Hardwood Bay Windows in Helston
Bay windows carry load, so they are made as a single engineered unit with proper corner posts and structural head — not bolted-together casements.
Every hardwood bay windows we make in Helston starts the same way: a surveyor measures the actual opening, records the existing profiles and checks how the reveal sits. Nothing is ordered from a catalogue.
What is included
- Factory-finished in controlled conditions — three coats minimum, fully cured before delivery.
- End-grain sealed at every cut before assembly — the single detail that decides whether joinery rots.
- Micro-porous finishes that let the timber breathe rather than trapping moisture behind a hard film.
- Factory-finished in controlled conditions — three coats minimum, fully cured before delivery.
Choosing bay windows for a property in Helston is mostly a question of substrate and detail. Get the timber and the sections right and the finish looks after itself for decades.
We install across Cornwall with our own fitting teams and make good internally as part of the price. No sub-contracted surprises.

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.
Are 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.
