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.
Fast, Reliable Fireplace Services Across Montville
Fireplace service in Montville typically runs $180-$450 depending on whether you need cleaning, repair, or conversion work, and most appointments are completed in a single visit with our crew. If your home has multiple fireplaces - common on the wooded half-acre lots off Changebridge Road, Hook Mountain Road, and the Towaco section - you’ll want each flue inspected annually, especially if any were retrofitted with gas inserts during the 1990s.
We’ve been dispatching to Montville from our New York City office for decades, and our technicians know the township’s housing stock intimately. The 1970s-through-1990s colonials, split-levels, and Tudors that define this Morris County suburb weren’t built with today’s combustion appliances in mind.

Why Hearthstone Chimney Co. Is Montville’s Preferred Fireplace Services Company
Montville homeowners tend to stay put. They’ve raised families in these houses, they know every creak in the floorboards, and they’ve learned to be wary of contractors who talk fast and disappear faster. We don’t do fast talk. We’ve served communities like this for over 42 years, and we plan to be answering the phone for thirty more.
Our reputation here rests on documentation. Every Level 2 inspection ends with photos you can see yourself and a plain-English verdict - no jargon, no scare tactics. If your clay tile liner is cracked, we’ll show you the crack. If your gas insert is venting into an oversized masonry flue without a proper liner, we’ll explain exactly why that matters and what it costs to fix. Then we put our 90-Day Done Right Promise in writing: if it’s not right, we come back, no arguing, no paperwork chase.
Our technicians are background-checked and uniformed, and most jobs are completed in a single visit. The price we quote is the price on the invoice. We’ve learned that Montville customers - particularly the longtime homeowners who make up this community - don’t want surprises. They want the thing done correctly.
Our Fireplace Services in Montville
Gas Fireplace Service
Gas fireplaces in Montville demand a specific kind of attention because so many were installed during the 1980s and 1990s by homeowners upgrading from wood - often without proper relining. The gas insert vents into a flue designed for wood smoke, which moves hotter and faster. Gas exhaust is cooler and wetter. In an oversized masonry flue, it condenses on the clay tile, slowly degrading the surface and seeping into mortar joints. We see this pattern constantly in the colonials near the Pine Brook border and along the wooded stretches of Whitehall Road. Our gas service includes combustion analysis, burner inspection, and a full flue evaluation to catch what a simple “it lights fine” check never would.

Wood Burning Fireplace
Montville’s mature oak and maple canopy is beautiful until it’s dropping debris straight into your flue. Homes on larger lots with trees overhanging the roof - typical in the Towaco and Lower Montville sections - need cap and crown inspection every fall before burning season. We also find significant spalling and freeze-thaw damage in the original masonry of these 30-to-50-year-old chimneys. Winter temperatures here regularly drop below 20°F, and the Morris County Highlands fringe sees harder cycling than lower-elevation towns. Our wood fireplace service includes creosote removal, firebox mortar repair with HeatShield refractory materials, and damper restoration so you’re not sending heat up the flue when the fire’s out.

Fireplace Insert
Insert work is where Montville’s housing history creates the most hidden problems. The township’s build era coincided with the gas insert boom, and many were installed by HVAC contractors or fireplace shops that never pulled permits or ran proper liner sizing calculations. On a wooded cul-de-sac off Changebridge Road, our tech opened a 1988 colonial with two fireplaces and found the upstairs gas insert vented directly into the original oversized masonry flue - no stainless liner, heavy condensation staining on the clay tile, and a nesting blockage at the cap. We installed a correctly sized DuraFlex liner matched to the gas appliance, repaired the spalling firebox joints, and reset the damper, then scheduled the second flue for its own Level 2 inspection. That’s standard practice for us: one flue at a time, fully documented.

Damper Repair and Firebox Restoration
A stuck or rusted damper turns your fireplace into an open window. In Montville’s older homes, we find original throat dampers frozen solid from decades of corrosion, or warped from over-firing when homeowners tried to compensate for a weak draft. We repair or replace with precision-fit components, and if the firebox itself has cracked refractory panels or spalling brick, we restore with professional-grade materials - never builder-grade substitutes - so the assembly is safe for its rated temperature.

Fireplace Conversion
Converting a Montville wood fireplace to gas requires more than dropping in an insert. The flue must be sized to the appliance’s BTU output and fuel type. Natural gas and propane have different venting requirements. The existing clay tile liner, if it’s the original from a 1980s construction, is almost certainly oversized for a gas insert and may be cracked from freeze-thaw exposure. We handle the full scope: gas line coordination, liner installation with DuraFlex or Copperfield components, burner assembly, and final combustion testing. No step gets skipped. The permit application and inspection coordination are part of our service.

Trusted Brands We Service in Montville
We don’t use whatever’s cheapest at the supply house. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - the brands that other sweeps call when they need something that actually fits and lasts. For Montville customers, this means faster turnaround because we’re not ordering parts; we stock the common liner diameters, refractory mixes, and cap sizes these homes need. A DuraFlex gas liner in the correct 4-inch or 5-inch diameter, a HeatShield cerfractory flue spray for resurfacing cracked clay tile, a Gelco stainless cap with proper animal screening - these are on our shelves, not on a two-week backorder.
Common Fireplace Problems We See in Montville Homes
- Gas-insert retrofits vented into oversized masonry flues without stainless liners. The 1990s installation boom left Montville with dozens of these per neighborhood. Condensation stains the clay tile, mortar joints soften, and carbon monoxide risk increases silently. Annual inspection catches it before the damage requires full rebuild.
- Freeze-thaw cracking in original clay tile liners. Montville’s position in the Highlands fringe means harder winter temperature swings than towns closer to sea level. Water penetrates hairline cracks, expands when it freezes, and widens the gap year after year. By the time you notice draft problems, the liner may be in pieces.
- Leaf and debris blockages from overhanging canopy. Those mature oaks and maples that make Montville desirable also drop material straight into uncapped or poorly screened flues. We remove squirrel nests, leaf packs, and broken branches every October - always with a camera so the homeowner sees exactly what was obstructing the flue.
- Multiple flues with staggered maintenance histories. A colonial on a half-acre lot may have a basement wood stove, a main-floor fireplace, and an upstairs gas insert - three separate flues, often with three separate last-service dates. We consolidate these into a single annual schedule so nothing gets forgotten.

FAQs - Fireplace Services in Montville
Each fireplace or insert with its own flue needs separate inspection. In a typical Montville colonial with a basement wood stove, main-floor masonry fireplace, and upstairs gas insert, that’s three flues - often with different liner conditions, different last-service dates, and different failure modes. We bundle these into a single annual appointment with a multi-flue discount. Call (973) 604-2986 to schedule - estimates are free.

Because lighting is not the same as venting safely. Montville’s 1990s gas-insert retrofits were frequently vented into original oversized masonry flues without stainless liners, a code-deficient condition that causes sustained condensation and accelerated clay tile deterioration. The insert lights fine while quietly degrading the flue and creating carbon monoxide risk. Our Level 2 camera inspection reveals what a surface check cannot. Call (973) 604-2986 - we’ll show you exactly what we’re seeing.

Montville’s position in the Morris County Highlands means winter temperatures regularly drop below 20°F, and the repeated freeze-thaw cycling forces water inside mortar joints and clay tile cracks to expand and contract. This spalls brick faces, opens mortar gaps, and shatters liner segments - damage that accelerates each season until repaired. Annual inspection catches early-stage cracking before it requires full rebuild. Call (973) 604-2986 to schedule before the next hard freeze.

Yes, though the service differs. Gas inserts need combustion analysis, burner inspection, and flue evaluation for condensation damage and liner compatibility - especially critical given Montville’s pattern of 1990s retrofits into unlined masonry flues. Wood fireplaces need creosote removal and masonry inspection for freeze-thaw damage. Both need annual attention, just different attention. Call (973) 604-2986 and we’ll schedule the right service for each appliance.

A proper conversion starts with flue sizing: the existing clay tile liner is almost certainly oversized for gas combustion and may be cracked from decades of freeze-thaw exposure. We remove or bypass the damaged liner, install a correctly sized stainless liner matched to the new appliance’s BTU and fuel type, coordinate gas line connection, and perform final combustion testing. The process typically takes one to two days, and we handle permit coordination. Most conversions in Montville run $3,500-$6,800 depending on flue height and access.
