Double Hung Window Replacement and Repair in Toronto

Double hung windows rely on balance systems, tracks, seals, and hardware that can wear with regular use. We diagnose and repair all common problems to ensure safe, smooth, and reliable operation.

Sashes That Fall or Won’t Stay Open

When sashes drop unexpectedly or won’t remain open, the balance system is usually failing. We repair or replace worn springs, damaged balances, pulleys, or cords to restore controlled sash movement.

Windows That Are Stuck or Painted Shut

Paint buildup, debris, or frame swelling can prevent proper operation. We carefully free stuck sashes, remove excess paint, and realign tracks to restore smooth functionality.

Drafts Between the Sashes

Air leaks often occur where the upper and lower sashes meet. We replace weatherstripping, improve sealing, and adjust sash alignment to eliminate drafts and increase comfort.

Broken or Worn Hardware

Damaged locks, tilt latches, or sash lifts reduce security and ease of use. We install matching or upgraded hardware to ensure safe operation and reliable locking.

Foggy or Failed Insulated Glass

Condensation between panes indicates seal failure. Instead of replacing the entire window, we install new insulated glass units to restore clarity and thermal performance.

Rotted Frames or Window Sills

Exposure to moisture and seasonal weather can cause wood rot over time. We repair or replace damaged sections using durable, rot-resistant materials while preserving the original window style.

Tilt-In Mechanism Issues

If tilt-in sashes won’t open correctly for cleaning, we repair tilt shoes, pins, and jamb liners to ensure smooth and safe operation.

Balance System Failures

We service all balance systems, including coil, spiral, block-and-tackle, and traditional weight-and-pulley designs, restoring reliable performance at every sash height.
