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 Mohnton
Most cap and crown problems in Mohnton start the same way: water gets where it shouldn’t, and a chimney that was built for coal in 1910 quietly fails. We fix it right, and you’ll know exactly what was wrong because we document everything with a camera before we touch a single brick. Top Hat Chimney has served Berks County since 1999, and Wendell Pike answers the phone himself. Call (484) 209-0837 for a free estimate with no trip charge inside the county.
A properly installed chimney cap and a sound crown are the difference between a chimney that breathes and one that slowly drowns from the top down. In Mohnton’s older homes, we see it every week. You don’t need a national chain that sends a stranger with a binder of add-ons. You need someone who knows why a three-flue coal-era stack behaves differently than a single-flue ranch chimney. We know because we’ve been on the roofs here, in the rain, in January. That’s the job.
Why Top Hat Chimney Is Mohnton’s Preferred Chimney Cap & Crown Company
We’re not a franchise that rotated in last spring. Wendell Pike founded this company in 1999 and he still climbs ladders. Call the office at any hour and a live person answers. That person may be Wendell, and he’ll tell you plainly whether you need a crown rebuild this year or whether it can safely wait. You’ll get a number before any tool comes off the truck, and the invoice matches it. That’s how we’ve kept our name clean in a town where you run into your sweep at the grocery store.
Mohnton homeowners have told us the same story more times than we can count: a big national outfit quoted one price over the phone, then a technician stood in the living room and tripled it. We answer that by putting the 90-Day Done Right Promise in writing on every job. If the work isn’t right, one call brings Wendell back at no cost. No fine print, no supervisor gauntlet. Just the same sweep who was on your roof, back to make it right. And we publish our license number because your neighbor is going to ask about us anyway.
Our Chimney Cap & Crown Services in Mohnton
Cap Installation
A cap isn’t just a hat for your chimney; it’s the first line of defense against rain, snow, and the animals that find an open flue awfully inviting in a Berks County winter. In Mohnton, we install caps sized to your actual flue dimensions, not a one-size-fits-most piece that slides around in the wind. A loose cap rattles, shifts, and eventually lets water in around the edges anyway. We measure, we fit, we seal it properly, and we show you camera footage of the finished job from the top of the stack. For multi-flue chimneys, which are common here, we recommend a multi-flue cap that covers the entire crown and isolates each flue so they don’t share one leaky opening.
Cap Replacement
Rust never sleeps in southeastern Pennsylvania. A galvanized cap from twenty years ago is likely a lacework of pinholes by now, and a stainless cap installed wrong is just as useless. In Mohnton’s freeze-thaw climate, an old cap that’s corroded through lets snow melt straight down the flue, then refreezes against the clay tile. That’s how tiles start to crack in spirals. We replace caps with quality hardware from Gelco, Olympia Chimney, and Copperfield, and we’ll tell you honestly if the old cap could be cleaned and resealed instead of replaced. The camera verdict is yours to keep.
Crown Repair
This is the one everyone misses because the damage starts on top where nobody looks. A chimney crown is the concrete slab that sits over the top courses of brick, shedding water away from the flue. When it’s flat, cracked, or missing a drip edge, water runs down the brick face, freezes, and pops the mortar joints open. On Mohnton’s pre-1940 homes, crowns were often poured with a mix too sand-heavy to survive decades of freeze-thaw cycling. We rebuild crowns with proper slope, reinforcement, and drip edge, then seal them so water sheds away from every flue. A cracked crown is not cosmetic. It is a slow structural failure, and it doesn’t get cheaper to fix by waiting.
Crown Coating
When the crown is structurally sound but showing surface cracks and pitting, a quality crown coating buys years of protection without a full tear-out. We use breathable, weatherproof crown sealants that flex with temperature swings instead of cracking against them, which matters a lot in a borough where January daytime thaws and nighttime freezes happen weekly. The key is prep: loose material has to go, cracks get filled, and the surface gets a proper bond. Skip the prep and you’re painting over rust. We don’t skip it, and the camera footage shows the before and after.

We install and service caps, crowns, and flue hardware from Gelco, Olympia Chimney, Famco, and Copperfield, which means we can match your existing chimney setup rather than forcing a universal part. For older Mohnton chimneys with unusual flue spacing or a mix of tile shapes, a Custom Cap built to your measurements is often the difference between a dry flue and a slow leak. We keep common replacement parts stocked so scheduling a follow-up in Mohnton doesn’t turn into a two-week wait. When your stack needs something specific, we order it, track it, and call you when it’s in hand.
Common Chimney Cap & Crown Problems We See in Mohnton Homes
- Freeze-thaw crown cracking on century-old mortar. Berks County temperatures wobble across 32 degrees all winter long, and every cycle opens hairline cracks a little wider. Once water gets behind the flue liner, spalling accelerates before anyone sees damage from the ground. By the time it’s visible from the sidewalk, the crown is usually gone.
- Coal-era flues capped with improvised junk. We find unused flues sealed with sheet metal, flattened coffee cans, and once a piece of plywood. These trap moisture and create hidden backdraft paths that push carbon monoxide in when another flue is actively drafting. That’s a real hazard, not a hypothetical.
- Flat crowns on multi-flue stacks. A single flat slab over two or three flues lacks a drip edge, so water sheets down the chimney face, erodes the mortar beds, and eventually spalls whole brick faces on the weather side. Mohnton’s older masonry chimneys need a crown that directs water away from every flue, not just the one in use.
- Mismatched flue sizing for modern wood inserts. A coal-era flue was built huge to vent a coal furnace. Now a wood insert gets shoved in, and the flue is oversized, the draft is weak, and creosote builds up fast. The cap alone can’t fix draft, but installing a properly sized cap that reduces the opening can help stabilize the draft enough to see on the first fire. We’ll tell you before we sell you anything whether the flue needs a liner, not just a cap.

FAQs - Chimney Cap & Crown in Mohnton
How do I know if the unused flue on my Mohnton chimney is causing a draft or moisture problem?
The clearest sign is a stale, smoky smell that appears when you light a fire in another flue, combined with damp spots or efflorescence on the chimney face. We inspect every flue on a stack with a camera, even the ones you think are abandoned, because a blocked or improvised cap on an unused flue can backdraft into the home. If we find moisture trapped in a sealed flue or a draft reversal on camera, we’ll show you the footage and explain whether a proper cap or a flue seal solves it. Call (484) 209-0837 to schedule an inspection; estimates are free.
Do I need a separate cap for each flue in my multi-flue coal-era chimney?
Not necessarily. A properly installed multi-flue cap covers the entire crown and isolates each flue with its own opening, which usually performs better than separate caps that can shift and leak around the edges. What matters in Mohnton is that each flue is either capped properly or sealed properly, not left with a scrap of rusted metal and hope. We measure your crown and flue spacing and tell you which option costs less and lasts longer.
My chimney crown is cracked but not leaking yet - why fix it now?
Because a crack that isn’t leaking in October will be leaking by February. Freeze-thaw cycling across the 32-degree mark forces water into every hairline crack, and each freeze widens it. The crown is the lid on a chimney; once it fails, water gets behind the flue liner and accelerates damage you can’t see. Repairing a crown now costs a fraction of a full rebuild plus liner replacement later. We’ll show you camera footage of the cracks and let you decide with your own eyes. Call (484) 209-0837 for a free estimate with no trip charge inside the county.
Can a chimney cap improve draft for my wood insert on an old coal flue?
Yes, in many cases a properly sized cap stabilizes draft enough to see it on the first fire. But the cap isn’t the whole fix. If your coal-era flue is oversized, draft stays weak no matter how tight the cap. We installed a cap on a wood insert situation in Mohnton where the real improvement came from pairing the cap with a properly sized flue opening, and the homeowner saw the difference on camera. If your insert is struggling, call (484) 209-0837 and we’ll inspect the flue sizing before recommending anything.
Do you install custom caps for unusual flue spacing on older Mohnton chimneys?
Yes, we do. Older Mohnton homes often have two or three flues spaced irregularly under a single crown, and standard caps don’t fit. We order custom-built caps to your exact measurements, usually in steel from Copperfield or Famco, and install them so every flue is isolated and protected. The process takes a little longer than a stock cap, but a custom cap is often the only way to keep water out of a coal-era stack. Call (484) 209-0837 and we’ll measure it up for a free quote.
