Prefabricated Chimney Firestop Installation
Deep within the bowels of your prefabricated chimney’s chase is something called a “Firestop”. Do you have any guesses as to what it does? I’ll give you a hint….. who’s buried in Grant’s tomb?
Just as its name implies, a firestop stops fires…well, sort of…it actually just slows them down.
A firestop is a horizontal fire-blockade constructed of non-combustible materials (usually sheet metal or gypsum board) and/or plywood of a minimum thickness. It’s job is to make sure that if a fire starts somewhere within your hollow wooden framed chimney chase, it’s spread will be slowed down as much as possible until your friendly fire department can get there to put it out.
In the absence of a firestop, a fire inside of your chimney chase would likely spread so rapidly that fire crews couldn’t respond quick enough to save your home, or worse yet, before you and your family were able to escape safely.
Building code requires that a firestop be installed anywhere the chimney passes through a ceiling or floor, and the material directly surrounding your chimney pipe be constructed of galvanized sheet metal not less than 26 gauge.
If it is discovered that your chimney has a missing or damaged firestop, A to Z recommends you not burn fires until you hire a professional to bring it up to code as soon as possible.
Keeping the flashing in good repair is one of the best and simplest ways you can guard against unwanted water leaks. If your prefab chimney needs this repair, call on A to Z for dependable, quality work.

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.
