DIY or Hire a Pro? The Best Way to Install Your Deck

Updated: Jul 14

DIY installation of a Trex composite deck with decking plans.

Building a backyard deck is one of the best ways to add value and comfort to your home. When it’s time to build, you face an important choice: build your own deck or hire a deck contractor?

At first glance, DIY deck installation may appear less expensive. The availability of online tutorials and affordable tool rentals adds to its appeal. Deck construction is complex and can bring unexpected problems.


It requires knowledge of local building codes, permits, safety rules, and the proper use of decking materials. Without experience, DIY projects can be risky and take much longer.

Hiring a professional deck builder or trusted deck building contractor brings skill, faster results, and peace of mind. This article compares DIY and professional options to help you decide what fits your deck project best.


Understanding Deck Installation in Chicagoland

Building a deck is more than putting down boards. It needs careful planning and building know-how. You must also follow legal rules.


Your plan should include:

  • Exact measurements

  • The right materials like pressure treated wood or composite decks

  • Checks to make sure the deck can safely hold weight


You also need to consider:

  • How the deck connects to your home

  • How water drains away

  • The weight your deck will support


In Chicagoland, permits and inspections are required. Ignoring local building codes can cause fines or even having to tear down your deck.

Even minor errors, such as incorrect footing placement or inadequate fastening, can lead to sagging or wood rot.

Professional deck installers understand these risks. They build every quality deck to code, using the right materials and methods for safety and durability.


Pros and Cons of DIY Deck Installation

Pro and Cons of installing a Trex deck DIY, and why you should avoid it.

DIY projects can be rewarding when you possess the necessary skills and adequate time. It might save on labor costs but has hidden expenses like:

  • Buying or renting tools (power saws, post-hole diggers, safety gear)

  • Learning to use a deck design tool

  • Time lost fixing mistakes

  • Risk of costly repairs or failed inspections


Many who try to build their own deck spend more than expected and call deck contractors to fix errors.


Why Hire a Professional Deck Builder?

A professional deck contractor completes the job correctly the first time. Experts deliver a safe, strong, and beautiful deck. Experienced builders have proper licensing and insurance. They follow local building codes and use quality materials - whether a wood deck or composite decks.


They build a level deck with good drainage and secure joists, made for your climate. A professional team completes the project within days, whereas DIY efforts can extend over weeks or months.

They also handle permits and inspections for you. Companies like Warner’s Decking offer warranties on structural issues and materials. This gives you peace of mind long after completion.


Cost Comparison: DIY vs. Professional Contractor in Chicagoland

Building your own deck may seem cheaper at first, but the full costs of DIY deck installation can rise quickly.

According to HomeGuide in Chicagoland:

  • A 12'x12' pressure treated wood deck costs $3,600–$7,200

  • A 20'x20' deck costs $10,000–$20,000

  • Composite decks, like Trex, cost $45–$70 per square foot installed

  • DIY materials alone cost $14–$28 per square foot, excluding tool rentals, time, or mistakes


Professional installation includes labor, materials, cleanup, permits, and inspections. Hiring a deck builder near me costs more upfront but can save money by avoiding errors and rework.


What to Consider Before Deciding

Ask yourself:

  • Do I have the skills and tools?

  • Deck installation needs power tools, exact measurements, and knowledge of framing and drainage.

  • How complex is my deck design?

  • Simple decks might be manageable. Multi-level decks, stairs, custom railings, and lighting require expert craftsmanship.

  • How much time can I spend?

  • DIY projects frequently exceed their planned timelines, while professionals complete work more efficiently and with fewer complications.

  • What is my budget now and later?

  • DIY may reduce initial expenses but often results in costly repairs later. Hiring a deck building contractor reduces waste and surprises.

  • Do I understand local building codes?

  • Permits and inspections are mandatory, and professionals manage these requirements efficiently.


Final Thoughts

Building a deck is rewarding but complex. It needs skill, following local building codes, and time. DIY may save labor but risks safety issues, delays, and costly fixes.

Hiring a professional deck builder or trusted deck contractors ensures your dream deck is safe, sturdy, and built to last. You get expert planning, a custom designed outdoor living space, and peace of mind that your investment adds real value.
