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’ve been repairing chimneys in Morris County communities for over 42 years. Dispatch and scheduling are coordinated from our New York City office, but our crews live and work in this area. They know the difference between a chimney in the railroad corridor villages and one in the wooded western hills. That local knowledge matters when you’re diagnosing why a flue isn’t drafting properly or where water is getting in.
Why Hearthstone Chimney Co. Is Long Hill’s Preferred Chimney Repair Company
Long Hill homeowners tend to stay put. The colonials and split-levels built during the 1950s-70s expansion from the village centers still hold families who raised children here and now want the place maintained right. We understand that. Our 90-Day Done Right Promise - in writing, no arguing - means if something isn’t right, we come back. No paperwork shuffle, no runaround.
Our reputation here is built on showing our work. Every Level-2 camera inspection ends with photos you can see and a plain-English verdict. When we find cracked clay tile in an 80-year-old Gillette chimney or third-degree glazed creosote in a Meyersville wood stove flue, we explain what it means, what it costs, and what happens if you wait. The number on the estimate is the number on the invoice. A square deal.
Calls are answered by a live person, 24/7. Most repairs are completed in a single visit because our trucks carry the materials we need. And our standing offers include $50 off any repair over $250, a free second opinion on any written estimate, and a permanent 5% senior and veteran discount.
Our Chimney Repair Services in Long Hill
Chimney Waterproofing
Long Hill’s proximity to the Great Swamp wetland system elevates ambient moisture across the township, especially in Meyersville and the western hamlets. That moisture, combined with freeze-thaw cycles through extended heating seasons, penetrates porous brick and deteriorates mortar joints from the inside out. We apply professional-grade water repellents formulated for masonry chimneys, not generic sealers that trap moisture. Our crews waterproof crowns, wash surfaces, and address the underlying spalling before it reaches the flue. Done right - and we stand behind it.

Flashing Repair
Flashing failures are among the most common calls we receive in Long Hill after severe weather. Wind-driven downdrafts from the Watchung ridgelines lift chimney caps and peel back flashing, creating the ceiling stains that send homeowners into their attics with flashlights. We repair and replace flashing using copper and stainless materials from Copperfield and Famco, integrated properly with your roofing system. In the field vignette our crew still talks about: a Meyersville homeowner called after a nor’easter left a spreading ceiling stain. We found the cap lifted by downdraft, flashing peeled back, water running down the flue into the attic. We reset the cap, repaired the flashing with new copper, and treated third-degree glazed creosote with a rotary cleaner before waterproofing the crown. The smoke test confirmed what the homeowner had noticed - a sluggish draft for weeks.

Chimney Rebuilding
Some Long Hill chimneys, particularly the older masonry stacks in Stirling and Millington’s railroad corridor, have simply reached the end of their service life. Clay tile flues installed 80-100 years ago crack and shift. Crowns crumble. Brick faces spall off in layers. When repair is no longer economical, we rebuild using professional-grade materials from Gelco and Olympia Chimney, matched to your home’s architecture and built to current standards. We document the condition with camera inspection before any work begins, so you see what we see and understand why we’re recommending what we do.

Mortar Repointing & Spalling Brick Repair
The cold-air drainage in Long Hill’s valley setting means overnight temperatures drop lower than in nearby towns. That extra thermal cycling stresses mortar joints, especially on chimneys already softened by Great Swamp moisture. We grind out deteriorated mortar to proper depth and repoint with color-matched, weather-resistant mortar formulated for New Jersey freeze-thaw exposure. For spalled brick faces, we repair or replace as needed, addressing the moisture source so the problem doesn’t repeat next season.

Tuckpointing
For historic chimneys in Long Hill’s older village centers, tuckpointing preserves both function and appearance. We remove failed mortar and replace it with period-appropriate materials and techniques, maintaining the character of homes that have stood for a century or more.

Trusted Brands We Service in Long Hill
We don’t use builder-grade substitutes. Our trucks stock professional-grade materials from Olympia Chimney, Famco, and Copperfield - the brands that other chimney professionals specify for their own homes. For Long Hill customers, that means faster turnaround because we’re not waiting on parts orders, and repairs that hold up to the township’s particular weather stresses. When we rebuild a crown or replace a cap after a Watchung downdraft event, we install components rated for wind exposure that exceeds what standard hardware-store inventory can handle.
Common Chimney Repair Problems We See in Long Hill Homes
- Downdraft-damaged caps and water intrusion. Long Hill’s valley position between the Watchung ridgelines creates wind patterns that routinely displace chimney caps on the leeward side - failures rare in the open towns just east of the ridge. Once the cap is lifted, rain enters the flue, rusts dampers, and stains ceilings.
- Freeze-thaw spalling accelerated by swamp moisture. Proximity to the Great Swamp elevates ambient humidity, especially in Meyersville. Moisture-saturated brick faces spall and mortar joints deteriorate through repeated freeze-thaw cycles, loosening crowns and breaking flashing seals.
- Third-degree glazed creosote in wood stove flues. Techs working the wooded western edges regularly encounter glazed creosote buildup from fires burned low through long, damp shoulder-season nights. A standard brush sweep won’t touch it. Rotary cleaning or chemical treatment is required before the chimney is safe.
- Cracked clay tile in century-old flues. The railroad corridor villages of Stirling, Gillette, and Millington retain meaningful inventory of chimneys with original clay tile flues now 80-100+ years in service. Thermal stress from Long Hill’s extended heating season finishes what age started.

FAQs - Chimney Repair in Long Hill
Wind-induced downdrafts from the Watchung ridgelines are the most common cause in Long Hill, especially on homes on the leeward side of the ridge. A standard sweep removes creosote but doesn’t fix a cap that’s been lifted or a flue that’s fighting negative pressure. We diagnose draft problems with smoke testing and camera inspection, then repair the cap, flashing, or crown issue that’s letting wind push smoke back into your home. Call (908) 589-8342 - estimates are free.
First-degree creosote is flaky and brushes off easily; third-degree is hardened, glazed, and tar-like, requiring rotary cleaning or chemical treatment. In Meyersville and Long Hill’s wooded western areas, we see third-degree buildup regularly from low, smoldering fires burned through damp shoulder-season nights. A standard brush sweep leaves it in place, creating a genuine fire hazard. Our camera inspection identifies the type before we quote the work. Call (908) 589-8342 for an exact quote - estimates are free.
Long Hill runs colder overnight than nearby towns, extending your heating season at both ends and increasing annual flue use. That extra thermal cycling cracks older clay tile and stresses mortar joints, while the longer burn seasons produce heavier creosote accumulation. We recommend inspection frequency matched to actual use, not just a calendar date. Call (908) 589-8342 to schedule - estimates are free.
Yes, almost certainly. The elevated ambient moisture from the Great Swamp system saturates masonry, and Long Hill’s freeze-thaw cycles do the damage. Water enters micro-cracks, expands when frozen, and spalls brick faces while cracking crowns. We repair the crown, replace spalled brick, and apply professional-grade water repellent to break the cycle. Camera inspection shows you the full extent before any work begins. Call (908) 589-8342 - estimates are free.
We do. The downdraft winds that come off the Watchung ridgelines lift and peel flashing at rates we don’t see in the open suburban towns to the east. After every significant nor’easter, our Long Hill flashing repair calls spike. We use copper and stainless materials rated for higher wind exposure, installed with proper integration to your roof system. Call (908) 589-8342 for an inspection - estimates are free.
