Deck Staining — Wash, Sand, Stain and Seal a Wood Deck
A gray deck, a stain that is peeling in the traffic lanes, or a new treated deck that has weathered long enough — cleaned, fixed and stained by the crew that also repairs decks.
JMB Builders does deck staining across the Twin Cities metro and north to St. Cloud. The deck is washed with a cleaner and brightener, dried, sanded where the grain is raised, loose boards and screws pulled tight, then stained and sealed in a transparent, semi-transparent or solid stain. Cracked or rotted boards are replaced before staining. Priced per project, quoted from photos of the deck.

A deck stain lasts as long as the prep under it. Stain over gray, dirty or mill-glazed wood sits on the surface and peels in the walking lanes the next spring. The job starts with a deck cleaner to lift the dirt and old finish, a brightener to open the grain and bring the color back, a rinse, and then time to dry. A moisture check tells us when it is ready, not the calendar.
Before the stain we do the carpentry. Screws that have backed out get driven, popped nails get pulled and replaced with screws, cupped boards get flipped or replaced, and rotted boards, usually at the stairs, the ledger or under a planter, get cut out and replaced with new treated lumber. Fuzzy or raised grain gets a light sand so the stain goes on even.
Then the stain: transparent or semi-transparent for a deck that still has good wood you want to see, solid for an older deck with patches and mismatched boards. Rails are done by brush, decking by pad and brush so the ends and gaps get coated. In Minnesota the window is the same as for exterior paint: warm, dry, and a couple of dry days after.
What you supply
- The stain color and type, or a photo of a deck you like; we can put two samples on a hidden board first
- Deck cleared: furniture, grill, planters and rugs off, or we move them and put them back
- Water at an outside spigot for the wash
- A word on any boards you already know are soft or loose

- Replacement of cracked or rotted boards and stair treads with new treated lumber, quoted from the photos
- Sanding of raised grain, rail tops and stair treads
- Stain and sealer applied by pad and brush, two coats where the product calls for it, ends and gaps coated
- Masking of siding, doors and concrete; plants covered and rinsed
- Photos of the finished deck in your job folder
How it is priced: per project
Quoted in writing from your photos within one business day. What moves the number:
- Deck square footage, plus rails and stairs, which take as long as the floor because they are all brush work
- Condition: bare gray wood that just needs cleaning vs. a peeling solid stain that has to be stripped
- Number of boards and stair treads that have to be replaced before staining
- Transparent or semi-transparent stain vs. a solid stain, which usually needs two coats
- Height off the ground; a walkout deck on a second story needs staging for the rails and skirting
- Skirting, lattice, benches, pergola posts and privacy screens added to the job
- A new deck that needs to weather first, which can mean two visits
Send a photo of the whole deck, one close-up of the worst boards and one of the rails. Say whether the old finish is a clear stain or a solid one. That is enough to quote the project.
How long it takes
A typical deck: one day to wash, repair and sand, a day or two to dry, and one day to stain. Rails and stairs add a half day. Stripping a peeling solid stain adds a day.

Situations and options
Clean and restain a gray deck
Wood that has not been stained in years and has gone gray. Cleaner and brightener bring the color back, loose boards are tightened, and a semi-transparent stain shows the grain again.
Strip and restain a peeling deck
A solid or film-forming stain that is flaking in the traffic lanes. Stripped with a deck stripper and scraped, brightened, sanded, then either a solid stain over the whole deck or a semi-transparent if the wood comes back clean.
First stain on a new treated deck
New pressure-treated lumber has to dry out before it will take stain; we test it with a moisture meter or a few drops of water. When it is ready, a penetrating stain seals it before the first winter. Decks we build get this as a line on the deck quote.
Solid stain on an old deck
Mixed boards, old patches and repairs all go one color under a solid stain. Rails, skirting and stairs included so the whole deck reads the same.
Repairs before staining
Rotted stair treads, cracked boards, a loose rail post or a soft board at the door. Replaced with new treated lumber, and the new wood is stained with the rest so it blends in over the first season.
Deck Staining — Wash, Sand, Stain and Seal a Wood Deck: questions, answered
Should a new pressure-treated deck be stained right away?
No. New treated lumber comes wet from the treatment and stain will not soak in until it dries out, which in Minnesota can take a season depending on the weather and the lumber. The test is simple: sprinkle water on a board; if it beads up, wait, and if it soaks in, it is ready. A moisture meter says the same thing with a number. Once it is ready, stain it before the first winter so it does not gray and check.
Do you power wash the deck before staining?
Yes, but the cleaner does the work, not the pressure. A deck cleaner lifts the dirt and dead gray wood, a brightener opens the grain and brings the color back, and the washer rinses it at a low setting. High pressure furs the wood and leaves wand marks that show through the stain. After the wash the deck dries for a day or two before any stain goes on.
What kind of stain is best for a deck in Minnesota?
A penetrating semi-transparent stain is the easiest to live with: it soaks in, shows the grain, wears instead of peeling, and can be cleaned and recoated without stripping. A solid stain hides old wood and mismatched boards but forms a film that has to be stripped when it fails. Transparent sealers look best on new cedar and need recoating most often. We pick with you based on the wood and how the last finish failed.
How often does a deck need to be restained?
Decking takes sun and foot traffic and usually needs a maintenance coat every couple of years; rails and vertical surfaces last longer. A deck that faces south with no shade wears fastest. The sign is water no longer beading on the boards. A penetrating stain can be cleaned and recoated when that happens, without stripping.
Can you fix loose or rotten deck boards before staining?
Yes, that is part of the job. Screws get driven, popped nails get pulled and replaced with screws, cupped boards get flipped or replaced, and rotted boards or stair treads get cut out and replaced with new treated lumber. We are a carpentry crew, so a loose rail post or a soft stair stringer found during the wash gets quoted and fixed on the same visit.
Will the new boards match the old ones after staining?
Under a solid stain they match right away. Under a semi-transparent stain the new boards take the color a little differently at first and blend in over a season as they weather; a new treated board may also need to dry before it takes stain at all. We tell you which to expect from the photos, and on a deck with a lot of replacements a solid stain is often the better choice.
