Restoration vs. Replacement: Making the Right Choice
A respectable sliding sash window business will usually use 2 pathways: restoration of existing frames or complete replacement.
The Restoration Process
If the initial timber is structurally sound, restoration is typically the chosen route, especially for Grade II listed structures. This process involves:
- Dismantling: Removing the sashes from the box frame.
- Repairing: Cutting out areas of “damp rot” and changing them with seasoned wood.
- Draught-Proofing: Installing modern-day brush stacks into the meeting rails and beads to get rid of rattles and cold areas.

Specialist business make “bespoke” joinery, guaranteeing the new windows are millimetre-perfect replicas of the originals.
Enhancing Energy Efficiency
Historically, sash windows were notorious for being draughty and thermally ineffective. Nevertheless, modern-day engineering has transformed their efficiency. An expert company focuses on several key locations to improve energy scores:
- Vacuum Glazing: An innovation where a microscopic gap in between 2 panes of glass offers the insulation of triple glazing with the thickness of a single pane. This is perfect for heritage residential or commercial properties where thin frames are compulsory.
- Low-E Glass: Coated glass that reflects heat back into the space.
- Inert Gas Fillings: Using Argon or Krypton gas in between panes to minimize thermal transfer.
Maintenance Tips for Longevity
To make sure the financial investment in sash windows lasts for years, a constant upkeep schedule is needed.
- Yearly Inspection: Check for fractures in the paintwork, as wetness ingress is the main reason for rot.
- Cleaning up the Tracks: Ensure the “pockets” and sills are totally free of debris and dirt that can jam the system.

Often Asked Questions (FAQ)
1. Are sliding sash windows more costly than casement windows?
