Staining and sealing is the single best thing you can do to make a Houston wood fence last — it blocks the moisture that causes rot and the UV that turns wood silver-gray and brittle. The job is straightforward: clean the fence, let it dry fully, then apply a penetrating semi-transparent stain-sealer with a sprayer, brush, or roller and back-brush it in. The most common mistake is staining wood that is still damp or brand-new, so timing the dry-out is as important as the stain itself.
What you'll need
- A pump sprayer or pressure washer
- A stiff scrub brush
- A paint sprayer, roller, or stain brush
- A paint tray
- Drop cloths or cardboard
- Painters tape
- Gloves and eye protection
Recommended parts & supplies
- Exterior wood fence stain and sealer — oil or hybrid penetrating stain holds up best in humidity
- Wood cleaner / brightener — removes gray, mildew, and mill glaze before staining
- Stain brush for back-brushing — works the stain into the grain after spraying
- Exterior deck screws — to snug up any loose boards before you stain

Step by step
- 1
Pick the right weather window
You want two dry days in a row with no rain in the forecast, moderate temperature, and out of direct blazing sun. In Houston that usually means spring or fall, or an early start before the afternoon heat. Avoid staining in high humidity right after rain — the wood needs to be dry to accept the finish.

Clean the fence and kill the mildew
Mix a wood cleaner or brightener and scrub the fence, or use a pressure washer on a low, wide setting held well back so you do not gouge the soft wood. This strips off the gray oxidized layer, dirt, and the black mildew that Houston humidity grows. Work top to bottom and rinse thoroughly.
- 3
Let it dry completely — this is the key step
Wet wood will not absorb stain, and sealing in trapped moisture leads to peeling and rot. Give the fence at least 48 hours of dry weather to fully dry out after cleaning. A quick test: sprinkle water on the wood — if it soaks in rather than beading, the wood is dry and thirsty enough to stain. Brand-new pressure-treated pickets may need to weather for several weeks to months before they will take stain.

Make repairs and mask what you want to protect
Now, while the wood is bare, drive in any popped nails, replace cracked pickets, and snug up loose boards with fresh exterior screws. Lay drop cloths or cardboard along the base to protect grass and patios, and tape off anything you do not want stained.

Apply the stain and back-brush it in
Stir the stain well and apply a thin, even coat with a sprayer, roller, or brush, working in sections a few boards wide from top to bottom to keep a wet edge. Right after applying, back-brush each section — drag a brush over it to push the stain into the grain and even out drips and laps. Do not let stain puddle; wipe any excess. Stain both sides if you can reach them.
- 6
Let it cure and check coverage
Let the first coat dry per the can. Most penetrating stains need only one coat; if the wood soaked it up unevenly, a light second coat evens the color. Keep sprinklers off it and stay off it in the rain until fully cured. Plan to reapply every two to three years in Houston, since our sun and humidity are hard on any finish.
When to call a pro
Staining is a very DIY-friendly job, but call a pro if the fence is so far gone that boards are rotting, cupping, or crumbling — no stain will save wood that has already failed, and you are better off replacing sections. Also consider hiring out very tall, very long, or two-story-slope fences where ladders and hundreds of feet of boards make it a punishing job to do by hand. If you find widespread rot while cleaning, get a repair-versus-replace assessment before you invest a weekend in staining wood that is near the end of its life.
