To ensure the investment in sash windows lasts for years, a constant maintenance schedule is required.
Annual Inspection: Check for cracks in the paintwork, as wetness ingress is the primary reason for rot.Cleaning up the Tracks: Ensure the "pockets" and sills are without debris and dirt that can jam the system.Waxing the Sills: Applying a light coat of beeswax to the vertical stiles can help the sashes glide more efficiently.Checking the Cords: Inspect for tearing.
