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 Liner & Rebuild in Deer Park: What to Know First
We repair and rebuild Gelco chimney liners in Deer Park and across Suffolk County, and most liner jobs take one full day from setup to final inspection. A stainless liner replacement typically runs $1,800 to $3,400 in this area depending on flue height and access, and we give you the exact number before any work starts. If a Gelco liner is salvageable, we’ll tell you that instead of selling you a new one.
This page is for Deer Park homeowners with a Gelco flue system who’ve been told they need a liner or a rebuild, or who’ve seen signs of trouble and want straight answers. If you’ve got soot streaks above the fireplace, a rust smell, or crumbling mortar inside the flue, call (631) 214-2108 and Wendell or one of the crew will walk you through what you’re seeing.
How Gelco Products Fail - and How We Fix Them
Gelco makes a solid product. But nothing in a flue lasts forever, especially in Deer Park where salt air off the Great South Bay meets freeze-thaw cycles all winter. Here’s what we actually see on Gelco jobs.
- Gelco flexible stainless liners develop pinhole leaks at the corrugation creases. This is the single most common Gelco failure we find in Deer Park homes built in the 1990s and early 2000s. The thin spots in the corrugation flex repeatedly with heat expansion, and after fifteen or twenty winters they give out. We confirm it with camera footage, then pull and replace the liner with a properly sized stainless unit.
- Gelco rigid liner sections separate at the joints. Older Gelco rigid systems were often joined with mechanical fasteners that loosen as the flue expands and contracts. When a joint separates, exhaust gas leaks into the chimney cavity. We see this on townhomes near Deer Park Avenue where original builders cut corners. Our fix is a full reline with a continuous flexible liner, which eliminates interior joints entirely.
- Gelco caps and termination kits crack at the storm collar seal. The cap itself may be fine, but the seal where it meets the clay flue tile breaches. Water gets in, freezes, and spalls the brick at the top of the chimney. We replace the cap, seal it properly with high-temp silicone, and rebuild the top courses of brick if freeze damage already happened.
- Improper shorter liners used in original installations. We regularly pull Gelco liners that were cut too short by the original installer, leaving a gap between the liner top and the chimney crown. The flue gases condense in that gap and eat the mortar. We measure, soak the crown, and install the correct length so the liner terminates at the proper height above the flue tile.
- Aged Gelco liners paired with older terra cotta flue tiles begin to crumble internally. The liner itself may be intact, but the surrounding clay tile is failing. Flue gas escapes through the cracked tile and into the chimney chase. We remove the old tile, inspect the liner with a camera, and if the liner checks out we’ll pour a cast-in-place sealant around it. If the liner is thin, we pull everything and rebuild from the appliance collar up.
Our Gelco Chimney Liner & Rebuild Process
Here’s exactly what happens when you call us about a Gelco liner in Deer Park.
- 1
You call, a person answers. That’s Wendell or a member of the crew, not a call center. We ask what you’re seeing, and if it sounds urgent we schedule a visit within a day or two. No trip charge if you’re in our service county.
- 2
Camera inspection before anything else. We run a camera down the flue and record the whole thing. You’ll see the footage yourself, on the spot. If the liner is fine, we tell you. If it’s not, you’ll see exactly why.
- 3
We give you a written price. One number, no surprises. Most Gelco liner replacements in Deer Park take one day. Partial rebuilds with crown and brick work can stretch to two or three days depending on weather.
- 4
We pull and replace with the right parts. We use quality stainless liners, and on Gelco systems we’ll tell you plainly whether an OEM or aftermarket replacement makes more sense for your flue. We stock what Deer Park homes need most, and for specialty items we’ll have it in hand before we schedule the job.
- 5
We test, we show you, we guarantee it. After the rebuild we run a draft test and a second camera pass. You see the finished result before we pack up. Then the 90-Day Done Right Promise goes on the invoice, in writing.
What Gelco Chimney Liner & Rebuild Costs in Deer Park
Here’s the honest pricing picture for Deer Park homes.
- Gelco liner replacement, standard single-story flue: $1,800 to $2,600
- Gelco liner replacement, two-story or steep-roof access: $2,600 to $3,400
- Partial rebuild, top six courses of brick plus new cap: $1,200 to $2,400
- Full chimney rebuild from the roofline up: $3,500 to $6,500 depending on chimney size, brick match, and roof pitch
- Liner repair (section patch or joint seal, when truly viable): $400 to $800
What moves the price: roof pitch, chimney height, whether your flue can take a round liner or needs an ovalized one for clearance, and whether the crown and brick need work at the same time. We’ll give you a fixed number before the first tool comes off the truck, and that’s the number on the invoice. Call (631) 214-2108 for a free estimate.

FAQs
As an independent Gelco service provider, we can’t speak for Gelco’s warranty department, but most manufacturer warranties cover the liner material itself, not installation or removal labor. The truth is most Gelco liners we see in Deer Park are fifteen to twenty years old and well past any warranty window. If yours is still under warranty, we’ll help you document the failure properly so you can file a claim before we touch anything. Call (631) 214-2108 and we’ll talk it through.
Yes, in most single-story Deer Park homes. We arrive with the right liner length pre-cut, the old liner comes out, the new goes down, we seal and test, and we’re done by the end of the day. Two-story homes with steep roofs can push into a second day if access is tight. We’ll give you a firm timeline when we quote the job.
The camera footage. That’s the one test that doesn’t guess. Before we recommend any liner work, we run a camera down the flue and you watch the screen with us. If you’re seeing signs like a rusty smell in the fireplace, soot stains above the firebox, or white staining on exterior brick, call us. But the camera is what tells us the truth about what’s happening inside.
For most liner replacements, the liner itself is a generic stainless product that works across brands, and we use quality stainless that meets or exceeds the original spec. For Gelco-specific components like caps, drip pans, and termination kits, we source what your chimney actually needs. We’ll tell you the OEM versus aftermarket tradeoffs in plain English before you spend a dollar.
If you’re smelling gas or see smoke backing into the house through the firebox, we treat that as urgent and Wendell or a crew member will be there as fast as the schedule allows, same day whenever we can. For non-urgent liner concerns, we’re typically out within a couple of days. A live person answers the phone around the clock, so you’ll never wait on a voicemail during a scare.
