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.

Why Top Hat Chimney Is Glenmont’s Preferred Chimney Cleaning & Sweep Company
Wendell started Top Hat Chimney in 1999, and he’s been in and out of Glenmont homes ever since. Walk down any street off Randolph Road or Glenallan Avenue and ask who sweeps the neighborhood chimneys. You’ll hear his name. He puts his license number on every invoice, he shows up in uniform with a real arrival window, and if the work isn’t right, the 90-Day Done Right Promise means one call brings him back at no charge. That promise is in writing on every single job.
Glenmont homeowners tend to be skeptical of chimney companies, and we don’t blame them. The national outfits send a stranger who quotes one number on the phone and another at the door. That doesn’t happen here. The price you hear on the phone is the price on the invoice, before a single tool comes off the truck. And when you call, you get a live person. Sometimes it’s Wendell himself answering at 2 a.m. when you remember you never got the flue checked before burning season.
Our Chimney Cleaning & Sweep Services in Glenmont
Every sweep in Glenmont starts with the same promise: you’ll see the camera footage yourself, and you’ll get a plain-English verdict before any recommendation is made. No exceptions. If the flue is clean, we’ll tell you it’s clean and leave it alone. Here’s what we do most often for Glenmont homes.
Level 1 Inspection
A Level 1 inspection is the standard visual check we perform during every routine sweep in Glenmont. We look at the accessible portions of the fireplace, chimney exterior, and flue interior using a camera. Most Glenmont homes with regularly used fireplaces need this once a year, and it’s included with your cleaning.
Level 2 Inspection
This is the inspection Glenmont homes actually need, and it’s the one we emphasize most here. A Level 2 inspection includes everything in Level 1 plus a full video scan of the flue interior, the smoke chamber, and the attic and crawlspace portions of the chimney. Given the dual-flue architecture in so many Glenmont split-levels and Cape Cods, we recommend a Level 2 any time a home changes hands, after any chimney fire, or when an oil furnace has been converted to gas and the old flue was abandoned. More on that below.
Creosote Removal
Creosote forms every time wood burns, and Glenmont’s mid-century fireplaces accumulate it steadily. First-degree creosote is a brush job. Third-degree is a glaze that a brush cannot remove, and we’ll show you the difference on camera before we talk about anything else. Our Chimney Cleaning & Sweep team handles everything from light soot to hardened glaze, using rotary tools and chemical treatments where the deposits call for it.
Soot Removal
Soot is the fluffy black stuff that builds up fast and gets everywhere. In Glenmont fireplaces that get used heavily from November through March, we see enough soot accumulation to warrant a sweep every year, burn or no burn in the off-season. We vacuum as we go, run a HEPA filter, and leave the hearth cleaner than we found it. No dust cloud in your living room.

Common Chimney Cleaning & Sweep Problems We See in Glenmont Homes
- Abandoned furnace flues packed with debris. Glenmont’s 1950s and 1960s split-levels often had an oil furnace vented through the same masonry chimney as the fireplace. When those furnaces were converted to gas, the old flue was capped at the firebox and forgotten. Inside, we routinely find bird nests, collapsed terra cotta tile fragments, and standing water.
- Freeze-thaw damage to original mortar joints. Montgomery County winters cross 32°F repeatedly, and every freeze cycle widens the cracks in 60-year-old brick and mortar. Spalling brick faces and crumbling crown mortar are the rule on Glenmont chimneys, not the exception.
- Third-degree creosote glaze that a brush can’t touch. Homes that burned slow, smoldering fires for decades often have a hard, shiny creosote glaze inside the flue. A standard brush sweep won’t remove it, and any company that says the flue is clean afterward is not being straight with you.
- Unlined or damaged terra cotta flues. Nearly every original Glenmont chimney has terra cotta clay tile liners, and after 50 to 75 years, those tiles crack and separate. The camera footage shows it plainly. We’ve seen liners so compromised that the only safe fix is a proper stainless liner, and we’ll show you exactly why before recommending it.

FAQs - Chimney Cleaning & Sweep in Glenmont
Because the fireplace flue is only half the story. Glenmont’s split-levels built in the 1950s and 1960s often have a second flue in the same brick chase that originally vented an oil furnace. When the furnace went gas, that flue was capped and forgotten. A Level 2 inspection scopes both flues, and in Glenmont we regularly find the abandoned one packed with debris, cracked tiles, or standing water that can compromise the active fireplace flue without any visible warning. Call (240) 716-5865 to schedule one before burning season.
It means a standard sweep of the fireplace flue is not enough. On many Glenmont homes, the old oil-furnace flue shares a brick chase with the fireplace flue. Debris and moisture in the abandoned flue can migrate into the common masonry, damaging the flue you actually use. A proper Glenmont sweep includes checking both flues and capping any abandoned one that’s open to rain and animals.
Third-degree creosote is a hard, shiny glaze that forms when flue temperatures stay low and combustion is incomplete. It’s highly flammable and cannot be removed with a standard brush. Glenmont homes with decades of slow-burning fires often have it. We remove it with rotary tools and chemical treatments, and we’ll show you the before and after on camera so you know the flue is actually clean. For an exact quote on creosote removal, call (240) 716-5865.
Every time water seeps into a hairline crack and freezes, the ice expands and widens the crack slightly. Montgomery County’s winters cross 32°F dozens of times each season, so a 60-year-old Glenmont chimney takes a beating every winter. The result is spalling brick, crumbling mortar joints, and cracked crowns that let more water in each year. An annual inspection catches this early, before a small repoint becomes a full rebuild.
Yes, and you should. An open damper means rain, birds, squirrels, and humid Montgomery County air have been getting into that flue for years. We’ve swept Glenmont flues that hadn’t seen a fire in a decade and pulled out nests, leaves, and standing water. The sweep includes a camera inspection to make sure the flue tiles haven’t cracked during the idle years. Call (240) 716-5865 and we’ll get it sorted before you light the first fire.
How We Handle Glenmont’s Abandoned Dual-Flue Chimneys
This is where Glenmont is different from almost every other Montgomery County town, and it’s the reason we push Level 2 inspections so hard here. Along the Georgia Avenue corridor and the side streets off Layhill Road, thousands of homes went up between 1948 and 1975 with a single brick chimney housing two flues. One served the fireplace. The other served an oil-fired furnace in the basement. When natural gas lines came through, the oil tank came out, a high-efficiency furnace went in, and the old furnace flue was simply capped at the firebox and left inside the chase.
Nobody thinks about that abandoned flue until something goes wrong. But in Glenmont, we see the consequences on a regular basis. Bird nests, squirrel debris, collapsed terra cotta tile sections, and standing water sitting inside the unused flue. The problem is that the abandoned flue shares a brick chase with the fireplace flue you’re still using. Water pooling at the firebox level of the abandoned flue seeps into the common masonry, softens the mortar, and accelerates spalling that eventually compromises the entire chimney structure. The active fireplace flue looks fine from the inside. But the chimney itself is being damaged from the unused side.
On a split-level off Georgia Avenue, our crew recently swept a fireplace flue and found heavy second-degree creosote in the smoke chamber. That’s a straightforward cleaning job. But during the Level 2 inspection, we scoped the adjacent abandoned oil-furnace flue and discovered it packed with a bird nest and collapsed clay-tile fragments, with water pooling at the firebox level. We removed the debris, verified the shared brick chase was intact, and installed a proper cap on the abandoned flue so the active fireplace flue stayed protected. The homeowner had no idea any of this was happening. The fireplace worked fine. But the chimney was quietly taking on water, and another few years would have meant a much bigger repair.
So here’s our rule for Glenmont: if your home was built before 1975 and you don’t know what happened to the old furnace flue, we check it. Every time. The camera goes in, the footage comes out, and you watch it with us. Nothing gets recommended that you can’t see with your own eyes. That’s the only way to sweep a Glenmont chimney honestly.
