Waterproof Wall Mounted Mailbox

Buying Guide

Locking wall mount mailboxes are the secure solution to the fatal flaw of regular wall mounted mailboxes. Without a lock, these mailboxes make it possible for anyone to approach your home and take your mail.

These mailboxes are keyed so that only you and your mail carrier have access, ensuring your post is secure and confidential at all times.

You’ll find locking wall mounted mailboxes in a variety of designs so you can perfectly accent the exterior of your home. Cream or beige siding looks gorgeous with a stainless steel mailbox, while brown or red brick benefits from the contrast of a modern teak design.

Factors such as weather conditions and location can all influence the type of metal you should choose for your locking wall-mount mailbox. A person living in a rainy climate would call for a different mailbox material compared to one in a sunny country. Moreover, a neighborhood where mail theft is common would require a much sturdier and resilient metal construction, such as galvanized steel.

Conversely, lightweight metals like aluminum are easier to assemble and are budget-friendly. Aluminum is also fairly durable and suitable for areas with mild climates. That said, locking wall-mount mailboxes made out of aluminum may rust when not treated for water resistance, especially during rainy seasons.

A much better alternative for wet and snowy climates is cast aluminum. Unlike traditional aluminum, this material is heavy and won’t rust when exposed to outdoor elements such as rain, sleet, snow, as well as heat.

If you’re on the lookout for a contemporary-style mailbox to go with your modern exterior, look no further than brushed stainless steel. Known for its impressive durability, this metal can hold up well to the elements while remaining in pristine condition for a long time.
