You’ve made it this far. You know decking will transform your outdoor space. You’ve chosen your contractor. Now you’re standing at the exciting threshold of turning your vision into reality.
This is the moment when anticipation meets action. Soon, you’ll be sipping your morning coffee on your new deck, hosting weekend BBQs with friends, or simply enjoying Perth’s beautiful evenings in your own outdoor retreat.
But before the first board is cut, there are some final steps that separate successful projects from disappointing ones. This guide will help you cross the finish line with confidence, ensuring your deck project delivers everything you’ve dreamed of—and more.
The difference between a good deck project and a great one often comes down to the details you sort out in these final weeks. From understanding exactly what’s included in your contract to exploring exciting upgrade options that will make your space truly special, every decision you make now will impact your enjoyment for years to come.

Before we dive into the final details, let’s quickly reaffirm why hiring a professional deck builder was the right call. The temptation to save money with DIY is real, but the hidden costs and risks make professional installation the smart choice for most Perth homeowners.
| What Matters Most | DIY Reality | Professional Delivery | Long-Term Impact |
| Time to Completion | 2-4 months of weekends | 1-3 weeks total | Enjoy your deck this season |
| Quality Assurance | Learning as you go | Decades of experience | No costly repairs later |
| Structural Safety | Hope it’s built right | Engineering expertise | Peace of mind always |
| Weather Protection | Fingers crossed | Perth climate knowledge | Deck lasts for decades |
| Problem Solving | YouTube and stress | Immediate solutions | Smooth project flow |
| Final Result | “Good enough” | “Better than expected” | Adds real property value |
| Warranty Coverage | You fix everything | Comprehensive protection | Protected investment |
Many homeowners underestimate the true cost of DIY decking. Here’s what the numbers really look like:
| Cost Category | DIY Reality | Professional Advantage |
| Tool Purchase/Rental | $2,000-$4,000 | Included in service |
| Material Waste | 15-20% over-ordering | Precise quantities |
| Permit Mistakes | $500-$2,000 in fees/delays | Handled expertly |
| Structural Errors | $3,000-$8,000 to fix | Built right first time |
| Time Value | 60-120 hours of your time | Your weekends back |
| Stress Factor | Immeasurable | Eliminated |
You’ve chosen expertise over experimentation. Now let’s make sure you get the most from that investment.
The weeks before construction begins are crucial. This is when you’ll finalize every detail, avoid common pitfalls, and set expectations that ensure a smooth building process.
Perth’s unique climate and local regulations mean your deck needs to meet specific standards. Here’s what your contractor should be handling:
| Requirement Type | Perth Specific Considerations | Why It Matters |
| Wind Loading | Coastal winds up to 100km/h | Structural integrity |
| Bushfire Ratings | BAL ratings in some areas | Safety and insurance |
| Drainage Standards | Heavy winter rainfall | Prevents water damage |
| Setback Requirements | Varies by suburb | Avoids council issues |
| Height Restrictions | Different for each council | Prevents demolition orders |
At this stage, your material choices should be locked in. But it’s worth understanding exactly what you’re getting:
Premium Hardwood Options for Perth:
| Timber Type | Durability Rating | Maintenance Needs | Perth Climate Suitability | Cost Factor |
| Jarrah | ★★★★★ | Low-Medium | ★★★★★ | High |
| Spotted Gum | ★★★★★ | Low-Medium | ★★★★★ | High |
| Blackbutt | ★★★★☆ | Medium | ★★★★☆ | Medium-High |
| Merbau | ★★★★☆ | Medium-High | ★★★★☆ | Medium-High |
| Treated Pine | ★★★☆☆ | High | ★★★☆☆ | Low |
Composite Decking Comparison:
| Brand Category | Heat Resistance | Fade Resistance | Warranty Period | Perth Suitability |
| Premium Composite | Excellent | 25+ years | 25-30 years | ★★★★★ |
| Mid-Range Composite | Good | 15-20 years | 15-20 years | ★★★★☆ |
| Budget Composite | Fair | 10-15 years | 10-15 years | ★★★☆☆ |

You’re almost there, but these final steps determine whether your project runs smoothly or hits unnecessary bumps. The contract you sign and the details you confirm now will govern every aspect of your project.
Before you sign anything, ensure these elements are explicitly detailed. A good contract protects both you and your contractor by setting clear expectations.

Financial Terms:
Beyond the basics, these questions reveal your contractor’s professionalism and expertise:
About Project Management:
About Quality Control:
About Problem Resolution:
Your contractor should handle permits, but understanding the process helps you stay informed and avoid delays:
| Permit Type | When Required | Processing Time | Cost Range | Your Role |
| Building Permit | Decks over 1m high or attached | 2-6 weeks | $200-$800 | Provide property details |
| Development Approval | Large decks, heritage areas | 4-8 weeks | $500-$2,000 | Sign applications |
| Structural Certification | Complex or elevated decks | 1-2 weeks | $800-$2,000 | Review and approve plans |
| Electrical Permit | Adding power/lighting | 1-2 weeks | $150-$400 | Specify requirements |
| Plumbing Permit | Water features or drainage | 2-3 weeks | $200-$600 | Approve connections |
Before construction begins, ensure these items are addressed:
Access and Logistics:
Utilities and Services:

Even at this final stage, small oversights can create big problems. Learning from others’ mistakes can save you time, money, and stress.
The Problem: Assumptions about what’s included lead to disputes later. “I thought the stairs were included” is a common source of tension.
The Solution: Get everything in writing. If it’s not in the contract, it’s not included. Create a detailed scope document that covers every element.
Red Flag Examples:
Prevention Strategy: Ask your contractor to walk through the entire scope item by item, ensuring every component is documented.
The Problem: Materials can’t reach your backyard, causing delays and extra costs for manual handling or crane hire.
The Solution: Walk through access routes with your contractor before work begins. Measure gate widths, check overhead clearances, and plan protection for existing surfaces.
Consider These Factors:
The Problem: “While you’re here” additions that blow budgets and timelines. Small changes can have big impacts on structural requirements and material orders.
The Solution: Finalize all design decisions before construction begins. Create a formal change approval process for any modifications.
| Change Type | Cost Impact | Schedule Impact | Material Impact | Best Time to Decide |
| Material Upgrade | 10-30% increase | Minimal delay | May need reordering | Before ordering |
| Size Increase | 15-40% increase | 1-2 week delay | Significant changes | Design phase |
| Added Features | Varies widely | 3-7 day delay | Additional materials | Planning stage |
| Layout Changes | 20-50% increase | 1-3 week delay | Complete reorder | Never during construction |
| Electrical Additions | $500-$2,000 | 2-5 day delay | New permits needed | Early planning |
The Problem: Unclear payment terms create tension and cash flow issues. Know exactly when payments are due and what triggers them.
The Solution: Understand the payment schedule and ensure it’s tied to completed milestones, not just time passing.
Industry Standard Schedule:
The Problem: Perth’s weather can impact construction schedules, especially during winter months or extreme summer heat.
The Solution: Understand how weather affects your project timeline and build in realistic buffers.
| Weather Condition | Impact on Construction | Typical Delays | Prevention Strategies |
| Heavy Rain | Stops most outdoor work | 1-3 days | Covered work areas |
| Extreme Heat (40°C+) | Limits work hours | Half days | Early morning schedules |
| Strong Winds | Unsafe for elevated work | 1-2 days | Flexible scheduling |
| Extended Wet Period | Can’t excavate or concrete | 1-2 weeks | Weather monitoring |

Now for the fun part! These popular additions can elevate your deck from functional to phenomenal. Since you’re already investing in professional construction, now is the perfect time to consider these enhancements.
