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 Glenmont, MD
Glenmont sits right along the Georgia Avenue corridor, and if you drive those residential streets between Randolph Road and Layhill, you’ll pass block after block of 1950s and 1960s Cape Cods and split-levels. Those houses share something else too: masonry chimneys that are now 50 to 75 years old, most of them with dual flues that once served both a fireplace and an oil furnace. When you call Top Hat Chimney at (240) 716-5865, you reach a live person, and the sweep who comes to your door in Glenmont is someone Wendell Pike trained and stands behind. We’re not running call centers or rotating crews through town. We answer the phone, we show up, we do the job right, and we put a 90-Day Done Right Promise behind it, in writing, every time.

Why Glenmont Homeowners Choose Top Hat Chimney
Wendell Pike started Top Hat Chimney in 1999, and he still runs the company himself. In Glenmont, our crews work regularly in neighborhoods like Glenmont Forest, Wheaton Woods, and the stretch of split-levels along Georgia Avenue south of the Glenmont Metro. Ask anyone on your street. We hear the same two complaints about the national chains: the price changed at the door, and the technician was unreachable afterward. That does not happen with us. The number you hear on the phone is the number on the invoice, and every job, from a basic sweep to a full liner rebuild, is backed by the 90-Day Done Right Promise. If something isn’t right, one call brings the crew back, no charge. We’re licensed, insured, and we publish our address and license number because Wendell puts his name on the work and runs into you again on Saturday.
We also answer the phone around the clock. Not a voicemail box, not a call center. A live person, twenty-four hours a day, seven days a week, and it may well be Wendell himself picking up at midnight because your chimney is making a noise you don’t like. That matters in Glenmont, where so many of these mid-century chimneys have hidden problems you won’t see until a camera goes down the flue.
Chimney Cleaning Services We Offer in Glenmont
Chimney Cleaning & Sweep
A proper sweep here is more than running a brush up the flue. We remove creosote and debris, inspect the firebox and smoke shelf, and document everything with a camera so you see exactly what we saw. First-degree creosote is a brush job. Third-degree is a glaze, and catching it early saves you a liner replacement later. Learn more about our Chimney Cleaning & Sweep in Glenmont.
Chimney Repair
Glenmont’s mid-century brick chimneys have reached the age where mortar joints are cracking, terra cotta tiles are spalling, and water is getting into places it shouldn’t. We repair crowns, tuckpoint joints, rebuild fireboxes, and replace damaged flue sections. Nothing gets recommended without camera evidence you can review for yourself. Learn more about our Chimney Repair in Glenmont.
Fireplace Services
From gas log installation to damper repair to full fireplace rebuilds, we handle the inside of the firebox with the same care we give the flue above it. If your fireplace smokes when you light it, or the damper won’t seal, we’ll find out why and show you. Learn more about our Fireplace Services in Glenmont.
Chimney Cap & Crown
An uncapped or poorly crowned chimney is the single most common cause of Chimney Cap & Crown - Glenmont water damage we see. We install stainless steel caps, rebuild damaged crowns, and seal everything so rain, birds, and squirrels stay out. In these older Montgomery County neighborhoods, a missing cap usually means a flue full of debris within a season or two.
Chimney Liner & Rebuild
When the original terra cotta liner has cracked or collapsed, we handle Chimney Liner & Rebuild - Glenmont work with stainless steel liners from trusted brands like HeatShield, Olympia Chimney, or Famco. On many Glenmont split-levels, the old oil-furnace flue was capped at the firebox level decades ago and left to fill with water and tile fragments. We can cap it properly, repurpose it, or replace it depending on what the camera shows.
Neighborhoods We Serve in Glenmont
We cover all of Glenmont, from the neighborhoods around the Glenmont Metro and Glenmont Local Park up through the residential streets near Wheaton Regional Park. Typical response time for a chimney cleaning appointment in Glenmont is within a few business days; during the fall rush, call a week or two ahead of when you want to burn.

Why Glenmont’s Climate & Housing Affect Chimney Cleaning
Glenmont’s housing stock is concentrated in mid-century single-family homes built between roughly 1948 and 1975. Almost every one of them has an original full brick masonry chimney, and that means 50 to 75 years of Montgomery County weather. The county’s winters bring repeated freeze-thaw cycles, with temperatures crossing 32°F many times each season. Water seeps into hairline cracks in the brick and mortar, freezes, expands, and widens those cracks a fraction of an inch at a time. Then the humid summers come, and moss and efflorescence take hold in the compromised joints. This cycle does not happen to the same degree in newer construction or in homes with factory-built chimneys. It happens in Glenmont, and it means your chimney needs an annual inspection whether you burn fires or not. Once a year, burn or no burn. Chimneys break in the off-season too.
There’s another issue that a sweep working in Glenmont sees more than almost anywhere else in the metro area. These Cape Cods and split-levels were built with dual-flue masonry chimneys. One flue served the wood-burning fireplace in the living room. The other served an oil-fired furnace in the basement. When the oil furnace was replaced with a high-efficiency gas unit vented through PVC pipe, the old furnace flue was simply capped at the firebox level and forgotten. On many Glenmont-area split-levels, that abandoned flue shares a brick chase with the active fireplace flue. We routinely find those abandoned flues packed with bird nests, collapsed tile fragments, and standing water, and because it sits right next to the flue you’re actually using, it can silently compromise that active flue without any visible warning. The outside of the chimney looks fine. The inside is a different story. That’s why we never sweep a Glenmont chimney without running a camera through every flue in the structure, active or not.

FAQs About Chimney Cleaning in Glenmont
A standard chimney cleaning and inspection in Glenmont typically costs between $229 and $329 depending on flue size, creosote buildup, and whether the chimney has multiple flues that need attention. You’ll get your exact price on the phone before we arrive, and the number you hear is the number on the invoice. Call (240) 716-5865 for a free estimate.
Once a year, burn or no burn. In Glenmont’s mid-century homes, freeze-thaw cycles and summer humidity work on your brick and mortar year-round, and the off-season is when water intrusion and animals do their damage. An annual inspection catches cracked tiles, damaged crowns, and abandoned flue problems before they become expensive repairs.
Not necessarily, and you should not take anyone’s word for it unless they show you camera footage of the actual damage. We run a camera through every flue and show you the footage before recommending any liner work. If the terra cotta tiles are intact and the flue passes inspection, we’ll tell you plainly that it’s fine and can wait. Nobody at Top Hat Chimney gets a commission for selling liners. We get paid to tell you the truth.
Creosote builds up. First-degree creosote brushes out easily. Third-degree creosote is a hard glaze that requires chemical treatment or a liner replacement. If you skip sweeps long enough, you can end up with a chimney fire, a cracked liner you didn’t know about, and carbon monoxide leaking into the house. We see it in Glenmont regularly, especially in abandoned furnace flues that were capped and forgotten. Call (240) 716-5865 and get on the schedule before burning season.
Yes, and we do it on every Glenmont job where the home has a dual-flue chimney. Those old oil-furnace flues are rarely safe to use as-is, and many are packed with debris and water. We’ll camera the flue, show you what’s inside, and tell you honestly whether it needs to be capped, cleaned, or relined. No scare tactics, no pressure. Just the camera footage and a plain-English verdict, every time, no exceptions.

- Rosalind Achebe"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."
