Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Repair Across Paramus
Chimney repair in Paramus typically runs $350-$2,800 depending on whether you need mortar repointing, crown rebuilding, or full chimney reconstruction, and most jobs are completed in a single visit with our crew. If your home is one of the borough’s thousands of 1950s-1970s split-levels or colonials near Farview Avenue, Century Road, or along the Route 4 corridor, your masonry chimney is likely 50-70 years old and showing the predictable wear of that era’s construction. Call us at (973) 604-2986 - a live person answers 24 hours a day, and we’ll schedule your free estimate at a time that works for you.
We’ve worked on Paramus chimneys long enough to know the local patterns: the shared two-flue chases built for oil furnace and fireplace, the freeze-thaw damage from Bergen County’s wet winters, and the particular headache of under-fired gas appliances in oversized clay flues. Our Chimney Repair team doesn’t guess. We run a Level 2 camera inspection, show you the photos, and give you a plain-English verdict before any work begins.
Why Hearthstone Chimney Co. Is Paramus’s Preferred Chimney Repair Company
We’ve been serving Bergen County homeowners for over 42 years, and Paramus represents one of the most concentrated pockets of mid-century chimney stock in northern New Jersey. That density of aging masonry means we’ve seen nearly every failure mode this borough can produce - shared-stack cross-contamination, spalled crowns from decades of freeze-thaw, and the acidic liner degradation that follows oil-to-gas conversions.
Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most repairs in a single visit. No waiting on parts, no return trips, no surprises on the bill. The price we quote is the price you pay.
Every job is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we make it right. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.

Our Chimney Repair Services in Paramus
Chimney Rebuilding
Some Paramus chimneys have simply reached the end of their serviceable life. The original single-wythe brick, the mortar mixed to 1960s standards, and the clay tile liners installed when Lyndon Johnson was president - it all adds up to a structure that no amount of patching will save. On a split-level off Farview Avenue near Paramus High School, our tech opened a 1968 chase and found the fireplace flue sharing the stack with an abandoned oil flue whose clay tiles had spalled and were dropping debris onto the smoke chamber ledge of the adjacent fireplace liner. We did a Level 2 inspection, installed a HeatShield-resurfaced fireplace liner with a new stainless cap, and repointed the crown to stop the water that had been feeding the spalling. Full rebuilding runs $1,800-$2,800 in Paramus, depending on height, access, and whether the foundation needs attention.

Flashing Repair
The junction where your chimney meets the roof is the single most common leak point we find in Paramus homes. The borough’s flat Hackensack River valley topography offers no wind-break, so driving rain hits those seams directly. Original flashing on a 1960s Paramus colonial was often step-flashing with a simple counterflap, and decades of thermal cycling have opened gaps you can’t see from the ground. We remove the old material, inspect the deck beneath, and install new copper or stainless flashing integrated with your roofing system. Most flashing repairs in Paramus run $450-$850. We document the before condition with photos, and we show you the completed work.

Chimney Waterproofing
Bergen County’s freeze-thaw cycle crosses 32°F 60-80 times each winter, and Paramus’s original single-wythe brick is wide open to water intrusion. Once moisture enters, it expands on freezing, spalling faces off bricks and turning mortar to sand. We apply a vapor-permeable waterproofing treatment - never a film-forming sealer that traps moisture inside - after any necessary repointing is complete. A typical waterproofing job on a Paramus split-level chimney runs $650-$1,200, including minor mortar repair. The treatment carries a 10-year warranty and stops the water that feeds freeze-thaw damage.

Mortar Repointing & Tuckpointing
The mortar joints on a 55-year-old Paramus chimney have endured roughly 3,000 freeze-thaw cycles. When we grind out the deteriorated material and repoint with color-matched, properly compressed mortar, we’re not just cosmetically refreshing the face - we’re restoring the structural bond that keeps the stack square and stable. Tuckpointing, where we cut fine decorative lines into the new mortar for a crisp appearance, is available where the brick itself is sound. Repointing on a typical Paramus chimney runs $800-$1,600.

Spalling Brick Repair
Spalled brick - the flaked, popped faces you see on so many Paramus chimneys - is not a surface problem. It’s a symptom of water saturation and freeze-thaw destruction from within. We remove spalled units, source matching replacement brick where possible, and address the water source before we close the wall. Individual brick replacement runs $150-$350 per unit in Paramus, with most jobs involving 5-15 bricks.

Trusted Brands We Service in Paramus

Common Chimney Repair Problems We See in Paramus Homes
- Shared-chase cross-contamination. Nearly every Paramus chimney on the borough’s 1950s-70s split-levels and colonials was originally built as a two-flue masonry chase - one flue for the fireplace, a second for the oil furnace - and since those furnaces began being swapped for high-efficiency gas, the original clay tiles have gone cold and wet, so we now find acidic, creosote-like deposits degrading the flue liner from the inside in a way that never happened when the furnace itself kept the stack warm. The adjacent fireplace flue can draw those contaminants across.
- Under-fired gas appliance in an oversized clay flue. When a Paramus homeowner converts from oil to high-efficiency gas, the new appliance sends cooler exhaust up a flue designed for 400°F oil combustion. The flue never warms enough to stay dry. Condensation forms, acidic deposits accumulate, and the clay tile liner rots from the inside out. We find this constantly in Paramus; it’s far less common in newer-build towns.
- Freeze-thaw spalling at the crown and mortar joints. The Hackensack River valley’s flat, wet exposure leaves chimney crowns and caps unprotected from sustained weather. Temperatures cross 32°F dozens of times each winter. Water enters hairline cracks, expands, and opens them wider. By spring, the crown is crumbling and mortar is falling out in grains.
- Abandoned oil flues dropping debris into active fireplace flues. In attached homes and split-levels throughout the neighborhoods near Paramus High School and along Midland Avenue, we’ve opened chimneys to find the abandoned furnace flue shedding spalled tile and mortar onto the smoke chamber ledge of the still-active fireplace flue below. The homeowner smells something wrong but can’t see the source until we run the camera.

FAQs - Chimney Repair in Paramus
Yes, and it’s one of the most common hidden problems we find in Paramus’s attached and semi-attached mid-century homes. When your neighbor’s high-efficiency gas appliance vents through a flue in the same masonry chase as your fireplace, the under-temperature exhaust can migrate through porous party-wall brick or open gaps at the smoke chamber, introducing moisture and acidic deposits into your flue. We identify this with a Level 2 camera inspection that traces both flues from top to bottom. If we find cross-contamination, we seal the separation and install a properly sized liner for your fireplace. Call (973) 604-2986 to schedule - estimates are free.
That’s efflorescence - mineral salts left behind when water moves through the masonry and evaporates at the surface. In Paramus, it’s especially common on 1960s single-wythe chimneys because the original mortar has become porous after 50+ years of freeze-thaw cycling. The stain itself is cosmetic, but the water movement causing it is structural. We trace the source - usually a failed crown, open mortar joints, or deteriorated flashing - and repair it before the water causes spalling or interior damage. Call (973) 604-2986 for an inspection - estimates are free.
No, and in Paramus it’s often a sign that an adjacent abandoned flue is shedding spalled tile or mortar onto the smoke chamber ledge above your fireplace. The two-flue chases built here in the 1960s and 70s are reaching the age where clay tiles crack and mortar between flues fails. That debris has to go somewhere, and gravity pulls it down into the active flue. We run a camera to confirm the source and show you exactly what’s happening. Call (973) 604-2986 - estimates are free.
A few cracked tiles in an otherwise sound liner can sometimes be addressed with HeatShield resurfacing, a ceramic repair that seals minor damage without full liner replacement. But “a few” is a judgment call that requires seeing the full flue with a camera. In Paramus, we often find that cracked tiles are the visible symptom of deeper deterioration from acidic condensation in under-fired gas flues. We give you the photos, explain what we see, and tell you honestly whether repair or replacement is the right call. Nothing is recommended without camera evidence you can see for yourself. Call (973) 604-2986 - estimates are free.
Paramus’s concentrated stock of 50-70-year-old chimneys requires more extensive repair on average than newer construction. A 1990s home in Washington Township likely has a factory-built metal chimney with replaceable components; a 1965 Paramus colonial has a single-wythe brick chase with original clay tiles, custom-shaped crown, and integrated flashing that must be carefully disassembled and rebuilt. The labor is more skilled, the materials are more specialized, and the hidden conditions more variable. We price honestly for the work your specific chimney needs, and we show you why. Call (973) 604-2986 for your exact quote - estimates are free.
