However, keep in mind that the final price to replace deck boards depends on several factors such as deck size, deck material, extent of damage, contractor costs, any customizations, and the necessary prep work.
We’ll discuss all these factors in detail below along with tips on how you can save money.
Deck Replacement Cost Breakdown
While deck size and material are the primary factors affecting the cost of deck replacement, we’ll also explore other factors that impact the cost in detail, one by one.
Deck Size
The size of your deck plays a major role in replacement costs, as larger decks require more materials and labor.
Most decks are between 150 and 400 square feet, with construction costs typically ranging from $30 to $60 per square foot.
On average, this comes to about $45 per square foot, which includes materials, labor, local permits, and foundation costs.
- The Size of a DeckAverage Cost
- 10-by-10$4,500
- 12-by-12$6,500
- 12-by-14$7,600
- 14-by-14$8,800
- 16-by-16$11,500
- 20-by-20$18,000
Deck Material
There are plenty of materials available for decks, such as wood, composite, metal, and PVC. The cost of deck replacement varies significantly depending on the material used. Here’s a breakdown of the costs according to material type:
- Deck MaterialAverage Cost per Sq Ft (labor + material)
- Composite$30 - $50
- Wood$25 - $65
- Vinyl$30 - $55
- Metal$30 - $55
Composite
Composite decking is crafted from a blend of wood fibers and recycled plastic, offering the look of wood without the hassle of high maintenance.
Composite deck costs usually range from $30 to $50 per square foot with the labor cost to replace deck boards with composite materials included in this estimate. If you’re only considering materials, the cost is typically between $12 and $30 per square foot.
While composite decks are durable and resistant to rot, insects, and fading, they can become hot when exposed to direct sunlight.
Wood
Wood decking is a popular option for outdoor spaces because of its natural beauty and versatility.
Pine is a cost-effective and commonly used wood. However, it requires chemical treatment to resist rot and insects, along with regular maintenance to prevent warping and extend its lifespan.
Cedar and redwood are naturally resistant to decay and insects, offering a longer lifespan of 15 to 30 years with proper care.
Exotic hardwoods like Ipe are incredibly durable, with a lifespan of up to 50 years, but they come at a higher cost.
The kind of wood you select will influence the overall cost. Typically, installation costs range from $20 to $50 per square foot, while materials alone usually run between $5 and $15 per square foot.
Vinyl
PVC (Polyvinyl Chloride) decking is made entirely from synthetic materials, making it highly durable.
This type of decking is extremely low maintenance, resistant to moisture, mold, and insects, and doesn’t fade or stain. It’s also lightweight but may have a less natural look and can become slippery when wet.
Installing vinyl decking typically costs between $24 and $40 per square foot. For materials alone, the cost ranges from $7 to $15 per square foot.
Metal
Metal decking, particularly aluminum and steel, is valued for its exceptional durability and low maintenance needs.
Aluminum decking is lightweight, rust-resistant, and stays cool underfoot, making it an excellent choice for hot climates.
Steel decking offers superior strength and load-bearing capacity, making it ideal for high-traffic areas or structures that need extra support. However, it is heavier and can rust if not properly treated.
Both aluminum and steel provide long-lasting, fire-resistant decking options, though they don’t offer the natural look of wood.
Metal decking materials typically cost between $10 and $20 per square foot, with professional installation ranging from $20 to $35 per square foot.
Contractor
Labor costs, ranging from $8 to $22 per square foot depending on the project’s complexity and location, make up a significant portion of the total expense.
For example, simpler designs tend to be cheaper since they require less time and expertise, whereas more complex designs with features like multiple levels or custom-built elements drive up labor costs.
Additionally, geographic location matters too – urban areas typically have higher labor costs than rural areas.
If you’re only looking to have your deck repaired, labor costs will likely fall between $100 and $500.
Additional Cost Factors to Consider for Deck Replacement or Repair
When redoing a deck, there are several other factors that can impact the overall cost of your project and should be taken into account.
Railing Replacement
- Deck Railing MaterialCost per Linear Foot
- Wood$50 - $70
- Metal$60 - $90
- Composite$90 - $170
- Glass$150 - $220
The cost to replace deck railings varies significantly depending on the materials used, typically ranging from $40 to $250 per linear foot.
For instance, wood and metal railings tend to be more budget-friendly, while glass railings are on the pricier side.
Labor costs to install deck railings can add about $20 per linear foot.
Additionally, the style and complexity of the railings, such as those for stairs or gates, can increase the overall cost. Special features like premium colors, caps, and accessories can also contribute to higher expenses.
Season
During the winter, the lower demand for deck construction often results in reduced labor costs and potentially quicker permit approvals.
Contractors may offer discounts or have more availability during this off-season, making it a more budget-friendly time for deck replacement.
On the other hand, spring and summer are peak seasons, where higher demand can lead to increased labor costs and longer wait times for project completion. Material costs might also rise with seasonal demand.
Prep Work and Demolition
The cost of demolition usually ranges from $2 to $6 per square foot, depending on factors like the deck’s size, materials, and complexity.
Accessibility also affects the price. If the site is hard to reach, it may require extra labor and specialized equipment, which can drive up your costs.
To keep expenses in check, it’s wise to plan carefully and get multiple quotes.
Permits
Permit fees can go up to $600, depending on where you live and the project’s scope.
The permit process is essential to ensure the deck meets local building codes and safety standards with inspections required at different stages.
Skipping permits can lead to legal troubles, fines, or even the need to dismantle the deck, which could end up costing you more.
Customizations
Customizations can greatly increase the cost of replacing a deck due to the added complexity, extra materials, and more labor involved.
Features like built-in benches, lighting, or custom railings can drive up expenses significantly. For instance, curved designs or multi-level decks require more detailed construction and thus, higher labor costs.
How to Determine If Your Deck Needs to be Repaired or Replaced?
A thorough inspection by a professional is the best way to decide whether you’re replacing the deck or just repairing it, but here are some key signs that can help you determine that too.
Should You DIY Deck Repair or Replacement or Hire a Professional?
DIY repairs can be a great way to save money, especially for minor tasks like surface maintenance or replacing a few boards if you have the necessary skills and experience.
However, if your deck has structural issues like wobbly railings or sagging sections, it’s wise to hire a professional. They’ll ensure your deck is safe and up to code.
For a full deck replacement, you’ll need significant carpentry knowledge and must follow building codes closely. Mistakes can result in safety hazards and more expensive repairs later on.
While hiring a professional may cost more upfront, they provide expert craftsmanship, ensure compliance with regulations, and often complete the job more quickly, potentially saving you money on future repairs.
If your project is complex or involves structural repairs, or if you’re not experienced in carpentry, hiring a professional is the safer, more reliable choice.
When selecting a professional, check their online reviews and get quotes from multiple companies. You can also use a tool like HomeBuddy to find local experts who can design and install a deck that suits your style and budget or replace your old one with minimal hassle.
