A Hearthstone company - serving New City, NY

Before & After Gallery - Hearthstone Chimney Co.

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

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

Chimney Cleaning Before & After in New City, NY

We’ve spent over 42 years in Rockland County, and we’ve learned that most homeowners don’t know what their chimney actually looks like inside until something goes wrong. These before-and-after stories show what professional chimney cleaning and repair actually accomplishes. No stock photos, no marketing tricks. Just the work we do in New City, Nanuet, and the neighborhoods we serve.

Stage 3 Glazed Creosote Removal - New City, NY

Thick glazed creosote coating inside chimney flue before professional cleaning
Before: Heavy glazed creosote buildup reducing flue diameter and creating significant chimney fire risk
Clean chimney flue after professional creosote removal
After: Flue restored to full diameter with all combustible deposits removed

The homeowner on South Mountain Road in New City smelled something acrid every time they ran their fireplace, but the fire still drew okay. Our Level-2 camera inspection showed glazed creosote baked onto the flue tiles, a chimney fire waiting to happen. We used rotary cleaning with professional-grade chains and whips to break down the hardened deposits, then ran the camera again so the homeowner could see the bare ceramic. The flue went from roughly 30% obstructed to fully open. Burning season started two weeks later, and they called to say the draft was noticeably stronger.

Chimney Liner Failure and Relining - Nanuet Area, NY

Cracked and deteriorated clay chimney liner before replacement
Before: Deteriorated clay liner with visible cracks and gaps allowing combustion gases to escape
New stainless steel chimney liner properly installed
After: New DuraFlex stainless steel liner with proper insulation and secure top connection

A family near the Nanuet border had been told they needed a full chimney rebuild. Russell Haines ran the camera and found the clay liner was cracked at three joints, but the masonry itself was sound. We installed a DuraFlex stainless steel liner with proper insulation, sized correctly for their fireplace insert. The job took one day. They had heat that evening, and the camera photos showed exactly why we didn’t touch the brick. Done right - and we stand behind it with our 90-Day Done Right Promise in writing.

Chimney Cap and Crown Rebuild - Clarkstown, NY

Deteriorated chimney crown with cracks and missing concrete
Before: Crumbling concrete crown with cracks allowing water infiltration into chimney structure
New properly sloped chimney crown with protective cap installed
After: Poured concrete crown with proper slope and Gelco stainless steel cap for long-term protection

Water was getting into the firebox after every hard rain. The crown was cracked through to the flue, and the old cap was rusted and missing mesh sides. We formed and poured a new concrete crown with a 2-inch overhang and proper slope away from the flue, then topped it with a Gelco stainless steel cap with 3/4-inch mesh. No more water. No more birds. The homeowner in the Clarkstown area told us they’d been putting towels in the firebox for three winters. They won’t need them again.

Fireplace Smoke Chamber Parging - New City, NY

Rough corbeled smoke chamber with gaps and exposed brick before parging
Before: Rough corbeled smoke chamber with gaps causing turbulence and smoke backup into the home
Smooth parge-coated smoke chamber improving draft performance
After: Smoke chamber smoothed with HeatShield cerfractory coating for proper draft and safer operation

This New City fireplace smoked into the living room every time the wind came from the northwest, which is most of winter. The smoke chamber was corbeled brick, rough as a cob, with gaps you could stick your finger into. We parged it smooth with HeatShield cerfractory coating, restoring the proper funnel shape for draft. The difference was immediate. The homeowner said they’d stopped using the fireplace in 2019. They’re using it now.

Chimney Sweep and Damper Repair - Congers, NY

Rusted and stuck chimney damper preventing proper closure
Before: Rusted damper assembly stuck open, wasting heat and allowing debris entry
New energy-top damper installed with proper seal
After: New energy-efficient top-sealing damper with stainless steel cable and proper frame fit

The damper in this Congers home hadn’t closed in years. The homeowner was losing heat up the flue and paying for it. We swept the chimney, removed the rusted throat damper, and installed a new energy-top damper with a stainless steel cable running down to the firebox. It seals at the top, so it stops drafts and keeps animals out. The sweep alone pulled two buckets of soot and a desiccated squirrel nest. The camera inspection afterward showed a clean flue and a damper that actually closes. A square deal: no surprises on the bill.

Prefabricated Fireplace Panel Replacement - Rockland County, NY

Cracked refractory panels in prefabricated fireplace before replacement
Before: Cracked and deteriorated refractory panels in factory-built fireplace creating fire hazard
New properly fitted refractory panels installed
After: New professional-grade refractory panels fitted and sealed for safe fireplace operation

The refractory panels in this prefab unit were cracked through the middle, exposing the metal firebox to direct flame. That’s a house fire risk, and it’s more common than people realize in Rockland County homes built in the 1980s and 90s. We sourced the correct replacement panels, fitted them with proper clearances, and sealed the joints with refractory cement. Most jobs like this we complete in a single visit. The homeowner watched the camera inspection, saw the cracks for themselves, and understood exactly why we recommended the work. Photos you can see, a plain-English verdict.
