How to Hire the Right Deck Builder

High-Performance Decks Need High-Performance Deck Builders

Hiring the Right Deck Builder

You chose to build your Trex® deck—the one you’ve been dreaming about for years—to be a place where you can unwind or spend time with friends and family, a place you can be proud of. Hiring the wrong contractor can turn your dream project into a costly headache. A qualified deck builder can deliver beautiful results along with peace of mind, so your investment adds lasting value to both your home and leisure time. Choosing wisely from the start can save you money, time and countless frustrations, and this guide will help you make that decision with confidence.

Find a TrexPro® Contractor

Build a Shortlist of Deck Builders

The first step in hiring the right deck professional is to build a shortlist of qualified candidates. A great place to start is with the Trex Find a Builder tool — it’s an easy way to discover vetted local pros who are experienced with Trex products.

As you evaluate these prospects, make sure they align not just with your budget, but also with the style you’re looking for. A contractor whose portfolio reflects the look and feel you have in mind will be far more likely to deliver results that match your vision.

Start Close to Home

Ask friends, family or neighbors who have had decks built if they’d recommend the contractor they used. Seeing a finished project in person and hearing firsthand about the experience offers valuable insight into the quality and reliability of a builder. Another smart strategy is to look around your own neighborhood. If you spot a deck that you admire, don’t hesitate to ask the homeowner who built it—after all, a great deck is something most people enjoy showing off. Contractors already familiar with your community often have a track record you can easily verify.

Asking your local Trex supplier who they recommend is another smart way to find a reputable deck builder. Suppliers benefit from connecting you with contractors who will do quality work, since each successful project enhances their own standing in the community.

Online Sources are Key

Search for deck builders on review platforms, local business directories, and professional networks. When reviewing profiles, focus on details that speak to both quality and stability: years in business, customer reviews, certifications, and photos of past projects. Again, Trex makes this process easier with our Find a Builder tool, which connects you with vetted composite deck contractors experienced in working with Trex products.

Gathering Bids: What to Ask

Once you’ve narrowed your list, it’s time to gather bids. This is where details matter. Always start by requesting proof of an active contractor’s license and general liability insurance. A lack of license and insurance is a red flag. The coverage amounts are important too—adequate insurance protects both you and the builder if accidents or property damage occur. Your own homeowner’s insurance agent should be able to tell you the type of coverage you should look for.

When meeting with prospective contractors, ask them clear, targeted questions about their process, timeline, and experience. But don’t just focus on the answers themselves, pay attention to how they respond. Do they explain clearly? Do they follow up promptly? Professionalism, responsiveness, and a collaborative approach are just as critical as technical know-how. Here is a list of the type of questions you should ask:

Have you built a deck with Trex products before?
What would you describe as your specialty?
Do you have a social media channel or portfolio that would provide more information about the kind of work you do?
Can you help design our deck, or will we need architectural plans?
Can the deck be built in such a way that future upgrades, like hot tubs, outdoor kitchens or gazebos, easier to complete?
Do you handle municipal permitting and HOA approvals?
Do you have references to share?
Can I see examples of decks you’ve completed recently?
What does your payment schedule look like?
Who will be on-site managing the project day to day?
When can you start?
How long will it take?
Will you provide a detailed written proposal with materials, scope of work and timeline?

Compare Proposals

After gathering bids, you’ll want to look closely at the proposals. A thorough proposal should outline the scope of work, including a materials list that specifies decking, railing, fasteners and any additional features. Look for detailed construction plans that show the deck footprint, railings, stairs and any built-in elements like seating or lighting. In addition to price, here are other items to look for in a proposal, all of which should always be included in a formal contract:

Start and completion dates (or ranges): These keep your project on schedule.
Warranties: Both on workmanship and materials.
Change-order process: A written procedure for approving and pricing any modifications along the way.
Payment schedule: Clearly defined installments tied to project milestones, rather than large upfront payments.
Site responsibilities: Details about start times, cleanup, debris removal and restroom facilities if needed.
Subcontractors: Clarification of whether subcontractors will be used and who is responsible for supervising them.
Insurance verification: Documentation showing active insurance policy.
Permits and inspections: Agreement on who will secure permits and schedule required inspections.
Dispute resolution: A process for resolving conflicts should disagreements arise.

These elements not only protect you but also set clear expectations, minimizing the chance of costly or stressful surprises. And remember, price shouldn’t be the only deciding factor. You should feel confident in the builder’s professionalism, comfortable with their communication style and assured that they understand your vision for the project.

Red Flags to Watch Out For

Hiring a deck builder is a big decision, and unfortunately not every contractor has your best interests at heart. Even the most polished sales pitch can mask inexperience, corner-cutting, or worse. That’s why it’s essential to recognize warning signs early. Ignoring them can lead to wasted money, months of delays, and a deck that looks bad or feels unsafe. Keep an eye out for these common red flags when evaluating contractors:

Requests for cash-only payments: Without a paper trail, you have little recourse if problems arise.
Vague or verbal-only estimates: Always insist on a written proposal with clear details.
High-pressure sales tactics: No contractor should rush you into a decision, especially on a major investment.
Missing or expired insurance: Lack of active coverage puts both you and your property at risk.
Unwillingness to provide references: Reputable contractors should be eager to connect you with past customers.
No license or unclear credentials: Verify their license is valid and up to date.
Unrealistically low bids: If the price seems too good to be true, it could mean subpar materials or hidden costs later.
Poor communication: Slow responses or vague answers during the bidding process can foreshadow bigger issues once work begins.

Spotting even one of these warning signs is reason enough to pause, dig deeper or walk away. A trustworthy builder will welcome your questions, provide documentation without hesitation and prioritize your confidence as much as the quality of your deck.
