Windows, like any part of your home, experience wear and tear over time. A draughty window, a cracked pane, or a jammed sash can disrupt your comfort, security, and energy efficiency. But how do you know when it’s time for a simple repair or a complete window replacement?

At ASQB, we understand that making this decision can be tricky. That’s why we offer expert assessments to help you determine the best course of action. In some cases, minor repairs can restore your window’s functionality and aesthetics. However, if the damage is extensive or the window is outdated, a replacement may be the more cost-effective and energy-efficient option in the long run.

How do I get my windows repaired?

While some minor window repairs can be tackled as a DIY project, most common issues often require the expertise of a professional window technician. Attempting to fix complicated mechanisms or structural problems yourself can lead to further damage and even safety hazards.

Frequently Asked Questions

In most cases, home insurance will cover accidental damage to windows, such as breakage from a storm or fallen tree. However, it’s important to check your specific policy for exclusions or limitations.

The cost of window replacement depends on:

  • The number of windows being replaced.
  • The size and style of the windows.
  • The type of material used (e.g., aluminium, timber).
  • The type of glazing (e.g., single, double, or triple glazed).
  • The complexity of the installation.

In some cases, it’s possible to replace just the damaged part of a window, such as a broken pane or faulty hardware. However, if the damage is extensive or the window is old and inefficient, a full window replacement may be more cost-effective in the long run.

The cost of repairing a window is generally lower than replacing it. However, if the damage is significant or the window is old and inefficient, a replacement may be the better option in terms of long-term cost savings and improved energy efficiency.
