Get matched with top siding pros in Berry, AL

Wood clapboard siding needs frequent sealing to keep it in top condition—likely every two to three years. A sealant helps protect it from both moisture and sunlight damage. Your weather and climate will affect how often you need to seal the siding, but the pros recommend sealing it every couple of years. More durable woods in milder climates may not need to be sealed quite as often.

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 can calculate the required square footage of siding you need by measuring the height and width of your home’s rectangular exterior walls. For the triangular-shaped gable walls, measure the height from the ground to the tallest gable point to make sure you have enough for good coverage. Once you have combined the totals for each wall, add another 10% to account for wasted materials. It’s also good to have extra siding on hand to tackle wood siding repair down the road.

The main differences between dutch lap versus clapboard siding have to do with their design and texture. Clapboard siding features flat, beveled planks stacked at a slight angle, offering a simple, traditional look. Dutch lap siding features a subtly concave surface along with a notch that creates a shadowed look between the boards. This eye-catching design often resembles wood grain and introduces a noticeable shadow line, making it more visually interesting compared to the simpler look of clapboard siding.
