Chimney Cap Installation Folsom, PA
A chimney sweep in Folsom can install a metal cap over your flue that keeps rain, birds, raccoons and leaves out while letting smoke escape. Dial (484) 470-7034 to talk with a local chimney pro about a cap.
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. 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.
The right cap depends on the chimney. 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.
Chimney Cap Installation is often paired with chimney crown repair and chimney animal removal, depending on the cause.

How chimney cap installation works
Putting on a cap is quick work, but measuring and checking come first.
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.
Size the cap
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.
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.
Look at the crown
The crown and the top of the flue are checked so the cap is not mounted on failing masonry. Crown repairs are easier to handle at the same time.
Install the cap
The cap is screwed or clamped to the flue tile, or anchored to the crown for outside mount models. Raccoons can pull off a loose cap, so it is set tight and checked before the sweep leaves the roof.
What is included
What chimney cap installation covers
Wildlife screens
Mesh sides keep birds, squirrels, raccoons and bats out of the flue while letting smoke and gases out.
Copper caps
Copper caps last a long time and weather to a natural patina which makes them worth the higher upfront cost.
Top sealing 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.
Single flue caps
Caps made for a single flue that clamp or screw onto the tile for the typical one flue chimney.

Chimney Cap Replacement Folsom, PA
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. Upgrading the material is the main way to avoid replacing the cap again soon.
In Folsom, a missing cap is often noticed only after a nest or a wet firebox appears. Calling (484) 470-7034 with a few details, such as how many flues there are and what fuel you burn, helps the sweep plan the job. A flue left uncapped for a while is worth sweeping or checking for nests.

Spark Arrestor Installation Folsom, PA
The spark arrestor is the screen around the cap that catches hot embers before they can drift onto the roof or yard. The NFPA 211 standard sets a mesh size that is small enough to stop embers but large enough not to clog quickly, about half an inch or a little less. Check with your local fire department, since some areas require arrestors on wood burning chimneys.
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. Cleaning or replacing the mesh restores the draft.

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: 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. That is why chimney cleaning in Folsom is usually booked in the fall, before the first cold night.

Chimney Cap Installation FAQ
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.
Is a chimney crown the same as a cap?
A crown is part of the masonry: it seals the top of the brick and slopes water away from the flue. The cap sits on or over the crown and covers only the opening. Having one does not replace the other.
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 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 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. After they leave, the nest is removed and a cap goes on.
What does a chimney cap actually do?
Chimney caps block water, debris and wildlife from getting into the flue while still letting smoke out. Water damage and animal nests are two of the most common chimney problems, and both are largely prevented by a cap. For most homes, a cap is one of the simplest protections a chimney can have.
