We used Windowline to replace windows in a 1960’s strata block of 15 units - the project completed in September 2024 and we are very happy with the result. I was particularly impressed and grateful for Harley’s great communication in the initial phases (at the time of inspecting for the quote and in the lead up and throughout the course of our EGM). He came along to our EGM and dealt with questions from the owners very clearly and responded quickly to further questions. The installation process was pretty seamless with only a couple of minor hiccups. The workmanship is great with my only complaint being that the outside of the windows could have been left cleaner (some were quite smudged)I would highly recommend Windowline for strata window projects

The installation of new double glazed windows and balcony doors on the entire block of units including our unit 8 was professionally done and the communication throughout the process was very good. This was a pretty complex job and we can’t recommend Windowline highly enough!

The Windowline installers were polite, friendly and hassle free. Left our apartment clean afterwards and the new windows look great 👍. Areas for improvement: A couple of the windows need the springs adjusted, as they fall open if not locked. Windowline advised how to adjust it, but the screws in question are not easily accessible, so we still have this issue. The other thing that could be improved is that, due to government regulations, the bottom window has to be blocked from opening too wide, which means you have to open the top window if you want your windows fully open for ventilation. But the top windows are not designed this way. If you want to open the top window, you have to grab it at the very top, which usually requires a stool or step ladder! Same for closing! This issue is due to government regulations to prevent children falling out the bottom window, so it’s not Windowline’s fault. However, it does affect the practical function of the windows and therefore could benefit from a design rethink. Overall, very happy with the fresh new look of the new windows!— R. Gowland, Unit 13.

David was a great salesman who led our owners through the options available and helped guide owners to a good solution.A couple of early hiccups during installation were resolved and with 1 of 96 windows needing additional attention we are close to a good result.

A company representative contact me to arrange to came and measure for the replacement window. He arrived on time and was thorough in measuring up. Two weeks later they came and installed without fuss or mess I would certainly recommend this Company.

Windowline replaced the windows in my apartment, they were very fast and efficient but more importantly (as someone living alone) they moved furniture away from the windows and then cleaned and returned the furniture to its original position while I was away at work. I was able to come home to my apartment after a long day with very little inconvenience which I greatly appreciated. This made the process easy and they were very friendly and accommodating. Would highly recommend the guys from windowline!

Absolute pleasure to deal with this company. From the service from David and Craig, No problems from start to finish. Special mention to the installers Zac and his team, Lisa and Daniel. After 20 years in the property game and using 100s of contractors. These guys were 100% percent professional, flexible and a joy to work with. The finished product was better than expectations.

Avoid.Came home expecting a complete job. Instead, our bedroom windows had been half installed leaving a gaping floor to ceiling hole in the middle of winter. Tools were left everywhere, including a stanley knife on my bed. Window frames had also been left in our lounge room for several days.Came home a seperate day to find that our front and side doors had both been left open whilst the team had gone off to lunch. So anyone could have accessed our apartment.After weeks, there had been no clean-up to the common areas, with shards of glass and wood splinters being left across all walkways and garden beds.

If you aren’t in a hurry, hire Windowline. I was just a renter when Windowline completed the strata building works, but suffered the consequences of it all. Overnight we were left with gaping, floor to ceiling holes in our walls when they ‘ran out of time’ to finish the window installation. Who doesn’t love an icy cold breeze flowing through their entire apartment in the middle of winter. We also appreciated that on multiple occasions our apartment was left with doors wide open with no tradesmen in it while they went to lunch. Its fun waiting an hour for them to return so you can continue on with your day to day business and avoid leaving the apartment open and unattended again. What an excellent feeling to come home to an unlocked apartment with no one in it and not have to find your keys to open the door. I’m glad no one decided to pop buy and steal our possessions. They made themselves at home and decided to use our apartment to store the window frames in for a fortnight. Great feature of our living and dining area, and was fun to navigate around. The best part was how much time we had to take off work to be there for them as they were always late and seemed to take multiple days to install each window. I take that back, the best part was how they ruined the timber flooring and left dirty hand prints on ever inch of surface.
