Chimney Cap Installation Winfield, IL
A chimney sweep in Winfield can install a metal cap over your flue built from stainless steel or copper and sized to the flue or the crown. Dial (331) 716-1355 to talk with a local chimney pro about a cap.
Without a cap, the top of a flue is open to rain, snow, leaves and wildlife. Every storm sends water down the flue, and over time that means rusted dampers, wet masonry and a musty fireplace. Animals treat an uncapped chimney like a hollow tree.
The cap itself is a simple part: a solid top to shed water, mesh sides to block animals and a base that fastens to the chimney. It is not the same thing as the crown, which is the concrete or mortar slab that covers the top of the masonry.
Choosing a cap comes down to the shape of the chimney and what it vents. 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. Stainless steel and copper last far longer than galvanized or painted steel, which rusts and streaks the masonry within a few years.
If the problem goes deeper than it first looked, a Winfield chimney sweep may also recommend chimney crown repair or chimney animal removal.

Call nowThe process
The chimney cap installation process
A cap that fits well and is fastened properly will stay on through years of wind.
Check the flue first
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.
Size the cap
The sweep measures the length, width and height of the flue tile or crown. Getting the size right keeps the cap secure and the draft strong.
Choose the material
You choose between stainless steel and copper and between a single flue or full crown design. The appliance using the flue affects the choice.
Inspect the top
A cap needs a solid base, so the crown and tile are inspected. Crown repairs are easier to handle at the same time.
Install the cap
A single flue cap is tightened onto the tile, and crown mount caps are fastened into the masonry. 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
Full crown caps
A cap that shades the full crown and all flues together also protects the crown from direct rain.
Wildlife screens
A heavy mesh screen blocks animals from nesting in the chimney while letting smoke and gases out.
Stainless steel caps
Stainless and copper caps resist rust far better than galvanized steel so the cap does not need replacing every few years.
Single flue caps
A simple cap for one flue extending above the crown for the typical one flue chimney.

Chimney Cap Replacement Winfield, IL
Caps do not last forever, especially the galvanized ones that come on many homes. 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.
If you are in Winfield, a cap that blew off in a storm or one that animals pried loose is worth replacing before the next rain. When you call (331) 716-1355, 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 Winfield, IL
The spark arrestor is the screen around the cap that catches hot embers before they can drift onto the roof or yard. Fire standards like NFPA 211 call for mesh openings of roughly three eighths to one half inch, which balances ember control with airflow. Some communities with wildfire risk require them on every wood burning chimney.
Spark arrestor mesh needs occasional cleaning, because creosote and soot can build up on the screen and slow the draft. Smoke rolling back into the room can be a sign the screen is blocked. Cleaning or replacing the mesh restores the draft.

Chimneys in this climate
Winters here are cold and long, with lake effect snow in many towns and deep cold snaps that can last for days. Heating systems and wood stoves work nearly nonstop for months, which means fast creosote buildup and a lot of stress on liners, crowns and flashing. Snow drifting against the back of a chimney melts slowly and works water under tired flashing. That is why Winfield chimney sweeps are busiest every September and October.

Chimney Cap Installation FAQ
Is a chimney crown the same as a cap?
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. Each protects a different part, so both should be in good shape.
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 sweep can tell you what kind of bird it is and advise on timing. After they leave, the nest is removed and a cap goes on.
What does a chimney cap actually do?
Chimney caps block water, debris and wildlife from getting into the flue while still letting smoke out. Water in the flue causes rust, crumbling mortar and odors, and animals can block the flue completely. For most homes, a cap is one of the simplest protections a chimney can have.
How long does a chimney cap last?
Stainless steel and copper caps often last for decades with little upkeep. Galvanized and painted steel caps tend to rust within several years, especially near the coast or with oil fired appliances. Have the cap looked at during each sweeping, since wind and wildlife can loosen it.
Will a cap make my fireplace smoke?
Well fitted caps rarely cause draft trouble. When a cap does cause smoke issues, the mesh is usually caked with soot or the cap is the wrong size. A sweep can clean the mesh or switch to a better fitting cap.
