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.

Why Hearthstone Chimney Co. Is Somerville’s Preferred Fireplace Services Company
We’ve worked on Somerville chimneys for decades. We know the 1880-to-1930 housing stock, the shared triple-decker stacks on streets like Broadway and Highland Avenue, and the specific problems that come from venting modern appliances into flues built for coal. Our Fireplace Services team doesn’t guess, and we don’t upsell.
Our Level 2 camera inspections end with photos you can see and a plain-English verdict. If your flue is cracked, you’ll see the crack. If mortar between flues has failed, we’ll show you the gap. Nothing is recommended without evidence you can verify yourself.
We answer our phones with a live person, 24 hours a day, 7 days a week. Our technicians are background-checked and uniformed, and most jobs are completed in a single visit. Our 90-Day Done Right Promise is in writing with no arguing - if it’s not right, we come back and make it right.
We’re not a price-cutting chain, and we’re not a one-truck operator who might answer next week. We’ve served local communities for over 42 years, and we plan to be here in thirty more.
Our Fireplace Services in Somerville
Gas Fireplace Service
Gas fireplaces in Somerville often vent into chimneys never designed for them. The original coal flues in Winter Hill and Magoun Square triple-deckers are frequently oversized, unlined, and missing the proper draft characteristics for modern gas units. We inspect the venting path with a camera, check for condensation damage in the flue, and verify that your gas logs or insert are drafting safely. A typical gas fireplace service in Somerville runs $180-$320. If the flue needs relining for safe gas venting, we’ll show you why and give you a square deal on the repair.

Wood Burning Fireplace
Somerville’s cold winters push residents toward supplemental wood heat, but burning in an unlined or damaged flue is a genuine hazard. Eastern Massachusetts freeze-thaw cycles steadily spall mortar joints on aging brick stacks, and creosote accumulates faster in flues that are undersized or improperly converted from their original fuel type. We clean, inspect with a camera, and assess whether your wood-burning fireplace can operate safely as-is or needs structural repair. Most wood fireplace inspections and sweeps in Somerville cost $280-$450.

Fireplace Insert Installation
A fireplace insert is often the right solution for a Somerville homeowner with a drafty, inefficient masonry fireplace - but only if the chimney is properly lined for it. Inserts require a correctly sized stainless steel liner from the unit to the top of the flue, and many Somerville chimneys lack any liner at all. We measure, camera-inspect, and install inserts with DuraFlex or Olympia Chimney liners sized precisely for your appliance. A complete insert installation with liner in Somerville typically runs $2,200-$3,800. We handle the full job in one visit when possible, and the price we quote is the price on the invoice.

Damper Repair & Replacement
Throat dampers in Somerville’s older fireplaces corrode, warp, or seize after decades of disuse. A failed damper lets heated air escape up the chimney year-round and can allow smoke to backdraft into your living space. We repair or replace throat dampers and install top-sealing dampers from Famco when the original is beyond saving. Most damper repairs in Somerville cost $350-$850 depending on access and whether the firebox throat needs masonry rebuilding. We inspect with a camera first so you know exactly what you’re paying for.

Firebox Repair
The firebox - the actual chamber where fuel burns - takes the most direct heat abuse. In Somerville’s century-old fireplaces, firebrick cracks and mortar joints crumble, exposing surrounding framing to heat and creating a real fire risk. We rebuild fireboxes with proper refractory materials, matching original dimensions where possible. A firebox repair or partial rebuild in Somerville typically runs $1,400-$2,800. We document the damage with photos before we quote, and we never recommend a full rebuild when spot repairs will safely suffice.

Fireplace Conversion
Converting a wood-burning fireplace to gas in Somerville requires more than running a gas line. The chimney must be evaluated for proper venting, and in multi-flue triple-decker stacks, we must verify that conversion doesn’t create draft conflicts with neighboring units. We handle conversions with proper permits, camera verification, and liners installed to manufacturer specifications. Conversion costs in Somerville range from $1,800-$3,200 depending on gas line routing and liner requirements.

Trusted Brands We Service in Somerville
We work exclusively with professional-grade materials from industry-trusted brands. For Somerville’s demanding conditions - freeze-thaw cycles, multi-flue stacks, and century-old masonry - we specify DuraFlex stainless steel liners, HeatShield cerfractory flue resurfacing, and Famco dampers and caps. We stock common parts locally so repairs don’t wait on shipping. No builder-grade substitutes, no corner-cutting. Done right, and we stand behind it.
Common Fireplace Services Problems We See in Somerville Homes
- Carbon monoxide crossover between triple-decker units. When mortar separating flues in a shared stack crumbles, combustion gases from one apartment can migrate into a neighbor’s flue. A Level 1 visual inspection from the top won’t catch this. Our camera inspection will.
- Original coal-era flues with no liner, now venting gas or wood. These unlined brick flues crack and spall through freeze-thaw cycles, so appliances draft poorly and combustion gases back up rather than venting safely to the outside.
- Landlords treating three flues as one system. We frequently find that only one flue in a triple-decker stack has been cleaned or inspected, leaving the other two unexamined and potentially hazardous for tenants.
- Third-degree creosote in converted wood-burning flues. Somerville residents who burn wood for supplemental heat often don’t realize their flue was sized for coal or oil. Undersized flues run cooler, and cool flues accumulate glazed creosote that can’t be brushed out with standard sweeping.

The Somerville Triple-Decker Problem: What Other Companies Miss
Somerville’s housing stock is overwhelmingly triple-deckers - three-unit stacked rental buildings whose single chimney stack typically contains two or three separate masonry flues serving individual units. This means nearly every chimney job involves a landlord-owned multi-flue stack where degraded mortar between flues creates a real carbon-monoxide crossover risk between tenants, a scenario largely absent in single-family suburban markets.
In a triple-decker off Broadway in Winter Hill, our tech ran a Level 2 inspection on a shared brick stack and found the mortar between the first-floor and second-floor flues had crumbled away, with second-degree creosote lining the second-floor flue and visible gas migration between flues. We camera-scoped both flues, showed the homeowner and landlord the footage on our monitor, and installed a HeatShield flue liner in each flue to restore separation before anyone burned again.
This is why we insist on camera inspection for every Somerville fireplace we service. A visual check from the roof or a quick sweep of one flue leaves the real hazard undiscovered. We’ll be there when we say, we’ll show you what we find, and we’ll give you a plain-English verdict you can act on.

FAQs - Fireplace Services in Somerville
Yes. Each flue is a separate venting system, and each must be inspected individually with a camera. In Somerville’s triple-deckers, we regularly find that one flue is deteriorating while another appears sound, or that mortar between flues has failed and is allowing gas crossover. A landlord who treats the chimney as one system and approves a single cleaning is leaving two units unprotected. We document each flue separately with photos and a written verdict for every unit. Call (781) 905-8338 to schedule - estimates are free.

Only if the chimney is properly lined and sized for the appliance. Somerville’s original coal flues are typically oversized for modern gas units, which causes condensation, corrosion, and poor draft. We camera-inspect the flue, measure for proper sizing, and install a correctly sized stainless steel liner before any gas fireplace or insert is connected. Venting gas into an unlined coal flue is not safe and is not something we do. Call (781) 905-8338 for a camera inspection and proper sizing assessment.

Smoke odor migrating between units indicates a failed mortar joint or crack between flues in your shared chimney stack. This is a known hazard in Somerville triple-deckers, where multiple flues share one brick structure and decades of freeze-thaw damage erode the separating mortar. The smell is a warning sign; carbon monoxide can follow the same path. We locate the breach with a camera inspection and restore flue separation with proper lining or repair. Call (781) 905-8338 immediately - this condition should not wait.

Third-degree creosote is a hardened, tar-like deposit that forms when wood smoke condenses in a cool or improperly sized flue. It cannot be removed with standard brushing. In Somerville, we see this frequently in flues originally built for coal or oil that are now being used for wood burning - they’re too large to stay hot enough, so creosote glazes onto the flue walls. Removal requires specialized chemical treatment or mechanical removal, and in severe cases, relining is the safer long-term solution. We assess with a camera and recommend the least invasive fix that leaves your chimney safe.

Yes. Even minimal use creates some combustion residue, and in Somerville’s triple-decker housing, the condition of your flue affects your neighbors’ safety too. More importantly, an unused fireplace and chimney deteriorate from the outside - freeze-thaw damage, moisture intrusion, and animal nesting don’t require a fire to create hazards. Annual inspection catches these issues before they become expensive or dangerous. Our Level 2 camera inspection gives you documented proof of your chimney’s condition, whether you burn daily or once a season. Call (781) 905-8338 to schedule - estimates are free.
