Chimney Sweep Services

Chimney Sweep Services cover the full mechanical brushing of your flue liner, the smoke chamber, and the firebox, removing the creosote and soot that accumulates every time you burn wood. Hempstead homes with active fireplaces need this at least once a year, and homes with oil-fired heating systems should have the vent connector swept on the same schedule. Our standard sweep in Hempstead runs $189 to $349, and that price is locked in writing before we start.

Creosote Removal

Creosote is the tar-like residue that condenses on flue walls as wood smoke cools. Stage one creosote brushes out easily. Stage three creosote has hardened into a glaze that requires specialized rotary tools, and it’s the leading cause of chimney fires we see in older Hempstead homes. We’ll tell you which stage you’re dealing with and show you before-and-after photos so you know exactly what was removed.

Flue Brushing and Vacuum Inspection

We use dual-line HEPA-filtered vacuums throughout the job, so soot never ends up on your furniture or carpet. After brushing, we run a camera down the flue to confirm the walls are clean and to flag any cracks, gaps, or deterioration that need attention. You get a written report with photos, not a verbal summary.

Chimney Cleaning

Chimney Cleaning is the physical removal of combustible deposits from the interior of your chimney, and it’s the single most effective step you can take to prevent a chimney fire. Any East Meadow or Hempstead homeowner who burns more than a cord of wood per season should plan on two cleanings: one in early fall and one mid-winter if you use the fireplace heavily. Flint Chimney Co Hempstead performs a full mechanical sweep with wire or poly brushes sized to your specific flue dimensions, then documents the result.

Wood-Burning Flue Cleaning

Wood fires produce the most creosote, especially when you burn green or unseasoned wood. We see accelerated buildup in Hempstead homes that burn pine or construction scraps, and in flues that run through unheated exterior walls. Our cleaning removes deposits from the cap all the way down to the firebox floor.

Oil Furnace Flue Cleaning

Oil-fired furnaces and boilers vent through the chimney too, and they produce sulfur-based soot that flakes off the flue walls and can block the vent. A blocked oil flue sends carbon monoxide back into the house. We brush these flues the same way we do fireplace flues, and we check the barometric damper and cleanout door as part of the service.

Fireplace Cleaning

Fireplace Cleaning includes the firebox itself, the damper assembly, the smoke shelf behind the damper, and the visible masonry around the opening. Uniondale and Hempstead homeowners often vacuum out the firebox themselves but miss the smoke shelf, where creosote and debris collect invisibly. Our service covers the complete firebox interior, from the hearth floor to the throat of the flue, typically included in the same $189 to $349 range as the full sweep.

Firebox and Smoke Shelf Cleaning

The smoke shelf sits just above the damper and catches ash, creosote, and even bird nesting material. It’s one of the most neglected areas in residential chimneys, and it’s a common source of the smoky smell that drifts into the house during humid summers. We remove everything from this area during every cleaning and show you the difference in the photo report.

Damper Service and Cleaning

A damper that won’t open fully or won’t seal shut wastes heat and can spill smoke into the room. We clean the damper track and plate, check the hinge operation, and let you know if it should be replaced. A properly functioning damper also keeps conditioned air from escaping up the chimney all summer long.

Chimney Services

Chimney Sweep Maintenance Checklist for Hempstead Homeowners covers the basics, but Chimney Services is the umbrella term for everything we do beyond the basic sweep: inspections, repairs, relining, waterproofing, cap installation, and masonry work. Our Hempstead customers call us most often for level 2 camera inspections after a chimney fire or before buying a home, and for crown repairs after winter freeze-thaw cycles. A standard sweep is $189 to $349, while inspections and repairs are quoted individually in writing before any work begins.

Camera Inspections

We run a high-resolution camera through the entire flue and record everything. That recording is yours to keep, which means when we recommend a repair, you can see the crack or gap with your own eyes before deciding. This is how Flint Chimney Co Hempstead earns trust: evidence first, recommendation second, and no recommendation ever without footage to back it up.

Repairs and Relining

When a flue liner has cracked or separated, we quote the repair option that fits the job. For minor gaps, HeatShield’s cerfractory sealant system can restore liner integrity without a full replacement. For severely damaged flues, we install a new stainless liner, typically DuraFlex or an Olympia Chimney product, sized to your appliance. Every repair carries our 365-Day Done Right Promise in writing.

Chimney Sweep Certified

Chimney Sweep Certified means the technician working on your chimney has completed formal training through a recognized chimney industry program and maintains that credential through continuing education. Flint Chimney Co Hempstead dispatches certified, background-checked technicians on every call, and Hank Delano personally reviews every inspection report our Hempstead crew files. Homeowners should ask any chimney company for proof of certification before letting someone onto the roof.

What Certification Actually Covers

A certified sweep understands draft dynamics, clearance-to-combustibles codes for Nassau County, and the specific failure patterns of masonry and prefabricated chimneys. Certification matters most when we’re evaluating whether a flue is safe to use, not just when we’re cleaning it. We’re trained to identify clearance violations and improper installations that untrained eyes miss.

Why It Matters for Your Home Insurance

If you ever have a chimney fire and file a homeowners insurance claim, your insurer will ask for documentation of cleaning and inspection. A certified sweep’s report with dated photos is exactly what they’re looking for. We provide that documentation on every job, not just when you ask for it.

Gas Fireplace Cleaning

Gas Fireplace Cleaning removes the dust, pet hair, and mineral residue that accumulate on the glass, logs, burner, and pilot assembly of vented and ventless gas units. Hempstead homeowners often assume gas fireplaces don’t need service, but the burner ports clog with household dust and the glass fogs with a white film that won’t wipe off. A gas fireplace cleaning typically runs $149 to $229 as an add-on or $189 to $289 as a standalone visit, quoted in writing before we begin.

Log and Burner Cleaning

We remove the log set, clean each log individually, and clear the burner ports with compressed air so the flame pattern returns to what the manufacturer intended. A burner that’s partially clogged burns unevenly and produces more soot on the glass. Most gas fireplace owners in Hempstead have never had this done, and the difference in flame quality is immediately visible.

Glass and Pilot Assembly Service

We clean the glass with a non-abrasive cleaner that won’t etch the ceramic, and we inspect the gasket that seals the glass to the firebox. The pilot assembly gets cleaned and tested for proper thermopile voltage so the unit lights reliably on the first click. If we find a failing component, you get a written quote before we replace anything.

Chimney Maintenance

Chimney Maintenance is the ongoing care that keeps your chimney safe and efficient between full cleanings: waterproofing, cap and crown inspection, flashing checks, and seasonal tune-ups. Hempstead’s coastal weather means chimneys here take more abuse than inland chimneys do, and a simple maintenance visit each fall catches small problems before they become expensive ones. A maintenance tune-up typically runs $129 to $199, and it’s the smartest dollar you can spend on your chimney.

Seasonal Tune-Ups

Every fall, we recommend a tune-up that includes a visual inspection of the cap, crown, flashing, and interior flue, plus a light brushing if needed. This is the visit that catches cracked crowns before winter freeze-thaw cycles turn them into full masonry failures. Hempstead homeowners who do this every September almost never face mid-winter chimney emergencies.

Waterproofing and Crown Sealing

Masonry chimneys absorb water, and water is what destroys them from the inside out. We apply vapor-permeable waterproofing treatments like those from Gelco and other trade brands that let the masonry breathe while keeping rain out. Combined with a proper crown seal, this extends the life of your chimney by years, and we’ll quote it separately so you know exactly what it costs.

Brands We Service

We work with professional-grade chimney materials across every major trade brand, and we specify products by job requirements, never by margin. DuraFlex stainless steel liners are our go-to for wood-burning relining jobs because their flexibility handles offset flues without cutting corners. We’ve installed and serviced hundreds of DuraFlex systems throughout Nassau County, and we stock the connectors and terminations to match.

HeatShield’s cerfractory sealant is what we reach for when a flue has minor gaps or joint failures that don’t warrant a full liner replacement. It restores a continuous, gas-tight surface inside the existing flue and carries its own manufacturer’s documentation. Whether you have an Olympia Chimney cap, a Famco termination, or any other make on your roof, we can service it.

Signs You Need a Pro Right Now

• You smell smoke or soot inside the house, even when the fireplace isn’t lit. This usually means the flue isn’t drafting properly or the chimney is partially blocked. It can also indicate a buildup of creosote that’s off-gassing into the living space. Don’t ignore the smell; call us at (516) 559-6922 and we’ll identify the source.
• You see dark, shiny residue on the flue walls or damper. That’s stage two or three creosote, and it’s fuel for a chimney fire. A flashlight and a mirror will show you the first few feet of flue from inside the firebox. If it’s thick or glossy, the chimney needs a professional cleaning before the next fire.
• Your gas fireplace flame is yellow or uneven, or the glass is heavily filmed. A healthy gas flame is blue and steady across the burner. Yellow flames indicate clogged ports or combustion problems, and a white or gray film on the glass means the unit hasn’t been serviced in years. Both are signs that a full cleaning is overdue.
• Birds, squirrels, or other animals have been near your chimney. Hempstead’s older homes often have uncapped or damaged chimneys, and nesting material is one of the most common causes of chimney fires and carbon monoxide backup. If you hear scratching or chirping, or you see twigs at the base of the firebox, we need to inspect and cap the flue.
• Water stains on the ceiling or walls near the chimney. This points to a failed crown, flashing, or masonry joint that’s letting water in. In Hempstead’s freeze-thaw winters, that water expands when it freezes and cracks the chimney from the inside. A camera inspection will show you exactly where the water is entering.

Our Process, Step by Step

1. 1
   You call and get a live person. Our phones are answered 24/7 by a real human being, not a voicemail tree. We take down the details of your chimney and fireplace setup, answer your questions, and book a window that works for you. We give you a written price quote for the standard service before we ever arrive.
2. 2
   We arrive in uniform and protect your home. Our technicians are background-checked, and they lay down drop cloths from the entry door to the fireplace before any work starts. We use HEPA-filtered vacuums running the entire time, so dust doesn’t migrate through your house. You’ll know exactly who’s in your home and what they’re doing.
3. 3
   We sweep, brush, and vacuum every surface that needs it. The flue gets mechanically brushed with the right-sized tool for your dimensions. The smoke shelf, damper, and firebox get fully cleaned out. If you have an oil furnace using the same flue, we brush that too. Nothing gets skipped.
4. 4
   We camera the flue and document everything. Before we pack up, we run the inspection camera through the full length of the chimney and record the footage. You’ll see the result with your own eyes and get a written report with photos. If we find something that needs repair, you get a written quote for that separately.
5. 5
   We review everything with you and stand behind it. Hank Delano or your technician walks you through what was found, what was done, and what (if anything) you should do next. Every repair we perform carries the 365-Day Done Right Promise: if a covered repair fails within one year, we return and fix it at no charge.
