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 Repair Across Chevy Chase
Chimney repair in Chevy Chase, MD rarely announces itself until water is already working through your brick. Most calls we take start the same way: a stain on the ceiling after a hard rain, a flake of mortar on the hearth, or a fireplace that used to draw fine and now pushes smoke back into the room. The homes here were built between 1895 and 1945, and the chimneys carry that age in ways that a quick sweep will never reveal. When you call (240) 618-3233, you get Wendell Pike on the line or one of his crew, and we schedule a time that works for you before giving an honest assessment of what you actually need.
Why Top Hat Chimney Is Chevy Chase’s Preferred Chimney Repair Company
Wendell Pike founded Top Hat Chimney in 1999, and he has spent the years since crawling through more Chevy Chase flues than any franchise tech who rotated through the DC metro last spring. Chevy Chase is not a normal service stop. It is a patchwork of separately incorporated municipalities, each with its own building official and permit desk, and we know which side of the line a house falls on before we walk up the driveway. Ask anyone on your street. The camera footage and a plain-English verdict come with every job, no exceptions, and the price you hear on the phone is the number on the invoice.
Chevy Chase customers call us because they have been burned by national outfits before. A stranger shows up, re-quotes at the door, and disappears when the liner leaks a month later. Wendell puts his name on the work. His license number is published. He runs into you again on Saturday at the hardware store. That is the difference, and it is why the 90-Day Done Right Promise is stamped on every job in writing: if it is not done right, one call brings the crew back at no additional cost.
Our Chimney Repair Services in Chevy Chase
Mortar Repointing in Chevy Chase
Chevy Chase’s century-old chimneys were laid with lime-based mortar, which breathes differently than modern Portland cement. Freeze-thaw cycling in January and February pushes water into the joints, it freezes, expands, and pops the mortar loose. Repointing here is not a cosmetic touch-up. We rake out deteriorated joints to a proper depth and pack in a mortar mix matched to the original lime content so the chimney moves the way it was built to. A typical repointing job on a Chevy Chase chimney runs $900 to $2,400 depending on height and joint condition.

Spalling Brick Repair in Chevy Chase
Spalling is what happens when water gets behind the brick face and freezes. The face pops off in flakes and leaves the softer interior exposed. On pre-WWII Chevy Chase homes, this usually shows up first on the chimney cap and the top three to five courses where exposure is worst. We remove the damaged brick, match the replacement as closely as possible to the original Colonial Revival or Tudor palette, and reset it with mortar that keeps future water moving outward instead of inward. Spalling repair in Chevy Chase typically runs $700 to $1,900 per chimney face.

Chimney Waterproofing in Chevy Chase
Waterproofing a chimney in Chevy Chase is not optional if you want the brick to reach its second century. Summer humidity promotes moss and efflorescence on older crowns, and that moisture works into the masonry all season long. We apply a vapor-permeable siloxane treatment that lets the brick breathe while blocking liquid water, not a paint-on sealer that traps moisture and makes spalling worse. Plan on $500 to $1,100 for a full chimney treatment, including crown prep and inspection.

Flashing Repair in Chevy Chase
Flashing is the metal joint where your chimney meets the roof, and it is the most common source of roof leaks in older Chevy Chase homes. The original flashing on homes built between 1895 and 1945 was often copper or galvanized steel, and after eighty-plus years of thermal expansion, it separates at the seams. We cut out the old flashing, install new step and counter flashing, and seal the joint so water never finds its way back under the shingles. Flashing repair in Chevy Chase runs $600 to $1,500 depending on roof pitch and access.
If your chimney needs more than patching, our Chimney Repair team handles full rebuilding as well. A Chevy Chase chimney that has lost its structural integrity above the roofline needs to come down and go back up before it comes through the roof on its own. Rebuilds here run $4,500 to $12,000, and we will always show you the camera footage before we recommend something that big.

Your flue doesn’t care how the fire looks. It cares how it breathes.
Common Chimney Repair Problems We See in Chevy Chase Homes
- Multi-flue historic chimneys that were never relined. Chevy Chase homes built by the Chevy Chase Land Company often have two to four decorative fireplaces that cycled through wood, oil-furnace flue sharing, and gas-log conversions. Each conversion should have included a proper liner swap. Most of the time, that step was skipped, and we find deteriorated clay tile behind brick that looks flawless from the street.
- Freeze-thaw damage in lime mortar. Temperatures in Chevy Chase cross 32°F multiple times per week in winter, and century-old lime-based mortar is especially vulnerable. Water works into the joints, freezes, and expands, and the mortar crumbles from the inside out. Chimneys that sit idle all summer in high humidity weather even worse.
- Third-degree creosote glaze behind gas-log conversions. On a Colonial Revival in Chevy Chase Village, our crew found a third-degree creosote glaze inside a flue that had been converted to gas logs decades ago without relining. The old clay tile was cracked and spalling, and the smoke chamber was coated with tar. We removed the gas log set, mechanically removed the creosote, then installed a DuraFlex stainless steel liner and rebuilt the smoke chamber with HeatShield. The Village permit was part of the job from the start.
- Misdiagnosed liners from handyman inspections. Homeowners attempting DIY repairs or hiring generalists without Level 2 inspection experience get told the tile looks fine because the outside brick looks fine. We routinely find firebox cracks and deteriorated liners behind decorative fireplace facades in Chevy Chase that a flashlight inspection missed by a mile.

FAQs - Chimney Repair in Chevy Chase
A Chevy Chase chimney can look perfect from the street and be failing on the inside. Homes built by the Chevy Chase Land Company between 1895 and 1945 typically have multi-flue brick chimneys that were converted from wood to oil to gas over the decades, often without proper relining. We use a camera to inspect every flue on every job, and the footage shows you exactly what the brick is hiding. Call (240) 618-3233 to schedule an inspection and see the inside of your flue before you spend a dollar on repair.
It depends on your address, which is exactly the kind of answer that frustrates people until they understand the situation. Chevy Chase is a patchwork of separately incorporated municipalities, including Chevy Chase Village, the Town of Chevy Chase, and Martin’s Additions, each with its own building official and permit process entirely separate from Montgomery County’s. A chimney relining job on one block may require a Village permit, while the house next door falls under the County. We check before we quote, and we handle the permit application on jobs that need one. No delays, no surprises at inspection time.
Once a year, burn or no burn. Chimneys break in the off-season too. For an eighty-to-130-year-old Chevy Chase chimney with multiple flues, the annual inspection is not a formality. It is the only way to catch deteriorating clay tile, hidden creosote glaze, and mortar loss before water works its way into your roof deck and ceiling. Wendell has been running his camera through Chevy Chase flues since 1999, and he will tell you plainly when the chimney needs nothing, which is often the case. When it does need work, you will see the evidence yourself.
Third-degree creosote is a hard, tar-like glaze that forms when a flue runs hot and then cools repeatedly without cleaning, and it is a serious fire hazard. In Chevy Chase, we often find it in flues that were converted to gas logs without proper relining, because the old clay tile was already coating with creosote when the gas conversion happened. First-degree creosote is a brush job. Third-degree is a glaze, and it requires mechanical removal, which we do with professional rotary equipment before deciding whether the liner needs replacement. The glaze can be removed. The fireplace can be made safe. But it takes more than a sweep.
Most Chevy Chase homes still have original flashing from construction between 1895 and 1945, and eighty-plus years of thermal expansion, freeze-thaw cycles, and roof replacements have taken their toll. The flashing is the first line of defense against water entering the roof-to-chimney joint, and when it fails, the water travels down into the ceiling, attic insulation, and the chimney masonry itself. Newer homes in surrounding areas have modern flashing that was replaced more recently and designed for current roofing materials. Your Chevy Chase flashing dates to the Coolidge administration. It is not something to ignore. Call (240) 618-3233 for a free flashing evaluation, and we will show you exactly what we find.
