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

"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

"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

"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

"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

"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

"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

"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 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

"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

"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

"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, VIC

"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

"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

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

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

"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

"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

"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

"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 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
