Once professionally draught-proofed, rebalanced and re-corded, your sash windows will operate smoothly, with less rattles and significantly reduced draughts, providing you with many years of comfortable operation.
Current government legislation allows us to charge lower rate VAT on our draught reduction services. Combined with the energy savings over the years that draught free windows can provide (see the Facts & Figures below) this can be a cost-effective investment.
- Careful dismantling of the sash window
- Weighing the sashes and checking the weights correctly counterbalance
- Routing in brush strips to the meeting rails
- Checking, cleaning and lubricating the pulleys
- Re-cording the window with new cotton sash cord and correct weights
- Renewing parting and staff beads with weatherpile carriers and brush strips
- Removing excess paint obstructing sash running surfaces

Historic England❐ Historic England suggest that servicing a window and applying a draught reduction system will reduce draughts by as much as 80% to 85%.
To quantify this we asked the Energy Saving Trust❐
Energy Saving Trust (
what this equated to in terms of cash savings and C )O2 emissions. They provided the following response:
"The average financial benefit from draught proofing all the single-glazed sash windows in a typical house is £45 per year. This equates to around 630 kWh and 120 kg of CO2 saved over the course of a year."
– Energy Saving Trust, 2010.
In terms of today's fuel prices, a 630 kWh energy saving amounts to around £97 per year off your electricity bill, or £23 per year off your gas bill (with dual-fuel savings somewhere in-between.)
Calculations based on the average unit-price per kWh for electricity and gas (inc. VAT) in the South West of England. According to Government domestic energy price statistics❐ for 2017.
Historic England also suggest that a close fitting set of blinds, thick lined
curtains and shutters will further reduce heat loss by as much as 30% through
