How to Read a Chimney Report

A Report Is Only Useful If You Can Read It

Plenty of Woodland Hills homeowners have a chimney report in a drawer that they never fully understood. It came from a home inspector during a purchase, or from a sweep company, and it uses words like "parging", "spalling" and "Level 2 recommended" without saying what any of them mean for the house. This guide walks through how to read one, ours or anyone's, and how to turn it into a decision about what to fix, what to watch and what to leave alone.

Start With the Scope

The first thing to look for is what the inspection covered. A good report states its level on the first page.

• - Level 1 means a visual check of the parts that can be reached without special tools: firebox, damper, the smoke chamber as far as a light reaches, outside masonry, crown and cap.
• Level 2 adds a camera run up the whole flue, plus the attic, crawlspace and roof areas beside the chimney.
• Level 3 means something was opened up, such as a wall panel or a section of masonry, to see a part no camera could reach.

These levels come from NFPA 211, the fire code standard for chimneys. If a report does not say which level it was, you cannot tell whether "no problems found" means the flue is sound or that nobody looked at it. Our reports put the level and a sentence about what it reached at the top of page one, along with anything we could not see and why, such as a cap that would not come off or a flue too offset for the camera to pass.

Find the Urgent Items First

Next, look for anything that should stop you lighting a fire. Some reports bury these in the middle. Ours list them on page one under fix before the next fire. Typical examples are a cracked firebox panel in a factory-built unit, a damper stuck shut, a flue blocked by a nest, a missing section of liner, or heavy glazed creosote.

If your report does not separate urgent items, read every finding and ask one question about each: is this a safety problem today, or wear that will become one later? If you cannot tell from the wording, that is a gap in the report, not in your understanding.

Read Each Finding as Three Parts

A useful finding has three parts: where it is, what it is, and why it matters. For example: "Open mortar joint between flue tiles at six feet above the damper, about an eighth of an inch wide, all around. Allows heat and gases to reach the masonry around the liner." That tells you location, size and consequence.

Compare that with "flue tiles deteriorated". It might be true, but you cannot price it, you cannot check it, and you cannot tell how bad it is. When a finding is that vague, look for the photo. If there is no photo, ask for one.

Every finding in our reports has a photo or a video still above it, the location in words, a size where one applies, and a one-sentence reason. Under it is one of three ratings:

• - Safe to use: working as it should today.
• Watch it: wear that is not urgent, with a note on when to look again.
• Fix before the next fire: repair it before the fireplace is used.

Words You Will See and What They Mean

• - Crown: the concrete or mortar slab on top of the chimney around the flue. Cracks here let water into the brick below.
• Spalling: brick faces flaking or popping off, usually from water freezing or salts. In the Valley it is more often from water and heat cycles than from frost.
• Parging: a smooth coat of refractory mortar on the smoke chamber walls. Missing parging leaves rough, stepped brick that catches creosote.
• Offset: a place where one liner section does not line up with the next. Common after earthquakes.
• Creosote stage: stage one is loose soot, stage two is flaky and crunchy, stage three is a hard glaze that needs special removal.
• Clearance: the distance between hot parts and anything that can burn, such as framing, a mantel or trim.

Turning Findings Into Next Steps

Once you know what each finding is, the next-step page should tell you what to do about it. A good one ties each recommendation to a finding number, names the service, and says whether the price is firm or needs a closer look. Ours do exactly that. For anything priced from our list, the figures are fixed: sweeps from $215, Level 1 inspections at $53, Level 2 at $380, installed caps at $160 to $650. Repairs like masonry, flashing and relining are quoted in writing from the photos where they show enough.

Three questions decide what happens next: which items are marked fix before the next fire, whether the photos show enough to price each repair, and whether you want a second bid. If you have a report from another company and want to know what it means or what it would cost to act on, send it to us with the photos. We will tell you which lines we can price from it and which need a visit.

Red Flags in Any Chimney Report

• - No inspection level stated.
• No photos, or photos with no location.
• Findings with no rating or urgency.
• A repair recommendation with no finding behind it.
• "Full rebuild recommended" with no photos showing the failed masonry.

None of these mean the inspector was wrong. They mean you cannot check the work, and you should ask for more before spending money.

A Report Worth Keeping

A clear report is useful long after the visit. It is the baseline the next inspector compares against, the record a buyer will ask for, and evidence for an insurer if something happens. Keep it with the house papers, along with any completion photos from repairs.
