How to Stop Heat Escaping Through Old UPVC Windows This Autumn in St Helens

Oct 08, 2026

With colder weather settling in across St Helens, keeping your home warm and comfortable is becoming more important.


As temperatures continue to drop, many homeowners are turning up their heating. But have you noticed that some rooms still feel cold, even when the radiators are on?


Your windows could be part of the problem.


Old, damaged or poorly sealed UPVC windows can allow valuable heat to escape and cold draughts to enter your home. This can make your heating work harder and leave certain rooms feeling uncomfortable.


The good news is that there are several ways to improve your windows and reduce heat loss before winter arrives.


1. Check Your Windows for Draughts

One of the first signs that your windows need attention is a cold draught around the frame.


Over time, window seals can wear down, hinges can become loose, and frames may no longer close as tightly as they should.


Try running your hand around the edges of a closed window on a windy day. If you notice cold air coming through, it may be time to have your windows inspected.


Replacing worn seals or adjusting the hinges may solve the problem without needing a complete window replacement.



2. Inspect Your Double Glazing

Double glazing helps reduce heat loss by creating an insulating space between two panes of glass.


However, when the sealed unit fails, moisture can enter between the panes, causing misting or condensation inside the glass.


This can indicate that the window is no longer performing as intended.


A professional may be able to replace the failed glass unit while keeping the existing UPVC frame, depending on its condition.



3. Consider Energy-Efficient UPVC Windows

If your windows are old, damaged or no longer keeping your home comfortable, replacing them with modern energy-efficient UPVC windows could make a noticeable difference.


Modern UPVC windows can offer several benefits:

  • Improved thermal insulation.
  • Fewer cold draughts.
  • Better noise reduction.
  • Enhanced home security.
  • Reduced maintenance requirements.


Choosing windows with suitable energy ratings and professional installation can help keep your home warmer throughout the colder months.



4. Keep Your Curtains and Blinds Working for You

Small changes can also help reduce heat loss.


Close your curtains or blinds during colder evenings to provide an extra layer of insulation.


During the day, open them to allow natural sunlight to warm your rooms.


Make sure curtains do not cover radiators, as this can prevent warm air from circulating properly.



5. Arrange Window Repairs Before Winter

With winter getting closer, now is a good time to inspect your windows and address any problems before temperatures drop further.


Look for damaged seals, faulty handles, loose hinges and misted double glazing.
