What Homeowners Are Saying
ChimmerJim was at my house within 24 hours. They cleaned the full flue, found a cracked tile I didn't know about, and gave me a clear repair quote. Professional from start to finish.
David M.

Used them for a Level 2 inspection before closing on our home. The report was detailed with photos and the inspector was patient explaining everything. Highly recommend.
Sarah K.
Washington, DC
Fast, clean, and honest. No upsells, no scare tactics — just a thorough sweep and a real inspection. The price matched the quote exactly. Will use every year.
Mike T.
Chicago, IL
My gas fireplace had a pilot light issue. ChimmerJim diagnosed it immediately, replaced the thermocouple, and had it working the same visit. Great service.
Jennifer L.
Austin, TX
Crown was cracked and leaking water into the firebox. They repaired it in one afternoon and applied waterproofing. Two years later, still no leaks.
Robert W.
Boston, MA
I scheduled a dryer vent cleaning after noticing clothes taking forever to dry. After ChimmerJim came out, the difference was immediate. Should have done this years ago.
