DIY Deck Refinish Costs vs. Hiring a Pro

DIY deck refinishing costs less than hiring a pro, but it involves a lot of effort and you need a good understanding of carpentry and wood staining. Although hiring a local deck refinisher is more expensive, it ensures the work is done quickly and properly. You’ll also get a warranty on the work and parts.

“Refinishing a deck is a great way to refresh its look without the full price of a tear-off and reinstall,” says Andrew Kilborn, owner of Andy's Handyman Service in Des Moines, IA. “If you're up for it, it's a doable DIY.”


How do you refinish an old deck?

Some decks only require a minor wash with a specific deck wash applied with a hose. These methods don't require as much sanding. However, you can’t use them in all situations. Whichever method you use, you’ll need a long weekend with mild weather between 60 and 80 degrees, as well as cleaning supplies, a power washer, an orbital sander, and wood stain and supplies. Follow these steps:

  • Inspection: Examine your deck to be sure it’s still securely fastened to your house. Tighten loose screws and bolts, and replace any rusty fasteners. Check for damage and rot. If you notice structural damage or soft boards, it’s advisable to call in a deck specialist to repair your deck safely.

  • Cleaning: Cover any nearby plants or landscaping with plastic sheeting. Wearing appropriate hand and eye protection, use a wood cleaner to wash the dirt and debris off your deck.

  • Power washing: Power wash your deck at the appropriate pressure level for the type of wood.

  • Sanding: Allow your deck to dry completely or for at least 48 hours. For best results, use an orbital sander with the right grit of sandpaper for your deck. Use a lower grit for the floor of your deck and a higher grit for railings.

  • Staining: Use a sprayer for quick and even application, and blend in the stain with a roller, brush, or pad.

  • Cleanup: Dispose safely of deck refinishing supplies, as finish is often flammable. Put rags, pads, and brushes in a metal can and submerge them in water. Seal the can and dispose of it along with leftover stain, solvents, and other hazardous waste materials. Never throw these items away with the regular trash or wash them down the drain.

Can you put new decking over old decking?

No. There’s often decay beneath the decking where the fastener penetrates the joist. It’s better to cap, repair or replace joists. Although several products exist for this purpose, they increase the risk of moisture damage, rot, and can create spots for insects to live. Additionally, they're difficult to utilize on more complex decks with several levels, or stairs.

Why should you refinish a deck?

Refinishing a deck is important because it needs regular upkeep to maintain its appearance and functionality—especially if you live in a harsh climate.

Maintaining your deck allows you to keep enjoying your outdoor living space. Additionally, it increases the resale value of your home without you having to rebuild the deck.

How can I save money on deck refinishing?

You can save money on deck refinishing by following these guidelines:

  • Get at least three estimates from local contractors.

  • Make sure that each estimate includes materials, delivery, preparation, labor, and cleanup.

  • Hire a deck specialist instead of a general contractor.
