"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

"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

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

"We had trouble finding someone to fix our windows but then saw an add for sealasash. I highly recommend them. No more draughts and rattling windows and great friendly service. We'll be in touch again as we move through the house with our renovations."
Marc & Catherine, Lenah Valley, Tas

"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

"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

"Your work crew were amazing. I was at home because of an eye surgery which meant I actually saw what they did. They arrived on time and worked flat out for over 9 hours both days – the three of them very skilled craftsmen and professional. Nothing was too much trouble and they took great care not to damage anything – no stained glass or other panes broken! So far really pleased that our windows and doors work, there is no cold air seeping – and as a bonus – it’s so much quieter. Living on the street near the city we had got used to a level of back ground noise – the quiet was very noticeable. Thanks also for the invoice being in line with the detailed quote. If I hadn’t been here to see the work in progress I wouldn’t have realised that although it seemed expensive – it was actually really good value. Thank you
Miriam, Glebe, Hobart, TAS

"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

"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, Tas

"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, West Tamar Hwy, Launceston

"We'd both like to thank you and the team for the excellent work involved in installation of the Sealasash recommended draught proofing and glazing to the sash windows in our Perth Federation Terrace house (c. 1902). We were pleased with the earlier work that Sealasash undertook on the timber casement windows in our 1920s weatherboard house in Hobart, in 2014, and the Perth team have exceeded our expectations.

There has been a significant reduction in noise transmission from the road and next door neighbours as well as improved thermal properties - important factors in inner-city living and well worth the initial investment. The sash windows glide smoothly and the seals have worked well in blocking out any draughts. The heavy front door is now straight and opens/ closes with little effort.

The careful preparation work, politeness, and professional carpentry skills were evident throughout the project: we will not hesitate to commission additional work and recommend Sealash and HJW to other prospective clients with our highest endorsement based on extensive experience with renovation of heritage properties in Australia."
Andrew & Annette, Perth, WA

"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."
Trish, Mornington, 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

"Just wanted to give a testimonial. We went through summer without needing the aircon and now in winter it’s very, very obvious how effective the window sealing was. We have not had the heater on more than a low setting at any point. It has made an enormous difference to the comfort of the house and in the electricity bills."
Deborah, Fitzroy North, VIC

"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, Tas

"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

"Thank you very much for the work done so far. It has made such an amazing difference to the house - no more breeze rattling windows or dust! Look forward to booking you in for the remaining windows. Also it was lovely to have such genuine professional & friendly service I know you didn't stop all day to get the job done."
Brooke & Euan, West Hobart

"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

"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, 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

"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

"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

"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

"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

"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 lead light.
Karen, Northcote, VIC

"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

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

"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

"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

"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

"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

"Thanks Sealasash team - very professional. My wife was even more impressed that you cleaned up after yourselves!"
Sergei, Battery Point, Tas

"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

"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, Perth WA

"We are very happy with your work . . . and very impressed with both the process and the outcome. Thanks again!"
Carmen and Russell, Bellerive, Tas

"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, NSW

"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, Tas

"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

"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, VIC

"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, WA

"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

"Great job, it's made a huge difference. The team were excellent"
Andrew, New Town, 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

"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

"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
