Caring for your windows

Follow our useful tips below

  • uPVC and Aluminium

    When exposed to wind, pollution, rain and other elements, windows will become dirty. Dirt shouldn’t damage Everest windows, but you may wish to clean them based on the following guidelines to keep them looking at their best.

    In towns and cities, or near coasts, you should clean them every three months. In rural areas, twice a year should be fine.

    General Cleaning

    • For general cleaning use a soft cloth and water with soap or washing-up liquid
    • To remove grease marks, use washing-up liquid with little or no water, then rinse with clean water
    • Do not use glass cleaner on frames
    • Do not use kitchen / bathroom cleaners

    Tough Stains

    • For long-neglected uPVC use a uPVC cream cleaner
    • For long-neglected aluminium use washing-up liquid with little or no water, scrub with a stiff fibre brush and then rinse with clean water

    Never Use – the following methods and items are likely to cause corrosion or damage to your Everest products

    • Any other cleaning agent
    • Caustic or ammonia-based cleaning agents
    • Scouring powder or other abrasive cleaners
    • Steel wool or scouring pads
  • Timber

    All our timber frames are made from specially selected, seasoned wood. The wood has natural properties that will help it withstand the elements but to make it last even longer we apply a ‘colour harmonising’ finish in the factory, which contains a preservative. We then apply a micro-porous protective stain or paint finish.

    General Cleaning – carry out regularly at least twice a year

    • For general cleaning use a soft cloth and water with soap or washing-up liquid
    • To remove grease marks, use washing-up liquid with little or no water then rinse with clean water
    • Do not use glass cleaner on frames
    • Do not use kitchen / bathroom cleaners

    Wood is not indestructible. Maintenance of the coated finish is important, not only to keep the window or door looking good, but with the correct maintenance your products should last even longer than their guarantees.

    To Recoat

    It is recommended that the surface coating is inspected annually and if required you should re-coat the wood with micro-porous stain or paint.

    Here’s how:

    • Clean the window or door as above and let it dry completely
    • Use a fine grade of wet and dry silicon carbide abrasive paper to lightly rub down the existing paint or stain finish (do not try to rub through the existing coat. This exercise is intended only to remove any grease and dirt and provide a smooth surface)
    • Remove all dust and debris with a wet cloth, taking care to avoid inhalation of the dust
    • Allow to dry thoroughly
    • Apply the micro-porous finish with a brush, taking care not to overload the brush or get the finish on the seals or gaskets
    • Only use micro-porous paint or stain. Avoid non-micro-porous finishes such as yacht varnish as they need stripping and renewing more often. And you should follow the instructions on the container carefully.      

    Scratches and Chips

    • Damaged timber should be re-painted or re-stained immediately
    • First, prepare the damaged area by removing all surface damage with a light abrasive following the line of the grain
    • Remove all dust and debris with a wet cloth, taking care to avoid inhaling the dust
    • Where necessary, a timber filler may be used to repair the damage and provide a smooth surface for reapplying the finish
    • Re-apply the finish to the damaged area as described above

    Failure to treat scratches and chips will invalidate the product guarantee.

    Knots, Grain and Movement

    Wood is a natural product and features such as knots and differences in grain appearance do occur. This is not a fault but part of the natural beauty of our timber product. As a natural product some degree of movement in terms of expansion or contraction can be expected.

  • Standard glass

    General Cleaning

    For general cleaning, use a soft cloth and water with soap or washing-up liquid.

    Tough Stains

    • Use a commercial window cleaning solution or cream
    • Follow cleaning product instructions
    • Keep solution or cream away from the frame
    • Wash away residue with clean water

    Avoid

    • Do not use creams containing abrasive pastes
    • Do not use steel wool or razor blades on stubborn marks

    Leaded Glass

    After a period of time the lead naturally becomes weathered and the oxidisation will be of a uniform colour. The time will vary from installation to installation and even from window to window, depending on the degree of exposure to the elements and whether the installation is in a rural or urban environment. We do recommend that you be patient and allow the natural process to take its course

  • Self-cleaning glass

    The internal panes of glass can be cleaned following the guidelines above for cleaning standard glazing. The external surface of the self-cleaning glass should be cleaned according to the following guidelines:

    Activation

    The properties of Everest self-cleaning glass can take up to one month to activate. Activation depends on the level of sunlight and therefore can take longer in winter months

    General Cleaning

    Normally the sun and rain are enough to clean the external panes of self-cleaning glass. Between rainfalls, you can hose the glass down. In hard-water areas, reduce milky white mineral deposits by adding solvent-free detergent via a suitable applicator

    Tough Stains

    Apply a soft cloth with soapy water, then rinse. If necessary, use a non-abrasive liquid glass cleaner

    • Take care not to trap dirt in the cloth
    • For wet paint or ink, use a soft, clean cloth and methylated spirits right away, then rinse
    • For dry paint or ink, use the same but keep dabbing spirits on with clean areas of cloth
    • Do not rub spirits into the paint or ink as it can remove the coating

    Avoid

    • Do not use rubber squeegees, metal scrapers, razor blades, steel wool or any other hard object – they will damage the self-cleaning surface
    • Do not use cream cleaners, functional products (such as anti-mist) or any other chemical products as they may either damage the self-cleaning coating or leave a film over the top of it and stop it from working
    • Do not let alkali from concrete leach onto glass

    NOTE: After manual cleaning, the self-cleaning coating takes a week to reactivate.

  • Condensation

    There are certain weather conditions throughout the year - usually during autumn and spring - that leads to condensation forming on the outside of certain windows. This can cause people to believe their windows are faulty, but more often than not it’s a transitory effect that clears within a couple of hours.

    Condensation appears on a surface when it’s cold, due to factors such as outdoor weather, and then water is released into the air. Single glazed windows and bathroom mirrors are often exposed to condensation because of the warm, moist air created when running baths and showers, and your kitchen windows may experience temporary condensation when cooking.   

    When a window drops below its “dew point,” condensation will appear on the surface. As a rule, the warmer the window, the less likely it is to attract condensation. This means windows that are made-to-measure, and units that boast double or triple glazing, suffer far less from condensation as they retain more heat.

    However, in the case of Pilkington-K low emissivity glass, which provides particularly great insulation and allows less heat through it, the pane feels cooler from the outside. Therefore, if cold overnight temperatures are followed by a sudden temperature rise or moisture in the air, condensation may appear externally until the window temperature exceeds the dew point, when it will completely disappear.
