Guide to Resealing Windows

Window seals expand and contract over time due to temperature changes, and this may eventually wear them out. However, it can sometimes be difficult to tell exactly when a window seal should be replaced or repaired – in this guide, we cover how to spot the signs of window seal deterioration, and will take you through how to reseal windows and why it’s so important for your property.

How to find out if your windows need resealing

A simple visual inspection can help establish if a window needs resealing, or perhaps just repairing. Cast an eye over the areas where the windows meet the frame, where the window frame meets the wall, and where different sections of windows meet each other. Notice whether there are any telltale signs of wear and tear, or gaps and cracks in the seal.

Another pointer is a draught coming from your window area, or signs of condensation on internal panels of the glass panes.

How to reseal windows

It’s essential that window seal replacement should be done by a professional. If you fancy yourself as a DIY boffin, you may wish to attempt a window reseal yourself – but caution must be advised. Should you improperly seal the window, this could cause further issues down the line and may allow heat to escape your home. Call a professional, who will assess the severity of the window seal degradation and will suggest next steps.

Still experiencing issues? If resealing hasn’t done the trick, a complete window replacement may be required for a long-term solution.

How often should you reseal windows

The short answer is that windows should be resealed as and when you spot problems arising; the best thing you can do is periodically check their quality to spot issues early.  However, it is also thought that replacing the seal every 5 years will keep them fresh and functional, preventing problems further down the line.

What are the benefits of resealing windows?  

Window seal repair and replacement will enhance the energy efficiency of your windows, and therefore, your home. Draughts will be stopped in their tracks and warm air will instead be contained within the house instead of escaping through faulty seals. Boosting the energy efficiency of your windows will in turn lower your home energy bills, relieving the pressure from your bank balance – and the planet. Resealing will also help eliminate condensation which, if left untreated, can make a room feel colder.
