Conservation Area Windows
Slim double glazing, correct sightlines and traditional ironmongery — specified from the outset to pass conservation area scrutiny.
The case for conservation area windows in the UK is straightforward — hardwood outlasts the alternatives, can be repaired rather than replaced, and holds the character of the building.
What you get with our conservation area windows
- Weathered cills with a proper drip groove, so water leaves the timber instead of tracking back under it.
- Micro-porous finishes that let the timber breathe rather than trapping moisture behind a hard film.
- Kiln-dried to 12% moisture content before machining, so the sections stay true once they are installed.
- Warm-edge spacer bars as standard, which cut the cold bridge at the glass edge and reduce condensation.
- Weathered cills with a proper drip groove, so water leaves the timber instead of tracking back under it.
How we price conservation area windows
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% |
Everything is made to order, so the quotation stage matters. We would rather spend an extra hour on the survey than get a section wrong.

Conservation Windows — measured, priced and drawn before anything is made.
Not sure on budget?
The guide price tool gives you a realistic range for conservation area windows in under two minutes.
Get an indicative priceDo 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.
How much disruption should I expect?
Less than most people fear. A straightforward replacement is one opening at a time, typically two to four windows a day. Scaffolding is only needed on higher elevations. We protect floors and furniture and leave the site clean each evening.
How long do hardwood windows actually last?
Properly specified and maintained hardwood joinery has a realistic service life of 60 years or more. The timber is rarely what fails — it is the finish and the seals, and both are renewable. That is the fundamental advantage over uPVC, where a failed unit or a distorted frame means the whole window goes.
