DIY vs. Hiring a Pro: Why Deck Installation Is Best Left to the Experts

Building a backyard deck is one of the best ways to add value and comfort to your home. But when it’s time to make it happen, you’ll face a big decision: should you build it yourself or hire a professional?

DIY projects can seem like a good way to save money, especially with online tutorials and tool rental options. But deck installation isn’t a typical weekend job. It involves structural planning, building permits, and safety codes—things that aren’t so simple without experience.

Hiring a professional deck builder means you get expert craftsmanship, faster completion, and peace of mind that everything is built to last. In this article, we’ll compare DIY vs. professional deck installation, break down the risks and rewards, and help you decide which option is right for your home.​

Understanding the Scope of Deck Installation

Building a deck involves far more than laying down boards. It is a full-scale construction project that requires careful planning, structural knowledge, and legal compliance.

Before the first board is installed, homeowners must develop a detailed plan that includes accurate measurements, appropriate materials, and clear load-bearing calculations. The design must account for how the deck will connect to the home, how it will drain, and what kind of weight it must support.

You will also need to research local building codes, apply for a permit, and schedule inspections at key phases of the build. These codes are in place for safety, and ignoring them can lead to fines, failed inspections, or forced demolition.

Even small mistakes can create serious problems. Poorly placed footings may cause sagging or uneven surfaces. Improper fasteners or spacing can lead to rot, instability, or premature failure. In some cases, a deck that appears solid may still be structurally unsound.

Professional contractors understand these risks and build every deck to meet local code requirements. They are trained to anticipate issues, use proper materials, and ensure long-term structural integrity.

Pros and Cons of DIY Deck Installation

Benefits of Hiring a Professional Deck Builder

Hiring a pro means getting your deck done right the first time. It’s not just about saving time—it’s about building something that lasts, looks great, and adds real value to your home.

Experienced builders are familiar with the codes, materials, and structural techniques that ensure a deck is safe and sturdy. They understand how to slope for optimal drainage, secure joists properly, and select the appropriate fasteners for their climate. That’s not stuff you want to guess on.

They also work faster. A job that might take you several weekends can be done by a crew in a few days, without sacrificing quality.

And most importantly, pros handle permits and inspections for you. No confusing paperwork, no failed inspections—just a smooth path to enjoying your new space.

Bonus: Professional builders, such as Warner's Decking, offer warranties on both labor and materials, giving you peace of mind long after the last board is laid.

Cost Analysis: DIY vs. Professional Installation in Chicagoland

At first glance, building your own deck may seem like the more budget-friendly option. But when you break down the full scope of materials, tools, labor, and potential rework, the numbers tell a different story.

According to HomeGuide, the average cost to build a new deck in Chicagoland ranges from $25 to $50 per square foot, depending on the material and design complexity. For example:

A 12'x12' pressure-treated wood deck costs between $3,600 and $7,200

A 20'x20' deck may run $10,000 to $20,000

Composite decks, including brands like Trex, range from $45 to $70 per square foot installed

DIY: Hidden Costs Add Up

If you choose to build a deck yourself, you’ll save on labor but take on every other cost—and risk:

• Materials only: $14 to $28 per square foot

• Tool rental or purchase: power saws, drills, levels, post-hole diggers, safety gear

• Time: weekends lost to trial, error, and corrections

• Potential mistakes: structural issues, misaligned boards, or failed inspections that could require professional rebuilding

Homeowners who take the DIY route often find themselves spending $2,000 to $4,000 just on a small 12'x12' deck, not including the value of their time. And if something goes wrong, the cost of repairs or rework can easily push total expenses beyond the cost of professional installation.

Professional Installation: Higher Upfront, Lower Risk

Hiring a licensed contractor includes:

• Labor, materials, and cleanup

• Permit handling and inspection scheduling

• Precision installation that meets code

• Warranty coverage on materials and craftsmanship

Although professional installation in Chicagoland typically costs more upfront, it provides long-term value by avoiding the risks that come with improper footing placement, drainage problems, or unsafe framing. You also benefit from faster completion times, especially for multi-level or custom decks.

DIY may appear more affordable on the surface, but when you factor in labor, equipment, material waste, and potential rework, it can become more expensive than hiring a pro. A professional deck builder delivers peace of mind, structural reliability, and a finished product that adds value to your home.

Key Considerations Before Making a Decision

Before you commit to building your deck yourself or hiring a contractor, take a moment to consider the following questions:
Do you have the right skills and tools?	Deck installation requires power tools, advanced measuring techniques, and knowledge of structural framing, drainage, and safety standards. Mistakes can be costly if you're inexperienced.
How complex is your deck design?	Basic platforms are manageable, but projects with multiple levels, stairs, custom railings, or lighting need expert planning and precision. These features are not recommended for beginners.
How much time can you realistically commit?	DIY projects can stretch over weekends or months. Limited time or experience can make tasks overwhelming, while professionals can usually complete decks in a few days.
What’s your budget now—and later?	DIY may seem cheaper at first, but repairs and mistakes can add up. Hiring a professional brings efficiency, reduces material waste, and limits unexpected expenses
Do you understand your local building codes?	Permits, inspections, and structural guidelines are often required. Mistakes can result in fines, delays, or required demolition. Professionals typically handle the entire process.

Final Thoughts

Building a deck might seem like a rewarding challenge, but the reality is that it’s a complex construction project that demands technical skill, code compliance, and significant time. While DIY can save on labor, it often leads to costly setbacks, safety issues, and ongoing repairs that could have been avoided.

Hiring a professional deck contractor ensures your project is done correctly from the start. You get expert planning, quality craftsmanship, and a structure that not only looks great but meets local building standards. More importantly, you protect your home, your budget, and your peace of mind.

Frequently Asked Questions

Can I build a deck myself and still pass inspection?

Yes, but passing inspection as a DIY builder requires strict adherence to local building codes. You must correctly install footings, joists, railings, and hardware—all while using approved materials. Even experienced homeowners often miss critical code requirements, which can result in failed inspections or costly corrections. Hiring a professional improves the chances of passing inspection the first time, avoiding delays, penalties, or required rebuilds.

Is hiring a professional deck builder worth the extra cost?

In most cases, yes. A professional builder offers structural expertise, proper permitting, efficient timelines, and warranty protection. While the upfront cost is higher, you reduce the risk of hidden expenses related to errors, inspection failures, or future repairs. You also gain peace of mind knowing the job is done right.

Does Warner’s Decking handle permits and inspections?

Yes. Warner’s Decking manages the entire permitting process, schedules inspections, and ensures your deck complies with all applicable local codes. This saves you time and eliminates the risk of delays or fines due to missing paperwork or failed inspections.

How much more does professional installation typically cost compared to DIY?

While pricing varies by project size and materials, professional installation often costs 30–50% more than the raw material cost of a DIY build. However, this includes labor, equipment, cleanup, and expertise. It also prevents costly rework or structural issues, which can make DIY more expensive in the long run.
