What's the difference between Level 1, 2, and 3 chimney inspections?

They're tiers of access, defined in NFPA 211. Level 1 covers readily accessible areas — the routine annual check when nothing has changed. Level 2 adds a camera scan of the flue interior plus attics and crawl spaces, and it's required at property sale, after a fire, or when the appliance or fuel changes. Level 3 involves removing components or finish materials to reach a suspected hidden hazard. Each tier has to be justified by the one below it.

When is a Level 2 inspection actually required?

NFPA 211 names the triggers: sale or transfer of the property, after a chimney fire or operating malfunction, after external events like storms or seismic activity, and whenever you change the fuel type or connect a new appliance. If any of those apply, a Level 1 isn't sufficient — the standard wants the flue interior scanned, not just eyeballed from the top and bottom.

What do I actually get after an inspection?

A written report, standard turnaround 48 hours. It lists every checkpoint with a pass or fail verdict, a photo behind each finding, the relevant code or standard reference, and — when something fails — what correcting it involves. It's a document you can forward to an insurer, a buyer, or another contractor for a competing bid. Nothing we say on-site counts until it's in the report.

How often does a chimney really need sweeping?

The honest answer is: when measurement says so. NFPA 211 requires annual inspection, but sweeping is triggered by creosote depth — 1/8 inch is the threshold. A fireplace burning most nights all season usually hits that in about a year. Occasional weekend fires might take two or three. We measure at each inspection and only recommend a sweep the measurement supports.

My home inspector already looked at the chimney. Isn't that enough?

General home inspectors do visual checks from the ground and the firebox — their own standards of practice put chimney flue interiors outside scope. The failures that cost real money, like gapped flue tiles and hidden cracking, only show on a camera scan. That's why NFPA 211 specifies a Level 2 at property transfer. Plenty of chimneys pass; the point is knowing before you close, not after.

Can a chimney partially pass an inspection?

Yes — verdicts are per system, not per chimney. The flue can pass while the crown fails, or the masonry can be sound while the cap is missing. The report breaks it down that way so you can prioritize: what's a safety item, what's a water-intrusion item that gets worse each season, and what's cosmetic. You fix in that order, or we'll tell you why we'd sequence it differently.

Will my insurance company accept your reports?

Our packets use the format adjusters work from — dated photos, measurements, code references, and an itemized repair scope. That's the documentation half. What we can't do is guarantee any claim outcome; that decision belongs to your carrier and your policy language. What we can promise: the file will say what the evidence says, and we'll walk the site with your adjuster if scope gets disputed.

Why won't you quote repair prices over the phone?

Because we'd be guessing, and a guessed number always turns into a fight later. Our quotes are built from inspection findings — each line names the defect, the fix, and the standard it satisfies. That only works if the inspection comes first. Inspection fees themselves are flat and confirmed when you book, so you're never wondering what the visit costs.

Chimney Standard is a new company. Why should I trust you?

Fair question, and we won't dodge it. The brand is new, so we can't point at decades of company history — the field experience is in the people, with 15+ years on Texas chimneys among our inspectors and the licensed & insured contractors we work with. What we'd point to instead is the paperwork. Every verdict comes with photos and a citation you can check, or hand to another sweep for a second opinion. Trust the document, not the logo.

Are you the cheapest chimney company in Dallas?

No, and we're not trying to be. A measured, photographed, written-up inspection takes more time than a flashlight glance and a verbal all-clear, and that time is in the price. Where we compete is on the other side of the ledger: you'll never pay for a repair that isn't tied to a documented defect, and we regularly tell people their chimney passed and needs nothing.

What is creosote, and why does 1/8 inch matter?

Creosote is the tar-like residue wood smoke deposits inside a flue. It comes in stages — flaky first-degree through hardened third-degree glaze — and it's flammable at every stage. NFPA 211 sets 1/8 inch as the point where buildup can sustain a chimney fire, which can crack flue tiles in seconds and burn hotter than 2,000°F. That's why we measure depth instead of guessing from soot color.

How do I know if my chimney liner has failed?

You mostly can't from the outside — liner failure hides. The tells a camera scan picks up: gaps between clay tiles, cracked or shaling tile faces, and mortar joints washed out by acidic flue condensate. Symptoms upstairs can include smoke odor in adjacent rooms or bits of tile in the firebox. If the scan shows failure, relining with a UL 1777-listed stainless system is the recognized fix.

Do gas fireplaces need inspections too, or just wood-burning ones?

Gas needs them too — the failure mode is just quieter. Gas exhaust carries acidic water vapor that eats clay liners and mortar joints from the inside, and a blocked or corroded flue routes carbon monoxide back into the house instead of out of it. No visible soot doesn't mean no problem. NFPA 211's annual inspection requirement covers all fuel types for a reason.

What's the 3-2-10 rule?

It's the code shorthand for chimney termination height: the flue must extend at least 3 feet above the point where it passes through the roof, and be at least 2 feet taller than anything — roof line, dormer, neighboring structure — within 10 feet horizontally. Chimneys cut short by a remodel or a settled addition draft poorly and can pull smoke back into the room. It's a tape-measure check, and we run it on every roof visit.

What happens if my chimney fails the inspection?

You get the evidence and the decision stays yours. The report shows each failed item with photos and its code reference, and the quote maps to those findings line by line — approve all, some, or none. We'll flag which items are safety-critical versus which can wait a season. The only non-negotiable is honesty in the document: if a flue isn't safe to use, the report says so plainly.

Who actually performs the repair work?

Repairs run through licensed & insured contractors working to the written spec in your report — mortar type, liner sizing, flashing detail, all named before work starts. Our job is the standard on both ends: define the scope from documented findings, then verify the finished work against the same criteria and photograph the closeout. You end up with a before-and-after file, not just an invoice.

How fast can I get a report, and can you meet a real-estate deadline?

Standard turnaround is 48 hours from inspection to written report. If you're inside an option period, say so when you book — we schedule against your deadline and flag anything that threatens it up front rather than the day before. What we won't do is compress the inspection itself; a rushed scan produces a report nobody should rely on.

What should I do right after a chimney fire?

Stop using the fireplace immediately, even if the fire seemed to burn out on its own — a chimney fire can crack flue tiles you can't see. Then get it inspected before the next burn; NFPA 211 calls for a Level 2 minimum after any chimney fire. Save the timeline: date, what you observed, any fire-department response. That record matters for your insurance claim, and we'll fold it into the damage documentation.
