Most homeowners should hire a professional security door installer rather than attempt DIY installation. The reason comes down to three things: Australian Standards compliance, warranty protection, and the security risk of a poorly fitted door. DIY can save money upfront, but it often trades that saving for a door that looks secure without actually being one.
TL;DR:
- Professional installation ensures compliance with AS 5039.1:2023, which is essential for warranty validity and insurance claims after a break-in.
- DIY fitting requires precise measurements, structural fixing skills, specialized tools, and can take multiple days, increasing the risk of security weaknesses.
- Cost differences between DIY kits and professional quotes are often minor once tool hire, mistakes, and frame repairs are factored in, with custom, compliant doors costing more upfront.
- Small errors in DIY installation, such as gaps or misalignments, can largely negate the security benefits of a quality door.
- When framing or opening irregularities exist, or warranty and compliance matter, hiring a licensed professional is the safest and most reliable choice.

Security door installer vs DIY: comparing real costs
DIY security door kits and fly screen frames typically run cheaper on paper, but the comparison rarely stays fair once tool hire and mistakes enter the picture. A basic aluminium screen door kit might look like a bargain at the hardware store, yet you still need to hire a drill press or angle grinder, buy hinges and a lock set separately, and budget for a second attempt if the first cut is out of square. Custom, professionally installed security doors cost more from the outset, but that price includes measurement, manufacture to fit, and a finished product that carries a compliance label.
A few factors push professional quotes up or down:
- Door type and material. Stainless steel mesh doors generally cost more than aluminium, reflecting the extra strength and corrosion resistance.
- Frame condition. A rotted or out-of-square frame adds labour before the new door ever goes in.
- Access and opening size. French doors, double doors, and oversized openings all take longer to fit than a standard single door.
When you read a quote, check whether it separates the custom manufacture cost from installation labour and any frame repair. A quote that bundles everything into one number makes it harder to see where your money is actually going.
How much skill and time does a DIY install take?
Fitting a security door well is less about brute strength and more about precision. Get the measurement wrong by even a few millimetres and the door either binds in the frame or leaves a gap wide enough for a lever attack. Hinges need to sit dead level, and the lock must line up with the strike plate on the first attempt, because redrilling a steel frame is not a five-minute fix.
Here’s roughly what a DIY job demands:
- Accurate measurement of the opening, checking it’s square in both directions, not just top to bottom.
- Structural fixing skills to anchor the frame into masonry, brick, or timber studs, not just the plaster or cladding surface.
- Specialised tools, including a hammer drill, masonry bits, a spirit level, and often a hinge jig, most of which need to be hired if you don’t already own them.
- Time on site, generally a full day for a single door and closer to two days for French or double doors once you allow for mistakes and adjustments.
Our measuring guide walks through exactly where these measurements tend to go wrong.
What does AS 5039 actually require?
Australian Standard AS 5039.1:2023 sets performance requirements for security door and window screens, covering hinged, sliding, folding, removable, and fixed screens across residential and commercial buildings. It specifies how much force a compliant door must resist and includes installation instructions, because a door that passes lab testing can still fail in the field if it’s fitted incorrectly.
The National Security Screen Association warns that many buyers confuse a “barrier” door, which offers little real resistance, with a genuine AS-compliant security door. Only the second type carries a physical compliance label.
Before you commit to any door, run through this:
- Ask to see the compliance label attached to the product, not just a claim on the box or invoice.
- Confirm the installer is licensed for building work through your state’s register, such as the QBCC licensee register in Queensland.
- Understand that installation quality itself affects compliance. A compliant door fitted badly is no longer performing to standard, because AS 5039.1 ties performance to correct fixation as well as the product itself.
The warranty and insurance risk nobody mentions
Manufacturer warranties frequently include a clause requiring professional installation for cover to remain valid. Fit the door yourself and you may find the warranty voided the moment something goes wrong, whether that’s a failed hinge or a lock that seizes after twelve months.
The bigger risk shows up after a break-in. Without a compliance label properly fixed and installation records to back it up, insurers can dispute a claim on the basis that the door never met the security standard it was sold under.
Keep a simple file for peace of mind:
- Photos of the compliance label before and after installation.
- The installer’s invoice, showing licence details and scope of work.
- Any warranty documentation confirming professional installation as a condition.
Timeline: what to expect from each route
Professional installation follows a fairly predictable sequence:
- On-site measurement, usually booked within a few days of your enquiry.
- Manufacture, which takes longer for custom sizes or non-standard finishes.
- Installation, typically completed in a single visit, including frame repair and weatherproofing where needed.
A DIY timeline looks messier. You’re shopping for parts, measuring (sometimes twice, after the first attempt goes wrong), prepping the frame yourself, and then spreading the install across a weekend or more. Professionals build in time for frame repair and weatherproofing up front precisely because skipping that step is what generates callbacks and warranty claims later.
Where DIY installs quietly lose their security value
Small errors during a DIY fit can undo most of the protection a security door is meant to provide.
- Loose fits and measurement gaps create room for a lever or pry bar to get purchase on the frame edge.
- Fixing into render or cladding instead of the stud or masonry behind it means the screws hold decoration, not structure.
- Misaligned hinges or locks cause doors to bind, which owners then “fix” by loosening fixings, weakening the whole assembly.
- Mistaking a barrier door for a security door leaves you with a product that was never tested to AS 5039.1 in the first place, no matter how solid it looks.
Pro Tip: If you’re set on DIY, buy a pre-certified door and have a licensed installer check your fixings before you consider the job finished. A ten-minute inspection can catch a fixing error that would otherwise go unnoticed until someone tests it from the outside.
When should you hire a professional installer?
Run through this checklist before you decide:
- Is the opening irregular or out of square? If yes, custom manufacture and professional fitting almost always beat a stock DIY kit.
- Does the frame need repair first? Rotted timber or damaged masonry is a job for someone experienced in structural fixing, not a first attempt.
- Is the property coastal or exposed to salt air? Corrosion resistant materials and correct sealing matter more here, and mistakes are expensive to fix twice.
- Do you need warranty cover? If a lifetime or extended warranty matters to you, professional installation is usually a condition, not an option.
- Do you have the tools and confidence to redo a fixing if it fails? If not, the labour-saving from DIY shrinks fast once you factor in a second attempt.
When you do call installers for quotes, ask directly: Is the door AS 5039.1 labelled? What warranty applies, and does it require professional fitting? Are you licensed for this work, and can I see proof? What exactly does the quote cover, start to finish?
What professional installers actually do on the job
A proper installation starts well before anyone touches a drill. A proper installation starts with an on-site consultation: inspecting the opening, taking precise measurements, and recommending a door type suited to the property and the level of security needed.
From there, installation steps typically include:
- Frame repair or reinforcement where the existing opening isn’t sound.
- Hinge and lock alignment checked and adjusted on site, not assumed from the factory setting.
- Weatherproofing to stop water ingress around the new frame.
- Final testing of the lock and door action before handover.
- Compliance paperwork provided, which activates warranty cover and gives you something to show an insurer if you ever need it.
A homeowner’s bottom line on this decision
If compliance, warranty, and real security performance matter to you, hiring a professional is the sounder call for most homes. DIY can work for confident, well-equipped homeowners tackling a simple, square opening, but the margin for error is thin. If you go professional, get two or three quotes and ask each installer, in writing, what their warranty covers and whether it requires their own installation.

Get a measure and quote from a professional installer
Professional installers handle the part of this decision that DIY can’t: a door that’s measured, manufactured, and fitted to actually meet AS 5039 rather than just resemble it. Unlike a hardware store kit, where you’re guessing at fit and hoping the fixings hold, they start with a free on-site consultation, measure your exact opening, and custom manufacture a door built for it.
That process covers everything discussed above: frame assessment, hinge and lock alignment, weatherproofing, and paperwork that keeps your warranty and insurance cover intact. Whether you’re after aluminium security doors or a stainless steel option, the same measure and quote process applies. If your home needs a door that’s genuinely fit for purpose rather than fitted in a hurry, book a free measure and quote through Easterndoors and get a proper answer on cost before you decide anything.

FAQ
How much should it cost to install a security door?
Costs vary with door type, material, and frame condition, with custom stainless steel or steel doors generally costing more than standard aluminium options. Many professional installers provide a free on-site measure and quote so you get an exact figure rather than a guess.
Are security doors easy to install yourself?
Not really. A DIY install demands accurate measurement, correct structural fixing, and precise hinge and lock alignment, and small errors in any of these can weaken the door’s real security performance.
Does DIY installation void the manufacturer warranty?
Often, yes. Many manufacturer warranties specifically require professional installation to remain valid, and installing a kit yourself can leave you without cover if something fails later.
How do I know if a door is genuinely AS 5039 compliant?
Check for a physical compliance label on the product itself, not just a claim in the listing or on the box, and ask your installer to confirm the door meets AS 5039.1:2023.
Is it worth hiring a professional installer instead of doing it myself?
For most homes, yes, particularly if the opening is irregular, the frame needs repair, or warranty cover matters to you. Professional installation processes include frame checks, alignment, weatherproofing, and compliance documentation that a DIY kit can’t replicate on its own.
