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.

"Thank you so much for your kind assistance with repairing the windows. Your integrity is what makes Sealasash a stand-out business - I will gladly recommend to others.
Neil, Parkdale, VIC

"Very careful and tidy work. And the windows work better than new ones!"
Neville, Richmond, Tas

"I am really wrapped with the work that Phil and his team did on the sash windows at our 1840s property.

The windows all work marvellously well, they go up and down with very little effort, no more rattles and it is amazing in the front office how the traffic noise has been reduced.

The repair job to replace the bottom rail and part of the glazing beads on the rear office window is spot on, I believe Eli did this and I was so impressed with his work.

Great job and I will be singing the praises of Sealasash to anyone I know that has sash windows.
Paul, Hobart

"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

"We just wanted to thank those lovely guys for completing the job and working so diligently. We are very impressed with all our windows now. Thank you so much for coming over and for your prompt follow on. Awesome stuff. Really."
Rachel & Colette, West Hobart

"The windows have come up really well, especially the one in the new bathroom! Most importantly the minister for domestic affairs is happy! Your two young blokes were the best workers we have had here, polite, efficient and put drop sheets out and cleaned up totally after the job was done! No hesitation in recommending your product and service."
Rob, Dynnyrne

"The windows are great. It is so good to have sealed and functioning windows! Our thanks for a really good job"
Russell & Jennie, Sandfly, Tas

"When i saw the demo window at the sustainable living festival last year i knew i had to have Sealasash round To fix up my rattling and non-opening windows. My little cottage kitchen is now transformed with a sash window that smoothly opens to the lenah valley hills and which keeps out the drafts when winds blow in!"
Sam, Lenah Valley, Tas
