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 Cap & Crown Across Fort Washington
A cracked chimney crown in Fort Washington rarely announces itself. It shows up months later as a water stain on the living room ceiling, or as efflorescence blooming white and chalky across the brick face. Here’s the direct answer: if you live in Fort Washington and suspect your cap or crown is failing, call (240) 358-4452. We’ll inspect it, show you camera footage of exactly what’s wrong, and give you a flat price before any work begins. No ghosting, no price bump at the door. Wendell Pike founded Top Hat Chimney in 1999, and we’ve been working the riverside neighborhoods of Fort Washington long enough to know what the Potomac does to a chimney crown.

Our Chimney Cap & Crown Services in Fort Washington
Cap Installation
A chimney without a cap in Fort Washington is an open invitation to wind-driven rain, squirrels, and chimney swifts. We install galvanized and stainless caps sized to your flue, including multi-flue caps for the wider masonry chimneys common on colonials in this area. Every installation includes checking the flue for creosote glaze before the cap goes on, because capping a fouled flue just bakes the problem in.
Cap Replacement
When a falling limb from a Tantallon on the Potomac oak takes out your cap, you need a replacement that actually fits. We stock Famco and Copperfield caps in common Fort Washington flue dimensions, so most replacements go in on the same visit. Loose caps that rattle in the wind can damage the crown underneath, so we address both at once rather than patching one and leaving the other to fail.
Crown Repair
The crown is the concrete slab that seals the top of the chimney. In Fort Washington, crowns fail faster than they do in Bowie or Upper Marlboro. Here’s why: the Potomac River shoreline and the creek drainages running through Fort Washington create a high-humidity microclimate that keeps masonry saturated for longer periods. When winter freeze-thaw cycles hit that soaked concrete, it cracks. We repair crowns with proper slope and overhang so water sheds away from the flue instead of pooling against it.
Crown Coating
For crowns that are intact but porous, we apply a Gelco crown coat that seals hairline fractures and prevents the efflorescence and spalling that Fort Washington homeowners see on their chimney faces. This is one of the highest-value services we offer in this area, because the riverside moisture is relentless. A coated crown buys years before a full rebuild is needed.

Trusted Brands We Service in Fort Washington
We’re not parts-swappers. We’re the chimney sweep who shows up at your door, and we install products from Famco, Copperfield, DuraFlex, and HeatShield. These are the brands we’ve trusted for over 29 years. Because so many Fort Washington homes have the same era of masonry chimney, we keep common cap sizes and crown coating materials on the truck. That means less waiting on a second trip when your cap needs replacing or your crown needs sealing.
Common Chimney Cap & Crown Problems We See in Fort Washington Homes
- Wind-driven rain soaking uncapped flues. The Potomac doesn’t blow straight down. It blows sideways. Rain enters uncapped flues at an angle, saturating the smoke chamber and creating third-degree creosote glaze that a standard brush cannot remove. We see this weekly in Fort Washington, and the fix starts with a proper cap.
- Cracked crowns along Piscataway Creek. Homes in the low-lying drainages near Piscataway Creek hold moisture in their crowns longer than any other part of the county. Cracked crowns let water track into the flue liner, causing clay tile spalling that only appears as a ceiling stain around the fireplace chase months later. By then, the repair is bigger than a crown coat.
- Flashing failures on low-pitch split-level roofs. Split-levels with shallow roof slopes let water pool at the chimney base, where flashing meets brick. That pooled water rusts cap legs and corrodes custom caps, especially on streets with heavy tree canopy where debris dams the water flow. We check flashing on every Fort Washington cap and crown job because the two fail together.
- Displaced multi-flue caps after storms. A limb falls, the cap shifts, and suddenly the flue is half-covered. On a Tantallon street, our tech found exactly that: a displaced multi-flue cap after a spring storm sent a limb across the crown. We replaced it with a galvanized Famco cap and sealed the crown with a Gelco crown coat, then verified the smoke chamber for dislodged creosote before the first fall fire. That’s the level of checking we do on every Fort Washington call.

FAQs - Chimney Cap & Crown in Fort Washington
Why does my chimney crown crack so much faster in Fort Washington than my sister’s in Bowie?
Your sister’s chimney in Bowie sits on drier, higher ground. Fort Washington sits in a riverside corridor shaped by the Potomac and Piscataway Creek, where humidity rides the low drainages and keeps masonry saturated for weeks after rain. Saturated concrete plus winter freeze-thaw cycles equals crown cracking at a rate you simply don’t see inland. That’s why annual inspection matters more here than in surrounding areas. Call (240) 358-4452 and we’ll tell you if your crown is still sound or starting to go.
Do I need a cap replacement after every bad storm in Tantallon on the Potomac?
No. Most caps survive most storms. What you need after a severe storm in Tantallon is a quick visual check from the ground: is the cap still seated, or is it tilted or rattling? If a limb actually struck the cap, get it inspected before the next rain. A displaced cap that looks fine from the street can be letting sideways rain into the flue. We’ll come out, check it, and tell you honestly whether it needs replacing or just reseating. Estimates are free.
Can a cracked crown cause a stain on my living room ceiling even if the fireplace works fine?
Yes, and this is one of the most common Fort Washington call-outs we get. Your fireplace can draft, burn, and look completely normal while a cracked crown slowly feeds water into the flue liner and surrounding masonry. The water travels down inside the chase and appears as a ceiling stain months later. By the time you see the stain, the crown crack has been there a while. That’s why we recommend checking the crown annually, not waiting for a visible problem inside the house.
What’s the difference between a standard cap and a custom cap for Fort Washington’s wind patterns?
A standard cap bolts onto the flue tile and does a fine job shedding rain and keeping out animals. A custom cap is built to the exact outside dimensions of your chimney crown, which matters in Fort Washington because our wind comes sideways off the Potomac. A custom cap with the right overhang keeps wind-driven rain from wrapping around the cap edge and into the flue. It also stands up better to the debris, limbs, and raccoons that come with heavy tree canopy in neighborhoods like Tantallon. For most older brick chimneys here, a custom cap with proper overhang will outperform a universal-fit cap.
Will a crown coating stop water from getting into my clay tile flue liner?
If the crown is cracked, no coating alone will fix it. The cracks need to be repaired first, then the coating seals the crown surface and the hairline fractures. On a crown that’s intact but beginning to show efflorescence or minor spalling, a Gelco crown coat can absolutely stop water intrusion before it reaches the flue liner. The key is catching it while the crown is still coatable. Call (240) 358-4452 for a free estimate, and we’ll show you exactly what condition your crown is in before recommending anything.
What Fort Washington Homeowners Should Check Before the First Fire of the Season
Walk outside and look up. Is your cap still seated square on the flue, or has a summer storm shifted it? On the crown, look for white chalky patches, hairline cracks, or pieces of concrete missing at the corners. Inside, check the ceiling around the fireplace chase for any discoloration. If you’re on a wooded street in Tantallon or along Piscataway Creek, check for fallen limbs on the roof. Fort Washington’s wind, humidity, and tree canopy combine to crack crowns and displace caps more aggressively than almost anywhere else in Prince George’s County. If any of that looks off, call (240) 358-4452. We’ll come out, put eyes and a camera on it, and give you a straight answer.
