How much does it cost to stain a deck in Greenville, SC?

Deck staining in Greenville and Spartanburg starts at $4.00 a square foot for the floor with our Essential level, Exotic Timber Oil. Railings add $6.00 a foot and stairs $25.00 a step. A 200 sq ft deck with 30 ft of railing and 4 steps, washed first, usually runs $1,250 to $1,475.

Those numbers come from our deck staining cost calculator, the same one our estimators use, so they change when our prices do. If you are pricing deck staining in Greenville, here is how the number gets built, so you can tell a real quote from a guess.

What counts as square footage?

The square footage is the floor: length times width of the boards you walk on. Rails, balusters, stairs, posts, and skirting all take stain and all take time, so they are priced on their own. A 400 sq ft deck with a full rail system and two stair runs is a bigger job than 400 square feet of flat boards.

When two contractors price the same deck differently, ask each one what surfaces are in the scope. That question alone explains most of the gap.

Railings and stairs are hand work. Every baluster and every tread gets stained one at a time, which is why railings run $6.00 a foot and each step $25.00 at the Essential level. A 400 sq ft deck with 50 ft of railing and 8 steps, washed first, usually runs $2,450 to $2,875.

How does wood condition change the price?

Condition is the biggest lever. A new deck that reads dry on the moisture meter needs only a light cleaning, so the 200 sq ft example above drops to about $1,025 to $1,200.

Grey or mildewed boards need a soft wash and a brightener first, which adds $1.25 a square foot. That is the most common deck we see, and it is what the prices at the top include.

A peeling film from an old solid stain or a paint job is the hard end. It has to be stripped or sanded before new stain will bond, and that runs $2.85 a square foot instead of the wash. The same 200 sq ft deck with stripping runs about $1,550 to $2,000.

We check what is on the wood before we price it, and stripping is not always needed. Very grey or damaged decks are deck restoration first.

Restaining versus a first stain

A first stain on new pressure-treated pine is the cheapest deck job there is, as long as the wood is dry enough. Oil-based stain wants boards under 13% moisture, and new lumber can take a few months to get there.

Restaining a deck that was oiled a few years ago is usually a wash and a fresh coat. Restaining a deck that was left to grey, or that has a film finish on it, is where the prep line grows.

Adrian, Preston, and the team had by far exceeding my expectation. My wooden deck and stair need restoration and stain. It was definitely the right decision to hired this team. The quote was very fast, detail, and professional. Communication was the best I have ever experienced. Will definitely hire Superior Stain Solutions again for any future painting or staining project.

Why does a deck cost more than a fence?

Square foot for square foot, a deck is more work than a fence. The floor is flat, so it holds water and takes the sun square on. Prep has to be better and the stain has to be tougher.

People walk on it, so the finish has to stand up to wear. Rails and balusters are detail work. And an old peeling deck often needs stripping or sanding, not just a wash.

You are paying for more hours and more product per square foot. When you compare deck quotes, compare the prep steps line by line, not just the bottom number.

What about access, water, and power?

We need water and power for a proper wash. Tell us if the job site has no power or water. That can change how we quote it.

Steep yards, tight side gates, long carries from the truck, and decks built over landscaping all slow the work down. None of that is a gotcha. The calculator prices the deck itself; these are the things we look at when we come out.

Does the stain you pick still matter?

Yes. The Essential price is Exotic Timber Oil, a penetrating oil. On decks we lean hard toward penetrating oils because foot traffic and standing water punish anything that sits on top of the wood.

The upgrades, EXPERT Stain & Seal at $5.00 a square foot and EXPERT Log & Timber Oil at $6.50, come with manufacturer color warranties. If your deck already has a water-based stain on it, we stay with water-based, since oil will not soak through it. The calculator picks the right one from your answers.

Why check moisture first?

Every estimate includes a moisture-meter check. Oil-based stain wants wood below 13% moisture. Skip that in our humidity and you get peeling and blotch, and the deck looks worse than before you spent the money.

If your deck just got soaked by a week of afternoon storms, the honest answer might be to wait a few days. We would rather say that than take the job twice.
