Single flue caps
A simple cap for one flue extending above the crown for the typical one flue chimney.
A Perkasie chimney sweep can measure your flue and install a chimney cap that keeps rain, birds, raccoons and leaves out while letting smoke escape. Call (267) 452-8534 to reach a local chimney sweep.
A chimney with no cap lets in water, debris and animals every day of the year. Water that falls into an open flue rusts metal parts, breaks down mortar and leaves a damp, smoky odor in the room. Birds, squirrels and raccoons see the open top as a safe place to nest.
The cap itself is a simple part: a solid top to shed water, mesh sides to block animals and a base that fastens to the chimney. 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. Stainless steel and copper last far longer than galvanized or painted steel, which rusts and streaks the masonry within a few years.
If the problem goes deeper than it first looked, a Perkasie chimney sweep may also recommend chimney crown repair or chimney animal removal.

Call nowPutting on a cap is quick work, but measuring and checking come first.
Before the cap goes on, the flue is checked for animals, nests and blockages. An occupied flue gets handled before capping.
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.
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.
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.
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.

Stainless steel holds up to weather and flue gases for many years so the cap does not need replacing every few years.
Outside mount caps that span the whole top of the chimney works when flue tiles are short or uneven.
A combined cap and damper closes the flue at the top for better energy savings.
A heavy mesh screen blocks animals from nesting in the chimney without blocking the draft.
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.
In Perkasie, a missing cap is often noticed only after a nest or a wet firebox appears. When you call (267) 452-8534, 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.
The spark arrestor is the screen around the cap that catches hot embers before they can drift onto the roof or yard. 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.
Over time, soot collects on the screen, which is why sweeps check the mesh whenever the flue is cleaned. A smoky fireplace after years of good draft can point to a clogged screen. A Perkasie sweep can clean the mesh or replace a screen that has rusted through.

Winters here are long and cold, and the heating season usually runs from October well into April. 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. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Perkasie, PA schedule a sweep in early fall, and a repair check after a hard winter.
A chimney problem fixed early rarely spreads to the masonry, the liner or the house.
Chimney sweeps in Perkasie know the chimneys and fireplaces common in local homes.
Ask the sweep about the cause, the options and the estimate before work starts.
