Chimney Sweeping
Chimney Odor Removal Sewickley, PA
Most fireplace odors in Sewickley homes come from creosote deposits, water in the flue or debris, and they can be fixed by sweeping, deodorizing and sealing the chimney by cleaning the flue and fixing whatever lets the smell drift indoors. Call (412) 663-3115 to reach a local chimney sweep.
The most common chimney smell is the sharp, smoky, asphalt-like odor of creosote, and it is usually worst in hot, humid weather. Moist air releases the smell from soot and creosote, and it finds its way past the damper into the house. A thorough sweeping removes most of it, and a deodorizing treatment can take care of what soaks into the masonry.
The smell only reaches the room because air is flowing down the flue instead of up. In a tight house, every exhaust fan pulls a little air down the chimney, along with the smell. Most traditional dampers leak even when closed. Many sweeps recommend a top-sealing damper for this reason.
A musty or sour smell points to water rather than creosote. Water that gets into a chimney mixes with ash and debris and keeps the masonry damp. Deodorizing helps only after the water is stopped.
Many chimney odor removal calls in Sewickley also turn up a need for chimney cleaning or chimney waterproofing.

What happens during chimney odor removal
Here is how a sweep usually tracks down and removes a chimney odor.
Diagnose the smell
The sweep asks when the smell shows up, what it smells like and what makes it worse. Damper, cap and crown condition all factor in.
Clean the flue
The flue, smoke chamber and smoke shelf are swept to remove creosote and soot. Debris on the smoke shelf is a frequent hidden source.
Take out remains
Nests, droppings or animal remains are removed from the flue and smoke shelf. Chimney swifts are a protected migratory bird, so their nests can only be removed after nesting season, and the sweep will advise on timing.
Apply a deodorizer
For odor that soaked into the brick, a deodorizer made for chimneys is used. It works best on a freshly swept chimney.
Fix the cause
A cap, a top-sealing damper or a leak repair keeps the smell from coming back. Glass doors on the fireplace can help too.
What is included

Fireplace Odor Removal Sewickley, PA
A fireplace that smells is often holding old ash, soot on the walls or debris on the smoke shelf. Clearing out the ash, sweeping the smoke chamber and treating the firebox brick with a deodorizer handles most cases. In the meantime, an open box of baking soda in the firebox and a closed damper may help a little.
If you are in Sewickley, it helps to mention when the smell started and whether it changes with the weather. If the smell is like rotten eggs, treat it as a possible gas leak: get out, do not flip switches or use flames, and call the gas company or 911 once you are outside. Remember that carbon monoxide is odorless, so CO alarms are the only reliable warning.

How the weather here affects chimneys around Sewickley
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: 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 Sewickley, PA schedule a sweep in early fall, and a repair check after a hard winter.

Common questions about chimney odor removal
Is a chimney smell dangerous?
A creosote smell itself is mostly an unpleasant nuisance, but the creosote behind it is fuel for a chimney fire. A gas or rotten egg smell is different: leave the house, avoid switches and flames and call the gas utility or 911 from outside. Keep CO alarms working, since carbon monoxide cannot be smelled.
Why does my fireplace smell damp after it rains?
Musty smells point to moisture, often from a missing cap, cracked crown or leaky flashing. Damp brick and debris can develop mold over time. Fixing the leak and letting the chimney dry out is what stops the smell.
Why does my fireplace smell worse when it is hot out?
Creosote in the flue gives off a stronger smell in hot, humid weather. Exhaust fans and air conditioning can draw air down the flue and carry the odor inside. A sweeping at the end of the burning season, plus a tighter damper, usually solves it.
How do I get rid of a chimney smell?
Start by removing the source, which usually means a full sweeping of the flue and smoke shelf. A chimney deodorizer can then treat odor that soaked into the masonry. To keep the smell from returning, the chimney may need a cap, a better damper or a fix for leaks.
What does it smell like when an animal dies in a chimney?
Animal remains create a foul, rotten smell, sometimes along with flies around the fireplace. A sweep removes the remains and cleans the area. Installing a cap prevents a repeat.
