These are the questions we hear most from homeowners across St. Louis, answered plainly so you know what to expect before anyone touches your chimney. If your question isn't here, call (866) 596-7310. We answer 24/7.
Pricing & Cost FAQs
A standard chimney sweep in St. Louis typically runs $150 to $300 for a single flue, and a level 2 inspection with camera typically falls in the $250 to $500 range. Those are estimated ranges, not a quote. The written estimate you get before booking sets the final price, and that estimate is free. St. Louis homes with masonry chimneys and liners that haven't been touched in a few seasons often need more than a basic sweep, which is why we price per job rather than quoting a flat number over the phone. Call (866) 596-7310 for an exact quote.
Chimney sweep prices vary in St. Louis because the job itself varies: flue size, how much creosote has built up, whether there's a liner, and whether the chimney is on an interior wall or an exterior one all change the work. A simple sweep on a well-maintained flue is one job. A flue packed with glazed creosote that needs a chemical treatment before sweeping is another. Roof access also matters, especially on the steep-pitched roofs common in older St. Louis neighborhoods. That's why we inspect first and quote in writing. Call (866) 596-7310 and we'll walk you through it.
Yes, the estimate is free. We don't charge a trip fee, a diagnostic fee or a dispatch fee. You get a written price for the work before anything is booked, and the final price is whatever that written estimate says. Nothing gets added for a second flue or a roof climb without your approval first. If you're comparing chimney companies in St. Louis, get the number in writing from each one so you're comparing the same scope of work. Call (866) 596-7310 for your free estimate.
Most buyers in St. Louis should get a level 2 chimney inspection during the buying process, because a standard home inspection rarely covers the inside of the flue. Older housing stock in neighborhoods like Tower Grove, Shaw and Benton Park often has clay tile liners that have cracked or shifted over decades of heating cycles. A camera inspection shows what the flue actually looks like, and you get a photo report you can hand to your agent. That's leverage in a negotiation. Call (866) 596-7310 to book one before closing.
Service & Process FAQs
A chimney sweep means we run a brush through the flue to remove creosote and soot, then vacuum the firebox and smoke chamber with a HEPA vacuum so nothing ends up in your living room. We lay drop cloths, seal the opening, and work from the roof and the firebox. After the sweep we run a camera down the flue and show you the footage. If we find cracks, gaps or heavy creosote glazing, you see it on screen rather than taking our word for it. That evidence is the whole point. Call (866) 596-7310 to book a sweep.
Most St. Louis homes burning wood should get a sweep once a year, and the same goes for anyone burning regularly through the heating season. Creosote builds up faster than people expect, and the cool, damp winters here mean a lot of fires run with damp wood, which produces more of it. Gas and oil flues still need an annual look even though there's no creosote, because liners and connections can fail quietly. It's a check, not a sales pitch. Call (866) 596-7310 to get on the schedule before burning season.
Creosote is the tar-like residue left behind when wood burns incompletely, and it's the main fuel source in a chimney fire. St. Louis winters are cold enough that fireplaces run hard for months, and if the wood is unseasoned or the fire is smoldered at low draft, creosote accumulates in a hurry. It starts as a flaky soot, turns crusty, then glazes into a hard, shiny layer that a standard brush won't remove. Glazed creosote is what we treat chemically before sweeping. If you're seeing shiny black deposits, don't burn until it's checked. Call (866) 596-7310.
A level 1 inspection is a visual check of accessible parts of the chimney during a routine sweep. A level 2 adds a camera run through the flue and is what you want after a chimney fire, a liner change, or a home purchase. A level 3 opens up concealed areas of the chimney when a level 2 finds a problem that can't be seen otherwise. Most St. Louis homeowners booking a routine sweep get a level 1, and we recommend level 2 when there's a reason. Call (866) 596-7310 and we'll tell you which one fits.
You can sweep a flue yourself if you have the right brushes, a proper vacuum and safe roof access, but the inspection is the part most homeowners can't do themselves. You can't see a hairline crack in a clay liner from the firebox, and you can't judge creosote glaze by look and feel. Roof work on steep pitches is genuinely dangerous, and St. Louis has plenty of steep pitches. That's the part worth handing to a trained professional. Call (866) 596-7310 to book a sweep with camera inspection.
Skipping a sweep leaves creosote in the flue, and creosote is what burns in a chimney fire. Beyond fire risk, a blocked or cracked flue can let carbon monoxide back into the house instead of up the chimney, which is the quieter hazard. Neither one announces itself. You can burn for years with a cracked liner and never know it. That's why we camera-inspect and show you the footage. If everything checks out, we tell you so and you can safely wait. Call (866) 596-7310 if it's been more than a season.
Brands & Parts FAQs
We work with names like HeatShield, Gelco and Olympia Chimney when a liner repair or resleeve is needed. HeatShield is a resurfacing product used to seal cracks in an existing clay liner, and Gelco and Olympia Chimney make stainless liners and related components. Which one fits depends on the flue you have and what the camera shows. We explain the options and the reason for each one before anything is ordered. Call (866) 596-7310 to talk through what your chimney needs.
You need a new liner only if the camera shows the existing one has failed: cracks you can see, gaps at the joints, or a flue that's the wrong size for the appliance. A lot of "you need a liner" recommendations happen without evidence, and we don't do that. If the clay liner is sound, we sweep and leave it alone. If it's cracked, resurfacing with a product like HeatShield is sometimes enough, and sometimes a stainless liner from Olympia Chimney or Gelco is the right fix. You see the footage first. Call (866) 596-7310 for a camera inspection.
A stainless liner is the better choice when the existing clay liner is badly cracked, spalling or the wrong size, because it creates a new continuous flue inside the old one. Resurfacing with HeatShield works well when the cracks are minor and the existing structure is otherwise sound. Both are legitimate repairs; the difference is what the camera shows. We don't upsell either one. The photo report tells you which situation you're in, and the written estimate covers the fix. Call (866) 596-7310 to see what your flue looks like.
Licensing & Insurance FAQs
Chimney sweeping isn't licensed at the state level in Missouri, so licensing is handled locally and through industry certification. Every pro working under our name is required to hold the license and insurance their state requires, and we ask for proof before anyone is connected to a homeowner. Ask any chimney company in St. Louis what certification their technicians carry and who insures the work. A real pro will answer without hesitation. Call (866) 596-7310 if you want to know what to ask.
Yes. Every pro working under our name is required to hold liability insurance, and we verify it. That matters more than people think: a technician on your roof or in your flue is doing physical work with real risk, and if something goes wrong, an insured professional is what protects you. We don't send anyone out who can't show coverage. If you're comparing chimney companies in St. Louis, ask for their insurance details before booking. It's a fair question. Call (866) 596-7310 with any questions.
Every pro working under our name is required to hold the license and insurance their state requires, and we confirm both before connecting them with a homeowner. Our technicians have up to 12 years of experience, which is the kind of background we look for. We don't send unvetted help. The work is done by independent local professionals who know the housing stock in this region, and we connect you with them. Call (866) 596-7310 if you want to know more about how that works.
Same-Day Service & Response FAQs
Same-day service is often possible in St. Louis, depending on the day and where you are. Call (866) 596-7310. We answer 24/7 and dispatch Sunday through Friday, 7am to 7pm. We're closed Saturday. If you call when dispatch has closed for the day, the call is answered and booked into the next opening. Chimney work isn't usually an emergency in the way a burst pipe is, but if you've had a chimney fire or smell smoke in the house, don't burn until someone looks at it. Call and we'll get you in as soon as we can.
A live coordinator answers and takes your details, then connects you with an independent local professional. We answer 24/7. Fast dispatch, 7am-7pm, Sunday through Friday, closed Saturday.

If you call outside dispatch hours, the call is still answered and booked into the next opening, so you're not left calling back. Call (866) 596-7310 when you're ready.
No. Same-day and urgent work is not priced higher. The price is set per job by the written estimate, and that estimate doesn't change because you called in the morning and needed help sooner. Urgency here is usually seasonal anyway, before burning season starts and the schedule fills. If you want to get ahead of that, book now instead of waiting. Estimates are free. Call (866) 596-7310 and we'll put a written price in front of you.
Warranty & Guarantees FAQs
Manufacturer warranties on stainless liners and resurfacing products like HeatShield and Olympia Chimney come from the maker, and the terms depend on the product installed. You'll see the warranty documentation in writing along with your estimate, before anything is installed. We don't promise a specific warranty length because it genuinely varies by product and application. What we stand behind is the work and the diagnosis: if the camera showed a problem, the fix addresses it. Call (866) 596-7310 to go over the details.
If the inspection finds nothing wrong, we tell you that and you can wait. You won't be sold a liner you don't need. The whole point of a camera inspection and photo report is that you can see for yourself, so if the flue is sound, the footage proves it. We'd rather tell you your chimney is fine than sell work you can verify you didn't need. Call (866) 596-7310 to book the inspection. Estimates are free.
