Sweep or Inspection: Which First?

Two Different Visits

Every fall in Woodland Hills we get calls that start, "I need someone to look at my chimney." Some of those callers need a sweep. Some need an inspection. Many need both, and a few need neither yet. The two jobs are often mixed up, and booking the wrong one wastes time and money. This guide explains the difference and how to choose.

A chimney sweep is cleaning. Brushes and rods go up the flue, a vacuum runs at the fireplace opening, and creosote, soot and debris come out. Ours starts from $215 and includes before and after photos of the smoke chamber and lower liner, with a short sheet rating the damper, smoke shelf and cap.

A chimney inspection is evaluation. Nothing gets cleaned on purpose. The goal is to find out what condition the chimney is in and write it down. A Level 1 inspection, the visual check, costs $53. A Level 2, which adds a recorded camera run of the full flue and the attic and roof areas beside the chimney, costs $380.

When to Book a Sweep First

Book the sweep if you burn wood regularly and the main question is whether the flue is clean enough to keep using. Signs you are due:

• - You burned more than a dozen or so fires since the last sweep.
• The fireplace smells strongly of smoke on warm days, which is common in the Valley when summer heat bakes old deposits.
• You can see black, flaky material on the smoke shelf or the damper.
• Smoke has started rolling into the room when it did not before.

A sweep removes the fuel for a chimney fire. Our sweep also gives you a photo record of the lower flue and a rating on a few key parts, which is often enough for a chimney in regular use with no other concerns.

When to Book an Inspection First

Book an inspection first when the question is not cleanliness but condition:

• - You are buying or selling the house.
• There has been an earthquake, a chimney fire, or a hard windstorm since the last check.
• You see water stains near the chimney, rust on the damper, or white staining in the firebox.
• You plan to change the appliance or fuel, such as adding gas logs or an insert.
• You moved in recently and do not know the chimney's history.

In those cases, a sweep might clean a flue that has deeper problems and leave you none the wiser. The inspection tells you whether the chimney is fit to use and what it needs.

When You Need Both

Many West Valley chimneys need both, in one visit. A wood-burning fireplace that gets used every winter should be swept, and a Level 1 inspection at the same visit adds the outside masonry, crown and cap to the photo record. The flue is clean afterward, so the inspection sees more clearly.

If a Level 2 is needed, the order matters. Heavy creosote can hide cracks and joints from the camera, so on a heavily used flue we often sweep first and run the camera second, in the same visit. The report then shows the liner itself rather than the deposit on it.

What Changes the Price

Your bill follows two things: the visit type and the flue count. A single-flue sweep starts from $215. Adding a Level 1 is $53. A Level 2 is $380. A two-story hillside house with two fireplaces takes longer to document than a single-story ranch house with one, so say which you have when you book.

If you are not sure which you need, send us a photo of the fireplace and tell us why you are calling. We will recommend sweep, inspection, or both, and give you the price in writing before you book.

What You Get From Each

From a sweep:

• - A clean flue, smoke chamber and firebox.
• Before and after photos from matching angles.
• The creosote stage we found, written down.
• A rating on the damper, smoke shelf and cap.
• The next step named if the photos show a problem.

From an inspection:

• - A PDF report sent the same day.
• The inspection level and scope stated on page one.
• One photo and one sentence for each finding.
• Every finding rated safe to use, watch it, or fix before the next fire.
• A next-step page tied to numbered findings, with prices where the evidence allows.
• On a Level 2, the full video file.

Gas Fireplaces Are Different

If your fireplace burns gas, a sweep is rarely what you need. Gas burns cleanly and does not leave creosote. What a gas unit needs is a service visit: glass cleaned, burner ports cleared, logs placed as the manual shows, pilot checked, the vent cap outside cleared, and a carbon monoxide reading taken with it running. Gas logs in an old wood fireplace are the exception, since they vent up the existing chimney, which should still be inspected.

How Often

For a wood fireplace in regular use, plan on a sweep every year and an inspection every year, ideally together before the cool months. If you burn only a few fires a year, an inspection every year with a sweep when it shows the flue needs it is reasonable. After any of the events listed above, book an inspection whatever the calendar says.
