Timber windows and doors are designed to provide many years of performance and beauty, but like all natural materials, they benefit from regular care and maintenance.

With a few simple steps, you can help preserve the appearance and lifespan of your timber joinery for years to come.

Factory Applied Paint & Stain Finishes

Your timber windows and doors are factory finished using a high-performance microporous coating system. Each product receives a base coat primer followed by two finishing coats of either paint or stain.

Under normal conditions, this protective system can last:

  • Up to 12 years for painted finishes
  • Up to 6 years for stained finishes
  • Approximately 1 year externally for stained oak products

Information

The lifespan of the coating will vary depending on factors such as exposure to weather, building elevation, coastal environments, and direct sunlight.

Regular cleaning and inspection will significantly extend the life of the decorative finish and reduce the need for major maintenance.

Routine Cleaning
& Maintenance

To maintain the integrity of the paint or stain finish, timber windows and doors should be cleaned at least twice a year. In coastal areas, heavily polluted environments, or north-facing elevations, more frequent cleaning may be required.

Routine cleaning helps remove:

Dirt and Dust

Insects and
airborne contaminants

Algae and
fungal spores

These contaminants can damage the coating over time if left
untreated.

How to Clean Timber Windows & Doors

  1. Wash surfaces using warm soapy water and a mild liquid detergent.
  2. Frequently change the cleaning water to avoid spreading dirt.
  3. Rinse thoroughly with clean water.
  4. Dry surfaces with a soft, clean cloth.

Avoid using:

Pressure washers
Hose pipes
Abrasive cleaners
Harsh chemicals or solvents

These can damage the protective coating and may invalidate your paint or stain warranty.

Areas That Need Extra Attention

The lower sections of windows and external cills are the most exposed to weathering and moisture. Rainwater naturally collects in these areas, making them more vulnerable to coating wear.

During cleaning, inspect for:

Cracking or peeling paint
Exposed timber
Swelling or softening wood
Water retention on cills or lower frame sections

Caring for North-Facing Windows

North-facing elevations tend to remain colder and damper for longer periods, creating ideal conditions for algae and mould growth. If left untreated, fungal growth can affect the coating system and potentially lead to loss of adhesion or coating failure.

Removing Algae & Mould

If any coating damage is discovered during cleaning, repairs or recoating should be carried out as soon as possible.

This process may need to be repeated periodically depending on environmental conditions and the speed of regrowth.

Areas That Need Extra Attention

With regular cleaning, routine inspections, and prompt attention to minor wear, your timber windows and doors will continue to perform beautifully for many years.

A little ongoing care helps protect both the appearance and structural integrity of your timber joinery – ensuring it remains an attractive feature of your home for the long term.
