What drives the cost of each, realistic lifespans, and what our clay soil and Texas sun actually do to each material, from a crew that builds both.
Cedar costs less up front and can last 15 to 20+ years if the posts are done right and you stain it every few years. Composite costs more up front, skips the staining, and the boards themselves typically outlast cedar, but a fence is only as good as its posts, and in North Texas clay that's true for both materials. Here's the honest breakdown.
What drives the cost of each one
For both materials, most of the cost is the length of the run, the height, the posts and how they are set, the gates, and tearing out the old fence. The material then moves it from there:
- Cedar: the style (board-on-board uses more pickets than side-by-side), the height, a cap and trim, and whether the posts are new or reused. Replacing only the rails and pickets on sound posts is the smallest cedar job
- Composite: the brand and the system. Composite pricing varies a lot from one system to the next, and many use their own posts, rails and trim
A comparable composite fence costs more up front, often considerably, depending on the system. Composite's argument is that you buy back some of that gap over the years in stain you never have to apply. i30 Builders prices both side by side, in writing, after a site walk, and the price does not move unless the scope does.
How long each one actually lasts here
Cedar: with quality lumber, posts set in concrete and a stain every few years, a cedar privacy fence commonly lasts 15 to 20+ years in our area. Skip the maintenance and let sprinklers soak the bottom of the pickets, and it can look tired in half that time. Staining dramatically extends a cedar fence's life. We price staining per run, because how much an existing fence soaks up depends on its age and condition.
Composite: composite boards resist rot and insects and won't gray out the way bare cedar does. Manufacturers commonly warranty the boards themselves for 25 years or more. The honest caveat: those warranties cover the boards, not the posts or the workmanship, and around here, fences fail at the posts long before good boards give up.
The equalizer: whichever material you pick, the lifespan question is mostly a post question. Proper depth, concrete footings, and (optionally) galvanized steel posts matter more than the picket material.
What North Texas does to a fence
Clay soil movement. Rockwall County sits on expansive Blackland Prairie clay that swells when it rains and shrinks hard in August. That constant movement is what heaves shallow posts and turns straight fences into leaning ones, and it doesn't care whether the pickets are cedar or composite. It's why we dig proper footings and set every post in concrete.
Sun exposure. Texas sun is brutal on anything that faces south or west. Unstained cedar grays and dries out fast, which is why staining isn't just cosmetic here. Composite holds its color far better long-term; most products fade slightly in their first season and then stabilize.

Hard freezes. Freezes like February 2021 push frost into soil that's usually never frozen, and the freeze-thaw cycle works on any post that's set too shallow or has water pooling in the hole. Deep, properly drained concrete footings are the defense, again, for both materials.
Which one should you pick?
Cedar makes sense if you want the classic wood look, a lower upfront price, and easy repairs, a damaged cedar picket is a cheap swap, and staining every few years keeps it looking new. It's what most of our neighbors choose, and it's what we build most.
Composite makes sense if you plan to stay in the house long-term, never want to think about staining, and the upfront budget isn't the deciding factor. It's also worth a look if your HOA favors a uniform, low-maintenance appearance.
Either way, insist on the boring stuff: post depth, concrete, quality fasteners. That's what decides whether your fence is straight in year ten.
