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.

Why Hearthstone Chimney Co. Is Mansfield’s Preferred Fireplace Services Company
We’ve been answering the phone with a live person for over 42 years, and that hasn’t changed. Mansfield homeowners know us because we show up when we say we will, document every finding with photos, and explain what we’re seeing in plain English before any Chimney Repair in Mansfield moves forward.
Our reputation here is built on older chimneys - the kind that need patience, not a sales pitch. The 90-Day Done Right Promise backs every job in writing: if it’s not right, we come back, no arguing, no paperwork to dig up. Background-checked, uniformed technicians handle most calls in one visit, and the price we quote is the price on the invoice.
Dispatch and scheduling for Mansfield are coordinated from our New York City office, but the crews serving you are local to Warren County and know the township’s mix of historic farmhouses and suburban development. That matters when you’re deciding whether a clay-tile flue from 1880 can handle another season, or whether a wood-stove retrofit vented into an old fireplace stack is actually safe.
Our Fireplace Services in Mansfield
Gas Fireplace Service
Gas fireplaces in Mansfield’s newer subdivisions and retrofitted farmhouses need annual inspection of the burner assembly, pilot system, and venting. We check for failed thermocouples, deteriorated ember beds, and blocked termination caps - common issues after heavy snow seasons in the Kittatinny Ridge shadow. Our technicians carry replacement parts from Famco and Gelco to restore proper draft and flame pattern in one visit.
Wood Burning Fireplace
This is where Mansfield’s local conditions demand real expertise. Because rural properties throughout the township burn cord wood off their own land - often green or unseasoned - Stage 2-3 glazed creosote builds inside flues here far faster than on the run of suburban chimneys our crew sees in Hackettstown or Phillipsburg. A fireplace “service” that skips a camera pass can miss a tar glaze a brush will not touch. We run a full Mansfield Chimney Cleaning & Sweep with Level 2 inspection and camera on every wood-burning call, show you the images, and explain what we’re seeing before recommending any additional work.
Fireplace Insert
Inserts are popular in Mansfield’s older farmhouses where the original fireplace is too inefficient to heat the space. We measure the existing firebox, verify the flue sizing against the insert manufacturer’s requirements, and handle the full installation including the connector pipe and surround. If the existing flue is unlined or undersized - common in 18th- and 19th-century chimneys - we’ll show you the camera evidence and discuss Mansfield Chimney Liner & Rebuild options using Olympia Chimney or DuraFlex components, never a hard sell.
Damper Repair
A stuck or rusted damper wastes heat and can let smoke back into the room. In Mansfield’s climate, freeze-thaw cycling accelerates damper frame corrosion and mortar deterioration around the throat. We repair or replace cast-iron and top-sealing dampers, and we’ll check the smoke chamber and firebox walls while we’re at it - damage in these areas often travels together in older chimneys.
Trusted Brands We Service in Mansfield
We work exclusively with professional-grade materials: DuraFlex stainless liners, HeatShield cerfractory resurfacing, Gelco chimney caps and dampers, Olympia Chimney relining systems, Famco venting components, and Copperfield repair products. Our trucks carry common parts for Mansfield-area brands, which means most repairs finish in the same appointment. No builder-grade substitutes, no waiting on special orders for standard components.
Common Fireplace Services Problems We See in Mansfield Homes
- Glazed creosote from green cord wood. Rural Mansfield properties burning wood harvested on-site often feed unseasoned logs into the fire. The moisture drives incomplete combustion, coating flue tiles with a hard, shiny tar that standard brushes won’t remove. A camera inspection is the only way to spot it, and mechanical removal is the only safe fix.
- Freeze-thaw spalling on masonry crowns and fireboxes. Warren County’s inland elevation and proximity to the Kittatinny Ridge produce sharper freeze-thaw swings than most of New Jersey. Water enters hairline cracks, expands, and pops off surface layers of brick and mortar. Annual inspection catches this before the crown fails completely.
- Wood-stove retrofits into unlined or undersized flues. Original farmhouse chimneys were built for open-hearth fireplaces, not modern solid-fuel appliances. A stove vented into an unlined stack runs hotter and deposits creosote faster, while the smaller flue may not draft properly. We measure everything and show you the numbers.
- Deteriorated mortar joints in multi-flue chimneys. Mansfield’s 18th- and 19th-century farmhouses often share a single chimney structure between fireplace and stove flues. When mortar erodes, flue gases can cross-leak into adjacent channels. Camera inspection and a smoke test reveal what’s actually happening inside the stack.

FAQs - Fireplace Services in Mansfield
Yes - in Mansfield’s climate, even occasional burning with green or unseasoned cord wood can produce enough glazed creosote to create a fire hazard within a single season. The extended burn season and colder temperatures here mean chimneys accumulate more residue per fire than in milder parts of New Jersey. Call (856) 388-5580 to schedule - estimates are free.
You’re likely dealing with Stage 2-3 glazed creosote, the hard, shiny buildup that forms when unseasoned wood burns at lower temperatures. Standard wire brushes won’t touch it. We encounter this pattern constantly on Mansfield’s rural properties, and we remove it with mechanical tools after documenting the extent with camera inspection. Call (856) 388-5580 for an exact quote - estimates are free.
No. We do not recommend liners, HeatShield relines, or any major repair without showing you camera images of cracked flue tiles, deteriorated mortar joints, or other damage we can point to. Off Rockport Road in Mansfield Township, we serviced a 19th-century farmhouse masonry fireplace whose clay-tile flue had a spalled crown and a wood-stove retrofit vented into an unlined, undersized stack that had never been designed for a solid-fuel appliance. We ran a Level 2 inspection with camera and showed the homeowner third-degree glazed creosote above the smoke chamber, then relined the flue with an Olympia Chimney liner and repaired the firebox and damper so the fireplace could be safely used again. The photos came first. The recommendation came second.
Yes, and these systems need more careful inspection than a standard fireplace. We check that the flue is properly sized for the stove’s output, that the connection pipe is secure and listed for the application, and that the chimney structure can handle the higher temperatures. Many Mansfield farmhouses have retrofits that were done decades ago without proper engineering. We’ll measure, photograph, and explain what you have. Call (856) 388-5580 to book - estimates are free.
We handle gas fireplace service and repair, wood-burning fireplace inspection and cleaning, fireplace insert measurement and installation, damper repair and replacement, firebox repair, and fireplace conversion between fuel types. Most jobs are completed in a single visit by a background-checked, uniformed technician. Call (856) 388-5580 to discuss your specific setup - estimates are free.
