"We’re enjoying the heat and beauty of our new fireplace as I write this! Chimney Cricket supported us through a tough series of errors caused by manufacturer’s lack of support. Finally they were able to locate the errors and get our beautiful new fireplace up and running. My only word of warning to folks considering installation of a new fireplace: make sure the model you select has a track record of easy installation and servicing, and that the manufacturer is known for standing behind their products."

"The job was done really well. Everyone was polite, pleasant and responsive to all my questions and concerns. They provided me with before and after photos, which will be put in my "house maintenance" file. They also did the chimney cap but I couldn't pick two options. I highly recommend them."

Customers say: Quality work
"Joe just came out and fixed our fireplace. The pilot light went out years ago, and we were told we'd have to pay over 10k for a new unit, and it'd destroy our mantel. We found Joe on Angi and set up an appointment within a week. He came out this afternoon, and within an hour our decades-old fireplace was up and running! He cleaned everything, and now it works better than ever. We are so grateful, and excited to have our fireplace for the winter! We definitely recommend Joe O'Neill of O'Neill's Gas Services."

Start with a professional inspection. If damage is limited to a few bricks or the crown, a targeted repair helps keep costs and disruption to a minimum. Severe leaning, widespread mortar failure, or major fire damage usually signals it’s time for a complete teardown and rebuild. Your contractor will outline both price tags, but remember that rebuilding a failing stack is often cheaper than repeated patch jobs and the water leaks or fire hazards they allow.
Cracks provide water with an easy path into the masonry, weakening the bricks and mortar and increasing the risk of collapse or fire. Gaps can also let hot gases and sparks escape into attic spaces. Call a chimney pro as soon as you see cracking so they can seal small joints or recommend a larger rebuild before minor damage turns into a costly emergency.
Smoke rolling back into the room often indicates a blocked flue, a broken damper, or a drafting issue. Have a sweep inspect the damper, flue liner, and any obstructions right away. Most fixes involve clearing debris, repairing the liner, or adjusting the damper so the fireplace pulls air correctly. Don’t light another fire until a professional pinpoints the cause and confirms your system is venting safely.
Most policies cover chimney repairs caused by a sudden, covered event, such as lightning, a fallen tree, or a house fire. They won’t cover damage that stems from neglected maintenance or everyday wear. Review your policy or contact your agent before scheduling work to determine what documentation your insurer requires and what costs you will be responsible for.
Component life spans vary. Clay tile or cast-in-place liners last close to 50 years, while stainless-steel liners last 15 to 20 years. Mortar requires attention every 25 to 30 years, while crowns last 50 to 75 years. Use these numbers as a maintenance roadmap: schedule regular inspections, budget for future upgrades, and replace parts before age-related cracks develop into more significant problems.
