I had to have my kitchen drain repaired, which required cutting into the wall. Mark came in afterward to repair the damage, and he did an excellent job. He was professional, friendly, and stayed exactly on budget. I highly recommend him and will definitely use his services again in the future.…

Full Verification Guide

Protect your home improvement project

Surety bond protection

Oregon's surety bond covers incomplete or defective work up to the bond limit. File a claim with the Oregon CCB within 2 years of project completion. How to file a bond claim →

General liability insurance

General liability covers property damage and bodily injury during the project. Ask for a COI (Certificate of Insurance) listing your address as an additional insured location.

Written contract required

Oregon law requires a written contract for residential projects over $2,000. It must include the CCB number, scope of work, and payment schedule. Contract requirements →

Workers' compensation coverage

Contractors with employees in Oregon are required to carry workers' compensation insurance. If a worker is injured on your property without coverage, you may bear liability. Verify coverage status before work begins.

Homeowners typically compare multiple licensed contractors before starting a project.

Before you hire

Verify this contractor carries active general liability insurance and a current surety bond. Request a Certificate of Insurance (COI) listing your property before any work begins. Oregon contractors must maintain minimum coverage - an Active license does not guarantee current insurance.

Compare contractor quotes

Before hiring, get 2–3 written estimates from licensed Oregon contractors. Compare Residential General Contractorss in Portland to ensure competitive pricing.
