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.

Your employee was on time and very careful about cleanliness! I appreciated the fact that he took the time to not only put tarps down in front of my fireplace, but also everywhere he walked as he came in and out of my home… I have had my chimney cleaned by several companies over the years, and I don’t think I remember anybody being as careful to keep it clean as A to Z!
Also, another difference I noticed was the fact that your guy was here about ½ hour longer than any other chimney guys I’ve had in the past. Not only did it seem he was more meticulous and concerned about doing a thorough job, but he also put a Chim Scan Camera up into my chimney after cleaning to make sure there were no dangerous cracks or gaps.
You guys weren’t the cheapest in town, but I feel I DEFINTELY got a better value with your company than any others I’ve used in the past. You took more time, did a better job, and thoroughly answered all of my questions in terms that I could understand.
Great job from start to finish! Now that I’ve found you, I’ll use A to Z exclusively from now on!
