Overview

Exterior decks and porches are highly desirable features that can significantly enhance a property's value and appeal. As a house flipper, you need to inspect the condition of existing decks and determine whether they can be repaired, re-decked, or replaced entirely. This guide provides the knowledge to estimate deck project costs accurately.

Things to Look For

When inspecting a deck, check for signs of rot, decay, or insect damage. Look for loose boards, unstable railings, and any structural issues. Consider the overall aesthetic of the deck and how it contributes to the outdoor living space.

Price Ranges

Deck costs vary considerably depending on whether you're building a new deck or simply replacing the decking boards. New decks, including structure, decking, and railings, can range from $15 to $50 per square foot, depending on the materials used. Replacing existing deck boards is generally more affordable, ranging from **$5 to $15 per square foot**.

Labor & Installation Costs

Installation Timeline

A decking crew can typically complete a 10x10 foot (100 square foot) deck in 3 to 5 days. The first day usually involves layout, digging footings, and pouring concrete. The following days are for framing, installing decking, and building railings.

Material Costs

  • Lumber: Pressure-treated lumber is commonly used for framing, while various wood species (cedar, redwood) or composite materials are used for decking.
  • Fasteners: Screws, nails, and other hardware are needed for assembly.
  • Railing Materials: Railings can be made of wood, metal, or composite materials.
  • Concrete:  Concrete is used for footings.
  • Stain and Sealant:  These protect the wood and enhance its appearance.
  • Location Factor

    Location Adjustment

    The prices in the table are based on a typical deck in an average suburban area. Deck costs can vary substantially by location. If you are located in the East or West Coast, you could expect to pay 15% to 50% more than the recommended price provided. Consult our location multiplier index for more accurate pricing in your market.

    Determining Your Local Prices

    While our deck cost guide provides a helpful starting point, it's important to remember that actual prices can differ significantly based on your location. Factors such as regional material costs, labor rates, and local demand all play a role in determining the final project cost.

    To get the most accurate estimate for your area, we strongly recommend contacting local deck builders directly. When you reach out, be as clear and specific as possible about your needs. Explain that you're a real estate investor seeking a rough budget for a deck project. Provide details such as:

    • Type of deck: Are you looking to build a new deck or replace an existing one?
    • Materials: What decking materials are you considering (e.g., pressure-treated lumber, cedar, composite)?
    • Approximate size: What is the approximate size of the deck you have in mind (e.g., 10x12 feet, 12x16 feet)?
    • Features: Will the deck be ground-level or elevated? Will it have stairs, railings, or other features?

    The more information you provide, the better equipped the contractor will be to give you an accurate estimate. While they may hesitate to give a firm quote without a site visit, most should be willing to provide a general price range for your project. This will help you refine your budget and make informed investment decisions.

    Tips for contacting contractors:

    • Be upfront about your needs: Let them know you are in the early stages of planning and gathering preliminary estimates.
    • Don't pressure them for a firm quote: Explain that you will contact them for a formal quote when you have a specific property and project ready.
    • Get multiple quotes: Reach out to several deck builders in your area to compare pricing and find the best fit for your needs and budget.

    Other Factors

  • Type of Deck Material: The choice of decking material significantly impacts the cost. Pressure-treated lumber is generally the most budget-friendly, while cedar, composite, and exotic hardwoods increase the price.
  • Deck Size: Larger decks often benefit from economies of scale, meaning the cost per square foot may be lower compared to smaller decks.
  • Deck Height:  Elevated decks require more materials and labor for structural support, such as posts, beams, and footings, which can increase the overall cost.
  • Deck Shape and Complexity:  Simple, rectangular decks are typically less expensive to build than those with complex shapes, multiple levels, or intricate designs. These complexities require more labor and materials.
  • Deck Features: Adding features like stairs, built-in seating, pergolas, or custom railings will increase the overall cost of the project.
  • Deck Removal: If an existing deck needs to be demolished and removed before building a new one, this will add to the labor and disposal costs.
  • Staining and Sealing: Applying stain and sealant to protect and enhance the appearance of the deck adds to the material and labor costs.
  • Permit Costs:  Depending on your location and the size of the deck, you may need to obtain building permits, which can add to the overall project expenses.
  • Location:  Labor and material costs can vary significantly depending on your geographical location. Urban areas and regions with high construction demand often have higher deck building costs.
  • Seasonality: Deck builders are often busiest during peak seasons, like spring and summer. Scheduling your project during these periods may result in higher prices due to increased demand and limited contractor availability.
  • How to Estimate Deck and Porch Costs

    Measurements

    Estimating deck costs involves calculating the total square footage of the deck and multiplying it by the cost per square foot for your chosen materials and labor.

    1. Measure the length and width: Measure the length and width of the deck surface.
    2. Calculate the area: Multiply the length and width to find the total square footage.
    3. For complex shapes: If the deck isn't a simple rectangle, break it down into smaller sections, calculate the area of each section, and add them together.

    Calculating Your Budget

    Now that you've measured your deck and have a good understanding of the total square footage, you can calculate a rough budget for your deck project. To do this, multiply the total square footage by your budgeted price per square foot for the type of deck you want to build or replace.

    For example, let's say you have a 100 square foot deck that you want to replace with new pressure-treated lumber. If your budgeted cost for this type of deck is $7.50 per square foot, your estimated budget would be:

    • 100 square feet x $7.50/square foot = $750

    Keep in mind that this is a rough estimate. The actual cost may vary depending on factors such as the complexity of the deck design, the height of the deck, and whether you need to remove an existing deck.

    Always consult with local deck builders for accurate pricing in your area.

    Example

    For a 10x12 foot deck (120 square feet) using pressure-treated lumber:

    • Deck area: 120 square feet
    • Estimated cost for a new deck (using $20/sq ft): 120 square feet x $20/square foot = $2,400
    • Estimated cost to replace decking boards (using $7.50/sq ft): 120 square feet x $7.50/square foot = $900

    This shows the cost difference between building a new deck and simply replacing the decking boards.
