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 Princeton’s Preferred Chimney Liner & Rebuild Company
We’ve been answering calls with a live person for over 42 years, and that steady presence matters in a town where homeowners stay put for decades. Princeton residents don’t want a different technician every season - they want someone who remembers their chimney from last year and knows why the crown on their Hodge Road Victorian keeps failing.
Our Level 2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your chimney can safely wait another season, we’ll say so plainly. The 90-Day Done Right Promise backs every liner and rebuild job in writing - if it’s not right, we come back, no arguing, no paperwork chase.
Background-checked, uniformed technicians carry professional-grade materials from DuraFlex, HeatShield, and Gelco on every truck. Most liner installations and partial rebuilds finish in one visit with no-hassle upfront pricing - the number on the estimate is the number on the invoice.
We understand Princeton’s specific conditions: the shared flue stacks in the historic core, the preservation review requirements for work visible from the street, and the portland-cement repairs that well-meaning past owners applied to soft-lime original construction. That local fluency saves time and prevents callbacks.
Our Chimney Liner & Rebuild Services in Princeton
Stainless Steel Liner Installation
A stainless steel liner from DuraFlex is the standard solution for Princeton’s unlined or deteriorated clay-tile flues, especially in the multi-flue chimneys common around Library Place and Mercer Street. We size the liner to your appliance - fireplace, insert, or furnace - and install it with proper insulation to meet NFPA 211 standards. In Princeton’s historic district, we document the work with photos for any preservation review that may apply. A typical stainless steel liner installation in Princeton runs $2,800-$4,500.
Flexible Liner Solutions
Flexible liners navigate the offset flues and tight bends we encounter in Princeton’s older homes, particularly where 19th-century brickwork has settled or shifted. We use DuraFlex flexible products when a rigid liner won’t make the turn, and we always verify proper draft performance before leaving. Flexible liner installation in Princeton typically costs $3,200-$5,000 depending on length and access.
Liner Replacement
When an existing liner has cracked, separated, or corroded - common in Princeton chimneys that saw mid-century coal-to-gas conversions - full replacement is the only safe option. We remove the failed liner, inspect the surrounding masonry for hidden damage, and install a new system sized to current code. Liner replacement in Princeton generally runs $3,500-$6,000, with multi-flue stacks at the higher end.
Partial Chimney Rebuild
Many Princeton chimneys need crown, shoulder, or upper-course rebuilds before any liner work is safe to complete. The portland-cement repointing and caps applied during 20th-century maintenance trap moisture against aging brick, accelerating spalling faster than the original lime mortar ever did. We rebuild with proper lime-based mortar where historic appropriateness matters, and with modern equivalents where function is the priority. Partial rebuilds in Princeton typically cost $2,500-$5,500.
Full Chimney Rebuild
When freeze-thaw damage, structural settling, or decades of deferred maintenance have compromised the entire stack, we rebuild from the roofline up or from the foundation, depending on condition. Full rebuilds in Princeton’s historic core require careful material matching and sometimes preservation review coordination. These projects range from $8,000-$15,000+ and are scheduled with weather protection for your home.
Liner Repair
Minor liner damage - localized cracks, joint separation, or small breaches - can sometimes be addressed with HeatShield cerfractory sealant rather than full replacement. We only recommend repair when camera evidence shows the surrounding liner is sound and the breach is accessible. Liner repair in Princeton runs $1,800-$3,200 when it’s a viable option.

Common Chimney Liner & Rebuild Problems We See in Princeton Homes
- Shared-stack cross-contamination. Many Princeton chimneys in the historic core contain multiple flues in a single masonry chase, and a cracked or missing flue divider lets a neighbor’s furnace exhaust migrate into your fireplace flue. Our Level 2 inspection maps every flue in the stack before any liner work begins.
- Portland-cement trap. Mid-century repairs with portland cement rather than original lime mortar seemed sensible at the time, but the harder material traps moisture against soft brick. We regularly remove these failing caps and repoint with compatible mortar before installing new liners.
- Freeze-thaw and debris damage. Princeton’s protected tree canopy drops significant leaf accumulation each fall, and Central New Jersey’s freeze-thaw cycle opens mortar joints that leaf debris then wedges wider. Only a Level 2 camera inspection reveals the liner breaches this causes.
- Coal-to-gas conversion damage. Original unlined flues or early clay liners were never designed for the cooler, wetter exhaust of modern gas appliances. We find glazed creosote, deteriorated mortar, and breached dividers throughout the older neighborhoods near the university.

FAQs - Chimney Liner & Rebuild in Princeton
No, shared-flue conditions between separate dwelling units violate current NFPA and IRC codes, and they’re surprisingly common in Princeton’s historic core where 19th-century multi-flue stacks serve attached or adjacent properties. The cracked divider between flues lets exhaust gases and creosote migrate, which is why our Level 2 inspection maps every flue in your stack before we quote any liner work. Call (856) 388-5580 for a free inspection - we’ll show you the camera footage and explain exactly what needs separation.
Portland-cement crowns and repointing applied during 20th-century maintenance trap moisture against the original soft-lime brick, accelerating spalling that destabilizes the entire upper chimney. We can’t safely install a liner in a stack whose crown is actively shedding brick and mortar into the flue. The crown rebuild comes first, done in proper lime mortar where historic standards apply, then the liner goes in on solid masonry. Most crown rebuilds in Princeton run $2,500-$4,200.
Work visible from the public right-of-way in or adjacent to the Princeton Historic District may require preservation review, particularly for full rebuilds or material changes to the chimney exterior. We document every project with dated photos, material specifications, and installation details to support any review process. Most liner-only installations, being internal, don’t trigger review, but we always flag the possibility during our initial inspection so you’re not surprised later.
Annual Level 2 inspection is the right interval for Princeton’s conditions - the mature tree canopy deposits debris that accelerates crown deterioration, and Central New Jersey’s freeze-thaw cycle opens new mortar joints every winter. Homes with active fireplaces, gas inserts, or vented appliances sharing historic stacks should not skip years. Call (856) 388-5580 to book; estimates are free.
Third-degree creosote is a hardened, tar-like glaze that forms when wood smoke condenses in a cool or restricted flue - common in Princeton’s older, unlined or partially lined chimneys. Standard brushing won’t remove it; the glaze is bonded to the masonry or old liner surface and requires chemical treatment or mechanical removal, sometimes with a rotary system. In severe cases, the flue is damaged enough that liner replacement is the only safe solution. We determine the extent with our camera inspection before recommending the right approach.
