The cost to replace a chimney is about $10,000 on average and can cost up to $15,000, depending on the size, accessibility, materials, and extent of the replacement. Sometimes tearing the chimney down to the roof line and rebuilding it is an option. But if the chimney's internal structure deteriorates badly enough, a complete demolition down to the fireplace or the foundation may be necessary.
The cost to replace the chimney crown or top is about $1,550 on average. The range varies widely depending on the size of the chimney, the materials used, accessibility, and the extent of the damage. If you suspect a problem with your chimney top, call a professional masonry contractor for an inspection.
Call a masonry contractor for chimney repairs. Ask the masons you contact if they have experience with chimney repairs, as some masons specialize in them or have extensive experience working on brick or stone chimneys.
Contact a chimney sweep to clean your chimney at least once a year to prevent creosote buildup that can cause fires. Chimney repair is not a recommended DIY job because of the potentially hazardous work on a roof and the stakes for ensuring the chimney repairs are done properly to avoid leakage and fires.
