How often should double glazed windows be resealed?

Taking care of your double glazed windows every now and then is really important to keep them working well and save you money.

You should probably reseal your windows every 10 to 15 years, but it depends on the weather and how well they were installed in the first place. Regular checks can help you spot issues early and keep everything running smoothly.

Here are some signs it’s time for resealing:

• Condensation between the panes: this usually means the seal has failed.
• Drafts or increased energy bills: if it feels colder around your windows or your heating costs are rising, the seals might be compromised.
• Visible damage or wear: cracks, gaps, or damaged weather stripping.

Keep a close eye on these signs, and regular inspections can help your windows stay in top shape for years to come! If you think your windows may need a bigger fix, we have a full guide on window replacement costs here.

FAQs common questions

What is double glazed reglazing, and when is it needed?

Reglazing involves replacing the glass pane or sealed unit in a window frame. It’s usually needed when the glass is cracked, broken, or the seals around double glazing have failed, causing condensation or energy loss.

Can all windows be reglazed, or are there limitations?

Most windows can be reglazed, especially if the frame is still in good condition. However, severely damaged or warped frames may require full window replacement instead of reglazing. See our new window cost guide here.

How long does the reglazing process take?

Reglazing a single window pane can be done within a few hours, but this depends on the type of window and the extent of work needed.

What are the risks of not reglazing damaged windows?

Failing to reglaze can lead to increased energy costs, condensation-related damage like mold, and reduced comfort and security in your home.
