By picking to restore these systems, house owners are often keeping a higher quality of material than what can be discovered on the marketplace today.
The Benefits of Expert Renovation

- Glazing and Putty: Cracked panes are changed, and old, breakable putty is removed and reapplied to guarantee a watertight seal.
- Re-weighting and Re-cording: The sash cables are changed with premium waxed cotton or nylon-core cables. The weights are checked and "balanced" to guarantee the window opens and stays open easily.
- Draught Proofing: This is an important modern-day upgrade. Discreet brush strips are machined into the wood beads and meeting rails to get rid of rattles and cold air ingress.
