Benefits of Repairing Sash Windows

Repairing existing windows is often more cost-effective and suitable for heritage properties.

  • Maintains original character
  • Improves insulation and reduces draughts
  • Extends window lifespan
  • More affordable than full replacement

When to Repair vs Replace

If frames are structurally sound, repairs are usually the best option. However, if windows are beyond repair, we may recommend upgrading to double glazed sash windows for improved performance.
