Timber Bi-Fold Doors in Bangor
Homes in Bangor get Timber Bi-Fold Doors built around the opening they have, with the timber and finish specified against local conditions.
Specifying a door for Bangor
Bangor sits on the coast, so doors here deal with salt-laden air as well as rain. Salt is hygroscopic — it holds moisture against the surface long after the weather has passed — which is why standard softwood and standard ironmongery both fail early within about a mile of open water.
Housing in and around Bangor is largely stone and rendered cottage stock, which suits ledged, braced and boarded doors with a plank face and long strap hinges. We match the mouldings and panel proportions to what is already on the street rather than fitting a generic pattern.

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.
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.
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.
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.
How energy efficient is a timber door?
A modern insulated timber door with a sealed unit performs comparably to composite alternatives, and timber itself is a far poorer conductor than aluminium or steel.
What finish options are there?
Factory spray in any RAL or heritage colour, translucent stains, and natural oils on oak. All applied and cured in controlled conditions before the door ships.
