions to keep your home dry and airtight.

Whether it’s a puddle on the windowsill after a storm or a persistent draft, our technical team has the expertise to seal your home’s envelope.

Common Causes of Leaks We Fix

Windows and doors are complex systems. When they fail, it is usually due to one of several key issues:

Degraded Seals & Gaskets Over time, the rubber seals (gaskets) that hold the glass in place can shrink or crack due to UV exposure. We replace these with high-quality, UV-stabilized seals to restore a watertight bond.

Blocked Drainage Systems Aluminium frames are designed with internal “weep holes” to channel water outside. If these become clogged with debris or were incorrectly fabricated, water backs up and overflows into your home. We clear, realign, and optimize these drainage paths.

Perished External Sealant The caulking between your window frame and the building’s brickwork or cladding can pull away as the house settles. We remove old, brittle silicone and apply architectural-grade, flexible sealants that move with your home.

Flashing Failures If water is leaking from the top of the window or inside the wall, the issue may be the flashing—the hidden barrier that directs water away from the frame. We perform forensic inspections to repair or replace compromised flashing.

Our Leak Repair Process

  1. Diagnostic Testing: We use controlled water testing to simulate rainfall and pinpoint exactly where the moisture is entering.
  2. Hardware Inspection: Sometimes a “leak” is actually a door that doesn’t close tightly enough. We check rollers and latches to ensure a firm, even compression against the seals.
  3. Precision Resealing: We use premium neutral-cure silicones and commercial-grade gaskets that are specifically rated for the Australian climate.
  4. Glazing Integrity Check: We inspect the “beads” and putty to ensure the glass itself is properly seated within the frame.

Why Act Quickly?

Ignoring a leak can lead to expensive secondary problems, including:

  • Rotting Framework: Water trapped behind the frame can rot timber studs and damage plasterboard.
  • Floor Damage: Persistent leaks can ruin expensive carpets or cause timber floorboards to warp and cup.
  • Energy Loss: If water can get in, air can too. Fixing leaks often makes a room significantly easier to heat and cool.
