Sash window replacement cost – how to reduce your bill
There are steps you can take to reduce your costs when replacing or upgrading sash windows. Some may be more or less practical for you depending on your personal circumstances and budget. Here are some ideas:
- Replace the sash, not the sash window. Often, the box frame is still in good condition so it is possible to replace the sashes within it, costing you less.
- Get a proper consultation from a professional company. The more thorough the consultation, the more likely it is that your windows will live up to your expectations, so there won’t be any additional costs.
- Draught proof and repair your sash windows. If your windows are generally in good condition, you could save a lot of money by draught proofing and repairing them instead of replacing them.
The only way to find out exactly how much new sash windows will cost is to get a bespoke quote. It’s completely free of charge and no obligation – so there’s no reason not to!
