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.
A Cecilton chimney sweep can measure your flue and install a chimney cap with mesh sides that block animals and embers without choking the draft. Dial (443) 899-3075 to talk with a local chimney pro about a cap.
An uncapped chimney is an open hole in the roof, and plenty of things find their way into it. 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.
Caps are made of a lid that keeps precipitation out and wire mesh walls that let smoke and gases pass. It is not the same thing as the crown, which is the concrete or mortar slab that covers the top of the masonry.
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. Galvanized caps cost less up front but tend to rust, so stainless steel or copper is the longer lasting choice.
Depending on what the sweep finds, chimney cap installation in Cecilton, MD can go hand in hand with chimney crown repair and chimney animal removal.

Call nowPutting on a cap is quick work, but measuring and checking come 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.
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.
You choose between stainless steel and copper and between a single flue or full crown design. The appliance using the flue affects the choice.
A cap needs a solid base, so the crown and tile are inspected. Small cracks can be sealed before the cap goes on.
A single flue cap is tightened onto the tile, and crown mount caps are fastened into the masonry. It should not wobble when pushed, and you will hear when the mesh should be checked for soot.
Caps with a built in damper seal the top of the flue and cut drafts which helps where the throat damper is worn out.
Caps made for a single flue that clamp or screw onto the tile is the most common type on brick chimneys.
Mesh sides keep birds, squirrels, raccoons and bats out of the flue and keep debris out too.
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 also protects the crown from direct rain.
Plenty of chimneys already have a cap, but it may be rusted, bent or missing mesh. Look for rust stains on the crown, a tilted lid or gaps in the screen. A replacement in stainless steel or copper usually ends the cycle of rusting caps.
In Cecilton, a missing cap is often noticed only after a nest or a wet firebox appears. When you call (443) 899-3075, mention whether the old cap is still on the chimney and what the fireplace or stove burns. A flue left uncapped for a while is worth sweeping or checking for nests.
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.
Spark arrestor mesh needs occasional cleaning, because creosote and soot can build up on the screen and slow the draft. If smoke suddenly starts spilling into the room, a clogged screen is one of the first things to check. A Cecilton 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, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Cecilton is usually booked in the fall, before the first cold night.
Small chimney problems caught early usually stay small repairs.
Local sweeps see the same chimney types and weather wear across Cecilton and nearby towns.
