Staining a deck runs $450 to $1,000 on average in 2026, by HomeGuide's national figures. Around Stamford, decks face snow, freeze and thaw, humid summers and, near the water, salt and wind, so the finish and the timing both matter.
Every dollar figure on this page is a national number published by HomeGuide for 2026. None of them is a quote from The Stamford Painters. Labor rates, paint costs and the state of your own walls and siding shift the real price. We last checked these figures in October 2026.
How much does it cost to stain a deck?
HomeGuide's national cost to stain a deck is $1.50 to $4 per square foot with a professional, or $450 to $1,000 for an average deck. HomeGuide's national average sits at $730.
| Deck size | National range, professional staining |
|---|---|
| 10 x 10 | $157 to $404 |
| 12 x 12 | $226 to $582 |
| 12 x 16 | $301 to $775 |
| 12 x 20 | $376 to $969 |
| 16 x 16 | $401 to $1,034 |
| 20 x 20 | $628 to $1,616 |
How the deck is prepared moves the price. Stain and seal alone runs $0.50 to $1.50 per square foot. Adding a power wash makes it $1.00 to $2.50, power sanding $2.00 to $4.00, and stripping an old finish $2.50 to $5.50. Railings add $4 to $12 per linear foot.
Should I paint or stain my deck?
On most deck floors in this area, stain beats paint. It soaks into the wood and wears away slowly, while paint forms a film on top, and on a floor that holds snow and puddles that film cracks and peels.
HomeGuide lists deck painting at $2 to $5 per square foot and gives deck paint a life of 10 to 15 years, compared with restaining every 2 to 3 years. That paint figure assumes the film stays whole, which on a flat deck through Connecticut freeze and thaw often does not happen. Paint does better on railings, posts and skirting than on the boards you walk on.
Solid or semi-transparent stain on an old deck?
Pick solid stain for an older, weathered deck, and semi-transparent for younger wood that is still in good shape. Solid stain hides grey, patched and mixed boards and blocks the most sun. Semi-transparent shows the grain, so it looks best on wood worth showing.
Solid stain can peel if it goes on thick or over damp wood. Semi-transparent stain fades over time instead of peeling, and a fresh coat goes on more easily.
How often does a deck need restaining?
HomeGuide's national figure is every 2 to 3 years. Boards in full sun wear faster than railings, and decks near the Sound may need it sooner. Each spring, sprinkle water on the boards. Water that sinks in rather than beading up means the deck is due.
Can you paint a deck that was stained, or stain one that was painted?
A previously stained deck can be painted or given solid stain once it is cleaned and sanded. The other direction is harder. A deck that was already painted cannot take stain until the paint is stripped or sanded off, because stain needs bare wood to soak into.
HomeGuide lists repainting a deck at $3 to $9 per square foot and strip, stain and seal at $2.50 to $5.50.
Why is my deck stain peeling after a year?
Deck stain peels after a year when it could not soak in. The wood was damp, dirty or still sealed by an older finish, or the stain went on too heavy and dried as a film on the surface.
Snowmelt and rain then work under that film through the winter and lift it. To fix it, take the deck back to bare wood by stripping or sanding, let it dry out, and stain again in thin coats.
How long to wait before staining a new deck or pressure-treated fence?
Hold off until the wood has dried enough to absorb stain. With fresh pressure-treated lumber, that can take anywhere from several weeks to a few months. Treated wood is sold wet, and stain cannot soak into wood that is full of water.
Use a water test instead of counting days. When the water disappears into the boards within a few minutes, they are dry enough. A deck built here in late summer is often best left until the following spring.
Can I stain a deck while the wood is damp?
No. Damp wood will not take stain, and the stain will peel or go blotchy. After rain or a wash, give the deck two or three dry days.
Check the temperature and the dew too. Stain wants a mild, dry day and an evening without heavy dew, which humid summer nights near the water do not always give.
Should I stain or paint my wood fence?
For most wood fences, stain is the better finish. A fence has two faces, endless edges and posts in the ground, so water always finds a way in, and paint then peels. Stain wears down evenly and takes a new coat with no scraping.
HomeGuide lists painting or staining a fence at $2 to $14 per linear foot, or $4 to $9 per linear foot for a 6 foot fence, so 100 feet comes to $200 to $1,400. HomeGuide gives no lifespan for paint or stain on a fence. Paint is the right pick for a white picket fence when you accept the upkeep.
Is an old pine fence worth staining or should it be replaced?
An old fence is worth staining when the posts are solid and the boards are firm. If the posts rock at the ground or the boards are soft and split, the money is better spent on a new fence.
Push on each post. Frost heave and wet soil rot pine first at ground level, and a fence that leans will keep leaning under new stain.
Do you power wash before staining?
Yes. Decks and fences are washed before stain so dirt, mildew and loose grey fibers come off, at a pressure low enough not to tear the wood. Booked as stand-alone jobs, pressure washing runs $200 to $240 for a deck and $180 to $300 for a fence on HomeGuide's list.
