Timber Bi-Fold Doors in Gwynedd
Timber Bi-Fold Doors made to measure for homes across Gwynedd, surveyed on site and finished in the workshop before they are hung.
6 of the 8 towns we cover in Gwynedd are coastal, where Accoya or dense hardwood and marine-grade stainless ironmongery are the sensible specification, and 1 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.
Does sea air really affect a timber door?
Yes, in two ways. Salt is hygroscopic so it holds moisture against the surface, and airborne chloride corrodes standard ironmongery quickly. Both are solvable at specification stage.
Which ironmongery survives salt air?
Grade A4 (marine) stainless steel. Standard A2 stainless and lacquered brass both fail within a few years within about a mile of open water.
What door suits a stone cottage?
A ledged, braced and boarded door with long strap hinges. Openings are usually low and rarely square, so the door is made to the opening as found.
Can you replace the frame as well as the door?
Yes, and often it is the better answer. A new leaf in a rotten frame will not seal properly however well the door itself is made.
Is timber a sustainable choice?
Responsibly sourced timber is the only mainstream door material that stores carbon rather than emitting it in manufacture, and a timber door can be repaired rather than replaced.
