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.

Chimney cap and crown work in Mansfield, NJ typically runs $280-$1,850 depending on whether you need a standard cap installation, a custom multi-flue cover for an old farmhouse chimney, or full crown rebuild with coating. Most jobs are completed in a single visit after a Level 2 camera inspection. Call (856) 519-0832 to book a free estimate.
We’ve been driving the rural county roads of Mansfield for over four decades, and we know the chimneys here. They’re different from the post-war ranch stacks in Mount Holly or the subdivision zero-clearance units in West Windsor. Mansfield’s pre-1920 farmhouses with their wide-throat brick chimneys and shared flue arrangements demand a sweep who looks before quoting. Our dispatch is coordinated from our New York City office, but our crews live and work in Burlington County. That means we understand what freeze-thaw cycling does to a tall, exposed masonry crown out on a rural Mansfield parcel, and we don’t recommend a cap or a crown repair until a camera shows you exactly what’s happening inside your flue.
Why Hearthstone Chimney Co. Is Mansfield’s Preferred Chimney Cap & Crown Company
Our reputation in Mansfield was built one farmhouse at a time. Homeowners here talk to their neighbors. They remember which contractor showed up on time, explained the problem plainly, and left the property clean. We’ve earned that trust by documenting every inspection with photos and a plain-English verdict, then backing the work with our 90-Day Done Right Promise in writing.
Response time to Mansfield is typically next-day or within 48 hours during the spring and summer shoulder seasons, when we handle most cap and crown work. Fall and winter bookings fill faster, which is why we recommend post-winter crown inspections once Burlington County’s freeze-thaw cycle subsides.
What separates us from chains and one-truck operators is accountability. We’re not gone next season. With over 42 years serving local communities and a live person answering the phone 24 hours a day, 7 days a week, we plan to be answering calls in Mansfield thirty years from now. That changes how we treat every job.
Our Chimney Cap & Crown Services in Mansfield
Cap Installation
New cap installation on Mansfield’s older farmhouses starts with understanding what your flue actually carries. A standard single-flue cap from a big-box store might fit the opening, but it won’t address the draft problems or creosote conditions beneath it. We size caps after camera inspection, using professional-grade materials from Famco and Copperfield. On newer Mansfield homes with factory-built fireplaces, we stock direct-fit caps that match the manufacturer’s specs. Either way, the number on the estimate is the number on the invoice.
Cap Replacement
Rusted, wind-damaged, or improperly sized caps are common on rural Mansfield properties where the original installer never accounted for multiple appliance connections. We remove the old unit, inspect the flue opening for spalling or liner deterioration, and fit a replacement that seals properly against driving rain and animal intrusion. For farmhouses with deteriorating clay tile, we won’t install a new cap over a flue that’s actively crumbling. The camera shows you why, and you decide the next step.
Crown Repair
Burlington County’s freeze-thaw winters destroy chimney crowns. Water seeps into hairline cracks, expands when temperatures drop below 32°F, and blows the concrete apart by March. On Mansfield’s tall, exposed masonry chimneys, this happens faster because there’s no neighboring structure to break the wind or moderate temperature swings. Our crown repair removes loose material, reforms the slope for proper drainage, and finishes with a waterproof coating. Most crown repairs in Mansfield run $450-$890 and are completed in one day.
Crown Coating
When the crown is structurally sound but weathered, a professional crown coating with HeatShield or similar professional-grade material adds years of protection at roughly half the cost of rebuild. We apply this on Mansfield chimneys after verifying the crown has no active spalling or structural cracks. It’s a preventive measure, not a cover-up. We show you the crown condition on camera before recommending coating versus repair.
Multi-Flue Cap
This is where Mansfield’s farmhouse chimneys demand real expertise. A multi-flue cap covers two or more flue openings with a single hooded structure, preventing rain and debris from entering while maintaining proper draft separation. On older Mansfield properties where one brick flue may carry three appliance connections, a multi-flue cap is often the only way to protect the chimney without making draft problems worse. We fabricate and install custom multi-flue caps from Copperfield and Famco, measured to your chimney’s exact dimensions after full camera evaluation.
Custom Cap
Oversized or irregular flue arrangements on historic Mansfield chimneys sometimes require custom fabrication. We measure, spec, and install custom caps that account for unusual flue spacing, extended chimney height, or architectural requirements. Lead time is typically 7-10 business days, with installation scheduled once the cap is ready.

Common Chimney Cap & Crown Problems We See in Mansfield Homes
- Crown spalling from freeze-thaw cycling. Burlington County winters repeatedly cross the freezing mark, forcing moisture in crown concrete to expand and contract. By early spring, the crown surface is flaking and the mortar beneath is exposed. We catch this with post-winter inspections and repair before water reaches the brick below.
- Single flue carrying three appliances. On rural Mansfield farm properties, we regularly find one brick flue shared by a wood stove insert, furnace exhaust, and open fireplace. This predates modern code and creates dangerous back-drafting conditions. A cap alone won’t fix it. We run a camera first, show you the configuration, and recommend proper separation before any cap installation.
- Caps installed over unlined or deteriorating flues. A previous contractor slapped a cap on and called it protection, but the clay tile beneath is spalling or the flue is unlined entirely. Water trapped by the cap accelerates deterioration. Our inspection finds this before you spend money on the wrong solution.
- Improperly sloped crowns pooling water. Original crowns on pre-1920 Mansfield chimneys were often poured flat or with inadequate overhang. Rain sits, freezes, and erodes the crown from the center out. We re-pitch or rebuild with proper drainage slope as part of crown repair.

FAQs - Chimney Cap & Crown in Mansfield
No. We won’t install a cap over a single flue carrying a wood stove insert, furnace exhaust, and open fireplace without first separating those connections or documenting why separation isn’t immediately feasible. That three-appliance arrangement, common on rural Mansfield parcels, creates back-drafting and third-degree creosote hazards that a cap would only trap. We run a camera, show you the feed, and explain your options. Call (856) 519-0832 for a free evaluation.
Burlington County’s repeated freeze-thaw cycles - temperatures crossing 32°F dozens of times each winter - force water inside crown concrete to expand and contract until the surface spalls. Mansfield’s tall, exposed rural chimneys suffer worse because they catch full wind and temperature swing with no shielding from neighboring structures. Our crown repair addresses this with proper slope, professional-grade materials, and waterproof coating designed for mid-Atlantic conditions.
A multi-flue cap covers multiple flue openings with a single hooded structure, keeping rain and animals out while maintaining draft separation between flues. On Mansfield farmhouses with two or three flues in one chimney stack, it’s often the only cap solution that protects without restricting airflow. We measure and custom-fit after camera inspection to ensure proper clearance and function.
Usually yes, and we’ll prove why on camera. An unlined or crumbling clay-tile flue in a Mansfield farmhouse chimney allows heat, sparks, and combustion gases to reach the brick and mortar directly. Capping it traps moisture and accelerates deterioration. Our inspection shows you the liner condition. If it’s compromised, we explain liner options before any cap installation proceeds. Nothing is hidden.
Because we show you the problem before we quote the fix. Every estimate includes a Level 2 camera inspection with photos you can see and a plain-English verdict. On a farmhouse off a rural county road in Mansfield, our tech found one brick flue carrying a wood stove insert, the furnace exhaust, and an open fireplace all at once - third-degree creosote glazed onto clay tile that had already begun spalling, with the crown cracked from a winter of freeze-thaw. Before quoting anything, we ran a camera down the flue and let the homeowner watch the feed, then fitted a custom multi-flue copper cap over the three flues and coated the crown. Nothing was recommended that the camera hadn’t already shown them. That’s our standard on every Mansfield job. Call (856) 519-0832.
