Average Cost to Build a Floating Deck

Floating Deck Prices

Here are the materials you will need to build a floating deck:

• Post hole digger: $50–$300

• Shovel: $25–$50

• Hammer: $10–$20

• Decking nails: $15–$30

• Screwdriver: $10–$15

• Deck screws: $10–$20

• Lumber: $2–$30 per square foot

• Exterior wood coating: $10–$55 per gallon (each gallon covers 150 to 300 square feet)

So, if you were to build a standard 12-foot-by-12-foot deck (144 square feet), you can expect to pay between $420 and $4,800 just for materials for this project.

Floating Deck Installation Cost

Generally, about 50% of floating deck installation costs go to labor, with the other half going to materials. As a result, you could cut the cost of your project in half by doing it yourself. However, keep in mind that this assumes you could get the same deals on materials that the pros get, and that may be tough to do if you don't have the connections.

Floating Deck Labor Costs

You can expect a deck contractor to charge about $15 to $35 per square foot for this job. So if you were to hire someone to build a floating deck that is 15 feet by 15 feet, or 225 square feet, it would cost you between $3,375 to $7,875 just for the labor.

Floating Deck Cost by Type of Wood

The cost to build a floating deck will vary dramatically based on the most important element of that deck: the wood. For example, the cost of a cedar deck will differ dramatically from the cost of a composite deck. Here is a breakdown of the different types of woods and what you can expect to pay on a square-foot basis:

• Pressure-Treated Wood: $2–$5

• Redwood: $5–$30

• Mahogany: $8–$11

• Ipe: $10–$20

• Tigerwood: $7–$15

• Bamboo: $3–$10

• Cedar: $3–$7

• Aluminum: $15–$20

• Fiberglass & Composite: $12–$22

DIY vs. Hire a Floating Deck Installation Pro

So, should you take on the project yourself or hire a professional to handle the job? Deck installation is a lot of work, but a relative novice could pull this off with the right materials and equipment. A floating deck doesn't come with the complications of attaching it to a house, so that might make it even more appealing to DIYers.

However, there are several good reasons to go with a professional. For one thing, it’s a difficult job and one that can quickly go wrong, resulting in a structure that may need rebuilding if it's not up to par. For another, professionals have the connections to get the best possible prices for lumber and other materials. And finally, wouldn't it be nice to kick up your feet with a glass of lemonade while someone else does the work—all while knowing the deck you're getting will be top quality?

Before you get started with installing a floating deck on your own, at least get a professional opinion and contact a deck company near you. They will come out to your property, survey the area, make recommendations, and provide you with a quote. Then, you can decide whether you'd rather do it on your own.

FAQs

Do I need a permit for a floating deck?

You don't need a building permit to build a floating deck, which is one of the great things about it. Because it’s not part of your home’s general structure, you have more freedom to build the deck you want without getting permits first. However, check with your local government to see if any restrictions may affect you.

Can I build a deck directly on the ground?

You can build a deck directly on the ground as long as you have the right materials that won't rot due to contact with the ground. This is one area where it may be best to consult with a professional first. They can tell you what materials to use and give you other tips on doing the job right.

What are the disadvantages of a floating deck?

Floating decks tend to require a lot of maintenance, which is a major disadvantage to consider before building one. They’re close to the ground, so you have issues with moisture and vegetation growing between the wood. This means you should anticipate quite a bit of maintenance.
