Chimney Cap Installation Burlington, NJ
A chimney sweep in Burlington can install a metal cap over your flue with mesh sides that block animals and embers without choking the draft. Call (609) 699-0240 to reach a local chimney sweep.
A chimney with no cap lets in water, debris and animals every day of the year. Every storm sends water down the flue, and over time that means rusted dampers, wet masonry and a musty fireplace. Birds, squirrels and raccoons see the open top as a safe place to nest.
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.
If the problem goes deeper than it first looked, a Burlington 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
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.
Take measurements
The flue tile is measured across the outside and for how far it sticks above the 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. Wood, gas and oil flues can each call for a different cap.
Inspect the top
While on the roof, the sweep looks for cracks in the crown and loose flue tiles. Small cracks can be sealed before the cap goes on.
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
What chimney cap installation covers
Full crown caps
Outside mount caps that span the whole top of the chimney works when flue tiles are short or uneven.
Flue tile caps
A simple cap for one flue extending above the crown for the typical one flue chimney.
Damper caps
Caps with a built in damper seal the top of the flue and cut drafts which helps where the throat damper is worn out.
Copper caps
Stainless and copper caps resist rust far better than galvanized steel so the cap does not need replacing every few years.

Chimney Cap Replacement Burlington, NJ
Caps do not last forever, especially the galvanized ones that come on many homes. 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.
If you are in Burlington, a cap that blew off in a storm or one that animals pried loose is worth replacing before the next rain. Calling (609) 699-0240 with a few details, such as how many flues there are and what fuel you burn, helps the sweep plan the job. The sweep can also check whether anything got into the flue while the cap was missing.

Spark Arrestor Installation Burlington, NJ
Spark arrestors are screened caps that trap glowing embers inside the chimney. Fire standards like NFPA 211 call for mesh openings of roughly three eighths to one half inch, which balances ember control with airflow. Some communities with wildfire risk require them on every wood burning chimney.
A screen that clogs with soot can push smoke back into the house, so the mesh should be checked during sweeping. A smoky fireplace after years of good draft can point to a clogged screen. The fix is usually cleaning the screen or swapping in a new one.

How the weather here affects chimneys around Burlington
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: rain and melting snow soak into the crown and joints, then freeze and push them apart, and each winter widens the cracks a little more. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in Burlington, NJ schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Cap Installation FAQ
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.
What is the difference between a chimney cap and a chimney crown?
The crown is the slab of concrete or mortar that covers the top of the masonry around the flue. The cap is the metal cover with mesh sides that sits over the flue opening above the crown. Each protects a different part, so both should be in good shape.
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. Ask the sweep to check the cap whenever the chimney is cleaned.
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 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.
What does a chimney cap actually do?
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.
