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.

AfterAnnual Sweep in Northport, NY
An annual chimney sweep removes the creosote, soot, and debris that accumulate in your flue every heating season – typically taking under two hours and leaving your fireplace ready to burn cleanly and safely. For most Northport homeowners burning wood regularly through a Long Island winter, once a year is the minimum the National Fire Protection Association recommends, and it’s the schedule we’ve built our service around for over 42 years. If you’d like to get on the calendar, call us at (631) 528-2501 – a live person will pick up.
Hearthstone Chimney Co. handles annual sweeps as part of our broader Chimney Cleaning & Sweep in Northport service. That means when our technician shows up, he’s not just running a brush through your flue and leaving. He’s doing a methodical inspection at the same time, photographing what he finds, and giving you a plain-English verdict before he packs up. You’ll know exactly what condition your chimney is in – not because we told you so, but because you’ll see the photos yourself.
Northport’s mix of older Colonials and Cape Cods, many of them built in the 1950s through 1970s, means we see a lot of original clay-tile liner systems that are quietly degrading. The salt air off Northport Harbor accelerates mortar wear on exterior chimneys. Trees – and Northport has no shortage of mature oaks and maples – drop leaves, twigs, and seed pods into open flues throughout the fall. A sweep that skips a real inspection misses all of this. We don’t skip it.
When You Need an Annual Sweep
- You burned wood last season. A cord of hardwood – typical for a Northport household heating through December to March – produces enough creosote to warrant a full cleaning before the next season starts. Even a light coating at the wrong moisture level is a fire hazard.
- You haven’t used the fireplace in a year or more. Dormant flues attract nesting birds and squirrels, and Northport’s proximity to wooded areas along the harbor and Centerport border means this is more common than you’d think. A sweep clears blockages before your first fire.
- You’re noticing smoke backing into the room. Poor draft is sometimes a fireplace geometry problem, but more often it’s a partially blocked flue. We’ve traced this to everything from accumulated creosote to a raccoon den – both are fixable.
- There’s a smoky or musty odor even when the fireplace is cold. This usually means creosote residue is being activated by summer humidity. On a humid July day on the North Shore, a dirty flue makes itself known through the whole first floor.
- You bought the house recently. The previous owner’s sweep history – if there was one – rarely transfers with the deed. We see homes in Northport’s Mill Dam Road and Makamah Beach neighborhoods change hands with flues that haven’t been touched in a decade.
- Your last sweep was more than 12 months ago. The calendar is the simplest trigger. NFPA 211 is clear: annual inspection and cleaning for any fireplace in active use. If you’re past that window, call and we’ll schedule it.
Our Annual Sweep Process
- Pre-sweep walkthrough and prep. The technician introduces himself, walks through what he’s going to do, and lays drop cloths over your hearth and surrounding floor. Nothing about your living room gets dusty. We’ve been doing this long enough to know the small things matter to the people who’ve lived in a house for thirty years.
- Level-2 camera inspection of the flue. Before the brush goes in, we run a camera top to bottom. This documents the condition of your liner, the mortar joints, any cracking, and any obstructions. You see the same images we do – no guessing, no taking our word for it. We find problems in this step that a brush-only sweep would miss entirely, including hairline cracks in clay tile liners common in Northport homes built before 1970.
- Full flue brushing and vacuuming. We clean from the top down using professional-grade brushes sized to your specific flue dimensions, with a HEPA-rated vacuum capturing the debris as it falls. Creosote comes in three stages of hardness – Stage 1 is powdery soot, Stage 2 is tarry flakes, Stage 3 is glazed and requires chemical treatment before brushing. We identify which stage you have and clean accordingly.
- Firebox and smoke chamber cleaning. The firebox shelf, smoke shelf, and damper assembly collect debris that the flue brush doesn’t reach. We clean these manually. The smoke shelf in particular traps everything from soot to bird nesting material, and a clogged smoke shelf is a direct cause of poor draft.
- Post-clean inspection and photo review. Once the flue is clean, we run the camera again if needed to confirm the result, then sit down with you and go through the findings. If we found something – a cracked tile, deteriorating mortar, a damaged damper – we document it in writing and give you a plain-English explanation of what it means and what it would take to fix it. No pressure, no upsell theater. If it needs attention, we say so. If it doesn’t, we say that too.
- Final walkthrough and written report. You get a written summary of what was done, what was found, and the condition of your chimney system. Everything is covered by our 90-Day Done Right Promise – if something wasn’t done correctly, we come back and make it right. That’s in writing, no arguing, no phone-tag.
Annual Sweep Pricing in Northport
A standard annual sweep for a single-flue wood-burning fireplace in Northport typically runs in the range below. Prices reflect the Long Island market and the fact that older homes in this area often need more time and care than a newer construction with a straight, clean liner.
| Service | Typical Range |
|---|---|
| Standard annual sweep (single flue, wood-burning) | $175 – $275 |
| Sweep with Level-2 camera inspection included | $225 – $325 |
| Sweep with Stage-2 or Stage-3 creosote treatment | $275 – $450+ |
| Oil or gas flue sweep (different debris profile) | $150 – $250 |
| Second flue in the same visit | Add $100 – $175 |
A few factors move the number in either direction. Flue height matters – a three-story chimney on one of Northport’s hillside properties takes longer to clean than a standard two-story run. Heavy creosote buildup from burning green or unseasoned wood adds time and sometimes requires a chemical loosening agent before brushing. And if the inspection turns up a repair need – a cracked liner section, a failing damper – we’ll quote that separately with no obligation to proceed that day.
Our $89 Seasonal Tune-Up is a good fit if your fireplace is gas-burning or sees very light use. We also offer $50 Off Any Repair Over $250 and a permanent 5% discount for seniors and veterans. If you’ve already gotten a written estimate from another company, call us for a free second opinion – we’ll give you our honest read on it.
The number on our estimate is the number on the invoice. No add-ons at the door, no materials that appeared after the job started.

Why Northport Homeowners Call Hearthstone
We’ve been doing this since 1984 – longer than some of the houses we service have had their current owners. That’s not a boast; it’s a way of saying we have no reason to cut corners. A company that plans to be in Northport in another thirty years acts accordingly. We use professional-grade materials from brands like Olympia Chimney and HeatShield when repairs are needed – not builder-grade substitutes that fail in three seasons.
Every technician is background-checked and shows up in uniform. Most jobs finish in a single visit. The phone is answered by a live person around the clock, every day – not a voicemail that routes to a callback queue. Russell Haines has built this company around the idea that a homeowner who trusts you with their chimney should be able to reach a real person when they call. That hasn’t changed in four decades.
The 90-Day Done Right Promise covers every sweep we perform. If the work wasn’t done right, we come back and make it right – that’s the commitment, in writing, with no arguing. We call it the K.E.Y.S. values code internally: Krafted right, Every time, Your home first, Standing behind it. It shapes how every job gets done, including a routine annual sweep.
For homeowners in Northport who’ve been burned by a contractor before – and a lot of you have – this is the point. You call once, we show up when we say, we do what we said we’d do, and you have it in writing if anything falls short. That’s the deal.
FAQs – Annual Sweep in Northport
How often does a chimney need to be swept in Northport?
Once per year is the NFPA 211 standard for any wood-burning fireplace in active use, and it’s the right baseline for most Northport homes. If you’re burning more than a cord of wood per season or you have an older clay-tile liner, a mid-season check isn’t excessive. Gas fireplaces accumulate different debris and should be inspected annually even if they don’t need a full sweep every time. Call us at (631) 528-2501 if you’re not sure where your system falls.
Is it safe to sweep the chimney myself?
The brushing itself is possible as a DIY task, but the inspection is not something a homeowner can do safely or reliably on their own. Creosote at Stage 2 or 3 is a fire hazard that requires professional-grade treatment, and a cracked liner in an older Northport home can expose framing materials to heat and combustion gases without any visible sign from the firebox. A sweep without a camera inspection misses the things most likely to cause a house fire. We’d rather be direct about that than soft-pedal it.
What’s the difference between a sweep and an inspection?
A sweep removes the accumulated material – creosote, soot, debris, nesting material – from the flue. An inspection assesses the structural condition of the chimney system: the liner, mortar joints, cap, crown, and firebox components. We combine both in our standard annual sweep visit, and we document the inspection with camera photos you can see. A sweep without an inspection tells you the flue is clean; it doesn’t tell you whether the liner is cracking or the crown is letting water in.
How long does an annual sweep take?
Most single-flue sweeps in Northport run between 90 minutes and two and a half hours. The range depends on flue height, the level of buildup, and whether we find anything during the camera inspection that warrants a closer look. We arrive with everything needed to complete the job in one visit. You won’t be waiting for a second appointment to finish what we started.
