1. Cracked, Chipped, or Missing Bricks Repair<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Broken or cracked bricks are most commonly a result of water entry combined with freeze-thaw action. Water seeps into the bricks, and freezing causes the water to expand, which leads to breaking off of the bricks. General wear and tear can also lead to this situation.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Level of Repair<\/th>Cost Estimate<\/th>What is covered under this repair<\/th>How It Should Be Prevented<\/th><\/tr>
Easy to Moderate<\/td>Usually, it costs from $200 to $800, which may vary based upon the number of damaged bricks and the height of the chimney.<\/td>The broken bricks need to be cut out delicately without damaging the adjacent bricks. New bricks of the same color and shape as the originals are reinstalled with new mortar applied. It is important that the mortar mix be the same as before for both appearance and strength of bonding.<\/td>To avoid damage to the bricks, waterproof sealants need to be applied onto the chimney surface every few years. Regular inspections\u2014particularly before and after winter\u2014also serve to detect minute cracks early before they propagate.<\/td><\/tr><\/tbody><\/table>

2. Repointing or Tuckpointing (Deteriorated Mortar Joints)<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Mortar joints deteriorate over the course of time because of exposure to rain, snow, and weather changes. Acid rain or incorrect mixtures of mortar at the time of original construction also lead to quicker decay. Water leakage makes the condition worse, as water tends to make the mortar disintegrate.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t
Level of Repair<\/th>Cost Estimate<\/th>What is covered under this repair<\/th>How It Should Be Prevented<\/th><\/tr>
Easy to Moderate<\/td>Usually between $500 and $2,500 depending on chimney height, accessibility, total surface area.<\/td>The weakened old mortar is removed to a specified depth (typically \u00be inch), and new mortar is installed and toiled to its original finish. Tuckpointing improves the look of the chimney in addition to improving the structural strength of the chimney.<\/td>Use a superior mortar mix that is compatible with the original while building or repairing. Seal the chimney from water intrusion, and maintain regular inspections to detect loose or deteriorating mortar prematurely.<\/td><\/tr><\/tbody><\/table>

The crown of the chimney is a concrete slab on top of the chimney, intended to prevent rain and snow from entering the flue.
