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 Gloucester’s Preferred Chimney Repair Company
We’ve served communities across South Jersey for over 42 years, and Gloucester’s pre-WWI housing stock is some of the most technically demanding chimney work we do. The city’s dense rows of late-1800s brick homes, built for waterfront and industrial workers, present problems that suburban sweeps rarely encounter: oversized coal flues venting modern gas appliances, settlement-sheared terracotta tiles, and river-moisture deterioration that accelerates freeze-thaw damage.
Our technicians are background-checked, uniformed, and trained to work in tight Gloucester lots where ladders angle against shared walls and neighboring roofs sit close enough to touch. Most repairs are completed in a single visit with no-hassle upfront pricing - the number on the estimate is the number on the invoice.

Our Chimney Repair Services in Gloucester
Chimney Rebuilding
Some Gloucester stacks are too far gone for spot repairs. When a chimney has lost multiple courses of brick to spalling, or when the structure has tilted from foundation settlement, partial or full rebuilding is the only safe option. We rebuild using matching brick and professional-grade materials from Olympia Chimney and Copperfield, and we document the structural failure with camera evidence before recommending demolition. On waterfront blocks, we often see the damage pattern repeat: river-moisture saturation, freeze-thaw spalling, and lime mortar that has turned to powder. We’ll show you exactly where the wall is compromised and where it still has integrity - sometimes only the upper courses need rebuilding, not the entire stack.

Spalling Brick Repair
Spalling - the flaking and popping of brick faces - is epidemic on Gloucester chimneys exposed to Delaware River fog and winter freeze-thaw cycles. The porous century-old brick soaks up moisture, the temperature drops below freezing, and the expanding ice blows the face off the brick. We remove damaged brick, install matching replacements, and apply breathable waterproofing to slow recurrence. This is not cosmetic work. Spalled brick exposes the inner structure to accelerated deterioration, and on shared-wall twins, water weeping across from a neighbor’s damaged roof can attack your stack even if your side looks sound. We check the whole exposure, not just the obvious damage.

Mortar Repointing
The original lime mortar in Gloucester’s row homes was never meant to withstand a century of river-moisture cycling. We grind out deteriorated joints to proper depth and repoint with mortar matched to the original composition - harder Portland mixes trap water and accelerate brick damage, so we specify correctly for pre-WWI masonry. Repointing a typical Gloucester twin-home chimney runs $800-$1,800 depending on access and joint depth. We won’t quote repointing without first confirming the mortar is actually failing and not just surface-stained; camera inspection included.

Chimney Waterproofing
Water is the enemy of every Gloucester chimney, and the river makes it worse. Our waterproofing treatment uses vapor-permeable sealers from Gelco that allow the masonry to breathe while repelling liquid water. This matters on Gloucester’s oldest homes because trapping moisture inside the brick with the wrong sealer causes more damage than no treatment at all. We apply waterproofing after structural repairs are complete, not as a bandage over failing mortar. A typical application on a standard Gloucester row-home stack runs $450-$850.

Flashing Repair
Step flashing and counterflashing around chimney penetrations are common leak points, especially on Gloucester’s low-slope row-home roofs where snow and river-driven rain sit longer than on pitched suburban designs. We repair or replace flashing using professional-grade materials, and we always inspect the surrounding roof deck for hidden moisture damage. Flashing repair typically runs $350-$750 in Gloucester.

Tuckpointing
For chimneys where the mortar is sound but the aesthetic has degraded, tuckpointing restores the clean, uniform joint lines that defined the original craftsmanship. We match the color and profile precisely. This is less common in Gloucester’s working waterfront housing stock than in restored historic districts, but when homeowners want the stack to look as solid as it is, we execute the work with the same precision we bring to structural repointing.

Trusted Brands We Service in Gloucester
We stock and install professional-grade materials from brands that hold up in Gloucester’s demanding conditions: Gelco for waterproofing systems that breathe properly on century-old masonry, Olympia Chimney for liner components sized correctly for modern appliances in oversized flues, and Copperfield for flashing and structural repair materials. We don’t use builder-grade substitutes. Our trucks carry common sizes and repair components, so most Gloucester jobs don’t wait on parts. When a specialty order is needed, we coordinate from our New York City office and schedule completion as soon as materials arrive.
Common Chimney Repair Problems We See in Gloucester Homes
- Draft reversal in oversized coal flues. Modern gas appliances vented into original coal flues cool exhaust too quickly, causing condensation and backdraft. The chimney looks fine from the street. Inside, acidic moisture is eating the mortar. Only a camera inspection reveals it.
- Settlement-sheared terracotta flue tiles. On Gloucester’s oldest waterfront blocks, soft flood-saturated soil shifts foundations subtly over decades, cracking and offsetting original liner tiles. A homeowner can’t see this. A brush-and-vac cleaning never catches it. The first sign is sometimes carbon monoxide in the living space.
- River-moisture spalling on shared-wall exposures. Fog and tidal moisture saturate porous brick, freeze-thaw cycles pop the faces, and water migrating from neighboring rooflines accelerates damage on walls that look protected. We inspect the full exposure, not just your side.
- Century-old lime mortar turned to dust. The original mortar was never meant to last 120 years, and river-moisture infiltration has accelerated its deterioration. Joints that look intact from the ground may be hollow behind the surface. We probe and camera-verify before recommending any repair scope.

FAQs - Chimney Repair in Gloucester
The flue is too large for the appliance, so exhaust cools before it rises, creating condensation and backdraft. In Gloucester’s pre-WWI row homes, this is nearly universal - the original coal flues were built extra-wide for solid-fuel draft, and no modern gas furnace can generate enough heat to maintain upward flow through that volume. The result is acidic moisture condensing on the flue walls, eating mortar from the inside while the chimney looks sound outside. We scope it with a camera, show you the condensation pattern and any tile damage, and size a proper liner - often with HeatShield - rather than leave you with a dangerous mismatch. Call (856) 543-2929 and we’ll inspect it.
Yes, especially in Gloucester. Gas appliances vent year-round, and an oversized or damaged flue doesn’t care whether you’re burning wood. Carbon monoxide and moisture damage happen silently. Our Level-2 camera inspection catches flue tile offsets, draft reversal, and mortar deterioration that no visual check from the street or roofline ever would. The $89 Seasonal Tune-Up includes this inspection, and estimates are always free. Call (856) 543-2929 to schedule.
It can. Gloucester’s twin homes and row houses often have stacks built on or against shared walls, with water migration paths that don’t respect property lines. We’ve found spalling and mortar failure on one side caused by roofline drainage from the adjoining unit. Our inspection includes the full exposure where accessible, and we’ll document whether the damage is isolated or shared. If both stacks need attention, we coordinate with both owners when possible. Call (856) 543-2929 to discuss your specific situation.
Tar-glaze creosote is hardened, baked-on combustion residue that standard brushing won’t remove. It’s common in chimneys that vented wood or coal stoves for decades, especially in Gloucester homes where the oversized flue cooled exhaust too quickly, causing heavy condensation and buildup. Mechanical brushing alone won’t touch it. We evaluate the extent with a camera and remove it using professional-grade methods - sometimes rotary cleaning, sometimes chemical treatment - then assess whether the underlying flue tile is sound. If the tile is cracked from settlement or age, we’ll show you and discuss relining options. Call (856) 543-2929 for an inspection.
No. We won’t recommend any work without camera evidence you can see for yourself, and we’ll tell you plainly when work can safely wait. On a waterfront block off Monmouth Street, our tech scoped a stack shared between two twins and found the original terracotta flue tile offset and cracked from foundation settlement, with a modern gas furnace vented into the oversized coal flue above it. We ran a camera down the stack, showed the homeowner the sheared tiles and the draft reversal on-screen, and HeatShield-relined the flue to properly size it for the appliance instead of selling an unnecessary full rebuild. The mirrored chimney on the adjoining unit needed the same conversation the following week. Done right - and we stand behind it. Call (856) 543-2929 for a free estimate.
