When window frames are not perfectly aligned, pressure is unevenly distributed across the structure. This causes difficulty opening or closing the window and accelerates wear.

How to address it:
Professional realignment ensures smooth operation and prevents long-term structural damage.

Poor or insufficient sealing allows air and water to enter the home. This reduces insulation and increases the risk of moisture-related damage.

How to address it:
Removing old sealant and applying high-quality, weather-resistant seals restores protection against drafts and leaks.

Windows that are not securely anchored can shift over time, especially in older buildings where walls settle.

How to address it:
Reinforcing anchor points stabilizes the window and improves overall durability.

Incorrectly installed drainage channels cause water to accumulate inside the frame instead of draining outward.

How to address it:
Clearing or redesigning drainage paths prevents water buildup and frame deterioration.

Small installation-related flaws often go unnoticed until they lead to significant performance issues.

How to address it:
Early inspection and timely Réparation Fenêtres prevent installation defects from turning into major problems.
