Timber Windows
We make every window in our Mortehoe workshop. Hand-cut joinery, factory-applied paint or stain, glazed with double or triple units to current Building Regulations U-values. Installed by our own carpenters.
A properly made timber window is a fifty-year piece of joinery. With minimal maintenance (a repaint every eight to ten years), it will outlast three or four cycles of uPVC, look better at every stage, and be repairable for its entire life rather than disposable at the end.
Homeowners replacing tired uPVC, refurbishing period properties, or specifying new joinery on new builds and extensions, wanting properly made timber windows that will last.

What we use
European Oak
The prestige choice for stained or oiled finishes. Naturally durable (Class 2), hard and dense, develops a silver patina if left untreated.
Accoya
Modified radiata pine, 50-year above-ground warranty, exceptional dimensional stability, takes paint better than any other timber we use. Our default for painted windows.
Red Grandis
FSC-certified plantation eucalyptus, fine-grained, very stable, accepts paint cleanly. Excellent value-engineered alternative to Accoya for sheltered elevations.
Softwoods
Scots pine and Douglas fir for tighter budgets or specific aesthetic. Need more frequent repainting and careful site detailing to perform well.
Typical pricing
From £900 per unit
Subject to specification and site conditions.

What we don’t do
We do not sell uPVC. There are excellent uPVC window companies; we know which to recommend if uPVC is the right choice. Our work serves a different purpose.
Things people ask us
Which timber should I choose?
European oak is the most prestigious and longest-lived if you want a stained finish that shows the grain. Accoya is the technical best, modified softwood with 50-year above-ground durability, dimensionally stable, takes paint beautifully. Red Grandis is the value choice for a painted finish, FSC-certified and stable. Scots pine and Douglas fir are options on tight budgets but need more maintenance.
Paint or stain, which finish lasts longer?
Modern microporous paint systems on Accoya or Red Grandis last 8-10 years between repaints. Translucent stains on oak typically need refreshing at 5-7 years. Both are factory-applied in our workshop with 3-4 coats before delivery, far better than anything applied on site.
What U-values do you achieve?
Double glazed thermal-break units come in at around 1.4 W/m²K through the whole window. Triple glazed reaches 0.8 W/m²K. Both comfortably meet current Building Regs (1.6 W/m²K for replacement windows in existing buildings).
What glazing options are available?
Argon-filled double or triple glazing as standard. Solar control coatings for south-facing elevations, acoustic glass for noisy locations, Pilkington Activ self-cleaning, obscure glass for bathrooms, leaded or astragal-bar details for traditional designs.
How secure are timber windows?
Multi-point locking espagnolette systems as standard, BS3621 compliant hardware available on all opening sashes. Hinge restrictors for child safety, key-locking handles where required by insurance. A properly specified timber casement is at least as secure as an equivalent uPVC unit.
What maintenance do they need?
An annual wipe-down and a check of seals and hardware. Repaint or re-stain every 8-10 years on coastal or exposed elevations, 10-12 years on sheltered ones. Any failed pane can be replaced individually; any rotted section can be cut out and a new piece spliced in, repairable for life.
How long does installation take?
A typical 8-window house takes 3-4 days to install, working room by room so the house stays weather-tight overnight. Larger jobs and full new-build glazing schedules are programmed within the wider build.
What are current lead times?
Allow 8-12 weeks from sign-off of final drawings to delivery, plus installation week. The current figure in the panel above is updated as our workshop fills.
