Timber Window Maintenance Guide: Comprehensive Tips for DIY Care

Wood has been a popular material for window joinery for centuries, and its beauty and quality continue to make timber windows a popular choice. These windows not only offer aesthetic appeal but also provide functional benefits for your home. Despite the increasing popularity of PVC and aluminum joinery, timber windows remain a prominent choice in the market.

To ensure the longevity and performance of your wooden windows, proper care and maintenance are essential. In this comprehensive guide, we’ll provide tips on how to maintain your timber windows, divided into four parts: protection, cleaning, repairing, and general maintenance.

Part 1: Protecting Your Timber Windows

Protect against weather and moisture

Wooden surfaces require protective coatings to combat damage from sunlight, moisture, and temperature fluctuations. Regularly check and repair any damaged or peeling coatings to maintain long-term protection.

Guard against harmful UV rays

UV rays can degrade timber windows, causing film depolymerization and deterioration. Inspect wooden surfaces at least once a year, paying close attention to horizontal windows and surfaces exposed to atmospheric influences.

Prevent mold and rot

High humidity can lead to mold, greyish spots, and rotting fungi. Preserve the appearance and structure of your timber windows by maintaining them with suitable protective coatings.

Part 2: Cleaning Your Timber Windows

Clean wooden windows regularly

Clean both the outer and inner surfaces of the windows with water and a mild detergent. Avoid using harsh chemicals, abrasive materials, or strong detergents that can damage the wood.

Remove dust and dirt with a brush

Use a dry brush to clean dust from the surface and renew the outer coating when necessary. Regularly wash the sash and frame with a mild detergent.

Part 3: Repairing Your Timber Windows

Repair damage promptly

Major damage should be repaired by a specialist. For minor damages like scratches and small cracks, use fine sandpaper, wax, and coatings to repair the affected area.

Address visible damage to the frame

If you notice physical damage to the frame, remove minor scratches by polishing. For deeper scratches, raw aluminum is exposed, oxidation occurs automatically – which closes the “wounded” area and prevents corrosion. This type of damage is difficult to repair so that the frame has no visible marks. Our advice is: Leave scratched. This does not affect the long life of the window.

Part 4: General Maintenance of Your Timber Windows

Consult sellers when selecting coatings

Choose a suitable coating for your timber windows by consulting with specialist dealers. Consider environmentally friendly options made with natural waxes and oils.

Care for the window’s moving parts

Lubricate the moving parts of the window several times a year with a few drops of oil. Replace exposed shackles and protect sliding door and window rails from dust as needed.

Clean interior wood parts

Clean the interior of the window with a cloth and mild detergent as needed, depending on the room’s usage and exposure to external factors.
