Why Westwood Residents Choose Us for HeatShield Service
We’ve been working on Bergen County chimneys for 11 years, and Westwood’s housing stock keeps us busy year-round. Gary Murphy, our owner and lead technician, 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. He still climbs every roof himself — not something you’ll get from a franchise dispatch.
That matters for HeatShield work specifically. These systems require precise surface prep and exacting application of the ceramic liner slurry. A tech who’s only done a handful won’t recognize when a Westwood chimney’s oversized flue — originally built for coal — needs custom baffling to prevent the liner from bridging. We’ve completed hundreds of HeatShield in Hillsdale and throughout Bergen County, and we’ve learned to spot the failure patterns that show up repeatedly in Westwood’s 1920s–1950s construction.
Our 1,142 verified reviews averaging 4.7 stars reflect that hands-on approach. We use genuine HeatShield Crown Seal System materials, factory-manufactured ceramic liner segments, and OEM termination caps — never aftermarket substitutes that void the system’s integrity. “I’ll tell you what I see, not what sells.” That’s been our operating principle since day one.
Common HeatShield Chimney Cleaning Problems We Solve in Westwood
- Bridging or incomplete Crown Seal — Westwood’s freeze-thaw cycles, with temperatures crossing 32°F dozens of times each winter, aggressively spall brick crowns. When the Crown Seal System is applied over deteriorated masonry without proper resurfacing, it bridges across gaps rather than bonding to sound substrate. Water infiltrates, freezes, and detaches the liner from the flue wall. We see this constantly on the low-pitched roofs near Pascack Brook, where crown damage goes unnoticed until the liner fails.
- Premature ceramic liner cracking in converted gas flues — Those oversized chimneys built for coal, then oil, now vent condensing natural gas exhaust. The acidic moisture attacks HeatShield’s ceramic liner segments faster than the product’s rated lifespan predicts. In Westwood’s unlined Colonials, we regularly find cracked segments within 5–7 years instead of the expected 15+. The fix isn’t thicker liner — it’s proper sizing and sometimes a stainless steel DuraFlex insert for the worst cases.
- Cross-contamination in collapsed multi-flue partitions — Westwood’s dual-use chimneys, serving both furnace and fireplace from a single brick enclosure, depend on terra-cotta dividers that weren’t built to last a century. When that partition crumbles, cleaning one flue without inspecting the other violates code and creates real carbon monoxide risk. Our Level 2 camera inspections catch this before a routine sweep makes it worse.
- Efflorescence at the crown-to-liner interface — Ground-level humidity from the Pascack Brook valley wicks into mortar joints, carrying salts that bloom white at the liner edge. This isn’t cosmetic. It signals active moisture intrusion that’s degrading the bond between HeatShield materials and original masonry. Left alone, the liner separates and the chimney begins shedding interior mortar into the flue.
- Improper joint alignment in multi-flue installations — Some contractors treat a double-flue chimney like two separate jobs. It’s not. The furnace chase and fireplace chase share thermal mass and draft dynamics. Misaligned HeatShield joints between flues create turbulence, backdrafting, and the soot stains Westwood homeowners sometimes notice on their exterior brick after a windy day.
HeatShield Service in Westwood: What Local Conditions Mean for Your Equipment
Westwood’s Broadway commercial district and surrounding residential blocks were largely built during a 1920s–1950s boom, leaving a stock of brick Colonials and Cape Cods with double-flue chimneys originally sized for coal. Today, many of these chimneys lack any flue liner, posing an acute carbon monoxide risk when gas appliances are vented into them — a danger our Level 2 inspections routinely uncover.
This isn’t abstract. We cleaned a HeatShield-lined double-flue chimney for a Dutch Colonial on Park Avenue, just south of the Pascack Valley rail line. During the Level 2 inspection, we found that the terra-cotta partition between the furnace and fireplace flues had collapsed, allowing creosote and soot to cross-contaminate both flues. Our crew installed a new multi-flue cap and sealed the partition breach using our Old Tappan HeatShield service ceramic liner system, restoring safe separation and proper draft. Without that inspection, the homeowner would have kept using a fireplace that was slowly filling their furnace flue with combustible deposits.
That job illustrates why HeatShield work in Westwood demands more than product knowledge. It requires reading the specific pathology of 07675’s building stock — the coal-era flue dimensions, the deteriorated partitions, the humidity patterns off Pascack Brook — and matching the right HeatShield application to the actual condition. Generic relining contractors miss this. They’ll sell you a liner that fits technically but fails functionally because it doesn’t account for how your specific chimney breathes.
HeatShield Models & Products We Service in Westwood
We work with the full HeatShield product line, applying each system to the specific failure mode it was designed to address:
- Crown Seal System — For spalled or cracked crowns on Westwood’s older brick chimneys, applied after proper resurfacing of damaged masonry
- HeatShield Ceramic Chimney Liner — The patented slurry liner for restoring sound but unlined or partially lined flues; our primary solution for Westwood’s common unlined coal-era chimneys
- HeatShield Access Doors — Installed for future inspection and maintenance access, critical on multi-flue installations where both furnace and fireplace need ongoing service
- HeatShield Termination Caps — OEM caps sized to prevent wind-driven down-drafts on Westwood’s exposed low-pitched rooflines
We stock genuine HeatShield materials for fast turnaround on Westwood jobs — no waiting on factory shipping for standard repairs. If your chimney is beyond what HeatShield can safely restore, we’ll tell you directly and recommend full rebuilding with DuraFlex or Olympia Chimney stainless systems rather than patching what’s failing.

FAQs — HeatShield Chimney Cleaning in Westwood
Yes — in fact, that’s exactly what it was developed for. The ceramic slurry bonds directly to sound masonry, creating a seamless liner where none existed. In Westwood’s unlined Colonials and Cape Cods, we use it frequently, but only after confirming the chimney structure can support the application. Severely spalled or shifting walls need rebuilding first. Call (844) 660-6590 and we’ll inspect yours at no charge.
Annual inspection is non-negotiable; cleaning frequency depends on use. A fireplace-burning household in Westwood should sweep yearly before the heating season. Gas-only flues with HeatShield liners need less frequent cleaning but still require inspection for condensate damage — especially given Bergen County’s wet winters and the acidic exhaust from modern high-efficiency furnaces. We check liner integrity during every service. Schedule your pre-season inspection at (844) 660-6590.
Absolutely, and this is where our experience with Westwood’s specific building stock matters. The key is maintaining proper separation between flues. We install HeatShield liners with dedicated access doors for each flue, and where partitions have failed, we rebuild separation using ceramic liner materials before applying the main flue coating. The multi-flue cap installation completes the system. Gary Murphy personally verifies joint alignment on every double-flue job.
HeatShield’s factory warranty covers materials against manufacturing defect; our workmanship is guaranteed for 5 years on liner applications and 3 years on Crown Seal repairs. The warranty is transferable if you sell your Westwood home — a detail that matters in this market. We document every installation with pre- and post-condition photos to support any future claim. Keep your service records; they’re your proof of proper maintenance.
Often yes, but not automatically. An unlined brick chimney venting a gas furnace is a carbon monoxide risk — period. HeatShield’s ceramic liner can resolve this if the chimney structure is sound and the flue isn’t oversized to the point of persistent condensation. In Westwood’s coal-era chimneys, we sometimes pair HeatShield with a stainless steel insert (DuraFlex or Olympia Chimney) when the dimensions are too large for ceramic alone. The inspection tells us which path is right. Call (844) 660-6590 for a free evaluation — this isn’t a situation to delay.
