We’ve been answering calls with a live person, 24 hours a day, for over 42 years. Dispatch and scheduling for our Princeton crews are coordinated from our New York City office, and our technicians make the trip to Mercer County regularly. We know the difference between a routine liner job and the kind of shared-stack puzzle that shows up in the neighborhoods around Princeton University.

Princeton’s housing stock is different from what we see in Trenton or Bordentown. The historic district near Nassau Street contains an unusually dense concentration of 18th- and 19th-century homes built with lime-mortar masonry chimneys, many predating Portland cement. That means crumbling mortar joints, multi-flue stacks serving multiple original fireplaces, and preservation guidelines that restrict which relining methods are permissible. Our Chimney Liner & Rebuild team is trained for exactly this.

Why Hearthstone Chimney Co. Is Princeton’s Preferred Chimney Liner & Rebuild Company

Homeowners in Princeton call us because we document every inspection with photos and a plain-English verdict, and because our 90-Day Done Right Promise is backed in writing with no arguing. We’ve earned our reputation one chimney at a time.

Our technicians are background-checked and uniformed, and most jobs are completed in a single visit. When you’re dealing with a shared multi-flue stack on Library Place or Stockton Street, you want someone who has seen the problem before. We have. On Library Place, we rebuilt a crumbling lime-mortar chimney serving a Federal-era home’s two fireplaces and a neighbor’s gas vent. After a Level-2 inspection revealed a shared flue with cross-contamination and third-degree creosote, we installed a DuraFlex stainless liner for the wood fireplace and a separate Gelco liner for the gas appliance, then restored the crown to historic spec. The homeowners can now burn safely without smoke migrating between units.

We don’t cut corners with materials. Our crews carry professional-grade products from Olympia Chimney, Famco, Copperfield, and DuraFlex. No builder-grade substitutes. No surprises on the bill. The number on the estimate is the number on the invoice.

A live person answers every call, every hour of every day. Not a voicemail. Not a callback queue. If your chimney is backing up smoke or you smell gas from a shared flue, someone will pick up.

Our Chimney Liner & Rebuild Services in Princeton

Stainless Steel Liner Installation

We install DuraFlex and Olympia Chimney stainless steel liners for wood-burning and gas fireplaces throughout Princeton. These liners handle the heavy shoulder-season use common here, where homeowners burn from October through March on marginal nights that produce more creosote than deep-winter burning. In the attached homes near campus, we size each liner to prevent draft interference with neighboring flues.

Flexible Liner Installation

Flexible liners from DuraFlex navigate the offset flues and tight smoke chambers we find in Princeton’s colonial and Federal-era chimneys. Many of these stacks have settled or shifted over two centuries. A rigid liner won’t make the turn. We camera-inspect first, then select the right diameter and alloy for your appliance and fuel type.

Liner Replacement

This is our most common call in Princeton. Clay flue tiles crack from freeze-thaw cycles, and the mid-Atlantic pattern here is brutal: temperatures cross 32°F repeatedly, often multiple times in a single week. That spalls soft 19th-century brick and fractures terracotta faster than in consistently cold climates. We remove the damaged liner, clean the flue, and install a new stainless or flexible system sized to your fireplace. Every replacement includes a Level-2 camera inspection with photos you can see and a plain-English verdict before we quote.

Partial Chimney Rebuild

When the top courses of brick or the crown have failed but the lower structure is sound, we rebuild from the roofline up. In Princeton, this means matching original lime-based mortar, not modern Portland cement, which is too rigid for old soft brick and traps moisture. We also source period-appropriate chimney pots and caps for historic-district properties. Standard hardware-store caps won’t pass inspection near Nassau Street.

Full Chimney Rebuild

For chimneys with widespread structural failure, foundation settling, or multiple flues compromised by decades of deferred maintenance, we rebuild from the ground up. This is more common in the faculty rentals and multi-owner properties around Princeton University, where maintenance has been skipped between tenants. We handle permit coordination, historic preservation compliance where required, and full restoration of multi-flue function with proper separation between units.

Liner Repair

Minor cracks and gaps in otherwise sound liners can sometimes be sealed with HeatShield cerfractory foam, a product we apply with specialized pumps and verify with camera inspection. This is a cost-effective option when the damage is localized and the surrounding structure is sound. We don’t recommend it for liners with multiple fractures or in chimneys with active cross-contamination between flues.

Trusted Brands We Service in Princeton

We stock and install professional-grade materials from DuraFlex, Olympia Chimney, Famco, and Copperfield. Our Princeton crews carry common liner diameters, crown-forming materials, and period-appropriate cap styles on the truck, which means faster turnaround and fewer return trips for parts. For historic-district work near campus, we maintain relationships with specialty suppliers who can source reproduction terracotta chimney pots and decorative caps that meet preservation guidelines. No chasing down parts, no delays, no substituting with something that doesn’t belong on your house.

Common Chimney Liner & Rebuild Problems We See in Princeton Homes

• Neighbor’s appliance vents into a shared flue, causing cross-contamination and improper draft. In the attached homes near Princeton University, a single masonry chimney often serves multiple original fireplaces and sometimes a neighbor’s gas appliance. A liner replacement for one unit must prevent exhaust from migrating into an adjacent flue. Standard single-flue liner installs miss this entirely.
• Historic preservation rules near Nassau Street restrict liner materials and chimney cap styles. The guidelines covering much of the area around Princeton University limit which relining methods and exterior finishes are permissible. Non-compliant rebuilds fail inspection and must be redone. Our crews know the local constraints and spec work that passes the first time.
• Freeze-thaw cycles accelerate spalling in soft 19th-century brick. Princeton sits in the mid-Atlantic freeze-thaw belt, where winter temperatures repeatedly cross the 32°F threshold. Partial rebuilds fail within a few seasons if mortar isn’t matched to original lime-based mixes. We analyze the existing mortar composition and match it.
• Original decorative terracotta chimney pots are cracked from frost heave. On Mercer, Library Place, and Stockton, we regularly encounter these late-1800s pots. Standard brush rigs can shatter them. Replacing them to historic-district spec requires sourcing period-appropriate reproductions, not hardware-store caps. We know the suppliers.
