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.
Fast, Reliable Chimney Liner & Rebuild Across Chevy Chase
Chimney liner replacement and rebuild work in Chevy Chase, MD typically runs $2,800 to $7,500 depending on whether you need a stainless steel liner, HeatShield resurfacing, or a partial rebuild of the crown and smoke chamber. Most jobs take one to two days once the materials are on site. If you’re reading this from a 1920s Colonial off Western Avenue or a Tudor Revival near Connecticut Avenue, you’re likely dealing with a chimney that was built for coal, not for the gas insert someone installed in 2007. We know these chimneys. Wendell Pike started Top Hat Chimney in 1999, and his crews have been through more Chevy Chase flues than we can count. Call (240) 716-5865 and Wendell or one of his crew will actually answer.
Why Top Hat Chimney Is Chevy Chase’s Preferred Chimney Liner & Rebuild Company
Chevy Chase is a small, tight-knit collection of neighborhoods where word travels fast. Ask anyone on your street. The houses here are not generic. They were built by the Chevy Chase Land Company between the 1910s and the 1940s, and nearly every chimney on the block is a century old. That means the local work comes down to one thing more than any other: matching a modern liner and venting setup to a masonry stack that was never designed for it. A national chain that rotates crews through three states does not know that the Colonials off Bradley Lane and the Foursquares near the Chevy Chase Club each have their own peculiar flue geometry. Our crews do, because we have been inside them since long before the national outfits put a billboard on Wisconsin Avenue.
Wendell puts his name and license number on every job. The crew that shows up at your door is background-checked and in uniform, and they will give you a real arrival window and call if it slips. When a Chevy Chase homeowner calls to ask whether a liner needs replacing, the answer they get is not a scripted upsell. It is a level-headed read, backed by camera footage we will show you on the spot. That is how we have built our reputation here, and it is why homeowners near Somerset, Chevy Chase Village, and Martin’s Additions keep our number in the kitchen drawer.
Our Chimney Liner & Rebuild Services in Chevy Chase
Stainless Steel Liner
For Chevy Chase homes where the original terra cotta tile liner has spalled, cracked, or simply was never sized correctly, a stainless steel liner is the standard fix. We pull a DuraFlex or Gelco liner through the existing flue, insulate it properly, and connect it to the appliance with a correctly sized connector. In a 1927 Colonial off Meadow Lane with a furnace venting into an oversized clay flue, the stainless liner stops the condensation problem at its source. Typical cost in Chevy Chase: $3,200 to $5,800 for a single-flue install, depending on the height of the stack and the offset inside the chimney.
Flexible Liner
Flexible liners solve a problem that is common in this housing stock: multi-flue brick chimneys with off-center clay tiles and impossible bends. When the original tile shifted during decades of freeze-thaw cycling, a rigid pipe will not make the turns. A flexible liner will. We use DuraFlex and Olympia Chimney flexible liners on Chevy Chase jobs where the flue is behind a finished wall and we cannot access the full run from the top. Expect to pay $1,800 to $3,400 for a flex liner replacement when the existing tiles are salvageable as a chase.
Liner Replacement
A full liner replacement in Chevy Chase usually means one of two things: the old clay tiles are visibly cracked on the Level 2 camera video, or the flue was never relined when the house switched from coal to gas. Both are common here. If your home off Underwood Street still has its original unlined brick flue venting a gas water heater, that is a code issue and a safety issue. The camera footage will show you exactly why. Full liner replacement in Chevy Chase runs $2,800 to $6,500, and we will give you the number before a single tool comes off the truck.
Partial Rebuild
A partial rebuild addresses the upper portion of the stack: the crown, the top few courses of brick, and the cap. On Chevy Chase’s steep-pitched rooflines, the upper chimney is the first thing to fail. Freeze-thaw cycles open gaps in the old lime mortar, water gets in, and the brick face starts spalling. A partial rebuild above the roofline typically costs $1,500 to $3,800 here, and it often prevents the need for a full rebuild if we catch it before the masonry below the roof has failed. Wendell will tell you plainly if the job can wait another season. Often it can. When it cannot, we will show you why on the video.

Trusted Brands We Service in Chevy Chase
We install and service liners and resurfacing systems from HeatShield, DuraFlex, and Gelco, and we stock the common parts locally so a Chevy Chase job does not stall waiting on a warehouse three states away. HeatShield is a ceramic resurfacing system we use instead of a full stainless liner when the original clay tiles are still structurally sound but have developed minor cracking or surface spalling. For many pre-war Chevy Chase chimneys, it is the right call and costs thousands less than a full liner. We will show you the camera footage and let you make the call with the facts in front of you, always.
Common Chimney Liner & Rebuild Problems We See in Chevy Chase Homes
- Gas inserts venting into oversized clay flues. Homes built by the Chevy Chase Land Company originally burned coal or wood. The flues were sized for that. When someone installs a gas insert without relining, the oversized flue cools the exhaust too fast, and condensation forms. That condensation is acidic. It eats the old clay from the inside out.
- Freeze-thaw cracking of century-old mortar joints and crowns. The DC metro crosses 32°F dozens of times each winter. The original lime mortar in a 1930s chimney was not made for that repeated cycling. When the crown opens and water seeps into the masonry above the smoke chamber, the liner is not the only thing that fails. The brick face starts to spall, and a partial rebuild becomes necessary.
- Mature tree canopy debris and organic clogging. Chevy Chase’s towering oaks and tulip poplars were planted when the Land Company laid out the lots. They are beautiful, and they drop a serious load of leaves, twigs, and debris onto open flue tops every fall. We routinely find chimney caps packed with organic material on homes whose fireplace “looked fine” from inside. That trapped moisture rots the cap and accelerates liner damage.
- Original unlined flues venting modern gas appliances. Some Chevy Chase homes never got a liner at all. The brick flue from 1925 is now venting a high-efficiency gas furnace. The code requires a properly sized, properly listed liner. Without one, moisture condenses directly against the brick and old mortar. We find this on multi-flue chimneys throughout the neighborhood, and it is the single most common reason a Chevy Chase homeowner needs liner replacement.

FAQs - Chimney Liner & Rebuild in Chevy Chase
Do I need to reline my chimney if my Chevy Chase home was built before 1940 and I’ve switched to a gas fireplace?
Almost certainly yes. Most pre-WWII Chevy Chase homes have original clay tile liners sized for wood or coal, not for gas. Gas exhaust is cooler and wetter than wood smoke, so it condenses inside the oversized flue and creates acidic moisture that attacks the old clay. The only way to know for sure is a Level 2 camera inspection, which we will show you in plain English with the footage on the screen. Call (240) 716-5865 and we will check it for you.
What is HeatShield, and why is it popular for old Chevy Chase chimneys?
HeatShield is a ceramic resurfacing system we apply inside an existing flue when the original clay tiles are still structurally sound but show minor cracking, spalling at the surface, or missing mortar joints. It is popular in Chevy Chase because so many of these chimneys are not bad enough for a full stainless liner but are no longer safe or code-compliant to vent as-is. HeatShield coats the flue with a continuous ceramic layer and costs substantially less than a full liner replacement. We use it often on Land Company-era homes, always after showing the homeowner the camera video that justifies it.
Can a cracked chimney crown really cause major damage in Chevy Chase’s climate?
Yes. The DC metro freezes and thaws dozens of times each winter, and a cracked crown lets water into the masonry every time it rains or snows. Chevy Chase gets over 40 inches of rain a year, plus summer humidity that accelerates spalling. Once water gets behind the brick face above the smoke chamber, the liner is no longer the only thing failing. A poured replacement crown is a straightforward fix, and it is the cheapest insurance you will ever buy for a 1930s chimney. Wendell will tell you if your crown can wait or needs doing now.
Why does my chimney liner look like it has tar inside after converting to gas?
What you are seeing is creosote condensation, even though you no longer burn wood. The original oversized flue cools the gas exhaust too quickly, and the moisture and combustion byproducts condense onto the old clay, forming a glaze that looks like tar. We actually saw exactly this on a 1920s Colonial off Western Avenue: third-degree creosote glaze inside the original terra cotta liner because the gas insert was venting into a flue never sized for it. We showed the homeowners the Level 2 camera video, repaired the liner with HeatShield, rebuilt the crown, and that tar glaze is gone. This is not a brush job. It is a reline job.
How often should a Chevy Chase homeowner with an older chimney get a flue inspection?
Once a year, burn or no burn. Chimneys break in the off-season too. Freeze-thaw cycles, summer humidity, and tree-canopy debris all work on your flue whether you ever light a fire. An older Chevy Chase chimney is a structure that needs annual eyes on it, just like your roof. The inspection is quick, and we will show you the camera footage every time, no exceptions. Call (240) 716-5865 and we will get you on the schedule before burning season.
