Timber Joinery Care and Maintenance Guide
Practical advice to help your timber joinery perform beautifully for years to come
Quality timber joinery is designed to provide decades of reliable performance.
Like any natural building material, timber responds to its environment and benefits from regular care. A simple maintenance routine, combined with the right storage and handling before installation, will help protect its appearance, maintain its performance and maximise its service life.
This guide outlines the key steps for caring for your timber joinery before installation and throughout its lifetime.
Before Installation
Correct storage is one of the most important factors in protecting timber joinery before it is installed.
As soon as your joinery arrives on site, it should be stored:
In a clean, dry and well-ventilated area.
Away from direct sunlight and weather.
Off the ground on a flat, level surface.
Fully supported to prevent twisting or distortion.
Where possible, store joinery in an upright position and avoid leaning it at excessive angles or placing heavy objects against it.
New construction sites often contain significant moisture from concrete slabs, plastering and masonry work. Keeping timber joinery away from these damp environments until installation will help protect its stability and finish.
Priming and Finishing
Timber should be protected as soon as practical after delivery.
Applying the specified primer, paint or stain system helps minimise moisture absorption and protects the timber from weathering and UV exposure.
Particular attention should be given to:
End grain.
Top and bottom edges of doors.
Hardware cut-outs.
Any exposed timber created during installation or hardware fitting.
These areas are particularly vulnerable to moisture and should always be sealed promptly.
Always follow the coating manufacturer’s recommendations for preparation, application and maintenance.
Looking After Your Joinery
Timber joinery requires very little day-to-day maintenance.
Regular care includes:
Cleaning painted or stained surfaces with a soft cloth and mild detergent.
Removing dirt, salt deposits and airborne contaminants.
Checking paint or stain finishes for signs of wear.
Inspecting sealants and hardware periodically.
Avoid abrasive cleaners, harsh chemicals or high-pressure washing, as these may damage protective finishes.
Coastal and High-Exposure Environments
Homes located near the coast or in exposed locations are subjected to increased levels of salt, UV radiation and weather.
These conditions can accelerate the natural ageing of surface coatings.
More frequent cleaning and inspections are recommended, along with maintaining protective paint or stain systems in accordance with the coating manufacturer’s recommendations.
Regular maintenance helps preserve both the appearance of the joinery and the timber beneath.
Caring for the Finish
The protective coating is one of the most important parts of the timber system.
Over time, all painted and stained finishes will require maintenance to continue protecting the timber.
Repainting or recoating before the existing finish begins to fail helps prevent moisture entering the timber and reduces the need for more extensive repairs later.
If your joinery becomes scratched, chipped or damaged during normal use, repair the affected area as soon as practical to maintain the integrity of the protective coating.
Choosing Colours
Colour selection can influence how timber performs over time.
Dark colours absorb more heat than lighter colours, causing the timber surface to reach higher temperatures during periods of direct sunlight.
For highly exposed locations, this increased heat can contribute to greater movement within the timber and place additional demands on the coating system.
If you’re considering a very dark exterior finish, it’s worth discussing the most suitable options with your joinery supplier before painting.
Hardware and Moving Parts
To keep windows and doors operating smoothly:
Keep tracks and hardware clean.
Remove dirt and debris as required.
Check moving components periodically.
Follow the hardware manufacturer’s maintenance recommendations where applicable.
Well-maintained hardware contributes to the long-term performance of the entire joinery system.
A Natural Material
Timber is a natural material and will respond to seasonal changes in temperature and moisture.
Small amounts of movement are normal and have been considered in the design and manufacture of quality timber joinery.
Understanding these natural characteristics helps set realistic expectations and contributes to the long-term enjoyment of your investment.
