Accoya Windows in Sherborne
Accoya is acetylated timber — dimensionally stable, rot-resistant and warranted for 50 years above ground. The best-performing paint substrate available.
Homeowners across Sherborne come to us for accoya windows after a uPVC replacement has aged badly. Timber is the material you specify when you intend to still be happy with it in twenty years.
What is included
- Glazing beaded internally, so the sealed units can be replaced without disturbing the external finish.
- Kiln-dried to 12% moisture content before machining, so the sections stay true once they are installed.
- Stainless or solid brass ironmongery, because plated steel fails first and takes the finish with it.
- Glazing beaded internally, so the sealed units can be replaced without disturbing the external finish.
Timber moves. The craft in accoya windows is anticipating exactly how much, in Sherborne conditions, and detailing the joints and finish so that movement never becomes a problem.

Do you work on listed buildings?
Regularly. Listed building consent turns on detail — sightlines, glazing bar sections, opening method and glass type. We survey the existing joinery, record the profiles and produce drawings you can submit. We will not quote a detail we know will not pass.
How much maintenance do they need?
Far less than people expect. Wash the frames twice a year, inspect the finish annually, and expect to recoat exposed elevations every eight to ten years. Sheltered elevations often go considerably longer. Modern micro-porous coatings are a different product entirely from the gloss paints that gave timber its reputation.
Which hardwood should I choose?
It depends on the finish. For painted work, Idigbo and Accoya are excellent — stable, even-grained and superb paint substrates. For a stained or oiled finish where the grain is meant to show, European oak and Sapele are the usual choices. We will recommend a species at survey based on your finish and exposure.
What is Accoya and is it worth the premium?
Accoya is timber that has been acetylated — chemically modified so it no longer absorbs water. It barely moves, does not rot, and carries a 50-year above-ground warranty. It is the single best paint substrate available. For exposed elevations and coastal sites the premium usually pays for itself.
