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 Medford’s Preferred Fireplace Services Company
Medford homeowners know the difference between a sweep who understands triple-decker flue assignments and one who treats every chimney like a suburban ranch stack. We’ve been serving local communities for over 42 years, and our reputation here was built on figuring out which flue serves which tenant before we ever light a brush.
Our reviews from Medford customers consistently mention the same things: the technician showed up in uniform, explained what the camera found in plain English, and the price matched the estimate exactly. No paperwork to file for the 90-Day Done Right Promise - if it’s not right, we come back, in writing, no arguing.
Response time to Medford neighborhoods is typically same-week during shoulder season and within a few days during peak pre-winter demand. We don’t promise same-day dispatch because a proper fireplace inspection in a triple-decker requires coordinating access with multiple tenants, and we’d rather do it right than do it fast and miss an open flue bleeding draft from your neighbor’s unit.
Local knowledge matters here. Medford’s late-19th and early-20th century housing stock - brick triple-deckers, Queen Anne cottages, Colonial Revival singles - was built with rubble-stone or brick-lined stacks and lime-based mortar that’s now past the century mark. These chimneys were designed for coal, adapted for oil, and now vent gas appliances through passages that are often oversized and acid-damaged. A sweep who doesn’t know that history can clean a flue thoroughly and still miss the structural problem that’ll cost you thousands.
Our Fireplace Services in Medford
Gas Fireplace Service
Gas fireplaces in Medford’s converted triple-deckers often struggle because they’re venting through flues that were never properly resized when the building switched from oil. The logs light, but the flame pattern is wrong, the glass soots, and the carbon monoxide risk rises. We start every gas fireplace service with a Level 2 camera inspection to verify flue sizing, check the termination cap for proper clearance, and test draft under operating conditions. In West Medford especially, we find gas log sets installed by previous owners who never realized the flue was shared with a decommissioned oil unit next door. That’s not a cleaning problem. That’s a venting assignment problem, and we fix it.

Wood Burning Fireplace
Wood burning fireplaces in Medford’s older singles - the ones with original brick fireboxes and throat dampers - face a specific enemy: the Mystic River valley’s moisture combined with freeze-thaw cycling from November through March. Water gets in through a cracked crown or failed flashing, freezes in the mortar joints, and by spring you’ve got spalling brick and a firebox that’s no longer structurally sound. We inspect wood burning fireplaces with the camera before we sweep, because creosote removal on a deteriorated liner can expose gaps you didn’t know were there. If the firebox brick is compromised, we’ll show you the photos and explain whether HeatShield refractory resurfacing or a full rebuild is the honest call.

Fireplace Insert
A fireplace insert is often the right solution for Medford homeowners with an oversized, unlined flue that’s too large to vent a modern appliance efficiently. We measure the existing firebox and flue, spec the insert to fit, and handle the full installation including the stainless steel liner from DuraFlex or Olympia Chimney - whichever matches your venting requirements. In Hillside triple-deckers, we frequently install inserts in first-floor units where the original flue was designed for a coal furnace and now creates chronic downdraft. The insert’s sealed combustion and dedicated liner solve both the draft problem and the heat-loss problem. Upfront pricing includes the liner, the surround, and the final inspection. One visit for measurement, one visit for installation.

Damper Repair
Damper repair is one of our most common calls in Medford, and it’s rarely just a rusted throat plate. In the field vignette we see again and again: a second-floor tenant in West Medford calls because the gas log set keeps stalling and there’s a stain on the ceiling below. Our tech pulls the cap and finds a decommissioned oil flue left wide open next to the active one, its original liner unsealed, with the shared masonry wicking moisture from the Mystic valley and rusting the damper frame solid. We capped and relined the abandoned flue and reset the damper so the active fireplace could establish draft again. That’s Medford-specific work. A suburban sweep might replace the damper and wonder why it rusted again in two years.

Firebox Repair
Firebox repair in Medford addresses what happens after water has been getting in for seasons without anyone noticing. The first sign is often a loose brick or a hairline crack in the refractory panel, but the real damage is behind it - deteriorated mortar, rusted lintels, sometimes compromised structural support. We document everything with the camera, show you exactly what we’re seeing, and quote firebox repair with no pressure to add work that can wait. For minor refractory damage, we use HeatShield cerfractory foam to resurface the panels. For structural brick work, we rebuild with firebrick and high-temperature mortar rated to the appliance. Either way, you get photos, a plain-English verdict, and the 90-Day Done Right Promise in writing.

Fireplace Conversion
Fireplace conversion - typically wood-to-gas or oil-to-gas - requires careful flue analysis in Medford’s multi-family housing. Converting without verifying which flue serves which unit, and whether abandoned flues are properly capped, creates the exact moisture and draft problems we spend our winters fixing. We handle the conversion start to finish: gas line coordination, insert or log set selection, liner installation, permit documentation, and final inspection. The price depends on whether the existing flue can be relined or whether we need to address adjacent abandoned flues first. We’ll tell you straight which path makes sense.

Trusted Brands We Service in Medford
We stock parts and materials from the brands that professional sweeps actually trust: DuraFlex stainless steel liners for relining oversized flues, HeatShield refractory systems for firebox resurfacing, and Famco caps and dampers for replacement in weather-exposed conditions. For Medford customers, that means faster turnaround - we don’t order parts after we diagnose the problem, we carry what this city’s housing stock typically needs. Copperfield masonry supplies for brick rebuilds. Olympia Chimney liners for insert installations. No builder-grade substitutes, no waiting two weeks for a part that should be on the truck.
Common Fireplace Services Problems We See in Medford Homes
- Wind-driven rain through cracked crowns. Medford’s exposed chimney crowns take the brunt of nor’easter winds coming off the Mystic valley. Water rides into a crown already cracked by November-March freeze-thaw, hits the smoke chamber, and the first sign is a ceiling stain rather than anything visible from the driveway. By the time you see the stain, the firebox brick is often saturated.
- Displaced or missing chimney caps. A cap that blew off in a storm lets water and animals into an open flue, so the shared brick stack stays wet year-round and the mortar joints spall from the inside out. We find this constantly in Medford triple-deckers where the cap was last replaced decades ago and the landlord never noticed it was gone.
- Step flashing separation at the roof-to-chimney junction. After a severe storm, the step flashing separates and wicks water behind the brick, showing up as damp firebox brick and a failed Level 2 inspection before the first fire of the season. The repair is flashing replacement and sealant, but the diagnosis requires getting on the roof and looking - not just peering up from the yard.
- Open, uncapped decommissioned flues in triple-deckers. Because Medford’s triple-deckers were converted from oil to gas one unit at a time, Hillside and West Medford chimneys routinely carry an open, uncapped flue whose terra-cotta liner was never installed - pulling river-valley dampness, cold air, and animals straight into the shared masonry and bleeding draft from neighboring active flues. Untangling which flue serves which tenant is the first task on any Medford fireplace job.

FAQs - Fireplace Services in Medford
Check three things: whether the damper opens fully and seats cleanly, whether there’s any visible debris or animal nesting in the firebox, and whether you smell moisture or see staining on the ceiling near the chimney breast. If any of those are present, schedule a Level 2 inspection before lighting the first fire - Medford’s wet winters mean water damage often hides until the heating season starts. Call (857) 392-4709 and we’ll camera the flue, photograph the crown from the roof, and tell you what’s safe to burn and what needs repair first.

Yes, and it matters more than most landlords realize. An uncapped, unlined flue draws cold air and river-valley moisture into the shared masonry, which accelerates mortar deterioration and bleeds draft from neighboring active flues. We’ve traced gas fireplace failures and ceiling stains directly to abandoned flues left open for decades. Capping and sealing is usually a few hundred dollars; leaving it open risks thousands in shared-stack rebuild. Call (857) 392-4709 for an exact quote - estimates are free.

Because the damage is at the crown and upper courses, where freeze-thaw and wind-driven rain attack first, and water travels down inside the brick before it shows at the firebox. Medford’s location in the Mystic valley means more moisture exposure and sharper freeze-thaw cycling than inland communities - chimneys that appear sound from the driveway often show significant water intrusion at the crown and firebox after just a few wet winters. The camera inspection reveals what the eye can’t. Call (857) 392-4709 for a free estimate.

Each tenant’s fireplace and flue is individually inspected and serviced, but the shared masonry and any abandoned flues affect everyone. We audit flue ownership and venting assignments before cleaning - a multi-family coordination problem that rarely arises in single-family markets. If your lease makes you responsible for the fireplace, we’ll inspect your unit’s flue and report on conditions that affect the shared stack. If the landlord handles it, we’ll document what we find for all parties. Either way, you’ll know exactly what you’re burning in. Call (857) 392-4709 to schedule.

Stage 1 creosote - flaky, sooty, brushable - comes off with a standard sweep. Stage 2, the shiny, tar-like glaze that builds from slow, smoldering fires in airtight stoves, requires a rotary loop or chemical treatment. Stage 3, the hardened, ceramic-like deposit, cannot be brushed and may require a liner replacement if it’s thick enough to restrict the flue. We camera every Medford fireplace before we sweep, so we know what we’re dealing with and quote accordingly - no surprises after we’re on site. Call (857) 392-4709 for a free estimate.
