Dreaming of a cozy outdoor space where you can relax, entertain, or simply enjoy the fresh air? Building a small deck yourself is an achievable and rewarding project that can significantly enhance your backyard. This DIY guide will walk you through the process, from planning to construction, providing practical advice and tips to ensure a successful outcome. Whether you're a seasoned DIY enthusiast or a beginner, this guide will empower you to create a beautiful and functional deck that you can enjoy for years to come.
Planning Your Small Deck
Before you even think about picking up a hammer, careful planning is essential. This stage involves determining the size and location of your deck, obtaining necessary permits, and designing the structure.
1. Size and Location
Consider how you intend to use your deck. Will it be primarily for dining, lounging, or grilling? This will influence the size you need. A small deck typically ranges from 8x8 feet to 12x12 feet, but adjust as needed for your specific needs and available space. When choosing a location, consider:
- Sunlight: How much sun does the area receive? Do you want a sunny deck or a shaded retreat?
- Accessibility: Is it easily accessible from your house? A deck directly off a back door is ideal.
- Privacy: Consider the proximity of neighbors and whether you'll need to add screens or plants for privacy.
- Ground Conditions: Ensure the ground is relatively level and stable. Avoid areas with poor drainage or large tree roots.
2. Permits and Regulations
Building codes and permit requirements vary by location, so it's crucial to check with your local building department before starting any construction. Most municipalities require permits for decks above a certain height (usually 30 inches) or size. Obtaining the necessary permits ensures that your deck meets safety standards and avoids potential fines or legal issues down the road. You may need to submit a site plan and construction drawings as part of the permit application.
3. Deck Design
Sketch out your deck design, including dimensions, post locations, and framing details. There are many online resources and software programs that can assist you with deck design. Consider these factors:
- Shape: A simple square or rectangle is easiest to build, but you can also incorporate curves or angles for a more custom look.
- Height: Determine the height of your deck based on the height of your house's threshold. Ideally, the deck surface should be slightly lower than the interior floor level to prevent water from entering your home.
- Framing: Plan the layout of your deck joists and beams to ensure adequate support for the decking. Common joist spacing is 16 inches on center, but this may vary depending on the type of decking you choose.
- Stairs: If your deck is elevated, you'll need to include stairs in your design. Follow local building codes for stair rise and run requirements.
Choosing Your Materials
The materials you select will significantly impact the appearance, durability, and cost of your deck. Common choices include wood, composite, and PVC decking.
1. Wood Decking
Wood decking offers a natural look and feel but requires regular maintenance to prevent rot, insect infestation, and weathering. Popular wood choices include:
- Pressure-Treated Lumber: This is the most affordable option and is resistant to rot and insects. However, it can warp and crack over time and requires regular sealing or staining.
- Cedar: Cedar is naturally resistant to rot and insects and has a beautiful reddish-brown color. It is more expensive than pressure-treated lumber but requires less maintenance.
- Redwood: Similar to cedar, redwood is naturally durable and attractive. However, it is becoming increasingly scarce and expensive.
- Hardwoods (Ipe, Mahogany): These hardwoods are extremely durable and resistant to rot and insects. They are the most expensive option but can last for decades with minimal maintenance.
2. Composite Decking
Composite decking is made from a blend of wood fibers and recycled plastic. It offers several advantages over wood, including:
- Low Maintenance: Composite decking doesn't require staining, sealing, or painting.
- Durability: It is resistant to rot, insects, and fading.
- Consistent Appearance: Composite decking maintains its color and texture over time.
However, composite decking is generally more expensive than wood and can get hot in direct sunlight. Some brands also lack the natural look and feel of real wood.
3. PVC Decking
PVC decking is made entirely from plastic and offers similar benefits to composite decking, including low maintenance and durability. It is also resistant to staining and scratching. PVC decking is typically more expensive than composite decking but may be a good choice for areas with high moisture or heavy use.
4. Framing Materials
Regardless of the decking material you choose, the underlying frame is typically constructed from pressure-treated lumber. Use lumber that is approved for ground contact to ensure longevity and prevent rot. You will also need concrete for the footings.
Tools and Materials List
Having the right tools and materials on hand will make your deck-building project much smoother. Here's a comprehensive list:
Tools
- Measuring tape
- Circular saw
- Drill/driver
- Level
- Post hole digger or auger
- Concrete mixer (optional)
- Hammer
- Safety glasses
- Work gloves
- Square
- String level
- Shovels
Materials
- Pressure-treated lumber for framing (posts, beams, joists)
- Decking material (wood, composite, or PVC)
- Concrete mix
- Deck screws or nails
- Post anchors
- Joist hangers
- Ledger board (if attaching the deck to your house)
- Flashing (to protect the ledger board)
- Stair stringers (if building stairs)
- Railing (optional)
- Wood preservative or stain (if using wood decking)
Calculate the amount of materials you need based on your deck design. It's always a good idea to buy a little extra to account for waste.
Building Your Deck: Step-by-Step
Now comes the exciting part: building your deck! Follow these steps carefully to ensure a structurally sound and aesthetically pleasing result.
1. Preparing the Site
Clear the area where you will be building your deck. Remove any vegetation, rocks, or debris. Level the ground as much as possible.
2. Installing the Posts and Footings
Dig holes for the posts according to your deck design and local building codes. The depth of the holes will depend on your frost line (the depth to which the ground freezes in winter). Consult with your local building department for frost line information.
Pour concrete into the holes and insert the posts, ensuring they are plumb (perfectly vertical). Use post anchors to secure the posts to the concrete footings. Let the concrete cure for at least 48 hours before proceeding.
Tip: Use a string level to ensure that all the posts are at the same height.
3. Attaching the Ledger Board (if applicable)
If you're attaching your deck to your house, you'll need to install a ledger board. This is a piece of pressure-treated lumber that is securely fastened to the house's rim joist.
Before attaching the ledger board, apply flashing to the house wall to protect it from water damage. Use lag screws to attach the ledger board to the rim joist, ensuring they are properly spaced and penetrate deeply into the framing.
4. Installing the Beams and Joists
Attach the beams to the posts using appropriate connectors. The beams will support the joists, which in turn support the decking.
Install the joists perpendicular to the beams, using joist hangers to secure them in place. Ensure that the joists are evenly spaced according to your deck design.
Tip: Use a square to ensure that the joists are perfectly perpendicular to the beams. This will prevent the decking from being crooked.
5. Laying the Decking
Now it's time to install the decking. Start at one edge of the deck and work your way across, leaving a small gap between the boards for expansion and contraction. Use deck screws or nails to fasten the decking to the joists.
Tip: Use a spacer to ensure consistent spacing between the decking boards.
6. Building Stairs (if applicable)
If your deck is elevated, you'll need to build stairs. Use pre-cut stair stringers or build your own from lumber. Attach the stringers to the deck frame and the ground, ensuring they are securely fastened.
Install the stair treads (the horizontal boards you step on) and risers (the vertical boards between the treads), using deck screws or nails.
7. Adding Railing (optional)
Railing is required for decks above a certain height (usually 30 inches) to prevent falls. Install posts around the perimeter of the deck and attach railing sections between the posts. There are many different railing styles to choose from, including wood, composite, and metal.
Finishing Touches
Once your deck is built, add the finishing touches to make it your own.
1. Sealing or Staining (if using wood decking)
If you used wood decking, apply a wood preservative or stain to protect it from the elements. This will help prevent rot, insect infestation, and weathering. Choose a product that is specifically designed for outdoor use and follow the manufacturer's instructions.
2. Adding Furniture and Accessories
Add comfortable seating, a table, and other accessories to create a relaxing and inviting outdoor space. Consider adding:
- Outdoor furniture (chairs, sofas, tables)
- Grill
- Planters
- Outdoor lighting
- Umbrella or awning
- Outdoor rug
3. Landscaping
Surround your deck with plants and flowers to create a beautiful and natural setting. Consider adding:
- Potted plants
- Shrubs
- Trees
- Mulch or gravel
Maintaining Your Deck
Regular maintenance will help keep your deck looking its best and extend its lifespan.
- Clean your deck regularly: Sweep or hose off your deck to remove dirt and debris. Use a deck cleaner to remove stains and mildew.
- Inspect your deck annually: Check for loose screws, cracked boards, and signs of rot or insect infestation. Repair any damage promptly.
- Re-seal or re-stain your deck as needed: Wood decks should be re-sealed or re-stained every one to two years, depending on the type of wood and the climate.
