Copper caps
Stainless and copper caps resist rust far better than galvanized steel which makes them worth the higher upfront cost.

Chimney Cap Installation Calumet City, IL
Most chimneys in Calumet City should have a cap, and a local sweep can fit one built from stainless steel or copper and sized to the flue or the crown. Dial (708) 708-7203 to talk with a local chimney pro about a cap.
A chimney with no cap lets in water, debris and animals every day of the year. Rain runs straight down the flue, where it rusts dampers, soaks the smoke chamber and mixes with soot to make a sour smell. Birds, squirrels and raccoons see the open top as a safe place to nest.
Caps are made of a lid that keeps precipitation out and wire mesh walls that let smoke and gases pass. The crown seals the top of the brick, while the cap protects the opening of the flue itself.
Not every cap fits every chimney, so sizing and style matter. A single flue cap clamps onto one flue tile, while an outside mount or multi flue cap covers the whole crown and every flue under it. Painted and galvanized steel rust out, while stainless and copper caps hold up for decades.
Chimney Cap Installation is often paired with chimney crown repair and chimney animal removal, depending on the cause.

The chimney cap installation process
Putting on a cap is quick work, but measuring and checking come first.
Clear the flue
Nothing should be trapped below a new cap, so the flue is checked first. If birds are nesting, the timing of the job may change.
Take measurements
The flue tile is measured across the outside and for how far it sticks above the crown. The cap needs enough height above the flue for smoke to escape freely.
Choose the material
You choose between stainless steel and copper and between a single flue or full crown design. Wood, gas and oil flues can each call for a different cap.
Look at the crown
While on the roof, the sweep looks for cracks in the crown and loose flue tiles. Small cracks can be sealed before the cap goes on.
Fasten the cap
The cap is attached firmly so wind and animals cannot pry it loose. A well fastened cap stays put in high wind, and the sweep can tell you how often to check the screen.
What is included
Types of chimney caps
Wildlife screens
Mesh sides keep birds, squirrels, raccoons and bats out of the flue without blocking the draft.
Damper caps
Some caps include a top sealing damper that closes off the flue when the fireplace is not in use for better energy savings.
Multi flue caps
A cap that shades the full crown and all flues together keeps several flues covered under one lid.
Single flue caps
A cap that fits over one flue tile and fastens to it for the typical one flue chimney.

Chimney Cap Replacement Calumet City, IL
Plenty of chimneys already have a cap, but it may be rusted, bent or missing mesh. Torn screens, corroded lids and loose fasteners are the usual reasons a cap needs replacing. Upgrading the material is the main way to avoid replacing the cap again soon.
If you are in Calumet City, a cap that blew off in a storm or one that animals pried loose is worth replacing before the next rain. It helps to tell the sweep whether the chimney has one flue or several and what is vented through it. The sweep can also check whether anything got into the flue while the cap was missing.

Spark Arrestor Installation Calumet City, IL
Spark arrestors are screened caps that trap glowing embers inside the chimney. Mesh that is too fine clogs with soot, and mesh that is too open lets embers through, so the size follows fire safety standards. Local fire rules in dry or wooded areas may require a spark arrestor.
A screen that clogs with soot can push smoke back into the house, so the mesh should be checked during sweeping. Smoke rolling back into the room can be a sign the screen is blocked. A Calumet City sweep can clean the mesh or replace a screen that has rusted through.

Chimneys in this climate
This part of the country gets long winters, heavy snow in places and stretches of bitter cold. Furnaces, wood stoves and fireplaces run hard from fall to spring, which means fast creosote buildup and a lot of stress on liners, crowns and flashing. Snow that piles up behind a chimney and melts slowly is a common source of leaks at the flashing. That is why Calumet City chimney sweeps are busiest every September and October.

Chimney Cap Installation FAQ
How often do chimney caps need to be replaced?
Lifespan depends mostly on the material. Cheaper galvanized steel caps rust out faster, and flue gases from some appliances speed that up. A quick check at each chimney sweeping catches damage early.
Why should I put a cap on my chimney?
The main job of a cap is to keep water and animals out of the chimney. Rusted dampers, damp smells and blocked flues are typical in uncapped chimneys. For the cost of a small part, a cap prevents a lot of trouble.
Can a cap go on if there are birds in the chimney?
If the birds are chimney swifts, federal law protects them, and they have to be left alone until nesting season ends. The sweep will advise on when it is legal to clear the nest. Once the birds have left for the season, the flue can be cleaned and a cap installed to keep them from returning.
What is the difference between a chimney cap and a chimney crown?
A crown is part of the masonry: it seals the top of the brick and slopes water away from the flue. The cap sits on or over the crown and covers only the opening. Each protects a different part, so both should be in good shape.
Will a cap make my fireplace smoke?
The right cap, mounted with enough height above the flue, lets smoke out freely. Trouble usually traces back to a clogged screen or a cap that is undersized or mounted too close to the flue opening. A sweep can clean the mesh or switch to a better fitting cap.
