If you live somewhere like Cape Cod or South Shore, you want to take advantage of every opportunity to enjoy the outdoors. Building a deck for your home is a great way to spend time outside and not only increase your living space but also the value of your home.
Once you’ve decided to build a deck, your first question will probably be: “How much does it cost?” The answer can vary widely depending on factors such as size, materials, design complexity, and labor costs. Whether you’re planning a simple platform deck or a multi-level structure, understanding the cost breakdown is essential for setting a realistic budget.
Factors That Influence Deck Construction Cost
Several key factors influence the cost of deck construction. Each can have a significant impact on your final bill, so it’s essential to plan carefully and obtain detailed quotes before commencing construction.
Size of the Deck
A larger deck will require more time, labor, and materials, increasing the overall cost. The square footage is one of the primary factors that drives price.
Material Choice
The type of decking material, such as pressure-treated wood, cedar, composite, PVC, or hardwood, can significantly impact the cost. Composite and PVC materials are more expensive but require less maintenance.
Design Complexity
A basic rectangular deck will cost less than a custom, multi-level deck with intricate shapes, built-in seating, or curves.
Labor Costs
Labor rates vary depending on location and contractor experience. DIY projects save on labor but may increase time and complexity. Generally, if you don’t have experience with tools, construction, and the time to dedicate to a project, it’s best to hire a pro to ensure quality, safety, and value.
Permits and Inspections
Many areas require building permits for deck construction, which may include application fees and inspection costs.
Foundation Type
The type of footings or supports (e.g., concrete piers, helical piles) affects both labor and materials.
Height of the Deck
Elevated decks (especially second-story) are more expensive due to the need for railings, stairs, and stronger structural supports.
Add-ons and Features
Extras such as railings, stairs, pergolas, lighting, or built-in planters can significantly increase the total cost.
Site Conditions
Sloped or uneven terrain, poor soil conditions, or the need for clearing trees or rocks can add to construction difficulty and cost.
Season and Availability
Prices for labor and materials may fluctuate due to changes in demand, season, and supply chain issues. Contrary to what you might think, winter can be a great time to build a deck, even in Massachusetts.
Cost Estimates
Materials
The materials will be one of your most significant expenses, and the choice you make can depend on several factors. You should take into consideration your climate and durability needs. For areas with high humidity, rot-resistant materials such as composite or PVC may be preferable, despite their higher cost.
You should also think about maintenance costs. Ongoing maintenance costs, including staining and sealing, may offset lower upfront costs of natural woods (like pressure-treated or cedar). Having a budget of $75-$100 per square foot would be a healthy budget to allow your project to be built.
Some common decking materials, including labor, are:
- Pressure-Treated Wood – This is the most affordable and commonly used decking material. It’s treated to resist rot, decay, and insect damage, but requires regular maintenance, such as sealing or staining, to prolong its lifespan.
- Cedar or Redwood – These softwoods are naturally resistant to decay and insects, making them a more attractive option than pressure-treated wood. Cedar and redwood also offer a more premium look, but still require maintenance, such as sealing or staining, to preserve their color and integrity.
- Composite Decking (e.g., Trex, TimberTech) – Composites are made from a mixture of wood fibers and plastic, offering low-maintenance durability and a more consistent appearance than natural wood. They don’t require staining or sealing and are resistant to rot, fading, and scratching. However, they are more expensive than natural wood.
- PVC Decking (e.g., Azek, Veka) – Made from 100% plastic, PVC decks are highly durable, lightweight, and resistant to moisture, mold, and mildew. PVC decking is maintenance-free but often has a higher upfront cost than composite decking.
- Tropical Hardwoods (e.g., Ipe, Mahogany) – Tropical hardwoods are incredibly durable and beautiful, often chosen for their rich color and fine grain. These decks require minimal maintenance, but the high cost of materials and specialized labor can make them one of the most expensive options.
- Aluminum Decking – Aluminum decks are lightweight, extremely durable, and resistant to corrosion. They’re also low-maintenance, making them an excellent option for coastal or wet climates. However, the initial investment is high compared to wood or composites.
Labor
Labor costs for deck construction can vary depending on location, deck complexity, and the contractor’s experience. On average, you can expect labor costs to make up about 40-60% of the total project cost, with some general ranges as follows:
- Basic Deck — $15 – $30 per sq. ft.
- Complex Deck (multi-level, intricate designs) — $30 – $50+ per sq. ft.
- Hourly Rate — $50 – $100+ per hour (depending on experience and location).
Ongoing Expenses for Maintaining Your Deck
Maintaining a deck properly is key to extending its lifespan, keeping it safe, and preserving its aesthetic appeal. Depending on the material used for your deck, maintenance needs and costs will vary.
Annual cleaning is vital to remove dirt, mold, algae, and other debris. This prevents discoloration and damage. Professional cleaning usually costs between $300 and $500.
If you have a wooden deck, then sealing and staining are needed every one to three years, depending on weather conditions and exposure to sun, rain, salt, and other weathering agents. Professional sealing can range from $2000 to $4000, depending on the type of material and the size of the deck.
Decks are generally very durable, but regardless of the material they are made from, they can develop cracks or splinters over time. It’s essential to inspect your deck regularly to ensure you don’t overlook a minor issue that could become a significant problem in the future. The cost to repair and replace individual boards or pieces of hardware ranges from $400 to $1000 for the year.
