Crown Molding

Crown molding delivers the highest ROI of any trim upgrade, instantly signaling a finished, high-end room. Pre-primed MDF crown from Home Depot costs just $1-3 per linear foot, so a standard 12x14 room needs about 52 linear feet — totaling $52-$156 in materials. The key challenge is cutting accurate compound angles on inside and outside corners; using a coping saw with patience produces tighter, more forgiving joints than mitering both pieces, outperforming #6's simpler approach. Flexible caulk fills small gaps seamlessly. Once painted, even imperfect joints become invisible. This architectural detail transforms a space from basic to bespoke, proving that a $100 investment can yield a $1,000 visual upgrade.
