Frequently Asked Questions (FAQs)
1. Are plastic mailbox posts good?
Plastic mailbox posts are a great choice because they are durable and resistant to rust. They are not prone to issues like rust, unlike metal mailboxes. However, plastic mailboxes may not be the best option for extremely hot climates. In such cases, aluminum or steel mailboxes are highly recommended.
2. Which is better metal or plastic mailboxes?
Both metal and plastic mailboxes have their advantages. Plastic mailboxes are naturally resistant to rust and relatively easy to maintain. However, they may not be suitable for climates with extreme heat. Metal mailboxes, such as cast aluminum and galvanized steel, are more durable and excellent at resisting rust.
3. Should a mailbox post be set in concrete?
While it is not necessary to set a mailbox post in concrete, doing so can increase the stability of the mailbox. To set a mailbox post in concrete, follow the instructions provided by the manufacturer for preparing and pouring the concrete around the post. Leave a few inches of the post above ground level.
4. Can I install a mailbox post without concrete?
Yes, it is possible to install a mailbox post without using concrete. One option is to use a no-dig ground anchor, which can be purchased online. This alternative method provides stability for the post without the need for concrete. It is a convenient option for those who prefer not to use concrete.
5. Should I get a plastic mailbox?
The choice between a plastic mailbox and a metal mailbox depends on personal preference and budget. Plastic mailboxes are generally more affordable than metal mailboxes. They are also easier to maintain in harsh weather conditions. However, metal mailboxes, such as aluminum, steel, or copper, offer more variety in styles and may have better curb appeal for some homeowners.
6. What mailbox won't rust?
Cast aluminum mailboxes are a good choice for homes located in wet climates or areas with harsh weather conditions. They are less likely to rust and require minimal maintenance. Aluminum mailboxes, especially those made of cast aluminum, offer durability and longevity without the worry of rusting.
