Chimney Damper Installation

Your chimney’s damper blocks off the flue when it’s not in use, which serves two functions: it keeps rain, snow and other elements out and it keeps the heated or cooled air in your home from escaping.

A chimney damper can get stuck in place due to debris or corrosion. If you’re experiencing issues with your damper, an experienced A-1 Chimney Specialist technician can assess whether it can be repaired (usually by adjusting and/or lubricating the moving parts), or whether you’ll need to replace the damper.

Types Of Chimney Dampers

Throat Dampers

Most fireplaces were installed with throat dampers, which are located at the top of the firebox, blocking off the flue there when closed. Throat dampers are generally controlled either by a knob above the fireplace or with a handle inside the firebox.

When a chimney is properly maintained and routinely swept, these can be good and functional dampers. But they can break, get stuck or come off the track they sit on. If your damaged throat damper is still in reparable condition, an A-1 Chimney Specialist technician will be glad to help restore it. If your throat damper gets damaged beyond repair, a top-end damper can be a beneficial replacement, and we can install one that works with your system.

Top-End Dampers

A top-end damper is installed at the very top of your flue and is usually controlled by either a chain that runs through the flue or a handle at the side of the firebox.

These dampers can bring several benefits, first and foremost being energy savings. Top-end dampers are highly efficient, with a gasket that forms a tight seal over the flue, effectively closing your chimney off from the elements. This means you’re not paying to heat the cool air in your chimney during the winter, or cool the hot air during the summer.

Many homeowners are choosing to replace their throat dampers with top-end dampers to take advantage of this energy efficiency boost.

Is Your Chimney Leaking? Faulty Dampers Can Sometimes Be The Culprit

Chimney leaks are frustrating and complicated, but there are several places that we commonly find leaks originating from, including the: chimney cap, chimney crown, chimney flashing and the chimney damper.

If your chimney is leaking, have an A-1 Chimney Specialist technician take a look. We’ll check your damper during a thorough inspection and repair or replace it if it isn’t functioning correctly.

  • review rating 5  Great service! Due to unexpected doctor appointments, I had to reschedule two times and they worked with me to get it done as soon as possible. They were very prompt; the living area was left exactly as it was when they arrived (no mess at all!) and answered my questions. I highly recommend them!

  • review rating 5  In a time where customer service is becoming more infrequent than frequent , I have to take a moment to acknowledge the superb above and beyond service my husband and I received from A1 Chimney . First of all , we came to use this company several years ago when they sleeved our 100 year old house's chimney so we could burn real wood . We have used them regularly to check and sweep our chimney since. This year however , I had a chimney fire . Thankfully no damage was done . In looking at my records , I realized I hadn't had the chimney swept in a few years . BIG mistake on my part , hence the fire . So I called the company , sing my woes , asking if it would be possible for them to come out before Thanksgiving , this is less than 2 weeks prior by the way . Kind Marty lets me know the first availability isn't until 12/16 but he will do his best to see what he can do. He calls me back the same day to let me know he had jiggled some things around and could be out 12/13 . I thanked him but asked if there were any cancellations to please let me know. Kind Marty , let me rephrase , very KIND Marty , calls me back a couple of days ago asking if we could be free the Monday pre Thanksgiving . Absolutely , I reply . Well on Monday afternoon Preston and Robert leave after checking for damage , cleaning and confirming the sleeve did exactly what it is designed to do , protect the house in the event a chimney fire takes place , never once suggesting it wouldn't have happened if I hadn't waited 4 years . So THANK YOU all for doing such a wonderful job ! You have made us and my out of town family very happy in making it safe for us to enjoy this holiday with lovely fires , something we / they look forward to on their cold weather visits . May each of you have a very Happy Thanksgiving ! You've certainly made ours !!! Gratefully , Linda & Gill Ramsden
