A well-built deck transforms your outdoor space into a functional, beautiful extension of your home. But if the job is rushed or handled by an inexperienced contractor, you could end up with safety hazards, costly repairs, or a structure that doesn’t meet Washington’s strict building codes. Choosing the right deck contractor is essential. To help you make an informed decision, here are five crucial questions to ask before signing any agreement.
If you’re looking for quality deck installation for homeowners in Washington state, these questions can help you avoid common pitfalls and hire the right professional for your project.
1. Are You Licensed, Bonded, and Insured in Washington?
This is non-negotiable. A legitimate deck contractor should have:
- A Washington State Contractor License (check status at lni.wa.gov)
- Bonding, which protects you financially if the contractor fails to complete the job
- General liability insurance, which covers damage to your property
- Workers’ compensation, which protects you from liability if a worker is injured on your property
Always ask for proof. A contractor who hesitates to provide documentation is a red flag.
2. What Type of Materials Do You Recommend and Why?
The Pacific Northwest’s damp, often unpredictable weather makes material selection critical. Ask the contractor which materials they typically use and why. For example:
- Pressure-treated lumber is affordable but requires ongoing maintenance.
- Cedar or redwood offers natural beauty and resistance to rot but comes at a higher price.
- Composite decking (like Trex or TimberTech) is low-maintenance and long-lasting—perfect for wet climates.
An experienced contractor should recommend materials that balance your budget, aesthetic goals, and long-term maintenance needs.
3. Can You Provide References and a Portfolio of Recent Projects?
A reputable contractor will gladly share examples of past work and client testimonials. Ask for:
- Photos of completed decks (especially ones similar to your design or size)
- At least three references from recent projects
- Reviews on platforms like Google, Houzz, or Yelp
Follow up with these references and ask about professionalism, communication, project timeline, and final results.
4. What’s Included in the Written Estimate?
Before committing, you need a detailed, itemized quote. It should include:
- Labor and material costs
- Permitting fees
- Cleanup and disposal
- Timeline with milestones
- Payment schedule
Ask if anything may incur additional charges and how changes to the plan are handled.
If you’re planning to work with a reliable deck installation contractor, transparency in pricing and scheduling is a key indicator of professionalism and accountability.
5. Do You Handle Permits and Understand Local Building Codes?
Every city or county in Washington has specific regulations for deck construction, including:
- Setbacks and property lines
- Railing height and spacing
- Joist and beam sizing
- Structural anchoring requirements
A seasoned contractor should be familiar with the permitting process and take responsibility for securing permits. They should also schedule necessary inspections to ensure the deck complies with safety and zoning laws.
Bonus Tip: Ask About Warranties
Ask what warranties are available for both labor and materials. Many decking manufacturers offer 25–50-year limited warranties, and a quality contractor will often provide their own workmanship guarantee.
Final Thoughts
Your deck should be a safe, stylish, and durable addition to your home—not a source of stress or regret. By asking the right questions before hiring, you’ll feel confident you’re getting expert craftsmanship, proper materials, and a smooth building process from start to finish.
Whether you’re envisioning a simple platform or a multi-level outdoor retreat, choosing the right contractor is the first step toward a beautiful and lasting result.
