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 Commack: What to Know First
We clean and sweep Gelco chimneys in Commack, and most jobs are done in under two hours. A standard Gelco chimney cleaning and Level 1 inspection runs $189 to $289, depending on flue condition and whether you burn wood or gas. You’ll know the exact number before a single tool comes off the truck, and if the chimney doesn’t need cleaning yet, Wendell will tell you that too.
This page is for Gelco owners in Commack who want a straight answer on what their chimney needs. Call (631) 502-3612 and you’ll get a live person, not a voicemail box.
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 see in Commack homes, and what we do about it.
- Gelco stainless steel liners and creosote glaze. Gelco’s 316L liners hold up well, but we’ve pulled third-degree creosote glaze off them in Commack fireplaces that burned a lot of pine or unseasoned oak. First-degree creosote is a brush job. Third-degree is a glaze. On Gelco liners, that glaze hides behind the corrugation ridges where a flat brush misses it. We use rotary whip heads sized to the liner diameter so the ridges get cleaned, not just the high points.
- Gelco caps with mesh that clogs fast. Gelco’s standard mesh caps do their job, but in Commack the mesh collects airborne seed fluff and leaf debris faster than most people expect. A clogged cap starves the flue of draft, so the fireplace smokes back into the room. The fix is usually a cap-off cleaning and, if it’s a recurring problem, stepping up to a larger mesh opening that still keeps animals out but breathes easier.
- Gelco chase covers and water entry at the seams. Gelco chase tops are factory-welded, but on older Commack installs we see seam rust where the installer caulked instead of using the OEM gasket. Water gets in, runs down the liner, and leaves rust streaks on the firebox floor. We clean the system, then reseal with a high-temp silicone rated for flue temperatures, not whatever was on sale at the hardware store.
- Improper flashing on Gelco terminations. A lot of Gelco chimneys in Commack were installed by roofing crews during a re-roof, not by chimney people. The flashing leaks at the roofline and the homeowner thinks the chimney is failing. It’s not, most of the time. The termination needs to be pulled, the flashing corrected, and the collar re-bedded. That’s a two-hour fix we do during a cleaning visit when we spot it.
- Mixed-brand installations causing draft issues. We see Gelco liners paired with off-brand connectors because a previous contractor used whatever was on the truck. Mismatched male-to-female connections create turbulence and condensation pockets. On a cleaning call we map what’s actually in the flue and tell you plainly whether the components are safe to keep using or whether one section needs replacing to make the system breathe right.

Call and get a real answer. You call (631) 502-3612, describe your fireplace and when it was last swept. We give you a firm price range on the phone.

Arrive with a window, not a surprise. Background-checked, uniformed crew shows up in the window we promised. We call if we’re running late.
- 3
Protect the room first. Drop cloths, a HEPA vacuum running, and the fireplace sealed off before we touch the flue. No soot on your rug, ever.
- 4
Inspect, then sweep. We camera the flue first to see what we’re dealing with. The camera footage and a plain-English verdict, every time, no exceptions. Then rotary cleaning matched to your Gelco liner size.
- 5
Fix what needs fixing. If we find a problem, we price OEM Gelco parts where it matters and quality aftermarket where it doesn’t. You approve the number before we touch it.
- 6
Test and guarantee. We run the fireplace, verify draft, and the 90-Day Done Right Promise goes in writing on your invoice. If it’s not right, one call brings Wendell back.
What Gelco Chimney Cleaning & Sweep Costs in Commack
Here’s what Gelco owners in Commack actually pay, based on the condition of the flue.
- Gas fireplace Gelco chimney sweep: $149-$219
- Wood-burning Gelco chimney sweep with Level 1 inspection: $189-$289
- Level 2 camera inspection after a storm or real estate sale: $249-$349
- Creosote glaze removal on a Gelco liner: $350-$550, depending on severity

What moves the price is how much glaze has built up, whether the cap needs removal, and how long it’s been since the last cleaning. Skip the guesswork and call for a free estimate, $40 off any repair over $200 applies, and seniors and veterans always save 10%.
Why Commack Homeowners Call Top Hat Chimney for Gelco Work
Wendell Pike started Top Hat Chimney in 1999. He’s been running crews through Suffolk County ever since, including plenty of jobs in the Burr Farms neighborhood of Commack. Ask anyone on your street. He learned the trade at Southwestern College in Chula Vista, picked up his first brush before he was twenty-five, and still answers the phone himself half the time.
We’re an independent Gelco service provider. We’re not owned by the brand, and we’re not a franchise that rotated in last spring. When we work on a Gelco chimney, we also know how it fits with the other major brands because we install and service DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. That means we can tell you honestly whether a Gelco part is the right fix or whether a HeatShield resurfacing makes more sense for your flue’s age. Nobody at a call center can give you that answer.
If it does not need doing, we will be the first ones to tell you.
FAQs
No. A professional cleaning and inspection actually helps you stay within Gelco’s warranty terms, which require the chimney to be maintained. We document every job with camera footage, so if you ever need to make a warranty claim, you have proof the chimney was serviced properly. We’re an independent Gelco service provider, so we follow the manufacturer’s specs without being shy about telling you when a different part would serve you better.
Once a year, burn or no burn. Chimneys break in the off-season too. Commack’s humidity accelerates rust on chase covers and dampers, and a chimney that sits unused all winter still collects condensation, nesting material, and debris. We recommend an annual sweep with a Level 1 inspection whether you use the fireplace twice a week or twice a season.
Most common Gelco caps, connectors, and terminations are available to us within a few business days through our regular supply chain. We stock the common sizes on the truck because we service enough Gelco chimneys in Commack to know what fails most. If a part is backordered, we’ll tell you the honest timeline before you commit to anything.
We won’t recommend a liner replacement unless the camera footage shows it. A dirty Gelco liner can look failed when it’s really just glazed over. That’s why we camera first and sweep second. If the liner is sound after cleaning, we’ll say so and save you the money. If the steel is cracked, pitted, or separated at a seam, we’ll show you the video and explain your options plainly. Your flue doesn’t care how the fire looks. It cares how it breathes.
Most cleaning jobs are scheduled within a week, and during the off-season we can often get there sooner. If you’re selling a house or just had a chimney fire scare, tell us on the phone and we’ll work you in. Call (631) 502-3612 for the next available window, and there’s no trip charge inside the county.
