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.

AfterFast, Reliable Chimney Cap & Crown Across Chevy Chase
Chimney cap and crown work in Chevy Chase comes down to one thing: stopping water before it gets behind your brick. Most calls we run in Chevy Chase are for crowns that have spalled apart over eighty or a hundred winters, or caps that were never sized right for a multi-flue chimney in the first place. We’ve been inside those chimneys. We know what they look like behind the plaster. Call (240) 618-3233 and Wendell or his crew will give you a straight answer, a camera inspection, and a price before any tool comes off the truck.
Why Top Hat Chimney Is Chevy Chase’s Preferred Chimney Cap & Crown Company
Top Hat Chimney has been at this since 1999. Wendell Pike puts his name on the work, publishes his license number, and backs every job with a 90-Day Done Right Promise in writing. If it’s not right, one call brings him back. No fine print. That matters in Chevy Chase, where half the chimneys we see are original to homes built before 1945 and the other half have had years of well-intentioned but wrong repairs.
Chevy Chase homeowners call us because they’ve already been burned by someone who quoted one price on the phone and changed it at the door. We don’t work that way. The number you hear on the phone is the number on the invoice. Calls are answered by a live person around the clock, and it’s often Wendell himself. Background-checked, uniformed techs show up with a real arrival window and call if that window slips.
Ask anyone on your street. We’ve worked the same communities for over 29 years. We run into our customers on Saturday at the hardware store, not the other side of the country.
Our Chimney Cap & Crown Services in Chevy Chase
Chevy Chase homes are different. Ten fireplaces on one block, twelve on the next. The work requires patience and a willingness to look at the whole chimney, not just the piece that’s leaking. Here’s what we do most in Chevy Chase.
Cap Installation
New cap installation in Chevy Chase almost always means addressing multiple flues on a single masonry chimney. A standard cap from a big-box shelf won’t cover the footprint of a 1920s Tudor stack with three clay tile flues side by side. We size the cap to the crown’s actual dimensions, including any decorative corbeling that protrudes past the masonry face. The cap has to shed water beyond that corbeling or water runs straight down the brick face and soaks the attic framing.
Cap Replacement
Replacement caps on Chevy Chase chimneys are rarely a straight swap. The old cap was often a generic galvanized unit that never matched the home’s original copper flashings or the brick color. We replace it with something that actually fits, typically from Famco or Copperfield, which both build caps for historic multi-flue applications. Before we set a new cap, we check the liner condition. A cap traps moisture if the clay tile is already cracked and spalling, and then you’ve accelerated a problem you thought you fixed.
Crown Repair
This is the single most common job we do in Chevy Chase. The original crowns on these homes were poured with lime-based mortar over a hundred years ago. Freeze-thaw cycles in January and February, when temperatures cross 32°F multiple times a week, pop that mortar apart joint by joint. We rebuild the crown with a proper slope away from the flue tiles so water never pools against them, then seal with a CrownCoat or similar system. No caulk slapped over cracks. That’s a temporary patch that fails by the next winter.
Crown Coating
Crown coating works when the crown’s structural shape is still intact but the surface has hairline cracking and efflorescence from repeated wetting. On a Chevy Chase brick chimney, we use a flexible crown coating that can move with the masonry through freeze-thaw cycles without splitting. This is the right fix when the crown just needs waterproofing, not a full teardown. Our camera tells us which one you need. You see the same footage we see.

Trusted Brands We Service in Chevy Chase
We install and service chimney caps and crown systems from Famco, Copperfield, and Gelco. These are the brands that hold up on Chevy Chase’s century-old masonry, not the thin galvanized caps that rust out in five years. We keep common Chevy Chase sizes and hardware on the truck, which means most cap replacements and crown repairs are done in a single visit. For custom caps on unusual chimney footprints or decorative corbeling, we measure on site, order from the manufacturer, and come back for a second trip to install. You’ll know the schedule before we leave the first time.
Common Chimney Cap & Crown Problems We See in Chevy Chase Homes
- Spalled crowns on original 1920s chimneys. The lime mortar breaks down under decades of freeze-thaw, and water seeps between flue tiles into attic framing. The damage stays invisible behind plaster until a ceiling stain shows up.
- Mismatched caps on multi-flue stacks. A generic cap that doesn’t cover all flues or doesn’t clear the corbeling lets rain run down the brick inside the chimney chase. Draft problems and rust staining follow.
- Gas-log conversions without proper relining. Many Chevy Chase fireplaces switched from wood to gas decades ago and vent into flues that were never sized or relined for that use. Adding a cap without checking liner condition can trap acidic condensation and rot the clay tile faster.
- Deteriorated mortar joints between cap and flue. When the joint where the cap meets the flue tiles loses mortar, water enters exactly where you can’t see it. The first sign is often a damp smell in the firebox after rain, not a visible leak.

FAQs - Chimney Cap & Crown in Chevy Chase
It depends on which Chevy Chase municipality your home falls under. The area contains several separately incorporated municipalities: Chevy Chase Village, the Town of Chevy Chase, Martin’s Additions, and others. Each has its own building official and permit process entirely separate from Montgomery County’s. A crown rebuild on one block may require a Village permit; the house next door falls under the County. We handle the determination for you before work begins, and we never start a job that needs a permit without one in hand. Call (240) 618-3233 and we’ll tell you exactly what your address requires.
Because the repair was probably a patch job. Chevy Chase chimneys from the 1920s were built with lime-based mortar, which moves differently than modern Portland cement. If someone slapped a cement patch over the crown, it cracks at the joint line within a year or two because the two materials expand and contract at different rates through DC’s winter freeze-thaw cycles. A proper fix means rebuilding the crown with compatible mortar, sloping it away from the flues, and sealing it with a flexible crown coating. We’ll show you the before and after on camera so you know it was done right.
No, and we’d tell you not to. Capping an unused flue without checking the liner condition can trap moisture inside the flue and accelerate deterioration of already-fragile clay tile. That’s exactly how some Chevy Chase homeowners end up needing a full liner install when a simple inspection first would have shown the flue was fine. Our camera goes down first, every time. We show you the footage, and we tell you plainly if the cap is all you need or if the liner needs attention too. For an honest look at your flue, call (240) 618-3233.
A custom cap sized to the crown’s full footprint, including clearance past the corbeling. A stock multi-flue cap often leaves the decorative brick corbeling exposed to direct rain, and that’s where water saturates the masonry and freezes. Copperfield and Famco both build caps for this exact scenario. We measure on site, account for every flue and every inch of protruding brick, and install a cap that sheds water beyond the corbeling like the original design intended. You’ll get photos of the cap before install so you know what’s coming.
If you smell smoke inside the house when the fireplace runs, or the fire won’t draw at all, and the cap is new or recently changed, the cap is a likely culprit. Chevy Chase chimneys with multiple flues and tall stacks need caps with proper mesh sizes and clearances. A cap that’s too restrictive starves the fire of air; a cap with the wrong screen density traps combustion byproducts and sends them back down into the room. We diagnose it with a camera and a draft test. One visit usually tells you exactly what’s wrong. Call (240) 618-3233 for a same-week appointment in Chevy Chase.
