Client Testimonials

Great quality security doors, expertly fitted. We appreciated the attention to detail like temporarily removing an existing door to allow exact measurements, reinforcing an aluminium door frame before fitting their sliding door etc. Their price was slightly higher than an alternative quote and definitely worth it. Great people.

Ken & Robyn (Duncraig)

Fantastic prompt service,both efficient cleaned up their mess,will have them back to do other doors.. great price too 😉

Clare & Martin (Tapping)

Excellent Service, Very happy with the product. Would recommend these guys to anyone looking for security for their home.

Scott (Inglewood)

We called the team after a Break and Enter at our residence and really appreciated their prompt and understanding care. The price was competitive and because we have been so impressed we have asked them to look after another property and recommended them to our neighbours and friends.

I am writing to express my complete satisfaction with the new security door fitted last Wednesday. The door appears to be very well made, quite heavy and strong.
The installer was very polite, friendly, efficient and did a great job.
So my whole experience with your company, from the salesperson to completion has been excellent and I applaud you for that!
Yours sincerely,

★★★★★ “Had my front-double security doors fitted today, and I am VERY happy!
Just would like to say how professional Wayne and the team from KNA are but also to commend them on a superior product. Matt (the fitter) took a great deal of care to fit the door, good to see such a quality tradesman!
I chose KNA because of the Invis-guard security mesh and also because the quality of the frame around the mesh. KNA do something (its a secret) that other companies don’t that makes their doors extra strong! Totally happy and would recommend to anyone who is looking to secure their home. Thanks heaps Wayne!” janined4 via WOMO

We already have & will continue to recommend KNA in the future. Hope you, the team at KNA & your families have a very enjoyable Christmas & New Year – you’ve earned it! ~ via email

Evan (Brabham)

KNA did our doors, shutters and tinting too, great service and a friendly team. Nothing is too much trouble for these guys. We have had them back to do more doors and windows a couple of times. I recommend them to everyone and would not use anyone else. Thanks Wayne, Andy, Tim and Kelly in the office for your care and attention to detail. ~ via Facebook

Andrea (Subiaco)

★★★★★ “A refreshing change. Great communication, friendly and knowledgeable. The 2x Sliding Security doors were installed professionally and we are very happy.
Thanks Wayne ~ via WOMO

Tan (Morley WA)

Please would you convey our thanks to the KNA Security team for our three new screen doors – we really are enjoying them!  We especially like that we can now leave our back doors open on hot summer nights knowing that the locked security screen doors are in place and we also like the simple locking device (one rather than the confusing two nibs that you often find on other screen doors).  The doors also look as though they have always been there, which is a welcome relief.
Thanks too for the excellent after sales service including Andy’s prompt return to adjust the front screen door the day after installation.

We hope that our new doors will be trouble-free for many years.

Jasmine & Rose (Cottesloe)

★★★★★ What an awesome crew!… We have had screen doors fitted which just look amazing! Thanks to Wayne who gave us the quote and Matt who fitted our doors, and I am sure the behind the scenes staff in the office and staff who make the doors are fantastic also. And to Andy who changed our front door lock…. Thanks so much for the great customer services you provide… will be recommending you to friends and family

Denise (Yanchep)

“KNA Security were brilliant and I would definitely recommend them. They did an excellent job they were very professional.” ~via Hi Pages

Henry (Burns Beach)

From the very first communication to completion of the job KNA have been a pleasure to deal with, nothing was ever to much trouble.

In today’s environment it makes a refreshing change to see a company that truly values the customer and endeavours to ensure the job is completed on time, to the highest standard and within budget.

I must pay credit to the admin staff for so promptly reorganising a fitting day at short notice after other work scopes at the house ran over schedule and to the fitter who arrived on time and did a wonderful job, leaving the worksite clean and tidy.

The door itself is a great looking product. Initially my wife and I thought it may detract from what we thought would be a heavy, unattractive look to the front entrance, how wrong we we’re. The door looks fabulous. The chap who measured up took the time to match up the colour of the security door to the existing door and windows, which is an off white colour. The security door looks and feels quality and gives us immense piece of mind that any uninvited person is going to have a tough time gaining access through that door.

Probably the best recommendation you can give anyone centres around one question “would you use them again”? my response would be “absolutely, 100%”

Everyone I dealt with at KNA have been courteous, polite and a pleasure to deal with. They offer a great looking product, at a competitive price and a thoroughly professional service, what more could you ask for?

I would like to thank all at KNA Security for a fantastic and professional job.

Kind regards

Steve. (via email)

Steve (Yanchep)

★★★★★ I decided to go with KNA Security to install two double security doors (aluminium diamond grille) as their prices were very reasonable. The staff (Wayne) was incredibly friendly and helpful and I was impressed to see that he responded to some of my emails after business hours – which was unexpected and appreciated.

The fitter (Trevor) knew exactly what he was doing and installed the doors promptly.

Both Wayne and Trevor were on time (in fact, early both for the measure and quote and installation) and Trevor even vacuumed the wood/aluminium scrapings after he finished the job.

It might not seem like much, but responding to emails after hours and vacuuming after the job was finished shows pride and care in their work which is much more than I can say for some other companies/tradies I’ve dealt with.

The quality of the doors and locks were great too and the advice received by Wayne seemed very authentic and specific to my situation.

I’d highly recommend KNA Security.

Andrew (Bassendean)

The man gave the quote as arranged in fact he was early but rang to check if that was ok .Very helpful and good advise.

Told we would wait two weeks for delivery again they were early only about ten days.Rang prior to organise a convenient time and yet again the man arrived early.

Told it would take approx two hours to get doors fitted and yes again it was done sooner.

Doors fitted and look and work perfectly.They didn’t even mind being kissed by my stupid big dog.

Have spoken to colleagues and the price I paid is extremely good so hopefully some more work will come your way.

Thank you

Ann ~ via email

Ann (Wanneroo)

I am more than happy to provide feedback re the installation of security doors at our premises in Yanchep.


Wayne was very professional and knowledgeable in regards to the product and services provided.

Anne was informative and always kept us up to date  re timelines for the collection and installation of the doors.

Trevor was prompt and on time. He collected the front door the day before to have screen replaced and said he would be back at 8.30am the next day to install doors and he was spot on time. Trevor was also very professional in the services provided even to the point where he vacuumed up the metal filings before he left. ( this was much appreciated )

Three words would describe the contact  we have had with KNA Security:

Professional, Prompt and Pleasant.


Thanks again  guys, job well done.


We love our new doors
