“Scott and the team at Downseal have been working with us at Essa Constructions for a number of years, exclusively providing all silicone and sealing on our custom luxury home builds. Always reliable and easily to deal with and consistently delivering a quality finish!”
Ali - Essa Constuctions
“I started using Scott from Downseal last year after spending previous years doing all of my own silicone work, and haven’t looked back since. Scott and his team are reliable, professional, and exceptional at what they do. Nothing is ever a problem for them and they leave every job looking that much more spectacular than when they arrived. I highly recommend Downseal’s services to any builder looking to add that extra level of finish to their projects.“
Keiron - KK License Builder
“We have used Downseal since October 2019 to help with caulking for all our bathroom renovation work, and I have to say they have been a refreshing company to deal with! The guys are committed to both quality and customer service and we're proud to have them as part of the team.”
Steve - Casey Construction
“Had a great experience with Scott and the team, have used on a couple of jobs now and always courteous, polite and great workmanship, rare qualities in todays world, will use again and wouldn’t hesitate recommending”
Lewis - SHAW Property Group
"Scott and his team at Downseal have taken what was a problematic trade for us and completely turned it around. We were getting high rates and terrible services until we gave Scott a shot on one of our custom built homes. Ever since then he has been our only contractor and he will continue to be our only contractor for the foreseeable future. His rates are good and his service is second to none "
Lee - Ambrose Homes
“After a random google when I needed the full house exterior caulked in a hurry, I was lucky enough to get in touch with Downseal Solutions. Scott was a pleasure to deal with and made the whole experience seamless. I approved their quote at 7.30am, and by noon, Max the caulker was onsite getting the job done. Top notch quality, great value, and I’ve never dealt with trades who could match their turnaround time. A very enthusiastic thumbs up!”
