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 Potomac
A chimney cleaning in Potomac usually runs $189 to $329 for a single flue, and most homes here need two to four flues serviced in one visit. That’s the reality of Potomac’s housing stock: large custom estates built from the 1960s through the 1980s, most with multiple wood-burning fireplaces that get used regularly. Wendell Pike and his crew have been inside those chimneys since 1999, and we’ll give you a straight answer before a single tool comes off the truck. Call (240) 716-5865 and you’ll talk to a live person, not a call center.
We’re a locally owned, owner-operated outfit serving Potomac from our Washington, DC metro office. Our Chimney Cleaning & Sweep crew knows the difference between a colonial off Democracy Boulevard and a Georgian near Avenel. That matters when you’re looking at three flues on a steep roofline and trying to figure out which one has the draft problem.
Why Top Hat Chimney Is Potomac’s Preferred Chimney Cleaning & Sweep Company
Ask anyone on your street. Wendell has been working Potomac chimneys for over 29 years, going back to 1999, and he puts his name on every job. That’s not a marketing line. It’s the kind of accountability you get when the owner answers the phone and then shows up in uniform, background-checked, ready to climb on your roof.
Potomac homeowners call us because they’ve been burned by the national outfits. The ones that quote $149 on the phone, send a stranger in a rental van, and suddenly discover $4,000 worth of “urgent” liner work. We do things differently. The price you get on the phone is the number on the invoice. If something’s wrong, we show you camera footage of exactly what we found. No pressure, no scare tactics. And every job carries our 90-Day Done Right Promise in writing: if it’s not right, one call brings Wendell back, free.
We know the homes here. The custom colonials off River Road, the Georgians with original clay tile flue liners dating back to the Kennedy administration, the estate properties where three generations of one family have been burning wood every winter. That local knowledge means we arrive already knowing what to expect, not still guessing while we set up the ladder.
Our Chimney Cleaning & Sweep Services in Potomac
Level 1 Inspection
A Level 1 inspection is the standard annual checkup for a chimney that hasn’t changed since the last cleaning. Here in Potomac, most homeowners get this done alongside their fall sweep, and it’s the smart way to catch problems before the burn season starts. We inspect the readily accessible portions of the flue, fireplace, and chimney exterior, then tell you plainly if everything looks right. If it doesn’t, you’ll see the camera footage and hear exactly what needs doing and whether it can wait.
Level 2 Inspection
If you’ve converted a wood-burning fireplace to a gas insert, had a chimney fire, experienced a weather event, or you’re buying or selling a home in Potomac, you need a Level 2 inspection. This goes deeper than a visual sweep. We run a camera down every flue and document the condition of the clay tile liners, which in many Potomac homes are 40 to 55 years old. Montgomery County requires a liner certification before a gas appliance permit is issued, so if you’re converting to gas, don’t skip this. The camera footage and a plain-English verdict: every time, no exceptions.
Creosote Removal
First-degree creosote is a brush job. Third-degree is a glaze, catch it early. Potomac homeowners who burn wood regularly build up creosote faster than folks in Rockville or Bethesda for reasons we’ll explain below. Our crew handles first and second-degree creosote with rotary brushes and HEPA vacuums that keep the soot out of your living room. If we find third-degree glaze, we’ll tell you straight and walk you through the options, including chemical treatments or a HeatShield relining if the structure’s compromised.
Soot Removal
Gas fireplaces produce soot too, just differently. The fine, powdery residue from a gas insert clings to the firebox and glass, and on Potomac estates with decorative gas logs that get run every evening all winter, it builds up surprisingly fast. We clean gas fireplaces thoroughly without scratching the ceramic glass or disturbing the catalytic components, and we’ll show you the before-and-after of the firebox before we pack up.
Annual Sweep
Once a year, burn or no burn. Chimneys break in the off-season too. The annual sweep is the backbone of what we do in Potomac, and with the number of multi-flue homes here, it often means servicing three or four chimneys on a single property. We schedule around your calendar, give you a real arrival window, and call if we’re running behind. For seniors and veterans, we always take 10% off.

Common Chimney Cleaning & Sweep Problems We See in Potomac Homes
- Aging clay tile flue liners cracked or offset after decades of thermal cycling. Most Potomac homes built between 1965 and 1990 have original clay tile liners that are now well past their design life. Once a liner cracks, carbon monoxide can leak into the house, and you won’t know it without a camera inspection.
- Freeze-thaw spalling on exposed chimney crowns due to river-valley humidity. The Potomac River keeps ambient moisture high year-round, and water seeps into hairline cracks in brick crowns, then freezes overnight. Repeat that a few dozen times and the crown starts crumbling. This is especially common on the tall chimneys of large Potomac rooflines.
- Multiple flues with varying creosote stages requiring different treatment. On two to five-flue estates, it’s rare to find every flue in the same condition. One might be clean, another with first-degree creosote, a third with second-degree. That demands separate brushes, separate vacuums, and a methodical approach, not a rushed 45-minute job.
- Improperly relined gas insert conversions from the 1990s and 2000s. Many Potomac homeowners converted wood fireplaces to gas inserts during the renovation boom without relining the original clay tile flue. The old flue was never sized for gas exhaust, and now it’s a hidden draft and CO hazard. We find this on a lot of Level 2 inspections.

FAQs - Chimney Cleaning & Sweep in Potomac
A typical Potomac estate home has two to five wood-burning fireplaces, so one cleaning visit routinely covers three or four flues. Each flue gets its own brush and vacuum pass, and we inspect the liner and firebox separately. Call (240) 716-5865 with your fireplace count and we’ll give you an exact price before we come out.
Yes. Montgomery County requires a chimney inspection and liner certification before a gas appliance permit is issued for a fireplace conversion. A Level 2 inspection with camera documentation is the standard way to satisfy that requirement, and it’s exactly what we perform before anyone relines or installs an insert.
The river valley north of the Potomac traps cooler overnight air, so Potomac homeowners start burning wood earlier in the fall and keep burning later into the spring than surrounding areas. Combined with the heavily wooded lots that produce slower, cooler fires, that extended burn season produces more creosote per flue. Call (240) 716-5865 to schedule a sweep before the fall rush.
Third-degree creosote is a shiny, tar-like glaze that standard rotary brushes can’t remove. It requires chemical treatments, specialized tools, and sometimes a liner replacement to fully address. We’ll tell you honestly what stage you’re dealing with after a camera inspection, and we won’t recommend a fix you don’t need.
Expect a camera inspection of the flue before any brushing happens. On a 40 to 55-year-old clay tile liner, we’re looking for hairline cracks, offsets between tile sections, and signs of water intrusion. If the liner is sound, we proceed with the sweep. If it’s not, you’ll see the footage and get a straight answer about what needs to happen and what can wait. Call (240) 716-5865 for an exact quote. Estimates are free.
