Chimney Cap Installation Somerdale, NJ
A Somerdale chimney sweep can measure your flue and install a chimney cap with mesh sides that block animals and embers without choking the draft. Call (856) 344-1158 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. 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. It is not the same thing as the crown, which is the concrete or mortar slab that covers the top of the masonry.
The right cap depends on the chimney. 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.
If the problem goes deeper than it first looked, a Somerdale chimney sweep may also recommend chimney crown repair or chimney animal removal.

Call nowThe process
What happens during a cap installation
A cap that fits well and is fastened properly will stay on through years of wind.
Check the flue first
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. Getting the size right keeps the cap secure and the draft strong.
Choose the material
The cap is matched to the chimney, the appliance and the look of the house. The appliance using the flue affects the choice.
Check the crown
A cap needs a solid base, so the crown and tile are inspected. Small cracks can be sealed before the cap goes on.
Fasten 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
What chimney cap installation covers
Single flue caps
Caps made for a single flue that clamp or screw onto the tile for the typical one flue chimney.
Animal guard mesh
A heavy mesh screen blocks animals from nesting in the chimney and keep debris out too.
Multi flue caps
A larger cap that covers the entire crown and every flue under it keeps several flues covered under one lid.
Top sealing caps
A combined cap and damper closes the flue at the top for a tighter seal than an old throat damper.

Chimney Cap Replacement Somerdale, NJ
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. Swapping to stainless or copper means the new cap should outlast the old one by years.
Homeowners in Somerdale often find out about a failed cap when water or an animal shows up in the fireplace. When you call (856) 344-1158, 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 Somerdale, NJ
Spark arrestors are screened caps that trap glowing embers inside the chimney. 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. Local fire rules in dry or wooded areas may require a spark arrestor.
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. Cleaning or replacing the mesh restores the draft.

Chimneys in this climate
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: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Somerdale, NJ schedule a sweep in early fall, and a repair check after a hard winter.

Common questions about chimney cap installation
What is the difference between a chimney cap and a chimney crown?
They are two different parts: the crown is the masonry top of the chimney and the cap is the metal piece over the flue. A cap is a removable metal hood that keeps water and animals out of the flue itself. A chimney needs both, and a cracked crown can leak even with a good cap.
How long does a chimney cap last?
Lifespan depends mostly on the material. Galvanized caps rust much sooner, often within a handful of years. 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 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. 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.
Will a cap make my fireplace smoke?
The right cap, mounted with enough height above the flue, lets smoke out freely. Problems come from caps that sit too low, mesh that is clogged with soot or creosote, or a cap that is too small for the flue. Cleaning or resizing the cap usually fixes it.
