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 Repair - Bordentown for cap and crown work typically costs $280-$780 depending on whether you need a standard cap install, custom multi-flue cap, or crown coating on deteriorated masonry. Most jobs are completed in a single visit, and we carry the parts to do it. If you’re seeing crumbling mortar on your roof, water stains around the fireplace, or you share a chimney stack with a neighboring unit on Farnsworth Avenue, the problem usually gets worse with every freeze-thaw cycle.

We’ve been providing Bordentown Chimney Cleaning & Sweep services for over 42 years.

Our technicians are background-checked, uniformed, and trained to handle the unique challenges of 18th- and 19th-century masonry - soft colonial brick, lime mortar, and multi-flue stacks that were never designed for modern appliances. Scheduling and dispatch are coordinated from our New York City office, but our crews serve Bordentown locally and carry the materials to finish most jobs without a return trip.

Our Chimney Cap & Crown Services in Bordentown
Cap Installation
A proper chimney cap from our Fireplace Services in Bordentown is the first defense against water, animals, and debris entering your flue. In Bordentown, standard single-flue caps start around $280-$420 installed, including inspection and sizing. We use professional-grade caps from Famco and Copperfield - no builder-grade substitutes that rust out in three years. For homes on the bluff above the Delaware River, where northwest winds drive rain horizontally, we spec caps with extended skirts and wind-resistant designs that cheaper products can’t handle.
Cap Replacement
Most cap replacements in Bordentown run $320-$480. The old cap is removed, the flue opening is inspected for deterioration, and the new cap is secured with proper fasteners - not the cheap strapping that fails after one hard winter. We see a lot of failed DIY cap jobs in the historic district, where homeowners or handymen installed undersized caps that left gaps for water and squirrels. Done right, a replacement cap should outlast the next two roof cycles.
Crown Repair
Crown repair on Bordentown’s colonial-era chimneys typically costs $450-$680. The crown is the concrete or mortar wash that seals the top of the chimney where the flues exit. Original crowns on soft colonial brick were often poured too thin or with the wrong mix, and centuries of patching have left them cracked and porous. We remove the deteriorated material, form a proper slope for drainage, and pour a new crown with the correct Portland-cement-to-sand ratio - or we coat the existing crown if the damage is caught early enough.
Crown Coating
Crown coating with HeatShield runs $380-$580 and is often the right choice for Bordentown historic properties where full crown removal risks damaging irreplaceable antique brick. HeatShield is a ceramic refractory coating that seals hairline cracks and restores a waterproof, slightly flexible surface. It won’t save a crown that’s already crumbling, but for early-stage spalling - the white powdery surface you see on river-exposed chimneys - it adds years of life without the cost and disruption of full rebuild. We apply it in two passes, with a curing period between, and document the before and after with photos.
Multi-Flue Cap
Multi-flue caps are essential for Bordentown’s attached historic housing, where a single chimney stack serves two or more flues - sometimes for different properties. A custom multi-flue cap covers the entire chimney top with separate screened compartments for each flue, preventing cross-drafts and keeping rain out of unused or intermittently used flues. These run $520-$780 depending on size and material - galvanized steel, stainless steel, or copper. We measure on-site and fabricate to fit, because no two 200-year-old chimneys are identical.
Custom Cap
Custom caps for 18th-century chimneys in Bordentown’s historic district start at $620 and can reach $950 for large multi-flue copper installations. Historic preservation guidelines often require caps that don’t alter the roofline visibly or damage soft colonial brick with invasive fasteners. We fabricate custom solutions that mount securely without drilling into antique masonry, using straps, counter-flashing, or weight-based designs depending on the structure. Every custom cap job includes a written plan and photo documentation for your records and any preservation review.

Common Chimney Cap & Crown Problems We See in Bordentown Homes
- Crown face-spalling from river-corridor moisture. Bordentown sits on a bluff directly above the Delaware River, so chimneys here absorb elevated ambient moisture year-round. Combined with persistent northwest winds and severe winter freeze-thaw cycling, soft antique brick crowns face-spall noticeably faster than in inland towns just miles away. The white powdery surface you see is the brick literally disintegrating.
- Cross-contamination in shared multi-flue stacks. Because so many Bordentown historic-district homes are attached or tightly spaced along Farnsworth Avenue and the surrounding grid, adjacent properties often share multi-flue stacks - meaning a neighbor’s gas appliance can vent into the same chimney your fireplace uses. A missing or undersized cap allows exhaust to migrate between flues. This is a carbon monoxide risk that doesn’t exist in detached suburban housing.
- Centuries of mortar patching undermining new caps. The core of Bordentown City is dense with pre-Civil War homes whose chimneys have been patched repeatedly rather than properly rebuilt. A new cap installed on a crown with hidden substrate failure will leak within a season. We inspect the crown structure before capping, and we’ll tell you plainly if the foundation needs work first.
- Gas appliances vented into original unlined flues. Colonial-era homes in the historic district were often converted from wood to oil or gas heat decades ago, but the original unlined rubble-stone or soft-brick flues were simply left in place. Now they’re venting combustion appliances without any liner - a serious CO risk that comes up repeatedly on inspection calls in this zip code. A proper cap can’t fix an unlined flue, but it can prevent the draft problems that make a bad situation worse.
Our tech was called to a Federal-era rowhouse on Farnsworth Avenue where a new gas water heater had been tied into an original unlined soft-brick flue that also served the living-room fireplace. The crown was spalling badly from river-corridor moisture and northwest winds, and with the cap missing, the shared stack was pulling exhaust between units. We installed a custom multi-flue cap with separate ports for each appliance and coated the crown with HeatShield to seal the freeze-thaw damage - no more cross-draft, no more crumbling mortar on the roof.

What moves the number? Height and roof access - steep slate roofs on three-story rowhouses take longer and require additional safety rigging. The condition of the existing crown - a cap can only be as good as what it sits on. And whether the flue is lined or unlined, which affects what type of cap and venting solution we recommend.

FAQs - Chimney Cap & Crown in Bordentown
You may notice fireplace odors when your neighbor runs their furnace or water heater, or see soot staining in your firebox even when you haven’t burned a fire. The definitive check is a Level-2 camera inspection that traces each flue from top to bottom. We document what we find with photos and a plain-English verdict. If there’s cross-drafting, a custom multi-flue cap with properly separated compartments usually solves it. Call (856) 519-0832 for a free inspection.
Bordentown’s position on a bluff above the Delaware River exposes chimneys to persistent moisture and northwest winds that inland towns like Chesterfield don’t face. Winter freeze-thaw cycling is severe here, and soft colonial-era brick is already more porous than modern brick. The combination means face-spalling and crown cracking accelerate faster than just a few miles inland. A crown coating applied before major spalling begins can add significant life.
Yes - we regularly do this in Bordentown’s historic district. We avoid drilling into soft colonial brick whenever possible, using strap mounts, counter-flashing, or weight-based designs instead. Every custom installation is documented with photos for your records and any preservation review. We also provide a written plan before work begins so you know exactly how the cap will attach and what it will look like from the street.
No. An unlined masonry flue venting a gas appliance is a carbon monoxide risk and usually violates current code. The flue gases are acidic and will deteriorate the mortar further, and any gaps or cracks can leak CO into living spaces. A cap won’t fix an unlined flue, but it can be part of a complete solution that includes proper lining. We’ll show you camera footage of your flue condition and explain what needs to happen in what order. Nothing is recommended without photo evidence you can see for yourself.
Every 12 months for active fireplaces, and every 2-3 years for capped but unused flues - more frequently if the chimney serves a gas appliance in a shared stack. Bordentown’s river-corridor moisture and freeze-thaw cycling mean even good work needs periodic verification. The 90-Day Done Right Promise covers the installation itself, and we recommend scheduling a Level-2 inspection annually to catch any new issues before they become expensive. Call (856) 519-0832 to book.
