A properly maintained timber door will last generations. A neglected one starts failing within 5-8 years. The schedule below isn't demanding — most items take under 10 minutes — but doing them consistently is what separates doors that last from doors that don't.
Wipe the door faces and frames with a damp cloth and mild soap solution. Avoid abrasive cleaners, harsh solvents and pressure washers — they damage microporous and oil finishes.
Pay attention to the bottom rail, threshold and any horizontal ledges where water and grit accumulate. These are the first parts of the door to suffer if neglected.
Check perimeter seals (compression strips, brush seals, drop seals) for compression set, tears or missing sections. Replace as needed — new seals are inexpensive and dramatically improve thermal performance.
Compression seals should feel springy under a fingernail. If they stay depressed, they're past their useful life.
Tighten hinge screws (top hinge takes most load), lock keep screws and any decorative hardware. A few millimetres of movement at hinge points causes most 'door dropping' complaints. Ten minutes with a screwdriver prevents years of accumulating problems.
Check lock operation — smooth cylinder, positive throw of bolts. Lubricate cylinders with graphite powder or dedicated lock lubricant (not oil, which attracts dirt).
Refresh exterior microporous finishes (paint, stain or oil). The earlier you re-coat, the lighter the prep work — a scuff-sand and single coat once every 5 years, versus a full strip-and-refinish every 15+ years if you let it go.
Signs it's time: colour fading, water no longer beading on the surface, visible cracking of the finish, hairline splits appearing in the timber.
Inspect the bottom rail and weather bar for impact damage and standing water. Bottom rails are the first thing to suffer in driven rain — a small crack or lifted finish is easy to address early but expensive if ignored for a season.
Also check gutters and downpipes above the door — a leaking gutter dumping water on a door head is a common cause of premature failure.
Book a workshop service: door removed, stripped, structural check, splicing of any deteriorating timber, ironmongery overhaul, refinish, rehang. Adds 20-30 years to the door's service life. Typically £600-£1,400 depending on door type and condition — vastly cheaper than replacement.
Following this schedule, a bespoke timber door will comfortably reach 30-50 years of service — often outlasting the owners. Museum examples of Georgian and Victorian doors still in service after 200+ years demonstrate what timber is capable of when maintained.
By comparison, UPVC and composite doors have manufacturer lifespans of 20-30 years and are usually beyond economic repair after that. Timber, properly cared for, is the only door material that can genuinely last a lifetime.
