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.

AfterFast, Reliable Chimney Cleaning & Sweep Across South Kensington
Chimney cleaning in South Kensington usually takes 45 to 90 minutes and costs between $189 and $279 for a standard sweep with a Level 1 inspection. If your home was built between 1945 and 1970, the odds are good that your flue was sized for an oil furnace that no longer exists, and that changes what a proper cleaning needs to include. Wendell Pike and his crew have worked these blocks long enough to know which Capes still have their original clay tile and which colonials converted to gas thirty years ago. Call (240) 618-3233 and Wendell will tell you straight whether you need a sweep, an inspection, or nothing at all.
Why Top Hat Chimney Is South Kensington’s Preferred Chimney Cleaning & Sweep Company
Wendell founded Top Hat Chimney in 1999 and has been inside enough South Kensington flues to recognize a spalled tile from the sound the brush makes before the camera ever goes up. He runs the company owner-operated, which means the number on the truck is his number, and the guy on the phone at 2 a.m. may well be him. Every job gets the 90-Day Done Right Promise in writing. If it’s not right, one call brings him back, no charge, no argument.
South Kensington homeowners have dealt with the national chains that quote $99 on the phone and hand over a $1,400 liner invoice at the door. That does not happen here. Wendell gives upfront pricing before a single tool comes off the truck, and the number you hear is the number on the invoice. His crew is background-checked and uniformed, and they call if the arrival window slips. Ask anyone on your street. The homes here are too particular for a one-size-fits-all operation.
Our Chimney Cleaning & Sweep Services in South Kensington
Level 1 Inspection
A Level 1 inspection comes standard with every sweep in South Kensington and covers the readily accessible portions of the chimney interior and exterior. For a mid-century colonial or Cape Cod with a single fireplace and no known issues, this is usually all you need. We check the flue, the cap, the crown, and the firebox, then document everything in a written report. If we see something that needs a closer look, we tell you on the spot and show you why.
Level 2 Inspection
You want a Level 2 inspection in South Kensington any time the house has changed heating fuels, had a chimney fire, or gone through a sale. The camera goes into the flue and Wendell walks you through the footage on screen, tile by tile. Given how many Capes and colonials here converted from oil to gas decades ago, a Level 2 is the only way to catch the condensation damage and spalling that a brush alone cannot reach. This is the inspection that answers the question every South Kensington homeowner asks before approving a liner: show me.
Creosote Removal
Creosote comes in degrees. First-degree creosote is a brush job. Third-degree is a glaze, hard and shiny, concentrated in the upper flue where the cooled smoke condenses against warm Maryland air. In South Kensington, the mature oaks and maples that shade so many lots keep flue temperatures lower, which means creosote accumulates faster here than on open suburban blocks. Wendell determines the degree before he decides the method. You will know what he found because he will show you.
Soot Removal
Soot removal in South Kensington is straightforward because most fireplaces here burn seasoned hardwood. The soot is dry, loose, and responds well to a rotary whip or brush. But when soot has been allowed to build up season after season, or when the chimney also vents a gas appliance, we will often find a sticky, tar-like layer underneath the powder that standard brushing misses. That is why every soot removal here includes a flue-surface check, not just a pass with the brush.

Trusted Brands We Service in South Kensington
Wendell installs and services liners from DuraFlex and HeatShield, along with caps and dampers from Famco and Copperfield. When a South Kensington chimney needs a stainless-steel liner after a fuel-switch inspection, Wendell stocks the common sizes so you are not waiting on a parts shipment. These are the brands the certified sweeps trust, and Wendell has installed enough of them in Montgomery County to know which ones hold up under Maryland freeze-thaw cycles. The camera footage and a plain-English verdict, every time, no exceptions.
Common Chimney Cleaning & Sweep Problems We See in South Kensington Homes
- Oversized flues after oil-to-gas conversion. The original clay-tile flue was sized for a high-BTU oil furnace. The gas furnace that replaced it runs much cooler, and the oversized flue never warms up enough to push exhaust out. Condensation forms, soaks into the tile, and accelerates spalling. A standard sweep will not catch this. A Level 2 will.
- Spalled clay tiles blocking the flue. Freeze-thaw cycling between November and March pushes water into hairline cracks in South Kensington’s original clay liners. Over years the tile faces flake off and drop into the flue, creating blockages that look like draft problems from the outside. Wendell finds these with the camera before they become chimney fires.
- Animal nests and leaf debris near the Rock Creek watershed corridor. If your lot is shaded by mature oaks or maples, chimney swifts and gray squirrels see an unscreened flue cap as a vacancy sign. We routinely pull partial blockages from South Kensington chimneys that homeowners swore were just weak draft. A proper cap with a screen solves it permanently.
- Chimney crowns cracked by canopy shade and humidity. The north-facing chimney faces on South Kensington’s tree-lined streets hold summer moisture, and moss and efflorescence follow. The crown was likely original to the house, and a cracked crown lets water straight into the mortar bed. We check the crown on every sweep and make a recommendation only when the camera shows it failing.
Pricing for Chimney Cleaning & Sweep in South Kensington, MD
A standard chimney sweep with Level 1 inspection in South Kensington runs $189 to $279 depending on flue height, creosote degree, and whether the chimney also vents a heating appliance. A Level 2 inspection with full camera documentation is $349 to $449 and is worth doing if the house converted from oil to gas or you just bought it. Creosote removal for glazed, third-degree deposits starts at $350 and goes up with flue length. Soot removal is included with the standard sweep; if it requires an extra rotary treatment, expect $75 to $125 more. No trip charge applies inside the county, and every quote is a flat price you agree to before work begins. Call (240) 618-3233 for an exact number. Estimates are free, and Wendell will tell you honestly if a sweep is all you need this year.

FAQs - Chimney Cleaning & Sweep in South Kensington
Because the flue your gas furnace vents into was almost certainly sized for the oil furnace the house was built with. Oversized clay-tile flues carry low-temperature gas exhaust too slowly, and the resulting condensation gets absorbed into the tile. Over ten or fifteen years that saturates the liner and causes spalling, which can block the flue or expose the masonry behind it. A Level 2 inspection with a camera is the only way to see what has happened inside. Call (240) 618-3233 and Wendell will schedule the inspection and show you the footage himself.
Third-degree creosote is a hard, shiny glaze that forms when flue temperatures stay low and the smoke cools before it exits. In South Kensington, the dense tree canopy keeps chimney exteriors cooler, which makes glaze more common on shaded lots than on open streets. You can sometimes see a dark, tar-like coating when you shine a light up the flue, but Wendell confirms the degree with a camera before he chooses a removal method. If it is third-degree, brushing alone will not remove it, and you should not burn until it is gone. Call (240) 618-3233 for an inspection.
Yes. A Level 2 inspection uses a camera that travels the full length of the flue and records the condition of every tile. Wendell walks you through that footage on site, so you see the flaked tile faces and dropped debris yourself before anyone recommends a liner. No recommendation is made in South Kensington without camera evidence the homeowner can see with their own eyes. That is the rule, every job, no exceptions.
It is common here, and it usually traces back to the fuel-switch problem or to a partially blocked flue. Cold Maryland air cools the chimney faster, and if the flue is oversized for a gas appliance or partially packed with leaf debris from your trees, the draft collapses in January. Wendell checks both possibilities on the first visit. Often the fix is a properly sized liner or a screened cap, not a rebuild. Call (240) 618-3233 and describe what you are seeing; Wendell will tell you what is likely before he even arrives.
Constantly, especially on the tree-lined blocks near the Rock Creek watershed corridor. Chimney swifts nest in unscreened flues between May and August, and gray squirrels will colonize an open chimney in a week. Oak leaves pack into flue crowns every fall, and homeowners mistake the weakened draft for a structural problem when the real issue is organic material blocking the top of the flue. A proper cap with an animal screen fixes it, and Wendell can install one on the same visit.
