Spotted the owners van in my local area whilst walking my dog so I email and hired Diamond.
I had Matt go right around my whole 4 bedroom home in Hillsborough this weekend inside and out as windows were horribly dirty and had mould. Matt cleaned them up amazingly well to a crystal clear finish for a great price. Will definitely use again Thoroughly recommended .

Matt recently cleaned my mother's solar panels which had not been maintained in a very long time. Matt was easy to communicate with, professional and friendly. His services were fairly priced and the quality of his work was second to none. Very happy customers.

Matthew worked wonders with our windows, sills, tracks and screens in our 2 storey home. They had been ignored for ages and he spent a lot of time getting them clean again.
Matthew was very obliging when we had to cancel due to rain and was flexible enough to reschedule.
Extremely pleased with the result. Highly recommended.

My windows, screens and tracks look terrific (and they needed a good wash!) Matthew is genuine and professional. Highly recommend.

Mattew Scott, Diamond Window Cleaning did an excellent job today at my Ridgeway Road, New Lambton Heights house. He used a range of equipment to clean the exterior of a variety of window types on the two storey house. Access to some windows was difficult requiring climbing onto a roof or use of a long extension ladder. He was able to clean some very high windows from ground level using special equipment which enables cleaning with a gentle water lubricated brush. His equipment adds an additive that prevents drying marks. Mattew was very obliging, his price was very reasonable and I thoroughly recommend his services.

We recently had our office windows cleaned by Matt and the results were fantastic! The service was professional, efficient and done with great attention to detail. Our windows are left spotless and we have already booked in our next service! Highly recommend Matt to anyone looking for a reliable, high quality window clean!
