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.
Fast, Reliable Chimney Liner & Rebuild Across Belmont
Most chimney liner and rebuild jobs in Belmont run $1,800-$4,500 for liner replacement and $3,500-$8,500 for partial or full rebuilds, with our Chimney Liner & Rebuild team typically completing inspections within 48 hours and most installations in a single visit. If your Belmont home was built before 1940, there’s a strong chance your chimney was sized for coal and later converted to oil or gas without proper relining, a mismatch that causes chronic draft problems and hidden safety hazards.

We’ve been serving Belmont and surrounding communities for over 42 years.

Why Hearthstone Chimney Co. Is Belmont’s Preferred Chimney Liner & Rebuild Company

The 90-Day Done Right Promise governs every job: in writing, no arguing. If it’s not right, we come back. That promise has been our standard since 1984, and it’s why Belmont customers refer us to neighbors.
Our background-checked, uniformed technicians complete most liner and rebuild jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. And a live person answers every call, 24 hours a day, 7 days a week - not voicemail, not a callback queue.

Our Chimney Liner & Rebuild Services in Belmont
Stainless Steel Liner Installation
A properly sized stainless steel liner is the correct fix for most Belmont chimneys with unlined or deteriorated clay flues. We install DuraFlex and Olympia Chimney stainless systems cut to the exact length and diameter your appliance requires, not the oversized coal-era cross-section your chimney originally contained. On a 1918 Colonial Revival off Payson Road, our tech ran a Level 2 inspection and the camera showed the furnace flue was bare, oversized brick with no liner at all - acidic condensate from the gas conversion had been eating the mortar joints for years. We installed a properly sized stainless DuraFlex liner, rebuilt the smoke chamber, and handled Chimney Repair in Belmont to reset the crown and cap; the draft test afterward was the first clean reading that chimney had likely ever produced. Most stainless liner installations in Belmont run $2,200-$3,800.

Flexible Liner Solutions
Flexible liners navigate offset flues and tight smoke chambers common in Belmont’s two- and three-story Colonial Revival and Tudor chimneys. We use professional-grade flexible systems from DuraFlex when rigid pipe won’t make the turn. Flexible liner installation in Belmont typically costs $1,800-$3,200, depending on flue length and access.

Liner Replacement
When an existing liner has failed - cracked clay tiles, corroded metal, or gaps at the joints - full replacement is the only safe option. In Belmont’s pre-1940 housing stock, we frequently find that a “recent” liner from a previous owner was improperly sized for the current appliance, or was installed without addressing the deteriorated mortar behind it. We pull the old material, inspect the surrounding masonry with a camera, and install a new system that matches your appliance’s venting requirements. Liner replacement in Belmont generally runs $2,500-$4,500.

Partial Chimney Rebuild
Belmont’s severe freeze-thaw cycle destroys soft, lime-mortared brickwork at the crown, shoulders, and above the roofline. A partial rebuild addresses the damaged section without the cost of full reconstruction. We match existing brick and mortar where possible, install proper crown flashing, and ensure the rebuilt section vents through a correctly sized liner. Partial rebuilds in Belmont typically cost $3,500-$6,500.

Trusted Brands We Service in Belmont
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. For Belmont customers, this means we stock common liner diameters and rebuild components locally, so most jobs don’t wait on parts. When we recommend a specific brand for your chimney, it’s because that product is engineered for your fuel type, flue size, and local conditions, not because it’s what we had on the truck.
Common Chimney Liner & Rebuild Problems We See in Belmont Homes
- Unlined flues from coal-to-gas conversions. Original oversized multi-flue chimneys in Belmont Hill and Payson Park were converted from coal to oil to gas without relining, so the appliance can’t establish draft and creosote builds quickly in a flue it was never sized for.
- Freeze-thaw spalling on soft lime mortar. Belmont’s position on a glacial ridge exposes chimneys to full-force nor’easters, and the November-through-March freeze-thaw cycle rapidly degrades pre-1940 brickwork at crowns and flashing, letting moisture wick into unlined flues.
- Moisture trapping under dense tree canopy. Belmont’s unusually heavy tree cover over residential streets means leaf and debris accumulation in chimney tops is a consistent seasonal problem that accelerates liner breakdown and hides third-degree creosote glaze.
- Acidic condensate eating bare brick. In the Belmont Hill estate neighborhood, technicians frequently open up a large 1910s chimney expecting routine service and find gas appliances venting directly into unlined, oversized flues - code violations that deposit acidic moisture and creosote inside bare brick for years.

FAQs - Chimney Liner & Rebuild in Belmont
Your chimney was likely built for coal, converted to oil, then converted to gas without resizing the flue. A modern low-BTU gas appliance needs a much smaller cross-section to generate proper draft; in an oversized flue, exhaust cools too quickly, draft collapses, and creosote condenses on the walls. Newer construction in Burlington and Woburn was built with correctly sized flues from the start. Call (781) 905-8338 for a camera inspection that will show exactly what’s happening inside your flue.
Visible cracks are only one failure mode. In Belmont, we frequently find chimneys with no visible tile damage but with no liner at all - just bare brick venting acidic gas exhaust. Or the “liner” is a deteriorated clay system from the 1960s with gaps at the joints that a standard sweep can’t see. Our Level 2 inspection with camera documentation shows you exactly what is or isn’t there. Call (781) 905-8338 to schedule - estimates are free.
Nothing is recommended without camera evidence you can see for yourself, and we plainly tell you when work can safely wait. The 90-Day Done Right Promise means we have to come back if anything fails - so overselling a rebuild we don’t believe in costs us twice. Our estimates also include a Free Second Opinion on any written estimate from another company. Call (781) 905-8338.
Third-degree creosote glaze is the dangerous form, and it forms faster in Belmont’s oversized, unlined flues where poor draft keeps exhaust gases cool and sticky. It’s hard as glass, a brush won’t remove it, and it’s highly combustible. We find it hidden under leaf debris in chimneys under Belmont’s dense tree canopy, where moisture retention accelerates buildup. Call (781) 905-8338 if you suspect glazing - removal requires specialized equipment.
Every year, regardless of use. In Belmont, gas appliances venting into unlined flues produce acidic condensate 24/7 during heating season, and freeze-thaw damage progresses whether you light fires or not. Annual Level 2 inspection catches liner failure and masonry deterioration before they become safety hazards. Call (781) 905-8338 to schedule - the $89 Seasonal Tune-Up includes basic inspection, and seniors and veterans receive a permanent 5% discount.
