Step 1
Clean Off Growth And Old Finish
The deck is washed to clear algae, mildew, grey surface fiber, and any peeling finish that would stop new stain from bonding.
Staining a shaded deck is a different job than staining a sunny one. The prep matters more, the drying takes longer, and skipping either is why so many deck finishes fail in a single season.

It stays wet longer after rain, grows algae rather than simply bleaching out, and holds moisture deep in the boards well after the surface feels dry to the touch. All three of those work against a stain finish.
That is why the prep is most of this job. The deck gets cleaned to remove growth and failing finish, brightened to reopen the grain, and then given real time to dry down to the right moisture level. Stain applied over a damp shaded deck cannot penetrate, so it sits on the surface and peels off in sheets by the following summer.
Once the wood is genuinely ready, we stain and seal. The finish penetrates instead of sitting on top, the color stays even across the boards, and the sealed surface sheds water rather than absorbing it, which is what actually buys you years between refinishes.
Cleaning, brightening, and a real drying window are what let stain penetrate on a deck that never gets full sun.
A sealed deck stops absorbing the moisture that shaded boards otherwise sit in, which slows cupping, cracking, and rot.
Sealed wood gives algae far less to grip. Under canopy that is the difference between cleaning every year and every few years.
Properly prepped boards take stain evenly, instead of the blotchy look you get when some areas were still damp or still dirty.
Step 1
The deck is washed to clear algae, mildew, grey surface fiber, and any peeling finish that would stop new stain from bonding.
Step 2
A wood brightener neutralizes the cleaner, restores natural tone, and reopens the grain so the stain can soak in.
Step 3
Shaded decks need longer than open ones. We schedule the stain for when the boards are actually ready, not on a fixed calendar.
Step 4
Stain is applied evenly and worked into the wood, then sealed so the color and the water protection last.
My deck is under heavy trees. Does that change the stain choice?
It changes the schedule more than the product. Shaded decks need a longer drying window before staining, and they benefit from a finish with good mildew resistance since they stay damp longer than a deck in full sun.
How long will the stain last on a shaded deck?
Usually two to three years for the walking surface. Shade cuts UV damage, which helps, but the extra moisture works the other way. Railings and vertical surfaces almost always outlast the floor.
Can you stain over the existing finish?
Only if the existing finish is sound and compatible. If it is peeling or flaking, which is common on shaded decks, it has to come off first or the new stain will fail along with it.
What if it rains after you stain?
We watch the forecast and schedule around it, because fresh stain needs dry time to set. If weather moves in unexpectedly we would rather reschedule than apply a finish that will not cure properly.
