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 and Melbourne.

"I am thrilled with my windows. They used to rattle all night and keep me awake. Having them sealed has changed my life!"
Helen, Albert Park, VIC

"Thanks for doing a great job and for the way you went about it. I trusted you right from the start, which is the thing that matters most to me."
Ian, Fitzroy, Melbourne

"We heard about Sealasash from the Sustainable Living Festival. Of all the things my art deco apartment needs work on, the sash windows were at the bottom of the list, as I'd just concluded (incorrectly) that it wouldn't be cheap to fix. Throughout the whole experience, the guys were extremely professional, personable, and their work is brilliant. Not only are draughts a thing of the past, but I am particularly surprised at how much noise is suppressed. They weren't expensive, brought their own equipment (including a vacuum cleaner!). Oh, and the best thing? There were not only on time but cleaned up thoroughly after themselves."
Jason & Robyn, Hawthorn, Melbourne

"John and the Sealasash team did an outstanding job repairing a difficult bay window and 4 sash windows in my 1909 weather board property in North Hobart. The attention to detail in the craftsmanship and the restoration of original features including brass fittings, along with the draught-proofing, has significantly enhanced the look and comfort of my property. John also organised for an excellent painter, Noel, to repaint the frames.

They all worked in extremely challenging weather conditions to exceed my expectations in craftsmanship and professionalism. I would have no hesitation in recommending Sealasash to anyone who wants to restore and enhance period sash windows."
Jo, North Hobart

"Sealasash restored a 100 year old, bay window containing 5 individual sash windows and 3 additional sash picture windows for us at our North Hobart property. Over the years previous owners had attempted to repair the rotting frames but in the process made matters worse, with none of the windows opening but letting in drafts and water.

Keeping the period character of the home was very important to us and finding Sealasash was terrific. Our only alternative to fix the rotted, leaking windows was to have new ones made, which would not have been authentic and not looked in keeping with the age of the property.

From the start of the process of quoting for the work, right through the restoration process, we were kept informed of progress and costs. The restoration team did an outstanding job of workmanship under difficult weather conditions, with minimum disruption.

We have no hesitation in recommending Sealasash to anyone wanting a 100% professional restoration job."
Jo & Chris, North Hobart

"I have had windows repaired by Sealasash in a heritage building in Hobart. I am very happy with the result - the windows now glide up and down. The counterweights are doing their job beautifully. The upper sashes open - having previously been painted shut who knows how long ago. It is a pleasure to open and close and adjust the windows now.!"
Joanna, South Hobart

"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

"Recently had all our windows sealed. The work was completed with maximum efficiency and minimal disturbance and mess. A big storm came in just 24 hours after the work was complete, and we could not believe the difference in the noise level (no banging or rattling). In addition we have really noticed that the house does not get cold like it did last winter."
John & Tonya, Wonthaggi, VIC



Our work on heritage properties reached a pinnacle recently when we carried out work on two large double hung sash windows in the dining room at the World Heritage Listed Woolmers Estate in Northern Tasmania. With such valuable artefacts around – the site is a museum of historical items dating back to mid 1800’s – […]
