Maintenance Tips for Aluminium and PVC Windows

27 July 2018

PVC and aluminium have become very popular construction materials recently, being touted as durable, low-maintenance, weather-resistant and affordable alternatives to wood or stainless steel windows. Because of this, a lot of people are switching over to aluminium and PVC windows as their go-to choice whenever they are building or re-designing a home or commercial property.

However, not a lot of people are aware that even these so-called ‘low maintenance’ fittings require some degree of maintenance to last longer and to keep up their best appearance. While not exactly as finicky or delicate as hardwood, iron, steel or brass, aluminium and PVC windows nevertheless do require some maintenance.

Here is how to properly take care of your aluminium and PVC windows:

• Avoid sharp impacts – both PVC and aluminium windows are prone to impact damage, since neither is really designed to resist sharp hard objects. If you want to keep your PVC and aluminium windows looking their best, it is prudent to ensure that they are spared any shock during maintenance by not using any sharp objects while cleaning or scrapping off dirt, grime, or bird droppings.

Using a brush with soft bristles or a non-abrasive cloth and warm water, these are enough to remove anything from the outside of the window frame, and a wet sponge for indoor cleaning. Also, never use alkaline detergent as it can cause corrosion.

• Avoid intense, prolonged, concentrated heat for PVC – PVC is not heat-resistant, and it will warp or melt under extreme heat, especially if it is low-quality PVC. Some PVC mouldings can even soften with nothing more than just the constant direct heat from the sun. To avoid issues, invest in high-quality hardened PVC windows from reputable suppliers.

• Coat or seal your aluminium
– if your aluminium windows are the burnished types that do not have the additional benefit of a chromium coating, it might be prudent to seal it with a specialised sealer or lacquer to ensure that it does not corrode. Aluminium corrodes in a different way than does steel or iron, and will often show signs of corrosion that is typified by the formation of white scaling on its surface.

This can be caused by things like acid rain or a high salt saturation in the atmosphere (especially in coastal areas). Professionally applying a sealant should ensure that this problem is avoided altogether, or, invest in high-quality aluminium windows from a reputable supplier.
