M&K Insulation Specialists LLC

Washington requires specialty contractors to file a $15,000 surety bond with the Department of Labor & Industries as a condition of registration ($30,000 for general contractors).

The bond is a limited fund a homeowner (or subcontractor or supplier) can make a claim against, through the courts, if a registered contractor fails to meet its obligations on a job. Contractors must also keep general liability insurance on file — at least $50,000 in property damage and $200,000 in public liability coverage, or a $250,000 combined single limit — which covers damage the contractor causes, not workmanship disputes. The rows above are the bond and insurance filings L&I publishes for this registration; whether a specific filing applies to a specific project depends on its dates and terms.

Insulation contractors install thermal and acoustical insulation — batts, blown-in, rigid foam, and spray products — in attics, walls, floors, and ceilings. Jobs commonly include air sealing, sound-dampening treatments, and adding insulation to older homes. The registration requires a $15,000 surety bond and general liability insurance on file with WA L&I.
