Our Fireplace Services in Demarest
Wood Burning Fireplace Service
Demarest’s post-WWII housing stock - colonials, capes, and split-levels built 1945 to 1975 - was never designed for the fireplace use patterns of today. Original multi-flue masonry chimneys were sized for oil-fired boilers, then adapted for wood-burning inserts during the 1970s energy crisis. That conversion sequence left mismatched clay-tile liner diameters and deteriorating mortar joints that trap creosote.
We clean and inspect these systems with the understanding that Demarest’s heavy oak and tulip poplar canopy compounds the problem. Leaf debris and squirrel nests block flues on homes where owners say they “barely use the fireplace.” Our cleaning includes a camera inspection of the full flue length, and we’ll show you what we find.
Gas Fireplace Service
Gas fireplace conversions are common in Demarest, but the work isn’t always done to current safety standards. Undersized liners, improper venting through old oil-boiler chimneys, and missing termination caps create carbon monoxide risks we find regularly on the East Hill and in the neighborhoods below the ridge.
Our $89 Seasonal Tune-Up covers burner inspection, thermocouple testing, gas-pressure verification, and a draft-performance check. If your pilot light won’t stay lit or you’re getting soot staining, we’ll diagnose the root cause - not just swap parts.
Fireplace Insert Installation & Service
Inserts transform drafty masonry fireplaces into efficient heat sources, but installation in Demarest’s older chimneys demands attention to liner sizing. The Palisades escarpment’s downdraft tendency means an insert without proper chimney relining can actually worsen smoke spillage.
We size every insert to the flue using DuraFlex stainless steel liners, and we top the chimney with downdraft-resistant caps engineered for ridge conditions. The result: heat output you can measure, and a system that draws properly even when the wind hits the Palisades wrong.
Damper Repair & Replacement
A stuck or rusted damper wastes heat and invites downdraft problems. In Demarest, we see dampers frozen solid from moisture infiltration through cracked crowns - freeze-thaw damage accelerated by the exposed, shallow-soil conditions on hillside lots. We repair throat dampers and install top-sealing dampers that close at the chimney crown, stopping heat loss and animal entry simultaneously.
Trusted Brands We Service in Demarest
We stock parts and materials from professional-grade brands: DuraFlex stainless steel liners, HeatShield cerfractory flue resurfacing, and Gelco chimney caps and accessories. No builder-grade substitutes. For Demarest homeowners, this means faster turnaround - most repairs complete in one visit because the right part is already on the truck. We also source from Olympia Chimney, Famco, and Copperfield when a specific application demands it.
Common Fireplace Services Problems We See in Demarest Homes
- Cracked crowns and spalled brick from freeze-thaw on exposed Palisades lots. Bergen County winters hit Demarest’s elevated chimneys harder than valley homes. Frost penetrates masonry faster on shallow, rocky soil, turning routine cleaning calls into necessary repair consultations before heating season.
- Downdraft from ridge wind-shadow causing smoke spillage. Even with a functional damper, Demarest’s escarpment location creates negative pressure that pushes smoke into living rooms. Standard chimney caps often make it worse. We size and install downdraft-resistant caps specifically for this terrain.
- Blocked flues from leaf debris and squirrel nests in mature tree overhangs. Demarest’s dense canopy is beautiful and problematic. Technicians regularly find complete blockages in flues homeowners assumed were clear because the fireplace sees light use.
- Mismatched clay-tile liners from oil-to-gas conversions. The typical Demarest chimney served an oil boiler originally, then got retrofitted for gas or wood without proper relining. Undersized tiles crack from thermal shock and accelerate creosote buildup or venting failure.

On a recent call in the East Hill neighborhood, we serviced a 1960s colonial whose multi-flue chimney had been retrofitted from oil to gas. The owner complained of smoke spillage. Our tech found mismatched clay-tile liners and a cracked crown - both accelerated by freeze-thaw cycles on the Palisades ridge. We installed a downdraft-resistant cap and lined the flue with DuraFlex, eliminating the backdraft and restoring safe operation.

FAQs - Fireplace Services in Demarest
The eastern escarpment of the Palisades trap-rock ridge creates a wind-shadow effect that flat-lot Bergen County towns like Closter or Norwood simply do not experience. Chimneys in Demarest must be sized and capped with downdraft-resistant designs that account for this elevation. Standard caps often worsen the problem. If you’re getting smoke spillage on windy days, the ridge is likely the cause. Call (855) 950-3861 for a draft-performance inspection - estimates are free.
Yes. Demarest’s housing stock is dominated by post-WWII homes with chimneys first built for oil boilers, later adapted for gas or wood. That conversion sequence frequently left mismatched clay-tile liner diameters that crack under thermal stress and trap creosote. A Level-2 camera inspection reveals the actual condition. If tiles are damaged or undersized, we install a DuraFlex stainless steel liner sized to your appliance. Call (855) 950-3861 to schedule - the $89 Seasonal Tune-Up includes a visual assessment, or we can perform the full camera inspection if you suspect liner damage.
Annual cleaning is the minimum for Demarest homes, even with light fireplace use. The mature oak and tulip poplar canopy drops debris year-round, and squirrels exploit cracked crowns to nest in flues. Homeowners who say they “barely use the fireplace” are often surprised by what we find. Schedule before each heating season. Call (855) 950-3861 - we’ll put you on the calendar and remind you next year.
Crown cracking and mortar joint deterioration from freeze-thaw exposure. Demarest’s elevated, shallow-soil lots allow frost to penetrate chimney masonry faster than in protected valley locations. A routine cleaning frequently reveals crown damage that needs addressing before winter. Catching it early avoids water infiltration, liner damage, and costlier rebuilds. We document everything with photos and a plain-English verdict. Call (855) 950-3861 for a pre-season inspection.
Yes. We clean, inspect, and repair wood-burning systems; tune, diagnose, and convert gas fireplaces; and install inserts with proper relining for either fuel type. Our trucks carry parts for both. Same-day service is often available. Call (855) 950-3861 - a live person answers.
