Enshrined in British design as a classic, once cutting-edge piece of engineering, sash windows are a staple of exterior (and interior) elegance and an important part of your home’s history. Changing the face of residential architecture for over 200 years, sash windows are a timeless choice and are now the top pick for those building their dream home from scratch. If you happen to live in an older property that has original sash windows in situ, you’ll likely want to preserve them for as long as you can.

However, is this something you should do yourself? Can you trust window firms to treat your historic sash windows with the care and attention that they deserve? We’ll answer these questions and more in this quick guide to repairing sash windows.

Can I repair the sash windows on my house myself?

In short, no. Unless you’re an experienced professional with sash window knowledge, we don’t recommend that you try to repair your sash windows yourself. Not only do they feature advanced engineering mechanisms, but original sash windows are a key part of history and therefore need to be handled in the right way.

By taking on the repair yourself, you might also be impeding your exit options in the case of a fire – it’s essential that you’re able to open your windows, particularly those on a ground floor level.

How can I tell if my sash windows need repairing?

Common signs that indicate a faulty sash window include:

  • Rattling
  • Decay/rot
  • Draughts
  • Sticking
  • Stiffness

In terms of both maintaining character and living sustainably, choosing to repair the original sash windows is a much better option than replacing them, with experts usually able to repair all of the above issues. Where you do choose to replace your sash windows, ensure that you opt for a reputable, bespoke service to ensure that they remain as attractive and sympathetic as the originals.

How can I tell if my sash windows are beyond repair?
