Full Sash Window Renewal Service

We have found that we need to work on 4 sash windows for our service to be cost effective. For work on fewer windows we need to quote accordingly.

Our set up costs mean it is not possible to visit homes to conduct small repairs on individual windows, but we suggest you consider giving your windows a new lease of life with our complete Sash Window Renewal System.

You’ll be amazed at the difference.

Now operating in and around Hobart, Melbourne, Sydney and Perth.

"Superb draft proofing on both our sash windows and front door that has withstood the gales of winter and contributed to a reduced power consumption. Professional installation done in a friendly manner. Highly recommended"
Cameron, West Hobart

"Thanks to you and the boys for the excellent job with the doors and bay window at Molle st. It has really reduced the cold and the traffic noise.
Cathy, West Hobart, Tas

"We were very happy with the service that both Dean and Paul provided. They were efficient, hard working and very clean. We have also noticed a significant difference in the warmth of the rooms upstairs particularly.
John & Sarah, Berwick, VIC

"The Guys were great!!! So polite & friendly and cleaned up every night. Brilliant!!
They even made sure my new puppy was safe inside by closing the doors each time.
The job has been a great success, has made a big difference to the temperature of the living area. I will refer your company whenever I can."
Kate, Mornington, VIC

"Sealasash repaired four of my windows in my beautiful 1950s home. One of the windows had a gap of over 10mm. The windows are now all working from the top and the bottom and seal without any draughts at all. The fellows from Sealasash were professional, kept within the price of the quote, a delight to watch work and left the place as clean as they found it. I would recommend Sealasash to anyone looking to modernise their windows, even if you have long given up on them. I'm not sure which is better - the free flow of air through windows painted shut for decades or the sealed warmth on icy cold days. Thank you Sealasash."
Kobi, Heidelberg, Vic

"We were immediately impressed with the noise reduction… and we can now verify that for the first time in 20 years we have no more draughts through loose sashes and are yet to switch on the upstairs heating. This is certainly the cost-effective, discreet solution for draughty sash windows that we have been looking for."
Peter and Katie, West Hobart

"I can now highly recommend the Sealasash company, very Professional and amazing Tradesmen. I noticed the difference immediately. NO MORE draughts!!!! The comfort level has improved enormously.
A huge thank you to Colm, John and Phil."
Veronica, West Hobart

"I just had work completed on my house in Victoria.

I am sending this email to commend your company, and more so your staff, on the job they delivered.

Due to many unpleasant experiences, i am extremely critical of any contractors or trades that i have completing work at my house, and i have had a few over the past years. The three gents that i had come to my house to complete these works were the best trades that i have ever experienced. Not only were they punctual every morning, but they were polite and extremely respectful of my household. The were considerate of the mess that the works created, and helped minimise this by covering every services and cleaning up their workspace at the end of each day.

I was very impressed by the way they presented themselves, and you should be very proud to have them representing your company. Whilst the work they completed was great (I have already noticed a difference the draught seals has made), I would be more so likely to recommend your company purely because of your staff.

Thank you for the experience and the works completed.
Nik, Port Melbourne
