Nesconset isn’t a town that tolerates shortcuts. The homes here, mostly built during the 1960s and 1970s suburban boom along Gibbs Pond Road and the surrounding blocks, have chimneys that are now 50 to 60 years old. That uniform age means we’re seeing the same problems across entire neighborhoods: clay tile liners cracked from decades of oil-burner exhaust, mortar joints opened by Suffolk County freeze-thaw cycles, and flues that haven’t been inspected since the original owner moved in. We know these houses because we’ve worked on hundreds of them. Our Chimney Cleaning & Sweep team treats every chimney like the structural system it is - not just a hole in the roof.
Why Hearthstone Chimney Co. Is Nesconset’s Preferred Chimney Cleaning & Sweep Company
We’ve been driving to Nesconset since the early 1980s, back when Smithtown Boulevard was still the main artery and the Nesconset Fire Department’s original building stood where longtime residents remember it. That longevity matters. A company that plans to be here in thirty more years doesn’t gamble with its reputation on a single job.
Our Nesconset customers tend to be homeowners who have lived in the same house for twenty or thirty years. They’ve seen contractors come and go. What they tell us they value is the documentation: every Level 2 inspection ends with photos they can see on the technician’s tablet and a plain-English verdict written in sentences, not code. No surprises, no arguing, no paperwork shuffle if something needs follow-up.
Calls are answered by a live person, 24 hours a day, 7 days a week. Not an app. Not a callback list. A human being who can schedule your sweep or send a technician if you’ve got smoke backing up into the living room.
Our technicians are background-checked, uniformed, and carry professional-grade equipment from brands like HeatShield and Olympia Chimney. Most jobs are completed in a single visit, with no-hassle upfront pricing - the number on the estimate is the number on the invoice. And everything we do is backed by our 90-Day Done Right Promise: in writing, no arguing, if it’s not right, we come back.
Our Chimney Cleaning & Sweep Services in Nesconset
Level 1 Inspection
A Level 1 inspection is the baseline for any Nesconset home with a chimney that hasn’t changed - same appliance, same fuel type, same use. We examine the readily accessible portions of the chimney exterior, interior, and connecting appliances. For the typical Nesconset ranch or split-level on a street like Southern Boulevard or Browns Road, this means checking the crown, the flue opening, and the firebox for creosote buildup, obstructions, or structural deterioration. A Level 1 inspection in Nesconset runs $189-$249 and includes the sweep if needed.

Level 2 Inspection
Level 2 is what we recommend for most Nesconset homes, and for good reason. If you’ve converted from oil to gas, bought the house, or noticed any change in performance, this is the inspection that tells you what’s actually happening inside the flue. We run a camera the full length of the chimney, document every crack, glaze, or gap in the clay tile liner, and give you photos you can see plus a plain-English verdict. In Nesconset, where oil-to-gas conversions have left countless abandoned flues deteriorating unseen, this inspection has revealed serious safety issues in homes where the fireplace “seemed fine.” Level 2 inspection with camera documentation runs $289-$349.

Creosote Removal
Creosote is the reason sweeping exists. It’s a combustible deposit that builds up in layers - flaky, puffy, or glazed - depending on how you burn and what you burn. Nesconset’s older masonry chimneys, with their original clay liners, are particularly vulnerable because uneven liner surfaces trap creosote in ridges that a basic brush won’t touch. We use professional-grade rotary systems and, when necessary, chemical treatments to break down glazed creosote that has hardened to a varnish-like finish. Heavy creosote removal in Nesconset typically adds $75-$150 to the base sweep price, depending on thickness and accessibility.

Soot Removal
Soot is the lighter, powdery cousin to creosote, but it carries its own problems. In Nesconset homes with abandoned oil-burner flues, we frequently find thick soot deposits combined with sulfur residue that has eaten away at the liner surface. This isn’t just a cleaning issue - it’s a warning that the flue may be compromised. Our soot removal process includes HEPA-contained vacuuming to protect your home’s air quality, and we always inspect the underlying liner condition before declaring the job complete. Standard soot removal is included in our base sweep; heavy accumulations in neglected flues may require additional treatment at $95-$175.
We also handle Chimney Repair in Nesconset when inspection reveals damage beyond what cleaning can address, and Fireplace Services in Nesconset for homeowners looking to restore or upgrade their hearth.

Trusted Brands We Service in Nesconset
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from HeatShield, Gelco, and Famco - brands that hold up to Suffolk County’s coastal humidity and freeze-thaw punishment. When a Nesconset homeowner needs a new cap, a liner repair, or a crown seal, we install what we’d put on our own house. Because we stock common parts and materials locally, most repairs that surface during a sweep can be completed same-day without a return trip or a two-week wait for shipping.
Common Chimney Cleaning & Sweep Problems We See in Nesconset Homes
- Abandoned oil-burner flues left open to the weather. After gas conversion, many Nesconset homeowners never capped or inspected the old flue. Rain enters through cracked crowns, freezes in winter, and slowly destroys the chimney from inside the chase - a problem we find repeatedly in the Gibbs Pond Road corridor and surrounding 1960s developments.
- Glazed creosote from decades of wet wood burning. Long Island’s damp winters mean homeowners often burn wood that hasn’t seasoned properly. The result is a shiny, tar-like creosote layer that standard brushing won’t remove and that poses a genuine fire hazard.
- Spalled brick and open mortar joints from freeze-thaw cycles. Suffolk County temperatures oscillate around freezing dozens of times each winter. Water enters microscopic cracks, expands, and opens joints that were tight in October. By March, the chimney is shedding brick faces and leaking into the attic.
- Shared flue configurations with deteriorating separation. Nesconset’s original builders often ran fireplace and oil-burner flues through the same chase with only a thin tile partition. After fifty years, that partition cracks, allowing cross-contamination of gases and creating a path for chimney fires to spread between flues.
