Diamond Window Cleaning
Excellent service from Matt, who cleaned our solar panels at Belmont North. On time, pleasant, competitive pricing and a great job. Thanks Matt
Matt did a great job cleaning my internal/external windows tracks and screens on my 2 storey house in warners bay. The windows were covered in dirt and mould (due to building sites near by) and were a unique challenge. Matt was efficient, curtious but above all very good value for money. I would recommend him without a doubt.
Recently had a full clean inside and our of glass, screens and doors. Matt was detail oriented, diligent and thorough. Very professional.
Matt did a phenomenal job at cleaning the inside and outside of our windows in our house at Adamstown Heights. He did not miss a single detail including window sills, tracks, fly screens. We are extremely pleased with the work and will definitely be having him back when it’s time again. Affordable price too!
Scott did a wonderful job cleaning out windows inside and out, including all tracks and screens in Hillsborough. Will defiantly be booking in again.
Excellemt Service ! A very hardworker ! Very happy to have clear windows and glass doors etc again. Happy to recommend Diamond Window Cleaning, and Matthew !
Excellent service, prompt response and very accommodating. Used Matt’s solar panel cleaning service and we are very pleased with his professionalism
Professional, friendly, reliable. Matt responded to my SOS to get windows cleaned and stickers taken off as I was leaving my workplace in Bull Street Cooks Hill. He was understanding and accommodating about my time frame. Matt did a great job, clean beautiful windows and lots of light flowing in. Clear about pricing, on time, good with communication and very polite A pleasure to deal with and the job was done well and efficiently. I would highly recommend Matt's services..
Mat did a fantastic job on our large floor to ceiling office windows. They were very dirty and they now look sparkling clean. I was also impressed with the speed of getting the quote done and then the job itself was completed a day early. Excellent communication and excellent results. Highly recommended.
Matt from diamond window cleaning was great to deal with and did an amazing job. We have a large house with lots of glass and the windows came up great.
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 .
Walking into my cafe after Matt has cleaned our windows & mirror.... amazing, Spotless, perfection ⭐️✨️⭐️
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.
Great experience. Same day service and very thorough clean of all outdoor windows for a reasonable price. Would highly recommend
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!
Mat did a wonderful job on our windows. He had lots of fancy equiment and finished the work quickly. We will definetly use him again.
Matt did a fantastic job on multiple large sliding doors and the glass balustrade around our outdoor deck. The balustrade was quite dirty and his attention to detail was excellent! Matt was friendly, very quick with a quote and completed the job efficiently. We will definitely call Diamond Window Cleaning next time we need windows done. Thanks!
Matt was a pleasure to have at our home, polite, friendly and most of all did an amazing job! Matt did a fantastic job of cleaning inside and outside and tracks of all our windows. Would definitely recommend
Matt did a great job cleaning all the windows and screens in my two-storey Charlestown home.
Brilliant results remarked on by other cleaners, prospective tenants and real estate agent. Asked for a quote on an older 4+ bedroom rental with wind out windows, 3 with tracks and a massive sliding door, all with aluminium frames, wooden sills and too many screens to count. I was a professional cleaner and overly daunted at the mountain of a job, especially considering the 4yr battle with excess moisture. It didn't help that the property was constantly exposed to sea storms and runoff from uphill homes. Mathew's quote made me weep with gratitude. He arrived on time and worked around removalists. He brought his own equipment and stolidly ploughed away with a thoroughly professional demeanor while the moving-out-world went to hell around him. He even took care of dicky screen doors. And, on top of all of this, Mathew remained a Nice Bloke. Absolutely happy to give a 7 star endorsement.
I had my solar panels cleaned & I highly recommend Matt. He responded to my email the same day & organised a time kept me in the loop when running late. Firmly in my address book Thanks Matt
Matt was friendly and on time and did a terrific and efficient job, will definitely be asking Matt back
Had our windows cleaned inside and out, including the rails, and Mathew did an excellent job. Everything looks spotless, and the attention to detail really shows. Friendly, professional service – highly recommend
Well done Matt. Solar panels are looking like new. Prompt service reasonable price.
Matt really went the extra mile to make it all look even better.. Great work ethic, shiny clean windows!
Mat recently cleaned our office windows, the service was highly professional. Out of all the companies I contacted for quotes, Mat was the only one who attended our office in person to quote the job. His availability, affordability and attention to detail was excellent. I would highly recommend Mat!

Matt did a wonderful job cleaning up our house including windows, balustrade glass, tiled deck areas and some very mouldy external gutters and fascia’s. He even cleaned the mucky window sills! Our place looks so nice you can actually see the view of our jungle backyard and makes it feel new again!
Number 1 in Newcastle- Fantastic service! Fantastic job! Fantastic staff! Matt was outstanding. He booked us in within the week. He was friendly, polite and professional. Prices are very reasonable. Communication was excellent, as I was organising on behalf of my mum, of which he was very understanding and accommodating. And most importantly the panels are sparkling!

Matt did an amazing job at our house. The house windows, outdoor area and pool fencing had not been cleaned for many years. It’s all looking like new now. We couldn’t be happier with his work, effort and attention to detail
Matt did a great job doing the windows of our 2 storey house. He gave a realistic quote, arrived on time and left everything looking great for Christmas.
Excellent work on our two-storey house which also has heaps of louvre windows! Not the easiest. Plus Matt cleaned the solar panels and skylights which was a huge additional benefit.
Absolutely fabulous job. My windows look cleaner than when I moved in! Great customer service, quick turnaround for job to be done and more reliable than other companies offering the same service. Thanks again for a great job!
Can honestly say my windows have never been so clean - they are absolutely sparkling. Very impressed. Matt did a wonderful job - he was very prompt when supplying me with the initial quote and showed up on time, good prompt messaging to set a date and time and was exactly on time on the designated day. Extremely pleasant guy. Can highly recommend him and will definitely be using Diamond Window Cleaning in the future. Best window cleaner I have ever had. Thank you Matt for a job well done.
Just installed new windows and doors to entire house and fully renovated our yard so as you can imagine our windows and doors were filthy. 2 storey windows, no problem. Everything came out perfect and my wife and I are going to contact them for a regular weekly clean of our pool fence and windows/doors outside that our 5 dogs like to jump all over. Excellent job and would fully recommend.
We had our solar panels cleaned, result was excellent. He was on time, and confirmed his arrival time beforehand. Highly recommended!
Wow!! What a job!! So very VERY happy!! Our new build with beautiful lake views was in desperate need of care and that is exactly what I got!! I requested quote late yesterday afternoon, price was AMAZING for such extensive work, now job is already finished!! We couldn’t be happier!! Thanx so much!!
I contacted Diamond window cleaning to clean my guttering, fascia, eaves and the underside of my carport roof ready for painting. Very reasonable price and the results are fantastic so much so I could probably get away with not having to paint. Thanks Matt. Since posting the above I’ve had Matt clean my solar panels after finding lichen. Another great job and glad to have it removed before the panel degraded. Thanks again Matt.
Matt was prompt with the quote then right on time to do the pressure cleaning job at my in-laws home. So very very thorough and did a fantastic job. We would recommend him to anyone. Did a better job than we thought possible.
Very Highly recommended. Windows, tracks and screens throughout the house cleaned perfectly. On time, easy to get along with and reasonably priced. thanks Mat.

Diamond Window Cleaning did an amazing job on our windows. Our home has some large very high windows which are difficult to access. Matt had them sparkling and streak free. He also did the rest of our windows inside and out including fly screens and tracks. Matt was very professional and hard working. We will definitely get Diamond back regularly to keep our windows looking great.
Want to be amazed at how life changing clean windows can be? I put it out to the universe, like something from The Wizard of Oz. If I could just close my eyes and magically all the windows would be cleaned ✨✨✨ Well we just can't believe that not only does it "look" amazing ... it "feels" so much more amazing than we could have imagined 🩵 So much more open and light ... and the colours of the greenery outside just so much more vivid. Give Matt at Diamond Window Cleaning a call ... you won't be disappointed with the quote, and the job will amaze you. Really priced on point for this not to be a luxury but an affordable treat. Thank you, thank you, thank you Matt .... you're an absolute gem 💎
Awesome job. My windows and doors have never looked so good. Such attention to detail. Friendly service. Support our local businesses everyone. Already booked our next one.
Got Matt's details from a flyer he had dropped in my letterbox and we couldn't be happier with his service. He was prompt to quote and fitted us in to suit our busy schedule. Our windows and screens are so clean that it doesn't look like we have any glass in the windows.
He shined my glass and cleaned my Solar panels 3months later I’m getting double the energy I normally get thanks.
