How to Choose the Right Wood for Your Fence
Choose cedar for the best balance of durability and cost ($20-25 per foot installed) – it lasts 18-22 years in Twin Falls and resists rot naturally. Choose pressure-treated pine if budget is tight ($18-22 per foot) but expect more maintenance and 12-15 year lifespan. Choose redwood for premium appearance and 25+ year lifespan but pay $28-35 per foot. Avoid untreated pine or fir entirely – they rot in 5-8 years in Idaho weather.
At Twin Falls Fencing, we’ve installed every type of wood fence you can imagine. Cedar makes up about 60% of our wood fence installations. There’s a reason for that. It performs well in Idaho’s brutal climate without costing as much as premium options.
Let’s break down the actual differences between wood types, what drives cost and longevity, and how to match wood selection to your specific situation.
Cedar: The Default Choice for Good Reason
Western Red Cedar costs $20-25 per linear foot installed for 6-foot privacy fence in Twin Falls. That’s middle-range pricing but you get natural rot resistance and insect resistance built in.
The oils in cedar repel insects and resist decay. This matters tremendously in Idaho where moisture and temperature swings create perfect conditions for rot. Cedar handles it better than most woods without chemical treatment.
Cedar lasts 18-22 years with proper maintenance. Seal or stain it every 2-3 years and it hits the upper end of that range. Skip maintenance and you’re looking at 12-15 years. Still better than pine.
The wood is relatively soft and easy to work with. Cuts clean. Holds fasteners well. Doesn’t split as readily as harder woods. Installation goes smoothly which keeps labor costs reasonable.
Cedar weathers to silver-gray if left untreated. Some people like that natural weathered look. Most prefer to maintain the original color with sealant or stain. Either way works.
Weight matters for installation. Cedar is lighter than pressure-treated pine. A crew can move cedar boards around all day without wearing out. Sounds minor but it affects installation efficiency and cost.
According to the American Woodworking Association, cedar’s natural oils and resistance to moisture make it one of the most durable choices for outdoor applications in varying climates.
We stock several grades of cedar at Twin Falls Fencing. The difference shows up in knots and grain patterns, not performance. Lower grades have more knots but last just as long as clear grades. You’re paying for appearance, not durability.
Pressure-Treated Pine: Budget-Friendly But Higher Maintenance
Pressure-treated pine runs $18-22 per foot installed. That’s $2-4 per foot less than cedar. On a 150-foot fence, you save $300-600 choosing pine over cedar.
The treatment forces preservatives deep into the wood under pressure. This protects against rot and insects. Modern treatments use copper-based preservatives, not arsenic like old pressure-treated lumber.
Pine lasts 12-15 years in Twin Falls with consistent maintenance. The treatment handles rot fairly well. The problem is pine itself is softer and less stable than cedar. It warps and twists more as it dries.
Treated pine arrives wet from the treatment process. It needs to dry before you can seal or stain it effectively. That means 3-6 months of weathering. The fence looks rough during this period and some boards will warp as they dry.
Maintenance requirements are higher than cedar. Plan on sealing annually for the first few years, then every 2 years after that. Skip this and the boards crack and split much faster than cedar would.
The green or brown tint from treatment chemicals fades over time. You can stain over it but the undertone shows through lighter stains. Dark stains hide it better.
Weight is significant. Wet treated pine is heavy. Really heavy. Installation takes longer and requires more effort. This adds to labor costs even though material costs less. As covered in our article on cheapest fence options, the lowest material cost doesn’t always mean lowest total cost.
We install a lot of pressure-treated pine for customers watching budget closely. It works fine if you commit to the maintenance schedule. The savings are real if you do the work yourself.
Redwood: Premium Performance at Premium Price
Redwood costs $28-35 per foot installed. That’s 40-75% more than cedar. You’re paying for superior rot resistance and longer lifespan.
Redwood lasts 25-30 years in Twin Falls climate with proper maintenance. The natural tannins resist decay even better than cedar oils. Redwood fence boards from the 1970s are still performing in some local properties.
The wood is beautiful. Rich red-brown color that darkens over time. Tight grain. Minimal knots in higher grades. If appearance is priority, redwood delivers.
Redwood is stable. It doesn’t warp or twist like pine. Boards stay straight as they age. This matters for privacy fences where gaps between boards ruin the whole point.
Maintenance is similar to cedar. Seal every 2-3 years to maintain color and maximize lifespan. The wood performs well even without sealing but appearance suffers.
Availability is limited. Most redwood comes from California and Oregon. Shipping to Idaho adds cost. We can get it but lead times are longer than cedar or pine.
Environmental concerns exist with redwood. Old-growth redwood is heavily restricted. Most available redwood now comes from managed second-growth forests. Still, some customers prefer to avoid it for conservation reasons.
We install redwood when customers want the absolute best and budget supports it. Usually this is for front yards, pool enclosures, or properties where the fence is a design feature rather than just functional barrier.
Spruce and Fir: Avoid These for Fencing
Spruce and fir are cheap. Really cheap. $12-16 per foot installed. There’s a reason.
These woods rot fast in Idaho. We’re talking 5-8 years even with good maintenance. They don’t have natural rot resistance. They don’t hold treatment chemicals as well as pine. They’re just not suitable for fencing in our climate.
The boards warp badly as they dry. Knots are common and they often fall out, leaving holes in your fence. Splits and cracks develop within the first year.
We don’t recommend spruce or fir for fencing in Twin Falls. The money you save upfront gets spent on replacement in less than half the time a proper fence should last. False economy.
Wood Grade and Quality Differences
Clear grade has no knots or minimal small knots. It’s the most expensive. You’re paying for appearance. Performance is identical to lower grades of the same wood species.
Standard grade has knots throughout. The boards are structurally sound but not as pretty. This is what most residential fencing uses. Good balance of cost and appearance.
Economy grade has more knots, including larger ones, and more color variation. Still structurally adequate but looks rough. Fine for property boundaries where appearance doesn’t matter.
The grade affects price by $2-5 per foot. Clear cedar costs $25-28 per foot while standard cedar runs $20-23 per foot. Same wood, same durability, different looks.
At Twin Falls Fencing, we show customers actual boards from different grades. Most people choose standard grade. The knots add character and the cost savings are significant over 150+ linear feet.
Heartwood vs Sapwood
Heartwood is the dark center of the tree. It’s denser and more rot-resistant. This is what you want for fence posts especially.
Sapwood is the lighter outer wood. It’s less dense and rots faster. It absorbs treatment chemicals better than heartwood though, which is why pressure-treated lumber includes both.
For cedar and redwood, heartwood matters. That’s where the natural oils and tannins concentrate. All-heart grades cost more but last longer. Standard grades mix heartwood and sapwood.
Fence boards can be mixed heartwood and sapwood without major issues. Posts should be heartwood or pressure-treated for maximum ground contact resistance.
Kiln-Dried vs Green Wood
Kiln-dried lumber is dried in controlled environment to specific moisture content. It’s stable. Doesn’t warp as much. More expensive.
Green wood is freshly cut with high moisture content. It’s cheaper but shrinks and warps as it dries. This is standard for most fencing lumber.
Cedar and redwood are typically kiln-dried or air-dried before sale. They’re stable enough to use immediately. The boards stay straight.
Pressure-treated pine is always wet from treatment. You’re getting green wood no matter what. It will dry and move. Plan for some warping and twisting in the first year.
The stability difference affects fence appearance. Kiln-dried boards maintain tight gaps. Green boards create uneven gaps as they dry. Both work functionally but look different.
Cost Analysis by Wood Type
For a 150-foot privacy fence installed:
Pressure-treated pine: $2,700-3,300 installation plus $500-800 maintenance over 15 years before replacement. Total: $3,200-4,100 over 15 years.
Cedar: $3,000-3,750 installation plus $400-600 maintenance over 20 years. Total: $3,400-4,350 over 20 years.
Redwood: $4,200-5,250 installation plus $400-600 maintenance over 25 years. Total: $4,600-5,850 over 25 years.
Pine looks cheaper but you replace it sooner. Cedar costs more upfront but lasts longer. Redwood costs the most but lasts longest. The per-year cost tells the real story.
Pine: $213-273 per year. Cedar: $170-218 per year. Redwood: $184-234 per year.
Cedar wins on annual cost. Redwood wins on lowest maintenance hassle. Pine wins only on immediate out-of-pocket expense.
Climate Considerations for Twin Falls
Idaho’s temperature swings from -10°F to 95°F stress wood significantly. The expansion and contraction cycles cause splitting and checking.
Cedar handles this better than pine. The cellular structure flexes without failing. Pine is more rigid and cracks develop faster.
UV exposure at 3,800 feet elevation is intense. 220+ sunny days per year. This breaks down lignin in wood and causes graying. All wood types experience this but cedar maintains structural integrity better than pine as it weathers.
Freeze-thaw cycles hit 40-60 times per winter. Water in wood cracks freezes, expands, and makes cracks bigger. Cedar’s natural oils help resist water absorption. Pine absorbs more moisture and suffers more freeze-thaw damage.
Wind load is constant. Spring gusts over 50 mph. Stronger wood handles this better. Cedar and redwood are denser than pine and resist wind damage more effectively. Our fence lifespan article covers how Twin Falls weather affects different materials.
Matching Wood Choice to Fence Location
Front yards benefit from better wood. Cedar or redwood. This is the visible fence. It represents your property. Worth paying more for appearance and durability.
Backyards can use standard cedar or even treated pine if budget is tight. Function matters more than appearance. The fence contains kids and dogs. It doesn’t need to be beautiful.
Property line fences where neighbors share cost often use treated pine by agreement. Lowest common denominator on shared expenses. It works for boundary marking.
Pool enclosures need durable wood. High moisture environment from splashing. Cedar or redwood handle this better than pine. The constant wet-dry cycles destroy pine faster.
Near sprinklers or drainage areas, avoid pine entirely. Use cedar minimum. Constant moisture exposure overwhelms pine’s treatment and rot starts within 5 years.
Posts vs Boards: Different Requirements
Fence posts need maximum rot resistance. They’re in ground contact. Moisture is constant. This is where fences fail first.
Use pressure-treated posts for all wood types. Even cedar and redwood benefit from treatment when buried. The treatment adds 10+ years to post life.
Posts should be heartwood if not treated. Sapwood rots fast in ground contact. All-heart cedar or redwood posts last 15-20 years without treatment.
We set all posts with 6 inches of gravel at the bottom regardless of wood type. This drainage prevents water pooling and dramatically extends post life. Many installers skip this step. We don’t.
Boards can be lower grade than posts. They’re above ground. No ground contact means rot resistance matters less. Standard grade cedar boards on treated posts work great.
Sustainability and Environmental Impact
Cedar comes from managed forests in Pacific Northwest. It’s renewable. Harvest practices have improved significantly over last 30 years. Most cedar is now sustainably sourced.
Pressure-treated pine uses chemicals. Modern copper-based treatments are safer than old arsenic treatments but they’re still chemicals leaching into soil over time. The wood itself is renewable though.
Redwood raises conservation concerns. Old-growth redwood is protected. Second-growth redwood is harvested but some environmental groups oppose any redwood harvest. Check certifications if this matters to you.
All wood fencing is more environmentally friendly than vinyl from a renewability standpoint. Trees grow back. Vinyl is petroleum-based plastic. The trade-off is vinyl lasts longer so you replace it less often.
Common Wood Selection Mistakes
Choosing based only on upfront cost. Pine saves $300-600 on installation but costs more over time through higher maintenance and earlier replacement.
Using untreated wood for posts. The posts rot at ground level in 8-12 years. Treated posts last 20-25 years. The extra $5-8 per post is worth it.
Mixing wood types visibly. Cedar fence with pine gate looks mismatched. The colors and grain are different. Stick with one wood type for visible sections.
Buying lowest grade to save money on highly visible fencing. Economy grade cedar on the front yard looks rough. Standard grade costs $200-300 more on a typical fence and looks significantly better.
Not factoring in maintenance time and cost. If you won’t maintain it, cedar is worth the extra $2-3 per foot over pine. Lower maintenance requirements over the fence’s life justify the cost difference.
What Twin Falls Fencing Recommends
For most residential applications, we recommend standard grade cedar. It balances cost, durability, and appearance better than other options.
If budget is extremely tight, pressure-treated pine works but only if you commit to annual maintenance for first 3 years, then every 2 years after. We make this maintenance requirement very clear upfront.
For premium applications where appearance is critical, clear grade cedar or redwood. Front yards, pool enclosures, properties where fencing is part of the overall landscape design.
Always use treated posts regardless of board type. The posts determine fence longevity. This is not the place to save money.
We stock clear and standard grade cedar, plus treated posts, year-round. Pine is readily available. Redwood requires advance order but we can get it with 2-3 week lead time.
Questions to Ask Before Deciding
How long do you plan to live in this house? If it’s 5-7 years, treated pine might be fine. If it’s 15-20 years, cedar makes more sense financially.
Will you maintain the fence properly? Be honest. If the answer is no, cedar tolerates neglect better than pine.
Is appearance important for this fence? Front yard or highly visible area? Pay for better wood. Back property line where nobody sees it? Treated pine works.
What’s your total budget including maintenance? Don’t just compare installation costs. Factor in the 2-3 year maintenance cycle over the fence’s expected life.
Do you have environmental preferences? If avoiding chemicals matters, cedar or redwood are better choices than treated pine. If conservation concerns matter, avoid redwood.
Installation Quality Matters More Than Wood Type
The best wood poorly installed fails early. Average wood properly installed lasts its full expected life.
Post depth matters enormously. We go 30-36 inches deep in Twin Falls. Frost line hits 24 inches. Going deeper prevents frost heave. Many installers go only 24 inches and posts shift within 5 years.
Drainage at post bases extends life by 10+ years. Six inches of gravel. Every post. No exceptions. We see rot fail posts set directly in clay soil or concrete without drainage.
Proper spacing prevents sag and maintains appearance. We run posts 8 feet apart. Some installers go 10 feet to save posts. The fence sags within 3-5 years.
Quality fasteners prevent premature failure. Stainless steel screws or hot-dipped galvanized. Cheap fasteners rust and fail in 5-7 years. The boards are still good but the connections fail.
At Twin Falls Fencing, we install every wood fence the same way regardless of wood type. Proper technique matters more than wood selection for long-term performance.
