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 Woburn Homeowners
A Chimney Liner & Rebuild - Woburn typically costs between $2,800 for a stainless steel liner replacement and $15,000 or more for a full chimney rebuild, with most liner jobs completed in a single day. Hearthstone Chimney Co. has been serving Woburn and surrounding communities since 1984, and our Level-2 camera inspections give you photos you can see and a plain-English verdict before any work begins. Call (781) 404-3793 to speak with a live person, 24 hours a day, 7 days a week.
We’ve rebuilt chimneys in Woburn’s older neighborhoods like the Mishawum area and newer developments near Interstate 93, and we’ve learned what this climate does to masonry. Freeze-thaw cycles in Middlesex County are hard on brick and mortar. Water gets in, expands, and turns small cracks into structural problems. A damaged liner or crumbling chimney isn’t just inefficient. It’s a path for carbon monoxide to enter your living space and a fire hazard that gets worse every season you wait. Our 90-Day Done Right Promise means if it’s not right, we come back. In writing, no arguing.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a rigid or corrugated metal tube that protects your chimney walls from heat and corrosive flue gases. In Woburn, we install stainless steel liners most often in homes built before 1980 that have unlined brick chimneys or original clay liners that have cracked after decades of heating and cooling. Hearthstone Chimney Co. uses professional-grade DuraFlex stainless steel liners, sized precisely to your appliance’s BTU output, with proper insulation to meet Massachusetts building code and NFPA 211 standards.
Flexible Liner
A flexible liner is a corrugated stainless steel tube that can navigate offsets and bends in chimneys where a rigid liner won’t fit. We recommend flexible liners for Woburn’s Victorian-era homes on Main Street and Pleasant Street, where chimney construction often includes sharp turns that would require expensive masonry alteration with rigid pipe. Our technicians measure with a video camera first, then pull the correctly sized flexible liner from Olympia Chimney with poured insulation for a complete, code-compliant installation.
Liner Replacement
Liner replacement removes a failed or outdated flue liner and installs a new one without rebuilding the surrounding masonry. You’ll need this when your Level-2 inspection shows cracked clay tiles, spalling mortar between tiles, or gaps where combustion gases can leak into chimney walls. In Woburn, we see this most often in homes that switched from oil to gas without updating the liner diameter, a mismatch that causes condensation damage. We document the old liner’s condition with photos, explain why replacement is necessary, and show you the new liner’s installation before we close up.
Partial Rebuild
A partial rebuild restores the damaged section of a chimney, typically from the roofline up, while preserving sound masonry below. This is the right choice when the upper courses of brick have deteriorated from weather exposure but the lower chimney structure and fireplace are solid. Woburn’s proximity to the Mystic Lakes means some neighborhoods see more moisture-driven spalling than inland areas, and we’ve rebuilt chimney crowns and top courses throughout the North Woburn area. We match existing brick color and mortar profile, and we always install a proper concrete crown with positive drainage to protect the new work.
Full Chimney Rebuild
A full chimney rebuild dismantles the existing chimney to the roofline or below and constructs a new one to current code. This becomes necessary when multiple courses are compromised, the chimney leans, or structural integrity has failed beyond repair. In Woburn’s older neighborhoods, we’ve rebuilt chimneys that date to the 1920s, replacing degraded brick with new materials and installing a properly sized stainless steel liner as part of the project. The 90-Day Done Right Promise covers the full rebuild, and we leave the work site cleaner than we found it.
Liner Repair
Liner repair addresses localized damage without full replacement, using techniques like HeatShield cerfractory flue sealant for resurfacing cracked clay tiles or stainless steel sleeves for isolated breaches. Not every cracked liner needs replacement, and we’re plain about when repair is sufficient versus when replacement is the only safe option. Our camera inspection shows you exactly what we’re seeing, and we’ll tell you if the damage can wait a season or needs immediate attention. In Woburn, we’ve saved homeowners thousands with targeted liner repairs when the damage was caught early.

Brands We Service for Chimney Liner & Rebuild
We’ve installed hundreds of DuraFlex stainless steel liners in Woburn-area homes, and we stock the full range of diameters and lengths for same-day completion on most liner jobs. Their corrugated design handles the offsets common in older chimneys, and the 316Ti alloy resists the acidic condensate produced by high-efficiency gas appliances. We also work extensively with Olympia Chimney products, including their ProFlex flexible liner system and proprietary insulation mix that meets the strictest Massachusetts energy code requirements.
Our rebuild crews source masonry materials and chimney caps from Famco and Copperfield, brands we’ve trusted for decades for consistent sizing and weather resistance. Famco’s galvanized and stainless steel chimney caps stand up to Woburn’s coastal-influenced winters without the corrosion we see on big-box hardware store versions. Whether you have DuraFlex, Olympia Chimney, Famco, Copperfield, or any other make, we can help. We don’t limit our service to brands we prefer, and we’ll repair or replace whatever system is in your home using materials that meet or exceed original specifications.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick means water is moving through your chimney masonry, dissolving salts, and depositing them on the surface. In Woburn, this accelerates after wet winters like 2023’s heavy snow season, and it’s often the first visible sign that freeze-thaw damage is compromising your chimney’s structural integrity.
- Flakes of clay or debris in your fireplace or cleanout indicate that your clay tile liner is spalling, cracking, or disintegrating. These pieces are your liner literally falling apart, and they create gaps where creosote can build up on combustible masonry surfaces.
- Smoke or odors entering your home during fireplace use suggests a breach in the liner or a blocked flue that is forcing combustion gases into living spaces. Carbon monoxide is odorless and dangerous, so any smoke intrusion warrants an immediate Level-2 inspection with a camera.
- Visible cracks in the chimney crown or missing mortar between bricks allow water directly into the chimney structure. Woburn’s freeze-thaw cycle turns small cracks into major damage in as little as two or three winters, and crown cracks are the single most common cause of chimney rebuilds we perform.
- A rusted damper or firebox with water staining proves water is traveling down the flue, often because the liner is cracked or the chimney cap is missing or damaged. Left unaddressed, this rust weakens the damper mechanism and can require firebox rebuilds that add significant cost to the project.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule your inspection. Call (781) 404-3793 and a live person will answer, 24 hours a day, 7 days a week. We’ll find a time that works for your schedule, and we’ll confirm our arrival window the day before. No four-hour windows that stretch into evening, and we’ll call if traffic from Route 93 or I-95 delays us.
- 2
Level-2 camera inspection and documentation. Our technician arrives in a marked vehicle, uniformed and background-checked, and begins with a visual assessment followed by a video scan of the entire flue. You’ll see the footage in real time, and we email you the recording with timestamped notes and a plain-English verdict. If the liner is cracked, we measure the exact location and severity. If masonry is compromised, we photograph the damage from roof level and explain what caused it.
- 3
Upfront written estimate with no obligation. We deliver a detailed estimate before any work begins, with line-item pricing for materials and labor. The number on the estimate is the number on the invoice. For liner jobs, we specify the brand, diameter, and insulation R-value. For rebuilds, we note brick type, mortar mix, and crown specifications. You’ll know exactly what you’re paying for and why.
- 4
Professional installation or rebuild. Most liner replacements are completed in a single visit. Rebuilds typically take two to three days depending on weather and scaffolding requirements. We protect your property with drop cloths, contain dust with HEPA filtration when cutting masonry, and work methodically. Our technicians are employees, not subcontractors, and they’ve been trained to Hearthstone’s standards.
- 5
Final inspection, documentation, and 90-Day Done Right Promise. We video-scan the completed liner installation or photograph the rebuilt chimney from multiple angles. You receive all documentation, a written warranty, and our promise: if it’s not done right, we make it right. No paperwork to file, no arguments. Call us and we return.
How Much Does Chimney Liner & Rebuild Cost in Woburn?
If you’re wondering how much Chimney Liner & Rebuild costs, a typical stainless steel liner replacement in Woburn runs $2,800 to $4,500 depending on flue diameter, chimney height, and whether your appliance requires a direct connection or a separate liner. Flexible liner installations for gas inserts or offset chimneys generally fall between $2,200 and $3,800. Partial rebuilds from the roofline up range from $4,500 to $8,000 based on linear feet of masonry and scaffold requirements. Full chimney rebuilds start around $12,000 and can reach $20,000 or more for multi-flue structures with complex crown configurations.
Several factors move these numbers. Chimney height above the roofline affects material quantities and labor hours. Accessibility determines whether we need scaffolding or can work from ladders and roof jacks. The condition of the existing liner, if one exists, influences removal difficulty. And Massachusetts code requires proper clearances to combustibles, which sometimes means modifying adjacent framing or installing additional insulation.
To avoid overpaying, get a Level-2 inspection with camera documentation before accepting any bid. We’ve seen Woburn homeowners quoted for full rebuilds when a targeted liner replacement would have solved the problem, and we’ve seen cut-rate liner jobs that failed inspection because the installer used the wrong diameter or skipped insulation. Our free estimate includes the camera inspection, and we’ll tell you plainly when work can safely wait a season and when it cannot.
Every estimate includes materials, labor, permit coordination with the Woburn Building Department if required, debris removal, and the 90-Day Done Right Promise. We also honor our standing offers: $50 off any repair over $250, a free second opinion on any written estimate, and a permanent 5% senior and veteran discount.
