It’s a hot and sunny Perth day and the beach is too tempting to resist. But when you leave home, what’s stopping an intruder breaking in?

This may seem like a vague hypothetical, but with 1 out of every 5 Aussie households broken into, the only thing stopping you from becoming a statistic is the security system you install in your home.

For most Perth residents a full CCTV system or motion sensor alarm is overkill. Outside of being expensive, video footage and loud noises don’t stop someone from entering your home and making off with your electronics, cash and valuables.

Instead, Perth homeowners and business owners are turning to the most affordable, and extremely efficient solution – security doors.

Like all home improvement projects though, you’re spoiled for choice, and deciding on the right door is harder than it looks.

In this guide we’ll walk you through each step of your journey, from choosing the right screen door, to weighing up costs, spotting a premium security door from a cheap knock-off, and offering simple tips to protect your home in 2021.

What type of security doors are available?

We know that keeping your family and home safe is the #1 priority, but there are plenty of security door types available to protect your property.

You can choose the materials, colours, styles and designs of your new door, which gives you unlimited flexibility to match your new security doors to your Perth home or business.

Common security doors available in Perth include:

How do I choose the right type of security door?

With so many styles and designs to choose from, it’s easy to feel overwhelmed.

To make your decision easy you only need to answer 3 questions:

  • How much security do you need? A restaurant or shop front in a busy area may need more protection than a house in a leafy suburb of Perth
  • What look are you going for? Stainless steel mesh offers security with no frills, while colonial barrier doors offer more aesthetically pleasing designs.
  • What is your budget? A custom-made security door may cost more than a traditional aluminium diamond grille screen will typically cost less.

When it comes to your choice of security screen, it’s about balancing your wants and your needs. If you live in an area with statistically high break-ins, you may want to opt for a high-end security door with a 3-point locking system.

But if break-ins aren’t common in your Perth suburb, for example you live in the South-West, and you’re looking for peace of mind, you may feel more comfortable with a simple sliding security door with woven 316 stainless steel mesh to keep bugs out while you enjoy the evening breeze.

What do you want your security door to look like?

The material of your door – known as the infill – can be made of steel bars (or decorated steel motif), aluminium grilles, stainless steel mesh, or structural grade perforated aluminium sheets.

Stainless steel mesh is the most popular option on the Perth market, offering a simple and contemporary design that goes with all house types and styles. Aluminium perforated sheets offer the same protection as stainless steel mesh, but offer a visually different experience; while aluminium grilles (typically seen in the form of diamonds) aren’t as strong as the other materials we mentioned, but come in a little cheaper as a result.

What are the benefits of a security door?

Think about the last time you left home for a long weekend. How often did you worry that something might go wrong while you’re away?

It’s natural to want to protect your home and belongings, and with security doors you can. While no measure of protection is 100% foolproof, security doors add an extreme deterrent to would-be intruders who typically target homes without security measures.

When a burglar sees a security door on your property it’s a sign that you take your protection seriously, and that can be enough to scare intruders off.

Security doors also offer light, fresh air and bug-free nights

We don’t need to tell you how hot and stuffy Perth nights can be.

With the average temperature in summer breaking 30°C, keeping the doors open and inviting a cool cross-breeze can make a world of difference. But an open door provides a welcome mat for bugs and pests to enter your home – not to mention the risk of kids or pets wandering off.

While it’s easy to see security doors as being good for one thing (security), they also provide a barrier that lets light and air in, but keeps your family and pets from running into trouble unsupervised.

What to look for in a quality security door

With so many screen door installers and products available at your local Bunnings or hardware store, it’s tempting to pick up a dirt-cheap door and chase savings – but cutting costs upfront can put your home or business at serious risk.

When comparing security doors, keep an eye out for the following crucial features:

✅ Australian Standards

‘Security door’ is a product, not a measurable level of protection. Any Tom, Dick or Harry can sell a door and call it a ‘security door’.

To ensure your doors are up to the task of keeping you safe, look out for products manufactured to Australian Standards – such as AS5041-2003 or above. A security door made to meet this criteria will have been:

  • Pull tested
  • Probe tested
  • Knife shear tested
  • Anti-jemmy tested
  • Dynamic impact tested

✅ Corrosion Resistant 

All security doors are at risk of corrosion, especially if you live near one of Perth’s many beaches, with humid ocean air causing metal to corrode 10x faster than normal air.

To protect against this damage, look for security doors made of corrosive resistant aluminium or stainless steel. A security door that looks stunning but is made from cheap materials will fall to bits while a quality door can stand up to the harsh Perth elements year after year.

✅ Strength of frame

According to data collected through 2020, 47% of Australian households that experienced an attempted break-in suffered tampering or damage to their doors.

When intruders try to gain access, they’ll shake, pull and smash at your security door to try and pull it off, and their success (or failure) comes down to the strength of the frame you’ve got.

A strong frame should have a deep receiver channel for the grille so the edge can’t be pushed out of the frame easily. Reinforced corners can make it even harder for criminals to remove your security door, so always ask about the design and construction of your door’s frames before you spend a cent.

✅ Strength of hinges

The strongest security door in the world is useless if it isn’t fixed to your door frame with equally durable hinges.

For the best protection, your security door should be fixed with 3 hinges that can’t be removed. Installing these at the top, middle and bottom of the door frame provides extra protection and spreads the shock of a blow across the surface area of the door, making it less likely to break if struck by a hammer or other blunt object.

PRO TIP: Keep an eye out for security door installers in Perth who use 2 hinges. Hinge numbers should never be less than 3, so anything less is a major red flag.


Locking systems have been improving year after year, making 2021 security doors a seriously tough obstacle to breach.

All security door key locks should be installed with a five-pin cylinder. Of course, intruders don’t plan on using the locks, but opting for a 3-point lock – instead of a single latching bolt in the middle of the door, there are three spread across the door frame – makes it much harder to pry the door off at the top or the base.

Custom Fit

Perth may be Australia’s most beautiful city (call us biased) but that doesn’t mean it isn’t home to its fair share of creepy crawlies.

Custom security doors will be fitted to your door frame to the exact millimetre. This is crucial for a snug fit that keeps small insects and pests out, and stops any potential burglars from using a tool to jimmy your door open.

Your choice of screen and infill should be snugly fit to your choice of frame with a tight seal.

PRO TIP: As tempting as a discount door from Bunnings can seem, the lack of custom fit is always going to put you at a disadvantage. Your security doors should be installed by an expert to ensure a perfect fit, and to protect you with manufacturer’s warranties.

“I just want stainless steel, will that leave holes in my home’s security?”

Not at all.

It’s common for Perth residents, whether they’re living in Armadale, Freemantle, Mandurah or Northbridge, to lean towards a stainless steel security door – which makes sense as this style is a classic for a reason.

Stainless steel security doors are considered a premium security door based on their level of protection. Looking like a traditional flyscreen (and keeping bugs out in the same way) it’s close to impossible to cut through stainless steel woven mesh without serious power tools (which the average intruder won’t have).

And with the aluminium frame of stainless steel doors able to be customised to suit the colour of your home, you end up with a sleek and stylish door that looks great – but stands up to the worst the outside world can throw at it too.

How much do security screens cost in Perth?

That’s the million-dollar question – thankfully, security screens cost much less than that.

The cost of security doors can be confusing, especially when two seemingly identical doors are priced completely differently. This typically occurs as a result of the frame type, not the infill. So while you might see two doors with stainless steel woven mesh, the frame may be different. One frame may be standard while another is a heavy-duty door using a pressure-retention system instead of rivets.

It’s also important to remember that size will influence your quote. ‘One size fits all’ is a terrible mantra for security doors. Even a few millimetres of the gap can give an intruder enough space to jimmy a door off its hinges or frame.

The following table shows the average costs for each main security door type.

Let’s break down the cost of Perth security doors and give you a better idea of what you’ll need to budget…

Security doors aren’t dirt cheap because they’ve got a crucial function – to keep you and your belongings safe.

You wouldn’t want to spend $20 on a security door if it meant a burglar could put their fist through it and enter your home. At the same time, you don’t want to overpay for home security. To help you budget a realistic spend, here’s a little more info on the cost of Perth security doors.

Custom Perth Security Doors – $800 to $1,200

The cost of your security door will vary according to your needs, but as a rule of thumb you should expect to pay between $800 and $1,200 for a standard-sized door (860mm x 2100mm) with triple locks. This includes aluminium, steel, stainless steel and structural-grade perforated aluminium sheet.

Keep in mind that cost covers the door AND installation, so your money is going towards the product AND the service.

Security Door Variables – $30 and up

Buying generic security doors can lead to trouble down the line if they’re not tailored to your home’s entryways, or matching your home’s decor. Here are a few ballpark estimates for security door customisation. As always, reach out to your security door expert in Perth for detailed pricing and estimates.

  • Non-standard colour: $120 extra
  • Wood-effect aluminium frame: $280 extra
  • Door tracks for a sliding security door: $30 extra
  • New door frame because your existing frame doesn’t meet Australian Standards: $350
  • Extra door installation expert onsite: $85/hour

Are you ready to add the ultimate layer of protection to your Perth home?

Security doors do exactly what they say they will – protect your family and home from the outside world.

Having security doors means going to sleep knowing your property is safe, heading off on holidays without that nagging fear in the back of your mind, and closing up your shop, bar or restaurant for the night confidently.

Choosing between type, style and design can be tough, but keep the needs of your property in mind. Opting for steel or aluminium will provide the greatest protection, while the specific style will come down to your existing decor and your level of required protection.

If you’re ready to let the cool breeze in, not pests or intruders, you’ve got all the info you need to choose the perfect security door.
