We Can Replace Or Install Your Prefabricated Chimney Cap

All prefabricated chimneys need to have a rain cap or spark arrester professionally installed on the very top of the chimney. This is an important part of any prefabricated chimney and fireplace system and should not be allowed to fall into disrepair. Left unchecked over a long period of time, rainwater often takes a toll on chimney caps. It is the most destructive element a prefabricated chimney faces. Since prefabricated fireplaces and chimneys are constructed out of thin sheet metal, rainwater can rust and destroy them in short order. In addition, rainwater infiltration can cause mold, dry rot, and sheet rock damage.

If your prefabricated chimney doesn’t have a chimney cap, or your existing chimney cap is rusted or damaged, now is the time to take care of the most basic preventative chimney maintenance tasks and have one installed. Spending a little money now on a high-quality chimney cap will save you big headaches and expenses later. A to Z Chimney Services stocks the most common sizes and types of prefabricated chimney caps and can have one installed for you quickly.

7 Good Reasons Why You Need A Chimney Cap

A chimney without a cap is like a house without a roof—a recipe for disaster. Here are some of the most compelling reasons for purchasing a chimney cap:

1. Keep destructive rainwater out of your chimney
2. Avoid expensive repairs
3. Keep dangerous sparks from escaping the chimney
4. Keep raccoons, squirrels, opossums, insects, and birds from nesting and creating a fire hazard
5. Prevent rain, leaves, bird droppings, and other debris from getting into the chimney
6. Help prevent smoking problems caused by wind-induced down drafts
7. Satisfy California building code, which requires a 3/8” spark arrester

We Also Carry Chimney Storm Collars

In addition to a chimney cap, prefab chimneys benefit from the installation of a component called a storm collar, which works in concert with the chase cover and cap to create the tightest possible seal against water. A storm collar is a skirt of metal flashing that wraps around your chimney pipe and is located just below your chimney cap and above your chase cover. The collar 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.

If your prefabricated fireplace has ventilation louvers above the firebox, you can determine whether or not your storm collar needs attention by shining a flashlight between the louvers. You may also want to 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.

Angie's List Super Service Award


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.
