Mountain Brook is built on large, heavily wooded lots where mature tree canopies drop debris onto rooflines year-round and root systems press against crawlspace walls and masonry foundations. The housing stock is dominated by large single-family homes, many built in the mid-twentieth century with brick exteriors and crawlspace foundations that now sit on decades of red clay movement. Neighborhoods like Crestline, Brookwood Forest, and Mountain Brook Village contain homes where original masonry, roofing, and crawlspace construction has never been updated. That combination of age, tree coverage, and clay soil makes moisture intrusion and masonry deterioration the two most common construction problems here.
