Frequently Asked Questions

Chimney and Dryer Vent Questions, Answered Straight

Most of what people ask us comes down to cost, timing, and whether the work is worth doing now or can wait a season. This page collects the questions we hear most on the phone and at the door, with the same answers we’d give you standing in your living room. If you’re looking for the full picture of how we work, start with our home page or go straight to Chimney Sweep in Downey.

Key Takeaways

• Chimney sweeping is priced by the system, not the hour – a standard sweep and inspection is one rate, and added appliances, blockages, or heavy creosote change it.
• We sweep it, we inspect it, and we repair it: chimney repair and dryer vent cleaning run under the same roof as sweeping.
• We only stock trade-spec materials – DuraFlex liners, HeatShield ceramic resurfacer, Gelco, Olympia Chimney, Famco, and Copperfield – because hardware-store substitutes don’t hold up to flue conditions.
• Every visit starts with an honest assessment. If your chimney doesn’t need work, we’ll tell you that and go.

Pricing & Estimates

How much does chimney cleaning service cost?

A standard chimney sweep with a Level 1 inspection typically runs $150 to $350 for one flue, and the price moves with the condition of the system rather than the clock. A fireplace that’s burned a cord or two a season sits at the low end. Add a wood insert, a second appliance on the same chimney, heavy creosote, or an animal nest and the job takes longer and costs more. We quote before we start, so you’re never looking at a number you didn’t agree to. Call (866) 253-8489 for an exact quote on your chimney – estimates are free.

Do you offer free estimates?

Yes. Estimates on repair work are free, and a sweep quote over the phone or by photo costs you nothing. If the chimney needs a liner, a crown rebuild, or resurfacing, we’ll walk the flue, show you what we found, and put the numbers in writing before any material is ordered. The only charge that shows up on your invoice is the work you approved.

Is it cheaper to repair my chimney or replace the liner?

Repair is often the cheaper path, and with HeatShield ceramic resurfacing it’s available more often than most homeowners expect. HeatShield smooths and restores deteriorated flue tiles from the inside, which means a chimney with cracked or spalling tiles in qualifying condition can be brought back to service without a full liner replacement. When the flue is too far gone – offset tiles, missing mortar joints through the wall, an undersized flue for the appliance – a DuraFlex liner is the right call and we’ll say so plainly. We quote both paths when both are real options and let you decide.

What payment methods do you accept?

We take standard payment methods including major credit cards, debit cards, and checks. Payment is collected after the work is done and you’ve had a chance to look it over, not before we climb on the roof. If your job involves a repair, we’ll confirm the total against the written estimate before we start.

Service & Scheduling

Do you offer emergency chimney cleaning service?

We prioritize urgent calls – a chimney that’s smoking into the house, a blocked flue, a bird or raccoon in the chimney, or a dryer vent that’s stopped moving air. Those situations get moved to the front of the schedule. If you smell smoke indoors with no fire burning, or your carbon monoxide alarm has gone off, leave the house and call 911 first, then call us at (866) 253-8489. A blocked flue is a genuine hazard, not a nuisance, and it needs a trained set of eyes before anyone lights another fire.

How fast can you respond?

Most calls get a same-week appointment, and urgent safety calls move faster than that. Response time depends on the season – fall and early winter are our busiest weeks because everyone schedules at once – so if you’re calling in October with a dirty flue, book early. Spring and summer appointments are the easiest to place and the best time to catch small issues before they become repairs.

How often should a chimney be swept?

Once a year is the standard, and it holds for most wood-burning fireplaces regardless of how often you burn. The reason is inspection as much as cleaning: a yearly sweep is also the annual look at the flue, cap, crown, and damper, which is where we catch cracks, loose mortar, and rusted caps before they turn into water damage. Gas appliances and wood inserts should be checked on the same yearly rhythm. If you burn a lot of softwood or green wood, you may need a mid-season cleaning on top of the annual visit.

What actually happens during a chimney sweep?

A sweep removes creosote, soot, and blockages from the flue, then inspects the system from firebox to cap. Here’s the sequence we follow on a standard visit:

1. Lay drop cloths and set up a sealed vacuum so no soot reaches your floors or air.
2. Brush the flue with the correct-sized brush for your liner type – clay tile, stainless, or masonry.
3. Clean the firebox, smoke shelf, and damper area, and pull any debris from the firebox floor.
4. Inspect the flue interior, cap, crown, flashing, and damper, and check clearances at the roofline.
5. Photograph anything worth showing you – cracks, glaze, rust, a failing crown – and walk you through it before we leave.
6. Recommend repair only for what actually needs it, with a written estimate if you want the work quoted.

We do not sweep a chimney and then hand you a list of upsells. If the flue is sound, we tell you that and you’ll see us next year.

Can you sweep and repair on the same visit?

Yes, in many cases. One of the practical advantages of running sweeping and repair under one roof is that when we find a cracked crown, a missing cap, or a damaged damper during the sweep, we already have the material on the truck or can schedule the fix without you calling a second contractor. Some repairs – a liner install, a crown rebuild, resurfacing with HeatShield – need their own appointment because they take longer and use materials ordered to your flue’s measurements. Either way, you’re dealing with one company from the first phone call to the last invoice.

How long does a chimney sweep take?

A single-flue sweep typically takes 45 minutes to 90 minutes. Add time for a second appliance on the same chimney, a heavy creosote load, or a blockage that needs to be broken up and removed. A dryer vent cleaning usually runs 45 minutes to an hour on its own. If we’re doing both in one visit, plan on about two hours.

Licensing, Trust & Guarantees

Are you licensed and insured?

Yes. Brownstone Chimney Sweep is a licensed and insured chimney and vent company, and we’re happy to provide documentation on request. We think that matters more in this trade than in most, because we’re working on a fire system and often on your roof. You should never let an uninsured, unlicensed sweep climb your chimney and start pulling tiles – if something goes wrong, the liability lands on you, not them.

Do you guarantee your work?

Yes. Our workmanship is guaranteed, and if something we installed or repaired doesn’t perform the way it should, we come back and make it right. Material warranties follow the manufacturer – DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield all stand behind their products – and we walk you through what’s covered by whom when the job is done. We keep records of every install so we can support you years later.

What brands and materials do you use?

We use DuraFlex liners, HeatShield ceramic resurfacer, Gelco, Olympia Chimney, Famco, and Copperfield – the same product lines professional chimney technicians specify. The reason comes down to how these materials behave in a real flue: a DuraFlex liner is sized and installed for the appliance it serves, whether that’s wood, gas, or oil, so you don’t get a one-size-fits-all drop-in. HeatShield is a ceramic-based resurfacer designed to restore tile rather than disguise damage. Famco ventilation products cover caps, dampers, and terminations that actually seal. These are the parts a chimney sees for twenty years, and cheap substitutes are exactly the parts that fail early.

Do you only do chimney work, or are you a general contractor?

We’re a chimney and vent specialist, not a generalist. Our work falls into three lines: chimney sweeping, chimney repair, and dryer vent cleaning. We don’t take on roofing, HVAC, or general masonry contracting – if your issue is outside those three, we’ll tell you and point you toward the right trade. That focus is deliberate. Chimney systems behave differently than any other part of a house, and it takes a specialist to read one accurately.

Specific Services

Do you handle chimney cleaning and sweeping?

Yes. Chimney sweeping is our core service – cleaning creosote and soot from wood-burning fireplaces, wood inserts, and gas appliances, plus the fireplace opening, smoke chamber, and damper area. We sweep by flue, not by guesswork, and we tailor the brush and technique to your liner material. If your chimney hasn’t been swept in three or more years, expect a longer job; glaze creosote, the hard shiny stage, needs extra attention because it’s the stage most likely to fuel a chimney fire. Find the full details on our Chimney Sweep in Downey page.

Do you handle chimney repair?

Yes. Chimney repair covers a range of work that comes up during a sweep or shows up on a roof inspection – cracked and spalling flue tiles, missing mortar joints, damaged dampers, leaking crowns, loose flashing, and failing caps. We also install liners, resurface flues with HeatShield, and rebuild crowns. Repair is where using spec-grade materials pays off. A crown patched with caulk and a coat of paint will look fine for a winter and then crack again with the first hard freeze. A crown rebuilt to shed water away from the flue lasts.

Do you handle fireplace services?

Yes. Fireplace work covers sweeping, firebox cleaning, damper inspection and repair, cap and screen replacement, and liner work for wood-burning inserts. We also inspect gas fireplaces and gas logs, checking that the flue is properly sized and clear for the appliance – an area where a lot of dangerous installations happen because someone dropped gas logs into a fireplace built for wood. If your fireplace smokes into the room, has trouble drafting, or you’re hearing a whistle or rattle on windy days, that’s worth a look.

Do you handle chimney cap and crown work?

Yes. Caps and crowns take years of weather – rain, sun, freeze-thaw cycles, and the occasional bird – and both fail quietly. A missing or loose chimney cap lets water, animals, and leaves straight into the flue, and the cap is the first line of defense. A cracked crown lets water soak into the masonry and work its way down, which is how a chimney ends up needing major repair years later. We install caps and rebuild crowns using Famco ventilation products and proper masonry methods, not a hardware-store cap sealed in place with whatever caulk was on the shelf.

Do you handle dryer vent cleaning?

Yes. Dryer vent cleaning is one of our core services, and it uses the same fire-safety thinking we bring to chimneys. Lint builds up in the ductwork and the exterior termination, restricts airflow, and can ignite from the heat of the dryer itself – which is why dryer fires are more common than most homeowners realize. We clean the full run, clear the exterior vent, check the transition duct, and test the airflow so you can see the difference. If the duct is crushed behind the dryer or runs too long for the machine, we’ll flag that too, because a clogged dryer vent isn’t fixed by cleaning alone.

Do you handle light commercial properties?

Yes, on a case-by-case basis. We default to residential work, but we do take on light commercial chimney and vent jobs where the system is similar to what we see in homes. Call us with the details and we’ll tell you honestly if it’s within our scope or whether you need a different trade.

Working with Us

How do I know if my chimney needs a repair, not just a sweep?

A chimney needs repair, not just a sweep, when a sweep turns up structural or safety problems – cracked flue tiles, missing mortar, a rusted or loose cap, a crown with visible cracks, water staining inside the firebox, or debris falling into the firebox. Water is behind a surprising share of chimney repairs, which is why the crown, cap, and flashing get as much of our attention as the flue interior. If we find anything, we photograph it and show you. We never push repair work you don’t need.

What should I do if smoke comes into my house?

Stop using the fireplace and call for an inspection. Smoke spilling into the room means the draft is compromised – a blocked flue, a closed or stuck damper, a cold chimney, or a flue that’s undersized for the fireplace opening. Don’t relight it to “test” whether it’s resolved. A blocked flue can push carbon monoxide into the living space, so this is a situation for a trained inspection, not a wait-and-see. Call us and we’ll get eyes on it.

Can you come out for a chimney inspection even if I don’t need a cleaning?

Yes. We do standalone inspections, and they’re a good idea if you’ve recently bought a house, are about to buy one, or are selling and need documentation. The inspection covers the same ground we’d look at during a sweep – flue interior, cap, crown, damper, clearances – without the cleaning charge. If it turns out the flue does need sweeping, we can usually take care of it that day.

Do you work on gas-burning appliances?

Yes. Gas logs, gas fireplaces, and gas inserts all get inspected as part of our fireplace service, and a gas appliance on a chimney gets swept and checked on the same yearly schedule. One point worth repeating: a gas appliance produces far less creosote than wood, but it still needs a clear, properly sized flue. We verify the flue is right for the appliance before you use it.

If you didn’t find your question here, the fastest answer is a phone call. We’ll ask a few questions about your chimney or your dryer vent, tell you what to expect, and quote it before we schedule. Call Brownstone Chimney Sweep at (866) 253-8489 for a free estimate. We sweep it, we inspect it, we repair it – and we’ll tell you the truth about what your chimney actually needs.
