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.

We’ve been working the Prince George’s County chimney trade long enough to know the difference between a house on Livingston Road and one down by the Beltway interchange. Glassmanor’s particular story is written in its brickwork. This community went up fast after World War II, block after block of modest Cape Cods and ramblers thrown together for federal workers and young families pouring out of the District. The chimneys went up just as fast, most with clay-tile liners sized for coal or oil burners that roared at 150,000 BTU. Then the conversions came. Natural gas arrived, furnaces shrank to 60,000 BTU, and those oversized flues started weeping acidic condensate into mortar joints that were never designed for it. We’ve pulled apart enough Glassmanor fireboxes to know the pattern by heart. The homeowner bought the place in 1987 or 2003, never thought to ask what fuel it originally burned, and has no idea the liner is slowly digesting itself from the inside out. That’s the chimney we’re looking for when we drive into Glassmanor, and it’s why we bring a camera to every job.

Why Glassmanor Homeowners Choose Hearthstone Chimney Co.
Our company was founded in 1984, and we’ve spent more than four decades building a reputation one brick at a time. Glassmanor residents find us the same way most of our customers do - a neighbor mentions the name, or they remember our truck from a job on Owens Road. We’re not a chain operation cycling through technicians, and we’re not a one-truck outfit that might answer the phone this year and vanish the next. We plan to be sweeping chimneys in Prince George’s County thirty years from now, and we act accordingly.
Every technician we send to Glassmanor is background-checked, uniformed, and trained to work with the specific materials we trust: DuraFlex stainless liners, HeatShield cerfractory resurfacing, and Olympia Chimney components. Most jobs finish in a single visit. The price we quote upfront is the price on the invoice - no surprises, no “while we were in there” add-ons. And every call to (301) 479-9806 reaches a live person, 24 hours a day, seven days a week. Not a voicemail tree. Not a callback queue. A human being who can schedule your appointment or answer a question about what that sulfur smell in your firebox might mean.
We serve homes throughout Glassmanor, from the original postwar sections near the old Queen’s Chapel Road corridor to the pockets of later construction closer to the District line. Wherever you are in 20745, we know the housing stock and we’ve likely worked on a chimney very similar to yours.
Chimney Cleaning Services We Offer in Glassmanor
Chimney Cleaning & Sweep
Our standard sweep removes creosote buildup, bird nests, and debris from the flue using professional-grade brushes and HEPA-contained vacuums. For Glassmanor’s older masonry chimneys, we pay particular attention to the condition of the clay-tile liner and the amount of condensate staining at the flue base - both warning signs of an oversized liner serving an undersized appliance. Learn more about our Chimney Cleaning & Sweep in Glassmanor.
Chimney Repair
We rebuild spalling crowns, repoint deteriorated mortar joints, and address water infiltration that the humid Glassmanor summers and freeze-thaw winters accelerate. Every repair recommendation comes with photos you can see and a plain-English verdict on what needs doing now versus what can wait. Learn more about our Chimney Repair in Glassmanor.
Fireplace Services
From damper adjustment and smoke-chamber parging to firebox refractory panel replacement, we restore the safe function of wood-burning and gas fireplaces in Glassmanor’s vintage housing stock. We document the condition of every component with camera evidence before recommending any work. Learn more about our Fireplace Services in Glassmanor.
Chimney Cap & Crown Installation
A proper cap and a sound crown are the only defense against water entering the flue year-round. In Glassmanor, where north-facing chimneys grow moss and efflorescence from the humid summers, this protection is particularly critical. We fabricate and install caps using Gelco and Famco components sized to your specific flue.
Chimney Liner & Rebuild
This is the service we end up discussing on most Glassmanor jobs. When the original clay-tile liner is cracked, undersized for the current appliance, or deteriorated from decades of condensate exposure, we install a new stainless steel liner - typically DuraFlex - or rebuild the flue entirely. The work is governed by our 90-Day Done Right Promise: in writing, no arguing.
Neighborhoods We Serve in Glassmanor
Our crews know the streets and the chimney types that come with them. These are the Glassmanor neighborhoods where you’ll most often see our trucks:
- Livingston Road corridor - original 1950s ramblers with single-flue masonry chimneys, many still on original liners
- Owens Road area - denser postwar blocks where we’ve replaced multiple liners on the same street
- Queen’s Chapel Road vicinity - mixed vintage housing with varied chimney conditions depending on conversion history
- Beltway-adjacent sections - slightly later construction, but still carrying the same clay-tile legacy
Most Glassmanor appointments are scheduled within a week during the fall rush, sooner in spring and summer. Call (301) 479-9806 to check current availability.
Why Glassmanor’s Climate & Housing Affect Chimney Cleaning
Glassmanor sits on the DC Metro fringe, close enough to the District to feel urban pressure but far enough to have developed as genuine postwar suburbia. That location creates a specific weather pattern: 20 to 40 freeze-thaw cycles every winter, temperatures bouncing above and below freezing enough to stress mortar joints without ever locking into the sustained deep cold that would make catastrophic damage obvious. A chimney crown in Minneapolis cracks spectacularly and gets noticed. A chimney crown in Glassmanor develops hairline fractures that let water in slowly, year after year, until the freeze-thaw work has undermined the entire structure.
The summers compound the problem. Prince George’s County humidity settles on north-facing brick, promoting moss growth and efflorescence - the white mineral bloom that signals water is moving through the masonry. We’ve cleaned chimneys in Glassmanor where the homeowner assumed the discoloration was “just aging” when it was actually evidence of water infiltration that had already damaged the liner.
Then there’s the housing stock itself. These 1950s and 1960s Cape Cods and ramblers were built fast and built to a price. The clay-tile liners were adequate for coal and oil, fuels that burned hot and dry. Natural gas burns cooler and wetter. Put a 60,000-BTU gas furnace into a flue designed for 150,000 BTU of oil, and the exhaust cools before it exits, condensing acidic moisture on the liner surface. The clay tile spalls. The mortar between tiles deteriorates. The homeowner smells sulfur in damp weather and doesn’t know why. We’ve had this exact conversation on Owens Road, on Livingston Road, and in the blocks around Queen’s Chapel Road. It’s not a defect in any single chimney. It’s the predictable result of a fuel conversion that happened decades ago without a corresponding flue resize.
This is why annual inspection matters in Glassmanor more than in communities with newer housing or different conversion histories. The damage is usually hidden, usually progressive, and usually missed until it’s expensive. A Level-2 camera inspection takes about ninety minutes and ends with photos you can see and a plain-English verdict on what you’re looking at.

FAQs About Chimney Cleaning in Glassmanor
A standard Level-1 chimney sweep in Glassmanor typically costs between $180 and $260, while a Level-2 camera inspection with sweep runs $289 to $389. The exact price depends on flue accessibility, the amount of creosote buildup, and whether we find conditions that need documenting. We quote upfront before starting work, and estimates are always free. Call (301) 479-9806 for your specific price.
The National Fire Protection Association recommends annual inspection for all chimneys, and sweeping as needed based on what that inspection finds. In Glassmanor, with its 60-to-75-year-old clay-tile liners and humid summers that promote deterioration, we consider annual inspection non-negotiable. Many of our Glassmanor customers who burn wood regularly schedule sweeping every year; gas appliance chimneys may go longer between sweeps but still need that yearly look with a camera. Call (301) 479-9806 to set up a recurring annual appointment.
Clay tile can sometimes be repaired with HeatShield cerfractory resurfacing if the damage is limited to mortar joints and minor spalling. But in Glassmanor, we routinely find liners that are correctly sized for 150,000-BTU oil burners now serving 60,000-BTU gas furnaces - the chronic under-firing produces condensate that destroys clay from the inside out. When the liner is cracked, displaced, or fundamentally mismatched to the appliance, we recommend a stainless steel insert, typically DuraFlex, installed to the proper diameter for your current fuel type. We show you the camera footage and explain exactly what we’re seeing before you decide. Call (301) 479-9806 to schedule an inspection.
Uncleaned chimneys accumulate creosote, a flammable byproduct of wood combustion that ignites at approximately 451 degrees. A creosote-fueled chimney fire can reach 2,000 degrees, cracking liners and allowing flames to reach combustible framing. For gas appliances, the risks are different but equally serious: a blocked or deteriorated flue can vent carbon monoxide into living spaces rather than outdoors. In Glassmanor’s vintage housing stock, where original liners are already stressed by decades of condensate exposure, skipping inspection is gambling with odds that get worse every year. The $180-$260 cost of a sweep is cheap compared to a house fire or a hospital visit. Call (301) 479-9806 to get on the schedule.
That sulfur odor almost always indicates condensate accumulation in an oversized or deteriorated flue liner - the exact condition we find repeatedly in Glassmanor’s postwar housing stock. When a gas furnace’s cooler exhaust moves through a flue designed for hotter oil combustion, moisture condenses on the liner surface, mixes with combustion byproducts, and produces that characteristic rotten-egg smell when humidity rises. It’s not just unpleasant; it’s evidence that your liner is being chemically attacked. A Level-2 camera inspection will confirm the diagnosis and show you the extent of the damage. Call (301) 479-9806 to book - we’ll find the source and tell you plainly what it will take to fix it.
