Just some of our many happy clients...

Calk has been providing mastic jointing and sealing services to Resolute Constructions on a number of multi-residential apartment projects.  I would gladly recommend Calk to others based on their high standards of quality and reliability.

Steve Longden Project Manager, Resolute Constructions

We were referred to Calk from one of our existing contractors and our clients couldn’t be happier! After inspecting the finished product, our client was left with a job well done. I would recommend to all and would not hesitate to use Calk for our other clients in the future.

I found Calk prompt, reliable and tidy. Great range of colors and good eye for matching.

I would like to thank you for the impeccable work you carried out on our recent project, I really appreciated all of your advice and assistance. With your help it made the project run a lot smoother, and the long hours you put in enabled us to complete the project on time. I look forward to working with you again in the future. Kind regards,

I've used Calk over the last couple of years and have always found them to be reliable, professional, and always provides us with a competitively priced service.  I have often recommended them to other builders and friends looking for a sealer who knows his trade well.

Whilst working as a building supervisor for one of Perth’s leading home builders I came across Chris and noticed that his work stood out from the pack. Chris carries out the art of waterproofing with pride, he is reliable, honest, punctual and a true professional. Chris’s application of silicone is exceptional, the cleanest and neatest I have seen. I would recommend Chris to work on any category of home.

'We worked with Calk on a major apartment complex in Perth city, they always did whatever it took to stay in front of the schedule when most others couldn't. Throughout the job they maintained a very high standard.'
