A deck is a horizontal surface, and that changes everything
Walls shed water. Deck boards hold it, take foot traffic and face the sky all day. That's why a deck finish wears faster than wall paint and why re-staining is a recurring job. The cost of each round depends less on the stain itself than on the state of the wood and how much work it takes to get it ready.
What the Cedar Rapids station lists
NOAA's engineering weather data for Cedar Rapids lists a 50-year basic wind speed of 90 mph (3-second gust at 33 feet), a 100-year rainfall rate of 3.3 inches per hour and about 54 freeze-thaw cycles in an average year. In an average year at Cedar Rapids, NOAA counts about 355 hours with the wet-bulb temperature above 73°F and about 1,124 hours above 67°F. Those are the station's figures, quoted as NOAA gives them.
Two of them matter most for a deck. Water that soaks into a worn board and then freezes works the grain open, and the freeze-thaw count is the number of times, in an average year, that happens. The humid-hour counts describe warm, damp hours, which slow drying after washing and between coats.
Size, railings and stairs
Square footage of the deck floor is the starting point, but it's not the whole picture. Railings, balusters and stairs take far longer per foot than open boards, because every face and edge is brushed by hand. A small deck with lots of railing can take as long as a large plain one. Ask for the floor, railings and stairs to be priced as separate items.
Cleaning and stripping
Old finish has to be dealt with before new stain can soak in. A deck with sound, faded semi-transparent stain may need only a cleaner and a rinse. A deck with peeling solid stain or old paint needs stripping, which is slower, uses more product and may take more than one pass. The condition of what's there now is often the biggest single factor in the price.
Sanding and raised grain
Washing and stripping can raise the grain and leave fuzzy wood. Sanding the floor smooth, and catching splinters on rails, adds time but helps the new stain go on evenly and feel better underfoot.
Board and fastener repairs
Cracked, cupped or soft boards should be replaced before staining, and popped nails reset or swapped for screws. Freeze-thaw cycles open checks in the wood, so a deck that's gone a few winters without a finish may need more of this. Ask how replacement boards will be priced, and whether new boards will be left to weather before staining, since fresh lumber doesn't always take stain evenly.
Stain type
- Transparent and semi-transparent stains soak in, show the grain and wear away rather than peel. They're quicker to renew next time.
- Solid-color stains hide the grain and look more like paint. They cover worn or mismatched boards but can peel and need more prep when renewed.
Switching from solid to semi-transparent usually means stripping back to bare wood, which adds cost.
Drying time and rain days
Wood must be dry before stain goes on, and stain must be dry before rain. After washing, a deck may need a day or more to dry, longer during damp spells. A crew may lose days waiting for the right weather, and some price that risk in. Ask how rain is handled and how long the deck will be out of use.
Access and protection
Plants under the deck, furniture to move, siding next to the boards and windows above all need covering. A ground-level deck is easier than a raised one where the crew needs ladders to reach the outside of rails.
