What Happens During a Security Door Installation? A Step-by-Step Walkthrough

If you’ve been thinking about adding a security door or screen to your home, you’ve probably wondered what the whole process actually looks like. Will it take all day? Will workers need to pull apart your door frame? Do you need to be home the entire time?

These are fair questions, and the answers are more straightforward than most people expect. This guide walks you through a typical security door installation from start to finish, so you know exactly what to expect before anyone shows up with a drill.

Why Bother in the First Place?

Before we get into the how, it’s worth understanding the why.

According to the Australian Bureau of Statistics, an estimated 218,000 Australian households experienced a break-in in 2023–24, up from 186,000 the previous year. That’s roughly one in every 50 homes. One in five of those households was broken into more than once.

A quality security door won’t make your home invincible, but it does raise the effort required to get inside, and most opportunistic burglars are looking for the path of least resistance.

Step 1: Measuring Up (The Consultation)

Everything begins with a proper measure. Most reputable installers will visit your home first to assess the doorway before any product is ordered or priced.

During this visit, the installer will:

• Measure the door frame opening (width, height, and depth)
• Check whether the frame is square; older homes, in particular, can have frames that have shifted slightly over the years
• Look at what the door opens onto (Does it swing in or out? Is there a step or uneven floor?)
• Talk through your options in terms of mesh type, frame colour, and locking systems

This step usually takes 20–40 minutes. It’s also your chance to ask questions, so come prepared. Ask about the mesh grade, how the door handles cyclones or strong winds, if that’s relevant in your area, and what warranty applies to both the product and the labour.

Step 2: Choosing Your Door or Screen

Security doors and screens aren’t all built the same. There’s a meaningful difference between a basic insect screen with a bolt and a graded security screen that can resist sustained physical force.

The two most common products you’ll encounter are:

Security screen doors, these feature heavy-duty mesh (commonly stainless steel or aluminium) set into a reinforced frame. The mesh is typically tested to Australian Standard AS 5039, which sets minimum requirements for resistance to impact, jemmy attacks, and knife shear. Always ask whether a product meets this standard.

Security doors (solid panel), these use a solid steel or aluminium panel rather than mesh, often with decorative perforations. They offer excellent strength but less ventilation.

You’ll also choose your locking system at this stage. Most security doors come with a three-point locking mechanism, meaning the door locks at the top, bottom, and centre simultaneously when you turn the key. This dramatically reduces the chance of a door being kicked or levered open at a single point.

Step 3: The Installation Day

Once the door has been manufactured or sourced to your measurements, installation day arrives. For a single security door, most professional installers complete the job in one to three hours.

Here’s what happens:

Removing the Existing Screen (If There Is One)

If you have an old screen door or flyscreen, the installer will remove it first. This is usually quick, a matter of unscrewing hinges and lifting the door off.

Fitting the Frame

The security door frame is fixed directly into your existing door frame or, in some cases, into the brickwork or rendered wall surrounding it. The installer will drill fixing points and use heavy-duty screws or bolts to anchor the frame securely.

If the door frame isn’t perfectly square (common in older homes), the installer will shim and adjust the frame so the door sits level and closes properly. A door that doesn’t sit flush is a door with a weak point.

Hanging the Door

With the frame fixed, the door itself is hung on the hinges. Security door hinges are substantially heavier than standard door hinges, and on many models, they’re continuous hinges (also called piano hinges) that run the full length of the door, removing the possibility of hinge-side forced entry.

Fitting the Lock

The lock is installed and tested. The installer will check that the three-point lock (or whichever system you’ve chosen) engages cleanly, that the key turns without resistance, and that the door sits flush against the frame on all sides when locked.

Final Check and Clean-Up

A good installer will test the door multiple times, opening, closing, locking, and unlocking, before they pack up. They’ll also check that the door doesn’t scrape the floor or the frame, and that weather seals (if included) sit correctly.

Any drilling dust or debris is cleaned up before they leave.

Step 4: Handover

At the end of the installation, the installer should walk you through the locking system, hand over any additional keys, and provide documentation for the product warranty. If the door meets Australian Standard AS 5039, ask for written confirmation of this.

Keep this paperwork. Some home and contents insurers offer a discount for homes with certified security screens and doors; it’s worth checking with your provider.

A Note on DIY vs Professional Installation

Security door kits are available from hardware stores, and some homeowners do install them without professional help. However, the strength of a security door is only as good as how it’s fixed to the frame. An improperly anchored frame or misaligned door can undermine the whole point of the product.

For most homeowners, professional installation is the better choice, particularly if you want confidence that the door meets Australian Standards and is installed in a way that won’t void your warranty.

How Long Does the Whole Process Take?

From your initial measure-up to a finished installation, expect the process to take one to two weeks in most cases, longer if you’re ordering a custom size or colour. The installation itself, as mentioned, typically wraps up in under three hours for a single door.

What Does It Cost?

Prices vary by state, product type, and installer. As a general guide, you can expect to pay anywhere from around $500 to $1,500 or more for a professionally supplied and installed security screen door. Solid steel security doors typically sit at the higher end.

It’s worth getting two or three quotes, not just on price, but on the products being offered and whether they carry AS 5039 certification. The cheapest option isn’t always the best one when security is the point.

The Bottom Line

A security door installation isn’t a disruptive or complicated process. In a few hours, you can meaningfully improve how well your front or back door resists forced entry.

Given that Budget Direct’s 2024 Home Burglary Survey found that 50% of Australians already have security screens installed, it’s clearly a measure a lot of homeowners have decided is worth taking. If you’re yet to join them, the process is simpler than you might think, and knowing what to expect makes the decision that much easier.
