Call (240) 716-5865

We’ve worked the tree-lined streets of Chevy Chase long enough to know that your chimney was probably built before World War II, and that the previous owner may never have relined it when the house switched from coal to gas. More on that below. The short version: this isn’t a market where you guess. It’s a market where you look, with a camera, and then decide.

Why Top Hat Chimney Is Chevy Chase’s Preferred Chimney Repair Company

Top Hat Chimney has been answering calls since 1999. Wendell Pike founded this company and still runs it. When you call about chimney repair in Chevy Chase, you get a live person answering the phone, day or night. Not a call center, not a voicemail box that promises a callback. Wendell’s crew is background-checked, uniformed, and they call ahead with a real arrival window. If something slips, we tell you. That’s how we’ve kept working the same neighborhoods for over 29 years.

Chevy Chase homeowners tend to be skeptical of big claims. Fair enough. That’s why every job, including all Chimney Repair work, comes with our 90-Day Done Right Promise in writing. If the repair isn’t holding up, one call brings the crew back at no charge. No hoops. No fine print. We also publish our license number and Wendell puts his name on the work. You’ll likely run into him again at the farmers’ market or on Connecticut Avenue, so he’s not going anywhere.

Here’s what our Chevy Chase customers bring up most: they had a national outfit send a stranger, the price changed at the door, and then the phone went dark when something went wrong. We do the opposite. The number you hear on the phone is the number on the invoice. And we don’t recommend a $6,000 reline unless we can show you the cracked clay tile on camera footage and explain it in plain English. The camera footage and a plain-English verdict, every time, no exceptions.

Our Chimney Repair Services in Chevy Chase

Mortar Repointing

Chevy Chase’s pre-war brick chimneys were built with lime mortar, not the harder Portland cement used after the 1950s. Lime mortar breathes. It also crumbles after a century of DC freeze-thaw cycles crossing 32°F dozens of times each winter. Repointing means raking out the failed joints and tuckpointing fresh mortar that matches the original composition and color. On a 1920s Colonial near Chevy Chase Circle, failing mortar joints are the leading cause of water intrusion into the chimney stack. Typical repointing on a Chevy Chase chimney runs $800-$1,600 depending on stack height and how many faces need work.

Spalling Brick Repair

Spalling is what happens when water soaks into brick, freezes, and pops the face off. You’ll see it as flaking brick faces, chunks of brick on the roof or lawn, or exposed brick interiors where the outer layer has peeled. Chevy Chase’s summer humidity speeds this up once the brick face is compromised. Repair involves cutting out the damaged brick and replacing it with a matched historic brick, then repointing surrounding joints. Spalling repair in Chevy Chase typically runs $450-$1,200 per affected face, and it’s almost always paired with repointing since the two failures share the same root cause: water.

Chimney Waterproofing

Brick is porous. After repointing or rebuilding, we apply a vapor-permeable waterproofing treatment that stops rain from soaking into the masonry while still letting moisture inside the flue escape. This matters on Chevy Chase’s steep-pitched rooflines because water that gets into the brick freezes and expands every winter. Waterproofing alone runs $400-$800 for a typical two-story Chevy Chase chimney, and it’s the single most effective preventative measure after a crown repair. We use commercial-grade sealants that won’t trap moisture and accelerate spalling the way cheap sealers do.

Flashing Repair

Flashing is the metal where the chimney meets the roof. On Chevy Chase’s older Colonials and Tudor Revivals, original flashing was often galvanized steel or even copper, and 40-plus inches of annual rainfall eventually win. Failed step flashing channels water behind the brick, soaks the ceiling, and rots the roof decking. We cut out the old flashing, install new copper or aluminum step and counter flashing, and seal it against the masonry. Flashing repair in Chevy Chase runs $600-$1,400 depending on chimney size and roofline access. On steep pitches, expect scaffold or ladder work on both sides of the stack.

Trusted Brands We Service in Chevy Chase

When a Chevy Chase chimney needs a new liner, crown, or cap, we install and service products we know hold up: HeatShield resurfacing for clay liners that can be saved, DuraFlex stainless steel relines when they can’t, and Olympia Chimney components for caps and chase covers. Wendell’s crew stocks common parts locally, so a repair on a 1930s Foursquare doesn’t stall out waiting on a shipped part. If your system uses Gelco or Famco components, we service those too. Fast turnaround, no ordering whatever the warehouse has on hand and hoping it fits.

Common Chimney Repair Problems We See in Chevy Chase Homes

• Original clay tile flues cracking under freeze-thaw pressure. Homes built by the Chevy Chase Land Company between the 1910s and 1940s almost all have original terra cotta tile liners. Decades of Chevy Chase winters have opened hairline cracks in many of them, and those cracks let flue gases and moisture into the surrounding masonry. You usually can’t see this from the ground. You can see it on camera.
• Undersized gas appliance flues from coal-to-gas conversions. When these homes switched from coal or oil to gas heat, the oversized original flues were often left unrelined. Gas appliances need smaller flues, and the mismatch causes excess draft and condensation that dumps acidic moisture onto the firebox floor. This is a structural mismatch endemic to this specific development era, and it’s the most common reason we recommend relining in Chevy Chase.
• Cracked chimney crowns on steep-pitched rooflines. The crown is the concrete cap at the top of the chimney. When it cracks, water gets behind the brick and runs down the stack. On Chevy Chase’s steep roofs, water that enters at the crown travels fast and spreads wide. Crown repair or replacement runs $500-$1,100 and should be done before the first freeze of the season.
• Organically clogged caps from mature tree canopies. Chevy Chase’s towering oaks and tulip poplars, planted when the Land Company developed the lots, drop heavy leaf and debris loads into open flue tops every fall. Overhanging limbs also accelerate moss and moisture retention on chimney crowns. We routinely find caps packed with organic debris on homes whose owners haven’t swept in years because the fireplace looked fine from inside.
