Other Factors Affecting Deck Costs
How much does it cost to build a deck? Though you’ve learned the price by size and averages, here are the factors that might affect how much you spend:
Deck Material
Material costs for a deck range from $2 to $19 per square foot, which doesn’t include additional parts or labor costs. A pine deck might be beneficial if you have a smaller budget. However, composite decking or Ipe will resist the elements much better and could be the top choice for deck materials.
Cost Per Square Foot for Different Decking Materials
Here’s a breakdown of the cost per square foot for decking material only:
- Composite – $8.20 to $13.30
- Cedar – $3.40 to $6
- Pine (pressure-treated) – $2 to $3.75
- Ipe (exotic) – $9 to $16
- Redwood – $5.50 to $19
- PVC – $10
What to Consider When Choosing Decking Material

When focused on choosing your deck material, consider these things:
- Budget – Pressure-treated pine is ideal for homeowners on a tight budget. Still, Ipe decks will last 50+ years, and pine is only suitable for 10 to 15 years.
- Location – Composite decking material will hold up well in sunlight, but Ipe doesn’t get as warm as other wood decks.
- Outdoor Decor – Natural wood decking is the answer if you prefer a rustic look. Composite materials are customizable and can fit within your outdoor living space.
- Maintenance – PVC requires less maintenance than a wood deck

Composite Decking vs. Ipe
Ipe is also called Lapacho or Brazilian Walnut, an exotic hardwood found in South America. The cost per square foot is $9 to $16, and it’s highly durable and very beautiful.
On the other hand, composite decking is more eco-friendly and made of plastic and recycled wood. Composite decks usually cost $8.20 to $13.30 per square foot and are highly durable compared to wooden decks.
Let’s see how these two options compare:
- Durability – Ipe wood is often more durable than composite decks. It’s naturally resistant to weather, fungus, and insects and is denser than standard wood. Plus, it features a class A rating for being resistant to fire. Therefore, it lasts longer and might require fewer repairs as the years go by.
- Appearance – Homeowners like the natural beauty of Ipe, but there’s little flexibility. Composite decking comes in many colors and is customizable to your preferences.
Softwoods (Pine, Cedar, Redwood Deck)
If you’re on a budget, these options might work better:
- Pressure-treated Wood – Pine isn’t naturally resistant to the elements, so stain or seal it. However, it’s easy to install and low-cost.
- Redwood – This is beautiful and resistant to the elements. Plus, it won’t need any chemical treatments.
- Cedar – This is an attractive option from Canada and the Western US. The cost per square foot is $3.40 to $6.
Compared to natural wood decking, it’s pretty durable and looks great. Likewise, the price is right for many homeowners.
Deck Design/Style

Choosing a simple deck design can save money. However, if you can spend more, you may consider these styles:
- Wrap-around Decks – These are often attached to the home and cost $5,200 to $17,600. They might be called platform decks.
- Intricate Designs – Decks can have intricate designs, such as curves. This can cost $4,610 to $18,085.
- Built-in Seating – These cost $4,245 to $16,040. It’s often better to get prefabricated seats.
- Raised Deck – A raised deck is great in flood zones and uneven terrain. You’ll pay $3,970 to $10,940 here.
- Floating Decks – These are called freestanding decks and aren’t attached to the home. They often cost $6,000 to $24,000 and require more maintenance than others.
- Multi-Level Deck – Building second-story decks can separate everything into parts. However, it can cost between $35 and $75 per square foot.

Before the contractor can build the deck, you’ll need to prepare the site for construction. This can include:
- Land-clearing costs

Building a Deck – Location

Property Taxes
Adding a deck will boost your home’s resale value, which could raise your property taxes. It’s wise to call the local tax collector to learn more.
Building Permit
Deck building will likely require a permit, and the prices and requirements will vary. Therefore, it’s wise to find this out before you get started.
Climate
The climate affects which materials to use. Composite decks work well in ice and snow, while Ipe decks fare better in the heat.
Labor
You can expect to pay higher labor costs if you live in the city or have a higher-than-normal cost of living.
Materials
If the materials are locally available, you might spend less. However, you must also remove the old deck and pay to dispose of those materials.
Homeowners’ Insurance
The new deck could increase your homeowners’ insurance premiums. Therefore, you should talk to the insurance agent before beginning a project.
