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.

Our Fireplace Services in South Kensington
Gas Fireplace Service
Many South Kensington homes built before World War II originally burned coal or wood, then converted to gas during the 1950s and 60s. That conversion often left the original clay tile flue in place, which is exactly the wrong liner for a gas appliance. Gas produces acidic condensate that eats away at old clay tiles from the inside. We service vented and vent-free gas logs, clean burner assemblies, check thermocouples and gas valves, and inspect the flue for the kind of corrosive damage that’s common in South Kensington’s converted Victorian and Craftsman-era chimneys.
Wood Burning Fireplace
A wood-burning fireplace on a shaded South Kensington street faces more than occasional use. The tree canopy near the Rock Creek drainage area keeps chimney masonry damp longer after rain, which accelerates the freeze-thaw damage that cracks mortar joints and lets water into the flue. We sweep and inspect the full system: firebox, damper, smoke chamber, flue liner, crown, and cap. Ask anyone on your street. The homes here were built with real masonry, but masonry doesn’t last forever, and Montgomery County winters are hard on it.
Fireplace Insert
If your South Kensington home still has an open-hearth fireplace from the 1910s or 1920s, you’re losing more heat up the chimney than you’re putting into the room. An insert changes that. We install wood, gas, and pellet inserts, and we’re particular about the liner that goes with them. A properly sized stainless liner from Olympia Chimney or DuraFlex makes the difference between an insert that drafts well and one that fogs the glass and sends combustion gases where they shouldn’t go. We don’t cut corners on liner sizing.
Damper Repair
A damper that won’t close fully is a year-round problem in South Kensington. It lets warm air escape all winter, and during the humid months it lets damp, musty air from the flue drift back into the living room. We repair and replace throat dampers, and for many older fireplaces we recommend a top-sealing damper that actually closes at the top of the flue instead of the firebox. That upgrade alone stops a surprising amount of energy loss and keeps animals and debris out of the chimney.
Firebox Repair, Fireplace Conversion, and More
We also rebuild fireboxes with proper refractory materials, convert wood fireplaces to gas, repair or replace chimney caps, and fix the flashing where the stack meets the roof on the Cape Cods and colonials south of the train tracks. If you’re not sure what’s wrong, we start with a camera inspection and show you the footage. You’ll see what we see, and we’ll explain the fix in plain English before quoting anything.
Trusted Brands We Service in South Kensington
Our South Kensington customers don’t always know the brand of their fireplace or insert, but the nameplate tells us what we need to know. We service and install products from HeatShield, Gelco, Olympia Chimney, and Famco, among others. Having direct factory relationships means we can source the right replacement part quickly rather than rigging something that sort of fits. If your insert needs a new blower or your gas valve needs a specific thermopile for a Famco unit, we can usually have it in hand within days, not weeks.
Common Fireplace Services Problems We See in South Kensington Homes
- Cracked chimney crowns on pre-1940 masonry stacks. The 1890s-era Victorians and early Craftsman homes near the Kensington border were built with thick masonry and original clay flue tiles. Water sits on the crown after a storm, freezes, and pops the mortar wash line apart. The crack lets storm water stream down through the brick and into the attic.
- Displaced or corroded chimney caps after severe weather. Wind and driving rain push old galvanized caps off level or tear them loose altogether. Once the cap is gone, leaves, rain, and the occasional squirrel fall straight down the flue.
- Flashing failures that mimic roof leaks. On the 1940s-1960s Cape Cods and brick colonials built along Connecticut Avenue, the flashing where the stack penetrates the roof was often sealed with roofing tar and roofing paper that eventually fails. The water follows the chimney and stains the ceiling below, so homeowners call a roofer and the roofer patches the wrong thing.
- Damp firebox surfaces and spalling brick. The wooded lots and shaded hillsides around the Rock Creek tributaries keep chimney masonry wet for days after every rain. When water is held against brick faces long enough, the faces pop off, leaving fragments on the ground and exposing the softer inner brick to even more water.
Pricing for Fireplace Services in South Kensington, MD
Here’s what you can expect in the South Kensington market. A standard fireplace inspection with camera typically runs $195 to $275. A gas fireplace service appointment, including cleaning and testing the burner and safety shutoffs, sits between $175 and $250 for most single-log sets. Damper repair or replacement starts around $220 and can go to $475 if the damper needs to be custom-fitted for an older firebox. Chimney cap replacement with a stainless unit from Olympia runs $350 to $650 installed, depending on the flue size and whether the crown needs patching first.
What affects the price most is what we find once the camera goes up the flue. A cracked crown is a $400 to $700 repair. A flashing replacement is $450 to $900. Full fireplace insert installation is a bigger job and starts around $3,500 including the liner, and ranges up from there. We give you the number before we start. Call (240) 716-5865 for a free estimate. And remember: $40 off any repair over $200, and 10% off for seniors and veterans.

A South Kensington Failure Pattern Most Generic Fireplace Pages Never Mention
South Kensington sits against Kensington, one of Montgomery County’s oldest planned communities, platted back in the 1890s as a summer retreat for Washington families escaping the heat. That history left this area with a density of late-19th and early-20th century masonry chimneys that you don’t find ten minutes up the road in Germantown or Gaithersburg. Many of those original multi-flue stacks served coal or wood-burning systems that were later converted to gas without proper relining. The original clay tile flues were sized for coal smoke, not for gas condensate, and they’ve spent decades deteriorating from the inside while the outside brick holds up well enough to hide it.
On a shaded hillside street near the Rock Creek drainage, we pulled a storm-bent galvanized cap off a 1920s Craftsman and found the flue tile spalled from years of freeze-thaw cycles. The crown was cracked at the wash line and condensate was weeping through the brick. The homeowner had been told by two roofers that the ceiling stain was a roof leak. We installed a new stainless cap, sealed the crown with HeatShield, and rerouted the flashing to stop the water at the penetration point. The stain dried up and never came back. That’s the kind of finding a generic fireplace services page never mentions, because a generic company never sees it.

FAQs - Fireplace Services in South Kensington
Stand across the street and look for any obvious tilt or missing chimney cap, then go inside and check the ceiling and wall surfaces around the chimney chase for fresh staining. If you see a new stain, call us at (240) 716-5865 before you build a fire. Storm-driven water can sit in the flue and get forced down the smoke chamber once heat rises. We’ll run a camera up the flue and show you what’s actually happening before recommending anything.

Homes near the Kensington border date back to the 1890s and early 1900s, and many still have original masonry crowns that were built with simple mortar wash lines rather than poured concrete. A century of Montgomery County freeze-thaw cycles, from November through March, expands and contracts that mortar until it cracks. Once water gets into the crack, the next freeze pushes it wider. Call us for an inspection and we’ll tell you if the crown can be sealed with HeatShield or needs to be recast. A free estimate is part of the service.

Yes, and in South Kensington it happens constantly. Water that enters through a cracked crown or failed flashing follows the chimney structure downward, travels along framing members, and shows up as a stain on a ceiling ten feet away from the chimney. Roofers often patch the roof and the stain returns with the next rain. We find these misdiagnosed leaks on a regular basis in the Cape Cods and colonials along Connecticut Avenue and on the shaded hillside streets near Rock Creek. If your roof has been patched and the stain came back, call us at (240) 716-5865 before you pay for another roof repair.

Absolutely, especially in South Kensington where many fireplaces originally burned coal or wood and were converted to gas decades ago without relining. Your flue doesn’t care how the fire looks. It cares how it breathes. Gas exhaust produces acidic condensate that corrodes older clay tile liners from the inside out. An inspection is quick, and we’ll show you the camera footage right on our tablet so you can see the liner condition for yourself. The inspection typically runs $195 to $275, which is cheap compared to a liner replacement that could have been caught earlier.

Flashing failure, by a wide margin. The shaded canopy keeps the chimney crown and stack damp longer after rain, and the grade on those hillside lots channels runoff directly toward the stack. The flashing that was installed fifty years ago with roofing tar loses adhesion and pulls away from the brick. Water follows the gap down into the attic and the firebox, and the brick faces start spalling. We fix this with proper stepped flashing and counter-flashing sealed to the masonry. If you see a damp smell or damp brick inside the firebox after a rain, call us at (240) 716-5865 and we’ll find the entry point.
