How Often Should You Service Your Door?

Short answer
Most composite doors benefit from a light clean every few weeks and a more thorough annual service that includes lubricating hinges and locks with light machine oil, checking the door closes and locks smoothly, and inspecting seals. Coastal properties should rinse salt deposits monthly and may need lubrication twice a year.
Composite doors don't need frequent attention, but a small annual routine keeps everything working as it should and helps you catch minor issues before they become bigger ones. Here's a realistic schedule for most Cornwall homes.
Every few weeks
A quick wipe-down with mild soapy water and a soft cloth keeps grime, pollen and traffic dirt from building up on the door surface and glass. This takes a few minutes and is the single most useful habit for keeping the finish looking good long-term.
Monthly, if you're near the coast
Properties within around a mile of the sea should rinse the door down with clean water monthly to remove salt deposits, which can otherwise sit on the surface and hardware. See our dedicated coastal care guide for more detail on this.

Once a year: the full service
Once a year, go over the whole door: apply light machine oil sparingly to hinges and the multi-point lock's moving parts, check the door closes squarely and locks smoothly, wipe down handles and letterplates, and give the glass a proper clean.
- Lubricate hinges and lock mechanism
- Check door closes and locks smoothly
- Clean handles, letterplate and glass
- Look for any new marks, gaps or draughts
Seasonal watch-points
Cold, damp winters are when stiffness in locks and hinges tends to show up most, so an autumn lubrication before the weather turns is well timed. Summer heat can highlight any sealant or frame movement, worth a quick visual check when you're cleaning.
When routine care isn't enough
If your annual check turns up something more than light stiffness — a lock that won't engage, a handle with noticeable play, or draughts you can feel — that's a job for a professional rather than something to keep working around.
Frequently asked questions
Do I need a professional to service my door every year?
Not necessarily for basic cleaning and lubrication, which most homeowners can manage themselves. But if you notice any mechanical issue during your check, or simply want peace of mind, a professional service visit covers everything thoroughly.
What's included in a professional door service?
A professional visit typically covers lubricating and adjusting hinges and locks, checking alignment and seals, and identifying any developing issues before they worsen. It's a sensible option if your door sees heavy daily use or you haven't serviced it in a while.
Can neglecting servicing cause permanent damage?
Leaving a stiff lock or hinge unattended for a long period can lead to more significant wear or a mechanism seizing, which then needs professional repair rather than simple lubrication. Regular light care avoids this.
Is servicing different for older composite doors?
Older doors that have seen years of use may benefit from a professional check even if nothing seems obviously wrong, since components naturally wear over a longer period. It's a good way to extend the door's working life.
