Chimney Cap Installation Long Valley, NJ
A Long Valley chimney sweep can measure your flue and install a chimney cap with mesh sides that block animals and embers without choking the draft. Call (908) 867-1003 to reach a local chimney sweep.
Without a cap, the top of a flue is open to rain, snow, leaves and wildlife. Water that falls into an open flue rusts metal parts, breaks down mortar and leaves a damp, smoky odor in the room. 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. 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.
Many chimney cap installation calls in Long Valley also turn up a need for chimney crown repair or chimney animal removal.

How chimney cap installation works
Putting on a cap is quick work, but measuring and checking come first.
Check the flue first
Before the cap goes on, the flue is checked for animals, nests and blockages. An occupied flue gets handled before capping.
Size the cap
The flue tile is measured across the outside and for how far it sticks above the crown. The cap needs enough height above the flue for smoke to escape freely.
Select a style
The cap is matched to the chimney, the appliance and the look of the house. Wood, gas and oil flues can each call for a different cap.
Inspect the top
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
Chimney cap options
Damper caps
A combined cap and damper closes the flue at the top which helps where the throat damper is worn out.
Full crown caps
A larger cap that covers the entire crown and every flue under it also protects the crown from direct rain.
Copper caps
Stainless steel holds up to weather and flue gases for many years which makes them worth the higher upfront cost.
Wildlife screens
A heavy mesh screen blocks animals from nesting in the chimney while letting smoke and gases out.

Chimney Cap Replacement Long Valley, NJ
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. A replacement in stainless steel or copper usually ends the cycle of rusting caps.
If you are in Long Valley, a cap that blew off in a storm or one that animals pried loose is worth replacing before the next rain. When you call (908) 867-1003, mention whether the old cap is still on the chimney and what the fireplace or stove burns. A flue left uncapped for a while is worth sweeping or checking for nests.

Spark Arrestor Installation Long Valley, NJ
Spark arrestors are screened caps that trap glowing embers inside the chimney. Mesh that is too fine clogs with soot, and mesh that is too open lets embers through, so the size follows fire safety standards. Local fire rules in dry or wooded areas may require a spark arrestor.
Over time, soot collects on the screen, which is why sweeps check the mesh whenever the flue is cleaned. 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 Long Valley
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. 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. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in Long Valley is usually booked in the fall, before the first cold night.

Chimney Cap Installation questions
Can a chimney cap cause draft problems?
Well fitted caps rarely cause draft trouble. 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.
How long does a chimney cap last?
A good stainless steel or copper cap can last as long as the chimney itself in many cases. Galvanized and painted steel caps tend to rust within several years, especially near the coast or with oil fired appliances. A quick check at each chimney sweeping catches damage early.
What does a chimney cap actually do?
The main job of a cap is to keep water and animals out 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 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.
What should I do if birds are nesting in my chimney?
If the birds are chimney swifts, federal law protects them, and they have to be left alone until nesting season ends. A chimney sweep can identify the bird and tell you when the flue can be cleared. After they leave, the nest is removed and a cap goes on.
