Yes, Crimsafe can be installed on older homes, heritage-style properties, and unusual window or door openings when the system is properly measured, custom-fitted, and installed by experienced professionals. Ready to stop worrying about home security? Your family’s safety is your top priority, and modern security screens now make it possible to protect older Queensland homes without compromising their character, airflow, or street appeal.
Queensland homes are rarely standard. From classic Queenslanders and post-war homes through to architect-designed properties with arched windows or oversized sliding doors, many homeowners assume security upgrades are difficult or impossible. In reality, modern Crimsafe systems are designed to adapt to a wide range of openings, materials, and layouts. At Securelux, we regularly help homeowners across Brisbane, Ipswich, Moreton Bay, and the Gold Coast secure homes that were built decades before modern security standards existed.

Can Crimsafe Be Installed on Older or Heritage Homes?
Older homes are often the properties that benefit most from upgraded security screens. Many Queensland homes built 30, 40, or even 80 years ago still rely on outdated locks, ageing flyscreens, or thin window frames that provide very little protection against forced entry.
The good news is that Crimsafe products can usually be retrofitted onto existing homes without major structural work. This includes traditional Queenslanders, heritage-listed homes, post-war brick homes, timber cottages, and older aluminium window systems.
One of the biggest misconceptions is that installing security screens will ruin the look of an older house. In practice, a properly designed Crimsafe screen is subtle, clean, and custom-made to suit the existing architecture. At Securelux, our expert team carefully measures every frame to ensure the product integrates with the property rather than standing out awkwardly.
Why Older Homes Often Need Better Security
| Common Issue | Security Risk |
|---|---|
| Ageing timber windows | Easier forced entry |
| Old flyscreens | Minimal protection |
| Worn locks | Reduced safety |
| Uneven openings | Gaps around standard screens |
| Large patio or outdoor access points | Multiple entry opportunities |
Modern Crimsafe technology helps address these vulnerabilities while still allowing ventilation, outdoor views, and natural light. Crimsafe’s stainless steel mesh, screw-clamp fastening system, and Tensile-Tuff technology are designed to exceed Australian Standards for impact and intrusion resistance.
Can Security Screens Be Custom-Fitted to Arched or Unusual Windows?
Yes. Security screens can be custom-made for arched, angled, oversized, narrow, or non-standard windows and doors. This is one area where professional measuring and installation make a major difference.
Many older homes include unique design features that cannot be used with off-the-shelf products. Securelux uses in-home measures and custom fabrication processes to create screens designed specifically for the opening dimensions and operating style of the home.
Common unusual openings we work with include:
A standard flyscreen system usually relies on lightweight aluminium and basic mesh held together with simple corner joins. Security screens are entirely different. Crimsafe screens use high-tensile stainless steel mesh, heavy-duty frames, and strong fastening methods that allow the screen to maintain strength even on unusual openings.
For example, arched windows require curved frame manufacturing and precise fitting to maintain structural integrity. Similarly, older timber windows may need specialty fixing methods to ensure the screen remains secure without damaging the original frame.

How Securelux Preserves the Character of Older Homes
Homeowners often tell us they want better security without making the house feel like a fortress. That concern is completely understandable. The best security solutions should complement your lifestyle, not dominate it.
At Securelux, we focus on preserving the look, comfort, and value of the home while improving protection levels. Our team works with homeowners to find options that suit both modern and traditional Australian homes.
Our Simple 3-Step Process
- 1
In-home consultation to inspect windows, doors, locks, and unusual openings
- 2
Custom measure and product selection based on your home’s design
- 3
Professional installation by experienced local experts
This process allows us to adapt to homes with older construction methods, uneven walls, timber movement, or non-standard openings. Colour matching also helps preserve the original appearance of the property, allowing security screens to blend into the home rather than stand out visually.
Can Crimsafe Be Added to Existing Timber or Aluminium Windows?
In many cases, yes. Existing timber and aluminium windows can often support Crimsafe security screens without needing full replacement windows. However, the condition of the existing frame matters.
During a consultation, Securelux checks the structural condition of the frame, lock compatibility, installation access, and fastening suitability. If the windows are structurally sound, security screens can usually be added directly.
Timber windows are extremely common across older Queensland homes and can work very well with modern security screens when handled correctly. The installation process may involve additional reinforcement, careful frame preparation, and protective sealing around fastening points.
Older aluminium windows are also adaptable for security screen installation. Depending on the design, Securelux may recommend hinged screens, sliding screen systems, fixed security panels, or Safe-S-Cape systems for emergency egress.
What If Your Window Openings Are Uneven or Non-Standard?
Uneven openings are extremely common in older homes. Over decades, houses naturally shift slightly due to settling, weather, and structural movement. This means many older windows and doors are no longer perfectly square.
Fortunately, custom security screen installation accounts for this. Professional installers do not assume every opening is level or standard. Instead, every opening is individually measured and manufactured to suit the exact dimensions of the property.
Incorrect measurements can create visible gaps, poor locking performance, water ingress issues, and difficulty opening or closing screens. Securelux uses precise measuring processes to ensure each product fits correctly and performs properly over the long term.
Queensland homeowners also want security without sacrificing airflow. This is one reason Crimsafe remains popular across Brisbane and the Gold Coast. Security screens allow homeowners to keep windows and doors open for ventilation while maintaining a strong physical barrier between the home and outside access points.

Will installing screens damage my old timber frames?

Do I need council approval for a heritage-listed home?
Some heritage-listed or character homes need approval for changes to the outside of the house, so check with your local council first. We can give you product details to support an application.
Can the screens match my home's colours?
Yes. Frames come in a range of colours, so we can match or blend them with your window frames and trims.

We can usually measure within 24-48 hours of your call, and selected products can be installed in as little as 2 weeks.* Arched and custom shapes may take longer, and we'll give you a date with your quote.
