Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterTrusted Chimney Cleaning & Sweep for Bethesda Homeowners
A chimney sweep in Bethesda typically costs $220 to $390 for a standard cleaning with a Level 1 Inspection, and most jobs are finished in 90 minutes or less from the time Wendell and his crew arrive at your door. If it has been more than a year since your last sweep, or if you have recently moved into an older home around Bradley Hills or Edgemoor, the creosote in your flue has had time to build up, and that is exactly what we come out to fix.
Top Hat Chimney has been cleaning and inspecting Bethesda chimneys since 1999, which means we have been doing this long enough to have swept the same flue for two generations of the same family. Wendell Pike puts his name and license number on every job, and the crew that shows up is background-checked, uniformed, and paid to do the job right, not to sell you a liner you do not need. Call (240) 618-3233 for upfront pricing before a single tool comes off the truck.
What Our Chimney Cleaning & Sweep Service Includes
Every chimney is different, but the guts of the job stay the same: remove what has built up, check what has worn out, and tell you plainly what needs doing now and what can wait. We never leave without camera evidence of the work and a plain-English verdict on what we found.
Level 1 Inspection
A Level 1 inspection is the standard check we run during every routine sweep. We look at the accessible portions of the flue, the firebox, the damper, and the exterior masonry to confirm nothing has shifted or cracked since your last cleaning. If your chimney has been used the same way year after year and nothing has changed, a Level 1 inspection is typically all you need. Wendell documents what he sees with a camera and tells you whether the chimney is safe to burn.
Level 2 Inspection
A Level 2 inspection goes further and is the one you want when something has changed: a new stove, a new liner, a chimney fire, a lightning strike, or a house you just bought. We run a camera the full length of the flue and inspect the attic, crawlspace, and any accessible chase areas. In Bethesda, where many homes date to the 1930s and 1940s, we regularly find hidden damage in old clay tile liners that a quick look would miss. We include the footage with the report so you can see the problem yourself.
Creosote Removal
Creosote is the black or brown residue your fires leave behind, and it is the reason chimneys catch fire if they are not swept. First-degree creosote is a brush job; third-degree is a glaze that hardens into a shiny tar and takes rotary tools and patience. Bethesda winters mean a lot of slow, smoldering fires in older masonry fireplaces, and smoldering fires produce creosote faster than anything else. Our Creosote Removal service takes care of what is there, and we tell you how to slow down the buildup between visits.
Soot Removal
Soot is powdery and easy to remove compared to creosote, but it still blocks airflow and blackens your firebox and glass doors. We vacuum and brush it from the flue, smoke chamber, and firebox, and we lay drop cloths from the driveway to the hearth so the job does not track through your living room. If your fireplace has glass doors, we clean the interior glass as part of the sweep. You should not be looking at last winter’s soot every time you light a fire.
Annual Sweep
The National Fire Protection Association recommends a chimney cleaning once a year, burn or no burn. Chimneys break in the off-season too: water gets into masonry, animals build nests, and damp creosote turns acidic and eats at metal liners. We put Bethesda homeowners on an Annual Sweep schedule so you do not have to remember, and we call you when it is time. A yearly sweep takes about an hour and catches problems when they are still small.
Fireplace Cleaning
Fireplace Cleaning covers what you see and what you do not: the firebox floor, the damper, the smoke shelf, and the glass doors. We remove ash and debris, inspect the firebrick for cracks, and make sure the damper opens and closes the way it should. If your fireplace smells in the summer when it is humid, the cause is usually creosote and soot sitting in the smoke chamber, and a proper cleaning fixes it. Wendell also checks that your grate sits at the right height and your logs have clearance from the walls.

Brands We Service for Chimney Cleaning & Sweep
Wendell has been installing and servicing DuraFlex liners for years, and most of the stainless-steel relining jobs around Bethesda come out of a DuraFlex kit. The product is straightforward, the parts are available, and we know the sizing and installation quirks cold. If you have a DuraFlex liner in need of a sweep, we clean it the same way we clean any other stainless liner: poly brushes and low-speed rotary tools that will not scratch the corrugated walls.
We also work on systems built with Copperfield and Famco components, including caps, dampers, and chase covers. Those are the brands we reach for when a Bethesda homeowner needs a new cap after a squirrel has gotten in, because the hardware is solid and the warranty is honest. Whether you have a DuraFlex, Copperfield, or Famco system, or a 60-year-old clay tile flue with no name on it at all, we can service it. A chimney is a chimney; what matters is that it draws and it is clean.
Signs You Need Chimney Cleaning & Sweep Right Now
- Your living room smells like a campfire when the fireplace is not lit. That smell is creosote and soot sitting in the smoke chamber, especially on humid Bethesda afternoons. It means the buildup is thick enough to off-gas into the house, and it is time to get it out before the next fire.
- Smoke rolls back into the room when you open the door or light a fire. Poor draft usually has a physical cause: a choked flue, a cold chimney, or a damper that is not fully open. We find the cause instead of guessing at it, and often the fix is as simple as a good cleaning.
- You can see dark, shiny buildup on the damper or reach up and feel it. If you can touch creosote inside your firebox, it is already past the first-degree stage. The shiny glaze is third-degree creosote, and it burns hot and fast once it ignites. Do not try to scrape it yourself; creosote removal is a job for someone who does it weekly.
- Birds, squirrels, or bugs have been in or near the chimney. Animals nest in flues every spring in Bethesda, and a nest is a fuel blockage waiting for a lit match. We remove the nest and inspect for any damage the animal did on the way in, then talk about a cap to keep it from happening again.
- It has been more than a year since your last sweep, and you cannot remember if you ever had one. Most chimney fires in Montgomery County happen in flues that had not been cleaned in years. Once a year, burn or no burn, is the cheapest fire insurance you will ever buy.
Our Chimney Cleaning & Sweep Process - Step by Step
We do not do surprises. Here is how a typical sweep goes when you call Top Hat Chimney in Bethesda.
- 1
You call and talk to a person. A live person answers the phone around the clock, and it may well be Wendell himself. You describe what is going on with your chimney, and we give you a flat price for the sweep over the phone. That number is the number on the invoice.
- 2
We show up in uniform, with a real arrival window. The crew arrives in a company truck, in uniform, with the equipment laid out and drop cloths down before we open a flue. If traffic on the Beltway slows us down, we call you. You will not be left waiting and wondering.
- 3
We sweep the flue top to bottom. We brush from the top down and vacuum from the bottom up, then clean the smoke chamber, smoke shelf, damper, and firebox. Every sweep includes the full cleaning, not just a quick pass with a brush.
- 4
We run the camera and show you the footage. Before we leave, we run a camera up the flue and walk you through what we see. If we find a cracked tile, a rusted liner, or a separated flue, you will see it with your own eyes. The camera footage and a plain-English verdict, every time, no exceptions.
- 5
We leave you with a written report and a clean hearth. You get a report that states what we did, what we saw, and what we recommend for next time. If anything needs repair, we give you a written estimate and leave it at that. No pressure, no scare tactics, no work done you did not approve.
How Much Does Chimney Cleaning & Sweep Cost in Bethesda?
A standard chimney cleaning and Level 1 inspection in Bethesda runs $220 to $390 for most single-flue masonry fireplaces. If you have a wood stove or insert, the price may be slightly higher due to the extra disassembly. If we find creosote glaze or an animal nest during the job, removal takes longer and the price adjusts accordingly, but we will tell you before we do the extra work, not after.
Three things affect the price most: the height of the chimney, the amount of buildup, and whether the flue has an insert or liner that needs special care. The way to avoid overpaying is simple: get your sweep done yearly so the buildup never gets out of control, and ask for a flat price before the appointment. We give you the price over the phone, and we honor it. Our free estimate includes the camera inspection and the full written report, whether you hire us for the sweep or not. Call (240) 618-3233 for an exact quote on your chimney.

Frequently Asked Questions - Chimney Cleaning & Sweep in Bethesda
Chimney cleaning and sweep means removing creosote, soot, and debris from the inside of your chimney flue so smoke can escape safely and the buildup cannot catch fire. We brush the full length of the flue, vacuum the firebox and smoke chamber, and inspect the system for cracks, blockages, or damage. The goal is a chimney that draws properly and is safe to use all winter.
A routine chimney sweep and inspection takes 60 to 90 minutes from setup to final walkthrough. If we find heavy creosote glaze, an animal nest, or an insert that needs to come out, the job can run two hours or more. We tell you before we start whether your chimney looks like a standard job or something that will take longer.
Most standard chimney sweeps in Bethesda cost between $220 and $390 for a single-flue fireplace. Wood stoves, inserts, steep roofs, and heavy creosote can raise the price, but we give you a flat number on the phone before the truck leaves our yard. Call (240) 618-3233 for a free, no-obligation quote.
Yes. Wendell has installed and swept DuraFlex stainless steel liners for years, and we know how to clean them without scratching or damaging the corrugated interior. If your liner is older and showing rust or separation, the camera will show it, and we will tell you honestly whether it can be saved or needs replacement.
We book sweeps six days a week, and we keep evening slots open for homeowners who work during the day. Bethesda homeowners call us on Saturday mornings all winter long, and we try hard to get to you before your next fire. The phone is answered by a live person around the clock, so call whenever the issue is on your mind.
Every job we complete is backed by our 90-Day Done Right Promise: if the sweep or inspection was not done right, one call brings Wendell back to make it right at no additional cost. The promise is in writing, on every single job, and it has been for years. We also honor senior and veteran discounts of 10 percent on every job, always.
Clear the area around the fireplace by moving furniture, rugs, and anything breakable away from the hearth, and avoid using the fireplace for 24 hours before we arrive so everything is cool. Leave the damper closed until we open it ourselves. We bring the drop cloths, the vacuum, and the tools, and we leave the room as clean as we found it.
