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

Chimney Cap Installation Sharon, PA
A Sharon chimney sweep can measure your flue and install a chimney cap with mesh sides that block animals and embers without choking the draft. Dial (724) 509-7140 to talk with a local chimney pro about a cap.
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. Squirrels, raccoons and birds nest in open flues, and their nests can block smoke from escaping.
Caps are made of a lid that keeps precipitation out and wire mesh walls that let smoke and gases pass. People often confuse the cap with the crown, but the crown is the masonry slab and the cap is the metal piece above the flue.
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. Galvanized caps cost less up front but tend to rust, so stainless steel or copper is the longer lasting choice.
Many chimney cap installation calls in Sharon also turn up a need for chimney crown repair or chimney animal removal.

How chimney cap installation works
Here is how a chimney sweep usually handles a cap installation.
Look inside
The sweep checks that the flue is clear of nests and debris before closing it in. Active nests can affect when the cap goes on.
Measure the flue
The sweep measures the length, width and height of the flue tile or crown. A cap that is too small will not fit, and one that sits too low can restrict draft.
Select a style
Material and style are settled, along with mesh size and any extras like a wind band. Gas appliance flues may need caps listed for that use.
Check the crown
While on the roof, the sweep looks for cracks in the crown and loose flue tiles. Crown repairs are easier to handle at the same time.
Fasten the cap
The cap is screwed or clamped to the flue tile, or anchored to the crown for outside mount models. Raccoons can pull off a loose cap, so it is set tight and checked before the sweep leaves the roof.
What is included
What chimney cap installation covers
Flue tile caps
A cap that fits over one flue tile and fastens to it for the typical one flue chimney.
Top sealing caps
A combined cap and damper closes the flue at the top which helps where the throat damper is worn out.
Wildlife screens
A heavy mesh screen blocks animals from nesting in the chimney while letting smoke and gases out.
Full crown caps
Outside mount caps that span the whole top of the chimney works when flue tiles are short or uneven.

Chimney Cap Replacement Sharon, PA
Plenty of chimneys already have a cap, but it may be rusted, bent or missing mesh. 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. Upgrading the material is the main way to avoid replacing the cap again soon.
Homeowners in Sharon often find out about a failed cap when water or an animal shows up in the fireplace. When you call (724) 509-7140, 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 Sharon, 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. 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. If smoke suddenly starts spilling into the room, a clogged screen is one of the first things to check. The fix is usually cleaning the screen or swapping in a new one.

Chimney Cap Installation Near Me

How the weather here affects chimneys around Sharon
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. That is why chimney cleaning in Sharon is usually booked in the fall, before the first cold night.

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. Rusted dampers, damp smells and blocked flues are typical in uncapped chimneys. For most homes, a cap is one of the simplest protections a chimney can have.
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. Once the birds have left for the season, the flue can be cleaned and a cap installed to keep them from returning.
How long does a chimney cap last?
Lifespan depends mostly on the material. Galvanized caps rust much sooner, often within a handful of years. Storms and animals can damage any cap, so it is worth having it checked when the chimney is swept.
Is a chimney crown the same as a cap?
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. A chimney needs both, and a cracked crown can leak even with a good cap.
Can a chimney cap cause draft problems?
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.
