Wood Siding

Wood Siding

This is an outer layer of wooden boards that protects your home from the weather. You can paint or stain it to match your style. It needs regular care to stop rot and keep bugs away.

Origin

The word siding comes from the Old English word sidan which means the side or flank of an object. Builders have used wood to cover homes for thousands of years.

How you'll see it used

  • Your home inspection report flags a section of wood lap siding near the back deck that has soft spots and needs replacing before it rots the framing.
  • A local exterior painter gives you a quote of 4,500 dollars to scrape, prime, and repaint your cedar wood siding to protect it from the summer sun.

What Wood Siding Is

Wood siding is the classic outer layer of many American homes. Builders cut real wood into boards or shingles to cover your exterior walls. This layer blocks wind, rain, and snow from getting inside. Wood naturally insulates your home better than thin vinyl. It helps keep your house cooler in the summer and warmer in the winter. It also breathes well, which lets trapped moisture escape from your walls.

You'll usually see woods like cedar, pine, or redwood. Cedar and redwood are very popular because they naturally fight off rot and bugs. Pine is cheaper but needs more care. You can find wood siding in a few common styles:

  • Lap siding: Long boards that overlap each other horizontally to shed water.
  • Board and batten: Wide vertical boards with narrow wood strips covering the seams.
  • Shingles or shakes: Small wooden pieces that overlap to give a rustic, textured look.

Why It Matters To You

Good siding does more than just look nice. It acts as the first line of defense for your house. If your siding fails, water can reach the wood framing underneath. This causes massive damage over time. Wood siding also adds major curb appeal. Many buyers love the rich, warm look of real wood. You can easily change its color with a fresh coat of paint or stain.

If a stray baseball cracks a vinyl panel, you might have to replace a huge section. With wood, a carpenter can just cut out the bad piece and drop in a new one.

What To Watch For

Real wood requires real work. Unlike vinyl or brick, wood can rot if it stays wet. You need to inspect your siding every year. Walk around your house and look for peeling paint or dark stains. Press gently on the wood near the ground or under your gutters. If the wood feels soft or spongy, you have rot.

Keep dirt away from your wood. Make sure your siding sits at least 6 inches above the soil or mulch. If the wood touches the ground, it acts like a sponge and pulls up water, which leads to fast rot.

You also need to watch out for bugs. Termites and carpenter bees love to chew on untreated wood. Woodpeckers might also drill holes in your siding to find bugs. If you spot tiny holes or piles of sawdust, you should read our Pest Control guide to stop the damage early.

Maintenance And Costs

To keep wood siding alive, you must seal it from the weather. You need to repaint or restain your home every 3 to 7 years. Sun and rain will break down the finish over time. If you wait too long, the wood will crack and warp. You should also wash your siding once a year. Use a garden hose and a soft brush to remove dirt and mold. Don't use a high pressure washer. A strong blast of water can strip the paint right off the wood and push moisture deep into the boards.

Replacing wood siding isn't cheap. For a typical home, new wood siding costs between 10,000 and 25,000 dollars. The exact price depends on the type of wood and the size of your house. Local labor rates also change the final bill. If you only need to fix a few rotten boards, a handyman might charge 300 to 800 dollars. Prices and ranges vary by region, so always get a few quotes.

Frequently asked

How long does wood siding last?

With proper care, wood siding can last 20 to 40 years, and sometimes even longer. You just have to keep it painted or stained so water cannot soak into the boards. If you ignore maintenance, it can rot in less than a decade.

Can I pressure wash my wood siding?

You should avoid using a high pressure washer on real wood. The intense spray can easily gouge the soft wood and force water behind the boards where it causes hidden rot. It is much safer to use a regular garden hose and a soft bristle brush.
