Chimney Cap Installation DuBois, PA
Most chimneys in DuBois should have a cap, and a local sweep can fit one with mesh sides that block animals and embers without choking the draft. Dial (814) 913-0171 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. Rain runs straight down the flue, where it rusts dampers, soaks the smoke chamber and mixes with soot to make a sour smell. Squirrels, raccoons and birds nest in open flues, and their nests can block smoke from escaping.
Caps are made of a lid that keeps precipitation out and wire mesh walls that let smoke and gases pass. The crown seals the top of the brick, while the cap protects the opening of the flue itself.
Not every cap fits every chimney, so sizing and style matter. 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.
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.
Clear the flue
Before the cap goes on, the flue is checked for animals, nests and blockages. If birds are nesting, the timing of the job may change.
Take measurements
Measurements of the flue tile, or of the whole crown, decide which cap fits. The cap needs enough height above the flue for smoke to escape freely.
Pick the right cap
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
A cap needs a solid base, so the crown and tile are inspected. Any damage found is pointed out to you.
Secure it
The cap is attached firmly so wind and animals cannot pry it loose. Raccoons can pull off a loose cap, so it is set tight and checked before the sweep leaves the roof.
What is included
Types of chimney caps
Wildlife screens
Screened sides stop wildlife from getting in without blocking the draft.
Stainless steel caps
Stainless steel holds up to weather and flue gases for many years which makes them worth the higher upfront cost.
Single flue caps
A cap that fits over one flue tile and fastens to it and keeps the crown visible.
Multi flue caps
Outside mount caps that span the whole top of the chimney keeps several flues covered under one lid.

Chimney Cap Replacement DuBois, 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.
If you are in DuBois, a cap that blew off in a storm or one that animals pried loose is worth replacing before the next rain. When you call (814) 913-0171, 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.

Spark Arrestor Installation DuBois, PA
A spark arrestor is the mesh screen on a chimney cap that stops burning embers from leaving the flue and landing on the roof or nearby trees. 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. Smoke rolling back into the room can be a sign the screen is blocked. Cleaning or replacing the mesh restores the draft.

What the local climate does to a chimney
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. 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, and each winter widens the cracks a little more. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in DuBois, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Cap Installation FAQ
How often do chimney caps need to be replaced?
Lifespan depends mostly on the material. Cheaper galvanized steel caps rust out faster, and flue gases from some appliances speed that up. A quick check at each chimney sweeping catches damage early.
Will a cap make my fireplace smoke?
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. Cleaning or resizing the cap usually fixes it.
Can a cap go on if there are birds in the chimney?
Some chimney birds, especially chimney swifts, are protected, which limits what can be done during nesting season. The sweep will advise on when it is legal to clear the nest. Capping after the birds migrate keeps the next season from repeating.
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. For the cost of a small part, a cap prevents a lot of trouble.
Is a chimney crown the same as a cap?
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.
