We’ve been driving the wooded backroads of Montville for over 42 years - from the colonials along Changebridge Road to the split-levels tucked behind the Towaco station. Our dispatch office coordinates crews from New York City, but our trucks roll into Montville’s half-acre neighborhoods with parts already on board: Gelco and Olympia Chimney caps in standard sizes, Copperfield custom-fabricated multi-flue covers, and HeatShield crown coating material mixed for cold-weather curing. When a Montville homeowner calls, a live person answers the phone - not a queue, not an app - and we schedule an inspection that ends with photos you can see and a plain-English verdict.

Why Hearthstone Chimney Co. Is Montville’s Preferred Chimney Cap & Crown Company

Our reputation in Montville was built one three-flue colonial at a time. Homeowners here don’t want a sales pitch; they want someone who recognizes that their 1987 Tudor with a wood-burning fireplace, a 1990s gas insert, and a furnace flue needs a cap-and-crown strategy, not a one-size-fits-all cover dropped on the top flue and a handshake.

Reviews from Montville customers consistently mention the same things: our techs arrive in uniform, lay down floor protection without being asked, and explain why a crown is spalling before quoting the repair. No surprises on the bill - the estimate number matches the invoice number. The 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing.

Response time to Montville is typically within a few days for non-urgent cap and crown work, faster when freeze-thaw damage has opened a leak path into the attic. We know which Montville neighborhoods sit in the coldest pockets of the Morris County Highlands fringe, where crown cracks from hard freeze cycles show up first. That local knowledge means we don’t waste your time with guesses.

Our Chimney Cap & Crown Services in Montville

Cap Installation

New cap installation in Montville is rarely a single-flue proposition. The township’s 1970s-1990s build era favored multi-fireplace floor plans - a formal living room fireplace, a family room gas insert, sometimes a basement wood stove - all venting through one masonry stack. Our Chimney Cap & Crown team measures every flue, checks draft requirements for each appliance, and installs caps that fit the assembly, not just the biggest opening. We stock Gelco and Olympia Chimney stainless caps for standard configurations and order custom-fabricated copper or black steel when the flue spacing demands it.

Cap Replacement

Montville caps take a beating. The dense oak and maple canopy drops debris that packs mesh screens and bends flanges. Squirrels and raccoons force entry at weak points. We remove the failed cap, inspect the flue rim and crown condition beneath it, and install a replacement that accounts for what we find. If the crown is spalled, we quote the repair before the cap goes back on - no cap replacement masking a water intrusion problem that will cost more next spring.

Crown Repair

Crown repair is where Montville’s climate hits hardest. Winter temperatures below 20°F drive moisture into hairline cracks, freeze it, and wedge the concrete apart. By year three or four, the crown is shedding chunks and funneling water into the smoke chamber. We grind out deteriorated material, form a proper slope and drip edge, and pour a new cementitious crown or apply a bonded coating system depending on damage depth. Crown work in Montville is often the difference between a $400 repair and a $4,000 rebuild five years later.

Crown Coating

For crowns with surface cracking but sound structural integrity, we apply professional-grade flexible coating - HeatShield or equivalent - that bridges hairlines and sheds water without the cost of full removal and repour. This is a popular option for Montville homeowners whose crowns are showing early wear but haven’t yet failed. The coating is rated for freeze-thaw cycling and carries the same 90-Day Done Right Promise as our rebuilds.

Multi-Flue Cap

The multi-flue cap is our most common Montville installation. A single cover shelters two or three flues with one integrated mesh skirt and rain diverter, eliminating the gaps between individual caps where water and debris collect. We size multi-flue caps to the full crown footprint, not just the flue centers, and anchor them with stainless straps or masonry screws depending on crown condition. On a wooded cul-de-sac off Changebridge Road, our tech opened a 1988 colonial’s three-flue masonry stack to find a 1990s gas insert vented straight into the original oversized clay tile wood flue with no stainless liner, plus a spalled crown and a branch-loaded cap. We installed a custom multi-flue copper cap sized to the three-flue crown, rebuilt the crown with a bonded coating, and flagged the unlined gas flue for a HeatShield reline before the next heating season.

Custom Cap

When standard caps don’t fit - irregular flue spacing, oversized decorative chimneys, or heritage masonry that the homeowner wants to preserve - we fabricate custom caps from copper, black steel, or stainless. Custom work costs more and takes longer to deliver, but for Montville’s architectural chimneys on premium properties, it’s the only approach that protects without diminishing the roofline.

Trusted Brands We Service in Montville

We don’t substitute builder-grade hardware for professional materials. Our trucks carry Gelco and Olympia Chimney stainless caps in the sizes most common to Montville’s flue dimensions, Famco venting components for gas-appliance retrofits, and Copperfield custom fabrication for multi-flue and specialty covers. HeatShield crown coating and liner products are on every truck. Because we stock for Montville’s housing stock specifically - 8×8, 8×12, and 13×13 clay flue tiles, plus 6-inch and 8-inch stainless liner terminations - most cap and crown jobs don’t wait on parts. If your chimney needs something we don’t have, we order it and return, but that delay is rare.

Common Chimney Cap & Crown Problems We See in Montville Homes

• Freeze-thaw crown spalling. Montville’s position in the Morris County Highlands fringe means harder, longer freezes than lower-elevation towns. Water enters crown cracks in January, expands, and exits as crumbled concrete in March. We see this on every street from the Towaco section to the Pine Brook border.
• Gas-insert venting into unlined wood flues. The 1990s retrofit boom left Montville with dozens of gas inserts blowing acidic condensation into oversized clay tile flues never designed for it. The cap size and draft rating for a wood fireplace are wrong for a gas appliance, and the mismatch accelerates liner deterioration while the homeowner burns unaware.
• Canopy debris loading. Mature oaks and maples overhang Montville rooflines at heights that would get a tree trimmed in newer subdivisions. Each fall, caps fill with leaves, twigs, and helicopter seeds. Blocked mesh screens trap moisture against the flue rim and invite squirrels to nest above the damper.
• Shared-crown water intrusion on multi-flue stacks. Two or three flues share one concrete crown in Montville’s typical colonial plan. When the crown cracks between flues, water enters the chase wall and runs down to the attic framing or fireplace surround. Replacing caps without repairing the shared crown leaves the leak path open.
