Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Flint Chimney Co Hempstead Is Freeport’s Preferred Chimney Sweep Company
Freeport homeowners call us because we put a price in writing before a single tool comes off the truck. That’s not a marketing line. It’s how we operate under the Garrison Standard, the same code every Garrison Partners location follows. We’ve been part of that family since 2002, and our owner Hank Delano holds every technician to the same rule: the number you approve is the number you pay.
Our technicians are background-checked and uniformed, so when we show up at a home off South Ocean Avenue or in the neighborhoods around Lakeview Avenue, you know exactly who’s walking through the door. And when you call us at night or on a weekend, a live person answers. Not a voicemail tree. Not a callback form. That matters when you’re staring at a damp, smoky fireplace in January and you just want a straight answer about whether it’s safe to use.

Chimney Maintenance in Freeport
Chimney Maintenance is the routine care that keeps a Freeport chimney working safely between sweeps, and it’s where we catch problems before they turn into $3,000 rebuilds. Around here, that means checking the crown for spalling, looking at the mortar joints, and making sure the damper still opens and closes. A maintenance visit in Freeport typically runs $149 – $249 on its own, but it’s often folded into an annual sweep. The point is simple: you don’t want to find out your crown has been quietly absorbing salt and rain for five years by watching water run down your living room wall.
Flashing and Crown Checks
On Freeport’s older homes, especially the pre-WWII stock around the south village, the chimney crown is usually the first thing to go. Salt-laden air accelerates the freeze-thaw cycle, cracking the crown and letting water into the brick. We inspect the crown and flashing on every maintenance call and tell you plainly if it can wait or if it needs work now.
Damper and Cap Service
Dampers rust fast near the water. We regularly replace frozen or rusted dampers with Famco units, and we check chimney caps for rust-through. A cap that’s rotted out lets rain, leaves, and even birds into the flue, and that organic material is exactly what creosote clings to.
Chimney Sweep Services in Freeport
Chimney Sweep Services in Freeport are more than just brushing soot. When we sweep a chimney here, we’re also looking at what the salt air and the house’s age have been doing to the flue. A basic sweep in Freeport runs $189 – $289. If we’re dealing with third-degree creosote, a glazed, tar-like buildup that’s common when older chimneys draft poorly, the job takes longer and typically lands between $325 and $450. Every sweep includes a visual check of the firebox, damper, and accessible flue, and we photograph what we find so you can see it.
Creosote and Soot Removal
Creosote is the unburned fuel that condenses on the flue walls. In a Freeport home with a cold, unlined chimney, it builds up faster because the smoke cools quicker on its way up. Soot removal keeps the firebox and smoke chamber clear so the fire drafts properly, and it’s a standard part of every sweep we do.

Annual Sweep for Wood-Burning Fireplaces
If you burn wood more than a couple times a week between October and March, the National Fire Protection Association standard is a yearly sweep. Freeport’s humid summers don’t pause creosote buildup, they just bake it harder onto the flue walls. An annual sweep costs the same as any standard cleaning and keeps you ahead of the tar glaze that’s genuinely difficult to remove.

Trusted Brands We Service in Freeport
We work with professional-grade chimney products from Olympia Chimney, Famco, and Copperfield because we won’t install parts that fail in Freeport’s salt air within a season or two. When we stock dampers, caps, and chase covers, we choose materials specified for coastal conditions. That means when a Freeport chimney needs a new damper or a crown seal, we’re not ordering something generic from a supply house three states away. We’re installing components built to hold up near the water. You can verify those brand names independently, and we encourage you to. If a company quotes you a repoint with unnamed materials and no written guarantee, that’s your answer.
Common Chimney Sweep Problems We See in Freeport Homes
- Third-degree creosote glaze in unlined flues. Pre-WWII Freeport chimneys often have no clay tile liner at all, or the tiles have shifted. That means smoke cools fast, condenses, and leaves behind a tar glaze that’s genuinely difficult to remove and is a fire hazard.
- Spalling brick on the south side. The salt spray from the bay works on the outer brick face. We see efflorescence and face-spalling in Freeport chimneys decades earlier than in, say, Baldwin or Merrick, where the air is less saturated.
- Rusted dampers and caps. Constant moisture from the Atlantic air corrodes damper frames and cap screens. A damper frozen open is a heat loss in winter and a bird entry in spring.
- Hidden liner cracks that sweep-only companies miss. Salt-corrosion widens hairline cracks in clay tile liners. The only way to see that is with a Level 2 camera inspection, which is why we push for it on pre-WWII chimneys.
On a 1920s Dutch Colonial off South Main Street near the water, our crew found a clay-tile flue with third-degree creosote glaze and a rusted Famco damper frozen open, plus a chimney crown cracked from freeze-thaw spalling. We camera-scoped the smoke chamber, removed the tar glaze with a rotary whip, replaced the damper, and applied a breathable crown seal, then showed the homeowner the before/after footage so they could see exactly why each step was necessary. That’s the discipline we bring to every chimney in Freeport.

FAQs About Chimney Sweep in Freeport
Salt-laden air from the Atlantic settles on the brick and mortar of your chimney, and every rain rehydrates the salt crystals, which then expand and contract with freeze-thaw cycles. That pressure spalls the brick face and opens hairline cracks in the crown and mortar joints. Between cleanings, that’s what’s quietly happening. An annual sweep in Freeport is also an annual chance to catch that damage before it becomes a rebuild. Call (516) 559-6922 for a free estimate.
You don’t need a liner just to have the chimney swept. What you need is for us to camera-scope the flue and see what condition the masonry is actually in. If the clay tiles are cracked, shifted, or missing and we’re seeing heat transfer or flue gases in the wall cavities, then a liner is a genuine safety recommendation, and we’ll show you the footage. If the flue is intact, we’ll tell you that too and put it in writing. Nothing is recommended without camera evidence you can see.
A sweep is removing soot and creosote from the flue and smoke chamber. A Level 2 inspection is a camera scope of the entire flue system, from the firebox to the crown, looking for cracks, voids, and hidden damage. For any Freeport chimney built before 1940, especially one that’s been breathing salt air for 80-plus years, a Level 2 is worth the extra cost because it finds the liner cracks that salt corrosion widens over time. A sweep alone can’t see those.
Most likely because the previous seal was a surface coating, not a breathable crown repair, and because the root cause, salt-laden air accelerating freeze-thaw spalling, was never addressed. A proper crown repair in Freeport means rebuilding the crown with a correct slope, an overhang, and a breathable seal that lets moisture escape rather than trapping it. If someone just painted a sealant over a spalled crown, it fails within one or two seasons. We’ll show you the before and after.
Third-degree creosote, the hard, tar-like glaze, can often be removed with a rotary whip system, though it takes longer and costs more than a standard sweep. Whether you also need a new liner depends on what the camera shows underneath the glaze. If the liner is cracked or deteriorated, cleaning it is a temporary measure, not a fix. We’ll scope it first, show you the footage, and then give you a written quote. Call (516) 559-6922 for an exact quote, estimates are free.
