Wood and furnace flues brushed clean under HEPA vacuum, and the liner checked while it can actually be seen.
Sweep details
Stainless relining for cracked clay tile and the oversized oil-to-gas conversion flues all over the township.
Liner details
Ceiling rings, rusty dampers, and white-streaked brick traced back to the real entry point before anything is sealed.
Leak details
Original 1950s crowns torn off and re-poured with a real overhang, or coated where the slab is still worth saving.
Crown details
Original postwar joints cut out to depth and repacked in Type N mortar, tooled to disappear into the wall.
Repointing details
Step and counter flashing set into the mortar joint in metal, replacing the tar patches that keep failing.
Flashing details
Leaning and spalled stacks taken down to sound brick and rebuilt to match, from the roofline or the shoulder up.
Rebuild details
Stainless caps and full crown covers sized to the flue, bolted down, and screened against rain and animals.
Cap details
Breathable siloxane repellent on sound masonry, applied after repairs and never instead of them.
Waterproofing details
Level 1 and Level 2 inspections with a camera in the flue and a photo report you keep.
Inspection details
Level 2 camera documentation for NJ closings, scheduled fast and written up faster.
Certification details
Spalled and cracked brick cut out one unit at a time and replaced with matched stock that blends in.
Masonry details
Seized throat dampers freed or replaced, and top-sealing units fitted when the old cast iron is beyond saving.
Damper details
Raccoons, squirrels, and nest blockages out humanely, then stainless mesh over the flue so it never repeats.
Removal details
Firebox joints repacked in refractory mortar, prefab panels replaced to spec, and gas sets sorted honestly.
Fireplace details
The whole duct brushed end to end, the lint captured, and the airflow measured to prove the run is open.
Vent detailsHow a job runs
We get on the roof, scope the flue, and photograph what we find, including the parts you can’t see from the driveway.
A line-item scope with the materials named. Fixed price before work starts, no allowance padding.
Drop cloths inside, staged access outside, mortar mixed to match. Most jobs run one to three days.
Before-and-after photographs of the finished work, so you can see what you paid for.
Materials
Clay flue tile gets replaced with clay tile or a listed 316Ti stainless liner, sized to the appliance it serves and insulated to keep flue temperatures where they belong. An oversized flue is the problem as often as a cracked one. Caps are stainless too, fixed to the tile or the crown, with mesh sides that keep rain, birds, and nesting debris out while the flue still draws.
Crowns are poured with a proper overhang and drip edge, or coated with a flexible crown sealant when the slab is sound but hairlined. Repointing is done in Type N mortar, softer than the brick, the way the original joints were mixed. Flashing is stepped and counter-flashed into the mortar joint, never smeared with roof tar, and brick and stone get a vapour-permeable siloxane sealer that lets the wall dry out.

Questions
It depends on what failed and how high up it failed. A cap or a crown coat sits at the small end, repointing and brick replacement in the middle, and liners or rebuilds at the top. Because so much of the township is the same few 1950s chimney designs, we can usually scope the likely work from a photo, and every job gets a written line-item price before anything starts. Estimates are free.
More than ever. Gas exhaust is cooler and wetter than the oil exhaust the flue was built for, so it condenses inside the oversized clay liner and slowly breaks down the tile joints and mortar. Most township houses made this conversion decades ago, and the flues were rarely resized. A camera inspection shows whether yours needs a properly sized stainless liner.
When a furnace is replaced with a high-efficiency unit that vents out the sidewall, the water heater is often left venting alone into a masonry flue sized for both appliances. Its small exhaust cannot keep that much flue warm, condensation takes over, and the chimney deteriorates from the inside. The fix is a liner sized to the water heater, and it is one of the most common jobs we do here.
The brick structure is usually still sound, but the wear parts are due. Original crowns, mortar joints, dampers, and clay flue liners are now roughly seventy years old, and they age on a similar schedule from Iselin to Fords because the houses went up together. Catching a failing crown or receding joints early is the difference between a modest repair and a rebuild.
Yes. Woodbridge proper, Iselin, Colonia, Fords, Avenel, Sewaren, Port Reading, Hopelawn, and Keasbey are all home territory, and we also work the neighboring towns, including Edison, Metuchen, Carteret, Perth Amboy, Rahway, and Sayreville. Same crew, same pricing, whichever side of the Parkway you live on.
Very often, in practice. Buyers' inspectors flag chimneys on older homes as a matter of routine, and attorneys or insurers then ask for a Level 2 camera inspection with documentation. On the township's 1950s housing stock with original liners, expect the chimney to come up during attorney review, and get it documented early so it never threatens the closing date.
Woodbridge and the surrounding towns. If it is not ours to fix, we will say so.
