Why Trust Manchester Chimney Cleaning for Your Gelco Chimney Cleaning?

Our crew has swept, inspected, and repaired Gelco chimney systems across Manchester for years, so we know how the liners, dampers, and crowns age in New England freeze-thaw cycles. We know what a crushed corrugation looks like at the offset of a Gelco flexible liner, and we know the sound a loose Gelco single-flue cap makes when wind works its leg screws free.

That familiarity is why we work with quality parts that fit the equipment rather than improvising a fit. When we replace a Gelco cap or a section of liner, we match flue size and BTU rating, seat the part level, and check the draft before we leave. We don’t claim factory training or certification, and we won’t call ourselves a Gelco dealer. What we offer is a working knowledge of the product in the conditions Manchester actually creates.

Tim Sandoval leads our work and grew up in the Youngsville neighborhood, so the triple-deckers off Elm Street with their shared chimney stacks aren’t abstractions to him. He trained in building and construction trades at Manchester Community College before spending years on chimney work across southern New Hampshire, learning masonry liners, wood stove inserts, and smoke chamber repairs job by job. He worked in the trade well before starting Manchester Chimney Cleaning in 2012. Neighbors tend to call him when a Level 2 inspection turns up something the last guy missed.

Common Gelco Chimney Cleaning Problems We Fix in Manchester

Gelco failures in this city tend to repeat themselves. Here’s what we run into, and why:

• Flexible liner corrugations crushed or joints separated at offsets. A Gelco stainless flexible liner takes a bend at every offset in the flue, and that’s where the metal works hardest. Years of sweeping with an oversized brush, plus the flexing that comes with heating and cooling, can flatten corrugations or pull a joint apart. Once that happens the liner no longer contains the flue gases the way it should, and you get smoke spillage or a draft that won’t hold. We inspect the offsets specifically, not just the straight runs.
• Top-mount multi-flue cap screens glazed shut with creosote. This is the most common call we get on Gelco top-mount multi-flue caps. The stainless mesh screen does its job trapping sparks and debris, but wood smoke carries creosote, and creosote collects on that mesh until it glazes solid. A glazed screen chokes the draft on every flue under the cap. Your wood fireplace gets smokey and hard to light, and the problem looks like a firebox issue when it’s really a cap issue.
• Single-flue caps shifting off-center at the leg screws. A Gelco single-flue cap with a mesh screen sits on legs that anchor at the crown. Wind, freeze-thaw movement, and simple vibration loosen those leg screws over time. The cap shifts, rainwater finds the gap, and it runs down the flue to rust the damper. By the time a homeowner notices the damper sticking, the cap has been off-center for a while. We check cap seating on every sweep for this reason.
• Clay flue tiles spalling and cracking at the mortar joints. Gelco clay tile liners in Manchester age the same way every clay liner does here: freeze-thaw cycles get into the mortar joints, water expands, and the tile face flakes and cracks. It happens faster wherever a Gelco cap has been removed or damaged, because the flue is then open to spring rain. Spalling tile isn’t cosmetic. It narrows the flue and can allow heat to reach the chimney’s structure.
• Caps missing or damaged, letting water into the whole system. A chimney without a working cap is a chimney taking rain. In Manchester’s climate the consequence shows up as spalled brick, cracked crown mortar, and rusted damper hardware. If your Gelco cap is missing or bent, we treat that as the first thing to fix, because every other repair lasts longer once the water is off the chimney.

One Manchester customer with a Gelco top-mount multi-flue cap called because their wood fireplace had gone smokey and hard to light. Our tech found the stainless mesh screen glazed solid with creosote and the cap legs bent, tilting it off the crown. We performed a Level 1 inspection, swept the flue, removed the glazed screen, and installed a new Gelco-style multi-flue cap seated level with fresh stainless mesh. The draft came back immediately. That’s the pattern we see over and over: the cap looks fine from the ground, and the screen is the whole problem.

Gelco Parts & Our Repair-vs-Replace Approach

We fit OEM Gelco caps, liners, and dampers when the existing system is intact and the part is available. When an exact Gelco match is discontinued or back-ordered, we use quality aftermarket stainless components instead, always matching flue size and BTU rating so the part does the job the original did. What we won’t do is force a part that doesn’t fit and call it close enough. We don’t stock or sell genuine Gelco parts as a dealer; we’re a service shop that works with the equipment you already have.

Repair versus replace comes down to the condition of what’s underneath. If a Gelco liner is crushed or a joint has separated, we replace that section rather than patch it, because a patch on flexible stainless doesn’t restore the containment. If the clay tiles and crown are sound, we repair and reline instead of pushing a full rebuild. Nothing gets recommended without camera evidence you can see for yourself, and we’ll tell you plainly when work can safely wait.

Our Gelco Service Process – Step by Step

1. 1
   Diagnosis. We start with a camera inspection of the flue and a close look at the cap from the roof. On a Gelco flexible liner we check the offsets for crushed corrugations and separated joints. On a multi-flue cap we check the mesh screen for creosote glaze and the legs for level seating. You see what we see, and we tell you which Gelco part is failing.
2. 2
   Repair or install. We sweep the flue and remove creosote first, because no cap or liner works well over a dirty flue. Then we fit the part: a replacement cap seated level with fresh stainless mesh, a new liner section matched to flue size and BTU rating, or a damper repair once the water intrusion is stopped. Creosote removal happens before anything gets sealed back up.
3. 3
   Test. We check draft with the appliance running and confirm the cap sits level on the crown. A smokey fireplace that tested poorly before should draw cleanly now. If it doesn’t, we haven’t finished.
4. 4
   Warranty and documentation. We document the work and the parts so your records stay clean for any Gelco warranty question. If a part we installed ever needs attention, you’ll know who to call.

Gelco Products We Service & Install in Manchester

We work on the Gelco products Manchester homes actually have:

• Gelco Stainless Steel Flexible Liner Kits – installation, section replacement, and inspection at the offsets where flexible liners take the most stress.
• Gelco Top-Mount Multi-Flue Caps – installation, screen replacement, and re-seating. These are the caps most likely to glaze shut on wood flues.
• Gelco Single-Flue Caps with Mesh Screens – replacement and re-seating when leg screws loosen and the cap drifts off-center.
• Gelco Clay Flue Tile Liners – inspection, spall assessment, and relining where the tiles are sound enough to keep.

In the dense blocks off Elm Street, many triple-deckers share a single stack with multiple flues, and it’s common to find one flue venting a gas furnace and another a wood stove. Cleaning those requires isolating each flue so nothing cross-contaminates. That’s especially true under a multi-flue cap, where one glazed screen can affect every flue beneath it. From annual sweep to full liner restoration, we handle all of it in Manchester.

We Also Service These Brands

Gelco isn’t the only equipment we know. We work with DuraFlex flexible liner systems for older or complex flue configurations where a rigid liner won’t fit, and we’re equipped with HeatShield for chimney liner restoration, which is often a cost-effective alternative to full relining. Famco dryer vent products round out the work we do on your home’s second fire-risk flue. One crew, one call, whichever brand is on your chimney.
