Refurbish or replace your box sash windows?
In many cases, replacing older box sash windows entirely is more cost-effective than refurbishing them. New wooden box sash windows improve energy efficiency, security and reliability, while preserving the traditional appearance of your home and avoiding repeated repair costs over time.
If you’re unsure which option makes most sense for your property, we’re happy to assess your windows and provide honest advice.
