Cobblestone is not a type of rock but a term for a mosaic or rock laid down as a surface. It used to be made from the closest available stone but now can be made from nearly any hard rock, as machining has made shaping the stone much easier and cheaper.

Professionally done brick repointing can last 20 to 30 years, sometimes longer. However, the exact lifespan depends on several factors, including the quality of the mortar, the skill of the mason, and exposure to weather. If you live in an area with harsh weather or frequent freeze-thaw cycles, you may need to repoint more often. Repointing that is done as a DIY project may only last 10 to 15 years. It's time to repoint when you notice signs of mortar failure, such as crumbling or missing mortar, holes, or vines growing between the bricks. Regular inspections can help you catch these issues early.

No, you don’t need to soak the brick before cutting it by hand. In fact, cutting a wet brick can make it harder to see your score lines and may cause the chisel to slip. Soaking is sometimes used with power tools to reduce dust, but for hand-cutting, it’s best to work with dry bricks for better control and visibility.

Yes, it is usually possible to repair a damaged brick mailbox. A professional brick mason or masonry contractor can perform the repairs. They can assess the damage, provide an estimate, and help you determine if the repair is worthwhile based on the mailbox's value and the extent of the damage. The repair process may involve sourcing replacement bricks and mortar. Damaged bricks can be cut out and replaced, or the mortar joints can be cut out and retucked. It's important to note that the new mortar may differ in color from the original. If the mailbox insert itself is damaged, it can typically be cut out and replaced as well. If your brick mailbox has been completely destroyed, you should check with your local building code enforcement office before rebuilding, as some areas do not allow brick mailboxes due to the potential hazard they pose to drivers.
