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.
Trusted Chimney Liner & Rebuild for Boston Homeowners
A Chimney Liner & Rebuild in Boston typically costs between $2,800 and $8,500 depending on whether you’re replacing a damaged liner or rebuilding masonry from the roofline up. Most liner replacements are completed in a single day, while full rebuilds usually take two to three days with weather permitting. Hearthstone Chimney Co. has been serving Boston homeowners since 1984, and we document every project with photos and a plain-English verdict so you know exactly what was done and why.
Boston’s freeze-thaw cycles, coastal salt air, and century-old housing stock take a toll on chimney systems that newer cities simply don’t face. We’ve replaced crumbling terra-cotta liners in Back Bay brownstones, rebuilt spalling brickwork in Dorchester triple-deckers, and installed flexible stainless steel liners through the tight flue passages of Beacon Hill’s narrow chimney stacks. Russell Haines built this company on the principle that a homeowner should never pay for work they can’t see or understand. That’s why we still answer the phone with a live person 24 hours a day, 7 days a week at (857) 597-5950, and why every job carries our 90-Day Done Right Promise in writing.
Our technicians are background-checked, uniformed, and equipped to complete most liner and rebuild jobs in a single visit. We use professional-grade materials from HeatShield, Gelco, Olympia Chimney, and other industry-trusted brands - never builder-grade substitutes that fail in Boston’s harsh winters. When you call, we’ll schedule a Level-2 camera inspection, show you exactly what we find, and give you no-hassle upfront pricing before any work begins.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue pipe that protects your chimney walls from corrosive flue gases and contains the heat of combustion. In Boston, we install stainless steel liners most often in homes with oil or gas heating systems where the original terra-cotta liner has cracked or deteriorated from decades of thermal cycling. Our crews measure your flue precisely, then fabricate and install a Chimney Liner & Rebuild in Boston using heavy-gauge 316Ti alloy from Olympia Chimney, rated for continuous operation at high temperatures.

Flexible Liner
Flexible liners are corrugated stainless steel tubes that can navigate offset flues, chimney bends, and tight spaces where rigid pipe won’t fit. These are essential in Boston’s older neighborhoods - particularly the North End, Charlestown, and parts of Roxbury - where chimneys were built with offsets to dodge timber framing or adjacent structures. We source our flexible liners from DuraFlex and Gelco, and our technicians have the specialized equipment to pull them through without damaging surrounding masonry.

Liner Replacement
Liner replacement becomes necessary when your existing flue liner is cracked, spalled, or missing sections that allow heat and combustion gases to reach combustible framing. In Boston, we see this most often in homes built between 1880 and 1940 where original terra-cotta liners have simply reached end of life. We remove the damaged liner carefully to avoid dropping debris into your firebox or heating appliance, then install a new system sized precisely for your appliance’s BTU output and venting requirements.

Partial Rebuild
A partial rebuild addresses damage confined to the upper portion of your chimney - typically the top four to eight courses of brick, the crown, and sometimes the flue tiles immediately below. Boston’s freeze-thaw damage concentrates here because the crown is the chimney’s most exposed surface. In neighborhoods like Jamaica Plain and West Roxbury, we’ve rebuilt hundreds of chimney tops where water infiltration has destroyed the mortar bond but the lower structure remains sound. We match existing brick and mortar color where possible, and we always install a proper concrete crown with drip edge to prevent recurrence.

Full Chimney Rebuild
Full chimney rebuilds are required when structural damage extends below the roofline, when multiple flues have collapsed, or when the chimney has separated from the house wall. This is more common in Boston than in newer cities because our housing stock includes so many unlined or single-wythe brick chimneys built before modern codes. We dismantle the damaged section course by course, salvage usable brick when matching is critical, and rebuild to current Massachusetts building code with proper lining, insulation, and clearances. Every full rebuild includes a new crown, cap, and flashing integration with your roofing.

Liner Repair
Liner repair is a targeted alternative to full replacement when damage is localized - a few cracked flue tiles, minor joint gaps, or early-stage spalling. We use HeatShield’s cerfractory sealant system, which is rated to 2900°F and applied with specialized foam plugs that smooth the flue surface while filling gaps. In Boston, this approach works well for homeowners in South Boston and East Boston who need to extend liner life five to ten years before a full replacement becomes necessary. We only recommend repair after camera inspection confirms the surrounding liner is structurally sound.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced HeatShield repair systems in hundreds of Boston-area homes since the product first came to market. The cerfractory compound bonds to existing terra-cotta and creates a surface that withstands the acidic condensation produced by modern, efficient appliances. Our technicians are factory-trained in HeatShield application, and we stock the full range of foam former sizes so we’re not guessing at your flue dimensions.
Gelco and Olympia Chimney supply the stainless steel components we use for new liner installations. Gelco’s flexible liners navigate tight offsets without the tearing we’ve seen in lesser products, and their termination caps include the animal-proof screening that Boston’s squirrel and raccoon populations demand. Olympia Chimney’s rigid stainless systems are our choice for straight flues and commercial applications where maximum draft efficiency matters. Whether your existing system was installed by another company using these brands or any other make, we can inspect, repair, or replace it. We also work regularly with Famco termination fittings and Copperfield chimney accessories when specific applications call for them.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick means water is moving through your masonry and dissolving salts. In Boston, this accelerates dramatically after January cold snaps when trapped moisture freezes and expands. Left alone, the freeze-thaw cycle destroys mortar joints and spalls brick faces, turning a liner problem into a structural rebuild.
- Bits of terra-cotta or brick in your firebox or cleanout are pieces of your liner or chimney structure that have already failed. This debris indicates active deterioration, and every piece that falls means less protection between combustion gases and your home’s framing. We find this most often in chimneys that haven’t been inspected in five or more years.
- Smoke or odors entering living spaces when the system is not in use suggests liner gaps or negative pressure issues that allow downdrafting. Boston’s tight, energy-efficient homes are particularly susceptible to this because modern weatherization reduces the natural air exchange that once masked minor venting problems. A compromised liner makes this dangerous, not merely unpleasant.
- Deteriorating mortar joints you can pick apart with a screwdriver mean water has penetrated and weakened the bond. In coastal Boston neighborhoods like Hull, Revere, and parts of Quincy, salt-laden air accelerates this decay. Tuckpointing can address surface damage, but if the liner is also failed, you’re treating symptoms while the underlying disease progresses.
- Your heating technician has flagged “improper venting” or “failed liner” in service notes and you haven’t followed up. This is not a recommendation to consider later. Massachusetts code requires proper venting for all fuel-burning appliances, and your HVAC company may be legally required to red-tag the system if you don’t address it. We provide second opinions on any written estimate at no charge.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule your Level-2 camera inspection. When you call (857) 597-5950, a live person answers - no voicemail, no callback queue. We’ll find a time that works, and our technician arrives in a marked vehicle with photo ID. The inspection takes 45 to 90 minutes depending on chimney height and accessibility.
- 2
Document everything with video and still photography. We run a high-resolution camera up your flue and record the entire surface, noting cracks, gaps, glaze buildup, and structural defects. You see what we see. There’s no “trust us” - the evidence is on screen, and we explain what each finding means in plain English.
- 3
Receive your written verdict and upfront pricing. Russell Haines insists that every homeowner gets a clear diagnosis and a single number before any work is authorized. If the liner is cracked but the masonry is sound, we say so. If the chimney needs rebuild work that can safely wait a season, we say that too. The estimate you sign is the invoice you pay.
- 4
Complete the work with professional-grade materials. Our crews arrive with the specific components your job requires - HeatShield compound for repairs, Gelco or Olympia Chimney liner systems for replacements, matching brick and Type N or Type S mortar for rebuilds. Most liner replacements and partial rebuilds finish in one day. Full rebuilds typically require two to three days with weather hold days as needed.
- 5
Final inspection, photo documentation, and written guarantee. We camera-verify liner installations and visual-inspect rebuild work before we leave. You receive photos of the completed work, a written summary, and our 90-Day Done Right Promise. If anything isn’t right, we make it right - no paperwork, no arguing, just the thing done correctly.
How Much Does Chimney Liner & Rebuild Cost in Boston?
A typical stainless steel liner replacement in Boston runs $2,800 to $4,500 for a single-flue system, depending on height, diameter, and whether your chimney requires insulation wrap to meet clearances. Flexible liner installations in tight, offset flues range from $3,200 to $5,000 because of the additional labor in navigating bends. Partial rebuilds - top four to eight courses plus crown - generally cost $3,500 to $6,000, while full chimney rebuilds from the roofline down range from $6,500 to $12,000 depending on height, brick matching requirements, and whether multiple flues are involved. HeatShield liner repairs are the most economical option at $1,800 to $2,800 when the damage is localized and the surrounding liner is sound.
Several factors push these numbers up or down. Chimney height is the most significant - a three-story Beacon Hill brownstone simply requires more material and more labor than a two-story Cape in West Roxbury. Access matters too: chimneys tucked between buildings or with limited staging area take longer. Brick matching for historic properties can add cost if we need to source reclaimed material. And the condition of your existing flue affects whether we can use a simple insert or must remove debris and smooth the passage first.
The most expensive mistake is paying for work you don’t need based on a visual inspection alone. We’ve seen Boston homeowners quoted $8,000 for “emergency rebuilds” when a $2,800 liner replacement would have solved the problem safely. That’s why we include camera evidence with every estimate, and why we offer free second opinions on any written estimate from another company. Our $89 Seasonal Tune-Up includes a basic inspection that can catch problems before they become expensive emergencies. And if you’re over 55 or a veteran, we apply a permanent 5% discount to every invoice - no coupon required.
Call (857) 597-5950 for your free estimate. We’ll inspect, document, and price your job with no obligation and no pressure.

Frequently Asked Questions - Chimney Liner & Rebuild in Boston
Chimney liner and rebuild work restores the safe passage for combustion gases from your heating appliance or fireplace to the outside air. The liner protects your chimney’s masonry from corrosive byproducts and prevents heat transfer to combustible framing; rebuild work repairs or replaces damaged brick, mortar, crowns, and caps that protect the structure. In Boston’s older housing stock, these systems often fail simultaneously after decades of freeze-thaw stress.
Most stainless steel liner replacements are completed in a single day, while flexible liner installations in offset flues may take a day and a half. Partial rebuilds typically require one to two days, and full chimney rebuilds from the roofline down usually take two to three days with weather hold days as needed. We complete most jobs in a single visit when possible, and we never leave your home unprotected - temporary rain caps go up if work pauses.
Chimney liner replacement in Boston typically ranges from $2,800 to $5,000 depending on liner type and flue complexity; partial rebuilds run $3,500 to $6,000; and full rebuilds range from $6,500 to $12,000. The only way to know your exact cost is through a Level-2 camera inspection that reveals the actual condition of your system. Call (857) 597-5950 for a free estimate - we’ll show you what we find and give you a firm number before any work begins.
Yes. We install, repair, and replace HeatShield, Gelco, and Olympia Chimney products regularly, and our technicians are trained in each manufacturer’s specific requirements. We also service systems installed by other companies using these brands, and we can source Famco and Copperfield accessories when specific applications require them. If you have a different brand, we can almost certainly help - call us with the details.
It can be. A failed liner in an active heating system risks carbon monoxide leakage into living spaces and chimney fires if creosote ignites in gaps between the liner and masonry. However, not every crack requires immediate action - some can be monitored or repaired if caught early. We assess urgency honestly after camera inspection, and we’ll tell you plainly when work can safely wait versus when it needs immediate attention.
