Wood playground equipment lasts 10 to 20 years, and reaching the top of that range requires resealing every two to three years for the life of the structure. Commercial steel and plastic equipment lasts 15 to 20 years or more with a fraction of that attention, which is why most schools and parks specify wood only where the natural look is the point.
The honest answer is that wood's lifespan depends less on the wood than on whether anyone keeps up with it. Here's what determines how long it lasts, what the upkeep actually involves, and how it compares to the alternatives for a commercial site.
What determines how long wood lasts
Four variables set the range, and only one of them is about the timber itself.
Species matters most at purchase. Cedar and redwood contain natural oils that resist rot and insects, so they outlast pine and other softwoods even before treatment. Pressure-treated lumber closes some of that gap chemically.
Climate does the damage. Humid and rainy regions accelerate rot, dry heat warps and checks the grain, and freeze-thaw cycles open cracks that widen every season.
Treatment and sealing extend life substantially. Most commercial wood equipment arrives pre-treated against rot and insects, and a weatherproof sealant applied on schedule is what keeps moisture out of the grain.
Traffic accelerates everything. A school structure serving several recesses a day wears handholds and steps far faster than a lightly used site, and worn wood is where splintering starts.
Ground contact is the usual failure point. Posts rot where they meet soil or standing water, often while the rest of the structure still looks sound, which makes footing detail more important on wood than on steel.
The maintenance commitment wood requires
Wood upkeep is recurring rather than occasional, and it's the part most buyers underestimate.
Reseal every two to three years without exception. A missed cycle lets moisture into the grain, and once rot starts inside a component, you're replacing it rather than treating it.
Inspect annually at minimum, and more often at high-traffic sites. Look for splinters, cracks, soft spots at ground level, and hardware that has worked loose as the wood shrinks and swells through seasonal cycles.
Clean the surfaces on a schedule too. Dirt, sand, and mildew hold moisture against the wood and accelerate deterioration, and a gentle wash with soap and water is enough.
Repair promptly rather than at the next budget cycle. A loose board or cracked rail is inexpensive to fix and expensive to ignore, since damage spreads along the grain.
Safety issues specific to wood
Wood fails in ways metal and plastic don't, and the failure modes are what drive the inspection schedule.
Splinters are the most common complaint and the easiest to prevent. Sanding and resealing worn handholds, steps, and rails handles it, but a structure that has gone several years without attention can splinter across many surfaces at once.
Hardware loosening is the more serious concern. Wood expands and contracts with moisture and temperature, which works bolts loose over time, so torque checks on wood equipment need to happen more often than on steel.
Older equipment deserves a closer look. Some wood playground structures installed before the mid-2000s used lumber treated with chromated copper arsenate, an arsenic-based preservative that was phased out of residential and playground use. If you've inherited an older wood playground, it's worth confirming what the lumber was treated with.
Have a Certified Playground Safety Inspector (CPSI) assess any wood structure past the 10-year mark. Internal rot isn't visible from outside, and a professional assessment tells you whether you're looking at repairs or replacement.
How wood compares for a commercial site
Three alternatives outperform wood on durability and upkeep for high-traffic public use.
Powder-coated galvanized steel is the strongest structural option. Play structures built on steel posts resist rot entirely, need no resealing, and the finish protects the metal underneath as long as it stays intact.
Ultraviolet-stabilized plastic handles decks, panels, and slides. Rotationally molded plastic components don't splinter, don't rot, resist fading, and clean with soap and water.
Composite materials are the compromise worth knowing about. Wood fibers combined with synthetic binders give something close to the look of timber without the sealing schedule, though cost and availability vary.
Most commercial structures now combine materials rather than choosing one. Steel frames with plastic decks and climbing components is the common configuration because each material handles the job it's best at.
When wood is the right choice
Wood still makes sense in specific situations, and it's worth being clear about which.
Natural and nature-themed playgrounds are the strongest case. Where the design intent is a play space that reads as part of the landscape, natural playground equipment using timber and natural forms achieves something steel can't.
Lower-traffic sites can support it too. A church playground used on weekends wears far more slowly than a school site, which makes the sealing cycle easier to keep up with.
The deciding question is who does the maintenance. If you have a grounds crew with capacity and a recurring budget line for sealing, wood can serve well for two decades. If you don't, specify steel and plastic and spend the maintenance savings elsewhere.
