What's it cost? A gallon can range from $17 to more than $100. Higher-cost paints have better-quality ingredients, which help ensure long-term durability.
Hire a pro or DIY? Anyone can brush on paint. But doing an entire house is a big job. If you don't have patience for prep or a yen to climb ladders, hire it out.
How much care? When siding and trim look dingy, a wash with detergent, a scrub brush, and a garden hose can restore a paint job's good looks.
When to paint? The best time is when temperatures remain between 50 and 90 degrees and the humidity is low. In these conditions, paint should brush out and dry properly.
How long will it last? That depends on the paint and what it's applied to. Two coats of top-quality paint over primed wood might last 10 to 15 years. Two coats on stucco can hold up significantly longer.
