1. Plan Your Deck Design
Before buying materials or starting construction, define:
- Purpose: Entertaining, dining, or quiet relaxation
- Size and Shape: Consider available yard space and local setback requirements
- Style: Raised, multi-level, or ground-level decks that complement your home’s architecture
- Budget: Include materials, labor, and permits
2. Choose the Right Materials for Coastal Living
Cape Cod’s coastal environment demands weather-resistant decking materials:
Wood Options:
- Cedar or Redwood: Naturally resistant to rot and insects, classic appearance
- Pressure-treated Lumber: Affordable and durable, requires regular maintenance
Composite Options:
- Composite Decking: Low-maintenance, long-lasting, resists warping, splintering, and fading
- PVC Decking: Fully synthetic, ideal for high-moisture environments
3. Check Local Permits and Building Codes
Before construction, check with your town or city building department:
- Obtain a deck permit if required
- Comply with setback, height, and railing regulations
- Ensure structural plans meet local building codes for wind and snow loads
4. Prepare the Site
Site preparation ensures a stable, level foundation:
- Clear vegetation and debris
- Mark deck boundaries with stakes and string
- Level the ground or slope slightly for drainage
- Dig post holes to code-specified depth (usually below the frost line)
5. Build the Frame and Posts
- Install posts securely into footings
- Construct the ledger board attached to your home’s structure
- Add joists for structural support
- Ensure the frame is level and square before adding decking
6. Install Decking Boards
- Lay decking boards perpendicular to joists
- Leave small gaps between boards for drainage
- Secure boards with screws or hidden fasteners for a clean finish
- Trim edges neatly for aesthetic appeal
7. Add Railings and Stairs
- Railings provide safety and style — choose materials that match your deck
- Follow building code for height, spacing, and baluster design
- Construct stairs with proper rise and run for comfort and safety
8. Finishing Touches and Maintenance
- Apply sealant or stain for wood decks to protect against UV and moisture
- Inspect all fasteners and joints regularly
- Clean composite or PVC decks with mild soap and water annually
