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 Yardville
Chimney liner installation and chimney rebuilds in Yardville typically cost between $1,800 and $5,500 depending on scope, and most projects are completed in a single visit with materials from DuraFlex, HeatShield, and Gelco. If your Yardville home still runs a gas furnace through an original oil-era clay flue tile, the liner is almost certainly oversized and running cold - acidic condensate is likely eating the mortar from the inside while you read this. Call (856) 388-5580 to book a Level 2 camera inspection; estimates are free, and you’ll see the footage yourself before we recommend anything.
We’ve been dispatching crews to Yardville from our coordination office for over 42 years. We know the post-WWII Cape Cods off Route 156, the ranch homes near Yardville-Hamilton Square Road, and the split-levels tucked behind the Hamilton Marketplace. These houses were built with single-wythe brick chimneys and clay flue tiles sized for oil heat, and most haven’t been properly inspected since the fuel switch. That’s not a sales pitch. It’s what our cameras show, week after week.
Why Hearthstone Chimney Co. Is Yardville’s Preferred Chimney Liner & Rebuild Company
Our reputation in Yardville was built one chimney at a time - no billboards, no coupon packs, just homeowners telling their neighbors that we showed them the problem before we quoted a fix. We carry a strong local reputation across Mercer County, with homeowners in Yardville specifically mentioning our camera inspections and plain-English verdicts in their feedback.
When you call (856) 388-5580, a live person answers - 24 hours a day, 7 days a week. No voicemail, no callback queue. We coordinate scheduling from our New York City office, but our background-checked, uniformed technicians live and work in the Central Jersey area, so Yardville appointments are typically available within a few business days. Most liner replacements and partial rebuilds are completed in a single visit, with no-hassle upfront pricing: the number on the estimate is the number on the invoice.
We know Yardville’s specific failure patterns because we’ve documented them. The oil-to-gas conversions that started in the 1980s and continued through the 2000s left hundreds of local chimneys with flues that are technically “working” but fundamentally wrong for the appliance attached. We don’t guess. We run the camera, we show you the SD card, and we explain what you’re looking at in plain English.
Our Chimney Liner & Rebuild Services in Yardville
Flexible Liner Installation
Flexible stainless steel liners are our most common recommendation for Yardville’s mid-century chimneys, and for good reason. The masonry flues in these 1940s-1960s homes are rarely straight - decades of settling, freeze-thaw damage, and partial rebuilds have left offsets and ledges that a rigid liner simply won’t navigate. We use DuraFlex and Olympia Chimney flexible liners, sized precisely to the appliance’s BTU output and venting requirements. In a typical Yardville ranch or Cape Cod, we’ll insulate the liner, properly seal the top and bottom connections, and leave you with a system that drafts correctly and meets NFPA 211 standards. Most flexible liner jobs in Yardville run $2,200-$3,800.
Liner Replacement
When clay flue tiles are cracked, collapsed, or eroded by years of acidic condensate, patching isn’t an option - the liner needs to come out and a new one needs to go in. This is the scenario we find most often in Yardville homes that converted from oil to gas without updating the chimney. The oversized flue runs too cold, water vapor condenses on the tile walls, and the resulting sulfuric acid slowly dissolves the mortar joints from the inside out. Our Chimney Liner & Rebuild team removes the damaged tiles, cleans the flue, and installs a correctly sized replacement liner with proper insulation and termination. A full liner replacement in Yardville typically costs $2,800-$4,500 depending on flue height and accessibility.
Partial Rebuild
Not every damaged Yardville chimney needs Chimney Repair in Yardville to mean a full tear-down to the roofline. When the upper courses of brick have spalled from freeze-thaw cycles but the lower structure and firebox are sound, we rebuild from the damaged point upward - replacing the crown, repointing mortar joints, and installing proper flashing. This is common on Yardville homes where the crown cracked years ago and water has been working its way down through the masonry ever since. A partial rebuild in Yardville generally runs $1,800-$3,200, compared to $4,500-$7,500 for a full stack rebuild. We only recommend what the camera and our inspection show; if the lower flue is intact, we’ll tell you.
Stainless Steel Liner
For straight, structurally sound flues in newer Yardville construction or homes that have already had partial rebuilds, rigid stainless steel liners offer maximum durability and the smoothest interior surface for optimal draft. We stock Copperfield and Gelco rigid liners for these applications, typically in 316Ti alloy for oil and solid fuel, or 304 for gas-only installations. Rigid liner jobs in Yardville start around $2,500 and top out near $4,000 for multi-flue configurations.

Trusted Brands We Service in Yardville
We don’t use builder-grade substitutes, and we don’t special-order parts that keep you waiting. Our trucks carry DuraFlex flexible liners, HeatShield cerfractory sealant for smoke chamber parging, and Gelco stainless components - the same materials we specify for our own Chimney Liner & Rebuild in Yardville projects. When a Yardville homeowner needs a partial rebuild, we source matching brick and proper Type N or Type S mortar rather than patching with whatever’s on the shelf. The result is a repair that blends with the existing chimney and lasts. Most jobs don’t require a return trip for parts because our technicians arrive with what the inspection indicated they’d need.
Common Chimney Liner & Rebuild Problems We See in Yardville Homes
- Oversized oil-era flues running cold with gas appliances. The 1940s-1960s clay flue tiles in Yardville’s Cape Cods and ranches were designed for oil furnaces that ran 500-600°F flue gases. Today’s high-efficiency gas appliances might exit at 250-350°F - never hot enough to dry the oversized flue, so condensate runs down the walls year-round and quietly dissolves mortar joints the homeowner can’t see from below.
- Freeze-thaw spalling on single-wythe brick chimneys. Yardville sits in Mercer County’s Delaware Valley zone, where winters deliver repeated freeze-thaw cycles rather than prolonged deep freezes. Water infiltrates hairline crown and mortar cracks, expands on freezing, and progressively fractures the masonry - often mistaken for “just old brick” until a camera inspection reveals the flue tile behind it is cracked too.
- Gas furnace retrofits without proper liner or smoke chamber seals. When an old oil-era firebox gets tapped by a gas furnace without a correctly sized liner, flue gases and condensate migrate into the surrounding masonry. We’ve found damper frames rotted from behind, smoke chambers eroded to bare brick, and hidden voids that would never show up on a Level 1 visual inspection.
- Original clay tiles cracked from decades of thermal shock. The clay flue liners in Yardville’s 55-80-year-old chimneys were never designed for the rapid on-off cycling of modern gas appliances. Repeated expansion and contraction causes vertical cracking, and once a tile is cracked, it can’t be repaired - only replaced.

FAQs - Chimney Liner & Rebuild in Yardville
Not automatically, but in our experience across Yardville’s mid-century housing stock, the answer is usually yes once we run the camera. The flue tile itself may look intact from the firebox, but the combination of an oversized flue and lower flue temperatures from gas creates acidic condensate that erodes mortar joints from the inside. We pulled up to a 1958 ranch off Yardville-Hamilton Square Road where the homeowner had been running a gas furnace into the original oil-era flue for two decades and had never once had it inspected. Our camera showed third-degree creosote at the firebox throat and clay tiles cracked clean through two feet above the damper with mortar spalling at the crown - none of it visible from below. We insulated and dropped a correctly sized flexible stainless liner, HeatShield-sealed the smoke chamber, rebuilt the crown, and left the homeowner with the SD card so they could watch the same footage we did. Call (856) 388-5580 for a free inspection; we’ll show you exactly what your flue looks like.
A Level 2 inspection uses a video camera to examine the entire flue interior, the smoke chamber, and accessible portions of the exterior masonry - areas completely hidden in a Level 1 visual check. On Yardville’s 55-80-year-old chimneys, this is where we find cracked flue tiles, eroded mortar joints, condensate damage, and gaps between the flue liner and chimney structure that a flashlight from below simply cannot reveal. The Level 2 inspection ends with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. Call (856) 388-5580 to schedule; the inspection runs $250-$350 and is free with any booked repair.
Yardville’s Delaware Valley climate is actually harder on chimneys than a single deep freeze would be. Our winters deliver repeated freeze-thaw cycles - temperatures swing above and below 32°F dozens of times per season. Water infiltrates hairline cracks in the crown or mortar joints, expands slightly on each freeze, and progressively fractures the masonry. By March, what started as a hairline crack is a spalled face brick and a compromised flue liner. The damage accelerates once the outer wythe loses its protective surface. A partial rebuild with our Chimney Cap & Crown in Yardville services for proper crown drainage and repointed joints stops the cycle. Call (856) 388-5580 and we’ll assess whether your chimney needs rebuilding or if targeted repairs will suffice.
Yes, and we often do. When the lower flue and firebox are structurally sound, our Fireplace Services in Yardville include partial rebuilds from the damaged point upward - the right repair - and significantly less expensive than tearing down to the foundation. We see this scenario frequently in Yardville, where the upper courses and crown have taken the brunt of freeze-thaw damage but the lower chimney and liner are intact. Our camera inspection confirms the lower flue condition before we recommend anything. A partial rebuild in Yardville typically runs $1,800-$3,200 versus $4,500-$7,500 for full reconstruction. Call (856) 388-5580 for an exact assessment of your chimney.
We install DuraFlex and Olympia Chimney flexible liners, Gelco and Copperfield rigid liners, and use HeatShield cerfractory sealant for smoke chamber repairs. The brand matters because these are professional-grade products with documented testing to UL 1777 and proper alloy specifications for your fuel type - not the thin-gauge generic liners sold online. A DuraFlex 316Ti flexible liner, properly insulated and sized, will outlast the appliance it’s venting. We don’t substitute brands without explaining why, and we don’t install materials we wouldn’t use on our own homes. Call (856) 388-5580 to discuss which liner suits your Yardville chimney’s condition and your heating setup.
