Chimney Repointing

Chimney re-pointing is the process of removing degraded mortar from the joints of a masonry chimney and replacing it with new mortar. If done well, the chimney’s structure will be strengthened and its lifetime extended. If done incorrectly, the chimney’s structure will be compromised and its appearance will be marred.

When a chimney’s mortar is cracking, missing, or deteriorating, chimney re-pointing will need to be done. If neglected, water from the outside will penetrate the chimney’s wall. As the water undergoes freeze-thaw cycles over an extended period, it expands and contracts, leading to the deterioration of the masonry.

Chimney re-pointing will need to be performed as well if the masonry has been re-pointed incorrectly in the past.The mortar in the re-pointed area may not match, it may be too hard, or it may not allow water vapor to escape, which is causing the masonry to crumble, etc.

To ensure that the chimney re-pointing project is properly performed, the mortar joints to be repaired must first be prepared to accept the new mortar. When the appropriate mortar recipe has been selected for the chimney, it must be mixed properly. The process will depend on the recipe. Suction, or the transfer of water from the wet mortar into the masonry, must be controlled as the new mortar is applied. The correct tools and procedures must be observed to ensure the mortar is firmly compacted into the mortar joints. Curing conditions for the mortar like sunlight, temperature, humidity, and wind must be controlled as much as possible after the mortar has been applied. Lastly, the more complicated the project, the more likely a trained and experienced mason will need to be hired.

Chimney re-pointing is critical to maintaining a chimney. Without it, a chimney will degrade and break down before its time.

Chimney Lead Flashing

Roofing damage occurs not only as a result of old, worn shingles but also through chimney flashing damage.

If you wish to install chimney flashing on your asphalt roof for additional security against weathering, request roofing quotes for affordable chimney flashing.

Before you install roof flashing, you should first understand the basic requirements, including compatible materials, appropriate fasteners, separate counter and sub flashing

s, and sealants, in order to ensure a problem-free installation.
