Upgrade Your Original Sash Windows To Energy Efficient Windows

Our double glazing will radically improve your original windows and make them energy efficient and immediately save you money on your heating bills

For a home to be truly energy-efficient, it must have energy-efficient window solutions installed. Our double glaze upgrade service is designed to radically improve your original windows and make them energy efficient.

We offer the latest energy-efficient double glazing on the market today, at competitive prices. We can install your choice of double glazing into your original sash windows and fully restore the sash & case window. Your windows are then fully painted with a three-part exterior paint system. Our 3-part exterior gloss system offers high gloss protection with weathering durability that will last for many years of maintenance-free.

Our Upgrade Processes

Glazing:
Top and bottom sashes are removed. The glass is removed and rebate (edges) tidied up or routed out to take new glazing choice. The windows are fully inspected for any rotten wood and repaired as required. The rebate is primed. The new glazing units are fitted. Face putty finish externally on sashes. The windows are re-weighted to suit the new weight of window for ease of action.

Painting:
The sash case is fully inspected from sills, parting beads and pulley lining for any rotten wood and is repaired as required. Poor condition paint is removed and sanded down. Windows are filled where required. One coat of primer is applied to new or bare wood. One coat of undercoat is applied, followed by one or two coats of gloss.

Sand Mastic Finish:
Existing mastic is removed. An insulating foam is inserted around the case between the stone and wood. The window is then re-pointed with traditional sand mastic.

Draught Proofing:
The baton rods are removed. They are routed out to take the appropriate gauge of draught pile. The lower sash window is routed along mid and bottom rails and fitted with 12mm gauge draught pile. About our draught proofing >

Re-roping:
The working condition of existing sash rope is checked, and new sash rope can be fitted to the windows if required. Pulley wheels are inspected and can also be replaced if necessary.
