How often should you reseal your windows?

You only need to reseal your windows when problems start to arise. As mentioned above, tell-tale signs that your window seals have broken is if they are draughty or if condensation on the internal pane of your window has formed. 

We suggest that you do periodical checks of your windows to see if they are performing effectively and spot any faults early.

How to reseal your windows

Usually, we recommend leaving the window seal replacement to the professionals, to ensure it is done properly, but if you’re a DIY whizz you may choose to reseal your windows yourself. 

Here’s a quick guide on how:

  • Step 1 – Remove window trims

The first thing that you will want to do is, using a hammer and a pry bar, remove the windows trim (internal and external if necessary). 

  • Step 2 – Apply the sealant 

You can now fill the void with window sealant, avoiding touching the sealant whilst it is wet. There are numerous different sealants available including silicone, latex and butyl rubber. 

  • Step 3 – Remove any excess 

After the sealant has fully dried, you can now use a knife to cut off any excess. 

  • Step 4 – Replace the trim 

Finally, you can now replace the trim, touching up any paint imperfections if necessary. 

Benefits of resealing your windows 

Below is a list of some of the benefits of ensuring that you check your windows for faulty seals and resealing your windows: 

  • Energy efficiency 

Resealing your windows will greatly increase their energy efficiency, helping to keep your home at more comfortable temperature. 

  • Prevents draughts 

If you feel draughts coming from your windows, then this is an indicator that your window seals need resealing. By doing this, you can form an airtight seal that prevents those pesky draughts. 

  • Tackles condensation 

Condensation can form on your windows where the air can pass through the gaps around your window. By resealing your windows, you can stop condensation in their tracks. Leaving condensation untreated can result in a colder house and can even lead to mould and damp forming.
