How Much Does It Cost to Build a Mahogany Deck in 2025?

This article was updated using automation technology and thoroughly reviewed for accuracy by HomeAdvisor Editor Ryan Noonan.

Mahogany decks cost an average of $14,250, with most prices ranging from $5,900 up to $18,400. In some cases, the final price can range from as low as $1,500 to as high as $21,000, depending on the deck size, design, and labor requirements. Because mahogany remains more affordable than many other wood decking materials, it’s a popular choice for homeowners who want to enhance the appeal of their property without stretching their budget.

Cost to Build a Mahogany Deck per Square Foot

The total cost to build a mahogany deck ranges from $25 to $70 per square foot, including both materials and labor. However, the final price may vary depending on labor costs and the size of the deck you’d like.

Cost to Build a Mahogany Deck by Style

Your deck doesn’t need to be a replica of every other deck in the neighborhood. You should consider where you want it built and what shape it should be to help determine the cost of deck installation.

Custom Shape

Mahogany decks that require a custom shape, such as an L-shape or wrap around, should expect to add 50% to 100% more to their budget. These custom shapes can be complicated, especially if you’re working with slopes in the yard.

Floating Mahogany Deck

A floating mahogany deck is situated away from the house, rather than being attached like a traditional deck. Floating decks cost 10% more on average, as they require more foundational support. Though it’s not unusual to see an increase of 25% if the area where you want the deck requires extra foundational support.

Ground-Level Mahogany Deck

If you prefer a ground-level mahogany deck, you’ll spend 10% to 15% less because the design needs less structural support and no stairs. However, if the ground where the deck will be doesn’t have the best support, this might reduce the savings.

When designing a ground-level deck, be sure to plan for ground cover (such as landscape fabric and rock or stone) underneath the deck to minimize plant or weed growth.

Second-Story Mahogany Deck

Going in the opposite direction of the ground, you have the option for a second-story mahogany deck. These decks require extra structural support to maintain structural integrity on both floors and the extra stairs. Expect a price increase of 15% to 20% for this style of mahogany deck.

Mahogany Deck Cost Factors

The cost to build a mahogany deck depends on several key factors, including labor, material prices, and required permits. 

Materials

Along with mahogany deck boards, which cost $25 to $11 per square foot, there are several other materials you’ll require to build a deck. You’ll need to factor in joists, fasteners, and other hardware when estimating total material costs.

Labor

Expect to pay close to 50% of the overall project price for labor alone. Hiring a deck company near you will cost $15 to $35 per square foot.

Permits

When it comes to permits and their associated prices, you’ll need to contact your local municipality for more information. You should expect to pay anywhere from $100 to $500 in building permit fees.

Additional or Unexpected Costs

Don’t be caught off guard by delivery fees for mahogany decking. Mahogany wood originates from Central and South America, which can result in higher import costs. Add a 5% to 10% contingency to cover potential delivery fee increases.

Old Deck Removal

Pricing for old deck removal will vary depending on the state of the old deck, as well as its size. The removal of an old deck can range from $500 to $3,000, which includes tearing down the deck and disposing of the debris.

DIY Mahogany Deck Install vs. Hiring a Pro

If you’ve worked on decks before or have dabbled in other major projects such as hardwood floor laying or building a shed, you might be able to tackle this job yourself. Even with that experience under your belt, building a DIY deck is still no easy feat. These are the major tools and materials you’re going to need to handle this project:

Professional deck builders bring specialized tools, code knowledge, and proven workflows that streamline installation and reduce rework, resulting in labor cost savings. If schedule, code compliance, or resale value are a concern, hiring a professional deck builder is the smarter choice.

Request quotes from licensed deck builders near you to compare pricing, timelines, and warranties.

Ways to Save When Installing a Mahogany Deck

Mahogany decking offers luxury at a premium price, but savvy homeowners can still find ways to reduce costs without sacrificing quality:

• Consider smaller dimensions or a simpler design to reduce both material and labor costs while maintaining the elegant look of mahogany.

• Get multiple quotes from contractors, as pricing can vary significantly between deck builders for the same specifications.

• Purchase materials directly from suppliers rather than through contractors to eliminate markup fees.

• Schedule your project during the off-season (fall or winter) when deck builders may offer discounted rates to maintain their workflow.

• Choose a ground-level design to minimize structural requirements and eliminate the need for expensive railings and stairs.
