Calculating Chimney Rebuild Costs
A chimney rebuild can be more cost-effective than attempting to repair an existing chimney that is damaged or cracked. The following considerations will help you establish the costs of a chimney rebuild.
One of the major determining factors in the cost to rebuild a chimney is its size. If you have access to your home building plans, they should include chimney dimensions details. If you do not have access to this information, you will need to take measurements by climbing up and measuring the chimney from the roof. Start at the roofline and go to the top of the chimney. Next you will need to measure the width of each side. If the chimney has more than one thickness—if it's wider at the bottom and narrower at the top, for instance—measure each area. Multiply height by width by depth to determine the square inch measurement for the chimney.
Regular standard bricks are not terribly expensive. However, if you are taking the opportunity to update your chimney wth natural stone or other materials, the cost for your chimney will be higher.
Cost per Square Inch
The average cost per square inch for a chimney rebuild ranges from $100 to $200, depending on regional costs for labor and materials. If you are rebuilding the chimney yourself, the labor costs will be considerably lower.
