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.

AfterFast, Reliable Chimney Liner & Rebuild Across Plainview
A stainless steel chimney liner installed in a Plainview ranch or split-level typically runs $2,800-$4,200, while a partial chimney rebuild starts around $3,500 and can reach $8,000 depending on how far the freeze-thaw damage has traveled. Most liner jobs and smaller rebuilds are completed in a single visit. If your Plainview home was converted from oil to gas in the 80s or 90s, there’s a strong chance your clay flue tiles are oversized for the appliance and degraded by years of acidic condensation - we’ll confirm it with a camera and show you the photos before recommending any work. Call (934) 348-4832 to schedule a Level 2 inspection; estimates are free.

Why Hearthstone Chimney Co. Is Plainview’s Preferred Chimney Liner & Rebuild Company
Plainview’s chimneys are aging together. Built during Long Island’s postwar suburban boom from roughly 1950 to 1972, most are now 60 to 70 years old and hitting the same deterioration curve at the same time. We’ve watched this unfold here since 1984. That continuity matters. A company that plans to be answering the phone in thirty years does not cut corners on mortar mixes or liner gauges.
Our reputation in Plainview rests on documentation. Every Level 2 inspection ends with photos you can see and a plain-English verdict - no jargon, no pressure. If the liner is cracked, we show you the crack. If the mortar joints are sound, we say so, and the job can wait. The 90-Day Done Right Promise backs every liner and rebuild job in writing: if it’s not right, we make it right, no paperwork, no arguing. Background-checked, uniformed technicians arrive when scheduled, and most liner replacements and partial rebuilds finish in one day. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Our Chimney Liner & Rebuild Services in Plainview
Stainless Steel Liner Installation
For Plainview’s converted gas systems, a correctly sized stainless steel liner is usually the fix. Those original 8-inch clay flue tiles were built for oil furnaces pumping hot, dry exhaust. A modern 4-inch gas appliance running through that oversized channel produces cool, wet exhaust that condenses on the tile walls and eats the joints from inside. We install rigid or flexible stainless liners from DuraFlex and Olympia Chimney, sized precisely to the appliance. On a ranch near Woodbury Road last winter, we dropped a 5-inch flexible stainless liner through a 1961 chimney with eroded tile joints and capped it with a Gelco cap - the draft improved immediately, and the condensation problem stopped.
Flexible Liner for Tight Flues
Plainview’s low-pitch ranch roofs don’t always give us straight shots. When offsets or tight smoke chambers block a rigid liner, we use a flexible stainless liner that navigates the bends without losing diameter. The material is the same high-grade alloy - just formed into a corrugated tube that bends without kinking. We see this need often in the split-levels near South Oyster Bay Road, where the chimney chase angles around a second-floor overhang. Flexible liner installation in Plainview typically runs $2,400-$3,800.
Liner Replacement
Sometimes the clay tiles are too far gone for anything else. On a split-level off Old Country Road, our tech opened a 1963 clay-tile flue that had been converted from oil to gas decades earlier and found the tile joints eaten through by years of acidic condensation from the oversized-for-the-appliance flue. We ran a Level 2 inspection, confirmed the cracked liner with a camera, and installed a correctly sized stainless steel liner with a new chimney cap and damper to match the modern gas appliance - then walked the homeowner through burning practice to keep draft and creosote in check. Liner replacement in Plainview runs $2,800-$4,500 depending on height, diameter, and whether the smoke chamber needs parging.
Partial Chimney Rebuild
Nassau County’s hard freeze-thaw cycles destroy soft-set mortar joints. Plainview’s mid-century chimneys were built with single-wythe brick and mortar that was never meant to survive seventy winters. When spalling bricks and eroded joints extend beyond the top few courses, a partial rebuild becomes necessary. We dismantle to sound masonry, rebuild with matching brick and proper weatherstruck joints, and integrate a new liner system so the flue and structure fail on different schedules. Partial rebuilds in Plainview start at $3,500 and typically reach $6,500 for a standard ranch chimney.

Trusted Brands We Service in Plainview

Keeping inventory close means faster turnaround for Plainview homeowners. When we find a cracked liner during your annual cleaning, we can often return within the week with the correct diameter and length already on the truck, rather than ordering and waiting.
Common Chimney Liner & Rebuild Problems We See in Plainview Homes
- Oversized clay flues serving converted gas appliances. Plainview’s 1950s-70s ranch and split-level chimneys were originally sized for oil-fired furnaces, so the cheap oil-to-gas conversions of the 80s and 90s left oversized 8-inch clay flue tiles serving modern 4-inch gas appliances - a chronic condensation mismatch that degrades tile joints from the inside and turns routine annual cleanings into liner-integrity work.
- Freeze-thaw mortar destruction. Nassau County’s position on Long Island delivers hard freeze-thaw cycles each winter that are especially destructive to the aging, soft-set mortar joints common in Plainview’s mid-century masonry chimneys, accelerating spalling and joint erosion year over year.
- Salt-air corrosion of metal components. The proximity to Long Island Sound and the South Shore means periodic salt-laden air that corrodes chimney caps, dampers, and metal flashing faster than inland locations, letting water into the flue and accelerating deterioration.
- Hidden liner cracks on low-visibility roofs. Plainview’s tight, ranch-style roof pitches create access challenges and mean liner cracks often go unnoticed until a cleaning inspection reveals them - sometimes after years of slow water intrusion and creosote glazing.

What moves the number? Height matters - a two-story split-level costs more than a single-story ranch. Access matters - steep pitches or tight side yards add labor. The condition of the existing clay tile matters - if we have to break out collapsed sections before inserting the liner, that adds time. And the appliance count matters: a furnace and water heater sharing a flue need a correctly sized liner for combined BTU load, not just one appliance. We price every job after inspection, not before. The estimate is free, and the number we give is the number on the bill. Call (934) 348-4832 for yours.

FAQs - Chimney Liner & Rebuild in Plainview
Probably, yes. The 8-inch clay flue tiles in your 1960s ranch were sized for an oil furnace’s hot, dry exhaust. Your modern 4-inch gas appliance produces cooler, wetter exhaust that condenses inside that oversized flue, and years of that acidic condensation have likely dissolved the tile joints. We see this on almost every converted Plainview ranch we inspect. Call (934) 348-4832 and we’ll run a camera to confirm - the inspection runs $250-$350, estimates are free.
Every season, without exception, and sometimes mid-season if you’re burning green or soft wood. Wood stoves as primary heat in Plainview’s older ranches load creosote faster than occasional fireplace use - the flue runs cooler, the draft is steadier, and the buildup is heavier. We recommend a professional sweep before lighting the first fire each fall, and a Level 2 inspection every two years to catch liner degradation before it becomes a hazard. Call (934) 348-4832 to book your pre-season sweep.
The crown concrete was never designed to survive seventy Nassau County winters. Hard freeze-thaw cycles attack the porous surface, and salt-laden air from Long Island Sound accelerates the breakdown. Once cracks open, water enters the chimney body, freezes, expands, and widens the damage. A proper crown repair with poured concrete or a Gelco crown seal stops the cycle. In Plainview, we also see crowns that were originally sloped wrong - flat crowns pool water and fail faster. We’ll show you the pitch on camera and fix it right.
A Level 2 inspection means we run a high-resolution camera up the full length of your flue and document every crack, joint gap, and glaze deposit. You see the same footage we see, in real time or recorded. For Plainview’s converted gas systems, we pay special attention to tile joint erosion at the flue’s lower third - that’s where acidic condensation pools. The inspection takes 45-90 minutes and ends with a plain-English verdict: repair now, monitor, or no action needed. No recommendation without photo evidence you can see yourself. Call (934) 348-4832 to schedule.
Often, yes. If the clay tiles are cracked but the surrounding masonry is sound, we can install a stainless steel liner inside the existing flue without disturbing the chimney structure. This is the standard approach for Plainview split-levels where the brickwork is still solid but the flue has failed from condensation or age. We only recommend a partial or full rebuild when the mortar joints are eroded or spalling bricks threaten the chimney’s structural integrity. The camera inspection tells us which path is right for your chimney. Call (934) 348-4832 for a free estimate.
