Prefabricated Chimney Chase Pan Replacement

A Chase Pan is like a shallow cookie pan installed upside down over the top of your chimney. It’s sole purpose is to keep damaging rain water from entering the chimney structure and your home. Sometimes a Chase Pan Covers allows water to leak into the chimney because it’s made or installed improperly, or it has developed rust which has eaten a hole clear through the metal due to standing water ponding for long periods of time.

If this is the case with your Chase Pan Cover, it should be replaced before continued water intrusion is allowed to further damage your fireplace, walls, or chimney chase. We have seen many cases where a neglected water leak has caused the fireplace to become rusted through, wood siding and 2×4’s become dry rotted, and walls and ceilings need to be replaced. Paying a little now to have a new, properly-fitted chase pan cover installed will save lots of money and headaches in the long run.

Angie's List Super Service Award


This was my first experience having my chimney cleaned and I wasn’t sure quite what to expect! I was very impressed with how careful the technician was to ensure that nothing got on our carpet or couches using tarps and a special vacuum to filter the air and ensure no soot got into the home.

It was a good feeling when your technician started setting up and took the time to assure me he would leave my home as clean as he found it.

A to Z is definitely pro! Thanks for a professionally clean chimney, and a totally clean house!
