Despite the postal sector’s current difficulties, we will continue to use a physical mail system for the foreseeable future.

Mail is more crucial than ever as more businesses go online and consumers like you demand faster deliveries. Because of this, many homeowners decide to mount their mailboxes directly on the exterior of their homes.

Drilling into vinyl siding will cause it to fracture and expose your home to water damage. Vinyl siding is not intended to be drilled into. Using vinyl siding S hooks or adhesive is the safest way to hang anything from vinyl siding.

It is advisable to mount your mailbox with S hooks because it is too hefty to be supported by glue. With the correct tools, you can install your mailbox in your house regardless of the material it is constructed of.

Steps To Install A Mailbox On Vinyl Siding

Select A Mailbox

You will initially need a mailbox that you can mount to your siding! If you plan to use it for mail, the most crucial factor is whether it complies with basic electrical other restrictions. With a stylish box, you have additional alternatives.

Prepare Your Area

Your mailbox can be installed in a few different ways. The siding needs to be ready first. You could hang it from your home’s soffit if you’re feeling inventive.

It would help to double-check the rules to ensure this option is permitted before choosing it to support your mailbox; otherwise, you might need to add more support. You might also utilize a hanging mailbox for something else.

Mark The Points On The Wall

Hold your mailbox up against the wall where it will be displayed to indicate the locations of the holes on the wall. To ensure that the holes align equally, hold the mailbox straight.

If you’re mounting the mailbox on brick, make sure the holes are in the center of the brick rather than on the mortar, which will lead to constant chipping and make the holes bigger and less stable.

Drill Holes

Once you have marked the location of the mailbox on the wall or siding, you are all set to drill the holes. So, you can mount the mailbox on vinyl siding appropriately and firmly. After drilling the hole, clean the area of debris and dust.

If drilling through vinyl or steel siding, equip a cordless drill with a normal wood bit larger than the screw. Use a carbide or masonry bit if the siding is a composite or concrete-fiber product. Do not raise, lower, or tilt the drill in any direction. Only drill through the siding on the exterior.

Use A Super Adhesive

Use super glue or industrial-level adhesive to anchor and insert them into the drill holes. Using glue is essential to keep your mailbox firm and strengthened in the same position for a long time. The reason is that you cannot drill a hole in your walls or siding every second day. Otherwise, it might lead to cracks.

Place Mailbox

Insert the mounting screws after holding the mailbox in place to align the mounting holes with the S-hook holes in your vinyl siding. Using a screwdriver, attach the nuts to the screws’ opposite ends and tighten them.

Is It Possible To Add a Mailbox To the Vinyl Siding Without Drilling Holes?

If your home has vinyl siding, you can avoid drilling by utilizing vinyl siding hooks instead of the more popular method of fastening window boxes to the side of the house with screws. Once you slide the hooks into the siding’s seam, you’re ready to hang whatever you want.

Vinyl siding can also be covered using Command strips. They don’t do any harm and are easy to use. They leave no residue behind after application and removal. Once you have mounted your mailbox, you are all set to put your mail in this box.

It is not difficult to install a mailbox, especially if you follow the guidelines and instructions that come along with your mailbox.
