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.

AfterTrusted Chimney Liner & Rebuild for Trenton Homeowners
A damaged chimney liner or deteriorating masonry in Trenton can let dangerous gases seep into your living space and put your home at real risk. Most liner replacements and partial rebuilds in the Trenton area run between $1,800 and $4,500 depending on height, access, and materials, and our crew at Hearthstone Chimney Co. completes most jobs in a single visit. We’ve been serving Trenton and Mercer County since 1984, and Russell Haines has built this company on one principle: show the homeowner exactly what’s wrong, fix it with materials that last, and stand behind the work in writing.
We’ve rebuilt chimneys in the Mill Hill neighborhood after freeze-thaw damage cracked the brick, replaced corroded liners in homes near the Delaware River where moisture accelerates deterioration, and relined flues in Trenton’s older stock - the pre-war colonials and 1920s twins where original terra cotta has finally given out after nearly a century - through our Chimney Liner & Rebuild in Trenton. Every job starts with a Level-2 camera inspection. You see the photos. We explain what they mean in plain English. Then we give you upfront pricing with no surprises on the bill. Call (856) 519-0832 - a live person answers, 24 hours a day.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is the permanent solution for a flue that’s cracked, corroded, or improperly sized for your heating appliance. In Trenton, we install DuraFlex and Olympia Chimney stainless steel liners for wood-burning fireplaces, gas inserts, and oil-fired systems, each one measured and cut to fit your exact flue dimensions. Our crew pulls the liner from the top, connects it to your appliance with a proper collar and insulation pack where code requires, and pressure-tests the joints before we call the job complete. Most stainless steel liner installations in Trenton finish in one day.
Flexible Liner
Flexible liners solve the problem of offset flues, chimney shifts, and the irregular clay liners common in Trenton’s older homes, particularly in the Chambersburg and Battle Monument neighborhoods where settling has created offsets no rigid pipe can navigate. We use DuraFlex flexible stainless steel for these jobs, feeding the liner down from the roof and expanding it to seat against the flue walls with an insulation blanket that maintains proper draft temperature. Flexible liners cost less than a full rigid system and adapt to chimneys that would otherwise need partial rebuilding to straighten the flue.
Liner Replacement
When your existing liner has failed - cracked terra cotta, corroded aluminum, or a previous installation done with the wrong material - complete replacement is the only safe option. We remove the damaged liner where accessible, or in some Trenton homes with tight clearances, we slide the new liner inside the old and fill the annular space with insulating mix. Every replacement includes a new top plate, rain cap from Famco or Copperfield, and a written 90-Day Done Right Promise. We’ve replaced liners in homes from Yardville to North Hanover, and we know the local code variations that affect installation method.
Partial Rebuild
A partial rebuild addresses the section of chimney that’s failed while preserving sound masonry below, typically the top four to six courses of brick, the crown, or one flank of a chimney where water has penetrated and spalled the face. In Trenton’s climate, with freeze-thaw cycles that start in late October and run through March, we’ve learned to spot the early signs: mortar that’s turned to powder, brick faces that flake off in layers, and crowns cracked like a dried riverbed. We bring the same expertise to our Chimney Liner & Rebuild in Bordentown. Our partial rebuilds use matching brick where possible, proper crown slope with drip edge, and a through-flashing where the chimney meets the roofline.
Full Chimney Rebuild
When structural integrity is compromised - leaning stack, widespread spalling, or internal collapse of multiple flue liners - a full rebuild is the only responsible course. We’ve done full rebuilds on Trenton homes in the Cadwalader Heights historic district, working with homeowners to match original brick and maintain the architectural character while building to modern standards. A full rebuild includes new footings where required by code, reinforced block or brick construction, proper flue sizing for your appliance, and a poured concrete crown with expansion joints. These jobs typically take three to five days, and we protect your property with scaffolding mats and daily cleanup.
Liner Repair
Not every liner problem requires full replacement. For minor cracks and gaps in otherwise sound terra cotta, we apply HeatShield cerfractory sealant, a refractory compound that fills voids and restores the flue’s smooth, gas-tight surface. This is a cost-effective option for Trenton homeowners whose liners show isolated damage but haven’t suffered structural failure. The process involves a thorough cleaning, video inspection to map the damage, application of the HeatShield material with a custom-forming plug, and a final video verification that the repair is complete. Liner repair costs a fraction of replacement and extends serviceable life when conditions allow.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of DuraFlex liner systems across Mercer County, from the flexible multi-ply models for offset flues to rigid sections for straight runs in new construction. DuraFlex builds their liners with 316Ti stainless steel and offers lifetime warranties on many models, and we stock the full range of collars, top plates, and termination caps so we’re not waiting on parts when your job is scheduled.
HeatShield’s cerfractory resurfacing system is our go-to for liner repair jobs where the terra cotta is cracked but structurally sound - we’ve applied it in homes near the Trenton Battle Monument and in the Hiltonia section with excellent results. For caps, dampers, and termination hardware, we work with Famco and Copperfield, both American manufacturers whose parts fit precisely and hold up to our freeze-thaw cycles. Whether your chimney has one of these brands or another make entirely, our technicians carry the tools and knowledge to service it correctly.
Signs You Need Chimney Liner & Rebuild Right Now
- White efflorescence or spalling brick on the exterior. That white powder is mineral salts pushed out by moisture migrating through the masonry, and it means water is getting in faster than it can evaporate. In Trenton’s clay-heavy soils, freeze-thaw damage accelerates once this starts, turning small cracks into structural problems within a season or two.
- Flakes of terra cotta in the firebox or cleanout. Those shards are pieces of your liner falling away, and each one represents a gap where hot gases or sparks can reach combustible framing. We’ve found this in Trenton homes where the original liner dated to the 1940s or earlier, and it’s a condition that only worsens with use.
- Smoke or odors entering the house during operation. A liner that’s cracked near a smoke chamber wall or thimble connection can leak combustion gases into wall cavities and living spaces. Carbon monoxide is odorless and invisible, so any smoke smell is a warning that the flue’s integrity is compromised.
- Visible cracks in the chimney crown or missing mortar joints. The crown is your chimney’s umbrella, and once it fails, water runs directly into the core of the masonry. We’ve rebuilt crowns in Trenton that were poured flat or without expansion joints, both of which guarantee premature failure in our climate.
- Your appliance has changed but the liner hasn’t. Switching from oil to gas, installing a wood stove insert, or upgrading to a high-efficiency furnace often requires a different liner size or material. An improperly matched liner causes poor draft, creosote buildup, or condensation damage that destroys the flue from the inside.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule and arrival. Call (856) 519-0832 and a live person will book your appointment - no voicemail, no callback queue. Our technician arrives in a marked vehicle, in uniform, with background-checked credentials you can verify. We lay protective coverings from the door to the work area.
- 2
Level-2 camera inspection. We run a high-resolution video camera through the full length of your flue, documenting cracks, gaps, creosote buildup, and structural condition. You watch the feed in real time if you’re present, or we provide the video file and still photos with your written report. This inspection is the foundation of every recommendation we make.
- 3
Plain-English verdict and upfront pricing. Russell Haines insists on this: no jargon, no pressure, no recommendations without evidence you can see. We explain what the camera found, what it means for safety and function, and what options exist - repair, reline, partial rebuild, or full rebuild. The price we quote is the price on the invoice. Period.
- 4
Professional installation with documented materials. Our crew uses DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, or Copperfield materials as specified - never builder-grade substitutes. For rebuilds, we match existing brick where possible and always install proper crowns with slope, drip edge, and expansion joints. Most liner jobs complete in one visit; rebuilds are scheduled with clear timelines.
- 5
Final inspection, cleanup, and written guarantee. We run the camera again to verify the repair, test draft and appliance function, and leave your home cleaner than we found it. You receive a written report with photos, the 90-Day Done Right Promise, and our direct line for any follow-up. If it’s not right, we make it right - no paperwork, no arguing.
How Much Does Chimney Liner & Rebuild Cost in Trenton?
Chimney liner and rebuild costs in Trenton depend on height, access, materials, and the extent of masonry damage - learn more about how much Chimney Liner & Rebuild costs. Here’s what typical jobs run in our market:
| Service | Typical Range in Trenton | What Affects Price |
|---|---|---|
| HeatShield liner repair | $1,200 - $2,400 | Flue length, number of cracks, accessibility |
| Flexible stainless steel liner | $1,800 - $3,200 | Flue diameter, insulation requirements, termination type |
| Rigid stainless steel liner | $2,200 - $4,000 | Number of flues, offsets, appliance connection complexity |
| Partial rebuild (top 4-6 feet) | $2,500 - $5,500 | Brick matching, crown construction, scaffolding needs |
| Full chimney rebuild | $6,500 - $14,000 | Height, footing condition, historic preservation requirements, liner system |
Several factors push prices toward the higher end. Chimneys over two stories require scaffolding or boom equipment. Historic districts like Mill Hill or Cadwalader Heights may need brick matching that extends timeline and material cost. Interior flues with multiple bends or offset clay liners take more labor to navigate. And if the crown has been leaking for years, the damage often extends deeper than surface inspection reveals - we document this with camera evidence before work begins.
The best way to avoid overpaying is to get a second opinion on any written estimate over $2,500. Hearthstone Chimney Co. offers a free second opinion on any competitor’s written quote - bring us the paperwork and we’ll review it honestly, even if you don’t hire us. We also provide $50 off any repair over $250 and a permanent 5% senior and veteran discount. Every estimate is free, includes the camera inspection and photo report, and comes with no obligation.

A live person answers our phones 24 hours a day, 7 days a week, and we’ll assess urgency over the phone and dispatch accordingly. For non-emergency work, we schedule within a week in most cases.
Every job is backed by our 90-Day Done Right Promise in writing - if anything about our work isn’t right, we return and make it right with no paperwork and no arguing. Many of the liner systems we install carry manufacturer warranties of 10 years to lifetime, and we register these on your behalf.

Clear a path from your entry door to the fireplace or appliance, remove fragile items from the mantel and hearth area, and ensure pets are secured in another room. For exterior work, trim back branches that touch or overhang the chimney, and move vehicles from the driveway to give our crew equipment access. We’ll cover floors and furniture with protective materials, and we clean thoroughly before leaving - your preparation is minimal.
