FAQ

What materials are letterboxes and house numbers typically made from?+

You’ll find a diverse range of materials here, including cast iron for classic styles, stainless steel for durability and weather resistance, brushed aluminium for a contemporary look, and various types of plastic and composite materials offering cost-effective options.

How do I measure for a new letterbox?+

Measure the width and height of your existing letterbox opening carefully. Add approximately 1cm to each dimension to allow for a snug fit. Ensure you also account for any mounting plate thickness when determining the overall size requirements.

What sort of fixings are usually included with house numbers?+

Most house numbers come with screws and wall plugs suitable for standard brick or plasterboard walls. However, always check the product description to ensure compatibility with your wall type – you may need specialist fixings.

Can I paint letterboxes and house numbers?+

Yes, many metal letterboxes and house numbers can be painted using exterior-grade paints designed for metal surfaces. Always apply a primer first for better adhesion and durability, protecting against the elements.

How do I ensure my house number is securely mounted?+

Use appropriate wall fixings for your wall type – consider using a plasterboard adhesive filler before screwing in to improve grip. Ensure screws are long enough to penetrate adequately into the wall's structure for maximum security.

What’s the best way to clean cast iron letterboxes?+

Cast iron can be cleaned with warm water and mild soap, followed by a dry cloth. Avoid using abrasive cleaners or scouring pads which could damage the finish. Applying a wax occasionally will help maintain its shine.

Are stainless steel house numbers rust-proof?+

Stainless steel is inherently resistant to rust, however, it’s important to keep them clean and free of debris. Regular cleaning with a damp cloth and mild detergent will help preserve their appearance and corrosion resistance.

Can I install a letterbox in a cavity wall?+

Installing a letterbox directly into a cavity wall is generally not recommended due to potential water ingress issues. Consider using a suitable sealant and weather stripping around the edges for added protection, but consult with a professional installer if unsure.

What size should my house number be?+

House numbers should typically be at least 10cm high for good visibility from most distances. Check local planning regulations as some areas may have specific requirements regarding size and placement of house numbers.

Are there any specific considerations for installing house numbers on different materials?+

When mounting on brick, use appropriate masonry fixings. For rendering or plasterboard, consider using wall plugs and adhesive fillers to ensure a secure attachment – always check product specifications for compatibility.
