HeatShield® Cerfractory Flue Sealant
Gaps between chimney flue tiles and missing mortar joints are potentially very dangerous and should be repaired immediately. It used to be that when gaps between tiles or cracks in the flue tiles were discovered, the only way to repair them was to completely remove the flue tiles and replace them with a stainless steel liner. Unfortunately, there was no way to just reach down inside the chimney and re-pack the missing mortar joints or repair the cracked flue tiles … until now. HeatShield® is the answer to repacking deteriorated mortar joints and resurfacing cracked flue tiles – and it can be done at a fraction of the cost of relining your chimney with stainless steel. If you live in the Sacramento area and have a chimney with cracked flue tiles or eroded mortar joints, do not burn fires until repairs have been performed by one of A to Z Chimney Service’s qualified chimney technicians. We can help you determine if HeatShield® cerfractory sealant is a good solution for your chimney.
Are There Hidden Dangers In Your Chimney?
The combustion process that occurs when you light a fire creates noxious gases that can contain creosote, soot, carbon monoxide, and corrosive chemicals. The purpose of your chimney is to safely vent these hazardous flue gases from your home.
Your chimney’s flue tiles are typically sealed with mortar to keep these gases contained within the flue. However, over time, the mixture of rainwater, heat, and chemicals can erode the mortar between the tiles, leaving potentially dangerous gaps or voids.
Cracks in the flue tiles are potentially hazardous, no matter how small. Even hairline cracks can open wide when the flue tile expands as it is subjected to heat. Flue tiles can crack for numerous reasons, but they do so most often as a result of “sudden occurrences”, such as a previous chimney fire, a lightning strike, or a seismic event. Cracks may also be caused by poor workmanship or the ongoing settling of your home.
If not repaired in a timely manner, these defects can begin a process that will further erode the chimney and create a fire hazard. This is because combustible creosote or soot can escape through gaps and cracks in your liner and build up outside the flue. If the creosote were to catch fire in this area of your chimney, serious damage would occur because the fire would no longer be contained within the flue. The gaps and cracks can also cause health risks by allowing poisonous gases to escape into your home and air supply.

A to Z’s Technician did a terrific job cleaning out my dryer vent! He was very pleasant to work with and professional. He cleaned the outside dryer vent ductwork. It hadn't been cleaned in 10 years so there was a lot of lint and buildup in the ductwork. He said there wasn't much airflow going through the ductwork.
That could explain why it was taking so long for the clothes to dry. It was also a huge fire hazard. He cleaned up the area outside. I couldn't even tell he had been there. He pulled off the bottom of the dryer to check for lint build up in the dryer. There was a lot of lint in there too. He said he could clean the inside of the dryer also for an extra charge of $50.00.
I thought that was a very reasonable price so I had him clean the inside of the dryer also. I am very pleased with his work and glad I finally found someone to clean the vent. His company also automatically makes an appointment to come back in tow years to clean it again. The appointment will be in two years for the same date as the original visit. He put a magnet on the front of the dryer with the future appointment date so I don't forget. I will definitely use his service again.
