Cedar shows up across most of our range — gazebos, greenhouses, swing sets, cubby houses — and one of the most common questions we get is how much upkeep it actually needs. The honest answer: less than most woods, but not zero. Here's what actually matters.
Why Cedar Doesn't Need Chemical Treatment
Unlike pine or fir, which typically need to be pressure-treated with chemical preservatives to resist rot and insects, cedar carries natural oils that do this job on their own. That's why our cedar structures aren't pressure-treated — the wood itself is naturally resistant to decay and insect damage from the day it's built. That built-in resistance is real, but it's not permanent immunity: over years of sun and rain exposure, those natural oils gradually deplete from the surface layer of the wood, which is where ongoing care comes in.
The Weathering Decision: Silver-Grey or Stained
You have two legitimate paths with cedar, and neither is wrong. Left alone, cedar weathers naturally to a soft, silvery grey over a year or two — a look a lot of people actually prefer, and it costs you nothing in maintenance beyond the general care below. The alternative is keeping the warmer, freshly built look with a semi-transparent exterior stain or sealer, which needs to be reapplied roughly every one to two years to stay effective. Neither path is more "correct" than the other; it's a look you're choosing, not a structural requirement.
How Often to Reseal
If you've chosen the stained route, one to two years is the general rule, but your actual climate matters more than the calendar. Harsh sun, coastal salt air, or a spot with heavy weather exposure all shorten that window. A simple test: if water no longer beads on the surface and instead soaks in, the existing coat has broken down and it's time to reseal, regardless of exactly how long it's been.
A Simple Seasonal Checklist
Spring is the natural time for a full look-over: check and re-tighten any hardware that's loosened over winter, and clear out anything that accumulated in gutters or roof seams. Through summer, keep an eye on the sunniest-facing side of the structure, which will always fade or dry out faster than shaded sides. In fall, clear leaves and debris before they pile up on roof panels and in corners, since trapped wet leaves are one of the few things that can cause localized rot even on cedar. In winter, on gazebos and other roofed structures, don't let heavy snow accumulate on the roof without checking it — clearing it periodically reduces the load the structure has to carry.
What Not to Do
Skip the pressure washer, or at least skip the high setting. A powerful, close-range spray can strip the wood's natural surface oils and even gouge softer grain, doing more harm than the dirt it's removing. A garden hose and a soft brush handle routine cleaning fine. Avoid harsh chemical cleaners for the same reason — they can strip finish and natural oils faster than normal weathering would on its own.
Why the Hardware Matters Too
Cedar structures are built with galvanized or stainless hardware rather than standard steel, specifically so fasteners don't rust and streak the wood around them the way ordinary screws or bolts would over time. That's built in from the factory, but it's still worth a periodic check: wood naturally expands and contracts with humidity and temperature, and hardware that was snug when the structure was built can work slightly loose after a season or two of that movement. A quick pass with a screwdriver or wrench once or twice a year keeps everything tight without needing to replace anything.
Cleaning Between Reseals
You don't need to wait for a full reseal to clean the surface. A mild soap-and-water solution and a soft-bristle brush handles everyday dirt, pollen, and mildew spotting without touching the wood's natural oils the way a pressure washer or harsh chemical cleaner can. Rinse thoroughly with a garden hose afterward, and let the wood dry completely — at least a full day in good weather — before applying any new stain or sealer, since sealing over damp wood traps moisture underneath rather than protecting the surface.
Normal Wear vs. a Warranty Issue
It's worth knowing the difference before you assume something's gone wrong. Natural weathering, gradual color change, and small surface checking (the fine cracks that appear as wood expands and contracts) are all normal and expected in outdoor cedar — not defects. What is covered under Gaddy Gear's 1-year limited warranty is an actual defect in materials or workmanship from the date of delivery. If you're not sure which you're looking at, email contact@gaddygear.com with a photo and we'll tell you plainly which side of that line it falls on — full terms are on our Warranty Information page.
Adjusting for Your Climate
The general guidance above holds everywhere, but the details shift with climate. In hot, dry regions, UV exposure is the bigger threat — south- and west-facing surfaces will fade and dry out fastest, so check those sides first when deciding whether it's time to reseal. In humid or coastal areas, moisture and salt air are the bigger concern, which usually means resealing closer to the one-year mark rather than two, and paying extra attention to keeping debris out of joints and seams where damp material can sit against the wood. In colder regions with real snow load, the main seasonal task shifts to keeping roofs clear rather than worrying much about UV at all. None of this changes the core routine, it just changes which part of it deserves the most attention where you live.
Where This Applies
This care routine applies across every cedar structure we carry — our wood gazebos, our greenhouses, and our swing sets and cubby houses. Put a few minutes into it once or twice a year and cedar rewards you by simply outlasting most other outdoor wood options with the least effort.
