The idea behind tuck-pointing is that damaged mortar is removed, and it is replaced with fresh mortar. Tuck-pointing a red brick chimney involves the following basic steps:
- Grounding or routing out the old mortar at a uniform depth.
- Filling in red mortar in the newly routed grooves.
- Cutting thin strips down the middle of the red mortar, to form grooves.
- Filling in the grooves with mortar color which matches the original mortar on the outside of the structure.
Tuck-pointing is really a crucial procedure, to preserve the life of a chimney. It can help stop or prevent:
- Corrosion of the mortar joints.
- Structural stability of the chimney is restored.
- It helps prevent water from entering into the chimney system. If the mortar joints are not repaired, water will seep down the chimney and sometimes between the chimney and flue lining.
- It is far more cost-effective than a complete tear down and rebuild.
- Masonry materials are restored to their original condition
- Value of your home is improved when the masonry is in top condition
Crown seal is applied to seal the cap and provide a water proof barrier. The top of a masonry chimney has a concrete “cap” called a crown. Over time, the concrete cracks and eventually begins to deteriorate. This can lead to water seeping into the chimney. The crown coat is best suited for minor cracks and minimal deterioration.
Crown repair can also be done and this needed when the existing crown has deteriorated beyond repair, a new crown will need to be poured.
A stainless steel chimney liner can make your home safer for a relatively small investment. If you have an unlined chimney or a clay tile liner that is many decades old, it is likely that you have cracked tiles or missing mortar. This can be letting noxious gases and smoke into your attic or living areas.
A stainless steel chimney liner will protect your chimney from corrosive combustion products. The liner is sealed from top to bottom so that the smoke, creosote, water and carbon dioxide from burning fuel are carried outside without contacting the masonry chimney structure. Stainless steel is corrosion resistant, so a stainless steel liner will last many years.
A stainless steel chimney liner is easier to clean, and therefore less expensive to maintain, than unlined or clay tile lined flue. It is easier to clean the round steel liner than it is to clean the square or tightly rounded corners inside an unlined or tile lined flue.
Most high efficiency fuel burning appliances require stainless steel liners.
A stainless steel liner may improve your home’s energy efficiency. As mentioned above, an insulated liner reduces cold down drafts when you are not burning a fire. It also improves chimney draft since hotter gases will draw better than colder gases. Good draft improves fuel efficiency through more complete combustion.
A stainless steel liner is easier to install than other types of liners. Adding or replacing a clay tile liner inside a masonry chimney is more labor intensive and usually more expensive than inserting a S/S liner inside the flue.
