What to Look for in a Chicago Chimney Sweep
The most important credential is NCSG certification (National Chimney Sweep Guild). NCSG-certified technicians have passed written exams and demonstrate working knowledge of chimney systems, safety standards, and NFPA codes. Also verify the company is licensed and carries liability insurance in Illinois.
Red Flags to Avoid
Be cautious of companies that offer unusually low prices and then find urgent repairs on every job, will not give you a written estimate before starting, cannot show proof of NCSG certification or insurance, or pressure you into same-day decisions. Honest chimney companies provide photo-documented inspection reports.
Questions to Ask Before Booking
Ask: Are your technicians NCSG certified? Are you licensed and insured in Illinois? Do you provide a written estimate before starting work? Do you take photos during the inspection? What does the cleaning include? A reputable company will answer all of these without hesitation.
