Why Lodi Residents Choose Us for HeatShield Service
Eleven years, one specialty. That’s the short version.
We’ve completed factory training on HeatShield’s Cerfractory and Cerflex liner systems, but we remain independent—no manufacturer affiliation, no forced parts quotas. We also handle HeatShield repair in Hasbrouck Heights. What that means for Lodi homeowners is we use genuine HeatShield materials where they solve the problem (Cerfractory foam for separating shared flues, Crown Saver for moisture-sealing spalled crowns) and fabricate custom stainless caps on-site where Lodi’s non-standard flue configurations demand it.
Gary Murphy grew up in Yonkers’ Nodine Hill neighborhood and learned the trade through Westchester Community College’s Building Trades program before spending years on real jobs across the Hudson Valley. His father was a finish carpenter, which is where Gary got the idea that a tradesman should look a homeowner in the eye and explain exactly what he found. Over 1,100 homeowners have trusted us with their chimneys, and Gary still climbs every roof himself rather than dispatching crews. In a borough like Lodi—where a single chimney stack often serves two families and liability questions get complicated fast—having the decision-maker on the ladder matters.
I’ll tell you what I see, not what sells.
Common HeatShield Chimney Cleaning Problems We Solve in Lodi
- Condensation-driven liner degradation in oversized clay-tile flues. Lodi’s 1970s–1980s oil-to-gas conversion wave left thousands of two-family homes with 8×12-inch clay-tile flues now venting small gas appliances. The chronic condensation this mismatch produces stains liners, rots cleanout doors, and drives the CO calls we see every winter in 07644. HeatShield’s Cerfractory foam liner resizes these flues properly, eliminating the pooling that destroys standard liners.
- Spalling brick at the roofline from freeze-thaw cycles. Bergen County’s repeated freeze-thaw cycles and nor’easters drive moisture into aging mortar joints, accelerating brick face loss. Lodi’s low-lying position near the Saddle River corridor keeps ambient moisture elevated year-round, compounding the damage. We address this with HeatShield Crown Saver applications and custom stainless flashing fabricated to fit each chimney’s actual condition.
- Cracked clay tiles from decades of thermal cycling. The post-WWII colonials and cape cods that dominate Lodi’s roughly one-square-mile footprint were built with original clay-tile liners now 60–80 years old. These tiles have opened mortar joints and through-cracks from repeated heating and cooling. Our Level 2 inspections document this damage with video, then we specify Cerfractory or Cerflex relining based on flue geometry and appliance load.
- Back-drafting between shared flues in two-family stacks. A single aging masonry chimney serving both dwelling units—often with adjacent or interconnected flues—creates cross-contamination hazards we don’t see in neighboring Bergen County towns. HeatShield’s multi-flue cap systems and proper liner separation restore safe venting paths.
- Incorrect flue sizing after oil-to-gas conversions. Many Lodi chimneys were oversized for coal or oil equipment later replaced with lower-BTU gas units. The resulting draft problems cause appliances to spill combustion gases into living spaces. We calculate proper flue sizing per National Fuel Gas Code and install HeatShield liners that match actual appliance output, not the original 1950s specification.
HeatShield Service in Lodi: What Local Conditions Mean for Your Equipment
Lodi’s low-lying grade near the Saddle River corridor keeps ambient moisture elevated year-round; combined with the borough’s 1970s-1980s oil-to-gas conversion wave, we frequently find condensation staining and rotted cleanout doors in the oversized 8×12-inch clay-tile flues that now vent small gas appliances—a moisture signature our HeatShield crews see consistently in this ZIP code.
This isn’t a theoretical problem. On a recent call in the two-family colonial blocks off Route 46, our crew arrived at a 1950s cape cod where both dwelling units shared a single masonry stack with two flues. The downstairs gas boiler was back-drafting through a cracked clay tile into the upstairs fireplace flue. We deployed a HeatShield Cerfractory foam liner to separate the flues, sealed the crown with Crown Saver, and installed a custom multi-flue cap—solving the CO hazard and ensuring the home met modern National Fuel Gas Code.
That job took a full day. A generalist sweep might have suggested a cheap stainless liner insert and called it done. We measured actual BTU loads, calculated draft requirements for both appliances, and built a system that works in Lodi’s specific moisture environment. The difference shows up three winters later when that chimney is still performing and the neighbor’s cut-rate job has already failed.
HeatShield Models & Products We Service in Lodi
We work with HeatShield’s full professional-grade product line, specifying based on what each Lodi chimney actually needs rather than pushing a one-size-fits-all approach, and we offer HeatShield in Garfield as well.
HeatShield Cerfractory Foam — Our go-to for resizing oversized clay-tile flues in Lodi’s converted two-family homes. Applied as a pumped slurry that cures to a ceramic-refractory finish, it creates a smooth, properly-sized venting path that eliminates the condensation pooling destroying original liners.
HeatShield Cerflex Roller-Applied Liner — Used where flue damage is extensive but structural integrity remains sound. The roller application allows precise thickness control in Lodi’s irregular, hand-laid masonry flues.
HeatShield Crown Saver — Critical for Lodi’s freeze-thaw environment. This flexible sealant bridges hairline cracks in concrete crowns, preventing the water intrusion that accelerates spalling in Bergen County winters.
HeatShield Multi-Flue Cap System — Essential for Lodi’s shared-stack two-family configurations. Properly sized and screened caps prevent cross-drafting while keeping out the debris and moisture that compound existing flue problems.
We stock genuine HeatShield Cerfractory and Cerflex materials for same-week relining jobs, and our mobile fabrication setup produces custom stainless caps and flashing for Lodi’s non-standard flue configurations—no waiting for out-of-town subcontractors.
HeatShield Service Pricing in Lodi
HeatShield chimney service in Lodi typically ranges from $1,200 for a straightforward Cerfractory foam relining of a single flue to $3,800 for complex multi-flue restoration with custom cap fabrication. Most Level 2 inspections with video documentation run $250–$400. Crown Saver applications average $450–$750 depending on crown condition and accessibility.
What drives cost: flue count, liner accessibility (some Lodi two-family stacks require scaffold work), extent of clay-tile damage, and whether custom stainless components are needed for non-standard configurations. Oil-to-gas conversions with significant oversizing issues require more material and labor than straightforward relining.
Every estimate includes a full Level 2 inspection with video, written condition report, and clear specification of recommended work. No charge for the visit, no pressure to commit on the spot. Call (844) 660-6590 to schedule—Gary Murphy will walk your property personally and give you numbers you can actually use.

FAQs — HeatShield Chimney Cleaning in Lodi
Yes. National Fuel Gas Code requires each appliance to vent through its own dedicated flue. In Lodi’s two-family colonials, we frequently find a single flue serving both a gas boiler and a fireplace, or two flues with cracked party walls allowing cross-contamination. We use HeatShield Cerfractory foam to create proper separation, then install multi-flue caps to maintain independent venting paths. Call (844) 660-6590 if you’re unsure about your stack configuration—we’ll inspect and document it.
Condensation from an oversized flue. Your clay-tile liner was sized for oil’s higher stack temperatures; the lower-BTU gas appliance can’t maintain adequate draft, so moisture condenses inside the flue and leaches through the masonry as brown staining. This is one of the most common calls we get in Lodi’s 07644 ZIP code. HeatShield’s Cerfractory foam liner resizes the flue to match your gas appliance’s output, eliminating the condensation source. Call (844) 660-6590 for a free inspection and exact quote.
Annually, per NFPA 211—and we’d push for that schedule given Lodi’s moisture load from the Saddle River corridor. Even properly installed HeatShield liners should be visually checked for new cracking, crown seal integrity, and cap condition after each heating season. The freeze-thaw cycles here are harder on masonry than inland Bergen County locations. We offer reminder scheduling so you’re not guessing.
Lodi Borough requires permits for liner replacement and any structural chimney modification. We handle permit applications as part of our project workflow, including the documentation Lodi’s Building Department requires for work on shared two-family stacks. The process typically takes 3–5 business days; we don’t start work until permits are in hand.
Chronic moisture intrusion combined with poor draft. The rusted cleanout door indicates standing water in the flue base; the summer creosote smell means gases aren’t venting properly and are condensing in the liner. In Lodi’s converted two-family homes, this pattern almost always traces to an oversized flue venting a gas appliance too small for the original clay-tile dimensions. We replace the cleanout door, install a properly-sized HeatShield liner, and seal the crown to stop water entry. Call (844) 660-6590—this condition creates real CO risk and shouldn’t wait.
