Stainless and copper caps resist rust far better than galvanized steel so the cap does not need replacing every few years.

Chimney Cap Installation Abington, PA
A chimney sweep in Abington can install a metal cap over your flue with mesh sides that block animals and embers without choking the draft. Call (267) 715-3132 to reach a local chimney sweep.
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. Squirrels, raccoons and birds nest in open flues, and their nests can block smoke from escaping.
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.
Choosing a cap comes down to the shape of the chimney and what it vents. 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.
Depending on what the sweep finds, chimney cap installation in Abington, PA can go hand in hand with chimney crown repair and chimney animal removal.

What happens during a cap installation
Here is how a chimney sweep usually handles a cap installation.
Look inside
Before the cap goes on, the flue is checked for animals, nests and blockages. An occupied flue gets handled before capping.
Take measurements
The sweep measures the length, width and height of the flue tile or crown. The cap needs enough height above the flue for smoke to escape freely.
Choose the material
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
While on the roof, the sweep looks for cracks in the crown and loose flue tiles. Any damage found is pointed out to you.
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
Single flue caps
A cap that fits over one flue tile and fastens to it is the most common type on brick chimneys.
Full crown caps
A cap that shades the full crown and all flues together works when flue tiles are short or uneven.
Top sealing caps
A combined cap and damper closes the flue at the top for a tighter seal than an old throat damper.
Animal guard mesh
A heavy mesh screen blocks animals from nesting in the chimney while letting smoke and gases out.

Chimney Cap Replacement Abington, PA
An old cap can fail in ways that are easy to miss from the ground. Rusted mesh lets animals in, a loose base lets wind tip the cap, and rust streaks down the brick show the metal is breaking down. Swapping to stainless or copper means the new cap should outlast the old one by years.
If you are in Abington, 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. Debris that fell in while the cap was off may need to be cleared out first.

Spark Arrestor Installation Abington, PA
The spark arrestor is the screen around the cap that catches hot embers before they can drift onto the roof or yard. The NFPA 211 standard sets a mesh size that is small enough to stop embers but large enough not to clog quickly, about half an inch or a little less. 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. Smoke rolling back into the room can be a sign the screen is blocked. The fix is usually cleaning the screen or swapping in a new one.

How the weather here affects chimneys around Abington
Winters here are long and cold, and the heating season usually runs from October well into April. Masonry takes the worst of it from the freeze and thaw cycle: rain and melting snow soak into the crown and joints, then freeze and push them apart, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in Abington, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Cap Installation FAQ
Does my chimney really need a cap?
Chimney caps block water, debris and wildlife from getting into the flue while still letting smoke out. Water damage and animal nests are two of the most common chimney problems, and both are largely prevented by a cap. For most homes, a cap is one of the simplest protections a chimney can have.
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. Capping after the birds migrate keeps the next season from repeating.
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. A sweep can clean the mesh or switch to a better fitting cap.
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 is the metal cover with mesh sides that sits over the flue opening above the crown. Having one does not replace the other.
How long does a chimney cap last?
Lifespan depends mostly on the material. Galvanized caps rust much sooner, often within a handful of years. A quick check at each chimney sweeping catches damage early.
