Chimney Cap Installation Glenside, PA
A Glenside 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) 633-0161 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. Squirrels, raccoons and birds nest in open flues, and their nests can block smoke from escaping.
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. The crown seals the top of the brick, while the cap protects the opening of the flue itself.
The right cap depends on the chimney. One flue sticking up from the crown takes a single flue cap, and several flues or a short tile usually call for a full crown cap. Painted and galvanized steel rust out, while stainless and copper caps hold up for decades.
Many chimney cap installation calls in Glenside also turn up a need for chimney crown repair or chimney animal removal.

What happens during a cap installation
Here is how a chimney sweep usually handles a cap installation.
Clear the flue
Nothing should be trapped below a new cap, so the flue is checked first. 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. The cap needs enough height above the flue for smoke to escape freely.
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.
Look at the crown
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.
Fasten the cap
The cap is screwed or clamped to the flue tile, or anchored to the crown for outside mount models. A well fastened cap stays put in high wind, and the sweep can tell you how often to check the screen.
What is included
Chimney cap options
Top sealing caps
Some caps include a top sealing damper that closes off the flue when the fireplace is not in use for better energy savings.
Full crown caps
A larger cap that covers the entire crown and every flue under it works when flue tiles are short or uneven.
Copper caps
Stainless and copper caps resist rust far better than galvanized steel without staining the brick below.
Animal guard mesh
Mesh sides keep birds, squirrels, raccoons and bats out of the flue without blocking the draft.

Chimney Cap Replacement Glenside, PA
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. Swapping to stainless or copper means the new cap should outlast the old one by years.
Homeowners in Glenside often find out about a failed cap when water or an animal shows up in the fireplace. It helps to tell the sweep whether the chimney has one flue or several and what is vented through it. Debris that fell in while the cap was off may need to be cleared out first.

Spark Arrestor Installation Glenside, PA
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. Check with your local fire department, since some areas require arrestors on wood burning chimneys.
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. The fix is usually cleaning the screen or swapping in a new one.

What the local climate does to a chimney
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, which is how cracks, loose bricks and leaks start. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Glenside, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Cap Installation questions
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. A chimney needs both, and a cracked crown can leak even with a good cap.
Can a cap go on if there are birds in the chimney?
Chimney swifts are a protected migratory bird, so their nests cannot be removed while they are in use. A sweep can tell you what kind of bird it is and advise on timing. After they leave, the nest is removed and a cap goes on.
How often do chimney caps need to be replaced?
A good stainless steel or copper cap can last as long as the chimney itself in many cases. Galvanized caps rust much sooner, often within a handful of years. Storms and animals can damage any cap, so it is worth having it checked when the chimney is swept.
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. Ask the sweep to check the cap whenever the chimney is cleaned.
What does a chimney cap actually do?
The main job of a cap is to keep water and animals out of the chimney. Water damage and animal nests are two of the most common chimney problems, and both are largely prevented by a cap. Most chimney sweeps recommend a cap on every flue.
