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.

Avoid toxic chemicals that can leach into nearby lawns, as well as household ingredients like vinegar that can ruin paint and sealants. Instead, look for a very light detergent or a dedicated exterior siding cleaner. In a pinch, you can use a basic dish or laundry soap, but we suggest sticking with a dedicated cleaner.

If your siding is struggling with algae or moss, which indicates moisture issues, look for an outdoor cleaner that’s specifically designed to clear moss and algae stains. This is also a sign that you need to seal your clapboard against further problems.

You should use a siding nail gun for siding installation, but if you don’t have one you can use a framing nailer instead, if the nails are long enough to firmly attach to the clapboard siding. However, framing requires longer nails that join lumber together. In that instance, siding nails will not be enough.

Hardie board is more expensive than vinyl siding. Vinyl siding costs $3 to $12 per square foot, on average, with cost skewing toward the lower end of that range. Hardie board siding costs $7 to $18 per square foot, depending on the style, color, and trim. However, it lasts twice as long and often looks nicer, meaning you’ll see a higher bump in your home value and greater curb appeal from Hardie board.
