A deck is mostly edges
A deck looks like a flat floor, but most of the staining time goes into the parts that aren't flat: balusters, top rails, stair stringers, the ends of boards and the gaps between them. That's why two decks with the same floor area can get very different quotes. This guide goes through what a painter or stain crew looks at, so you can see why one bid differs from another. It quotes no prices.
What weighs on a deck here
Stain on a deck faces more than paint on a wall does, because the boards lie flat under the sun and hold water. The figures here are NOAA's, from two stations:
- The current climate normals for Little Rock's Adams Field airport average 76.4 days a year with a high of 90°F or more, and give about 3,164.8 heating degree days and 1,988.9 cooling degree days in an average year.
- The engineering weather data for Little Rock AFB, near Little Rock, list about 42 freeze-thaw cycles in an average year and a 100-year rainfall rate of 3.8 inches per hour, along with a 50-year basic wind speed of 90 mph (3-second gust at 33 feet).
Freeze-thaw cycles matter to a deck because water soaked into end grain and checks expands as it freezes. A stain that keeps water out of the wood helps; one that has worn thin lets it in. Hot days matter at the time of application: stain put onto boards baking in direct sun can flash dry and leave lap marks.
The cost drivers
Size and layout
Floor area is the starting point. Multi-level decks, built-in benches, planter boxes and long stair runs all add time. A deck high off the ground may need ladders or staging to reach the outside of the rim and the posts.
Railings
Railings are often the biggest single line. Square balusters have four faces each; a long run of them can take longer than the floor. Ask whether the price covers both sides of every baluster and the underside of the top rail.
The old finish
What's on the deck now drives the prep:
- Weathered bare wood: a cleaner and a rinse may be enough before stain.
- Worn semi-transparent stain: usually cleaned and brightened, sometimes lightly sanded.
- Peeling solid stain or paint: has to be stripped or sanded back to sound material, the slowest and dustiest case.
- Mixed: some boards replaced over the years can take stain differently from the old ones.
Board and fastener repair
Split, cupped or soft boards should be replaced before staining, and popped nails reset or swapped for screws. A crew should list the repairs in the quote and say whether they're included or extra. Structural problems, such as soft joists or loose ledger connections, aren't a staining matter; ask the painter to point them out so you can have them looked at separately.
Stain choice
- Clear and toner finishes show the grain and need renewing sooner.
- Semi-transparent stains add color while showing grain.
- Solid stains hide the grain and cover mismatched boards, but can peel on walking surfaces if applied too thick.
The product class affects both the price today and how soon the next re-coat comes due. Our deck and fence staining page compares them.
Drying days
Wood has to be dry before stain goes on. After washing or stripping, many crews wait a day or more, and rain resets the clock. Ask how many dry days the job needs, and how the schedule handles rain.
Access and protection
Plants, siding and windows next to the deck need covering from cleaner and stain. Furniture and grills have to move. Tight spaces under a low deck are slow to work in.
Comparing quotes
Put the quotes side by side and check that each covers the same scope:
- floor, railings, stairs and skirting, or only some of them;
- cleaning method, and whether stripping is included;
- repairs, listed individually;
- the stain product and how many coats;
- protection of the house and landscaping;
- what happens if it rains between coats.
The lowest quote often leaves out the railings' inner faces, the stair risers or the stripping. Our pricing guide explains other reasons bids differ.
Keeping the next job smaller
Sweep the deck often, keep planters off the boards, and rinse off pollen and grit. Look each spring at the boards that get the most sun and the stair treads: when water stops beading on them, the finish is wearing. Catching that early can mean a light clean and one coat instead of a full strip.
