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.

Our Chimney Liner & Rebuild Services in Belmont
Stainless Steel Liner Installation
Belmont’s original clay flue tiles, installed when coal furnaces were standard, crack from decades of freeze-thaw cycling and are often undersized for modern gas appliances. A stainless steel liner from DuraFlex creates a sealed, properly sized flue that vents efficiently and meets current code. We size every liner to the appliance it serves - critical on Belmont Hill, where gas log inserts are frequently added to original fireplaces without proper relining.
Flexible Liner Solutions
Some of Belmont’s older chimneys have offset flues or tight cleanouts that make rigid liner installation impractical. Flexible stainless liners navigate these obstacles without breaking into walls. Our crews have run flexible liners through the twisted flues common in pre-WWII Tudors near Trapelo Road, restoring safe venting without disrupting original plaster or trim.
Liner Replacement
When a clay liner is cracked, spalled, or separated at the joints, patching is rarely worth the gamble. We extract the damaged liner and install a new stainless system sized to your heating appliance or fireplace. On Belmont’s streetcar-era colonials, we regularly find liners that were never replaced during the conversion from coal to gas - an 80-year-old clay flue venting a modern high-efficiency furnace is a carbon monoxide risk hidden behind handsome brick.
Partial Rebuild
Not every failing chimney needs to come down. When the crown, top courses, or firebox are damaged but the structural shell is sound, we rebuild only what failed. Belmont’s corbeled chimney caps are a prime example - the soft historic mortar erodes faster than the brick below, especially on north- and east-facing exposures. We rebuild the crown with a flexible membrane, replace damaged brick, and install proper flashing. Done right, and we stand behind it.

Common Chimney Liner & Rebuild Problems We See in Belmont Homes
- Cracked clay flue tiles venting carbon monoxide into living spaces. Belmont’s 80-100-year-old clay liners were built for coal, not gas. They crack from thermal cycling and vent exhaust into wall cavities and living spaces behind a pristine exterior. Our camera inspection finds what eyes cannot.
- Corbeled crowns eroding on north- and east-facing exposures. Belmont’s streetcar-era colonials often have corbeled chimney caps made of soft historic mortar, which erode faster than the brick below and are the first thing our techs see crumbling on north-facing flues near Belmont Hill. Water pours through the gaps, rusting dampers and soaking smoke chambers.
- Galvanized caps and flashing corroded from nor’easter-driven rain and ice. Galvanized components fail within a decade in Belmont’s climate. Stainless steel caps and flashing last the life of the chimney. The difference is real, and visible on inspection.
- Oversized flues venting low-BTU gas appliances. On Belmont Hill and streets north of Trapelo Road, kitchen-and-bath renovations often include decorative gas log inserts without proper relining. An oversized wood-burning flue venting a small gas appliance causes chronic condensation, accelerated liner deterioration, and failed sale inspections.

FAQs - Chimney Liner & Rebuild in Belmont
Yes, almost certainly. An oversized wood-burning flue venting a low-BTU gas appliance causes chronic condensation that destroys clay liners and creates a carbon monoxide pathway into your home. We see this constantly on Belmont Hill and north of Trapelo Road, where renovations add gas logs without permits or relining. Our camera inspection will confirm the flue condition and size a stainless liner to the appliance. Call (857) 392-4709 for an exact quote - estimates are free.
Every year, before burning season. Belmont sits just inland enough to experience full northeastern freeze-thaw cycling, with repeated temperature swings across 32°F that accelerate mortar erosion and spalling. Nor’easters drive rain and ice directly into unprotected flue openings. Annual camera inspection catches crown erosion and liner cracks before they become water damage or carbon monoxide hazards. Call (857) 392-4709 to schedule - estimates are free.
The crown fails first, visibly. Belmont’s corbeled chimney caps, made of soft historic mortar, erode faster than the brick below, especially on north- and east-facing exposures. But the liner often fails silently - cracked clay tiles venting exhaust into wall cavities while the crown still looks merely weathered. Our Level-2 inspection checks both, with photos you can see. Call (857) 392-4709 for an exact quote - estimates are free.
Yes. Galvanized caps and flashing corrode within a decade from nor’easter-driven rain and ice in Belmont’s climate. Stainless components last the life of the chimney. The upfront cost difference is modest; the replacement cost of corroded flashing and water-damaged brick is not. We install only stainless on our Belmont jobs. Call (857) 392-4709 for an exact quote - estimates are free.
A partial rebuild addresses the crown, top courses, firebox, or smoke chamber while the structural shell remains sound - common when Belmont’s corbeled caps fail but the brick below is solid. A full rebuild is necessary when spalling, leaning, or compromised mortar joints affect the structural wythe. Our inspection determines which applies, and we never recommend full rebuild when partial will suffice. Photos you can see, a plain-English verdict. Call (857) 392-4709 for an exact quote - estimates are free.
On a 1920s Colonial Revival off Trapelo Road, our crew found the original corbeled crown spalling and a cracked clay flue liner that had been venting a new gas log insert for three winters. We installed a stainless steel DuraFlex liner sized for the low-BTU appliance and rebuilt the crown with a flexible membrane, stopping the condensation that had been soaking the smoke chamber. The homeowner had no idea until the inspection - the brick exterior looked fine.
That’s the pattern we see in Belmont: chimneys that look sound from the street, with hidden failures that only a camera inspection reveals. If your home was built between 1905 and 1945, your flue was built for coal. Let us show you what it looks like now.
