Overview
Sash window restoration is sold to heritage properties, and the draught seal is the line that sells the warm house
Sash window restoration is the heritage end of the joinery trade. The customer owns a Georgian, Victorian, or Edwardian property where the original timber sash windows have been hanging on for a century: dropped sashes, weights detached from the cords, painted shut, draughty, single-glazed, and an ongoing source of complaints from the partner who's cold every winter. Replacement with UPVC is sometimes prohibited by planning rules, and is almost always the wrong call aesthetically. Restoration brings the original windows back to operating condition with draught seals, often a discreet slim-line double glazing, and a refurbished frame that looks original. A flat 'sash window refurbished, $1,400' quote that doesn't show the draught sealing and the glass option misses the conversation about warmth.
QuoteGenio gives sash window restorers a quoting shape that fits heritage work. Survey and condition report as the first line per window, sash re-build (new cords, weights re-located, sash repair) by sash, frame repair and stripping, draught sealing system as a named line (where the customer wants the warm-house upgrade), glazing options (single, slim double, vacuum), repainting, and any planning or listed-building compliance checks. Send via WhatsApp or email to the homeowner, take a deposit at booking, raise a progress invoice per window restored, and the final invoice closes with the heritage-appropriate finish and a draught-sealed window that opens cleanly.
Who it is for
Who uses QuoteGenio
Built for every kind of sash window restoration business, from solo cord-and-weight specialists to small heritage joinery teams.
The problem
The quoting headaches every sash window restorer knows
Sash work is window-by-window detail work. Without a clear proposal that lists each window with its scope, condition, and finish, customers get a flat fee that does not reflect the variation in joinery condition between windows.
Joinery condition variation
Window 1 needs cord and brushes; window 5 has rotten meeting rails and broken sash horns. Without per-window line items, the variation absorbs into a flat house price.
Verbal heritage spec
Listed-building consents need linseed-oil paint, lead-light glazing, and traditional cord. Customers expect the spec on the proposal in writing.
Slim double-glazing missed
Heritage-grade slim double-glazing is the highest-margin upgrade on a restoration. Without an upsell line, customers default to single-glazed.
The fix

Pricing guide
Typical Sash Window Restorers job pricing
A rough guide to what sash window restorers charge for common work. Pricing varies by window size, joinery condition, glazing type (single, slim double-glazing, lead-light), and listing grade. Listed-building work and full restoration with slim double-glazing sit at the top of these ranges.
| Job | Typical range |
|---|---|
| Cord and weight replacement (per sash) | $ 145 - $ 380 / sash |
| Brush draught-proofing (per window) | $ 220 - $ 480 / window |
| Joinery repair (rotten cill, meeting rails) | $ 280 - $ 950 / window |
| Slim double-glazing upgrade (per window) | $ 480 - $ 1,400 / window |
| Full restoration (per window, all of above) | $ 850 - $ 2,800 / window |
| Linseed oil paint finish (per window, traditional) | $ 145 - $ 380 / window |
| Lead-light replacement (per window, where applicable) | $ 280 - $ 850 / window |
Pricing shown in USD as a rough benchmark. Rates vary significantly by country, region, currency, and market.
Call-out fees
Always quote each window separately. Window 1 may need just cord and brushes ($ 380); window 5 may need full joinery and slim double-glazing ($ 2,400). A flat 'per house' fee absorbs the variation and customers respect itemised quotes more on heritage work.
Hourly vs fixed pricing
Use per-window fixed pricing for standard scopes (cord refresh, draught-proofing, full restoration). Use hourly pricing for unusual or unknown-scope joinery repairs. Always state the heritage spec on listed work (linseed oil, traditional cord, lead-light).

Common quoting mistakes
We talk to a lot of sash window restorers. The same per-window, listed-spec, and slim-double-glazing mistakes come up restoration after restoration. Fix these and your heritage rate will reflect the joinery work involved.
Mistake: Flat per-house fee
Better: Quote each window as its own line with scope and condition stated. Customers respect itemised quotes more on heritage work.
Mistake: Verbal slim double-glazing upgrade
Better: Quote slim double-glazing as a separate per-window upgrade line. It is the highest-margin upsell on restoration work.
Mistake: No listed-building spec
Better: State the heritage spec on every line on listed work (linseed oil paint, traditional cord, lead-light glazing). Conservation officers check, and customers expect it in writing.
Mistake: Joinery repair absorbed
Better: Quote rotten cill, meeting rail, sash horn, and other joinery repairs as separate per-window lines. Each window has different damage and itemising protects margin.
Mistake: No deposit on multi-window
Better: Take 30 to 50 percent deposit on multi-window restorations because joinery and glazing are made to spec.
Mistake: Verbal warranty terms
Better: State the workmanship warranty (typically 5 years on cord/draught-proofing, 10 years on slim double-glazing manufacturer) on the proposal.
Mistake: No expiry on the quote
Better: Set a 30 day validity. Heritage joinery and slim double-glazing pricing move with timber and glazing supply. State the validity.
Mistake: No follow-up after sending the quote
Better: Most quotes that don't close, don't close because nobody followed up. Send a polite check-in 48 hours after the quote lands, and a second nudge at day 7. Two of every three accepted quotes get there because someone followed up.
Step by step
How to quote sash window restoration
Always survey each window before quoting. A 30 to 60 minute survey tells you the count, the joinery condition (cord, brushes, sash horns, meeting rails, cills), the existing glazing (single, lead-light, original), the access (scaffolding required on second floor and above), and the listing grade if applicable. Quote per window based on what you saw rather than guessing from a phone description.
Itemise each window with its specific scope: cord and brushes, joinery repairs, slim double-glazing upgrade, paint finish. State the heritage spec on listed work (linseed oil, traditional cord, lead-light). Add scaffolding as a separate line on tall properties. Quote slim double-glazing as a per-window upgrade line because it is the highest-margin upsell.
Take a deposit on multi-window restorations. Single-window cord refresh usually invoices on completion. Multi-window restoration with slim double-glazing needs 30 to 50 percent deposit because joinery and glazing are made to spec and non-refundable. State the deposit clearly on the proposal.
Send via WhatsApp from the property. Heritage customers usually compare 2 to 3 specialists. The first detailed proposal with each window itemised and listed-building spec stated usually wins. Share via WhatsApp link, follow up after 48 hours, and once accepted invoice the deposit and order joinery.
