Wood Fences: A Comprehensive Guide to Natural Beauty and Privacy

A wood fence is still the most popular way to get privacy and curb appeal in Chicago. Wood is warm, easy to customize, and costs less up front than most metal, vinyl or composite fences. But any fence in the midwest has to survive freeze-thaw cycles, heavy snow, road salt along the alleys and humid summers. The wood you choose and the way the fence is built decide whether it lasts 8 years or 20.

This guide covers what we’ve learned building wood fences across Chicago since 1975: which wood holds up best, the most popular styles, how long each option lasts, and how a fence should be built for our climate. If you’d rather skip ahead to options and pricing, see our wood fence installation in Chicago page.

Key Takeaways

• Western Red Cedar is the best all-around wood for fences in the midwest.
• Pressure-treated pine is the budget choice and the right material for posts set in the ground.
• A well-built cedar fence lasts about 15–20 years. Pressure-treated pine lasts about 10–15 years.
• Most wood fences fail at the posts, so post depth and post material matter more than board choice.
• Residential fences are limited to 6 feet, and front-yard fences are limited to 54 inches if they’re more than 20% solid.

What Is the Best Wood for a Fence in The Midwest?

For most homes, Western Red Cedar is the best wood for a fence. Its heartwood contains natural oils that resist rot and insects, it swells and shrinks less than pine as the seasons change, and it takes stain evenly. Pressure-treated pine is the lower-cost alternative, and redwood is a premium option. Here’s how the main fence woods compare.

Western Red Cedar

Cedar is the wood we install on most residential and commercial projects. It’s lightweight, stable and naturally resistant to decay, so boards stay straighter through wet springs and dry winters. Left unfinished, cedar weathers to a soft silver-gray. Sealed or stained every 2–3 years, it keeps its warm reddish-brown color. Cedar costs more than pine, but it needs fewer board replacements over the life of the fence.

Best for: privacy fences, board-on-board, shadowbox, horizontal slat, and any fence you plan to stain.

Pressure-Treated Pine

Pressure-treated (PT) pine is southern yellow pine infused with preservatives that protect it from rot and insects. It’s the most affordable fence wood and very strong. That’s why ground-contact-rated PT lumber is the standard for wood fence posts, even on cedar fences. The trade-offs: PT boards arrive wet, shrink and can twist or check (crack along the grain) as they dry, and they look more uniform and less refined than cedar. Let new PT wood dry for several weeks before staining.

Best for: budget privacy fences, posts and rails, and utility fencing.

Redwood

Redwood heartwood is highly resistant to decay and insects, with rich color and tight grain. It’s also the most expensive option in the Midwest because it ships from the West Coast, and lead times can be longer. Redwood is a good choice for showpiece front-yard fences and gates, but most Chicago homeowners get similar performance from cedar for less.

Best for: decorative fences, gates and accent sections.

Cypress and Spruce

Cypress has natural decay resistance and is common in the Southeast but rarely stocked in the midwest. Spruce and untreated whitewood pine are the cheapest boards you’ll find at big-box stores, but they have little natural rot resistance. In our climate, we don’t recommend them for any part of a fence that stays damp or touches the ground.

Cedar vs. Pressure-Treated Fence: Which Should You Choose?

Choose cedar if you want a better-looking fence that stays straighter, takes stain beautifully and needs fewer repairs over 15–20 years. Choose pressure-treated pine if the budget is tight, the fence is mainly functional (a side yard or utility area), or you plan to paint it a solid color.

Many of the best Chicago fences use both: ground-contact pressure-treated or galvanized steel posts for strength below grade, with cedar rails and boards above. You get the post strength of treated lumber and the looks and stability of cedar where it shows.

Can You Build a Fence with Untreated Wood?

You can, but only with the right wood in the right place. Naturally rot-resistant woods like cedar and redwood are sold untreated and work well for boards, rails and pickets because their oils protect them. Untreated pine, spruce or fir won’t last. Once they stay damp through a winter, they can start rotting within a few years.

The rule we follow: anything set in the ground or in contact with soil should be ground-contact pressure-treated lumber or galvanized steel, never untreated wood. Keep boards about 2 inches above the soil so they dry out between rains and snowmelt.

If you’re trying to save on materials, pressure-treated pine is a safer budget choice than untreated softwood.

Popular Wood Fence Styles

Solid Privacy Fence (Stockade or Dog-Ear)

Boards set edge to edge for full privacy. It’s the most common backyard fence and the most budget-friendly privacy style. Dog-ear boards have clipped top corners. Flat-top boards give a cleaner look.

Board-on-Board Fence

Boards overlap on both sides of the rails, so the fence stays fully private even after the wood shrinks in winter. If privacy is the goal, a board-on-board cedar fence is the style we install most often in Chicago backyards, and it’s a great choice for pets and busy alleys.

Shadowbox Fence

Boards alternate on each side of the rail, so the fence looks finished from both sides and lets air pass through. A good “good neighbor” fence for shared property lines.

Horizontal Slat Fence

Horizontal cedar boards with tight or spaced gaps for a modern look. Popular with newer homes, rooftop decks and contemporary renovations. Horizontal fences need closer post spacing or a stiffener so long boards don’t sag.

Picket Fence

Spaced vertical pickets for front yards and gardens, with flat, pointed or scalloped tops. Open picket spacing is usually needed to meet Chicago’s front-yard rule (see the permits section below).

Lattice-Top and Decorative Fences

A solid fence topped with a lattice panel adds height, light and texture. Post caps, trim boards and arched tops finish the look on any style.

How Long Does a Wood Fence Last?

A well-built wood fence typically lasts 15–20 years or more in Chicago if it’s cedar, and 10–15 years if it’s pressure-treated pine. Untreated softwood fences often fail in 5–8 years. The difference comes down to four things:

• Post installation. Posts are the first part of a fence to fail. Posts set too shallow get pushed up by frost (frost heave) and start to lean within a few winters.
• Ground contact. Boards and rails that touch soil, mulch or snow piles stay wet and rot first.
• Finish. Sealing or staining every 2–3 years slows moisture damage, cracking and graying.
• Maintenance. Fixing a loose board or a leaning post early prevents the rest of the section from failing.

Our guides on wood fence maintenance, how to repair a wood fence and the best fence stain and sealer cover each of these in detail.

How a Wood Fence Is Built (Posts, Rails and Boards)

Every wood fence has the same three parts: posts, rails and boards (or pickets). How each part is built decides how well the fence handles Chicago weather.

1. Layout and Utility Locates

The fence line is measured against your plat of survey and marked, including gates and grade changes. In Illinois, JULIE (811) must be contacted before digging so buried utility lines can be marked.

2. Posts

Posts are typically 4×4 ground-contact pressure-treated lumber or galvanized steel, spaced 6–8 feet apart. In the Chicago area, posts should be set in concrete deep enough to resist frost heave, about 42 inches. Many DIY guides recommend 2 feet, which isn’t deep enough here. The top of the concrete should be sloped away from the post so water doesn’t pool against the wood.

3. Rails

Horizontal rails (usually 2x4s) connect the posts and carry the boards. A 6-foot fence should have three rails to resist warping. Fences in the City of Chicago must be built to withstand at least 30 pounds per square foot of wind pressure, so rail and post spacing matter on solid privacy fences.

4. Boards or Pickets

Boards are fastened to the rails with exterior-grade, corrosion-resistant fasteners (hot-dip galvanized or stainless steel), because standard nails rust and stain cedar. Boards should sit about 2 inches above the ground.

5. Gates

Gates carry the most stress on any fence. A well-built wood gate has a diagonal brace, heavy-duty hinges and a gate post set as deep as or deeper than the line posts. Wide driveway gates can also be automated.

6. Finishing

Cedar can be sealed or stained as soon as it’s installed and dry. Pressure-treated wood should dry for several weeks first. Sealing all cut ends during installation helps stop moisture from wicking into the wood.

Wood Fence Permits and Height Rules 

As a top rated fence company in Chicago we know the city regulations and our fences are built under a Department of Buildings permit, and most suburbs require their own fence permit. In the City of Chicago:

• Residential fences are limited to 6 feet in height, measured from the lowest ground within 12 inches of the fence. Posts can extend up to 6 inches higher.
• In a residential front setback, a fence more than 20% solid is limited to 54 inches.
• Barbed or razor wire must be listed on the permit and can’t be lower than 7 feet.

Each suburb sets its own heights, setbacks and fees. For more detail, see our guide to fence laws in Chicago or the City’s fence permit terms.

Wood Fences for Commercial Properties

Wood isn’t just for backyards. Cedar privacy screens, dumpster enclosures and perimeter fences are common on restaurants, apartment buildings, churches and HOA properties, where they hide service areas without the industrial look of chain link. For commercial work, we recommend steel or ground-contact posts, three rails, and heavy-duty gate hardware built for daily use. See our dumpster enclosures for gated cedar and steel enclosure options.
