Compare Sash Window Quotes in Otford
Vertical sliding sashes are part of the character of many older houses in and around Otford, and many owners now want to restore them or reinstate them where they were lost. The job can be anything from new cords to a complete set of new timber windows.
Send a short description of the windows and Kent Windows will pass your enquiry to independent specialists covering Otford, Kent. If suitable firms have space in their diaries, as many as four could offer a survey and quote. It is free to ask and you are under no obligation.
Your Options for Sash Windows
Where the timber is mostly sound, an overhaul can give old sashes many more years: re-cording, localised repairs and draught seals make them run smoothly and cut draughts. For listed houses, secondary glazing inside the original sash is another option.
Where only the sashes are beyond repair, new ones can be hung in the existing boxes. Otherwise, the choice is between a complete new timber window and a uPVC vertical slider, with uPVC cheaper but usually heavier in appearance.
Signs Your Sashes Need Attention
- 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
If your house lost its sashes to casements, reinstating them can transform the frontage, though you should confirm the planning position before ordering.
A sash specialist should test both upper and lower sashes. Cords, weights, pulleys, draught seals and soft timber can then be priced separately from new glazing or a complete replacement.
From Survey to Finished Sashes
- Condition survey: every sash, box frame and cill is checked, with a recommendation for each window.
- Planning check: listed buildings and Article 4 areas may need approval before work begins.
- Manufacture: new sashes or boxes are made to measure, usually over several weeks.
- On site: overhauled sashes go back into their boxes on fresh cords, or new windows are fixed in, weighted and adjusted.
- Decoration: beads and linings are refitted, decoration completed if agreed and each sash tested.
Specialists usually work window by window so the house stays secure. Taller townhouses may need scaffolding for upper sashes.
Questions for the Survey Visit
Ask for a note on each window explaining what can be repaired and what cannot. Heavier double glazed sashes may need heavier weights or stronger balances, and there has to be room in the box for them to work.
Ask how the new sashes will match the glazing pattern and details of the old ones. 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.
What Do Sash Windows Cost?
The guide range for sash windows is £950–£16,500. The lower end covers one slider or one overhauled timber sash, while new double glazed timber boxes on every floor of a townhouse sits toward the top. Treat the range as a budget until your windows are surveyed.
Confirm in writing whether it includes VAT, access towers or scaffold, painting, splicing repairs and any plaster or lining work around the boxes.
Planning and Consents in Otford
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. Before ordering, speak to Sevenoaks District 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.

Sash Window Questions from Otford
How much do sash windows cost in Otford?
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 Otford?
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.
