Step 3: Re-cording and Balancing

Old cords are replaced with modern-day, wax-coated cotton cables with a polyester core for additional strength. The weights are checked to ensure they completely counter-balance the weight of the sashes (particularly crucial if new, thicker glass has been installed).

Step 4: Draught-Proofing

A modern-day draught-proofing system is usually incorporated throughout the repair work. This includes machining small grooves into the beads and sashes to house brush strips. These strips close the gaps, eliminating rattles and significantly lowering heat loss.

Step 5: Glass and Putty Work

Among the most relentless misconceptions is that sash windows must be changed to make a home "warm." In reality, a restored and draught-proofed sash window can equal the thermal efficiency of lots of contemporary windows.

• Examine the Cills: Inspect the bottom of the window after heavy rain to guarantee water is draining away and not pooling.

Can rotten sash windows really be saved?
