How Gelco Products Fail - and How We Fix Them

We’ve worked on enough Gelco systems in Haverhill’s older neighborhoods - particularly around Washington Square and the Bradford historic district - to know where these products tend to show wear. Here’s what we find:

• Gelco Stainless Steel Chimney Liners (Model L and Model S series): The Model L’s 316Ti alloy handles Haverhill’s freeze-thaw cycles well, but we’ve seen premature weld-seam separation at the flex-to-rigid transition when the original installer skipped the Gelco-specified support plate. The Model S, built for oil and gas, corrodes at the waterline if the appliance runs cold-start for months. We cut back to sound metal, install a proper Gelco support or a DuraFlex equivalent from our Haven buying network, and pressure-test before we leave.
• Gelco Multi-Flue Chimney Caps (Premier and Builder series): The Premier’s 24-gauge lid holds up, but the mesh sides on early production runs (pre-2018) fatigue at the corners where Haverhill’s wet snow loads sit. The Builder series uses thinner stock that dents and diverts water toward the flue. We source OEM Gelco replacement mesh or upgrade to a heavier-gauge aftermarket cap from Olympia Chimney, depending on what the customer wants to spend.
• Gelco Chimney Crowns (pour-in-place and precast): Gelco’s crown mix is decent, but we’ve found it bonds poorly to existing brick that’s been saturated by Haverhill’s March nor’easters. The result: surface cracking within two seasons that looks cosmetic but channels water straight to the flue. We grind to substrate, apply a bonding agent, and re-pour with a modified mix that includes integral waterproofing - or we recommend a HeatShield crown seal if the structure underneath is sound.
• Gelco Flashing Kits (standard and custom): The standard kit’s step flashing works on newer construction with straight courses, but Haverhill’s post-and-beam capes and Victorian brick often need custom bending that the stock pieces can’t manage. We fabricate on-site from copper or coated steel, integrate with the existing Gelco cap, and seal with a high-temp polyurethane that stays flexible below zero.
• Gelco Smoke Chamber Parge Mix: This gets overlooked because it’s hidden, but we’ve pulled failed parge jobs in Bradford where the original contractor used standard mortar instead of the lightweight, insulating mix Gelco specifies. The result: heat transfer to surrounding framing, and in one case on Columbia Park, a Stage III creosote fire that cracked the flue. We remove the bad parge, reshape with proper refractory material, and document with camera footage before we close it up.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, 24/7. We book a Level 2 inspection with camera scan - Haven Standard Clause 4 requires the photo record, and we’ve done it that way since 2009.
2. 2
   On-site diagnosis. Corrine or one of our uniformed, background-checked techs arrives with the camera, moisture meter, and combustion analyzer. We identify the Gelco series, document the failure, and show you the footage on a tablet before we quote.
3. 3
   Written price and scope. You get a flat price, a written scope of work, and a written warranty - Haven Standard Clause 1, “Have it in writing.” No work starts until you approve.
4. 4
   Parts decision. We stock common Gelco hardware, DuraFlex liners, and HeatShield materials through our Haven buying network. If your repair needs a Gelco-specific part we don’t carry, we source it with a clear timeline - no mystery delays.
5. 5
   Repair and test. We complete the work, run a smoke test or pressure test depending on the repair, and clean the work area. The camera goes back down for after photos.
6. 6
   Documentation and follow-up. You receive a photo record, written warranty, and our 365-Day Done Right Promise. We file a copy in our archive - every one of our 38,000+ jobs since 2009 lives in that record.

Why Haverhill Homeowners Call Level Two Chimney Haverhill for Gelco Work

We’re not a brand-authorized dealer. We’re an independent Gelco service provider who happens to know these products because we’ve repaired thousands of them across the Merrimack Valley. The camera doesn’t guess. Neither do I - Corrine Halstead’s been doing this work for eighteen years, and her crew knows the difference between a Gelco Model L weld failure and a DuraFlex equivalent that needs different support hardware.

Every job carries the 365-Day Done Right Promise, Clause 4’s documented photo record, and a Free Second Opinion on any competitor’s written estimate. Our materials come through the Haven buying network - Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, Copperfield - which keeps prices honest and options open. Background-checked techs, license number on the page, text when we’re en route. That’s the Haven Standard.
