Chimney Cap Installation Northbrook, IL
Most chimneys in Northbrook should have a cap, and a local sweep can fit one that keeps rain, birds, raccoons and leaves out while letting smoke escape. Call (224) 458-2675 to reach a local chimney sweep.
An uncapped chimney is an open hole in the roof, and plenty of things find their way into it. Rain runs straight down the flue, where it rusts dampers, soaks the smoke chamber and mixes with soot to make a sour smell. Animals treat an uncapped chimney like a hollow tree.
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.
The right cap depends on the chimney. Some caps fasten to the flue tile with screws or a clamp, and others mount to the crown and cover all the flues at once. Painted and galvanized steel rust out, while stainless and copper caps hold up for decades.
Depending on what the sweep finds, chimney cap installation in Northbrook, IL can go hand in hand with chimney crown repair and chimney animal removal.

The chimney cap installation process
Here is how a chimney sweep usually handles a cap installation.
Clear the flue
The sweep checks that the flue is clear of nests and debris before closing it in. If birds are nesting, the timing of the job may change.
Measure the flue
The flue tile is measured across the outside and for how far it sticks above the crown. Getting the size right keeps the cap secure and the draft strong.
Pick the right cap
The cap is matched to the chimney, the appliance and the look of the house. Gas appliance flues may need caps listed for that use.
Look at the crown
The crown and the top of the flue are checked so the cap is not mounted on failing masonry. Small cracks can be sealed before the cap goes on.
Install the cap
A single flue cap is tightened onto the tile, and crown mount caps are fastened into the masonry. It should not wobble when pushed, and you will hear when the mesh should be checked for soot.
What is included
What chimney cap installation covers
Top sealing caps
Some caps include a top sealing damper that closes off the flue when the fireplace is not in use for a tighter seal than an old throat damper.
Flue tile caps
Caps made for a single flue that clamp or screw onto the tile is the most common type on brick chimneys.
Animal guard mesh
Screened sides stop wildlife from getting in while letting smoke and gases out.
Copper caps
Stainless steel holds up to weather and flue gases for many years so the cap does not need replacing every few years.

Plenty of chimneys already have a cap, but it may be rusted, bent or missing mesh. 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.
In Northbrook, a missing cap is often noticed only after a nest or a wet firebox appears. Calling (224) 458-2675 with a few details, such as how many flues there are and what fuel you burn, helps the sweep plan the job. Debris that fell in while the cap was off may need to be cleared out first.

Spark Arrestor Installation Northbrook, 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. Fire standards like NFPA 211 call for mesh openings of roughly three eighths to one half inch, which balances ember control with airflow. Check with your local fire department, since some areas require arrestors on wood burning chimneys.
A screen that clogs with soot can push smoke back into the house, so the mesh should be checked during sweeping. A smoky fireplace after years of good draft can point to a clogged screen. The fix is usually cleaning the screen or swapping in a new one.

How the weather here affects chimneys around Northbrook
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 that piles up behind a chimney and melts slowly is a common source of leaks at the flashing. That is why Northbrook chimney sweeps are busiest every September and October.

Common questions about chimney cap installation
Does my chimney really need a cap?
A cap keeps rain, snow, leaves and animals out of the flue, which protects the damper, the masonry and the inside of the chimney. Rusted dampers, damp smells and blocked flues are typical in uncapped chimneys. Most chimney sweeps recommend a cap on every flue.
What should I do if birds are nesting in my chimney?
Some chimney birds, especially chimney swifts, are protected, which limits what can be done during nesting season. 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?
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. A chimney needs both, and a cracked crown can leak even with a good cap.
Can a chimney cap cause draft problems?
Well fitted caps rarely cause draft trouble. 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.
How long does a chimney cap last?
Lifespan depends mostly on the material. Cheaper galvanized steel caps rust out faster, and flue gases from some appliances speed that up. Storms and animals can damage any cap, so it is worth having it checked when the chimney is swept.
