Fast, Reliable Chimney Liner & Rebuild Across University Heights
University Heights sits in the northwest Bronx, a dense grid of pre-war brick walk-ups and elevator buildings where chimney systems work harder than most New Yorkers realize. If you own or manage one of these 1920s-1940s multi-family buildings along Sedgwick Avenue or near the Jerome Park Reservoir, you’ve likely got a shared masonry chimney stack with clay tile flue liners that were never designed for today’s gas appliances. We’re Hearthstone Chimney Co., and we’ve been relining and rebuilding chimneys in Bronx neighborhoods like yours for over 42 years. Most calls from our University Heights service area get same-day or next-day response. Call (844) 803-1545 - a live person answers, 24 hours a day.
Why Hearthstone Chimney Co. Is University Heights’s Preferred Chimney Liner & Rebuild Company
We’ve worked on chimney stacks from West 183rd Street to Bailey Avenue long enough to know which buildings share flues, which have undocumented modifications from the 1970s oil-to-gas conversions, and which landlords got surprised by NYC DOB permit requirements they didn’t know existed. That knowledge saves time and prevents red-tag situations.
Our University Heights customers tell us they chose us because we document everything. Our Level-2 camera inspections end with photos you can see and a plain-English verdict - no jargon, no scare tactics, just what is wrong and what it takes to fix it. We’ve earned a strong local reputation across Bronx neighborhoods for showing up when we say, finishing most jobs in a single visit, and standing behind our work with our Fireplace Services in University Heights and the 90-Day Done Right Promise in writing.
Response time matters in buildings where multiple families share heat. When a liner fails mid-winter, we’re typically on-site in University Heights within hours, not days. Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most relining and rebuild work without a return trip.
Our Chimney Liner & Rebuild Services in University Heights
Our Chimney Liner & Rebuild team handles the full scope of liner and masonry work for University Heights’s distinctive multi-family housing stock. Here’s what we do most often in your neighborhood:
Stainless Steel Liner Installation
For University Heights buildings with deteriorated clay tile flues serving modern gas boilers, we install rigid or semi-rigid stainless steel liners sized precisely to the appliance’s BTU output. This solves the chronic condensation and draft failure we see in oversized flues above Jerome Park and along Sedgwick Avenue. A properly sized stainless liner eliminates the backdraft risk and brings the system into compliance with current fuel-gas codes. Most installations in 5-6 story walk-ups run $2,800-$4,500 depending on flue height and access.
Flexible Liner Installation
Some University Heights chimney stacks have offsets or bends from century-old construction that rule out rigid liners. We use DuraFlex and Olympia Chimney flexible stainless products that navigate these irregular flues while maintaining proper draft. Flexible liners are particularly useful in buildings near the reservoir where chimney structures have settled over decades. Typical flexible liner jobs in University Heights run $2,200-$3,800.
Liner Replacement
When a clay tile liner has partially collapsed or shows spalling from freeze-thaw damage - common after harsh Bronx winters - partial or full replacement is the only code-compliant path. We remove the damaged sections and install new liners matched to the heating appliance, not the original coal-era dimensions. In University Heights’s shared-stack buildings, we coordinate with building management to minimize disruption to residents. Liner replacement projects typically range $1,800-$3,200 for single-flue systems, $3,500-$6,000 for multi-flue stacks.
Partial Chimney Rebuild
The exposed chimney crowns above University Heights’s flat roofs take a beating. Repeated freeze-thaw cycles crack mortar and spall brick, letting water infiltrate and destroy liners from the outside in. We rebuild our Chimney Cap & Crown in University Heights, shoulders, and upper courses with matching brick and proper crown slope and drip edges to shed water. A partial rebuild addressing crown and upper stack damage typically runs $1,500-$3,000 in this market.

Trusted Brands We Service in University Heights
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, Olympia Chimney, and Famco - brands that meet UL 1777 standards and hold up in hard-use Bronx heating systems. Because we stock these parts locally, University Heights building owners aren’t waiting two weeks for a liner shipment while their boiler sits idle. When we inspect your flue, we know immediately whether we can line it, what diameter and length we need, and whether we’ve got it on the truck. That is how most jobs get done in a single visit.
Common Chimney Liner & Rebuild Problems We See in University Heights Homes
- Oversized flues causing condensation damage. The original clay liners in your 1920s building were sized for coal, later adapted for oil, and now serve low-BTU gas appliances. That mismatch produces acidic condensation that erodes mortar and stains interior flue walls. We measure the appliance output and install a liner that fits the fuel, not the history.
- Freeze-thaw spalling on exposed chimney crowns. University Heights’s January and February temperatures regularly drop below freezing for weeks at a time. Water trapped in porous brick and mortar expands, cracks, and flakes off surface material. Once the crown fails, water runs straight down the flue and accelerates liner collapse.
- Undocumented shared flues and illegal modifications. In buildings converted from coal to oil to gas across eight decades, we’ve found flues serving multiple units through unlisted connectors, abandoned laterals partially blocking draft, and clay tiles cracked by thermal shock from decades of mismatched use. Our camera inspection finds what the naked eye cannot.
- DOB compliance gaps that block repairs. Many University Heights owners discover too late that NYC DOB requires a filed permit and licensed contractor for chimney relining in multi-family buildings. A handyman patch is not legal. We file permits properly and document code compliance, protecting owners from violations and liability.
