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 North Kensington, MD
If you live in North Kensington and you’re wondering whether your chimney actually needs attention, here’s the short version: most chimneys in this neighborhood were built for oil-fired boilers in the 1940s and 1950s, and most of them have never been relined for the gas or wood appliances they heat with today. That combination creates draft problems, creosote buildup, and moisture damage that show up faster here than in newer parts of Montgomery County. We’ll come out, look at the flue with a camera, and tell you plainly whether it needs work or not. Call (240) 618-3233, and you’ll talk to a live person, not a voicemail box.
Top Hat Chimney is owned by Wendell Pike, who started this company in 1999 and still answers the phone himself more often than not. The sweep who shows up at your door in North Kensington works for Wendell, not for a franchise that rotated in last spring. Every job gets a written 90-Day Done Right Promise: if it’s not right, one call brings us back at no charge.

Why North Kensington Homeowners Choose Top Hat Chimney
North Kensington is a neighborhood where people talk. The houses along Plymouth Street and the blocks near Kensington Parkway have been turning over steadily for years, and the same questions come up at every closing: When was the chimney last swept? Is the liner intact? What’s the crown look like? We’ve been called out to enough of those closings to know how the conversation goes, and we write inspection reports that hold up when the buyer’s agent starts asking questions.
Ask anyone on your street. The houses near Rock Creek Hills and over by Beach Drive run into the same freeze-thaw cycle every winter, and the chimneys show it. Homeowners around Kensington Heights and Forest Glen call us for the same reason: the number Wendell gives you on the phone is the number on the invoice. No surprise line items, no “discovered issues” that double the price once the tools come off the truck. Background-checked, uniformed crews give you a real arrival window and call if it slips. And if the work isn’t done right, the 90-Day Done Right Promise is in writing on every single job.
We also honor a few standing offers North Kensington residents should know about: $40 off any repair over $200, a free second opinion on any competing written estimate, no trip charge for calls inside the county, and 10% off always for seniors and veterans.
Chimney Cleaning Services We Offer in North Kensington
Chimney Cleaning & Sweep
A standard sweep in North Kensington usually takes about an hour and a half from setup to cleanup. We brush the flue, vacuum the smoke chamber, and run a camera through the system to document what’s there. You get the footage and a plain-English verdict, every time, no exceptions.
Learn more about our Chimney Cleaning & Sweep in North Kensington.
Chimney Repair
North Kensington’s older masonry chimneys develop cracked mortar joints and spalled brick faster than most because of the freeze-thaw cycle we’ve already mentioned. We do tuckpointing, crown repair, flashing work, and smoke chamber parging, and we’ll show you the damage on camera before we quote a dollar amount.
Learn more about our Chimney Repair in North Kensington.
Fireplace Services
Whether you’ve got a wood-burning fireplace that drafts poorly or a gas insert that was installed decades ago, we service the whole system. That includes damper repair or replacement, fireback inspection, gas log servicing, and draft troubleshooting. If the problem is the flue size and not the fireplace itself, we’ll tell you that too.
Learn more about our Fireplace Services in North Kensington.
Chimney Cap & Crown
A missing or rusted cap lets rain, squirrels, and birds into the flue, and a cracking crown lets water into the masonry itself. We install and replace both, and we work with stainless steel caps that hold up to Maryland weather. If your cap just needs a screen replacement, we’ll say so instead of selling you a whole new unit.
Call (240) 618-3233 to schedule a cap or crown inspection in North Kensington.
Chimney Liner & Rebuild
This is the big one for North Kensington. Most of the original clay tile liners in this neighborhood’s 1940s and 1950s chimneys were sized for oil burners, not the gas or wood appliances that replaced them. When the flue is oversized or the tiles are cracked, we recommend stainless steel liners from brands we trust, including DuraFlex and HeatShield. We’ll always show you the camera footage that justifies the recommendation. If the chimney doesn’t need a liner, we won’t recommend one.
Call (240) 618-3233 for a liner assessment in North Kensington.

Why North Kensington’s Climate & Housing Affect Chimney Cleaning
North Kensington sits in the mid-Atlantic freeze-thaw band, where winter temperatures cross the 32°F mark dozens of times per season. Water gets into hairline cracks in mortar joints, freezes, expands, and widens the crack. That cycle repeats all winter, and the older brick chimneys in this neighborhood take the brunt of it. The proximity to Rock Creek valley also holds moisture longer, keeping brick wetter between cleaning cycles and making the freeze-thaw damage worse than in drier parts of the county. A chimney that looks fine in September can have spalled brick and cracked crown concrete by March.
The housing stock compounds the problem. North Kensington is almost entirely post-WWII construction, modest brick and frame homes built between the mid-1940s and early 1960s. Their chimneys were drafted for oil-fired boilers, with clay tile liners typically 8×8 or 8×12 inches. When those oil systems were swapped for gas furnaces or wood-burning inserts, no one retrofitted the flues with stainless steel liners. The result is an oversized flue that drafts poorly, cools the exhaust too quickly, and stages creosote faster than a properly sized liner would. First-degree creosote is a brush job. Third-degree is a glaze, catch it early.
There’s one more thing that makes North Kensington different from places like Germantown or Clarksburg: the steady turnover into the DC commuter market. When homes here change hands, chimney sweeps get called in specifically to produce written inspection reports for real estate transactions. The chimney condition becomes a negotiating point at closing. That means a Level 2 inspection, not just a basic cleaning, is often the default expectation for first calls in this area. We do those inspections regularly, and we write reports that buyers, sellers, and agents can all read without a translator.

FAQs About Chimney Cleaning in North Kensington
Once a year, burn or no burn. Chimneys break in the off-season too. Even if you haven’t used the fireplace much, the freeze-thaw cycle around Rock Creek valley is working on your mortar joints all winter, and an annual sweep includes a camera inspection that catches small problems before they become expensive ones. Call (240) 618-3233 to schedule your yearly sweep.
A standard chimney sweep with camera inspection in North Kensington typically runs $220 to $340, depending on flue size and roof access. If you’re preparing for a home sale and need a Level 2 inspection, expect $350 to $475. We quote upfront before any work begins. Call (240) 618-3233 for a free estimate.
The honest answer for North Kensington’s housing stock: if your chimney is original to a 1940s or 1950s home and was never relined after a fuel conversion, there’s a good chance the clay tiles are cracked or the flue is oversized for the current appliance. But we never recommend a liner without showing you the camera footage first. You’ll see the cracks yourself. If the flue is sound and properly sized, we’ll tell you that too, and we won’t sell you a liner you don’t need. Call (240) 618-3233, and we’ll show you what’s in your flue.
Creosote builds up, and creosote is fuel. A chimney fire burns hot enough to crack clay tiles and warp the metal components of your chimney, and it can spread into the house framing. Less dramatic but more common in North Kensington: moisture damage compounds over multiple winters, and a crown or mortar problem that costs a few hundred dollars to fix becomes a partial rebuild that costs thousands. Your flue doesn’t care how the fire looks. It cares how it breathes. Call (240) 618-3233 to get on the schedule.
Yes, and it’s a big part of our work in this neighborhood. North Kensington turns over homes steadily into the DC commuter market, and a chimney inspection is often required or requested at closing.

What North Kensington Customers Say
"Converted our old wood burner to gas and took the time to talk me out of the fancier insert I had picked out because it would have been wrong for the size of the room."
- Duane Kittering"Creosote build up was bad enough that he showed me a jar of it. Explained the difference between the stages and why the wood I had been burning was the cause. I have burned seasoned wood ever since."
- Gordon Selkirk"Turns up in the hat, which the children thought was the best thing that had ever happened, and left the hearth cleaner than he found it."
- Josefina Aranda
