Introduction: Dream Deck, Reality Budget
Outdoor living is a fantastic way to enhance your home and lifestyle. A deck provides a space for relaxation, entertaining, and enjoying the outdoors. But often, the cost of building a deck can be a significant barrier. What if you could build a functional and attractive 8x10 deck for under $500? This guide provides a step-by-step approach to building a budget-friendly deck, focusing on cost-effective materials and DIY techniques.
We'll primarily focus on using pressure-treated lumber, a durable and affordable option that can withstand the elements. We'll explore how to design a simple yet sturdy structure, minimize material waste, and maximize your investment. Let's get started!
Planning and Preparation: The Key to Savings
Careful planning is crucial for any construction project, but it's especially important when working with a limited budget. Here's how to plan your 8x10 deck effectively:
1. Design and Dimensions
An 8x10 deck provides 80 square feet of outdoor living space, suitable for small gatherings or relaxing. This size is manageable for a DIY project and keeps material costs down. Consider the layout of your yard and how you intend to use the deck. Will it be a dining area, a lounge space, or a combination of both?
2. Obtain Necessary Permits
Before starting any construction, check with your local building department to determine if a permit is required. Many municipalities require permits for decks, especially those attached to a house or exceeding a certain height above ground [4]. Failing to obtain a permit can result in fines or even having to tear down your new deck.
According to the Decks.com, local rules might let you skip permits for detached decks under 200 square feet that sit less than 30 inches high, but these rules change by area [4]. The permit process needs construction plans, site plans with property lines and existing structures, and a permit fee between $50 and $600.
3. Create a Detailed Material List
A well-defined material list is essential for accurate budgeting and prevents unnecessary trips to the hardware store. Here's a sample material list for an 8x10 deck using pressure-treated lumber:
- Posts: 4x4 pressure-treated lumber (length depends on deck height)
- Beams: 2x8 pressure-treated lumber
- Joists: 2x6 pressure-treated lumber
- Decking: 5/4x6 pressure-treated lumber
- Fasteners: Deck screws, joist hangers, lag screws
- Concrete Mix: For post footings
Quantities will vary based on your specific design and local building codes. A sample material list from Craig Heffernan, includes:
- 6 - 80lb bags concrete mix for footings
- 5 - 4 x 4 x 10ft.
- 9 - 2 x 8 x 8ft
- 2 - 2 x 8 x 10ft
- 18 - 5/4 x 6 x 10ft decking
4. Shop Around for the Best Prices
Lumber prices can fluctuate, so compare prices at different lumberyards and home improvement stores. Consider buying in bulk to save money, and be on the lookout for sales and discounts. Pressure-treated lumber is generally the most affordable decking material [8, 12]. According to Decks.com, you can expect to pay between $3 and $6 per square foot for 5/4x6 ACQ-treated decking from a big box store [3].
Check online marketplaces or local classifieds for deals on lumber or other materials. You might find someone selling leftover materials from a previous project.
5. Tool Inventory
Assess which tools you already own and which you'll need to purchase or rent. Essential tools include a circular saw, drill, level, measuring tape, post hole digger, and safety glasses. Borrowing tools from friends or family can also save money.
According to Craig Heffernan, as a homeowner you should have these tools. You will be successful and proud at the end of your deck build [24]. If you decide this will be your first and last time building, then sell all the tools no less than 75% of what you paid for them.
Laying the Foundation: Posts and Footings
The foundation is the most critical part of any deck. Proper post and footing installation ensures the deck is stable and safe.
1. Determine Post Locations
For an 8x10 deck, you'll typically need at least six posts: one at each corner and two in the middle along the 10-foot sides. Proper spacing ensures adequate support for the deck [15].
2. Dig Footings
Dig post holes according to local building codes, typically extending below the frost line to prevent heaving. The depth of the frost line varies by location [4, 10]. Use a post hole digger or rent an auger for easier digging. According to Craig Heffernan, dig holes 10 to 12 inches round in diameter to 42 to 48 inches deep depending on the frost level in your area [24].
3. Pour Concrete Footings
Pour concrete into the holes to create solid footings. Use cardboard concrete forms to keep the concrete contained and level with the ground [10]. Insert anchor bolts into the wet concrete to attach post brackets later. Allow the concrete to cure completely before proceeding.
4. Install Post Brackets and Posts
Attach post brackets to the cured concrete footings using washers and nuts. Ensure the brackets are level and properly aligned. Place the 4x4 posts into the brackets and secure them with structural screws or nails. Make sure the posts are plumb before securing them [1].
Use pressure-treated posts on the brackets, checking that each post is level and secure. Use structural screws to attach the posts firmly to the brackets [10].
5. Cut Posts to the Correct Height
Use a level and measuring tape to mark the desired height on each post. Cut the posts to the marked height using a circular saw. Ensure all posts are the same height to create a level deck surface [1]. Treat all cut edges with a wood preservative.
Framing the Deck: Beams and Joists
With the posts in place, it's time to build the deck frame. The frame consists of beams and joists, which provide the structural support for the decking boards.
1. Install Beams
Beams are horizontal supports that run between the posts. Use 2x8 pressure-treated lumber for the beams. Attach the beams to the posts using screws and metal connectors [13]. Ensure the beams are level and securely fastened to the posts.
2. Attach Joists
Joists are parallel supports that span between the beams. Use 2x6 pressure-treated lumber for the joists. Space the joists 16 inches on center for adequate support [4]. Attach the joists to the beams using joist hangers and galvanized nails. Ensure the joists are level and properly aligned.
Standard deck joist spacing is 16 inches on-center, but diagonal decking needs 12-inch spacing for extra support [4].
3. Install Rim Joists
Rim joists are the outer joists that frame the perimeter of the deck. Attach the rim joists to the ends of the joists using screws and nails. Ensure the rim joists are flush with the joists and create a clean, finished edge [1].
4. Add Blocking
Blocking consists of short pieces of lumber installed between the joists to provide additional support and prevent twisting. Install blocking every 4-6 feet along the joist span. Secure the blocking to the joists with screws or nails [25].
Laying the Decking: Creating the Surface
With the frame complete, it's time to install the decking boards. This is where your deck starts to take shape and become a usable outdoor space.
1. Prepare the Decking Boards
Acclimate the decking boards to the outdoor environment for several days before installation to minimize expansion and contraction. Sort the boards and select the straightest ones for the most visible areas [5].
2. Install the First Board
Start by installing the first decking board along one edge of the deck frame. Use a chalk line to ensure the board is straight and parallel to the rim joist [11]. Secure the board to the joists with deck screws, spacing the screws evenly along the joist span.
3. Space the Remaining Boards
Use spacers to maintain consistent gaps between the decking boards. A 3/16-inch gap is generally recommended to allow for expansion and contraction [24]. Install each board, ensuring it's straight and properly aligned. Secure the boards to the joists with deck screws.
Timber deck boards require a 5 to 8mm expansion gap along the length of the deck boards and a 3mm gap along the ends of the deck boards [9].
4. Cut Around Posts
When you reach a post, measure and cut the decking boards to fit around it. Use a jigsaw to make precise cuts. Leave a small gap around the post to allow for expansion and contraction [5].
5. Trim the Overhanging Edges
Once all the decking boards are installed, use a circular saw to trim the overhanging edges. Use a chalk line to mark a straight line along the edge of the deck and cut along the line. This creates a clean, finished look [5].
Adding Finishing Touches: Stairs and Railings (Optional)
If your deck is more than 30 inches above the ground, railings are required for safety [25]. Stairs may also be necessary for access. These features can add to the cost of the project, so consider whether they are necessary for your needs and budget.
1. Building Stairs
If your deck requires stairs, calculate the rise and run of each step to ensure they are consistent and safe [4]. Use pre-cut stair stringers or build your own using 2x12 lumber. Attach the stringers to the deck frame and to a concrete footing at the base of the stairs. Install stair treads and risers using deck screws.
2. Installing Railings
Railings provide a safety barrier and enhance the appearance of your deck. Use 4x4 posts for the railing posts and attach them securely to the deck frame. Install railing balusters between the posts, ensuring they are spaced no more than 4 inches apart to prevent small children from falling through [4]. Attach a top rail to the posts to complete the railing system.
Cost-Cutting Tips and Considerations
Building a deck on a budget requires careful planning and resourcefulness. Here are some additional tips to help you save money:
- Use reclaimed materials: Consider using reclaimed lumber or other materials to reduce costs.
- Simplify the design: A simple rectangular deck is cheaper to build than a complex multi-level design.
- Do it yourself: DIY construction saves on labor costs, but be realistic about your skills and time commitment.
- Consider a floating deck: Floating decks, which are not attached to the house and sit close to the ground, often require less material and may not require a permit [7].
- Choose affordable decking alternatives: Consider cheap and easy decking alternatives. Compared with what has been discussed already, some cheaper alternatives to wooden decking boards include rubber mats, wood chippings and pallet decking [2].
