Chimney repair costs $200 to $700 to fix minor cracks, flashing, fill small joints, or patch up the cap. Bigger repairs cost $1,000 to $3,500 on average to replace the crown, resurface the chimney, or rebuilding a leaning chimney above the roof.
Homeowners insurance does not typically cover general chimney repairs that result from normal fireplace usage over time. However, your insurance can cover repairs if the damage occurs from an unexpected lightning strike, chimney fire, tornado, or other natural disaster.
Chimney repairers don't expect you to tip them for a routine inspection and cleaning. You can tip $20 to $60 extra if the technicians exceeded expectations on an unexpectedly difficult repair job.
The homeowners are typically responsible for chimney repair, but the landlord is responsible for chimney maintenance and routine inspections. Consult your homeowners association and rental agreements for the specific laws in your state.
Chimney repair doesn't require a permit if the work is part of a minor cleaning or routine inspection. However, a permit is necessary when chimney demolition or extensive masonry work is necessary.
You should repair your chimney if the damage isn't structural and costs are less than $600 to $1,000 for a partial rebuild. If the damage is structural, extensive, and spreading, then you should rebuild the chimney. A chimney rebuild costs $1,000 to $3,500 above the roofline only or $4,000 to $15,000 for a full replacement.
Depending on the extent of the chimney problems, your repair project can include:
A cracked chimney is dangerous because it lets heat, moisture, and poisonous carbon monoxide gases escape into the home. Untreated cracks result in structural damages and higher fire risks. Moisture from the cracks also leads to wood rot around the fireplace and mold growth.
A chimney sweep or mason repairs chimneys, unlike roofers who only have training for fixing general roof surfaces. Before hiring a chimney technician, use this checklist:
Search, get cost estimates, contact pros, and book—all for free.
View profiles, read reviews, check qualifications, and see prices before hiring.
Ask questions, confirm their availability, and hire the right pro when you're ready.
