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.
Gelco Chimney Cleaning & Sweep in Lawrence: What to Know First
Independent Gelco chimney cleaning and sweep in Lawrence typically runs $189 to $329 for a standard annual cleaning with a Level 1 inspection, and most jobs are completed in 60 to 90 minutes. We are not affiliated with Gelco, but we work on their chimney systems regularly across Lawrence, from the older colonials near Central Avenue to the mid-century ranches south of Rockaway Turnpike. If you own a home with a Gelco chimney system and need it cleaned, inspected, or evaluated, call (516) 604-2573 and you will get a live person, not a phone tree.

This page is for Lawrence homeowners who want a chimney sweep that knows Gelco systems specifically. Not a franchise that sends a different face every year. Wendell Pike and his crew have been inside Gelco flues in Lawrence long enough to know which ones hold up and which ones quietly fail. You will get the camera footage and a plain-English verdict. Every time, no exceptions.
How Gelco Products Fail - and How We Fix Them
Gelco chimney systems are common in Lawrence, and they have their own failure patterns. Not every problem shows up as a smoky fireplace. Some of them are invisible until a camera goes in. Here is what we actually see on Gelco jobs in Lawrence:
- Gelco stainless steel liners with creosote glazing at the corbel. On masonry chimneys in Lawrence’s older homes, we find Gelco liners that run fine through the straight sections but collect hardened creosote where the flue shifts slightly at the smoke shelf. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early, before it requires rotary treatment.
- Gelco chase covers with rust-through at the seams. Lawrence sits close enough to the Atlantic that salt air finds weak points in chase covers made of lighter-gauge steel. We have pulled covers with holes you could put a pencil through. The fix is a proper stainless replacement, not caulk.
- Gelco clay tile liners with spalling in the upper third. In Lawrence homes built before 1980, original Gelco clay tile liners often show spalling in the top twelve feet, where moisture from Long Island winters freezes and thaws. A liner that has spalled more than once has been patched one too many times. The camera will show you exactly where it is.
- Gelco multi-flue caps with plugged spark arrestors. We clean more Gelco multi-flue caps in Lawrence than just about any other single component. The mesh collects creosote and debris until the draft chokes. Your flue doesn’t care how the fire looks. It cares how it breathes.
- Gelco fireplace dampers that no longer seat. In Lawrence houses where fireplaces burn hard through the winter, Gelco dampers can warp enough that they no longer close fully. That sends warm air up the flue all season and lets cold air drop in. Some dampers can be adjusted. Some need replacement. We will tell you which one applies and whether the job can wait.
Our Gelco Chimney Cleaning & Sweep Process
When a Lawrence homeowner calls us about a Gelco chimney, here is how the job goes, start to finish:
- 1
Call and booking. You call (516) 604-2573, a live person answers, and you get a real arrival window. No call center. No eight-hour windows.
- 2
Arrival and setup. Wendell or one of his crew shows up in uniform, background-checked, and lays down drop cloths before anything else. Your floors stay clean.
- 3
Camera inspection before the brush. We run a camera up the flue before we touch a brush. You see the condition of your Gelco liner, cap, and damper on screen. If it’s clean, I’ll tell you it’s clean.
- 4
Cleaning with brushes sized to your flue. We use brushes matched to the actual dimensions of your Gelco flue, not whatever is on the truck. Soot and creosote come out, not into your living room.
- 5
Post-clean camera check. After the sweep, the camera goes back in. You see the result, and we point out anything that needs attention now or can wait until next season.
- 6
Straight verdict and 90-Day Done Right Promise. We tell you plainly what we found and what it costs to fix it, if anything. Every job is backed by our 90-Day Done Right Promise in writing. If it is not right, one call brings us back.

FAQs
Once a year, burn or no burn. Chimneys break in the off-season too. In Lawrence, we recommend an annual sweep and Level 1 inspection even if you only burn occasionally, because moisture and salt air work on flue components all twelve months. Call (516) 604-2573 to schedule. We will give you a real arrival window.
No. Routine cleaning and inspection by a qualified independent chimney company does not void Gelco warranties. What voids warranties is neglect, improper installation, or repairs done with incorrect parts. We follow manufacturer specs when cleaning, and we document the job with camera footage, which is exactly what you want if you ever need a warranty claim approved.
Usually, yes. We book by appointment, not on-demand the way some national outfits promise, but we typically schedule Lawrence chimney sweeps within a week, and we show up when we say we will. Call (516) 604-2573 and we will get you on the calendar with a live person, not a call center.
We use OEM Gelco parts when they are available and the job calls for them. For some older Gelco components, OEM parts are discontinued, and a quality aftermarket equivalent is the only path. We will show you the difference, explain what fits and what does not, and give you a straight recommendation. Nothing gets installed without your say-so. We have trusted relationships with major chimney brands including DuraFlex and HeatShield, so you are getting parts from names the industry respects, not whatever is on a warehouse clearance shelf.
Creosote builds up, and creosote is fuel. In Lawrence homes with Gelco liners, we have seen flues where first-degree creosote turned to third-degree glaze in just two or three seasons of regular burning. A chimney fire is fast and hot, and the first sign is often a sound like a freight train in the wall. You do not want that. A $189 to $249 annual sweep is the cheapest insurance on your house. Call (516) 604-2573 and we will take care of it. Estimates are free.
