Stainless steel caps
Stainless steel holds up to weather and flue gases for many years so the cap does not need replacing every few years.

Chimney Cap Installation Millstadt, IL
A chimney sweep in Millstadt can install a metal cap over your flue that keeps rain, birds, raccoons and leaves out while letting smoke escape. One call to (618) 476-0260 reaches a nearby sweep who installs caps.
A chimney with no cap lets in water, debris and animals every day of the year. Every storm sends water down the flue, and over time that means rusted dampers, wet masonry and a musty fireplace. Birds, squirrels and raccoons see the open top as a safe place to nest.
A chimney cap is a metal hood with mesh sides that sits over the flue opening. It is not the same thing as the crown, which is the concrete or mortar slab that covers the top of the masonry.
Not every cap fits every chimney, so sizing and style matter. One flue sticking up from the crown takes a single flue cap, and several flues or a short tile usually call for a full crown cap. Galvanized caps cost less up front but tend to rust, so stainless steel or copper is the longer lasting choice.
Chimney Cap Installation is often paired with chimney crown repair and chimney animal removal, depending on the cause.

What happens during a cap installation
Here is how a chimney sweep usually handles a cap installation.
Clear the flue
Before the cap goes on, the flue is checked for animals, nests and blockages. An occupied flue gets handled before capping.
Size the cap
Measurements of the flue tile, or of the whole crown, decide which cap fits. A cap that is too small will not fit, and one that sits too low can restrict draft.
Pick the right cap
Material and style are settled, along with mesh size and any extras like a wind band. Wood, gas and oil flues can each call for a different cap.
Look at the crown
The crown and the top of the flue are checked so the cap is not mounted on failing masonry. Crown repairs are easier to handle at the same time.
Install the cap
The cap is attached firmly so wind and animals cannot pry it loose. It should not wobble when pushed, and you will hear when the mesh should be checked for soot.
What is included
Types of chimney caps
Full crown caps
A larger cap that covers the entire crown and every flue under it keeps several flues covered under one lid.
Single flue caps
A simple cap for one flue extending above the crown and keeps the crown visible.
Top sealing caps
Caps with a built in damper seal the top of the flue and cut drafts for a tighter seal than an old throat damper.
Animal guard mesh
Screened sides stop wildlife from getting in without blocking the draft.

Chimney Cap Replacement Millstadt, IL
An old cap can fail in ways that are easy to miss from the ground. Look for rust stains on the crown, a tilted lid or gaps in the screen. Upgrading the material is the main way to avoid replacing the cap again soon.
Homeowners in Millstadt often find out about a failed cap when water or an animal shows up in the fireplace. When you call (618) 476-0260, mention whether the old cap is still on the chimney and what the fireplace or stove burns. Debris that fell in while the cap was off may need to be cleared out first.

Spark Arrestor Installation Millstadt, IL
A spark arrestor is the mesh screen on a chimney cap that stops burning embers from leaving the flue and landing on the roof or nearby trees. 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.
Over time, soot collects on the screen, which is why sweeps check the mesh whenever the flue is cleaned. Smoke rolling back into the room can be a sign the screen is blocked. Cleaning or replacing the mesh restores the draft.

What the local climate does to a chimney
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, so flues collect creosote fast and liners and crowns see a lot of heat and cold. Snow drifting against the back of a chimney melts slowly and works water under tired flashing. That is why Millstadt chimney sweeps are busiest every September and October.

Chimney Cap Installation questions
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. A chimney sweep can identify the bird and tell you when the flue can be cleared. Capping after the birds migrate keeps the next season from repeating.
How long does a chimney cap last?
Stainless steel and copper caps often last for decades with little upkeep. Cheaper galvanized steel caps rust out faster, and flue gases from some appliances speed that up. Have the cap looked at during each sweeping, since wind and wildlife can loosen it.
Why should I put a cap on my chimney?
A cap keeps rain, snow, leaves and animals out of the flue, which protects the damper, the masonry and the inside of the chimney. Water damage and animal nests are two of the most common chimney problems, and both are largely prevented by a cap. For the cost of a small part, a cap prevents a lot of trouble.
Can a chimney cap cause draft problems?
The right cap, mounted with enough height above the flue, lets smoke out freely. When a cap does cause smoke issues, the mesh is usually caked with soot or the cap is the wrong size. Cleaning or resizing the cap usually fixes it.
What is the difference between a chimney cap and a chimney crown?
The crown is the slab of concrete or mortar that covers the top of the masonry around the flue. The cap sits on or over the crown and covers only the opening. Having one does not replace the other.
