  • Are they difficult to open or close?
  • Do they let in draughts or unacceptable levels of noise?
  • Do they rattle?

If you answered YES to any of the above, we can HELP! Carry on reading.

Restoration and Repairs

We believe in carrying out an assessment to see if repairs can be made.

Restoration and repairs can very often be carried out rather than having to replace the window. This is an option worth considering as it's less expensive and can often prove as efficient as replacement. Many of the old Victorian and Georgian sashes were made using far superior quality timber than the timber used in modern day joinery so we encourage our customers to bear this in mind when thinking about sash window repairs vs. replacement.

Draught Proofing

Draughts are a common problem. The immediate solution in many people's minds are to have them replaced with overly expenisve double-glazing. Don't!

Draught proofing is more environmentally friendly than fitting new windows and can be installed for a fraction of the cost of complete replacement. There is also a huge misconception that the energy that you're losing through your windows is due to the fact that they're single glazed when in fact it is due to the cold air coming into your home through the gaps around your windows. More heat is lost in this way than can be saved by trying to double-glaze your existing windows. The cost of draught proofing can generally be recouped within 5 - 12 years. It can take up to 80 years* for new double glazed windows to start saving you money.

Our overhaul and sash window draught proofing service aims to stop these draughts and start saving you money.


Replacement maybe your only option if your existing sash windows have deteriorated beyond the point where they can be repaired, or if the sash windows that were once original to your house have at some point been removed and you may wish to re-instate them back to their former glory with exact replicas. We can help in both of these situations.
