It is often more budget-friendly to replace a glass pane instead of installing an entire new window. The average supply and installation cost for window glass replacement is £100. A new double-glazed casement window installation costs between £300 - £800.

Here are some average costs to consider when replacing a window:

• Single pane installation – £27.50
• Old window removal – £20 - £30
• Window fitter hourly rate – £25 - £35

Glass replacement is likely the best option if you're happy with your window’s overall performance and only the glazing has been damaged.

If you are dealing with any of the following issues, it is often more cost-effective in the long term to replace the whole window installation:

• Mould growth around the window / on the frames – Switching to more energy-efficient windows can keep your home warm and dry. Old frames are often unable to provide reliable protection against damp and heat loss
• Difficulty opening and closing – Wood rot, wear and tear and swelling frames can cause window functionality issues. You may be able to perform temporary DIY fixes, but often, a full window replacement will be needed
• Poor soundproofing – Improve your home’s soundproofing by replacing single-glazed windows with high-quality double glazing or triple glazing

It's possible. Depending on the damage, fixing a broken window without replacing it may be possible. Common temporary window fixes include:

• Boarding over the window with plywood
• Removing loose shards of glass / covering exposed glass with thick packing tape
• Applying glass adhesive or masking tape to cracked glass

Always wear gloves when dealing with broken glass. It is also important to keep children and pets away from a shattered window. To stay safe, we recommend hiring a professional to replace the broken glass and permanently fix the problem.
