Timber Bi-Fold Doors in Dorset
We make and fit Timber Bi-Fold Doors throughout Dorset — measured properly, built from timber chosen for the exposure, and adjusted once they are in.
6 of the 11 towns we cover in Dorset are coastal, where Accoya or dense hardwood and marine-grade stainless ironmongery are the sensible specification, and 6 carry designated conservation areas where the glazing pattern and mouldings need to match what is already there.
Most door problems are not the door. They are an opening that has moved, a cill that sheds water backwards, or a finish that was never cured properly. A survey is what separates a door that works from one you fight with.

Common questions
Can timber bi-folds run smoothly long term?
Yes, on a top-hung track with the weight carried by the head rather than the cill. It keeps the running gear out of the water and the panels aligned.
How often should a coastal door be recoated?
Three to five years on exposed elevations, against seven or more inland. Salt-facing elevations always go first.
What timber holds up best near the coast?
Accoya first, then dense hardwoods. Modified timber barely moves with humidity swings, which is exactly the load a coastal door is under.
What door suits a Victorian terrace?
A four-panel door with a bolection moulding and an etched or obscured upper light. Stile widths matter — narrow modern stiles make the proportions look wrong immediately.
What timber do you use?
Engineered redwood for painted doors, dense hardwoods such as sapele or idigbo where more strength is wanted, European oak where the grain is the point, and Accoya on exposed and coastal openings.
Can you match an existing door?
Yes. We take the mouldings, panel proportions and glazing pattern from the original and reproduce them. If the door is beyond saving we can still copy it before it goes.
