Some cracking in bricks is normal, such as when a foundation settles. Keep a watchful eye though, and alarm bells should start ringing if new cracks appear or existing cracks lengthen or widen. Temperature changes, moisture, and structural loading can all contribute to cracks in bricks either starting or getting worse.

The best tool for drilling into brick or mortar is a rotary hammer drill which is a large hammer drill with low rotation speed and high torque. Regular drills with a hammer function are also excellent tools for drilling into brick when the diameter of the hole is 1/2 inch or less. It might be possible to drill into brick with a standard drill if you’re only drilling a very small hole, but note that masonry work will put a lot of wear on a standard drill, and the tool may not be strong enough to get through brick.

Painted exterior brick does not usually need sealing. Brick is a porous material, so you don’t want to apply a sealant that could trap moisture inside the bricks and cause erosion and structural damage. The risk of moisture-induced damage after sealing is higher in colder climates where trapped moisture can expand if it freezes. On the other hand, it makes sense to seal really old brick or kitchen backsplashes, where moisture from cooking can weaken the brick.

If your old bricks are in decent condition and you have the space to store them where they’ll be protected from the elements, keeping old bricks is often worthwhile. You’d spend anywhere from $70 to a few hundred dollars to have them removed from your property, in which case you won’t be able to use them for future projects. Holding on to old bricks in good condition means you can use them later for other DIY projects, potentially saving yourself some money on disposal and new materials down the road.
