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.
Gelco Chimney Repair in Reading: What to Know First
We repair Gelco chimney systems throughout Reading, and most jobs are diagnosed and fixed within a week. As an independent Gelco service provider, we charge by the actual repair, not a brand premium. The price Wendell quotes before the first tool comes off the truck is the price on the invoice.
This page is for Reading homeowners whose Gelco chimney or venting system is showing signs of trouble: mortar failing around the unit, a liner that’s pulling loose, spalling brick, flashing that’s letting water run down the chase. If that sounds like your house, call (484) 209-0837. We’ll send someone who has actually worked on Gelco systems in Berks County, not a trainee with a tablet and a script.
How Gelco Products Fail - and How We Fix Them
Gelco made solid chimney components, but nothing survives forever. Here’s what we see on Gelco jobs around Reading, and what we do about it:
- Gelco clay flue liners cracking at the mortar joints. Gelco liners were common in mid-century Berks County homes. The clay itself holds up, but the mortar between sections eventually erodes from years of flue gas condensation. We see it on houses off Centre Avenue and up toward Muhlenberg. The fix is usually HeatShield resurfacing or a DuraFlex stainless liner slipped inside, depending on what the camera shows.
- Gelco chimney caps rusting at the weld points. The cap is the first thing to go. Water gets into the seam where the screen meets the frame, rust spreads, and suddenly you’ve got a cap that’s more hole than metal. We replace with an Olympia or Copperfield cap sized to the Gelco flue, not a generic box-store lid that doesn’t fit right.
- Flashing failure where the Gelco termination meets the roofline. Reading gets real freeze-thaw cycles, and that’s murder on flashing. The metal expands and contracts, the sealant dries out, and water works its way into the chase. We remove the old flashing, inspect the deck, and re-flash with proper step flashing and a real storm collar - not a smear of caulk and a prayer.
- Spalling brick around the Gelco chase. Older Gelco installations in Reading used whatever brick the builder had on hand. If the crown wasn’t poured right, water soaks the brick and freezes. The face pops off. We cut out the damaged brick, match it as close as we can, and then pour a proper crown with a drip edge so it stops happening.
- Weeping mortar joints on the chase exterior. The mortar breaks down before the brick does. Left alone, joints open up and the chase starts breathing water. Tuckpointing fixes it, but only if the real moisture source is addressed first. Otherwise you’re just repointing the same joints again in five years.
Our Gelco Chimney Repair Process
Here’s how a Gelco job goes when you call Top Hat Chimney:
- 1
You call, a person answers. Twenty-four hours a day, seven days a week. Might be Wendell on the other end. You tell us what’s happening, and we schedule a time that works. Inside the county, no trip charge.
- 2
We show up, we look, we show you. The sweep who arrives is background-checked and in uniform. Before anything else, we run a camera down the flue if the problem suggests internal damage. You see the footage. You hear the plain-English verdict from Wendell and his crew. Every time, no exceptions.
- 3
Parts decision. If your Gelco components need replacing, we talk it through. OEM Gelco parts aren’t always available anymore, which is a fact anybody working on these systems has to deal with honestly. Where OEM is available and it’s the right call, we recommend it. Where a quality aftermarket part from DuraFlex, Olympia, or Copperfield does the job better or faster, we tell you that too. No games.
- 4
The repair. We do the work with the same care we’d want on our own chimneys. That means proper materials, clean mortar work, and no shortcuts that’ll hide until next winter.
- 5
The test. Before we leave, we verify the repair. That might mean a smoke test, a water test on flashing, or a re-camera after a liner install. You see the result.
- 6
The promise. Every Gelco repair we do in Reading comes with our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back. No arguments.

Why Reading Homeowners Call Top Hat Chimney for Gelco Work
Because we’ve been doing this since 1999, and Wendell Pike puts his name on every job. Not a franchise. Not a dispatcher in another state. A local owner-operator who grew up out west, learned the trade at Southwestern College, and has spent years working the rowhouses and old brickwork around Reading, including plenty of jobs near Pagoda Hill. If it doesn’t need doing, he’ll be the first one to tell you.
We also know Gelco isn’t the only system in your house. When a repair calls for a DuraFlex liner or a HeatShield resurfacing job, we install and service those brands too. Same upfront pricing. Same guarantee. Same face showing up at your door. Ask anyone on your street.
FAQs
Gelco no longer operates as a standalone manufacturer, so OEM parts are limited to whatever remains in the supply chain. That doesn’t mean your chimney is orphaned. We match what’s needed with equivalent or better components from trusted aftermarket brands like DuraFlex and Olympia, sized correctly to your Gelco flue, and installed the right way.
We can diagnose it and give you the camera evidence you need for a warranty claim. As an independent service provider, we aren’t an authorized warranty agent for Gelco. But we’ll document everything plainly so you have what you need, and we’ll tell you honestly if the repair is even worth claiming versus just fixing it. Call (484) 209-0837 and we’ll take a look.
Most inspections are scheduled within a few days, and repairs usually happen within a week of diagnosis. If it’s urgent - say, a confirmed leak during a wet stretch - let us know when you call and Wendell will do what he can to get someone out sooner.
Depends on what the camera shows. If the flue liner is intact and the chase is structurally sound, repair makes sense. If water has been soaking the chase for a decade and the brick is turning to powder, a rebuild may be the honest call. Wendell will show you the footage and the cost of both paths. If the cheaper repair gets you another ten years, that’s what he’ll recommend. If it doesn’t need doing, he’ll be the first to tell you.
Water keeps working on the mortar, the brick, and the flashing. Freeze-thaw cycles in Berks County accelerate the damage every winter. Small flashing leaks become chase rebuilds. Minor spalling becomes structural. The repair costs more later. If you’ve noticed water stains, loose brick, or a rusting cap, call (484) 209-0837 for an estimate. The inspection is free to schedule, and the quote is the quote.
