Adding a deck to your home can increase your living space and provide an outdoor oasis for relaxing and entertaining. However, building a deck is a major project that requires careful planning and execution. This comprehensive guide will walk you through the entire process of designing, planning, and constructing a deck.
Planning Your Deck
The first step is deciding what you want to achieve with your deck. Consider the following:
Location
Think about where the deck will be situated on your property. Decks are often built off the back of a house, but side and front yard decks are options, too. Make sure the location is feasible for deck footings and allows access from your home.
Size
Determine the deck’s dimensions based on the space available and how you want to use it. Typical residential decks range from 200 to 700 square feet. Make sure to check building codes for size restrictions.
Height
The deck can be ground-level or elevated, depending on your needs. Ground-level decks have a height of only a few inches off the ground. Elevated decks range from 1-4 feet high but can be higher. Consider views, accessibility, safety, and comfort when choosing the height.
Purpose
How will you use your deck? For casual dining? Entertaining large groups? A serene spot for reading? Let your intended use guide elements like the size, location, railings, and steps.
Budget
Deck building involves materials, tools, permits, and labor costs. Most wooden decks cost $25-$50 per square foot, or $5,000-$35,000 total. Have a budget in mind before starting the design.
Style
Select a deck style that fits your home’s architecture and aesthetic. Rustic wood and natural tones work well with craftsman homes, while straight lines suit modern spaces. Also, consider specialized decking like curved, multi-level, or roof deck designs.
The Right Tools
Building a deck requires an assortment of tools. Essential equipment includes:
- Circular or miter saw
- Power drill/driver
- Hammer
- Level
- Tape measure
- Framing square
- Safety gear – gloves, glasses, etc.
You may also find the following tools useful:
- Jigsaw
- Reciprocating saw
- Hole saw
- Brad nailer
- Ratchet wrench
- Line level
- String line
Rent or borrow any specialty tools you may need for a short period.
Designing Your Custom Deck
With a vision in mind, map out deck plans. Good design distributes weight properly, facilitates water drainage, and minimizes installation issues.
Sketch the Layout
Draw your deck to scale, showing the shape, dimensions, location of stairs/railings, and spacing between decking boards. Photograph the site and use graph paper to neatly draw plans from overhead and side views.
Choose Materials
Select decking boards, posts/beams, fasteners, and railing styles. Popular decking materials include pressure-treated lumber, cedar, composite, aluminum, and vinyl. Choose materials suitable for your climate that are within budget.
Account for Setbacks and Permits
Determine the required setbacks from property lines per local zoning laws. Many areas require permits for decks over 200 square feet. Include setbacks in plans and prepare to pull permits.
Outline Construction Details
Illustrate framing plans showing floor joists, blocking, and post spacing. Include details like stairs, railings, benches, lighting, and drainage. These drawings are important for permits and contractor estimates.
Preparing for Construction
With a detailed deck design complete, finalize preparations to allow construction to proceed smoothly.
Clear the Area
Remove trees, bushes, stumps, or debris from the site. Having an empty flat workspace minimizes delays once the building begins.
Install Footings
Dig holes for concrete pier footings per code at least 42 inches deep. Pour concrete and allow time to cure fully so post-installation can be properly supported.
Order Materials
Use finalized plans to make a shopping list of all required decking materials and hardware. Order everything well in advance of the build date.
Secure Permits
Submit official plans to your local permitting office. If approved, they will issue a building permit allowing legal construction. Read all codes carefully to ensure compliance.
Hire a Contractor
Unless you’re an experienced DIYer, hiring a professional deck builder is recommended to ensure proper structural engineering and artistry. Get references and contract bidding from multiple deck contractors.
Building Your Deck
Once preparations are complete, it’s time to start construction. Proper process is crucial for a safe, functional, long-lasting deck.
Set Posts
Dig holes for concrete pier footings at least 42 inches deep per code. Pour concrete and allow full curing time. Install deck posts secured to anchor bolts on cured footings.
Install Floor Joists
Measure and cut floor joist boards to span from ledger board to rim joist. Use galvanized joist hangers to attach ends. Gap correctly for drainage and fastener clearance.
Ad Blocking
Cut shortboards to fit tightly between joists every 4-6 feet. Nail blocking between joists for stability and to attach railings later. Leave gaps for drainage.
Install Decking
Measure and cut decking boards. Gap them correctly for drainage without leaving trip hazards. Fasten with hidden fasteners or screws. Stagger boards attractively.
Build Stairs
Cut stringers to proper rise/run ratio and fasten securely to posts. Install treads and risers, leaving small gaps for drainage. Use proper stair rails for safety.
Add Railings
Measure and cut posts and balusters to length. Attach railing posts securely at the deck edge. Install upper and lower rails, maintaining spacing between balusters for safety.
Include Finishing Touches
Add benches, planters, lighting, or other touches, making sure they don’t impede drainage. Stain or seal the deck if desired after letting the wood dry completely.
Inspect and Enjoy
The building inspector will visit to check code compliance and structural soundness before signing off. Once approved, furnish your completed deck and enjoy your new outdoor space!
Maintaining and Protecting Your Deck
Building the deck is only part of the process. Proper maintenance and care are required to keep your deck looking great and extend its lifespan. Here are some tips for protecting your investment:
Clean and Seal Regularly
Sweep away debris between deck boards frequently. Deep clean the deck at least twice per year using a pressure washer or wood cleaner to remove stains. Apply water-repellent sealant yearly to protect the wood from water damage, mold, and UV rays.
Inspect for Damage
Walk your deck to look for issues monthly. Check for damaged boards, loose joints, cracked wood, or corrosion on fasteners. Make all needed repairs immediately to prevent bigger problems down the road.
Protect Against Moisture
Ensure proper drainage under the deck to prevent moisture issues. Keep gutters and downspouts clear and allow adequate airflow under the deck. Let the wood dry out between rains before sealing or staining.
Check for Mold and Mildew
Dampness on horizontal surfaces can allow mold and mildew growth. Remove it immediately with chlorine bleach or hydrogen peroxide cleaner. Improve drainage and air circulation to prevent recurrence.
Monitor for Pests
Carpenter bees, termites, and ants can damage wood decks. Watch for signs of infestation and treat using pesticides if needed. Keep wood properly sealed and dried out to deter pests.
Adjust Decking as Needed
Wood expands and contracts with changes in moisture and temperature. Expect slight gaps between boards to open or close seasonally. Re-seal open gaps when needed.
Tighten Hardware
Vibration and wood movement can loosen bolts, screws, nails, and hangers over time. Check connections yearly and tighten or replace hardware as needed to avoid safety hazards.
Plan for Repairs
Decks have a lifespan of 10-15 years on average. Budget for periodic repairs or partial rebuilding to keep your deck functional and looking its best.
Consider Refinishing
If discoloration or wear detracts from the deck’s appearance over time, refinishing can renew its look. Sand thoroughly and re-stain or paint to match your home’s updated exterior colors.
Watch for Structural Issues
Signs like major wood cracking, post-leaning, and floor sagging can indicate a loss of structural integrity. Have an expert inspect and make repairs to prevent collapse or property damage.
Ideas for Customizing Your Deck
Part of the fun of owning a deck is customizing it to suit your lifestyle needs perfectly. Here are some creative ideas for making your deck unique:
Incorporate Multi-Level Sections
Break up a large single-level deck by incorporating raised and lowered sections for visual interest. Connect levels with attractive steps or ramps. Multi-level decks add architectural flair while maximizing views and space.
Include a Food Prep Area
Install a countertop, cabinetry, sink, mini-fridge, or grill to create a functional outdoor kitchen space. Add seating at a built-in bar area so guests can relax near the chef. Choose materials made for outdoor use.
Add Overhead Shade Elements
Drop shade sails, installed pergolas, or retractable awnings allow you to control sun exposure on very hot or bright days. You can enjoy the deck for more hours of the day with strategic shade elements.
Install Deck Lighting
Outdoor light fixtures provide ambiance for nighttime use and highlight architectural deck features. Consider path lighting, post-mounted lanterns, color-changing LEDs under railings, or recessed stair lights.
Build-in Planters and Greenery
With built-in or movable planters, you can enjoy flowers, herbs, and other plants while on your deck. Hanging baskets also bring natural beauty. Just ensure proper drainage underneath.
Include a Water Feature
The pleasant sights and sounds of flowing water enhance outdoor relaxation. Install a mounted fountain or build a small waterfall into the side of an elevated deck. Just check safety codes first.
Add Specialty Flooring
Accent your main deck boards with stone, tile, pavers, or colorful composite inlays. Create decorative borders, geometric patterns, or an emblem with contrasting flooring materials.
Outfit with Privacy Features
Lattice panels, screening, retractable sun shades, or strategically placed planters allow you to control visibility and access as desired. It’s easy to increase privacy on public-facing decks.
Personalize with Decor
Make the space your own with outdoor area rugs, throw pillows, hanging art, strings of lights, wind chimes, or other decorative accents compatible with weather exposure. Change decor seasonally.
Your deck’s intended purpose, location, and architectural style will guide the accessories and custom features that are most appropriate. Whether keeping it simple or getting fancy, make your deck distinctly yours.
Common Deck-Building Mistakes to Avoid
It’s easy for deck-building projects to go wrong, even with the best-laid plans. By being aware of common pitfalls ahead of time, you can avoid them on your deck. Here are important mistakes to steer clear of:
Insufficient Footings
Footings that are too shallow, spaced too far apart, or improperly cured lead to structural instability. Dig pier holes to the depth specified in building codes before pouring concrete.
Improper Joist Spacing
Floor joists must be spaced according to deck load requirements. Wider spacing saves money on materials, but risks sagging or collapse. Stick to code spacing.
Inadequate Beam Support
Beams require a footing and post to provide proper support. Never attach them unsupported to only the side of the house or rest on top of posts alone.
Not Allowing for Drainage
Flat decks don’t allow water drainage between boards, which leads to pooling, mold, and rot. Always include a slight pitch for drainage when planning and building.
Skipping Required Permits
Building decks without required permits risk fines, tear-down orders, and denial of homeowners insurance claims if problems occur. Always check permit rules.
Rushing Concrete Curing
Allow concrete footings to cure for the required days specified per manufacturer instructions. Bolting posts too early will destabilize the structure over time.
Gapping Deck Boards Incorrectly
Decking gaps that are too wide look bad and catch heels. Spacing too narrow prevents drainage. Carefully gap according to decking manufacturer guidelines.
Using the Wrong Fasteners
Regular nails and screws quickly corrode outside. Invest in galvanized, stainless steel, or coated decking fasteners for longevity. Never use unrated fasteners.
Incorrect Railing and Stair Construction
Improperly spaced balusters, short railing posts, and stair treads at the wrong angle or spacing are hazards. Closely follow code requirements for safety.
Not Sealing Wood
Leaving wood unsealed exposes it to moisture damage, rot, and pests. Always use a recommended sealing product after installation and reapply as directed.
Building a deck is ripe with chances for error. Careful planning, double-checking measurements, and adherence to building codes will help you avoid costly mistakes that compromise safety and durability. Consult a professional if any part of the process proves unfamiliar or overwhelming.
