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 Cleaning & Sweep in Easton: What to Know First
We provide independent Gelco chimney cleaning and sweep service in Easton, with most Level 1 and Level 2 inspections completed in a single visit and priced upfront before we start. A standard Gelco sweep runs $189 to $279 depending on creosote buildup and accessibility; we do not quote low to get in the door, then discover “surprise” problems. This page is for Gelco owners in Easton’s older neighborhoods - the colonials near the Delaware Canal, the stone homes in College Hill, the post-war capes in Wilson - who want the flue inspected, the creosote out, and an honest verdict on whether anything else needs attention. Call (610) 756-1504 and a live person answers, 24 hours a day.
How Gelco Products Fail - and How We Fix Them
- Gelco chimney cap mesh corrosion in Easton’s wet winters. The Gelco Pre-Fab series caps use galvanized mesh that holds up fine in dry climates but corrodes faster here where Delaware River humidity meets freeze-thaw cycles. We see this on homes south of downtown, where the cap mesh has rusted through after eight to ten years instead of the fifteen you’d expect inland. We replace with stainless or copper mesh from Copperfield, matched to the Gelco base dimensions, and document the before-and-after with photos.
- Gelco Multi-Flue cap seal failure causing water streaks on the smoke chamber. The Multi-Flue line’s silicone bead seal degrades from the top down when leaves accumulate in the valleys between flues, which happens every October in Easton’s mature-tree neighborhoods. Water gets behind the cap, runs the flue wall, and mixes with creosote into a corrosive sludge. During sweep, we pull the cap, clean the mating surface, and re-bed with high-temp sealant rated for Gelco’s expansion specs.
- Gelco Lyemance damper stuck open from creosote glazing. The Lyemance top-sealing damper seals tight when new, but Easton homeowners who burn green hardwood (oak and maple are common here) get stage-three glazed creosote that gums the cable guide. The damper hangs open, bleeding heat all winter. We do not just free it and leave; we remove the assembly, ultrasonic-clean the mechanism, and re-set cable tension to Gelco’s 3/16-inch spec so it seals properly.
- Gelco stainless liner creosote bridging in slow-drafting flues. Gelco’s 316Ti flex liner handles corrosive flue gases well, but in Easton’s tight-sited homes with exterior chimneys on the north wall, the liner runs cold and creosote bridges across the corrugations faster than on south-facing exposures. We use rotary poly brushing sized to the exact Gelco liner diameter - never a generic oversize brush that scores the Ti surface - and verify draft with a manometer before we leave.
- Gelco chase cover corner rust-through at the drip edge. The Gelco factory chase cover has a 90-degree fold at the drip edge that traps water; in Easton, where road salt aerosol drifts in from Route 22 and 611, we’ve seen rust-through at year twelve consistently. We fabricate a replacement with a hemmed drip edge from Copperfield stock, no seam at the stress point, and flash it to the existing Gelco chase with a photo-documented water test.
Our Gelco Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, asks what you’re burning, how often, and whether you’ve noticed draft changes or odors. We book a window and send a confirmation text.
- 2
Arrival and protection. Our technician arrives in a marked truck, uniformed, background-checked. Floor runners from the door to the hearth, drop cloths, HEPA vacuum. We inspect the Gelco cap, damper, and visible liner terminus before touching tools.
- 3
Level 1 or Level 2 inspection per NFPA 211. Level 1 for annual maintenance with no changes. Level 2 if you’ve had a chimney fire, changed appliances, or bought the home. We run a chimney camera on every Gelco job - the camera head fits Gelco’s 6-inch and 8-inch liner profiles without snagging - and you watch the screen with us.
- 4
Sweep and mechanical cleaning. Rotary poly brushes for Gelco liners, hand brushes for smoke chamber and firebox. We remove the Gelco Lyemance damper if fitted and clean it separately. Creosote goes into a sealed vacuum, not your ash dump.
- 5
Verdict and documentation. Photos of what we found, what we did, and what (if anything) needs future attention. If the flue is clear and the mortar is sound, that’s all the good news you need. Written report emailed before we leave.
- 6
Cleanup, pricing, guarantee. We pack out, you inspect the space, you pay the number we quoted. Every Gelco job carries our 90-Day Done Right Promise - in writing, no arguing.

Why Easton Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been sweeping chimneys in Easton since 1984. Russell Haines learned the trade hands-on at Los Angeles Trade-Technical College, then spent decades in the field before starting Hearthstone. He and our crew know Gelco’s product line because we’ve serviced it in local homes for years - the Pre-Fab caps on the ranch houses near Palmer Township, the Multi-Flue setups on the duplexes along Northampton Street, the Lyemance dampers in the restored colonials.
We are not a chain, and we are not a one-truck operator who might answer the phone next year. Our 90-Day Done Right Promise is backed in writing. Our technicians are background-checked, uniformed, and carry the professional-grade brands that work with Gelco systems - DuraFlex liners, HeatShield refractory, Copperfield and Famco components - so we are not ordering parts and making you wait. The price we quote is the price on the invoice. Done right - and we stand behind it.
FAQs
No. As an independent Gelco service provider, we use warranty-safe practices and OEM-compatible parts; the warranty covers manufacturing defects, not who sweeps the flue. If your Gelco liner or cap is under warranty and we find a defect during inspection, we document it with photos and note it in your report so you have evidence for a claim. Call (610) 756-1504 and we’ll check your install date against Gelco’s coverage terms.
We stock common Gelco replacement parts - Lyemance damper cables, Pre-Fab cap bases, Multi-Flue seal kits - and source from Gelco distributors when OEM is the right choice. For mesh and chase cover fabrications, we use Copperfield and Famco materials that meet or exceed Gelco specs, often with better corrosion resistance for Easton’s climate. We tell you which we’re using and why before we order.
The camera tells the story. During every Level 2 inspection, we run a camera through your Gelco flue and show you the footage. Glazed creosote, cracked liner segments, or deteriorated mortar are visible and measurable. If it is safe to sweep and monitor, we say so. If it needs repair now, we explain exactly why and show you the photo. Nothing is recommended without evidence you can see. Call (610) 756-1504 for a free camera inspection.
Once per burning season for regular use, per NFPA 211. In Easton, where many Gelco systems serve as primary heat sources from November through March, that means annual. If you burn unseasoned hardwood, which is common in the Lehigh Valley, inspect mid-season - glazed creosote can form in as few as 50 burns. We keep a thermos of black coffee on the truck and say the best part of the job is handing a customer a clean sweep report and watching them actually breathe easier.
Creosote accumulates, draft degrades, and the risk of chimney fire or carbon monoxide spillage increases. Gelco’s stainless liners resist corrosion but do not prevent creosote buildup; a blocked flue is a blocked flue regardless of brand. The repair cost after a chimney fire - liner replacement, smoke chamber parge, possible framing damage - runs into thousands. A sweep costs a fraction of that. Call (610) 756-1504 for an exact quote; estimates are free.
