Many people who want to replace their letterboxes in Australia look for one that’s the same as their current one. While finding the exact match is ideal, sometimes getting it can be a difficult task. What’s more, replacing a letterbox can be costly depending on the type. The cost ranges between $50 and $1,000. 

Replacing a Letterbox

There are various types of letterboxes available in a vast range of materials and designs. For example, letterboxes designed for wooden doors are made to standard sizes. However, you can get variations in a similar model from the manufacturer.

It’s worth noting that the sand casting process also varies and this means dimensional differences can happen between various manufacturing processes. Some letterboxes come with a handle that’s also used as a door knocker.

You can also choose to fit a flap cover at the inner part of the door which gives it a neater look. If you’ll be using solid brass screws you should create full-length pilot holes. This is because these screws are usually soft. Avoid using a power screwdriver to protect the screw slot from damage. 

Measuring Your Door for the Letterbox

Work from the outer part of your door and measure the cross rail depth. With a pencil, make a mark at the center in two places. These should be approximately 35mm apart.

Step 1

Create a line in between the two marks.

Step 2

Measure the cross rail’s width and identify the center point. Create a short vertical line over the one you had already drawn.

Step 3

Place your letterbox over the meeting points of the lines and mark where you’ll fix the bolts on each side. 

Fitting the Letterbox

This task becomes easier when you use a power jigsaw to cut off the opening of your letterbox. Fitting a cover over your internal letterbox opening and keep puffs away is easy. 

Step 1

Begin by drilling holes where you’ll fix the bolts. They should be larger than a bolt shank’s diameter.

Step 2

Use a pencil to mark where you’ll cut the opening. This should be slightly larger than the hinged area of your letterbox. 

Step 3

Create a hole at each corner of the opening. Use a drill bit that’s big enough to produce a hole where you can place a pad saw blade measuring approximately 8mm.

Step 4

Place the pad saw blade in one of the corner holes and cut carefully around the rectangle throughout the door.

Step 5

After creating the opening, use a mallet and a narrow chisel to create recesses for the hinge-pin. Clean the opening corners and smooth the edges out using abrasive paper. 

Step 6

Fit your letterbox in position using the supplied nuts. If you notice that the bolts are longer than door thickness, you can easily shorten them using a hacksaw. 

Letterboxes are still in use in the modern-day. You may want to upgrade yours to give it a more sophisticated look. This can be an easy DIY project but you can still have it done by a professional. Doing it yourself is cheaper but a professional will do it better.
