Not wrapping a house before installing siding can lead to moisture intrusion, rot, mold, and even higher energy bills. Older houses may have siding installed without wrap underneath, so it’s a good idea to add a wrap layer when it comes time to replace old siding to prevent potential damage from water intrusion—local codes may even require it, so check with your municipal building authority. 

Brick and stone are the most durable and longest-lasting siding materials, often lasting for 100 years or more with proper maintenance. Copper is another material known to last over 100 years, though it can develop a greenish patina over time. Zinc is a metal siding that can last 80-100 years. While these options are the most expensive, they offer superior value and longevity. For a more affordable yet durable choice, stucco can last 50 to 80 years in dry climates. Fiber cement siding is another excellent middle ground, offering a lifespan of 50 years or more with low maintenance at a lower cost than stone or brick.

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.

Though vinyl siding is affordable, the material may not last as long or look as good as other siding materials. For example, wood siding has a beautiful, natural appearance but requires much more maintenance to keep your siding looking as good as new. 

Fiber cement siding is another alternative that mimics the appearance of wood siding. Like vinyl siding, fiber cement is a low-maintenance material, but it does come at a higher price and is heavier and more difficult to install. Weigh the pros and cons of all siding materials before you decide on the best option for your home.
