Sash Window Overhaul and Replacement in Herne Bay
Georgian, Regency and Victorian houses around Herne Bay were very often built with sliding sashes, and owners increasingly want to keep them working or put them back. Sash work ranges from a simple re-cord to full replacement of every box frame.
Tell us about your sash windows and Kent Windows will pass your enquiry to independent specialists covering Herne Bay, Kent. Depending on local availability, up to four firms may be in touch to measure up and price the work. It is free to ask and you are under no obligation.
Choosing the Right Approach
Sound original sashes can usually be overhauled rather than replaced: new cords, spliced timber repairs and brush draught-proofing stop the rattles and keep the original glass. On listed buildings, discreet secondary glazing can improve warmth without touching the sashes.
If the sashes have failed but the boxes are sound, new double glazed sashes can be made to fit. A full timber replacement or a uPVC slider are the remaining options, with uPVC cheaper but usually heavier in appearance.
When to Call a Sash Specialist
- A broken cord leaving a sash dropped or propped open
- Draughts and rattles at the meeting rails and beads
- Rotten cills and bottom rails, often worst on exposed elevations
- Sashes painted or swollen shut
- uPVC sliders whose balances no longer hold the sash up
Swapping unsympathetic casements back to sashes is a popular way to restore a period house, but check the planning position first.
During the survey, ask for the box frame and both sliding sashes to be checked. Cords, weights, pulleys, draught seals and soft timber can then be priced separately from new glazing or a complete replacement.
How Sash Work Is Done
- Inspection: every sash, box frame and cill is checked, with a recommendation for each window.
- Permissions: listed buildings and Article 4 areas may need approval before work begins.
- Joinery: new sashes or boxes are made to measure, usually over several weeks.
- Fitting: overhauled sashes go back into their boxes on fresh cords, or new windows are fixed in, weighted and adjusted.
- Final checks: beads and linings are refitted, decoration completed if agreed and each sash tested.
Overhauls are often done a window at a time, with the opening boarded while the sashes are in the workshop. Ask whether upstairs sashes need a scaffold or tower and whether it is included.
What the Quote Should Cover
A good sash survey separates sound timber from failed timber, window by window. Heavier double glazed sashes may need heavier weights or stronger balances, and there has to be room in the box for them to work.
Check that the horns, mouldings and pane pattern will match the originals. Agree the extent of painting, how any original glass or internal shutters will be protected, and ask for each sash to be demonstrated at handover.
Budgeting for Sash Windows
The guide range for sash windows is £950–£16,500. One uPVC vertical slider or a single sash overhaul sits near the bottom, while a complete set of new timber sash windows sits toward the top. Bespoke and listed-building work can exceed the range.
Ask whether each price includes VAT, access towers or scaffold, painting, splicing repairs and any plaster or lining work around the boxes.
Listed Buildings and Conservation Areas
On a house that is not listed, swapping worn sashes for new sashes of matching design rarely needs planning permission. Changing timber to uPVC, or sashes to casements, may need planning permission in a conservation area with an Article 4 direction, and any change to a listed building's windows usually needs listed building consent. For advice on your address, contact Canterbury City Council.
A brand-new sash window counts as controlled work, which a scheme-registered installer can certify for you. Re-cording, splicing and draught-proofing existing sashes count as repair, so no certificate is involved. Historic England's traditional windows guidance is useful background for period homes.

Common Questions About Sash Windows
How much do sash windows cost in Herne Bay?
The guide range is £950–£16,500, from one uPVC slider or a single sash overhaul to a whole house of double glazed timber sashes.
Should I overhaul or replace my old sash windows?
If most of the timber is sound, an overhaul is usually cheaper and keeps the original character. Replacement makes sense where rot is widespread.
Do I need permission to replace sash windows in Herne Bay?
Not usually on an unlisted house if the new windows look the same. Listed buildings need consent, and Article 4 conservation areas may restrict changes of material or style.
Can I get double glazed timber sash windows?
Yes. New timber sashes can take slim double glazed units, with heavier weights or balances. On listed buildings the council decides whether this is acceptable.
