By what you notice

Symptoms that cross more than one system

A smell or a drip doesn’t always come from where you’d expect. These groups put related symptoms side by side, whichever appliance they belong to.

Water, stains and rust

Rain getting in somewhere between the roof line and the top of the chimney, or into the dryer duct.

Smells and odors

Humidity, creosote, animals, gas or overheated lint, and which of those can’t wait.

Smoke, drafts and blockages

Smoke rolling into the room, cold or hot air from an unused fireplace, and a flue that may be obstructed.

Won’t light, won’t run, won’t close

Gas fireplaces that won’t start or stay lit, stuck dampers and doors, and dryers without airflow.

Animals and noises

Birds, raccoons and squirrels in the flue, plus the sounds that point to a loose cap or a failing blower.

Visible damage

Cracks, crumbling brick, a leaning chimney, broken fireplace glass and damage after a storm.

FAQ

Questions about diagnosing a problem

Straight answers. If yours isn’t here, send it with an estimate request and we’ll answer it directly.

Which chimney, fireplace or dryer vent problems can’t wait?

A gas smell, a carbon monoxide alarm, signs of a chimney fire (a roaring sound, dense smoke or glowing flakes from the top), a dryer that smells like burning, and a chimney that is visibly leaning or missing bricks after a storm. Leave gas smells to the utility or 911 first. Most other symptoms, like a slow leak, a musty smell or a sticky damper, can be booked normally as long as you stop using the appliance until it’s checked. See signs of a chimney fire.

Why can the same symptom have different causes in two similar homes?

Because the systems behind them differ. Water in a masonry fireplace often starts at the crown or flashing, while the same drip in a factory-built unit usually starts at the chase cover or storm collar. A smell can be creosote in one home and a trapped animal or damp soot in another. That’s why each guide lists the checks that separate the causes before naming a repair.

Is it the dryer or the vent when clothes stay damp?

Usually the vent. If the dryer heats but clothes need a second cycle, and the outside flap barely opens while it runs, the airflow is restricted somewhere in the duct. If the drum stays cold or won’t tumble, it’s the appliance. The dryer or dryer vent guide walks through the difference.
