How to ensure your products last

Aluminium Products

External aluminium surfaces of windows and doors should be washed with clean water and a mild detergent at least every three months. A soft sponge or similar should be used to avoid scratching the glass or aluminium.

In coastal or industrial areas where the environmental conditions are more demanding, the cleaning program should be carried out on a monthly basis.

Abrasive, chemical cleaners or steel wool should not be used as such methods may result in damage to the glass or aluminium surfaces.

Flyscreens can be cleaned by vacuuming or washing thoroughly using a soft brush. Opening sashes should be operated on a regular basis to ensure the sash hardware continues to move smoothly.

Sliding Windows and Doors

Sill recesses should be regularly cleaned and kept clear of dust and foreign matter. A brush and vacuum within the track area may be used to do this.

Drainage slots should be checked on a regular basis to ensure they have not become blocked with residual dirt or grime, to allow maximum drainage. After cleaning, a light silicon spray may be applied to the track and wool-pile seals to ensure quiet and smooth operation of the sash.

Door locks should be checked from time to time for satisfactory operation and may require adjustment to compensate for building settlement.

Door rollers are factory set and should not require any adjustment. If however, due to building settlement an adjustment needs to be made, the door panel must first be lifted to relieve weight from the roller assembly. Adjustment should be made using a cross recess head screwdriver.

Awning Windows, Casement Windows and Hinged Doors

With sashes open, the sash and opening perimeter should be cleaned regularly and kept clear of dust and foreign matter. Drainage holes should be checked regularly to ensure they have not become blocked.

All door and window operating hardware should be cleaned and operated regularly to ensure smooth operation. Lubricants should not be used on casement stays, as this will affect their operation.

Double Hung Windows

Window jamb tracks should be cleaned regularly and kept clear of dust and foreign matter. Window operating hardware should be cleaned and operated regularly to ensure smooth operation.

Glass

It is recommended that all glass surfaces be kept clean by prompt removal of all dirt or other contaminants. Clean water and in some instances the addition of a small amount of mild detergent should be used.

After washing, any detergent residue must be thoroughly rinsed away with clean water. Under no circumstances is any form of abrasive cleaner to be used. Stubborn dirt or residue should be lightly sponged off to avoid scratching of the glass.

The frequency of cleaning required will depend on environmental conditions such as proximity to the ocean or industrial areas.

As a general guide, glass should be cleaned at least quarterly.

Timber Products

Variations in the colour, texture or grain pattern of the wood should not be considered as defects and are a natural feature of timber.

Timber surfaces exposed to the weather must be sealed using a minimum of two coats of paint, varnish or sealer on both faces and edges top to bottom. Timber finishes should be regularly checked and maintained in order to prevent timber decay.

Frequency of maintenance depends on the environment and finish. Dowell recommend that windows should be re-checked every three months.

Regular maintenance procedures should include:

  • Clean the tracks and sash openings to remove any grit and dirt that has accumulated, this will help to avoid water staining.
  • A silicone spray of the track area and the woolpile seals will ensure a free and quiet operation of the sash. Apply only after cleaning.
  • Door locks should be adjusted properly to suit any settlement that may have occurred in the door after installation. Any loose screws should be tightened.

Maintenance of Glass

It is recommended that all glass surfaces should be kept clean by prompt removal of all dirt. Use clean water and in some instances the addition of a small amount of mild detergent would be of benefit. Thoroughly wash off any detergent residue with clean water. Under no circumstances use any form of abrasive cleaner of any type. Lightly sponge off any stubborn dirt carefully so as not to scratch the glass.

Frequency of cleaning will depend on environmental conditions such as proximity to the ocean and industrial areas. As a general guide, glass should be cleaned at least quarterly stays, as this will affect their operation.
