    How the Process Works
    If you’ve placed your order online and requested installation services, one of our team
    members will contact you to arrange a convenient installation date.

    For phone or email orders, we will take your details, agree on an installation date, and send a confirmation email with payment instructions for a 50% deposit.

    A day before installation, our technician will confirm the time and provide a one-hour arrival window.

    If you have any special requirements—such as access details, installation location, or requests to be contacted when the installer is on their way—please inform us via phone or email.

    Please note that installation dates may vary between 1-2 business days or 1-2 business
    weeks depending on our workload at the time.

    Fit For Your Home?

    ✅ Best For:

    A stylish, premium-looking solution for homes without a front fence. Perfect for modern facades, driveways, or new builds where you want a neat, freestanding letterbox with solid footing — without the cost of brickwork.

    📍 Mounting Surface:

    Installed on a custom concrete base slab
    Fixed in place using industrial-strength adhesive (no visible bolts or brackets)
    Sits directly on driveways, gravel strips, lawns, or garden beds

    🔧 Installation Time:

    Typically 1.5 to 2 hours, including slab curing and secure mounting
    📏 Height & Compliance:

    Installed at 900mm–1200mm above ground, compliant with Australia Post guidelines
    We ensure the box is level, aligned with the curb, and positioned for easy mail access

    🧱 Durability & Strength:

    Fibro cement construction offers weather resistance and low maintenance
    Concrete base provides excellent stability, even in windy or high-traffic areas
    Secured with heavy-duty adhesive for long-term durability

    👍 Pros:

    ✅ Modern, clean appearance – no visible fixings
    ✅ Doesn’t require fencing or posts
    ✅ Freestanding but solidly anchored
    ✅ Suitable for all residential mail types
    ✅ Great for front lawns, gardens, or driveway edges

    ⚠️ Considerations:

    ⛔ Requires concrete slab, which adds to installation time and cost
    ⛔ Not easily moved once installed
    ⛔ More expensive than basic post-mounted options
    ⛔ Removal of an old letterbox is not included (can be quoted separately)

    💬 Tip:

    If you want the look of a brick-in letterbox without the build, this is a smart alternative. It’s a great way to add curb appeal and function — especially in estates or homes with open front yards.
