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 Glenmont Homeowners Choose Top Hat Chimney
Glenmont is the kind of place where people still ask their neighbors who they trust. Ask anyone on your street. The name that comes up is usually the same one that’s been working these blocks for decades.
Homes along Georgia Avenue, in the subdivisions around Glenmont Park, and back in the quiet streets off Randolph Road have a particular kind of chimney problem. We know these houses. We know that a split-level on one side of a Glenmont street often has the same flue dimensions, the same clay tile liner, and the same moisture issues as the split-level three doors down, because they were built in the same construction season by the same crew. When Wendell finds a failed damper on one property, he can often tell you what the next three neighbors are going to need. That’s not a guess. It’s 29 years of repetition.
Every call is answered by a live person, around the clock. It may well be Wendell himself. You get upfront pricing before a single tool comes off the truck, and the number you hear on the phone is the number on the invoice. Every job, no exceptions, comes with the 90-Day Done Right Promise in writing: if it’s not right, one call brings the crew back at no additional cost.
We serve the full Glenmont area, including the neighborhoods around Glenmont Park, Wheaton-Glenmont, the residential streets north of the Glenmont Metro station, and the subdivisions off Layhill Road.
Chimney Cleaning Services We Offer in Glenmont
Chimney Cleaning & Sweep
A sweep removes creosote, soot, and any debris that’s accumulated in your flue since the last burn season. For Glenmont’s older masonry chimneys, this is the first line of defense against chimney fires and slow-drafting smoke. Once a year, burn or no burn. Chimneys break in the off-season too.

Chimney Repair
Crumbling mortar joints, spalling brick, cracked crowns, and rusted dampers are common on Glenmont’s 50-to-70-year-old chimneys. Wendell and his crew repair what’s actually broken and tell you plainly when something can wait. No scare-selling. No invented emergencies.

Fireplace Services
From gas log installation to damper replacement to full fireplace rebuilds, we handle the firebox and everything that feeds it. Glenmont homes with original wood-burning fireplaces often have dampers that warped or seized decades ago. We’ll show you what’s happening on camera and then give you a straight answer about what it costs to fix.

Chimney Cap & Crown
A properly fitted cap keeps rain, birds, and squirrels out of your flue. The crown, that concrete slab at the very top of the chimney, is what sheds water. When it cracks, which it does on most Glenmont chimneys after enough freeze-thaw cycles, water seeps into the masonry and the trouble compounds. We install caps and rebuild crowns using materials made for this climate.

Chimney Liner & Rebuild
This is the big one in Glenmont, and it’s the thing most often recommended by national outfits over the phone without anyone ever looking at the chimney. We don’t recommend a liner unless the camera footage shows you exactly why it’s needed. When it is needed, we install liners from trusted brands like DuraFlex and HeatShield, and we warranty the work in writing.

Why Glenmont’s Climate & Housing Affect Chimney Cleaning
Glenmont’s residential fabric is overwhelmingly mid-century tract development. These homes were built during Montgomery County’s post-WWII boom, and they’re now at an age where the original chimneys are either failing or quietly on their way. The flues were sized to exhaust oil-fired furnaces, not today’s high-efficiency gas appliances. That matters more than most homeowners realize.
When a house converts from oil to gas, the chimney suddenly has a flue that’s far too large for the volume of exhaust the new appliance produces. The gases cool too quickly, condense on the clay tile walls, and create the perfect conditions for creosote accumulation and liner cracking. In Glenmont, where the conversion happened block by block over the past two decades, this problem is everywhere. Our work here involves far more relining than comparable neighborhoods in newer parts of western Montgomery County. It’s not that the chimneys were built badly. They were built for a different fuel source, and they’ve outlived their intended design.
The DC Metro freeze-thaw cycle doesn’t help. Winters here hover around 32°F, which means water seeps into hairline cracks, freezes, expands, and repeats the process dozens of times in a single season. Summer thunderstorms drive additional moisture into any gap in a crown or cap. For Glenmont’s single-wythe brick chimneys, made from softer mid-century brick, this cycle is relentless. It’s why we see spalling and mortar joint failure on nearly every chimney we inspect that hasn’t been maintained.
One more thing worth knowing about Glenmont specifically: in the platted subdivisions where dozens of nearly identical homes went up in the same construction season, chimneys age on an almost synchronized schedule. A failed damper found on one house often predicts the same issue three doors down. Wendell has seen it enough times to know when it’s a one-off and when it’s the start of a block-wide pattern.
Pricing for Chimney Cleaning in Glenmont

- Standard chimney cleaning and inspection: $189-$329 depending on flue size, accessibility, and how much creosote has built up.
- Chimney cap installation: $150-$450 including the cap and labor, depending on whether we need a custom fit for an odd-sized flue.
- Crown repair or rebuild: $350-$900 depending on the extent of cracking and whether the old crown needs full removal.

FAQs About Chimney Cleaning in Glenmont
Expect $189 to $329 for a standard cleaning and inspection. The price depends on how much creosote has built up, how tall the chimney is, and whether the flue has any obstacles. We quote flat prices before the work starts, and the price on the phone is the price on the invoice. Call (240) 618-3233 for an exact quote, free.
Once a year, even if you only burn a few fires each season. Glenmont’s converted oil-to-gas chimneys can accumulate creosote even when you think you’re barely using the fireplace. Annual sweeping also gives Wendell a chance to catch small crown cracks and damper issues before they turn into liner replacement jobs. It’s cheaper to sweep than to rebuild.
Maybe. Maybe not. We won’t recommend a liner unless the camera footage shows you exactly why it’s needed, crack by crack. If you got a liner recommendation from a national company that never put a camera up the flue, ask us for a free second opinion. We’ve told plenty of Glenmont homeowners their liner can safely wait. Other times, the footage shows the clay tiles have separated and it’s a hazard that needs addressing before the next burn season. The difference is evidence, and we’ll hand it to you either way.
First-degree creosote is a brush job. Third-degree is a glaze. The difference is time. Skipped cleanings let creosote harden into a tar-like coating that’s harder to remove and more combustible. In a chimney that’s already oversized for a gas appliance, you’re also looking at acidic condensation eating away at the clay liner. A chimney fire is the worst case. A $6,000 liner replacement is the more common one. A $250 annual sweep prevents both.
Freeze-thaw cycling. Glenmont winters bounce above and below freezing constantly, and every time water in a hairline crack freezes, it expands and widens the crack slightly. Over thirty or forty freeze-thaw events in a single winter, a small crack becomes a visible gap. By spring, water has worked into the brick and mortar, and your chimney starts spalling or leaking. It’s not the rain. It’s the temperature swings. Call (240) 618-3233 and we’ll take a look before the next cycle starts.

What Glenmont Customers Say
"Converted our old wood burner to gas and took the time to talk me out of the fancier insert I had picked out because it would have been wrong for the size of the room."
- Duane Kittering"Creosote build up was bad enough that he showed me a jar of it. Explained the difference between the stages and why the wood I had been burning was the cause. I have burned seasoned wood ever since."
- Gordon Selkirk"Turns up in the hat, which the children thought was the best thing that had ever happened, and left the hearth cleaner than he found it."
- Josefina Aranda
