Sealasash went absolutely above and beyond with the repair of my 1950’s windows. The team who came to my home in Hobart were friendly and professional. My windows withstood their first storm the night they were finished, and it is the first time in 5 years the wind didnt make them rattle. My mum is going to book to have her sash windows repaired now too!

The Sealasash team recently completed the total renovation of the windows in our Victorian terrace home. We are thrilled with the result. The noise reduction is dramatic, as is the climate seal. The team were superb. Always on time, very professional and did a great job cleaning up each evening. Their carpentry skills are to be admired! I have already recommended them to our neighbours.


Toorak, Victoria

The work done, the way it was done and the results are all perfect. The guys doing the work completed everything on the job sheet without any hesitation and they left the site clean and tidy. They were well mannered as a bonus! Totally professional.I couldn’t be happier with their work or the product and have no hesitation recommending your company.

The team at Sealasash provide a highly professional and effective service. They respect your home, are very well prepared and communicate well throughout the process. The decrease in noise and the improvement in temperature control/comfort is significant. I highly recommend the service, it will definitely make a difference. Thanks Sealasash!!

Alister, Edgecliff NSW

The first time we engaged Sealasash was to remove, re-hang and draft seal the sash windows in our heritage listed circa 1850 Georgian cottage in Harrington Street Hobart.
We were so impressed with the professionalism of the workmanship and the finished job surpassed our expectations. The windows now slide up and down perfectly, no more rattles and everything left perfectly clean.
A few years on and we wanted to reduce the noise from the traffic in Harrington Street so a phone call to John and Sealasash provided the solution. All of the front windows were re-glazed with thermal acoustic glass. The resulting noise reduction was amazing, our guests constantly remark about the comfort and lack of street noise.
Thank you John, Colm and the Sealasash Team for another fantastic result.

Paul Wagner, Sanctum Boutique Apartments, Hobart

John and his team were efficient, talented and had the expertise to get the job done right. They well and truly exceeded my expectations. Highly recommended!

Karl, Coogee, NSW

We are very happy with the work done, and also with the chaps who came to do the work – polite, friendly and attentive to detail and to our concerns.

Nathan & Jaslyn, Launceston, Tasmania.

Wow! After 10+ years my double hung windows now open with ease. Sealasash has restored them to their former glory without losing their 100 year old look. No more draughts billowing the curtains, no more gaps & no rattling. Dust on the inside ledges are now non-existant & even the outside noise has been reduced. John & colm did a fantastic job, they were on time & left the house in perfect condition. Very impressed with the product & the service given from start to finish. After years of searching for these windows to be fixed sealasash has provided a great solution.

Leanne, New Town, Tasmania.

We are enjoying the secure, as distinct from previously shaky, windows and have also noticed a decrease in noise from outside.

Steve and Martine, Fitzroy, Victoria.

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, Victoria.

Great job, it’s made a huge difference. The team were excellent.

Andrew, New Town, Tasmania

Our building was constructed in the 1930’s. Nearly 100 wooden windows in total in a beautiful art deco building were in need of repair. We as the owners in the building with strata had been putting it off thinking it was going to be too hard. Then we discovered Sealasash. John and Colm were a pleasure to work with. They were able to restore all the windows to fully functioning windows without the need for expensive scaffolding. The windows look fantastic and work a treat. We highly recommend their services”

Ed and Di Scott,  Mosman, NSW

We had the pleasure of meeting Michael Cann at the Melbourne Home Improvements Show in 2017 and the services ‘Sealasash’ could provide seemed perfect for restoring our 1940s sash windows.

The team of Darren, Steve and Chris worked with precision and pride rendering our windows fully operational after many years of immovable frustration. The three worked liked a well-oiled machine, listening to each other, listening to my concerns and never being anything less than professional, courteous and respectful of me, our property and each other.

My invoice in now paid and I could not let this association conclude without highly commending the team and the company in which they work. I will have no hesitation in recommending ‘Sealasash’ to friends in need of a top class operation to repair their windows.

Robyn and Jane, Brighton, Victoria

Our sincere thanks to you, Colm and the team for the truly excellent work that you did on the windows at our house. They are working superbly and we haven’t had a rattle since they were fixed. Our many thanks to the boys for coming around at extremely short notice and on what would have to have been the worst weather possible for the season so far! We really did appreciate their great work ethic and the passion for which they approach their job.

David & Nicole, South Hobart, Tasmania

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, Victoria

We felt compelled to write to you to express our appreciation for your teams efforts in sound proofing our windows. As you know we get traffic noise from the street which has always been a nuisance to my wife and kids sleeping at night. (I’m pretty deaf, but even I can notice the difference) But now! My wife thinks you are heroes! And my kids are finally getting to sleep in! We can’t thank you enough and will be recommending Sealasash to as many people as possible.

Chris & Lucinda, Double Bay NSW

We are very happy with your work… and very impressed with both the process and the outcome. Thanks again!

Carmen and Russell, Bellerive, Tasmania

We are very happy with the service provided.
The boys on site were very good. They were courteous, worked a long day, cleaned up after themselves and made sure they explained how everything worked and the precautions we should take when painting.
We would happily recommend them to anyone.
We are currently enjoying our lovely new open windows on this beautiful day.

Peter, Bayswater, Western Australia

For five years we’ve put up with rattling windows that only opened halfway in summer and leaked heat in winter. But since the Sealasash gurus worked their magic, the place has been toasty like never before – we can even turn off the heater in the evenings and the rooms stay warm – practically unheard of in a Victorian. Dean and Eli arrived punctually and worked incredibly hard to ensure the job was finished with an absolute minimum of fuss and mess. By knock-off time you wouldn’t have even known we’d had the Sealasash crew in – our beautiful stained glass windows looked exactly the same with no unsightly rubber tubing to be seen. We were left with a tidy, quiet, warm home thanks to Colm and the guys. We’re so pleased with the result and would happily recommend Sealasash to anyone looking for a clever, environmentally friendly way to reduce costs on heating and cooling their home. Now roll on summer – we can hardly wait to open our windows to their full extent!

Sue and Stephen, Kensington, Victoria

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, Tasmania

Your men were absolutely fantastic in every way.

Thank you so much. Really happy to have the windows finally fixed.

Amazing job. Super professional and lovely people.

Emma, Bellerive, Tasmania

The night before last, the wind whined and the windows shook. The wind was loud and it was hard to sleep.Last night, after Sealasash Window Renewal system had done their job, there was absolute silence from the windows, despite the strong winds. No wind, whine, rattling and it felt secure and quiet in the house. An amazing difference and warmer too. Thank you!

Gail & Viki, West Hobart, Tasmania

Sealasash renovated 23 windows in our 1920’s beach cottage in Collaroy. Many had been painted shut and they all glide easy now, with no rattling from the wind even during storms. Their tradesmen (real craftsmen) were courteous and careful about cleaning up and not disrupting our lives, so we were very comfortable having them around. The work has improved insulation both for sound and heat transfer and has breathed life back into our home, allowing us to use the natural airflow it was built to enjoy with the modern comfort of a well-insulated building. Sealasash also provided solutions for window fittings and a tricky sliding window to create ease of use and improve the seals. Exceeded expectations in every way.

Jane and David, Collaroy, New South Wales

The windows are great. It is so good to have sealed and functioning windows! Our thanks for a really good job.

Russell & Jennie, Sandfly, Tasmania

John, Colm and their crew did a fantastic job. They were very accommodating to all our requests for different glass in different sashes and arranged the refurbishment of the stained glass as well. They came on time and carried out the work in the time frame specified, they cleaned up all their mess as well! There has been a reduction in our heating bill during the winter months and a noticeable increase in the sound reduction as well. I would thoroughly recommend them to anyone.

Jeremy, West Hobart, Tasmania

The job looks so neat it’s hard to know you’ve been there. We’re looking forward to some cold, windy weather to see how the seals go keeping the elements at bay.

Vince, Northcote, Victoria

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, Tasmania

We are extremely pleased with the windows, the boys did a wonderful job. It has made an enormous difference to our house. The front of the house used to be extremely cold during the winter (no amount of heating could ever warm it up) and hot in the summer. Immediately after the windows were sealed up, the temperature in the rooms has become a lot more stable. We wish we had done it earlier! We are extremely pleased and would be happy to recommend your company to anyone.

Glen & Kasia, Surrey Hills, Victoria

I am very happy to supply a reference regarding the work of Sealasash. The repairs on my windows were undertaken with obvious expertise and in a very efficient manner by a team expert in what they were doing. The team were also very friendly in their approach and happy to discuss various aspects of the work to be undertaken. I was very happy with the finished product.

Dale, Frankston, Victoria

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, Tasmania

We are very happy with the works you did. The house seems to be warmer with the insulation of the windows and the door.

Shaun and Anne, Sandy Bay, Tasmania

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, Tasmania

Just wanted to pass on my thanks and to tell you how pleased I am with the windows which now open and close with ease, no longer needing to be wedged with paper to stop them rattling or to keep them open. Dean, Eli and Joe did an excellent job, they were friendly, efficient and punctual. The bay windows were an exercise in problem solving as they were so bad but the boys worked through it and they are now working well. They did a fantastic job and worked in really well with the glass craftsman who were repairing the leadlight.

Karen, Northcote, Victoria

Thanks Sealasash team – very professional. My wife was even more impressed that you cleaned up after yourselves!

Sergei, Battery Point, Victoria

Thank you for the work on the windows. The silence, from previously rattly windows, on windy days is wonderful.

Kay, West Hobart, Tasmania

Thank you to you and the team – we are very happy with the windows and appreciate how professional you all were and how sensitively you operated in our home.

Tess, New Town, Tasmania

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, Victoria

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, Victoria

Very careful and tidy work. And the windows work better than new ones!

Neville, Richmond, Tasmania

It works!!! Windows work! Fresh air! Very nice to have working windows and have been able to keep the original windows too! Excellent!

Liz, RMoonah, Tasmania

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, Victoria

The guys from Sealasash do a fabulous job and the product more than lives up to expectations. Friendly, helpful and professional service have been the core of all my dealings with them from the initial visit, timely reply with the quote, installation and completion. On the day of installation I was really impressed with their willingness to stay longer to complete the job, their care to protect surrounding areas and the thorough cleaning and tidying up. This is all in addition to a product that has transformed my living conditions. My home is measurably warmer and it’s still a delight to be in charge of the ventilation.

Adrienne, North Hobart, Tasmania

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, Parkdalet, Victoria

I am very happy with my windows thank you. I would also like to say that I have been very impressed with the standard of customer service across the board from your company and would have no hesitation in recommending your company to friend and colleagues.

As soon as the guys came to start the work I was immediatley at ease. They were friendly, professional and really knew their stuff.

Sarah, Melbourne, Victoria

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, Victoria

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, Tasmania

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, Victoria

The guys were fantastic. All were very pleasant, professional and did a great job. They cleaned up so well, you could not tell that they had been there all day, even though they did 5 windows and two external doors and the associated bits and pieces.

I am looking forward to the next windy day or night, and cold or hot weather, to compare the windows that have been done, and those that have not.

Lorraine Huddle, Architect / Heritage Advisor, Ballarat, Victoria

Thanks to Sealasash from lucy our 5 month old daughter! Her window had the Sealasash restoration and it’s the only one in the house that’s not rattling away in these 40 knot winds! Can’t wait to get the rest done!

Luke & Gill, West Hobart, Tasmania

Thank you very much, it all went very well and we’re certainly happy with the windows. With the unusually warm weather at the moment, we’re already greatly appreciating having the windows working again–and also appreciating the peace of mind knowing that the windows are now ready for another 80 or so years of service! The seals seem to work exceptionally well, no drafts or rattles. Dean did a wonderful job–I was really impressed by what he managed to get done. His work is very thorough and clearly of top quality – right down to his attention to the final details like leaving the work site in excellent condition at the end. It really was a pleasure having him with us for the weekend. An additional benefit of the sealing that only became apparent once we saw the seals installed is that they look like they’ll reduce or prevent water ingress and accumulation under the lower sash, particularly for the windows that get prevailing weather. In terms of extending the life of the existing sashes and window frames, for our situation this could in its own right justify the work, before we even consider any of the other benefits.

Josh, East Brunswick, Victoria

We were so pleased with the professionalism and work ethic of the installers who called the day ahead to confirm arrival time, actually arrived on time, and then worked diligently all day to get through the 4 sash windows. They went above and beyond – cleaning the room to a high standard, stripping, sanding & priming the windows so they are ready for top coat, removing old security screens, and patching up holes etc.

As for the product – well the room now is sealed! Which is no small thing for a house built in 1903. The road noise has been dramatically cut far more than we expected as we hadn’t chosen to upgrade the glass. The wind no longer rattles the windows or seeps into the room – and the quality of the finishing touches (the brass pulley, latches & locks) is both aesthetically pleasing and functional (the self-locking latches are a terrific upgrade).

Having had other windows ‘renewed’ by other providers with less impressive results – you can rest assured that the remaining 8 heritage sash windows will be renewed by your group as we slowly move through restoring our heritage home.

Thank you so very much for the great work – we’ll look forward to using you again in due course.

Fr Conway, Mt Lawley, Western Australia

We are very happy with the work done, and also with the chaps who came to do the work – polite, friendly and attentive to detail and to our concerns.

Nathan & Jaslyn, Launceston, Tasmania

Over the winter of 2016, Sealasash worked on our block of 8 apartments to renovate and paint our external windows. They did a tremendous job and the end product has transformed the building. They were in constant touch with us as the Executive Committee, they dealt professionally and courteously directly with tenants / unitholders to alert them to progress. They then performed a thorough clean up of each unit after completion. Overall we were extremely satisfied with the outcomes, and the process to get there, and would have no hesitation to recommend Colm, John and the Seal a Sash team to others.
