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.

AfterWhy Haverhill Homeowners Choose Gelco Chimney Cleaning
We provide independent Gelco in Haverhill chimney cleaning, inspection, and repair service throughout the Merrimack Valley. Our technicians work on Gelco stainless liner systems, single-flue and multi-flue caps, and crown accessory kits - not through any manufacturer authorization, but through years of hands-on diagnosis with Gelco components in the field. Every Gelco job we take in Haverhill starts with an NFPA 211 Level 2 camera inspection, a written price before any work begins, and a documented photo record when we’re done. Call (351) 444-9705 to book.
Gelco’s stainless steel flexible liner kits and cap systems are common in Lawrence Gelco service areas and Haverhill’s older housing stock - particularly in the Bradford neighborhood and downtown triple-deckers where wood stove inserts were added to original coal-era chimneys. The brand’s 6-inch and 8-inch round and oval liner systems were specified for many local installs in the 2000s and 2010s. We’ve cleaned and repaired enough of them to know where they hold up and where they don’t in our river-valley climate.
Why Trust Level Two Chimney Haverhill for Your Gelco Chimney Cleaning?
Corrine Halstead, who runs our crew, picked up her first flue brush at a continuing education program at Kingsborough Community College in Queens - a night course on building systems that turned into eighteen years of chimney work. She’s spent the last several years running jobs through the Merrimack Valley, including plenty of older brick-and-mortar colonials near Washington Square in Haverhill where the flues narrow and the creosote tells you exactly how long it’s been since anyone looked. The camera doesn’t guess. Neither do I. That applies to every Gelco system we touch.
Our Gelco expertise comes from tear-downs, not training manuals. We’ve found Gelco liner couplings pulled apart at the joint because the liner wasn’t properly secured during a prior install. We’ve pulled caps where the screen had rusted into a solid sheet, killing draft entirely. We’ve seen top plate sealant fail across three sides of a crown after three Haverhill winters. That field history means we can look at a Gelco component and tell you whether it’s worth saving - and we’ll put that assessment in writing, with photos, before we ask for a decision.
We’re independent. Not authorized by Gelco, not sponsored, not warranty-endorsed. That independence lets us recommend a HeatShield or DuraFlex alternative when a Gelco part is backordered or when the price premium isn’t justified by the performance gain. Clause 1 of the Haven Standard requires a written price, written scope, and written warranty before work starts. On every Gelco job, that’s exactly what you get.
Common Gelco Chimney Cleaning Problems We Fix in Haverhill
- Liner sized one step small for the appliance collar. This is a Gelco flexible liner kit issue we see repeatedly in Haverhill retrofits. The installer matched the liner to the existing flue diameter rather than the appliance output, so the top adapter plate never seated flush. Smoke and condensate leak into the smoke chamber, depositing creosote on the chamber walls where it hardens into Class III glaze. A Level 2 camera finds it. We quote the correct adapter or a full reline with proper sizing - no guesswork.
- Cap screen rust-through or band sag. Gelco single-flue and multi-flue caps use mesh screens that take the brunt of Haverhill’s freeze-thaw cycles. When the screen rusts through at the weld or the band sags, water pools on the crown and drops straight into the flue. In the Merrimack River valley, that moisture accelerates creosote-to-tar conversion and spalls the crown from below. We stock replacement Gelco caps and screens locally, and we’ll show you the rust pattern on camera before quoting.
- Top plate sealant failure at the crown. The Gelco cap meets the crown through a top plate that’s sealed with compound. In Haverhill, late-season nor’easters leave standing water in unprotected flues well into April. That water freezes, expands, and cracks the sealant across the plate. We’ve pulled caps where the caulk had failed on three sides - invisible from the ground, obvious under a camera. We remove the cap, re-seal with crown-compatible sealant rated for our temperature swings, and document the repair with photos.
- Liner couplings and appliance adapters pulling apart. Gelco liner systems rely on proper tensioning and support at the top and bottom. When a prior install skipped the support band or used the wrong termination, the coupling works loose. The gap undermines draft, lets creosote collect at the break, and can leak carbon monoxide into the smoke chamber or living space. Our Level 2 inspection catches the separation; our repair reseats the coupling with proper mechanical support, or we quote a full reline if the liner is too far gone.
- Oversized flues with Gelco liners installed without proper reduction. Haverhill’s mill-era chimneys - especially the triple-deckers in Bradford where two or three units share a single exterior stack - were built for coal or oil and later converted. A Gelco liner dropped into an oversized flue without a reduction sleeve creates turbulent draft, poor appliance efficiency, and rapid creosote buildup at the liner crown. We measure the flue and the appliance output, then specify the right Gelco oval or round system or recommend a HeatShield cerfractory seal if the liner is sound but the fit is wrong.

AfterGelco Parts & Our Repair-vs-Replace Approach
When a Gelco system is still structurally sound, we default to genuine Gelco replacement components. The dimensions, banding, and adapter geometry are proprietary. A mismatched aftermarket cap or adapter plate is a guaranteed callback, and we don’t do callbacks. We stock Gelco single-flue caps, multi-flue caps, and common 6-inch and 8-inch adapter plates in our Haverhill-area inventory for same-visit replacement when the diagnosis supports it.
When a Gelco liner is corroded through at the joints, when the flue is demonstrably undersized for the appliance, or when the prior install compromised the liner support system, we say so plainly. We’ll quote a full reline rather than patch a system that fails again within a season. DuraFlex and HeatShield are viable alternatives when Gelco parts are backordered or when the price premium isn’t justified. You’ll get that comparison in writing, with photos, before any work starts. Call (351) 444-9705 for an exact quote - estimates are free.
Our Gelco Service Process - Step by Step
- 1
Diagnosis: NFPA 211 Level 2 camera inspection. We run a camera down the full flue length, inspect the smoke chamber and firebox, and photograph the Gelco cap, crown, and top plate from the roof. In Haverhill, we’re specifically looking for freeze-thaw sealant failure, rust patterns on cap screens, and liner coupling gaps that prior sweeps may have missed. You get the footage and a written condition report.
- 2
Written scope and price. Before any work begins, we deliver a written price, written scope, and written warranty - Haven Standard Clause 1. No exceptions. If we find a Gelco liner that needs reline rather than repair, we explain why and quote DuraFlex or HeatShield alternatives if they make sense for your system.
- 3
Repair or install with genuine or specified parts. We use Gelco OEM components when the system warrants it, or specify the alternative in writing if we’re substituting. Background-checked, uniformed technicians; license number on the page; text when we’re on the way.
- 4
Post-work testing and documentation. We run a smoke test or draft test to confirm the repair, then deliver a documented photo record of the completed work - Haven Standard Clause 4, the practice we’ve maintained since 2009. Every Gelco job enters our archive.
- 5
365-Day Done Right Promise. If it’s not done right, we make it right. Stamped on every job.

FAQs - Gelco Chimney Cleaning Service in Haverhill
No. We are an independent service provider - not authorized, sponsored, or warranty-endorsed by Gelco. That independence lets us recommend genuine Gelco parts when they fit, or DuraFlex and HeatShield alternatives when they don’t, without manufacturer pressure. Call (351) 444-9705 to discuss your system.
Yes, when the existing Gelco system is still sound and the proprietary dimensions or banding make OEM the right choice. We stock common Gelco caps and adapter plates locally. When a Gelco part is backordered or an alternative offers equivalent performance at a better value, we explain that in writing and let you decide.
A standard Gelco sweep and Level 2 inspection takes 60 to 90 minutes. Cap replacement or adapter resealing adds 30 to 60 minutes. A full Gelco reline in a Haverhill triple-decker with shared flues can take a half day. We give you a time estimate in writing with the price - no open-ended bookings.
We service and install Gelco stainless steel flexible liner kits, single-flue and multi-flue chimney caps, masonry crown and flashing accessory kits, and round and oval liner systems in 6-inch and 8-inch sizes.

Many older Gelco liner components remain available through our supply network, though some sizes and adapter configurations have been discontinued as the product line evolved. We verify parts availability during the initial inspection and quote a HeatShield or DuraFlex alternative if the exact Gelco match is no longer manufactured. You’ll know before we start, not after.
It depends on your fuel and your neighborhood. Gelco Chimney Cleaning in Methuen Town, MA uses similar mesh screens that work well for wood-burning appliances where spark arresting matters, but in Haverhill’s Bradford area - where triple-deckers share chimney stacks and one unit’s wood stove can contaminate another’s oil flue - the screen must be inspected annually for creosote bridging. For oil or gas-only flues, we sometimes recommend a Gelco cap with a rain guard and no mesh to reduce maintenance burden. We assess your actual usage and quote accordingly.
The camera tells you. We look for corrosion at the joints, separation at couplings, and pitting that penetrates the stainless wall. In Haverhill’s Merrimack River valley climate, moisture drawn up from the river accelerates deterioration in liners that were already marginal. If the Gelco liner is intact but the flue is oversized for the appliance, we may recommend a reduction sleeve or a HeatShield seal rather than full replacement. The Level 2 footage shows you exactly what we see.
Not always, but it should be inspected. The top plate sealant is a common failure point in Haverhill’s freeze-thaw environment, and we can’t assess it without lifting the cap. We remove Gelco caps as standard practice during a Level 2 inspection - it’s the only way to photograph the crown condition and verify the liner termination. If the sealant is sound, we reseat the cap with fresh compound. If it’s cracked, we reseal with crown-compatible material rated for our temperature swings.
Yes, if that’s the right solution for your system. We stock several cap lines and will match the dimensions, mesh spec, and banding to your flue. We specify the alternative in writing with photos of the existing cap and the proposed replacement, so you can compare before deciding. Haven Standard Clause 1: have it in writing.
