Just some comments from clients…

★★★★★ Second time I have used KNA to carry out security door installations at my properties. Highly recommend. They are always happy to come out and quote first, they provide quality service, use quality materials and both occasions I have been happy with the end result. Happy to support this small business. ~ via Facebook

★★★★★ Top service from the moment I booked in! Including the lady on the phone, to the man who gave me the quote, the installer and the man who returned to do a minor adjustment to our door last month. All friendly, helpful and knowledgeable. Highly recommend to everyone and so glad I chose to go with KNA.
Thanks guys. ~ via Facebook

Krystal (Tapping)

★★★★★ Very impressed with our invisiguard security screens on Windows and screen doors. Love the custom size dog door installed into the sliding screen door. Also got tinting done on Windows and love it. Wayne came out to measure & quote, he was extremely informative and covered all questions. Definately recommend. 5 stars. ~ via Facebook

Phillippa (Banksia Grove)

★★★★★ I was extremely satisfied with KNA security from the product to the service. They were really helpful in helping us find the right product and at no time made us feel obligated to buy the doors like some companies do when offering free measure and quotes. The security doors we purchased are top quality and very sturdy as we found out first hand when out 35+ kg dog ran straight into one . I highly recommend them. ~ via Facebook
