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 Reading
If you own a brick rowhouse in Reading, your chimney is probably doing a lot more work than you realize. A cracked crown or missing cap on a shared party-wall stack doesn’t just let rain into your flue. It can soak the clay tile, push water into your neighbor’s unit, and quietly compromise the gas furnace, water heater, and fireplace all venting into the same masonry chase. Call Top Hat Chimney at (484) 209-0837 and Wendell will take a straight look at it, tell you what actually needs doing, and quote the job before a single tool comes off the truck.
We’ve worked Reading’s rowhouse blocks long enough to know the century-old stacks off Penn Street, Centre Avenue, and the numbered streets by sight. Many of them still carry the original coal-era clay tile. Most homeowners have no idea which flue serves which appliance. That’s not your fault. The coal-to-gas conversions in the mid-1900s were done cheap, and nobody labeled anything. So when we come out to Reading for a Chimney Cap & Crown job, we don’t guess. We camera the flues, map the chase, and show you the footage before we recommend a dollar of work.
Why Top Hat Chimney Is Reading’s Preferred Chimney Cap & Crown Company
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone half the time you call. You won’t get a call center. You’ll get a live person, any hour of the day or night, and that person will tell you when we can be there, not a computer-generated window that slips without warning. Reading Chimney Cleaning & Sweep homeowners have told us what they ran into with the national outfits: a quote one day, a different number at the door, and a phone that rings into a void when something goes wrong. Wendell puts his name and license number on every job, and he runs into you again at the diner, not just when there’s money on the table.
Every job we do in Reading, from a single-flue cap replacement to Chimney Repair in Reading like a full crown rebuild on a shared party-wall chase, is backed by our 90-Day Done Right Promise in writing. If it’s not right, one call brings the crew back. No argument, no re-quote. We also offer a free second opinion on any written estimate from another chimney company. Bring us a competitor’s number and we’ll look at the job and tell you straight whether it’s fair, inflated, or missing work entirely. Then we’ll price ours so you know exactly what you’re comparing.
We know Reading’s housing stock because we’ve been inside its chimneys. Our crews have worked the apartment conversions near Albright College, the rowhouse blocks around City Park, and the century homes off North Park Road. The stacks in those neighborhoods were built for anthracite coal, with clay tile sized for a coal fire that burned hot and dirty. Modern gas appliances vent cooler, slower, and produce condensation that saturates old tile from the inside. Add a cracked crown at the top and you’ve got a flue that’s failing from both directions. That’s the common Reading story, and we see it every week.
Our Chimney Cap & Crown Services in Reading
Most cap and crown work in Reading falls into a few categories. Here’s what we actually do, along with what we look for on the type of chimneys that dominate this city.
Cap Installation
Reading’s brick rowhouses frequently have a single exterior stack venting three or four appliances: a gas furnace, a water heater, a first-floor our Fireplace Services in Reading fireplace, and sometimes a second-floor fireplace. All of them share one masonry chase and, too often, one undersized or rusted-out cap. We install caps sized for the actual flue configuration, not whatever was on sale at the hardware store. If the chase needs a multi-flue cap, that’s what we quote. Most installations run $250 to $600 depending on chase width, flue count, and whether we need to do any crown prep first. The camera footage comes with the job. Always.

Cap Replacement
Storm winds off Blue Mountain have been known to wrench a loose cap right off its base, and we’ve pulled more than a few rusted Gallo-style caps off Reading chimneys that were doing nothing but collecting bird nests and trapping moisture. A cap that’s rusted through or missing its screen isn’t protecting the flue. It’s doubling the problem. Replacement in Reading typically runs $180 to $450, and we stock common sizes so we’re not pushing you into a four-week backorder from a distributor. If the old cap was installed wrong, we’ll show you that too.

Crown Repair
We spend more time on crowns in Reading than almost any other single job. The valleys between Blue Mountain and South Mountain trap cold air, so crowns here live through freeze-thaw cycles other Pennsylvania towns don’t get. Hairline cracks widen. Water gets in, freezes, and pops the mortar from below. Left alone long enough, the crown spalls and chunks start falling into the flue. Crown repair with proper resurfacing and edge treatment typically runs $400 to $900 depending on chase size and damage extent. A full rebuild with concrete forms and proper overhang runs $800 to $1,400. We’ll tell you which one you actually need, and we’ll tell you if patching will buy you time or waste your money.

Crown Coating
For crowns that are intact but porous, a waterproof crown coating buys real time. Not forever, but years. Reading’s valley fog and storm-driven rain attack exposed mortar, so sealing the crown before it starts spalling is cheaper than rebuilding it after. Coatings run $250 to $500 for a typical rowhouse chase, depending on prep and surface area. We use coatings designed for chimney crowns, not driveway sealer. Your flue doesn’t care how the fire looks. It cares how it breathes. A sealed crown keeps water out of the clay tile so the flue keeps breathing.

Trusted Brands We Service in Reading
We install and service caps and crown systems from Gelco, Olympia Chimney, and Copperfield. These are the brands that hold up to Reading’s freeze-thaw cycles and valley moisture. Unlike a fly-by-night outfit that slaps on whatever’s cheapest, we’ll match the cap system to your specific flue count and appliance mix. If you have a rusting Copperfield cap from the 90s on a three-flue stack, we can source the replacement without making you wait a month. If you have a Gelco repair in Reading for a multi-flue cap that’s been dented by a fallen branch, we can usually handle it on-site. We keep common cap sizes and crown materials stocked for the rowhouse chases that dominate Reading, so turnaround is measured in days, not weeks.
Common Chimney Cap & Crown Problems We See in Reading Homes
Here are the failure modes we walk into on Reading rooftops, week after week.
- Fog and storm moisture saturating uncapped flues. Reading sits in a valley corridor between Blue Mountain and South Mountain, and the cold air drainage off the ridgelines pushes fog and freezing rain directly into open flues. Clay tile soaks it up, spalls, and crumbles from the crown down.
- Crown cracks on shared party-wall stacks. A cracked crown on a shared wall lets water migrate laterally into the neighboring unit. When a homeowner on one side sees a ceiling stain, they usually blame flashing. Often it’s a crown crack two units over, feeding water down a shared chase.
- Missing or rusted caps on unlabeled multi-flue chases. Birds nest in the open flue. Debris blocks the one active furnace flue. Cold reversal pushes exhaust back into the house. Meanwhile the other flues sit open, doing nothing but drinking rainwater.
- Mixed-fuel venting into a single clay flue. Gas furnace and water heater sharing a flue with a crusted-over fireplace liner. The cap is undersized. The crown is cracked. And nobody has looked at this stack in thirty years. That’s not an exception in Reading. It’s the default.
On an early-1900s rowhouse off Penn Street, our crew found a spalled, heavily cracked crown letting valley fog and storm-driven rain pour into a three-flue stack. The original clay-tile liners were crumbling, and a second-floor fireplace flue had been left uncapped for years. We installed a custom multi-flue stainless cap over the shared chase, rebuilt the crown with a waterproof coating, and used a camera inspection to map each flue before the first snow – eliminating the ceiling stain the homeowner had blamed on flashing for two seasons.

What moves the price is flue count, chase width, how much crown repair is needed before a cap can sit properly, and whether we’re dealing with a shared wall. Ages of soot and spalled tile don’t matter to the quote – we’re pricing the fix, not the history. Call (484) 209-0837 for a free estimate.

FAQs - Chimney Cap & Crown in Reading
You usually don’t, without a camera. Our crews run a video scope up each flue and map which one serves the furnace, which serves the water heater, and which serve the fireplaces. Then we cap the active ones properly and close off the dead ones. That’s the only way to do it on a Reading rowhouse stack, because the mid-century coal-to-gas conversions left nothing labeled. Call (484) 209-0837 and we’ll map your chase before we touch a cap.
Yes. A cracked crown on a shared wall lets water run down inside the masonry and migrate laterally. A stain in your neighbor’s ceiling could absolutely be your crown crack, or the reverse. We’ve traced water from a crown crack two units over. Party-wall chimneys don’t respect property lines. Call us for an inspection before you re-roof or patch the wrong thing.
Because patch material doesn’t solve the freeze-thaw problem, and patch material applied over a spalling surface will fail again inside a season or two. A proper crown fix means removing the failing material, resurfacing the crown with the right mix, and adding a proper drip edge so water runs off, not into, the masonry. If a previous patching job has failed, we’ll show you why and quote a real fix, not another bandage.
No. If two gas appliances are venting into the same flue, they’re relying on proper draft and a clear liner. Capping the top without knowing the flue dimensions, liner condition, and whether the appliances are even allowed to share that flue under current code could push exhaust into the house. We inspect first, then decide what cap, if any, is correct. This is one of the most common unsafe configurations we see in Reading’s rowhouse blocks.
It’s safer to cap it now. A missing cap lets rain and fog into the flue all winter, saturating the clay tile and accelerating the exact freeze-thaw spalling that destroys crowns. Birds will nest in an open flue, and a blocked flue in a valley that traps cold air can reverse draft and push exhaust back into the house. Waiting until spring usually turns a $250 cap replacement into a $900 crown rebuild and a stain on the ceiling. Call (484) 209-0837 and we’ll cap it before the next storm cycle.
