What to Look for When Hiring a Contractor in King County

The most common way homeowners evaluate contractors is also one of the most incomplete: they get a few bids, go with the lowest number, and maybe check the reviews after the fact to feel better about the decision. Price and reviews both have a place in the process — but leading with them means you can end up hiring the wrong contractor for the right price, or screening out some of the most qualified people before you've learned a single verifiable fact about them.

The Problem with Leading on Price and Reviews

Price is a real consideration — nobody is pretending otherwise. But in construction, a low bid is often low for a reason. Missing insurance. No permit budget. Cut-rate subcontractors. Shortcuts that won't be visible until years down the road. The bid comparison only means something if the bids are actually comparable — same scope, same materials, same standards. And you can't know that without doing some homework first.

Reviews have a different problem. A contractor who has been in business for 15 years has had 15 years to accumulate Google reviews. A contractor who launched two years ago — even one who is fully licensed, bonded, insured, and doing exceptional work — simply hasn't had the volume of completed projects to build a comparable review count. If you filter by star rating or minimum review count, you've already eliminated them from consideration before you've learned a single meaningful thing about their actual qualifications.

The same applies to portfolio photos. A newer business may only have a handful of completed projects to show. That doesn't mean the work is poor — it means the business is new. Those are very different things. Price and reviews are both worth considering, but neither one tells you whether the contractor is licensed, bonded, and accountable. That information is freely available in Washington State — and it should always come first.

⚖️ A Note on Context

None of this is an argument against reviews or portfolios. A contractor with 200 consistently positive reviews about communication, timeliness, and quality is a meaningful signal. A thin portfolio from a business that has been operating for a decade is a different kind of signal. The point is to use these inputs as context, not as a sorting filter that eliminates candidates before you've checked a single verifiable fact.

The verifiable facts — license, bond, insurance — are freely available in Washington State in about two minutes. Start there. Reviews and photos come after.

What Actually Matters: A Practical Framework

Here's how we'd approach hiring a contractor in King County if we were homeowners — organized from the things you can verify objectively to the things you assess through direct interaction.

01

Verify the License, Bond, and Insurance — Before Anything Else

In Washington State, every construction contractor is required to be registered with the Department of Labor & Industries (L&I), carry a surety bond, and maintain general liability insurance. This is not optional, and it's not just paperwork — it's the legal and financial infrastructure that protects you if something goes wrong. A licensed contractor operates under a registration that can be verified, suspended, or revoked. An unlicensed one has no such accountability. Before you read a single review or look at a single photo, look up the contractor on L&I's free verification tool. The license either exists or it doesn't. There's no gray area.

✓ Verifiable in 2 minutes
02

Check for Complaints or Bond Claims — Not Just Star Ratings

The L&I lookup doesn't just confirm a license exists — it shows you whether there are any lawsuits filed against the contractor's bond, any safety citations, and the status of their workers' compensation account. A contractor with a five-star Google rating but an active bond claim is a different picture than their reviews suggest. Conversely, a newer contractor with few reviews but a clean L&I record is someone worth a conversation. Bond claims and citations are the kind of documented, substantiated problems that reviews often don't capture — and they're right there in the public record.

✓ Verifiable via L&I
03

Ask for a Written Scope and Itemized Quote

Any contractor worth hiring will give you a written scope of work and an itemized quote before a contract is signed. Not a ballpark. Not a verbal commitment. A document that describes what is being done, what materials are being used, and what it costs — broken down in enough detail that you can compare it against other bids meaningfully. This protects you from scope creep, budget surprises, and the classic "that wasn't included" conversation mid-project. If a contractor resists putting specifics in writing, that resistance is telling you something important.

→ Ask for it upfront
04

Confirm They'll Pull the Required Permits

Permits exist so that someone with no stake in the outcome — a city or county inspector — verifies that the work was done correctly before it's closed up behind walls. A contractor who suggests skipping permits is either trying to cut costs at your expense, avoid scrutiny of their work, or both. Unpermitted work can create serious problems when you sell your home, when you file an insurance claim, or when the work fails. In King County, permit requirements are specific and well-documented. A legitimate GC will know which permits are required for your project and pull them as a matter of course — not as a favor.

→ Ask directly
05

Understand Who Is Actually Doing the Work

General contractors typically manage and coordinate projects — they don't always perform every trade themselves. That's normal and appropriate. What you want to understand is whether the subcontractors they use are also licensed and insured, and whether the GC takes responsibility for their work. A good GC has a network of vetted, trusted trade partners they work with consistently. What you want to avoid is a GC who wins the job and then essentially re-bids it to whoever is cheapest that week, with no established relationship or quality standard. Ask who specifically will be on your job and what their relationship is to the GC.

→ Ask about their team
06

Ask About Change Orders Before They Happen

Every significant remodel has surprises. Opening a wall sometimes reveals something unexpected — old wiring, water damage, structural issues that weren't visible during the initial walkthrough. The question isn't whether change orders will happen. It's how they're handled when they do. A good contractor will explain their change order process upfront: how changes are documented, how pricing is determined, and how you authorize them before work proceeds. Vague answers here — or a contractor who says "we'll figure it out as we go" — should give you pause. You want a clear process in writing before the first nail is driven.

→ Ask before signing
07

Evaluate Communication — It Predicts Everything Else

The way a contractor communicates before you hire them is a preview of how they'll communicate during the project. Do they return calls and emails promptly? Do they answer questions directly or give vague, non-committal responses? Do they show up when they say they will for a walkthrough? These behaviors don't change dramatically once a contract is signed — they usually intensify. A contractor who is hard to reach during the sales process will be harder to reach once they have your deposit. Responsiveness and directness before the contract are genuinely predictive of how the project will be managed.

◎ Assess directly
08

Ask for References Relevant to Your Project Type

References matter most when they're specific. A contractor who has done 50 kitchen remodels and wants to pitch you on a new construction build has relevant experience — but the most useful references are from homeowners who did something similar to what you're planning. Ask specifically: "Can you give me a reference from a project similar in scope and budget to mine?" A contractor who has done that kind of work will be able to produce those references readily. And when you call them, ask about communication, how surprises were handled, and whether they'd hire the contractor again — not just whether they were happy with the finished product.

→ Ask for project-matched references
09

Watch the Deposit Request

A reasonable upfront deposit is standard — it covers material procurement and mobilization costs. What's not standard is a contractor asking for 40–50% of the total project cost before work begins. In Washington State, large upfront deposits are a documented warning sign. A reasonable deposit for most residential projects runs 10–15% of the total contract value. If a contractor needs significantly more than that before starting, ask why — and get the answer in writing. Legitimate contractors with healthy businesses don't need to front-load payment to fund their operations.

How to Verify a Contractor in Washington State

Washington State's L&I verification tool is one of the more thorough state contractor databases in the country. Here's exactly how to use it:

🔍 L&I Contractor Verification — Step by Step

01
Go to the official tool: secure.lni.wa.gov/verify — this is the Washington State L&I's free, publicly accessible contractor lookup.
02
Search by business name or contractor registration number. If you have the contractor's registration number, use it — it's more precise than a name search. You can ask any contractor for their registration number directly.
03
Confirm the registration shows "Active." Anything other than Active means they should not be performing contracting work. Also confirm the registration hasn't recently lapsed — Washington registrations renew every two years.
04
Check bond and insurance status. Both should show current, active coverage. Washington requires a minimum 2,000 surety bond and at least 0,000 in general liability insurance for registered contractors.
05
Look at the full record. The tool also shows any safety citations, lawsuits filed against the bond, workers' comp account status, and business owner names. A clean record across all fields is what you're looking for.

"Reviews tell you what past clients thought. The L&I record tells you what the state knows. Both matter — but only one of them is verifiable fact."

Red Flags Worth Walking Away From

Some warning signs are subtle. These aren't. If you encounter any of the following, remove the contractor from your list:

  • 🚩
    Can't or won't provide a registration number. Every licensed contractor in Washington has one. Reluctance to share it means either they don't have one or they don't want you to look it up.
  • 🚩
    Suggests skipping permits. This is never in your interest. It protects them from inspection, not you from bad work.
  • 🚩
    Pressures you to sign or pay quickly. Legitimate contractors don't need to manufacture urgency. High-pressure tactics are a sales technique, not a sign of a full calendar.
  • 🚩
    Provides a verbal estimate only. If they won't put the scope and price in writing before the contract, they won't be accountable to specifics during the project either.
  • 🚩
    A bid dramatically lower than every other quote. As we covered in our handyman vs. GC post — something is missing from that price. It's usually insurance, permits, proper materials, or skilled labor.
  • 🚩
    No fixed address or local presence. A contractor who won't give you a physical business address and who you can only reach by cell phone is harder to hold accountable if problems develop after project completion.
  • 🚩
    Asks you to pull your own permits. Some contractors ask homeowners to take out permits in their own name to avoid the work being tied to their registration. This shifts liability to you and should be a hard stop.

Questions Worth Asking in the Walkthrough

These questions do two things: they give you useful information, and they reveal how the contractor thinks and communicates under mild pressure.

Can you walk me through how you handle something unexpected found behind a wall mid-project?

Who specifically will be on-site day to day, and how do I reach them?

What does your change order process look like — how are they documented and approved?

Can you give me a reference from a project similar in scope and budget to mine?

Which permits will this project require, and who handles pulling them?

What does your craftsmanship warranty cover, and for how long?

💡 On Newer Businesses Specifically

If you're talking to a contractor who is newer to the market — maybe a few years in, with a smaller portfolio and fewer reviews — the questions above are exactly the right framework. A newer business with a clean L&I record, a clear change order process, written scopes, and a direct, knowledgeable person doing the walkthrough is often a better choice than an established business coasting on a large review count and sending a salesperson instead of a contractor to your home.

Newer businesses also tend to have more to prove. That's not a weakness — it's often a source of motivation that shows up in the quality of the work.

The Bottom Line

Hiring a contractor in King County is a significant financial decision, and the Seattle-area market has no shortage of options — which makes the decision harder, not easier. The framework above gives you a way to cut through the noise: start with the verifiable facts, use reviews and portfolios as supplemental context, and invest most of your evaluation energy in the direct interaction — the walkthrough, the written scope, and the references.

The right contractor for your project is the one who can demonstrate their qualifications clearly, communicate directly about scope and process, and give you a written commitment before they ever touch your home. That combination exists in businesses of every size and every age. Don't let review count alone be the thing that determines whether you find them.
