Modern brick houses are really stick-built homes with a brick facade for aesthetic purposes only, so most have framing. With genuine brick construction, most homeowners install furring strips over the interior of the brick and then install drywall over those strips to cover the brick wall, so they don’t have traditional framing.

Yes, it is normal to see some minor hairline cracks in brick or mortar over time, often due to natural foundation settling. However, not all cracks are harmless. You should be concerned and contact a masonry professional for an inspection if you notice cracks that are getting wider or longer, or if new ones keep appearing. Other serious warning signs that can indicate significant structural or foundation damage include large vertical cracks (especially those that widen as they go up), stair-step cracks, L-shaped cracks, and deep horizontal cracks. Factors like temperature changes, moisture, and structural loading can also cause cracks to form or worsen.

Yes, but used or reclaimed bricks can be more brittle, cracked, or uneven than new bricks, so they’re harder to cut cleanly by hand. For that reason, you should take extra care when scoring and striking, and expect a higher chance of breakage. If a brick feels especially fragile, score deeper before attempting to split it.

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.
