Chimney Cap Installation Delmont, PA
A chimney sweep in Delmont can install a metal cap over your flue that keeps rain, birds, raccoons and leaves out while letting smoke escape. Dial (724) 412-9258 to talk with a local chimney pro about a cap.
A chimney with no cap lets in water, debris and animals every day of the year. 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.
A chimney cap is a metal hood with mesh sides that sits over the flue opening. 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. 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
A cap that fits well and is fastened properly will stay on through years of wind.
Look inside
The sweep checks that the flue is clear of nests and debris before closing it in. An occupied flue gets handled before capping.
Size the cap
The sweep measures the length, width and height of the flue tile or crown. A cap that is too small will not fit, and one that sits too low can restrict draft.
Pick the right cap
The cap is matched to the chimney, the appliance and the look of the house. The appliance using the flue affects the choice.
Check the crown
The crown and the top of the flue are checked so the cap is not mounted on failing masonry. Any damage found is pointed out to you.
Fasten the cap
A single flue cap is tightened onto the tile, and crown mount caps are fastened into the masonry. Raccoons can pull off a loose cap, so it is set tight and checked before the sweep leaves the roof.
What is included
Chimney cap options
Wildlife screens
Mesh sides keep birds, squirrels, raccoons and bats out of the flue while letting smoke and gases out.
Multi flue caps
Outside mount caps that span the whole top of the chimney also protects the crown from direct rain.
Copper caps
Copper caps last a long time and weather to a natural patina which makes them worth the higher upfront cost.
Flue tile caps
Caps made for a single flue that clamp or screw onto the tile for the typical one flue chimney.

Chimney Cap Replacement Delmont, PA
Caps do not last forever, especially the galvanized ones that come on many homes. Torn screens, corroded lids and loose fasteners are the usual reasons a cap needs replacing. A replacement in stainless steel or copper usually ends the cycle of rusting caps.
If you are in Delmont, a cap that blew off in a storm or one that animals pried loose is worth replacing before the next rain. Calling (724) 412-9258 with a few details, such as how many flues there are and what fuel you burn, helps the sweep plan the job. Debris that fell in while the cap was off may need to be cleared out first.

Spark Arrestor Installation Delmont, PA
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. 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.

How the weather here affects chimneys around Delmont
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, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in Delmont, PA schedule a sweep in early fall, and a repair check after a hard winter.

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. Trouble usually traces back to a clogged screen or a cap that is undersized or mounted too close to the flue opening. A sweep can clean the mesh or switch to a better fitting cap.
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.
What is the difference between a chimney cap and a chimney crown?
They are two different parts: the crown is the masonry top of the chimney and the cap is the metal piece over the flue. A cap is a removable metal hood that keeps water and animals out of the flue itself. Having one does not replace the other.
Does my chimney really need a cap?
The main job of a cap is to keep water and animals out of the chimney. 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.
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 chimney sweep can identify the bird and tell you when the flue can be cleared. After they leave, the nest is removed and a cap goes on.
