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

"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

"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

Rachel & Colette, West Hobart

"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

"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

Marc & Catherine, Lenah Valley, Tas

"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

"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 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 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

"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

"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, TAS

"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

"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

"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

"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

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

"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

"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

"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

"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

"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

"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, TAS

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

"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

"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

"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

"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

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

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

"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

"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. "
Sandra, Toorak, VIC

"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

"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

"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

"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

"From the first point of contacting Colm at Sealasash we received the utmost courtesy and assistance, followed by outstanding workmanship in restoring, at this point, the main bedroom windows in our 1928 Californian Bungalow home to as good as original, particularly with regard to their functionality.
Both David and Eli were prompt, knowledgeable, thorough and efficient, not only with the standard of their work and checking the overall condition of the windows and making an assessment and letting us know of all that needed to be done prior to installing the Sealasash system. Once the work had been completed they also cleaned up everything afterward, that even included the remaking of the bed! “No stone was left unturned” as can be said.
We will be having the remainder of our windows ‘Sealasashed’, as well as our front door sealed, in the near future and look forward to the same professional, caring attention to detail as we’ve received this time.
Miriam and Bert, Ballarat, 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

"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

"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

"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

"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

"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, Melbourne
