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.

AfterTrusted Chimney Repair for Paterson Homeowners
Chimney repair in Paterson typically costs between $350 for minor mortar repointing and $4,500 for partial rebuilding, with most jobs completed in a single visit. Hearthstone Chimney Co. has served Passaic County homeowners for over 42 years, and our background-checked, uniformed technicians arrive with the materials and tools to finish the work the same day we start it.
Paterson’s freeze-thaw cycles are hard on brick and mortar. Water seeps into hairline cracks in autumn, expands when temperatures drop below 20 degrees in January, and turns small problems into spalled brick and crumbling crowns by spring. We’ve repaired chimneys in every neighborhood from Eastside to South Paterson, from the historic districts near the Great Falls to the hillside homes off Route 20. The pattern is always the same: the homeowner noticed something six months ago, hoped it would hold, and now needs more than a quick patch. Russell Haines founded this company in 1984 on the principle that a square deal and honest information beat a fast sell every time. That’s why we document every chimney with a Level-2 camera inspection, show you the photos, and give you a plain-English verdict before any work begins. Call (973) 604-2986 - a live person answers, 24 hours a day.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, matched mortar into the joints. In Paterson, we see accelerated mortar decay in homes built before 1960 with lime-based mortar that has simply reached the end of its lifespan, as well as in chimneys where previous owners used Portland cement repointing that trapped moisture and caused more damage. Our technicians remove the old material to a uniform depth, dampen the joints to prevent premature drying, and pack new mortar in layers using tools matched to the original joint profile. We use HeatShield refractory mortars for firebox areas and traditional lime-based mixes for above-roof work where breathability matters.
Spalling Brick Repair
Spalling brick repair addresses what occurs when water trapped inside brick freezes and expands, flaking off the face of the brick and leaving the inner structure exposed to more moisture. In Paterson’s climate, south-facing chimneys often show the worst spalling because daily freeze-thaw cycles are more frequent where sun hits. We assess whether the damage is surface-level or structural: minor spalling can be addressed with brick replacement and improved waterproofing, while widespread spalling through multiple courses usually indicates a need for partial rebuilding. Our crews carry replacement brick matched for size, color, and absorption rate, and we source from the same regional suppliers used in original Paterson construction when possible.
Chimney Waterproofing
Chimney waterproofing applies a vapor-permeable sealant to the exterior masonry that blocks liquid water while allowing trapped moisture to escape. This is critical in Paterson, where annual precipitation exceeds 47 inches and the hilly terrain around Garrett Mountain and the Watchung ridges drives wind-driven rain against chimney walls. We do not use generic waterproofing products from hardware stores. Hearthstone applies professional-grade treatments from Olympia Chimney and Copperfield, formulated specifically for fired clay brick and set to proper coverage rates per square foot. The treatment lasts 7-10 years with proper application, and we include a written specification of what was applied and when it should be inspected again.
Flashing Repair
Flashing is the sheet metal barrier where your chimney penetrates the roof, and it is the single most common source of chimney-related leaks we find in Paterson homes. Step flashing, counterflashing, and cricket saddles all deteriorate over time; in older Paterson neighborhoods like Sandy Hill, we regularly find original galvanized flashing that has corroded through after 50+ years, or DIY repairs with caulk and roofing cement that trapped water instead of directing it away. Our flashing work uses copper or stainless steel from Famco, fabricated to fit your specific roof pitch and chimney dimension, not bent from stock pieces. We integrate the new flashing with your existing roofing underlayment and provide photos of the completed work from both the roof and attic sides.
Chimney Rebuilding
Partial or full chimney rebuilding becomes necessary when structural integrity is compromised by widespread mortar failure, leaning, or foundation settlement. In Paterson, we’ve rebuilt chimneys in homes from the 1880s mill-worker housing near the Passaic River to mid-century ranches in the Hillcrest section, and each requires a different approach to matching materials and meeting current code. Our rebuilds include proper footings where the original foundation has failed, reinforced flue liners from DuraFlex or Gelco, and crowns poured with proper slope and overhang to shed water. Russell Haines personally reviews every rebuild estimate to confirm the scope is neither excessive nor insufficient.
Tuckpointing
Tuckpointing is the decorative and functional technique of removing damaged mortar and replacing it with fresh material, sometimes with a thin contrasting line for aesthetic effect. In Paterson’s historic districts, particularly around the Great Falls and in portions of the Eastside Park neighborhood, original tuckpointing is part of the architectural character and must be matched precisely for any repair to avoid a patchwork appearance. Our masons are trained in period-appropriate techniques and maintain a library of local mortar samples for color and texture matching. We grind joints to consistent depth, remove all loose material, and finish with tools that replicate the original tooling marks.

Brands We Service for Chimney Repair
We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind ours. For chimney liners and relining systems, we install DuraFlex stainless steel liners and HeatShield cerfractory flue sealants - we’ve completed hundreds of liner installations with these products and stock the full range of diameters and flex configurations for same-day completion. Gelco chimney caps and Famco venting components are our standard for cap, crown, and top-sealing work; we maintain direct supplier relationships that let us source custom sizes without the delays that send other contractors back for a second trip. Olympia Chimney supplies our waterproofing treatments and many of our stainless steel chimney covers, and we specify Copperfield refractory and masonry products for firebox repairs and rebuilds where heat resistance and dimensional stability matter most.
Whether your chimney was originally built with these brands, has been repaired with other materials, or you’re not sure what you’re looking at, we can help. Our Level-2 inspection identifies what is in place now, what condition it’s in, and what professional-grade replacement will last. We do not substitute builder-grade materials to cut costs, and we document what we install so you have a record for future owners or your own maintenance planning.
Signs You Need Chimney Repair Right Now
- White staining (efflorescence) on exterior brick - This powdery white deposit is mineral salts left behind when water moves through masonry and evaporates. It means water is getting in, and in Paterson’s climate, that water will freeze, expand, and begin spalling brick within one or two winters. We’ve seen efflorescence that looked minor lead to $2,000+ in rebuilding costs three years later.
- Cracked or missing mortar joints - Open joints are direct channels for water into the wall structure. In hillside Paterson homes where chimneys are exposed to wind from multiple directions, we’ve measured joint recession of half an inch or more in chimneys that looked fine from the ground. The repair is repointing now, or brick replacement later.
- Rust stains on the chimney exterior or in the firebox - Rust indicates that metal components, usually the damper or a failing liner, are corroding from moisture exposure. A rusted damper can seize open or closed; a rusted liner can fail to contain combustion gases. Both are safety issues that camera inspection can confirm.
- Chimney crown cracks or deterioration - The concrete crown is your chimney’s umbrella. When it cracks, water flows directly into the flue and the interior masonry. In Paterson, we’ve replaced crowns that were poured without proper reinforcement and without adequate slope, pooling water that destroyed the flue below. A proper crown repair or replacement with Gelco or Copperfield materials stops this progression.
- Leaning or separated chimney structure - Any visible lean or gap between chimney and house is a structural emergency. It indicates foundation failure, corroded anchor straps, or long-term water damage to the supporting structure. Do not use the fireplace. Call for inspection immediately; this is not a repair that can wait for convenient timing.
Our Chimney Repair Process - Step by Step
- 1
Schedule your inspection. Call (973) 604-2986 and a live person will answer, any hour of any day. We’ll find a time that works for you, typically within a few business days. There’s no charge for the estimate, and no obligation to proceed.
- 2
Level-2 camera inspection and documentation. Our technician arrives in a marked vehicle, in uniform, and begins with a full interior and exterior examination. We run a high-resolution camera up the flue to document creosote buildup, liner condition, mortar joint integrity, and any obstructions or structural defects. You receive the photos and a plain-English verdict, not a technical report designed to confuse.
- 3
Upfront pricing with options. If repair is needed, we explain what must be done now, what can wait with monitoring, and what is simply good practice. You’ll get a written estimate with a single number for each option, the number that appears on your invoice if you proceed. No surprises on the bill.
- 4
Professional repair with documented materials. Most repairs are completed in a single visit because our technicians arrive with the tools and materials specified in your estimate. We use only the professional-grade brands we name, installed to manufacturer specifications. Russell Haines requires photo documentation of completed work for every job.
- 5
Written warranty and follow-up. Every repair is covered by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. We also note recommended inspection intervals based on what we found, so you can plan ahead instead of reacting to the next problem.
How Much Does Chimney Repair Cost in Paterson?
A typical mortar repointing job on a standard single-flue chimney in Paterson runs $350-$850, depending on how many courses need work and whether scaffold access is required. Spalling brick repair with replacement of damaged units and waterproofing application usually falls between $800 and $2,200. See our guide on how much Chimney Repair costs for full pricing details. Flashing repair or replacement ranges from $450 for localized step flashing work to $1,800 when a full cricket saddle and counterflashing system is needed. Partial chimney rebuilding starts around $2,500 and can reach $4,500 or more for taller structures or complex access situations. Full waterproofing treatments are typically $600-$1,200 based on chimney surface area and whether pre-treatment repairs are needed first.
Several factors move these numbers. Height and roof access matter: a two-story chimney on a steep slate roof in the Eastside Hills takes longer to reach safely than a single-story ranch in South Paterson. The extent of hidden damage revealed only after work begins affects final cost, which is why we photograph everything and discuss contingencies before you approve the work. Material matching for historic homes can add cost if we need to source specific brick from regional suppliers. And the season matters: waterproofing and crown work need dry conditions and moderate temperatures, so scheduling in spring or early fall often produces better results than rush jobs in wet November weather.
To avoid overpaying, get a second opinion on any estimate over $1,000. Hearthstone offers a free second opinion on any written estimate from another contractor - bring us their paperwork and we’ll tell you if the scope and price are reasonable. Never proceed with major chimney work without photo evidence you can see for yourself. And be wary of any contractor who cannot specify the materials they will use by brand and product name.

Frequently Asked Questions - Chimney Repair in Paterson
Chimney repair fixes structural and functional damage to the masonry, metal components, and waterproofing systems of your chimney, while chimney cleaning removes combustible creosote deposits from the flue interior. A clean chimney with cracked mortar or a rusted liner is still unsafe to use, and a structurally sound chimney with heavy creosote buildup is a fire hazard. We perform both services and will tell you honestly which your chimney needs, or whether it needs both. Call (973) 604-2986 for an inspection that sorts this out.
Most chimney repairs we perform in Paterson are completed in a single visit of 3-6 hours. Repointing and flashing work typically fall in this range. More extensive spalling brick repair or partial rebuilding may require a second day if extensive mortar curing is needed between courses. We tell you the expected duration in your written estimate, and we do not leave scaffolding or materials on your property overnight unless weather forces a pause. Our goal is to finish what we start.
Chimney repair in Paterson ranges from approximately $350 for minor mortar repointing to $4,500 or more for partial rebuilding, with most homeowners paying between $800 and $2,500 for typical repairs. The specific price depends on the type of repair, chimney height and access, extent of damage, and whether matching historic materials is required. We provide upfront pricing with no surprises on the bill, and we offer a free second opinion on any written estimate from another contractor. Call (973) 604-2986 for your exact quote - estimates are free.

If it doesn’t, we can retrofit with professional-grade replacements that fit properly and last.
We do not promise same-day dispatch for routine repairs, but we do prioritize genuine emergencies: leaning chimneys, active water infiltration during storms, and structural damage that creates immediate safety hazards. Our phones are staffed by a live person 24 hours a day, 7 days a week, so you can always reach us to describe the situation and get guidance. For non-emergencies, we typically schedule within a few business days, with seasonal variation - call early in autumn before the rush.
Every chimney repair is covered by our 90-Day Done Right Promise, backed in writing with no paperwork and no arguing. If it’s not done right, we come back and make it right. Beyond that period, manufacturer warranties apply to the specific materials we install - DuraFlex liners carry their own warranty terms, HeatShield has its own coverage, and so on. We document what was installed so you have records for any future claim. This is how we’ve operated for over 42 years, and it’s why Russell Haines insists on the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
Clear a path to your fireplace or stove area, remove fragile items from the mantel and hearth, and ensure roof access is possible - unlock gates, secure pets, and let us know if your roof pitch or height requires special equipment. You do not need to clean the fireplace beforehand; we need to see it as you use it. If you have previous inspection reports or estimates, have them ready. We’ll handle the rest, including drop cloths, containment, and cleanup. Call (973) 604-2986 when you’re ready to schedule.
