Damper 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.

Chimney Cap Installation Hightstown, NJ
Most chimneys in Hightstown should have a cap, and a local sweep can fit one that keeps rain, birds, raccoons and leaves out while letting smoke escape. One call to (609) 834-0024 reaches a nearby sweep who installs caps.
Without a cap, the top of a flue is open to rain, snow, leaves and wildlife. 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. 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. 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 Hightstown also turn up a need for 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.
Look inside
Nothing should be trapped below a new cap, so the flue is checked first. If birds are nesting, the timing of the job may change.
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.
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.
Inspect the top
A cap needs a solid base, so the crown and tile are inspected. Any damage found is pointed out to you.
Secure it
The cap is screwed or clamped to the flue tile, or anchored to the crown for outside mount models. It should not wobble when pushed, and you will hear when the mesh should be checked for soot.
What is included
Chimney cap options
Single flue caps
Caps made for a single flue that clamp or screw onto the tile for the typical one flue chimney.
Full crown caps
A cap that shades the full crown and all flues together works when flue tiles are short or uneven.
Stainless steel caps
Copper caps last a long time and weather to a natural patina so the cap does not need replacing every few years.
Wildlife screens
Screened sides stop wildlife from getting in and keep debris out too.

Chimney Cap Replacement Hightstown, NJ
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.
In Hightstown, a missing cap is often noticed only after a nest or a wet firebox appears. When you call (609) 834-0024, 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 Hightstown, 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. Check with your local fire department, since some areas require arrestors on wood burning chimneys.
Spark arrestor mesh needs occasional cleaning, because creosote and soot can build up on the screen and slow the draft. Smoke rolling back into the room can be a sign the screen is blocked. A Hightstown sweep can clean the mesh or replace a screen that has rusted through.

Chimney Cap Installation Near Me
In Hightstown, an open flue invites rain, leaves and nesting animals, especially when the fireplace sits unused for months. Homes in Hightstown and nearby towns such as Twin Rivers, Cranbury, Princeton Meadows and Concordia range from older brick chimneys that never had caps to newer ones with rusted galvanized caps, so a solid cap is one of the simplest ways to protect the flue.

How the weather here affects chimneys around Hightstown
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: 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. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Hightstown is usually booked in the fall, before the first cold night.

Chimney Cap Installation questions
Can a chimney cap cause draft problems?
A properly sized cap should not hurt the draft, and it can even help on windy days. 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 often do chimney caps need to be replaced?
Stainless steel and copper caps often last for decades with little upkeep. 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.
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 sweep can tell you what kind of bird it is and advise on timing. Capping after the birds migrate keeps the next season from repeating.
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. A cap is a removable metal hood that keeps water and animals out of the flue itself. Each protects a different part, so both should be in good shape.
Why should I put a cap on my chimney?
Chimney caps block water, debris and wildlife from getting into the flue while still letting smoke out. Water in the flue causes rust, crumbling mortar and odors, and animals can block the flue completely. For the cost of a small part, a cap prevents a lot of trouble.
