Storm Collar Repair & Installation

A storm collar is a skirt of metal flashing wrapped around your chimney pipe designed to keep rainwater out of your chimney chase. Located just below the chimney cap and just above your chase pan cover, it deflects rainwater as it runs down the outside of your chimney pipe and sheds it onto your chase pan cover.

Although your storm collar is small in size, its job is huge in importance! If your storm collar isn’t doing it’s job, destructive water leaks can cause enough rust damage to your prefabricated chimney and fireplace that the entire system will need to be torn out and replaced anew! A very extensive AND expensive project, indeed!

Here are some telltale signs you can look for to determine whether your storm collar needs attention:

Water Indications

Water Indications

If your prefabricated fireplace has ventilation louvers above your fireplace, shine a flashlight between the louvers and inspect the area where the chimney pipe connects to the top of your firebox. If you see any signs indicating water has been sitting there, your storm collar probably needs attention.

You can also look for signs of water damage inside of your fireplace. Get on your hands and knees and stick your head into your fireplace. Now look upward and locate the fireplace damper (the thing you can open and close to keep warm air from escaping up the chimney). Look at the area surrounding the damper. If you observe water staining or rust, your storm collar is likely in need of repair or replacement. The picture on the far right shows extensive pitting and rust. This kind of damage requires the entire fireplace and chimney pipe be torn out and replaced with an entirely new system.

Most commonly, the bead of caulk sealing the top edge of the storm collar to the chimney pipe fails due to heat and weather exposure. When this bead of caulk fails, it must be resealed with a specialized, high-temperature silicone caulk designed to withstand the extreme temperatures produced while burning fires.

Sometimes, a storm collar is installed too high above the chase pan and it allows rainwater to enter into the chimney chase.

Other times, the storm collar is missing or damaged so badly that it must be replaced altogether.

If your storm collar needs attention, NOW is the time to get it fixed. Procrastinating a small, inexpensive repair such as this will cause big regrets later on!

Testimonials

Dear A to Z,

I just wanted to thank you for your honesty and for a thorough inspection of my chimney. One of the biggest concerns I have when hiring service professionals is being taken advantage when not having first hand knowledge of the various procedures. Last year when I had my chimney swept by one of your competitors, they claimed that I had a chimney fire, and that my flue was now cracked and needed extensive repairs.

This year, I hired A to Z to come out and sweep and inspect the flue because I heard they inspect the chimneys with a Chim Scan camera at no additional charge. The technician who came to my home, assured me I would be able to see any cracks or hazardous conditions along with him as he video scanned my flue. To my utter delight, NO EVIDENCE OF A CHIMNEY FIRE OR DAMAGE IN MY FLUE WAS DETECTED!!! Chris was extremely detailed in his inspection and really took his time educating me so I could feel comfortable. It was obvious that he knew what he was talking about and truly interested in doing the right thing…a far cry from last year’s experience with the other company. If anyone asks for an HONEST, COMPETENT, AND PROFESSIONAL chimney sweep company, I'll be sure to recommend A to Z!

~ Ms. Randi Scott, Lincoln, CA
