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 Ewing’s Preferred Chimney Cap & Crown Company
Homeowners in Ewing call us because we understand what we’re looking at. The township’s housing stock - dense with 1950s-1970s brick ranches and Cape Cods - presents chimney configurations that younger techs from outside the market misread. We’ve worked Bear Tavern Road, Parkway Avenue, and the Scotch Road corridors enough to recognize a shared single-stack chase before we set the ladder.
Our reputation here is built on documentation. Every inspection ends with photos you can see and a plain-English verdict. No guessing, no upselling based on what you can’t verify. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we make it right, no paperwork and no arguing.
Calls are answered by a live person 24 hours a day, 7 days a week. Background-checked, uniformed technicians complete most jobs in a single visit, and the price we quote is the price on the invoice.
Our Chimney Cap & Crown Services in Ewing
Cap Installation
New cap installation in Ewing runs $280-$450 for a standard single-flue stainless unit, with multi-flue caps starting around $480. The critical detail on Ewing’s shared-chase chimneys: sizing. We measure each flue opening independently. A cap that fits the old coal-era furnace flue opening but not the gas appliance venting into it masks an unlined flue - a combination that fails NJ Uniform Construction Code and surfaces on home inspection reports in Ewing’s active TCNJ-adjacent market.

Cap Replacement
Replacing a rusted or wind-damaged cap in Ewing typically costs $250-$420. We remove the old unit, inspect the flue tile beneath for spalling or cracking, and fit a replacement from Gelco or Olympia Chimney sized to the actual appliance, not the original opening. In the older neighborhoods near Trenton, we regularly find that the “standard” cap was never standard at all - just the closest size a previous installer had on the truck.

Crown Repair
Crown repair in Ewing ranges from $380 for targeted seam patching to $680 for full rebuilds on deteriorated cast-in-place mortar crowns. The Delaware River valley moisture intensifies Central New Jersey’s freeze-thaw cycle, and Ewing’s 1950s-1970s ranch crowns crack along the flue seam within a decade. We cut out the damaged section, form and pour new crown material with proper overhang and drip edge, and seal the cure. Done right - and we stand behind it.

Crown Coating
For crowns with surface cracking but sound structural integrity, crown coating in Ewing runs $320-$480. We apply a flexible, breathable membrane formulated for masonry chimney crowns, not generic waterproofing. This buys years of protection without the cost of full rebuild. We won’t recommend it if the crown is too far gone. Photos you can see, a plain-English verdict.

Multi-Flue Cap
Multi-flue caps are our most common recommendation for Ewing’s shared-chase chimneys. A properly sized multi-flue cap - typically $520-$750 installed - covers each flue opening independently while sheltering the entire crown. This stops wind-driven rain from entering one flue and migrating down the shared masonry into the adjacent stack. We stock stainless multi-flue units from Famco and Copperfield sized for Ewing’s standard chase dimensions.

Custom Cap
For non-standard chase dimensions or heritage homes near the Trenton border, custom fabricated caps run $680-$950. We measure on-site, specify in galvanized or stainless, and install with proper clearances and screen mesh to keep wildlife out while maintaining draft.

Common Chimney Cap & Crown Problems We See in Ewing Homes
- Wind-driven rain migrates between shared flues. On Ewing’s single-stack brick chases, a failed cap on the fireplace flue lets water enter and travel down the shared masonry into the furnace flue. The homeowner sees damp residue in a flue that “never had a water problem” - and the real fix is addressing both caps and the crown seam between them.
- Freeze-thaw cycle destroys crown edges. Ewing’s position adjacent to the Delaware River valley adds atmospheric moisture that intensifies winter freeze-thaw. Original cast-in-place mortar crowns crack along the flue seam within a decade, spalling the edges and opening a path straight into the smoke chamber.
- Oversized caps mask unlined gas flues. After gas conversions, Ewing’s furnace flues were almost never relined to the smaller diameter gas appliances require. A cap sized for the old coal-era opening sits loosely on the new venting, masking the mismatch until an NJ home inspector flags it during a TCNJ-area sale.
- Wood inserts in old coal flues create creosote hazards. In pre-1950 Ewing neighborhoods near Trenton, homeowners install wood-burning inserts into flues never designed or relined for solid fuel. Heavy glazed creosote deposits accumulate beneath a cap that was never specified for that duty cycle - a fire hazard and a near-automatic code deficiency.

FAQs - Chimney Cap & Crown in Ewing
Yes, a multi-flue cap is almost always the better choice for Ewing’s shared-chase ranches and Cape Cods. Two separate caps leave the crown seam between them exposed, and wind-driven rain entering one flue can migrate down the shared masonry into the adjacent stack. We were called to a 1962 brick ranch off Bear Tavern Road where the cap had rusted through and water was staining the smoke chamber. When we ran a camera down the furnace side of the shared chase, we found the original clay tile had spalled to the point that flue gases from the fireplace were visibly bleeding into the furnace flue, so we set a stainless multi-flue cap sized to each flue opening and documented the cross-contamination on video before recommending any crown work. The homeowner watched the footage on our monitor on the tailgate and approved the cap that day - nothing else. Call (856) 388-5580 and we’ll inspect your chase configuration.
It depends on the depth and pattern of the cracking, which we determine by camera inspection and physical probe. Surface hairline cracks on a crown with sound structural integrity can often be addressed with crown coating at $320-$480. Crown coating is not appropriate when cracks penetrate to the flue seam, when edges are spalling, or when the crown has lost its positive slope - conditions we find frequently on Ewing’s 1950s-1970s chimneys after decades of Delaware River valley freeze-thaw. We’ll show you the footage and tell you straight which category you’re in. Call (856) 388-5580 for a free evaluation.
Because Ewing’s housing stock conceals problems that a ladder-top visual misses. The shared-chase configuration common in township ranches means a cap that fits the visible opening may be wrong for the actual flue diameter beneath, especially after gas conversions left original coal-era flues unlined. Our Level-2 camera inspection finds spalled tile, cross-contamination between flues, and creosote glazing that changes what cap or crown work is appropriate - and what is not. You review the footage before we quote. No camera evidence, no upsell. That’s the Keystone Standard. Call (856) 388-5580 to schedule.
Yes, it changes both the cap specification and the urgency of inspection. Wood inserts in unlined or improperly relined coal flues - common in pre-1950 Ewing neighborhoods near Trenton - produce heavy glazed creosote deposits that standard caps are not designed to vent. The cap must have adequate screen mesh and clearances for solid-fuel duty cycle, and the crown must be intact enough to prevent cooling airflow that worsens creosote condensation. More critically, this configuration is a near-automatic NJ code deficiency flag on home inspection reports. We document the flue condition by camera and specify the cap and any needed relining before you list or buy. Call (856) 388-5580 for an inspection.
A cap or crown alone rarely fixes draft problems. Draft issues in Ewing’s older chimneys usually stem from improperly sized flues after gas conversions, unlined stacks, or blockages we find during camera inspection - not from the cap itself. A new cap can stop water intrusion and animal entry, and a sound crown prevents further masonry deterioration, but if your flue was never relined for your current appliance, draft will remain poor regardless of cap quality. We diagnose the root cause by camera, show you the footage, and quote only what the chimney actually needs. Sometimes that’s cap and crown work. Sometimes it’s more. Either way, you’ll know before you spend. Call (856) 388-5580 for a free estimate.
