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 Danbury Homeowners
Chimney liner and rebuild work in Danbury, CT typically runs from $1,800 for a basic stainless steel liner replacement up to $8,500 or more for a full chimney rebuild, with most projects completed in one to two days. At Hearthstone Chimney Co., we’ve been doing this work in Danbury since 1984, and we don’t start any liner or rebuild job without a Level-2 camera inspection that ends with photos you can see and a plain-English verdict. Call us at (475) 375-9457 - a live person answers, 24 hours a day, every day.
We’ve rebuilt chimneys in the hilly neighborhoods off Shelter Rock Road where freeze-thaw cycles crack mortar joints, and we’ve relined flues in the older Colonials near Main Street where original clay liners have finally given out after eighty years. Danbury’s cold winters and wet springs punish chimney masonry. Water gets in, freezes, expands, and turns small cracks into structural problems. That’s why we document everything with photos, explain what needs attention now versus what can wait, and back every job with our 90-Day Done Right Promise in writing. No arguing. If it’s not right, we come back.
Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, Gelco, and other trusted brands. Most liner and rebuild jobs in Danbury are completed in a single visit, with no-hassle upfront pricing - the number on the estimate is the number on the invoice.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue pipe inserted inside your existing chimney to contain combustion gases and protect the masonry from heat and corrosion. In Danbury, we install these most often in homes with oil or gas heating systems where the original clay liner has cracked or deteriorated, or where a new high-efficiency appliance requires a properly sized flue. Our stainless steel liners use DuraFlex and Olympia Chimney products, professionally measured and cut on-site for an exact fit. We pull a camera through after installation to verify the seal, and we show you the footage.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that can navigate offset flues, chimney bends, and other irregularities that rigid pipe cannot follow. We use flexible liners frequently in Danbury’s older homes - the 1920s Cape Cods near Lake Kenosia and the converted barns out toward Bethel - where chimneys were built before modern standards and don’t run straight. DuraFlex flexible liners allow us to line a flue without dismantling interior walls or exterior masonry. The installation takes a few hours in most cases, and we pressure-test every joint before we leave.
Liner Replacement
Liner replacement becomes necessary when your existing liner - whether clay, metal, or cast-in-place - has failed to the point that repair is no longer safe or cost-effective. In Danbury, we see this most often after chimney fires, which can warp stainless steel or shatter clay tile, and after decades of acidic condensation from modern appliances that eat away at mortar joints. We remove the damaged liner, inspect the surrounding masonry with our camera, and install a new liner sized precisely for your appliance. Every replacement includes a written report with photos, the 90-Day Done Right Promise, and documentation for your insurance or home sale.
Partial Rebuild
A partial rebuild addresses specific sections of chimney damage without replacing the entire structure. In Danbury, we commonly rebuild the top few feet above the roofline where exposure is worst, or we rebuild a single deteriorated wall while preserving sound masonry elsewhere. The homes near Rogers Park with their exposed ridgelines take a beating from wind-driven rain. We’ve rebuilt crowns and upper courses there where the original mortar had turned to sand. We match existing brick and mortar color where possible, and we always install proper flashing and a protective crown to prevent repeat damage.
Full Chimney Rebuild
A full chimney rebuild is required when the structure has deteriorated beyond localized repair - extensive spalling brick, shifted or leaning courses, or internal collapse of multiple flue walls. We’ve done full rebuilds on Danbury homes near the Still River where water infiltration went unaddressed for years, and on properties where earthquakes or vehicle impacts caused structural failure. Our rebuilds use new brick or stone, proper footings, stainless steel liners, and code-compliant clearances. We pull permits through the City of Danbury Building Department, coordinate inspections, and leave you with a chimney that will outlast your mortgage. The 90-Day Done Right Promise applies in full.
Liner Repair
Liner repair is appropriate when damage is limited - a few cracked clay tiles, a small gap at a joint, or early-stage corrosion in a metal liner. In Danbury, we often repair liners in homes where the problem was caught during a routine inspection before it became an emergency. HeatShield cerfractory sealant allows us to smooth and seal clay flue tiles without full replacement, restoring proper draft and protecting the masonry. We only recommend repair when we can document that the liner is structurally sound overall; if the camera shows widespread failure, we’ll tell you plainly that replacement is the wiser investment.

Brands We Service for Chimney Liner & Rebuild
We’ve worked with DuraFlex liners since they first came on the market, and we’ve installed hundreds of their flexible and rigid stainless steel systems in Danbury-area homes. Their corrugated design handles offsets that would stump lesser products, and their lifetime warranty aligns with our own 90-Day Done Right Promise - we both expect the work to last. We stock common DuraFlex diameters and fittings on our trucks, so most installations don’t wait on parts.
HeatShield’s cerfractory sealant is our go-to for liner repair and resurfacing. We’ve restored dozens of clay flue tiles in Danbury with this product, particularly in historic homes where the original liner is sound but the surface has eroded. The material cures to a ceramic finish that withstands temperatures above 2,900 degrees. We also work regularly with Gelco and Copperfield components for caps, dampers, and specialty fittings. Whether you have one of these brands or something else entirely, we’ve likely seen it before. If we haven’t, we’ll research it and get it right.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick means water is moving through the masonry and carrying salts to the surface. In Danbury’s climate, this freeze-thaw cycle accelerates deterioration. We’ve seen efflorescence progress to spalling brick in a single winter on chimneys without caps or proper crowns. The liner may already be compromised.
- Bits of clay tile in your fireplace or cleanout indicate that the original flue liner is breaking apart. Those pieces fell from inside the chimney, and more will follow. A damaged clay liner allows heat and combustion gases to reach combustible framing, and it can block the flue entirely. This is not a maintenance item you defer.
- Rust stains on the chimney face or damper mean moisture is combining with metal components, and often that the liner itself is rusting through. Stainless steel liners resist corrosion, but they fail eventually if water gets in through a cracked crown or missing cap. We find this frequently on Danbury chimneys after ice dam seasons.
- Smoke or odors entering your home during heating season suggest a breach in the liner or a blockage that is forcing exhaust into living space. Carbon monoxide is odorless and deadly. If you’re experiencing this, stop using the appliance and call us. We’ll prioritize the inspection.
- Visible leaning, cracking, or separation of the chimney from the house indicates structural failure that threatens the entire assembly. In Danbury’s hilly terrain, we’ve seen chimneys settle differentially as foundations shift on cut-and-fill lots. A leaning chimney can collapse without warning, and it almost certainly has internal damage that compromises the liner.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule and confirm. Call (475) 375-9457 and a live person will answer, any hour of any day. We’ll ask about your chimney’s age, the symptoms you’ve noticed, and what appliances vent through it. We’ll schedule a Level-2 inspection at your convenience and send a confirmation. No deposit required.
- 2
Level-2 camera inspection. Our technician arrives in a marked vehicle, in uniform, and begins with a visual assessment of the exterior, crown, cap, and flashing. We then run a high-resolution camera up the flue, recording every inch. You see the footage in real time. We document cracks, gaps, corrosion, blockage, and creosote buildup. The inspection produces a written report with photos and a plain-English verdict.
- 3
Plain-English recommendation and upfront pricing. We explain what we found, what it means for safety and function, and what options exist - repair, reline, partial rebuild, or full rebuild. We show you the photos that support each recommendation. You’ll receive a written estimate with a single number, not a range designed to rise later. The price includes all materials, labor, permits, and cleanup.
- 4
Professional installation or rebuild. Our technicians work with professional-grade materials from DuraFlex, HeatShield, Gelco, and other trusted brands. For liner work, we protect your home with drop cloths, use proper venting and vacuum equipment, and verify every joint. For rebuilds, we match existing masonry, install proper flashing and crowns, and coordinate city inspections. Most jobs finish in one visit; full rebuilds typically take two.
- 5
Final inspection, documentation, and guarantee. We run the camera again after liner installation to verify the seal and proper draft. We photograph the completed rebuild from multiple angles. You receive all documentation, including photos, the written 90-Day Done Right Promise, and maintenance guidance. If anything isn’t right, we come back. No paperwork to file, no argument to have.
How Much Does Chimney Liner & Rebuild Cost in Danbury?
Chimney liner and rebuild costs in Danbury depend on the scope, materials, and access. Here are the ranges we see most often:
- HeatShield liner repair/resurfacing: $1,200-$2,400
- Stainless steel liner replacement (straight flue, standard access): $1,800-$3,200
- Flexible liner installation (with offsets or bends): $2,400-$4,000
- Partial rebuild (crown and upper courses): $3,500-$6,500
- Full chimney rebuild with new liner: $6,500-$12,000+
Several factors push costs higher or lower. A straight flue on a single-story ranch in Danbury costs less than a three-story Colonial with multiple offsets near the ridge line. The condition of existing masonry matters - if we open the chimney and find hidden water damage or code violations from prior work, the scope expands. We always find this during inspection, not mid-job, and we discuss it with you before proceeding.
The best way to avoid overpaying is to get a camera inspection from a company that shows you the evidence. We’ve seen Danbury homeowners quoted thousands for full rebuilds when a $1,500 liner repair would have sufficed, and we’ve seen cheap liner jobs that failed in two years because the installer sized the flue wrong or used builder-grade materials. Our estimates are free, our pricing is upfront, and we guarantee our work in writing.
Current offers include $50 off any repair over $250, a free second opinion on any written estimate, and a permanent 5% senior and veteran discount. Call (475) 375-9457 for your exact quote.
