After a season of morning coffee, barbecues, and enjoying cool nights on your deck, it may look a little worse for wear. The good news is that refinishing a deck can restore it to tip-top shape without the time and expense involved in replacing it.
Refinishing a deck involves multiple steps, including inspection, cleaning, power washing, sanding, repairing, staining, and sealing. On average, the cost for these steps is around $980.
Average Cost to Refinish a Deck
The national average cost to refinish a deck is approximately $1,000, ranging from $3.00 to $6.80 per square foot. Hiring a Tasker for deck refinishing comes at an average rate of $51.62 per hour. When seeking external help, ensure that quotes itemize each service, including labor and materials.
However, several factors contribute to the overall cost of deck refinishing. Let’s break down each one:
Inspection
Before starting the process, your deck should undergo an inspection for mold, rot, and termites, which can cost between $25 and $100. Treating termites adds an additional $200. If the deck has structural damage, replacement is necessary.
Cleaning
Before refinishing your deck, it’s crucial to start with a thorough cleaning. If you choose to tackle the task yourself, expect to spend around $65 on cleaning supplies, which should include deck cleaner and protective gear such as gloves and safety glasses. Keep in mind that this estimate does not account for the cost of a power washer. Power washers can range from $100 to $1,500 if you decide to purchase one. Alternatively, if you opt to rent a power washer, daily rates typically range from $50 to $65.
Cost to Sand a Deck
Sanding a deck typically requires seven hours of work, with an average cost of $280. The price range falls between $210 and $350, translating to $1 to $3 per square foot. While it’s possible to take on this project yourself, you’ll need to invest in an orbital sander, which generally costs around $75. Alternatively, you can opt to rent a floor sander, with daily rental prices ranging from $40 to $70. Keep in mind that if you choose the floor sander option, you’ll also need to purchase sander discs, usually priced at $5 for a three-pack. When sanding, utilize low-grit sandpaper for the boards and high-grit sandpaper for the railings.
Deck Painting Cost
For optimal results when applying deck sealant, consider investing in or renting a paint sprayer. The cost of purchasing a new one is $300, but if you prefer the rental option, you can obtain a paint sprayer for $100 per day.
Deck Resurfacing Cost
Deck resurfacing encompasses both the expenses associated with sanding and those tied to repainting or staining the wood. On average, the total cost amounts to approximately $900, equivalent to $4.50 per square foot. It’s worth noting that the choice of stain also plays a role in determining this cost; further details on the pricing and types of deck sealants are provided below.
Deck Restoration Cost
Restoring your deck involves repairing and rejuvenating it. First, your deck will be inspected for issues such as mold, rot, warped areas, and pests. Restoring encompasses sanding and staining the deck. On average, the total price is approximately $1,080, falling within a range of $980 to $1,189. The specific materials required for the job, as well as your deck’s overall condition, contribute to the variability in costs.
Factors That Impact a Deck Refinishing
In addition to the cost involved in deck refinishing, other factors should be taken into account.
See the breakdown below.
Labor Costs
A substantial portion of the total cost is attributed to labor. Anticipate that 50 to 65 percent of your budget will be allocated to labor expenses, ranging between $450 and $800 for a standard deck. As a best practice, obtain quotes from three different professionals.
Size: Square Foot
The dimensions of your deck directly influence the cost of refinishing, along with factors such as the number of steps and railing. If after inspection step replacement is necessary, add approximately $20 per square foot of steps to your total cost.
Type of Finish
The final and crucial step in deck refinishing is staining and sealing. Many stains also serve as sealants, with prices ranging from $20 to $120 per gallon. Generally, one gallon covers an area of 200 to 300 square feet. We recommend selecting a stain priced at $40 or more to ensure optimal quality.
There are two main types of stains: water-based and oil-based. Water-based stains, while more expensive, are not as durable as their oil-based counterparts. However, they are easier to clean and environmentally friendly. On the other hand, oil-based stains are known for their durability, ability to penetrate the wood, and easier maintenance.
Location
The cost of living in your area significantly influences all these factors. If you reside in or near a major metropolitan area, anticipate higher service costs.
DIY Deck Refinishing
Refinishing your deck is a labor-intensive task that typically requires a minimum of three days of effort and several tools that you may not already own. Despite these considerations, it remains a manageable project. However, it’s important to note that while you may save on labor costs (ranging from $425 to $800), there could be a corresponding increase in expenses for supplies (estimated between $350 and $750, factoring in finishes that can cost up to $120 per gallon).
Keep in mind the significance of checking the structural integrity of your deck and inspecting for pests. If you lack experience with inspections, sanders, and power washers (which can potentially damage wood), it’s advisable to consider outsourcing the job. Going with someone with experience, like a Tasker, is your best bet to avoid paying someone to fix your mistakes.
Deck Refinishing Cost FAQs
Can an old deck be restored?
Yes, an old deck can be restored, provided that the joists, foundation, and overall structural integrity of the deck are sound. Any rotting wood planks will need to be replaced before refinishing takes place.
How often to refinish a deck?
It is recommended to refinish your deck every one to three years. In the interim, regular maintenance tasks such as re-sealing, cleaning, and removing snow should be performed to ensure the deck’s longevity and appearance.
What are the benefits of deck refinishing?
Refinishing your deck offers advantages such as enhancing curb appeal and extending the deck’s lifespan.
Can you put new decking over an old deck?
Placing new decking over old decking is not advisable, primarily due to the potential decay in the old wood. This decay can impact the joists, and in such cases, it is preferable to repair or replace the joists. Failing to do so may lead to increased risks of moisture damage, rot, and create potential habitats for pests.
Decks go through a lot, but that doesn’t mean they have to remain an eyesore (even if the thought of refinishing your deck seems daunting). Book a Tasker to save yourself time and peace of mind of a job well done with all your deck restoration needs.
