Cedar lap siding is one of the most beloved natural cladding choices in America, prized for its warm grain, rich color, and timeless curb appeal. Also called bevel or clapboard siding, it consists of long horizontal boards installed in overlapping courses that shed water and give homes that classic, handcrafted look. Beyond its beauty, cedar offers natural resistance to rot and insects, making it a durable choice when properly maintained. But cedar is a natural product with real upkeep demands and a premium price, so it pays to understand the costs, grades, installation, and maintenance before you commit. This guide covers everything you need to know.
What Is Cedar Lap Siding?
Lap siding, sometimes called bevel or clapboard, is made of boards that are thicker on one edge than the other, so each course overlaps the one below it. This overlap sheds rainwater and creates the distinctive shadow lines that give homes such depth and character. Cedar is the wood of choice for premium lap siding because it is naturally rich in oils that resist decay and insects, it is dimensionally stable (resisting warping and cupping), and it takes stain and paint beautifully. Western Red Cedar is the most common species in the U.S., valued for its straight grain, warm reddish tones, and workability.
Grades and Styles
Cedar siding comes in several grades and finishes that affect both appearance and price:
- Clear grade: Knot-free, uniform, and the most expensive, ideal for a refined, upscale look, especially when stained to show the grain.
- Knotty grade: More affordable, with visible knots that give a rustic, natural character popular on cabins and craftsman homes.
- Smooth vs. rough-sawn face: Smooth suits a clean painted look; rough-sawn holds stain well and reads more rustic.
- Bevel, Dutch lap, and shiplap profiles: Different edge profiles change the shadow lines and overall style.
What Cedar Lap Siding Costs
Cedar is a premium material, and pricing reflects that. Typical ranges:
- Material only: $3 to $9 per square foot depending on grade and profile, with clear grade at the top.
- Installed cost: $6 to $15 per square foot including labor.
- Average home (1,500 sq ft of siding): roughly $9,000 to $22,500 installed.
Compared with vinyl or fiber cement, cedar sits at the higher end, and the ongoing maintenance adds to lifetime cost. However, many homeowners consider the natural beauty and the ability to refinish cedar over decades well worth the premium, especially on architecturally significant homes.
The Pros of Cedar Lap Siding
- Natural beauty: Few materials match cedar’s warm grain and rich tones.
- Durability: Natural oils resist rot and insects, and quality cedar can last 30 to 40 years or more with care.
- Insulating value: Wood offers modestly better natural insulation than vinyl.
- Refinishable: Unlike vinyl, cedar can be re-stained or repainted to change color or refresh its look.
- Eco-friendly: A renewable, biodegradable natural material.
- Repairable: Damaged boards can be replaced individually.
The Cons to Consider
Cedar is not maintenance-free, and that is its biggest drawback. To keep it looking good and lasting long, it must be re-stained or repainted every few years, which is an ongoing cost and effort. Left unfinished, cedar weathers to a silvery gray and, without protection, becomes vulnerable to moisture, rot, and insect damage over time. It is also more expensive upfront than vinyl or engineered options, and in wildfire-prone regions, wood siding raises fire concerns unless treated. Finally, cedar can be susceptible to moisture problems if installed incorrectly without proper flashing, house wrap, and ventilation. For homeowners unwilling to keep up with periodic refinishing, low-maintenance alternatives may be a better fit.
Installation Basics
Proper installation is essential to cedar’s longevity. The wall should have a weather-resistant barrier (house wrap) and, ideally, a rainscreen gap that lets air circulate behind the siding so it can dry, preventing moisture-related rot. Boards are installed from the bottom up, each course overlapping the one below by roughly an inch, and fastened with corrosion-resistant stainless steel or hot-dipped galvanized nails, since ordinary nails react with cedar’s tannins and cause black staining. Careful flashing around windows, doors, and corners keeps water out. Pre-finishing the boards, including the back and edges, before installation greatly extends their life. Because getting these details right is critical, many homeowners hire experienced siding contractors rather than attempting cedar as a DIY project.
Finishing: Stain vs. Paint vs. Natural
How you finish cedar shapes both its look and its maintenance schedule:
- Semi-transparent stain: Shows the grain while adding protection; needs reapplication every 3 to 5 years.
- Solid stain: More opaque and longer-lasting than semi-transparent, hiding grain but protecting well.
- Paint: Offers the most protection and color options but can peel and requires prep when recoating.
- Natural weathering: Left untreated, cedar turns silvery gray; attractive to some but offers the least protection and shortest lifespan.
Whatever you choose, applying a quality finish and keeping up with reapplication is the single biggest factor in how long your cedar siding lasts and how good it looks.
Maintenance Over the Years
Cedar rewards regular attention. Wash the siding annually with a gentle cleaner and soft brush to remove dirt, mildew, and pollen, avoiding high-pressure washing that can gouge the soft wood. Inspect the finish each year and re-stain or repaint before the coating fails and bare wood is exposed. Check for and replace any cracked, split, or rotted boards promptly, and keep vegetation trimmed back so air can circulate and moisture does not linger against the siding. Clean gutters so overflow does not soak the boards. With this routine care, cedar lap siding can protect and beautify a home for decades, developing the kind of character that makes wood siding so cherished.
How Cedar Compares to Alternatives
It is worth weighing cedar against the materials homeowners commonly consider instead. Vinyl siding is far cheaper and essentially maintenance-free, but it cannot match cedar’s depth, warmth, or ability to be refinished, and it can look plastic up close. Fiber cement, including engineered products designed to mimic wood grain, offers excellent durability and fire resistance with less maintenance than real cedar, though it lacks the authentic character and cannot be stained to show natural grain. Engineered wood siding provides a wood look at a lower price and with more consistency than natural cedar, but it is still a manufactured product. Cedar’s distinct advantage is that it is the real thing: genuine wood with genuine grain that can be refinished and repaired indefinitely and that develops character over time. If authenticity and the ability to refinish matter most to you, cedar wins; if you prioritize low maintenance and cost, an engineered alternative may serve you better.
Protecting Against Moisture and Pests
Cedar’s natural oils give it good resistance to rot and insects, but that protection is not unlimited, and moisture management is the key to a long life. Proper installation with a rainscreen gap lets air circulate behind the boards so any water that gets in can dry, preventing the trapped moisture that leads to rot. Keep the bottom course of siding several inches above grade and away from splashing soil, direct downspouts away from walls, and trim shrubs and trees so they do not hold moisture against the wood. Inspect regularly for signs of trouble: dark staining, soft spots, or peeling finish signal water intrusion that should be addressed before it spreads. In regions with heavy insect pressure, keep the finish intact, since bare, weathered wood is more inviting to carpenter ants and termites than sealed, finished cedar. Diligent moisture and pest management, combined with a maintained finish, is what allows cedar siding to reach its full 30-to-40-year potential.
Cedar lap siding delivers a warmth and natural elegance that manufactured products struggle to imitate, rewarding homeowners willing to invest in its upkeep with decades of beauty and durability. Weigh the premium price and maintenance commitment against the unmatched curb appeal, install it with proper flashing and ventilation, and keep the finish fresh, and cedar will remain one of the most rewarding exterior choices you can make.
