Timber Window Replacement
Where the existing joinery is beyond economic repair, we replace like-for-like in hardwood — usually reusing the original opening.
the UK has a housing stock that punishes off-the-shelf joinery — openings settle, reveals go out of square, and cills rarely sit level. Bespoke timber window replacement solve that properly.
What you get with our timber window replacement
- Engineered laminated sections on anything over 1.2m, which resist bowing far better than solid stock.
- End-grain sealed at every cut before assembly — the single detail that decides whether joinery rots.
- Glazing beaded internally, so the sealed units can be replaced without disturbing the external finish.
- FSC-certified hardwood with documented chain of custody, available on request for planning submissions.
- Engineered laminated sections on anything over 1.2m, which resist bowing far better than solid stock.
How we price timber window replacement
The guide range above assumes a typical domestic unit in Idigbo with argon-filled double glazing and a factory-painted finish. The variables that move the number most are, in order: overall size, timber species, glazing specification and finish. Access and making good come next.
| Variable | Effect on price |
|---|---|
| Timber species | Idigbo baseline · Sapele +7% · Accoya +24% · European oak +38% |
| Glazing | Double baseline · heritage slim +13% · triple +19% |
| Finish | Primed only −8% · factory painted baseline · stained or oiled +4% |
| Quantity | 2–4 units −3% · 5–9 units −6% · 10+ units −10% |
We install across your county with our own fitting teams and make good internally as part of the price. No sub-contracted surprises.

Replacement — measured, priced and drawn before anything is made.
Not sure on budget?
The guide price tool gives you a realistic range for timber window replacement in under two minutes.
Get an indicative priceAre timber windows warm enough for Building Regulations?
Yes, comfortably. Timber is a natural insulator with far lower conductivity than aluminium or steel. A standard hardwood double-glazed window achieves around 1.2–1.4 W/m²K whole-window, against a 1.4 requirement for replacements. Triple glazing in a deeper section will reach roughly 0.8.
Can I have double glazing in a conservation area?
Usually, yes — using slim-profile sealed units as narrow as 11mm, which fit within traditional glazing bar sections without fattening them. Conservation officers vary, so we specify from the outset to whatever the local authority has stated and provide section drawings for the application.
Do you repair windows or only replace them?
We repair wherever repair is the right answer. Rot is normally localised in a cill or the bottom of a stile, and splicing in new hardwood is typically a third of the cost of replacement. We will tell you honestly at survey which way the economics fall.
Can you match existing windows?
Yes. That is most of what we do. We record the existing sections at survey, reproduce the mouldings and sightlines, and match the finish. On listed buildings we will produce like-for-like profile drawings for the consent application.
Are hardwood windows secure?
Yes. Multi-point locking, laminated glass options and key-locking handles are all available, and a solid hardwood frame is considerably harder to attack than a hollow plastic one. We can specify to PAS 24 where a planning condition or insurer requires it.
Do you take away the old windows?
Yes. Removal and responsible disposal are included, along with making good internally. We work one opening at a time so the property is never left open, and we clear the site each day.
