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.

AfterGelco Chimney Liner & Rebuild in Paterson: What to Know First
Gelco chimney liner and rebuild work in Paterson typically runs $1,800 to $4,600 depending on flue height, liner material, and whether masonry rebuild is needed. Most Gelco liner replacements are completed in one day; partial and full rebuilds run two to four days. We’re an independent Gelco service provider, not a factory warranty center, and we quote every job in writing before any work starts.
This page is for Paterson homeowners who own a Gelco liner or firebox, know the brand is in there, and want an honest read on whether to repair or replace. We inspect with a camera, show you the footage, and write the price down. Call (862) 356-5229 and Corrine or a member of the crew will answer directly.
How Gelco Products Fail, and How We Fix Them
- Gelco flexible stainless liners, the 316L alloy series. The weak point on Gelco’s flexible liner most often shows up as a kink or crushed section about two feet below the chimney cap, caused by an installer who pulled the liner through the flue with too much force and crimped it. The symptom is draft loss and smoke rollback into the living room when a fire is lit. We camera-scan to find the crush point, quote a liner replacement in writing, and pull the new liner through with a coupling attached properly, not a yank.
- Gelco gas vent liners in older Paterson row houses near the Great Falls Historic District. These homes have original masonry flues that were never sized for gas appliances. The Gelco gas liner handles the venting, but the surrounding masonry spalls from freeze-thaw cycles, and the damaged brick pushes inward on the liner. What looks like a liner failure is often the masonry squeezing it. Our fix is a partial rebuild of the affected course, then a new Gelco liner sized to the correct diameter and documented before and after.
- Cast-in-place liners and the thimble connection at the furnace flue. When a Gelco liner was inserted without sealing the thimble joint properly, heat and condensation work at the gap and corrosives eat the liner from the outside in. The homeowner doesn’t see it. The camera does. We see this on Paterson jobs where the liner was installed by a generalist who skipped the sealant step. Our rebuild includes pulling the poor section, replacing the thimble, and sealing with high-temperature refractory caulk to the manufacturer’s spec.
- Gelco chimney caps and lock rings that round off. Gelco’s locking cap systems use screws that strip when a previous technician used the wrong size driver. Once the lock ring is rounded, the cap won’t hold, rain gets down the flue, and the liner rusts from the inside. We replace the hardware with the correct stainless screws and a new lock ring, and in Paterson’s wet springs this repair usually happens before the liner itself needs replacing.
- Gelco rigid liner sections at the first flue offset in Victorian-era Paterson chimneys. Older homes with offset flue paths installed Gelco rigid sections that have since separated at the seam. The gap lets flue gas escape into the chimney cavity, so the liner stops doing its one job. The fix is a reconnection with a new connector band and seam seal, verified with a follow-up camera pass. When the offset is too severe, we recommend converting that section to Gelco’s flexible liner with a proper transition fitting.
Our Gelco Chimney Liner & Rebuild Process
We follow the same sequence on every Gelco job in Paterson. No exceptions. Camera first, quote second, work third, in that order, every time.
- 1
Call and live answer. You reach a person at (862) 356-5229, not a voicemail or web form. We ask what the chimney has been doing, schedule the visit, and assign a named technician.
- 2
Camera inspection, NFPA 211 Level 2. We run the camera down the flue, photograph every section, and record the footage. On a Gelco job we look specifically for the brand tags and connector hardware to confirm what was originally installed.
- 3
Written findings and written price. Corrine reviews the footage and writes the scope: liner brand, alloy grade, diameter, length, how many courses of brick if a rebuild is needed, sealant type, and the line-item total. You get this before we touch anything.
- 4
Parts decision: OEM or equivalent quality. Gelco parts are ordered when they are available and when staying with OEM keeps the warranty intact. Where a quality aftermarket part from DuraFlex or HeatShield performs identically for less money, we offer both and show the cost difference on paper. You choose.
- 5
The liner work and masonry. Old liner comes out, flue is prepped, new liner goes in with the correct couplings and lock rings, thimble sealed, cap replaced. If a rebuild is part of the scope, we cut out the failed brick and relay it with the correct mortar mix for Paterson’s freeze-thaw cycles.
- 6
Post-work camera pass and documented record. We run the camera again, show you the before and after on the same screen, and hand over a written warranty under the Haven Standard. Clause 4 requires the photo record on every visit. You keep that record.

What moves the price: flue count (Paterson Victorian-era homes often have two), liner diameter, roof pitch and access, and whether the existing Gelco hardware is reusable.

Why Paterson Homeowners Call Level Two Chimney Paterson for Gelco Work

Corrine Halstead has been cleaning and lining chimneys for close to eighteen years. Her crew has worked steadily across Paterson, including a long run of older row houses near the Great Falls Historic District where the original masonry makes every liner job slightly different from the last.

We’ve completed over 38,000 chimney inspections and cleanings since 2009. Every single one got a written price before work started and a documented record after it was finished.
FAQs
In most cases, no, provided the replacement liner meets the same UL listing and diameter spec as the original Gelco part. We keep the documentation and photo record on file under Haven Standard Clause 4 so you have proof the work was done to code. We are an independent Gelco service provider, not an authorized warranty center, so we will tell you plainly when a repair can be done under warranty and when it cannot. Call (862) 356-5229 and we’ll walk through it with you.
You know when the camera shows a separation, crush, rust-through, or a gap at the thimble connection, and you see the footage yourself. Symptoms like smoke rollback or a melting smell are reasons to inspect, not proof to replace. We never recommend a liner replacement without camera evidence, and we show you that evidence before we quote anything.
A single-flue liner replacement is usually a one-day job, including the post-work camera pass and clean-up. Partial and full rebuilds run two to four days depending on weather and masonry access. We schedule Paterson jobs in writing with a named technician and a text when we’re on the way.
Sometimes. A separated seam can be reconnected. A rounded lock ring can be replaced with new stainless hardware. A sealed thimble can be resealed. When the repair is safe and will hold, we recommend it and write it up. When the steel is rusted through or crushed, we say so plainly and show you the section on the footage. We will not rebuild a liner that only needs a connection.
Yes. We install and service DuraFlex and HeatShield liners and parts in addition to Gelco. The truck carries all three brands, which means we aren’t waiting on a supplier to finish a Paterson job, and we can show you price differences between them before you commit. If a written quote from another company lists a different brand, bring it in for a free second opinion.
Call (862) 356-5229 to schedule a camera inspection. We’ll show you what’s actually in your chimney, write down what it costs, and do the work in that order.
