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.

Why Top Hat Chimney Is Adelphi’s Preferred Chimney Cap & Crown Company
We’ve been working on Adelphi chimneys long enough to know what the 1960s colonials off Metzerott Road have in common with the Cape Cods near Adelphi Road and the split-levels in Buck Lodge: original clay tile liners, mortar crowns that have been freezing and thawing for half a century, and in too many cases, not a single documented inspection since the last home purchase. When a Chimney Cap & Crown in Adelphi job comes in, Wendell doesn’t guess. He looks. Camera first, then a plain-English verdict.
Adelphi homeowners don’t need a national outfit that sends a stranger with a tablet and a quote that doubles at the door. They need a name they can verify, a license number they can check, and a crew that will actually come back if something isn’t right. That’s the whole reason Top Hat Chimney exists. Wendell started this company in 1999 and he still puts his own name on the work. The 90-Day Done Right Promise is in writing on every job, including Chimney Cap & Crown work. If it’s not right, one call brings him back.

Our Chimney Cap & Crown Services in Adelphi
Cap Installation
Most Adelphi homes built in the 1950s and 1960s either never had a proper cap or have one that’s rusted through. Rain gets straight down the flue, and in the UMD rental corridor it’s common to find squirrel nests and bird debris packed against the smoke shelf. We install galvanized, stainless, and copper caps sized to your flue, including custom-fabricated options when the flue is an unusual dimension. A standard single-flue cap installation in Adelphi typically runs $250 to $450.
Cap Replacement
If your existing cap is rusted, bent, or was installed by someone who guessed at the size, we replace it. Bent caps restrict draft. Undersized caps create backpressure, which pushes smoke and carbon monoxide into living space. Oversized caps catch wind and come loose in storms. We measure, match, and secure. Replacement in Adelphi generally costs $300 to $600 depending on flue size and material.
Crown Repair
This is where we earn our keep in Adelphi. The mid-Atlantic freeze-thaw cycle is brutal on mortar crowns. Water gets into hairline cracks, freezes, expands, and spalls the crown apart piece by piece over the years. We see it constantly on original crowns from the 1960s and early 1970s. Small cracks can often be repaired rather than fully rebuilt. Crown repair in Adelphi typically runs $350 to $700, and we’ll tell you honestly if a spot repair will hold or if the crown needs a full rebuild.
Crown Coating
When a crown still has structural integrity but is porous and wicking moisture, we coat it with Gelco crown sealer rather than tearing it out. This seals the surface, fills small voids, and buys years of service for a fraction of a rebuild. We use Gelco because it flexes with temperature swings, which matters in a place like Adelphi where January can be twelve degrees one week and fifty the next. Crown coating typically runs $300 to $500 in Adelphi.

Trusted Brands We Service in Adelphi
We stock and install caps and crowns from Copperfield, Famco, and Gelco. If you have an existing Copperfield multi-flue cap that’s seen better days, we can match it. If you need a Famco cap for an odd-sized flue, we can usually get it same-week. The point of stocking real brands is simple: when we tell you what your Adelphi chimney needs, we can put the exact part in your hands and show you the manufacturer’s spec. No mystery components. No “trust us.” You see the part, you see the invoice, and the price doesn’t change at the door.
Common Chimney Cap & Crown Problems We See in Adelphi Homes
- Freeze-thaw crown spalling: Adelphi sits in a classic mid-Atlantic freeze-thaw belt. Winter days above freezing let water soak into crown mortar, and the next hard freeze pops it apart. Over 50 years, this leaves crowns that look like a crumbling cookie and channel water straight into the flue.
- Missing caps on unlined flues: Many original Adelphi chimneys were built without any cap at all. Rain falls straight down the clay tile liner, soaking the masonry from the inside. In rented properties near the University of Maryland, damage compounds for years before anyone notices.
- Oil-to-gas furnace flues never relined: When Adelphi homeowners converted from oil to high-efficiency gas, most never touched the chimney. The old clay tile flue is massively oversized for a modern gas appliance, so exhaust cools too fast and condenses. That acidic condensate eats the damper, the crown, and the cap from the inside out.
- Squirrel and bird intrusion through rusted caps: A rusted-through cap is an open doorway. We’ve pulled nests, dead birds, and several pounds of acorns out of Adelphi chimneys that hadn’t been touched since a home inspection a decade earlier.

FAQs - Chimney Cap & Crown in Adelphi
Every year, burn or no burn. A 1960s Cape Cod in Adelphi has original mortar that’s now sixty-plus years old, and the freeze-thaw cycle doesn’t take a year off. One annual look at the crown and cap catches spalling and loose caps before water gets into the flue. Call (240) 618-3233 to schedule Adelphi Chimney Cleaning & Sweep. It’s the cheapest insurance a chimney can get.
The cap is rarely the first problem in a neglected Adelphi rental. The flue is. Creosote buildup and cracked clay tile liners don’t fix themselves with a new cap on top. We run a Level 2 camera scan before quoting anything, so you see exactly what the flue looks like. If the liner’s shot, we’ll tell you and quote it. If it’s fine, we’ll cap and sweep and not sell you a liner you don’t need. Call (240) 618-3233 and we’ll put eyes on it.
A multi-flue cap covers two or more flues under a single hood, which makes sense when the flues are close together and share a crown. Separate caps go on each flue individually. On a 1960s split-level in Adelphi with two flues side by side, a Copperfield multi-flue cap usually gives cleaner draft and better weather protection than two singles fighting for space on a narrow crown. We’ll show you both options and the price difference before you decide.
Yes, if the crown still has structural integrity. Near Langley Park we see a lot of crowns that are porous and weeping but not yet broken apart. Gelco crown coating seals the surface and buys years. If the crown has already spalled into chunks, coating won’t save it and we won’t pretend it will. We’ll show you the condition with the camera and let you decide. Estimates are free at (240) 618-3233.
A rusted-shut damper plus creosote smell usually points to water getting down the flue for a long time. In an Adelphi colonial with original clay tile, that’s almost always a failed crown or missing cap letting rain in, combined with years of creosote that’s now damp and off-gassing. The fix starts with the crown and cap, but the flue needs a camera scan to see what damage the water has done. Call (240) 618-3233 and we’ll get you a straight answer.
