Why Hiring a Licensed Renovation Contractor Matters in Mercer Island, WA
When hiring a renovation contractor in Mercer Island, licensing is your first line of protection. Washington (WA) requires renovation contractors to hold a valid state license before performing work. This means the contractor has met minimum training, experience, and insurance requirements set by the state. In the Mercer Island area, always ask for the license number upfront — licensed pros carry liability insurance that covers property damage and injuries on the job, they must follow current building codes, and you have legal recourse through the Washington licensing board if work is substandard.
Ask whether they pull their own permits or expect you to. A legitimate renovation contractor handles all permitting. For homes built before 1978, confirm they have EPA RRP lead-safe certification — this is a federal requirement, not optional.
