To clean painted aluminum siding, use a mixture of mild detergent and water applied with a soft brush or sponge. Rinse thoroughly with a garden hose to remove soap residue. For stubborn stains, cleaning aluminum siding with a power washer on a low-pressure setting can be effective. But avoid using high pressure, which could damage the paint.

Composite siding is very resistant to warping that can affect some other sidings. Because of its composition, this siding doesn’t have the same risks of moisture damage that can cause rotting, buckling, and warping. Composite material doesn’t warp in high temperatures the way some kinds of vinyl siding can.

That said, composite siding is not entirely immune from moisture damage. It should still be properly installed so that moisture can properly drain from behind the siding, and protected by eaves and clean gutter so the siding doesn’t get repeatedly soaked by rain, which could lead to damage.

Professional installers typically recommend caulking between siding boards, but it depends on the material. With Hardie board and fiber cement siding, manufacturers don't recommend adding caulk because it can trap moisture in the joints or discourage flexibility in fluctuating temperatures. Consult your local siding contractor about caulking best practices before adding any to your home’s exterior.

You should plan to stain or refinish your home's cedar siding every three to seven years to maintain its appearance and provide maximum protection, though some estimates suggest a range of four to six years. The exact frequency depends on several factors, including your local climate, exposure to severe weather like direct sunlight, rain, and wind, the quality of the initial stain application, the type of stain used, and the overall condition and quality of the wood.

For homes in harsh climates with high humidity and significant sun exposure, you should plan on staining as often as every three years, while those in milder locations may only need to do so every seven years. For the longest-lasting protection in particularly harsh climates, consider using an opaque stain.

If you are looking for a lower-maintenance alternative, you might consider vinyl or aluminum siding. While the initial installation cost can be higher, they do not require as much upkeep and can offer more value over time, especially in areas with excessive rainfall or high humidity.
