HeatShield Chimney Cleaning in Franklin Square, NY

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

HeatShield Chimney Cleaning in Franklin Square, NY | Top Hat Chimney

We provide independent HeatShield service across Franklin Square, from our Chimney Cleaning & Sweep in Franklin Square and camera inspection to full Cerfractory rebuilds. The one thing that makes our HeatShield work different here is that we know these chimneys carry oil-heat history, and abandoned flues from gas conversions create failure patterns a generic sweep will miss. If your HeatShield liner is acting up or you just want it checked before burning season, call (516) 963-1068 and we’ll give it to you straight.

Why Franklin Square Residents Choose Us for HeatShield Service

HeatShield’s Cerfractory products have been the go-to relining fix in Nassau County for over twenty years, and our crews have serviced them in Franklin Square’s postwar Capes and ranches since the beginning. Wendell Pike has spent the better part of two decades driving out to Hempstead and the surrounding neighborhoods, including plenty of calls near Hofstra University where older homes and older chimneys go hand in hand. He learned the trade at Southwestern College in Chula Vista, picked up the rest on actual rooftops, and has been cleaning and inspecting chimneys long enough that he stopped counting flues somewhere around year ten - though he still takes pride in every Chimney Repair - Franklin Square homeowners trust us with.

We’re an HeatShield sales & service provider in the sense that we install and repair their systems. We are not manufacturer-authorized, and we won’t pretend otherwise. What that means for you: we use HeatShield’s OEM Cerfractory material and proper mixing equipment, because off-brand sealants cannot match its expansion characteristics or bond strength in Nassau County’s temperature swings. The number you hear on the phone is the number on the invoice. And every job carries the 90-Day Done Right Promise in writing.

Common HeatShield Chimney Cleaning Problems We Solve in Franklin Square

  • Cracked terra-cotta behind the HeatShield surface. Franklin Square homes built between 1945 and 1965 still carry original clay liners that are now 60 to 80 years old. HeatShield applied over old tile with existing gaps can pull away at the tile joints, and most homeowners never know until we run a camera. That’s why we camera-inspect before patching anything.
  • Delamination from water intrusion at the crown. Nor’easters drive rain horizontally into chimneys all over Franklin Square. If the crown has open mortar joints, water works its way behind the HeatShield surface and creates hidden voids. We find this constantly after a rough winter.
  • Crumbly Cerfractory from a botched original mix. We’ve seen original HeatShield jobs where the mixing ratios were off. The plugs never fully cure, and they spall under Nassau County’s freeze-thaw cycling. Salt-laden air only speeds it up.
  • Acidic soot eating unprotected mortar in the smoke chamber. If an original HeatShield job skipped smoke chamber parging, leftover acidic oil-flue soot attacks the mortar behind the liner. This is a Franklin Square-specific problem because so many of these homes burned heating oil for decades.
  • Abandoned oil flues hiding inside shared chimneys. When a home switched from oil to gas, the old oil flue often got left open, uncapped, and forgotten. Rain and squirrels get in. The open flue channels moisture directly behind the HeatShield surface on the adjacent flue. More on that below.

HeatShield Service in Franklin Square: What Local Conditions Mean for Your Equipment

Franklin Square’s housing stock is almost entirely post-World War II Capes and ranches built between 1945 and 1965, and Long Island has one of the highest concentrations of heating-oil-dependent homes in the country. That means most of these 60 to 80-year-old masonry chimneys served oil burner flues, not wood fireplaces. Oil flue chimneys accumulate sulfurous, acidic soot that attacks terra-cotta liners differently than wood creosote. When a HeatShield liner went in during an oil-to-gas conversion and the old oil flue was never capped, the liner is now protecting a live gas flue alongside a dormant channel that’s open to rain, squirrels, and freezing water. On Madison Street North last March, our tech opened a chimney where a previous owner had a HeatShield Cerfractory liner installed during an oil-to-gas swap, but the old oil flue was left uncapped. After a nor’easter, the open flue channeled water behind the HeatShield surface and caused a 4-foot delamination along the shared wythe. We camera-scoped the void, cut out the loose material, rebuilt that section with fresh Cerfractory, and capped the abandoned flue with a custom multi-flue cap. The gas flue now drafts clean and the crown stays dry. If it doesn’t need doing, we’ll tell you. But in Franklin Square, you should know your heating history before you trust that liner.

HeatShield Models & Products We Service in Franklin Square

We work on the full HeatShield product family: the Cerfractory Flue Sealant, the Joint Repair System, the Resurfacing System, and the Rebuild System. Each one addresses a different level of damage, and the wrong choice is a waste of your money. We stock HeatShield OEM Cerfractory material and proper mixing equipment for Franklin Square jobs, which keeps turnaround tight. If delamination or structural movement exceeds a third of the flue, we recommend a full rebuild rather than another surface patch. We’ll show you the camera footage so you can see exactly why.

HeatShield Service Pricing in Franklin Square

A Level 2 camera inspection in Franklin Square typically runs $195-$325. Joint repair work starts around $400-$700 depending on access. A full resurfacing job on a standard single flue runs $2,500-$5,000. A complete rebuild runs $4,000-$8,000+. Prices move with the height and condition of the chimney, how much scaffolding is needed on a tight Franklin Square lot, and whether we’re repairing one flue or rebuilding a multi-flue stack. Every estimate starts with the camera and a plain-English explanation of what we found. Call (516) 963-1068 to schedule a free estimate.
