Sweep vs. repair budget

Angi puts the national average chimney repair at $455. A basic inspection on its own runs $100 to $300 in HomeGuide's repair guide, and a comprehensive structural inspection more than $1,000. HomeGuide's example: a $200 repair caught at a sweep can prevent a $2,000 repair later.

What a chimney sweep does

A chimney sweep removes soot and creosote from the flue, firebox and smoke chamber. Creosote is a tar-like byproduct of burning wood. It builds up inside the chimney and can catch fire.

Sweep vs. inspection

Many companies offer both. A sweeping cleans the chimney, while an inspection checks its condition. Chimney inspections are often described in three levels:

• Level 1: a basic visual check of accessible parts.
• Level 2: a more detailed check, often with a camera. Common when buying a home or changing fuel.
• Level 3: opening parts of the structure when a serious problem is suspected.

Signs your chimney needs cleaning

• A strong smell from the fireplace, especially in humid weather.
• Black flakes or soot falling into the firebox.
• Smoke coming into the room instead of going up the chimney.
• Fires that are hard to start or burn poorly.

What affects the price

• Single or multiple flues.
• Fireplace, wood stove or insert.
• Amount of creosote buildup.
• Whether an inspection or camera scan is added.

Questions to ask

1. Are you certified as a chimney sweep?
2. Will you provide a written report and photos?
3. How do you protect the room from soot?

In Texas

With mild winters, many Texas fireplaces are used lightly, but they still need checking. Animals and birds may also nest in unused chimneys, so a sweep before the first fire of the year is a good idea.

What creosote is

When wood burns, it releases smoke, vapors and unburned particles that condense on the cooler walls of the chimney as creosote. It builds up in layers and is highly flammable. A thin, flaky layer is easier to remove. A thick, tarry or glazed layer is harder to clean and more dangerous, and may need special removal products or tools. Burning wet or unseasoned wood, burning small, smoldering fires and having a liner that is too large all increase creosote buildup.

Burning habits that keep the chimney cleaner

• Burn only dry, seasoned hardwood.
• Avoid burning trash, cardboard, painted wood or treated lumber.
• Build hot, efficient fires rather than letting fires smolder.
• Open the damper fully before lighting a fire.
• Keep the area around the chimney top clear of overhanging branches.

How often to sweep

The National Fire Protection Association recommends that chimneys, fireplaces and vents be inspected at least once a year and cleaned as needed. Heavy users of wood stoves may need cleaning more than once a season. Gas fireplaces produce less soot but still need inspection, because the vents can be blocked by nests, debris or deteriorated parts.

What happens during a sweep

The sweep lays down drop cloths, sets up a vacuum to control dust, and uses brushes and rods to clean the flue from the top, the bottom or both. The smoke chamber, smoke shelf and firebox are cleaned. The damper is checked. Many sweeps also do a basic visual inspection and point out problems such as cracked tiles, a missing cap or damaged masonry.

Signs of a chimney fire

Loud popping or roaring, dense smoke and a strong hot smell can signal a chimney fire. Some chimney fires are slow-burning and go unnoticed. After a suspected chimney fire, stop using the fireplace and have a Level 2 inspection before using it again.

Gas fireplaces and inserts should be inspected each year. Technicians check the vent, burner, pilot or igniter, glass and gaskets.

Animals and blockages

Birds, squirrels and raccoons often nest in chimneys that lack a cap, especially in spring. Nests block the flue and can catch fire or push smoke and carbon monoxide back into the house. Some birds, like chimney swifts, are protected by federal law, so removal may have to wait until they leave after nesting season. A sweep can remove nests when it is allowed and install a cap with a mesh screen to keep animals out. Leaves and debris can also collect at the smoke shelf, which the sweep clears during cleaning.

Choosing a chimney sweep

Look for a sweep certified by the Chimney Safety Institute of America (CSIA) or a similar program, with insurance and good local reviews. Be cautious of very cheap offers that lead to high-pressure sales for repairs. Ask for photos or video of any problem the sweep says needs fixing.
