Fanwood isn’t like other towns. Nearly every home here was built between the 1920s and 1950s as a CNJ rail commuter suburb, and that means nearly every chimney is the same vintage, with the same problems developing at the same time. Original terra cotta flue liners. Soft brick mortar. Parged crowns that weren’t designed to survive forty years of Union County freeze-thaw cycles, let alone ninety. When your chimney needs work, you want someone who has seen this exact setup a hundred times before - and who knows whether you’re looking at a targeted repair or a situation where rebuilding makes more sense.
We’re Hearthstone Chimney Co., and we’ve been serving communities like Fanwood for over 42 years. Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like DuraFlex, HeatShield, and Gelco. Most repairs finish in one visit. The price we quote is the price you pay.

Our Chimney Repair Services in Fanwood
Mortar Repointing
Fanwood’s freeze-thaw cycle is brutal on the soft lime-based mortar used in 1920s-1950s construction. Water gets in, freezes, expands, and grinds the mortar joints to powder. We grind out the deteriorated material to proper depth and repoint with color-matched, professional-grade mortar that moves with the masonry instead of fighting it. On a typical Fanwood Colonial Revival, expect this work to run $350-$1,200 depending on how many courses need attention and whether the crown also needs parging.
Spalling Brick Repair
Spalling - the face of the brick popping off from freeze-thaw damage - is epidemic on Fanwood’s older chimneys. Once the hard outer face is gone, the soft inner core absorbs water even faster. We remove spalled units, source matching replacement brick where possible, and address the moisture source. In Fanwood, that source is almost always a cracked crown, failed flashing, or an abandoned boiler flue that’s been dumping condensate into the structure for years. Brick replacement with associated waterproofing typically runs $800-$2,500.
Chimney Waterproofing
Water is what kills Fanwood chimneys. Union County’s repeated winter crossings of the 32°F line mean water enters, freezes, and wedges things apart dozens of times per season. We apply vapor-permeable waterproofing agents that let the masonry breathe while shedding liquid water. This isn’t the hardware-store stuff that traps moisture inside. We use professional-grade formulations from Copperfield and Olympia Chimney, applied after any needed repointing or brick replacement. A full waterproofing treatment on a standard Fanwood chimney runs $400-$950.
Flashing Repair
The junction where chimney meets roof is a common failure point on Fanwood’s older homes, especially where decades of thermal cycling have loosened original step flashing or where earlier repairs used caulk instead of proper metalwork. We fabricate and install custom flashing that integrates with your roofing system, sealed with high-temperature compounds. Most Fanwood flashing repairs run $450-$1,100. If the surrounding sheathing has rotted from long-term leakage, we’ll tell you before we start, not after.
Chimney Rebuilding
Sometimes the damage is too widespread for spot repairs. On Fanwood’s 90-year-old chimneys, we’ve rebuilt from the roofline up, salvaging original brick where sound and replacing with matched units where necessary. A partial rebuild typically runs $2,500-$4,500; full rebuilds above the roofline can reach $6,000-$10,000. We always explain exactly why rebuilding is recommended and show you the photos that support that call.
Tuckpointing
For chimneys where the mortar joints are weathered but the brick remains sound, tuckpointing restores structural integrity and appearance without the cost of full repointing. On Fanwood’s decorative Tudor Revival chimneys, this also preserves the architectural detail that makes these homes distinctive. Tuckpointing runs $500-$1,800 depending on accessibility and joint condition.

Trusted Brands We Service in Fanwood
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - the brands that other chimney professionals specify for their own homes. For Fanwood’s aging flue systems, that means DuraFlex stainless liners that flex to fit deteriorating terra cotta without requiring demolition, and HeatShield cerfractory resurfacing for flues that are cracked but structurally sound. Because we stock these parts and don’t have to special-order for every job, most Fanwood repairs finish in a single visit. The right material, installed correctly, with a warranty that means something.
Common Chimney Repair Problems We See in Fanwood Homes
- Abandoned boiler flues never relined after gas conversion. On almost every street in Fanwood, we find a second flue that served an oil-fired boiler converted to gas decades ago. The flue was capped or abandoned, not properly relined for cooler gas exhaust, and now accumulates condensate that accelerates liner collapse and leaks into the main fireplace flue.
- Freeze-thaw spalling on 70+ year old soft brick. Union County’s winter temperature swings repeatedly cross freezing, forcing water in the masonry to expand and contract. Fanwood’s original bricks and mortar weren’t formulated to survive this indefinitely. Spalling starts at the crown and works down.
- Shared-wall leaks in dual-flue systems. Original construction placed two flues close together with a thin separating wall. As terra cotta liners crack and mortar degrades, exhaust and moisture migrate between flues, causing hidden damage that homeowners often mistake for roof leaks.
- Crown failure from original parging. The concrete wash (parging) applied to Fanwood chimney crowns in the 1930s-1950s typically lasts 20-30 years, not 90. Once it cracks, water enters the crown body, freezes, and destroys it from within. By the time you see interior water stains, the crown is often structurally compromised.

FAQs - Chimney Repair in Fanwood
Yes, or it will continue damaging your active flue and chimney structure. That capped flue was originally for an oil or coal boiler, and when your home converted to gas, the exhaust temperature dropped. Cooler gas exhaust produces more condensate, which the old flue wasn’t designed to handle. The condensate soaks into the surrounding masonry, freezes, and accelerates deterioration of the shared wall between your flues. We’ve relined dozens of these in Fanwood, typically with a properly sized DuraFlex liner or by properly terminating and sealing the abandoned flue if it’s no longer needed. Call (855) 950-3861 and we’ll inspect both flues with our camera so you can see the condition yourself - estimates are free.
Almost always, yes. The original crown parging on a 1920s-1950s Fanwood chimney has exceeded its service life by decades. Cracked crown parging is the primary entry point for water that destroys mortar joints and causes spalling brick. Repointing the sides without fixing the crown is like replacing a roof while leaving a hole in it. We parch the crown with proper concrete mix sloped to shed water, then seal it. The additional cost is typically $900-$2,200 depending on crown size and condition, and it prevents the repointing from being undone in three winters.
Replacement is usually the right call, though HeatShield cerfractory resurfacing can repair certain crack patterns if the liner is otherwise structurally sound. Terra cotta liners in Fanwood’s 1930s chimneys are now 90+ years old. They’ve survived thousands of heating cycles and usually show multiple cracks, spalled interior surfaces, or shifting segments. We camera-inspect to determine which path makes sense. A full stainless liner replacement with DuraFlex runs $1,800-$3,500. Resurfacing, where applicable, runs $1,200-$2,000. We’ll show you the camera footage and explain which option fits your situation.
It’s increasingly common as Fanwood’s housing stock ages past the 90-year mark. On a 1932 Tudor Revival on Forest Road, we tore out a crumbling original oil-boiler flue - never relined after gas conversion - that was dumping condensate into the main fireplace flue. We installed a custom DuraFlex liner and rebuilt the crown, saving the homeowner from a full rebuild. But when spalling brick extends below the roofline, or when the chimney has leaned from foundation settlement, partial or full rebuilding becomes necessary. We always pursue the least invasive solution that solves the problem permanently. Call (855) 950-3861 for an inspection and honest assessment.
Control water entry, and control it early. The three critical points are the crown, the flashing, and the mortar joints. Have the crown inspected annually - we include this in our $89 seasonal tune-up. Address mortar deterioration before water can penetrate deeply. And apply vapor-permeable waterproofing after any repointing work, not before. In Fanwood’s climate, a chimney that sheds water properly will outlast one that doesn’t by decades. The cost of prevention is a fraction of rebuilding. Call (855) 950-3861 to schedule a tune-up and inspection - we’ll photograph everything and give you a prioritized plan.
