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.

We know Montville’s homes. The township’s wooded half-acre lots off Changebridge Road, Hook Mountain Road, and the cul-de-sacs near the Towaco border are filled with the colonial and traditional-style houses built during Morris County’s 1970s-1990s suburban expansion. Many of these places have two or three masonry fireplaces, original clay tile flue liners now thirty to fifty years old, and gas inserts from the 1980s and 1990s that were never properly relined. That combination means chimney repair here is rarely a single-flue job. Our Chimney Repair team treats each flue as its own system, because in Montville, it usually is.
Dispatch and scheduling for Montville are coordinated from our New York City office, but the crews that arrive at your door live and work in Morris County. They know the difference between a Towaco section ranch and a Montville Heights colonial, and they know what the freeze-thaw cycles in the Morris County Highlands fringe do to mortar joints that have already seen four decades of winters.

Our Chimney Repair Services in Montville
Mortar Repointing
Montville’s freeze-thaw cycles are brutal on mortar. Water seeps into joints during January thaws, expands when temperatures drop below 20°F, and opens gaps that let more water in next cycle. Homes near the wooded ridges off Hook Mountain Road see this accelerated by wind-driven rain. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade mortar formulated for New Jersey’s climate. A typical mortar repointing job on a Montville colonial chimney stack runs $1,200-$2,800.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is common on Montville chimneys where original construction used softer brick or where decades of moisture intrusion have compromised the masonry. The condition is not cosmetic. Once the brick face spalls, the interior structure absorbs water faster, and freeze-thaw damage accelerates. We remove spalled brick, match replacement units, and rebuild the affected courses with proper weep details and crown overhang to shed water. Spalling brick repair in Montville typically costs $900-$2,400 depending on height and accessibility.

Chimney Waterproofing
Montville’s dense oak and maple canopy is beautiful. It also keeps chimney masonry shaded and damp for days after rain, and drops organic matter that holds moisture against brick. We apply vapor-permeable waterproofing agents from professional-grade suppliers that allow the chimney to breathe while repelling liquid water. This is not the hardware-store spray that traps moisture inside. Waterproofing a Montville chimney runs $650-$1,400 and is often paired with repointing or crown repair for lasting protection.

Flashing Repair
The intersection where chimney masonry meets roof is a leak point on every house, and Montville’s older colonials often have original step flashing that has corroded or pulled loose as the house settled. We fabricate and install custom flashing with proper counterflashing reglets, sealed with professional-grade compounds. Flashing repair in Montville typically runs $450-$1,100.

Chimney Rebuilding
When spalling, mortar deterioration, and liner damage have compromised the structural integrity of the stack, partial or full rebuilding is the only sound option. We rebuild with matching brick, proper reinforcement, and crowns sloped to shed water and debris from Montville’s overhanging canopy. Rebuilds range from $3,500-$8,500+ depending on height and design.

Tuckpointing
For Montville homeowners with historic or architecturally detailed masonry, tuckpointing restores both function and appearance. We carefully remove failed mortar and replace it with precisely tooled joints that match the original profile. This is skilled work, and we treat it that way.

Trusted Brands We Service in Montville
We do not use builder-grade substitutes. Our Montville repairs rely on professional-grade materials from Gelco, Olympia Chimney, and Famco - brands that have proven themselves in the field for decades. We stock common components locally, so a cap replacement or damper repair does not turn into a two-week wait for parts. When we install a stainless liner for a gas insert retrofit, we use DuraFlex or HeatShield systems specified to the appliance and flue size, not whatever fits loosely. The right material for the job, installed correctly, backed in writing.
Common Chimney Repair Problems We See in Montville Homes
- Gas inserts vented into original oversized flues. In Montville’s 1980s-2000s retrofits, gas inserts were often installed directly into original wood-burning masonry flues with no stainless liner. The oversized flue never gets hot enough to establish proper draft, condensation forms on clay tiles, and the acidic exhaust eats the liner from inside while creating carbon monoxide risk. We find this pattern constantly in the colonial build-outs off Changebridge Road and the Towaco section.
- Freeze-thaw mortar destruction on exposed stacks. Montville sits on the Morris County Highlands fringe where hard freeze-thaw cycling is annual and severe. Mortar joints on chimneys above the roofline take the worst of it, opening gaps that let water reach the flue and firebox. Repointing before winter is preventive maintenance that avoids rebuild costs.
- Multi-flue properties with one flue neglected. Because so many Montville homes have two or three fireplaces, homeowners often use one regularly, inspect it occasionally, and forget the others. The second or third flue - sometimes serving a basement appliance or a master bedroom gas insert - hides cracked tiles, failed dampers, or animal nesting for years until smoke or CO shows up indoors. Every flue is its own system. Every flue needs its own inspection.
- Canopy debris blocking flue openings. Montville’s mature oaks and maples overhang rooflines across the township. Each fall, leaves, twigs, and helicopter seeds collect in flue openings and on chimney caps. Blocked flues back up smoke and carbon monoxide. Damaged or missing caps let animals nest. A proper cap installation with correct mesh sizing prevents both problems.

We price everything upfront before work begins, and we photograph what we find so you see what we see. Estimates are free. Call (973) 604-2986.

FAQs - Chimney Repair in Montville
Yes. Each flue is a separate venting system with its own liner, damper, and exposure to damage. In Montville’s multi-fireplace colonials, we regularly find that the main living room flue has been maintained while the basement or master bedroom flue has gone uninspected for a decade or more, hiding cracked clay tiles or a failed damper. We inspect and document every flue with photos. Call (973) 604-2986 to schedule - estimates are free.
Almost certainly yes, if it was not installed with one. The 1990s gas insert retrofits we see in Montville were frequently vented directly into original oversized masonry flues with no stainless liner, a condition that violates current codes and creates sustained condensation that destroys clay tile from the inside out. The oversized flue also fails to maintain proper draft, which can push carbon monoxide into living spaces. We verify with a Level-2 camera inspection and install a properly sized DuraFlex stainless liner when needed.
It is repairable, and it is not cosmetic. Spalling brick exposes the interior structure to accelerated water damage, and cracked mortar joints are the entry point for the freeze-thaw cycle that destroys Montville chimneys each winter. Left unaddressed, what starts as surface repair becomes partial or full rebuild territory. We assess the depth of damage, quote repointing or brick replacement as appropriate, and show you photos so you understand exactly what needs doing and what can wait.
Serious enough to address before burning season. Debris in the flue restricts draft, causes smoke backup, and creates a fuel source for chimney fires if ignited by creosote. In Montville’s heavily wooded neighborhoods, we also find that accumulated organic matter attracts moisture that accelerates liner deterioration and provides nesting material for animals. A proper cap with correct mesh sizing stops the debris while maintaining proper venting. We install Gelco and Famco caps specified to your flue dimensions.
A Level 1 inspection is visual, accessible-surface examination - appropriate for annual maintenance on a system with no changes. A Level 2 inspection, which we recommend for most Montville homes given their age and multi-flue complexity, includes video scanning of the flue interior, inspection of accessible portions of the chimney exterior and attic, and documentation with photos you receive. A Level 3 inspection involves demolition of building materials to access concealed areas, and is only ordered when Level 2 evidence suggests hidden hazards. For a 1970s-1990s colonial with gas insert retrofits, Level 2 is the right starting point. Call (973) 604-2986 to book.
Ready to Get Your Montville Chimney Repaired Right?
We were called to a wooded cul-de-sac off Changebridge Road where a 1980s colonial had two masonry fireplaces plus a basement flue, and the upstairs gas insert had been vented straight into the original oversized wood-burning flue with no stainless liner ever installed. Our tech found spalling brick at the crown, a cracked clay tile liner downstream of the insert, and first-degree creosote glazing the smoke chamber - we installed a HeatShield-cast liner repair on the wood flue, fitted a DuraFlex stainless liner for the gas appliance, repointed the crown, and capped both flues before the fall leaf drop. The homeowner had lived there twenty-two years and never known the gas flue was unlined. That is why we photograph everything and explain it plainly.
If you own a Montville home with multiple fireplaces, original clay tile liners, or a gas insert from the 1980s-2000s, the condition of your chimney is probably more complex than a single-flue inspection would reveal. We will show you exactly what you have, what it needs, and what can wait. No pressure. No surprises on the bill. Done right - and we stand behind it.
