Windows Maintenance

While timber windows offer terrific durability and trouble-free operation, homeowners need to remember that periodic inspection and simple maintenance will help to keep windows in excellent condition for years.


Follow the simple tips listed here and your timber windows will deliver years of reliable service.

To keep timber window products attractive and functioning efficiently, they should be cleaned occasionally. In most geographical areas, timber windows may require cleaning only a few times per year. However, some coastal, industrial or agricultural areas contain high concentrations of air-borne particles and may demand more frequent washing of your windows.

Most timber windows (casement and awning) can be washed from the inside.

Simply open the window fully and reach between the frame and sash. Wash the sash from the inside, using caution to avoid accidental falls. It is not recommended that you clean glass in direct sunlight and in order to avoid damage to glass, never use razor blades on any glass surface.

Casement and awning hinges need to be cleaned and lubricated occasionally to eliminate squeaking and binding.

To do this, remove grease or debris with a soft, dry cloth, then lubricate hinges and all other moving parts with a dry silicone spray.

Do not use lubricants or harsh abrasive cleaners, as they will break down or collect corrosive particles. Dry silicone spray can be purchased from your local hardware store.

Cleaning grilles, insect screen and hardware
You can usually remove dust, smoke, film, soot and salt spray from grilles using a mild detergent and water solution and a soft rag or brush.

To remove grease, oil or industrial solids, you may need to use stronger cleaning solutions. Insect screens are best cleaned with a garden hose and soapy water. If they have been neglected, wash them with a detergent and water using a soft-fiber brush.

Adjusting hardware

If the operator handle should slip off or loosen, tighten the handle locking (set) screw, making sure the handle is flush with the cover. Leaving handles and locking screws loose may cause stripping. On casement windows with two locks, always engage the bottom lock first.

Preventing condensation
Most interior condensation problems are the result of low household ventilation. By controlling your home’s humidity, you can usually limit interior window condensation. If you are experiencing condensation problems, speak to your WADIC manufacturer or a building professional.

Maintaining door and window hardware
Window hardware (handles, locks, winding mechanisms, hinges, etc) is generally manufactured using high quality, fine metal.

Fine metal requires periodic attention to maintain its beauty and characteristics.

For more information on how to maintain the hardware’s beauty and characteristics, speak to your WADIC manufacturer, building professional or the WADIC Timber Manual.
