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 Cleaning & Sweep in Yonkers: What to Know First
Gelco chimney cleaning and sweep in Yonkers typically runs $189 to $340 for a standard sweep and Level 1 inspection, with most jobs completed in under two hours. If we’re running a camera down the flue for a Level 2 inspection, which we do on every visit, the price lands between $249 and $449 depending on flue height and access. We’re an independent Gelco service provider, which means we work on Gelco liners and components without being tied to Gelco’s warranty department or pricing structure. If you own a Gelco chimney system in Yonkers and want an honest assessment of what’s inside it before anyone touches a brush, call (551) 212-3526.
How Gelco Products Fail - and How We Fix Them
Gelco makes solid chimney components, but every brand has weak points. Here’s what we actually find when we run a camera down a Gelco flue in Yonkers homes.
- Gelco stainless steel liners and creosote glaze. The Gelco liner itself holds up well, but the smooth interior wall gives creosote a surface to glaze onto, especially in Yonkers colonials with older masonry chimneys and poor draft. Once creosote hits Class II or Class III, meaning it’s baked-on and tarry rather than brushable soot, a standard sweep won’t touch it. We use mechanical rotary tools to break the glaze without scoring the liner.
- Gelco termination caps and Yonkers tree litter. Gelco’s multi-flue caps and custom caps do their job, but the mesh around them catches maple and oak debris from mature trees in neighborhoods like Park Hill and along the Saw Mill River corridor. That mesh clogs, draft drops, smoke backs up into the house. We remove the cap, clean the mesh, and document what came out. If the mesh is torn from squirrel activity, we recommend replacing the cap with a comparable unit rather than patching.
- Gelco chase covers and hidden water entry. The chase cover is the galvanized or stainless lid at the top of a prefab chimney chase. Gelco chase covers are durable, but the caulk joint where the cover meets the chase fails after eight to ten years of Hudson Valley freeze-thaw cycles. Water gets in behind the siding, rusting the chase top and sometimes the flue pipe collar. A standard sweep won’t catch this. Our camera inspection will, because we look at the entire system, not just the flue interior.
- Gelco flex liners and connector pipe separation. On Gelco flex liner installations, the connection between the liner and the appliance connector pipe, the short rigid section that transitions into the liner, is a common separation point. If the original installer used sheet metal screws that weren’t stainless, they rust and fail. You’ll smell smoke or get a CO reading near the connection. We re-secure it with the proper stainless hardware and verify the joint with the camera.
- Gelco masonry repair products and spalling brickwork. Gelco offers masonry repair and waterproofing products. What we see in Yonkers is that the chimney crown, the concrete cap on top of the masonry, starts spalling, meaning the surface flakes and crumbles, long before the liner fails. If the crown is compromised, water works its way into the flue, mixes with the creosote, and creates an acidic slurry that eats mortar joints. We repair or replace the crown and then sweep, not the other way around. Sweeping a flue with a failed crown is wasted motion.
Our Gelco Chimney Cleaning & Sweep Process
Every Gelco job we run in Yonkers follows the same sequence, and you’ll have the written record of it when we leave.
- 1
Written price before the tech arrives. When you call, we quote a flat price for the sweep and inspection over the phone. That price is written down and confirmed before anyone rings your doorbell. Clause 1 of the Haven Standard, the standard we’ve worked to since 2009, requires the written price before work starts. No exceptions.
- 2
Named tech and on-the-way text. You’ll know which background-checked, uniformed technician is coming. Our techs carry their credentials and the company license number on the page with the name. You get a text when they’re en route.
- 3
Level 2 camera inspection of the Gelco system. Before we sweep, we run the camera from the firebox to the termination cap. The camera doesn’t lie, and neither does the quote. We’re looking at the Gelco liner condition, the creosote class, the cap, the chase cover if you have one, and the connector pipe. This is Clause 4 of the Haven Standard, the photo record on every job, and we’ve done it on all 38,000-plus chimneys we’ve inspected since 2009.
- 4
The sweep itself. We stage drop cloths and run our rotary cleaning system appropriate to what the camera showed. Class I soot gets brushed. Class II or III creosote gets mechanical removal. We don’t upsell you on a process you don’t need. If the liner is clean, we say so.
- 5
Post-sweep camera verification and documentation. We run the camera again after the sweep and show you the before and after. You get the photos, a written scope of what was done, and a written warranty if any repair work was performed. The 365-Day Done Right Promise applies: if it’s not done right, we make it right.
- 6
Cleanup and walkthrough. We leave the hearth cleaner than we found it. We’ll walk you through anything we found, plain-spoken, with the numbers. If something can wait a year, we say so. If it can’t, you’ll see why on the camera feed.
BeforeAfterWhat Gelco Chimney Cleaning & Sweep Costs in Yonkers
Here are the ranges we quote most often for Gelco systems in Yonkers homes:
- Standard sweep with Level 1 inspection: $189 to $289. Most single-flue Gelco systems with a clean or lightly sooted flue land here.
- Sweep with Level 2 camera inspection: $249 to $449. Includes the full video record of the flue, which you keep.
- Heavy creosote removal, Class II or III: $340 to $540. Mechanical rotary removal takes longer and requires the heavier equipment. You’ll see the glaze on the camera before we start.
- Gelco chase cover or cap replacement: $95 to $380 for parts depending on the model and material, plus $145 to $220 for the installation. We source through the Haven buying network with materials from Gelco, DuraFlex, HeatShield, and other manufacturers to keep the price honest, not padded for the Yonkers zip code.
What moves the price is flue height, creosote class, and whether the cap or chase cover needs work. The written quote you get covers all of it, and it never changes mid-job. Call (551) 212-3526 for an exact number before you book. Estimates are free.
Why Yonkers Homeowners Call Level Two Chimney Yonkers for Gelco Work
Most of our Gelco customers in Yonkers found us through a neighbor or a three-star review that said we were honest about what didn’t need fixing. That’s Corrine Halstead’s default position: name the problem, give the number, move on. We’ve been doing camera-documented chimney work in Westchester County for the better part of two decades, and we’ve swept and inspected Gelco systems in older colonials near the Hudson River Museum corridor, in narrow row houses, and in homes where the chimney hadn’t seen a brush in fifteen years. We also service DuraFlex and HeatShield products, so when a Gelco component isn’t the right call, we’re not stuck selling you something you don’t need. The written price, the written scope, and the written warranty happen before the work starts. The 365-Day Done Right Promise stays after we leave. If it’s not done right, we make it right.
FAQs
No. A professional sweep by an independent Gelco service provider does not void a Gelco product warranty. Sweeping is required maintenance for any chimney system, and Gelco’s warranty documents expect it. We’re not authorized by Gelco, and we’ll never imply we are, but we’ll also never perform a sweep that compromises the liner. What does void a Gelco warranty is damage from neglect, like letting Class III creosote sit in the flue or running the fireplace with a failed chase cover. We document the condition before and after with the camera, so you have a record that says the system was properly maintained. Call (551) 212-3526 to schedule and get a written price before we arrive.
Every 40 to 50 fires, or once a year, whichever comes first. If you burn wood in a Gelco fireplace weekly through a Yonkers winter, you’ll probably hit that threshold each season. If you burn mostly seasoned hardwood and you’re attentive, you might get two seasons. Creosote builds faster with green wood, slow smoldering fires, or a flue that’s oversized for the fireplace. The camera tells you exactly where you stand. We’ll show you the Class I, II, or III creosote on the screen and tell you plainly if it’s time or if you can go another year.
Yes, in most cases. We source through the Haven buying network, which carries Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. If a Gelco termination cap is discontinued or backordered, a DuraFlex or Olympia cap with the same dimensions and material spec is usually a drop-in replacement. We’ll always show you the option and the price difference before ordering. We’re not tied to any single manufacturer, so we’ll recommend the part that makes the most sense for your Yonkers home, not the one with the highest margin.
Creosote accumulates in layers. Class I is flaky soot that brushes off easily. Class II is granular, baked-on, and needs mechanical removal. Class III is a hard, tarry glaze, and it’s a chimney fire waiting for a spark. A chimney fire in a Gelco liner doesn’t usually destroy the liner itself, since stainless steel handles high heat better than clay tile. But a chimney fire can crack the surrounding masonry, melt the cap mesh, and warp the chase cover, and the heat transfer to nearby framing is the real danger. If you’ve skipped a sweep, more than one season, or you’ve bought a house that hasn’t been swept in years, call (551) 212-3526. We’ll get the camera in the flue before we touch a brush.
Most Gelco sweeps in Yonkers are booked within three to seven days, though we hold same-week slots during peak burning season for homeowners who’ve spotted a problem. Live phone support runs 24 hours a day, 7 days a week, so if you call at 9 p.m. you’ll talk to a person, not a voicemail. We’ll give you the written price on that call and schedule the named tech. No countdowns, no pressure, just a time on the calendar and a number that won’t change.
