Creosote Removal & Chimney Fire Prevention in Monsey & 30 miles around

What this service actually is

Creosote comes in three stages. Stage one brushes off. Stage two is crunchy and flaky. Stage three is glazed, tar-like and hard as glass — and it is the reason chimney fires reach 2,000°F. Standard brushing will not touch stage three. We use rotary chain systems and professional-grade catalytic treatments to break it down and take it out.

What you get

• Removal of stage 2 and stage 3 glazed creosote that brushes cannot touch
• Rotary chain and whip heads sized to your flue
• Professional catalytic modifier treatments for heavy glazing
• Post-removal camera inspection to confirm the flue is genuinely clear
• Burn coaching so it does not build back up the same way

How we do it

1. Assess the stage

Camera first. Stage 1 is a normal sweep; stage 3 needs a different tool and an honest conversation about cost.

2. Break it down

Catalytic treatment applied and burned or dwelled per protocol to make the glaze brittle, then rotary chain removal.

3. Verify and protect

Second camera pass to confirm removal, then a liner condition check — chimney fires often crack tiles even when nothing visible happened.

Signs you need creosote removal

If any of these sound familiar, it is worth a call. There is no charge to ask.

• Shiny, black, tar-like coating visible above the damper
• A loud roaring, popping or "freight train" sound during a fire
• Dense black smoke or flames visible from the top of the chimney
• Burning unseasoned or wet wood all season
• Frequent slow, smoldering, damped-down fires

What it costs

Creosote Removal & Chimney Fire Prevention typically runs $249 – $650 for a standard single-family home in our service area, and takes about 2–4 hours. The variables that move that number are roof access, flue height, how many flues share the stack, and condition.

“Glass was black and the pilot kept dropping. Turned out the logs had been placed wrong since installation. Cleaned, reset, tested. Looks like a real fire again.”

Why homeowners pick Hero

We are a family company working out of Monsey, not a national franchise routing your call to a dispatcher three states away. That means the person who quotes your job is on the roof doing it, the price does not change halfway through, and if something is not right afterward we are twenty minutes away.

Every visit includes photo documentation. Every recommendation comes with an explanation of what happens if you wait, so you can make the call on your own timeline instead of ours.
