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 Westchester County: What to Know First
Gelco chimney cleaning and sweeping in Westchester County runs $189 to $329 for a standard Level 1 sweep and inspection on a single-flue Gelco system. Most Gelco jobs are done in under two hours, and we book within a week most months except October through December, when every fireplace in the county lights up at once. You’ll get a flat quote before we touch anything, and if the camera shows the flue is clean enough to skip this year, we’ll tell you that and head out without charging for a sweep.
This page is for homeowners in Westchester County who have a Gelco chimney liner, cap, or chase cover and want someone who actually knows how those components age in this climate. If that’s you, call (914) 537-6479 and ask for Wendell or whoever picks up. We answer around the clock, and we don’t send you to a call center in another state.
Key takeaways:
- Independent Gelco service, not factory-authorized, and we’ll never pretend otherwise
- Every sweep includes a camera inspection and a plain-English verdict on what the liner actually needs
- Flat pricing before the first tool comes off the truck
- 90-Day Done Right Promise in writing on every job
- We service DuraFlex and HeatShield systems too, so you’re not stuck with a one-brand shop
How Gelco Products Fail - and How We Fix Them
Gelco makes solid chimney components, but everything wears, and some things wear faster in Westchester County’s freeze-thaw swings and long burn seasons. Here’s what we actually find on Gelco jobs around here.
- Gelco stainless liners with concentrated creosote at the first elbow above the firebox. The Gelco 316L liners handle heat well, but any liner with an elbow is a creosote catcher. In older Westchester County chimneys with offset flues, that first elbow is where soot builds into second-degree creosote fast. It’s not a Gelco defect; it’s geometry. We brush it hard and inspect that bend with the camera twice before we call it clean.
- Gelco chase covers rusting at the folded seams. This shows up on Gelco factory-built chimney chases more than the liners. The folded seams on Gelco chase covers hold water, and after enough Westchester County winters, that water turns to rust. We see it on homes from Armonk to Yorktown. The fix is usually a replacement cover with proper pitch, and we’ll show you the rust on camera before we recommend spending a dime.
- Gelco caps with bird and debris blockage. Gelco caps without mesh screens or with screens that have pulled loose let starlings, squirrels, and maple seeds into the flue. In Westchester County, we see a lot of winged and four-legged tenants in unscreened Gelco caps. The sweep clears the blockage, but if the mesh is torn, the fix is a screen repair or cap replacement, not just another sweep next year.
- Gelco clay tile liners with spalling in older chimneys. If your Gelco system includes original clay tiles, especially in pre-1970s homes around Ossining and Peekskill, water intrusion freezes and pops the tile faces. Spalled clay catches creosote and restricts draft. We can sweep what’s there, but if the camera shows structural spalling, a Gelco stainless liner installed under the existing system is often the honest long-term answer.
- Gelco zero-clearance fireplaces with clogged air-cooled chimneys. Gelco zero-clearance units use air-cooled chimney sections, and those air channels fill with dust, soot, and the occasional wasp nest. A homeowner runs the fire, the chimney can’t cool properly, and the unit overheats. The sweep includes clearing those air channels and checking the cooling path, something most generalist chimney companies skip entirely.
Our Gelco Chimney Cleaning & Sweep Process
Here’s how a Gelco chimney cleaning and sweep goes when you call Top Hat Chimney.
- 1
You call, a person answers. Tell us about your Gelco system, your last sweep, and anything odd you’ve noticed. We’ll quote a flat sweep price on the phone.
- 2
We show up in a window that holds. Wendell or one of his background-checked, uniformed crew arrives, and if traffic on the Taconic messes with the window, you’ll get a call before you wonder where we are.
- 3
We lay down drop cloths and run the camera first. Before any brush touches the flue, we send the camera up to see exactly what’s in there. First-degree creosote is a brush job. Third-degree glaze is a different conversation.
- 4
The sweep happens with brushes sized to your Gelco flue. We don’t drag a too-big brush through a 6-inch Gelco liner and call it done. The brush fits, the soot comes out, and the vacuum catches it.
- 5
Post-sweep camera check and honest verdict. We show you the before and after. If the liner is sound and the cap is intact, we say so. If something needs watching, we tell you what and when. If it doesn’t need doing, we’ll tell you that too.
- 6
We write it up. The invoice matches the phone quote. The 90-Day Done Right Promise is on the paper. You sign, we leave, and the fireplace is ready.
What Gelco Chimney Cleaning & Sweep Costs in Westchester County
Here’s what Gelco chimney cleaning and sweep work costs in Westchester County. These are the numbers we actually quote, not a teaser price that doubles at the door.
- Standard Gelco sweep with Level 1 inspection: $189 to $279, depending on flue count and roof access
- Sweep with Level 2 camera inspection: $289 to $379; Level 2 is what we recommend if you just bought the house or haven’t swept in three-plus years
- Heavy creosote removal (second or third degree): $329 to $475, slower work with specialty scrapers and more vacuum time
- Gelco cap or chase cover replacement: $250 to $700 installed, depending on size and material
- Gelco stainless liner inspection report needed for insurance: $99 to $149 when combined with a sweep
What moves the price: roof pitch and height, how many flues you have, whether the cap needs to come off, and whether the creosote is glaze rather than soot. We always give the number before we start. Call (914) 537-6479 for an exact quote. Estimates are free, and if you’re inside the county, so is the trip.
Why Westchester County Homeowners Call Top Hat Chimney for Gelco Work
Westchester County has no shortage of chimney companies, and we’re not the biggest. That’s deliberate. Wendell Pike started Top Hat Chimney in 1999, and we’ve been showing up at the same doors ever since. When you call, a live person answers, and it may well be Wendell himself on the line at midnight. The price you hear on the phone is the price on the invoice. Every job gets the 90-Day Done Right Promise in writing: if it’s not right, one call brings us back, no charge.
We work on Gelco systems, but we also install and service DuraFlex and HeatShield components, so when your Gelco cap needs a replacement that Gelco discontinued three years ago, we can reach for a DuraFlex cap that fits without pretending the brand sticker matters more than the function. Ask anyone on your street. Most of them already have our number.
FAQs
Once a year, burn or no burn. Even if you never light a fire, Westchester County winters push moisture into the flue, and that plus leftover soot and a few maple seeds make a mess that gets worse each season. Chimneys break in the off-season too. Call (914) 537-6479 and we’ll get you on the calendar.
Gelco’s liner warranty, like most stainless liner warranties, assumes normal maintenance, and that includes annual sweeping and inspection. A failed liner with three seasons of unbrushed creosote is a hard claim to make. We document every sweep with camera footage, so if you ever need to prove maintenance, you’ll have the receipts.
Almost never. A rusted Gelco chase cover is a cover problem, not a chimney problem. We replace the cover, seal it properly, and the chimney keeps doing its job. The camera footage and a plain-English verdict come with every job, no exceptions.
Most weeks, within four to seven days. In September and October, when the whole county suddenly remembers winter, it may be two weeks. If you smell smoke backing up or see soot falling into the firebox, call (914) 537-6479 and we’ll move you up. A real person answers every time.
Bring us any written estimate from another company and we’ll give you a free second opinion. If the work is the same, we’ll quote honestly against it. If the other estimate includes work that doesn’t need doing, we’ll tell you that too. If it doesn’t need doing, we’ll tell you that too.
