Diamond Windows Pty Ltd is a locally owned and operated business in Geelong, Victoria, Australia. Established in 1980 by Laurie Diamond, the company has shown that "expertise, craftsmanship and traditional materials can succeed in this commercial age".

Quality cedar windows and doors are manufactured using Premium Grade, Western Red Cedar, from sustainable plantations. This grade is not always used by some window manufacturers and can affect the lifespan of any window and door. All Diamond Windows, windows and doors are protein treated after manufacture, to prevent moisture uptake. This protects the windows and doors for up to Four months and reduces splitting and cracking while the dwelling is under construction.

Due to the customised service of Diamond Windows, the lead time for delivery is 4 to 5 weeks. Diamond Windows can provide you with doors and windows for a new home, renovation or just a one off replacement. 

Products can be shipped almost anywhere, Queensland, New South Wales, Tasmania and even Korea have been past Diamond Windows delivery points.

All doors and windows manufactured by Diamond Windows are made strictly to Australian Standard Guidelines. This is Diamond Windows commitment to quality, so you can be assured that your order will be structurally sound, windproof, water proof and have an excellent energy efficiency rating.
