The average deck refinishing cost is about $3 to $6.80 per square foot. Your standard 200-square-foot deck will cost $600 to $1,360 or an average of $975.
You and your deck have been together through countless barbecues, weekend lounge sessions, and morning coffees. So, when you look beneath your slippers and realize it needs a little extra love, it’s up to you to oblige. Your deck refinishing cost varies based on labor, the size of the deck, and the finish you use. Any necessary repairs you find you need will add to the deck refinishing cost, too.

How Much Does It Cost to Refinish a Deck Yourself?
If you’re confident you won’t get stuck with a gloopy mess, a DIY deck refinishing can save you quite a bit of cash. Your budget will vary based on the size and state of your deck, plus what tools you have in your shed.
Here’s a basic list of what you’ll need:
|Tools and Supplies||Cost|
|Plastic sheeting (10’x25’)||$13|
|Deck scrub brush||$8|
|Three-pack sanding discs||$5|
|Paint sprayer||$250-$300 (or you can rent for $100 per day)|
|Power washer rental||$70 to $300 per day|
|Paint roller frame and rollers||$15|
|Stain and sealer||$40 per gallon*|
*Keep in mind that 1 gallon will cover between 200 and 300 square feet of deck.
Excluding the power washer and paint sprayer, as well as the stain and sealer, your basic tool cost comes to $146, give or take. Your power washer rental will bring that total to around $220 to $450.
Finally, there’s the paint sprayer to consider, which will add another $100 to $300 depending on whether you rent or buy. Then you just have to think about stain and sealer for $40 per gallon.
A DIY deck restoration also requires a major time commitment, as there are different steps you’ll need to follow to bring your deck back to its former glory:
Inspecting Your Deck
Before you begin budgeting the cost to refinish a deck, check out what you’re working with. Is your deck still securely attached to the house? Do you notice any rotting, soft boards, or other sketchy structural issues? You can’t slap on a fresh coat of finish to correct these problems.
Unless you’re quite handy with your carpentry skills, your best bet is having a local deck repair contractor handle this for you. An inspection can go for around $25 to $200 depending on how in-depth the review is. Side note: you should aim to have your deck inspected annually to ensure it’s safe and up to code.
Cleaning the Deck
Clean your deck with a good soapy scrub. A mildly soiled deck will do fine with a $10 deck cleaning solution and an $8 long-handled scrub brush. But for caked-on dirt and leftover paint chips, you’re better off renting a power washer for about $70 to $300 per day. Don’t go too crazy with the psi, though, as this can cause your wood to splinter.
Cost to Sand a Deck
Wait at least 48 hours for your deck to fully dry, then you can go to town with your orbital sander. You can pick up a sander for about $75, plus a three-pack of discs for $5.
Pro Tip: be sure you’re selecting the right grit for your wood. Floors usually call for a lower grit, whereas railings need a higher one.
Staining and Sealing
Many DIY deck stains come with built-in sealant and cost about $40 per gallon. A gallon usually covers 200 to 300 square feet, so you might need more than one.
For best results, apply with a paint sprayer, which costs around $300. If that price makes you flinch (we feel you), you can rent a paint sprayer for around $100 per day.
Also: we’re guessing you don’t want your landscape to match your deck stain, so you’ll want to pick up some plastic sheeting for about $13 to protect anything that shouldn’t be painted.
Deck Restoration Cost Breakdown
To preserve the beauty of your deck, be sure to keep up with cleaning, repairing, sealing, and other maintenance on a regular basis. A professional deck refinishing service near you can give your deck the TLC it deserves.
Cleaning the Deck
A professional power wash costs about $.40 per square foot, while the cost to rent a power washer is about $70 to $300 per day. This can also help eliminate any chipped paint and start you off with a smoother surface. Hiring a power washing pro will ensure you don’t go too hard and splinter your wood.
Repairing the Deck
If you find that the happy pattering of feet loosened your deck over time, or that greedy insects have been munching on it, you’ll have to budget for repairs in your deck refinishing cost. The average cost to repair a deck is about $1,820, but it can get up to $4,000 or even over $10,000 for larger and severely maimed decks.
Staining and Sealing the Deck
Staining a deck can cost $1 to $5 per square foot, while deck sealing will add about $.50 to $7 per square foot. It might cost more than a simple DIY job, but hiring a local deck staining pro will guarantee a smooth, beautiful application your neighbors will “ooh” and “aah” at.
What Factors Influence the Cost to Refinish a Deck?
Your deck restoration cost depends on labor, as well as the size and state of your deck. Repairs are another big factor that can quickly add dollars to your bill.
Deck Refinishing Costs for Labor
Your biggest deck resurfacing cost factor is labor. If we consider a 200 square foot deck, it could cost between $600 to $1,360 to have it done professionally. DIY-ing it might cost between $300 and $800, depending on what tools you already own.
Deck Restoration Cost
If your deck needs a lot of help, this will drive up your cost. Pest infestations can also happen, so you might need to hire an exterminator near you to evict any squatters. Structural repairs can get pricey, but they’re absolutely necessary before you can refinish the deck.
Deck Resurfacing Cost by Size
As you might have guessed, the bigger the deck, the higher the deck refinishing cost. Most pros charge by the square foot, and you’ll have to purchase additional gallons of stain and sealer if you’re taking on the project yourself.
