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.

AfterChimney Cleaning Services in South Kensington, MD
If you own one of the older homes near the Kensington border, you already know the drill: the chimney has been there since before your grandparents were born, and it hasn’t been looked at in years. A sweep in South Kensington typically runs $180 to $340, depending on flue condition and access, and it usually takes about an hour once we’re on the roof. Most South Kensington homeowners call us because they’ve noticed a smell when the AC kicks on, or because their gas logs have been burning “fine” for a decade and nobody’s ever actually looked inside the flue. Call (240) 716-5865 and Wendell or one of his crew will set a real arrival window, not a four-hour guess.
We know these chimneys. The Victorian stacks off Summit Avenue, the brick colonials along Connecticut Avenue, the Cape Cods tucked into the shaded lots near Rock Creek: we’ve swept, repaired, and rebuilt more of them than we can count. Top Hat Chimney has been around since 1999 because we tell people the truth: sometimes a fireplace needs a full rebuild, and sometimes it needs a $200 sweep and a new cap. Either way, you’ll see the camera footage before you spend a dollar on repairs.

Why South Kensington Homeowners Choose Top Hat Chimney
Wendell Pike founded Top Hat Chimney in 1999, and he still puts his name on every invoice. That matters in a community like South Kensington, where word travels down Kensington Parkway and through the neighborhoods around Stoneybrook and Rock Creek Hills faster than any ad campaign. Homeowners here have been burned by national outfits that send a stranger in a wrapped van, quote one number on the phone, and leave a different one on the clipboard. Wendell runs into you at the hardware store on Saturday. He’d rather do the job right than explain why he didn’t.
Every Top Hat technician is background-checked, shows up in uniform, and gives you a straight number before a single tool comes off the truck. The 90-Day Done Right Promise is in writing on every job: if the work isn’t right, one call brings the crew back at no charge. We answer the phone 24/7 with a live person, and at odd hours it’s often Wendell himself. And for South Kensington homeowners, the free camera inspection means you never have to take a chimney company’s word for what’s inside your flue. You’ll see it with your own eyes.
Chimney Cleaning Services We Offer in South Kensington
Chimney Cleaning & Sweep
A full sweep removes creosote, soot, and blockages from the flue, smoke chamber, and firebox. In South Kensington’s older homes, we also check for the clay tile deterioration that turns a routine cleaning into a bigger conversation. If it’s clean, we’ll say so. If it’s not, you’ll see the video.

Chimney Repair
Spalled brick, cracked mortar joints, failing flashing, damaged crowns: these are the repairs South Kensington’s freeze-thaw cycles create every winter. We match mortar color and texture, rebuild crowns with proper overhang, and fix flashing so water stays outside where it belongs.

Fireplace Services
From gas log inspections to damper replacement and firebox rebuilding, we handle the whole system, not just the pipe above it. If your fireplace drafts poorly or the damper has been stuck open since you moved in, we can usually fix it in one visit.

Chimney Cap & Crown
A cracked crown or a missing cap is the easiest way for water to get where it should never go. We install stainless steel caps and rebuild crowns with a proper drip edge, sized to the flue and the weather this chimney has to stand up to.
Chimney Liner & Rebuild
When the original clay tile liner has cracked, shifted, or is simply the wrong size for a gas appliance, a chimney liner & rebuild with DuraFlex or HeatShield systems is what we recommend. For chimneys that have failed structurally, we do full rebuilds from the roofline up, with matching brick and proper flashing.

Why South Kensington’s Climate & Housing Affect Chimney Cleaning
South Kensington borders Kensington, one of Montgomery County’s oldest planned communities, platted in the 1890s when Washington families rode the B&O up from the city to escape the summer heat. That history left South Kensington with a concentration of late-19th and early-20th century masonry chimneys you won’t find in the newer subdivisions of Germantown or Gaithersburg. Many of those original multi-flue stacks served coal or wood systems that were later converted to gas without proper relining. The result: undersized, deteriorating clay-tile flues venting corrosive gas exhaust. We see this pattern constantly in the Victorians and Craftsman homes east of Connecticut Avenue.
Then there’s the water. Montgomery County’s freeze-thaw cycles, running from November through March, push micro-cracks in brick and mortar wide open, season after season. And on the shaded, wooded lots near the Rock Creek tributaries, chimney masonry stays damp longer after rain, so moss moves in and the crown deteriorates faster than it would on a sunny suburban lot. The technicians who work the hillside streets near Rock Creek routinely find chronic flashing failures and interior water staining that homeowners have been calling “roof leaks” for years. It’s not the roof. It’s the chimney, and the fix is usually simpler and cheaper than they feared.

FAQs About Chimney Cleaning in South Kensington
A standard sweep in South Kensington runs $180 to $280 for most single-flue chimneys, and $220 to $340 if you want the full camera inspection. Older multi-flue Victorian stacks may run higher because of access and additional flues. Call (240) 716-5865 for an exact quote; estimates are free and there’s no trip charge inside the county.
Once a year, whether you burn or not. The National Fire Protection Association recommends annual inspection, and in South Kensington’s older homes, the off-season is when masonry deteriorates and animals move in. If it’s been more than a year, call (240) 716-5865 and we’ll get you on the schedule.
Sometimes you do, and sometimes you don’t; that’s exactly why we put a camera in the flue every single time. If the clay tiles are cracked or missing, corrosive gas exhaust is eating at the masonry, and a stainless liner from DuraFlex or a HeatShield coating is the right fix. If the liner is fine, we’ll tell you it’s fine and you’ll pay for the sweep and nothing else. Call (240) 716-5865 and see the footage yourself.
Creosote keeps building up, and third-degree glazed creosote is a fight to remove. Animals nest in uncapped flues. Water from a cracked crown seeps down and spalls the brick. Worst case, a chimney fire or carbon monoxide backup becomes a real possibility. The interesting thing: most of these problems are cheap to prevent and expensive to fix.
Very often, yes. On the shaded hillside streets near Rock Creek, what looks like roof failure is usually flashing or crown failure at the chimney. We fix the flashing, rebuild the crown, and the interior staining stops. When we give you a verdict, it comes with camera footage and a plain-English explanation, every time. Call (240) 716-5865 and we’ll take a look.

What South Kensington Customers Say
"He repointed the crown and waterproofed the stack, and two winters on there is not a damp mark on the ceiling where there used to be one every February."
- Harold Vance"Gave me the photos from inside the flue on a memory stick along with the invoice. I have never had a trade hand me evidence before."
- Priscilla Ng"Wendell has swept our chimney every autumn for six years now. He knows the flue better than I know it and he tells me when it does not need doing, which is not something most trades will admit to."
