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 Fireplace Services in Medford
Gas Fireplace Service
Gas fireplaces in Medford’s older homes often struggle because they’re venting into flues engineered for coal. The orifice is right, the burner is clean, but the draft is weak because the flue is three times too large. We service gas units throughout Medford, from inserts in renovated Tufts-area condos to original conversions in West Medford Victorians. Our techs check gas pressure, clean burner ports, inspect the pilot assembly, and verify venting with a Level-2 camera inspection. If the flue is oversized, we’ll recommend a properly sized DuraFlex liner - documented with photos, explained in plain English.

Wood Burning Fireplace
Wood burning in Medford means dealing with dense neighborhood housing and strict burning regulations. We sweep and inspect wood-burning fireplaces across the city, paying special attention to creosote buildup in the oversized flues common to pre-1940 construction. First-degree creosote condenses fast when the flue is too large and runs too cool - a pattern we see constantly in Medford’s triple-deckers. We remove the buildup, inspect the firebox and smoke chamber, and give you a written condition report. If you’re burning regularly through Medford’s heating season, an annual sweep is not conservative - it’s necessary.

Fireplace Insert Installation
A fireplace insert is often the right fix for a Medford homeowner with a beautiful but inefficient masonry fireplace. Inserts seal the combustion zone, draw air from outside, and put usable heat into the room instead of up the chimney. We size and install inserts for Medford’s varied fireplace openings, from the shallow Rumfords in some West Medford homes to the deep, wide boxes common in South Medford triple-deckers. Every installation includes a properly sized flue liner - usually DuraFlex or HeatShield - because venting an insert into an existing oversized flue is a code violation and a safety hazard.

Damper Repair
A failed damper costs you money every night it’s left open - heated air escapes, cold air drops in, and your boiler works harder. In Medford’s older homes, we see throat dampers rusted solid from decades of river-valley humidity, top-sealing dampers with corroded cables, and cast-iron frames cracked from thermal cycling. We repair what can be repaired and replace what can’t, often with a lock-top damper from Olympia Chimney or Famco that seals at the flue top and eliminates the deteriorated throat assembly entirely. Most damper work is done in one visit.

Firebox Repair
The firebox takes the direct heat, and in Medford’s 1885-1940 housing stock, the refractory panels or firebrick are often original and deteriorated. Cracked panels, missing mortar, and spalled brick let heat reach combustible framing - a genuine fire hazard. We repair fireboxes with HeatShield refractory restoration or panel replacement, matching the repair method to the damage we document during camera inspection. No recommendation without photo evidence you can see for yourself.

Fireplace Conversion
Converting a wood-burning fireplace to gas is popular in Medford, especially among homeowners tired of hauling wood and dealing with ash in tight urban lots. But conversion is not a burner swap - it’s an engineered venting solution. We handle the gas line coordination, install the burner and log set, and most critically, resize the flue with a DuraFlex stainless liner matched to the new appliance’s BTU output and venting category. An unlined or oversized flue venting a gas insert is a carbon monoxide risk. We don’t let a conversion leave our hands until the draft tests pass and the camera inspection confirms clear venting.

Trusted Brands We Service in Medford
We stock parts and materials from Gelco, Olympia Chimney, Famco, and Copperfield - professional-grade brands, no builder-grade substitutes. For Medford customers, that means faster turnaround. When a storm off the Mystic displaces your chimney cap or cracks your crown, we don’t order parts from a warehouse three states away. We carry common cap sizes, damper assemblies, and flashing stock on our trucks. If your two-family on Salem Street needs a custom Gelco cap or your Riverside Avenue chimney needs Famco counter-flashing, we source it fast and install it right. Done right - and we stand behind it.
Common Fireplace Services Problems We See in Medford Homes
- Storm-displaced caps and flashing failure. Wind off the Mystic River drives rain into chimney caps and lifts flashing at the roofline. The leak shows up weeks later as a brown ceiling stain or efflorescence bloom on the chimney breast. Homeowners often call a roofer first; the real fix is chimney-specific counter-flashing and a properly secured cap.
- Cracked crowns on pre-1940 masonry. Medford’s river-valley humidity accelerates mortar-joint deterioration so aggressively that chimney crowns and joints here often need repointing in 10-12 years - roughly half the lifespan they’d get in drier upland suburbs like Winchester or Woburn. The crown crack is the entry point; the spalled brick and failed joints are the result.
- Oversized, unlined coal-era flues venting modern appliances. Medford’s housing boom packed the city with triple-deckers whose chimneys were engineered for coal, then converted to oil or gas. Those flues are too large for modern appliances, producing weak draft, accelerated creosote condensation, and eventual liner failure. We regularly find gas appliances venting into unlined masonry with almost no draft - a carbon monoxide risk that camera inspection reveals.
- Failed dampers in multi-flue chimneys. Triple-deckers and two-families often have one chimney serving multiple units. The damper in the second-floor unit seizes open, the first-floor tenant gets smoke spillage, and nobody knows who’s responsible for repair. We sort out the flue assignment, document each damper’s condition, and quote repair by unit so landlords and tenants have clarity.

FAQs - Fireplace Services in Medford
Medford’s Mystic River valley location means significantly higher ground-level humidity than Burlington’s drier upland position, and that moisture accelerates mortar-joint deterioration and crown freeze-thaw cycling. A crown that might last 20 years in Burlington often needs repointing or replacement in 10-12 years here. We regularly recommend water-repellent treatment on Medford crowns as a preventive measure - it extends service life by reducing moisture absorption into the masonry. Call (781) 905-8338 for an exact quote - estimates are free.

It’s usually both, and we won’t know until we inspect. Wind off the Mystic displaces caps and drives rain behind flashing; a cracked crown then lets that water migrate into the masonry and show up as a ceiling stain. We got called to a two-family on Riverside Avenue after the owner spotted exactly this pattern - storm-displaced cap, failed flashing driven loose by wind, cracked crown letting water straight in. Our tech pulled a Level-2 inspection, reset the flashing with new counter-flashing, poured a new crown, and dropped in a DuraFlex stainless flue liner. Two weeks later the stain had stopped spreading. Call (781) 905-8338 - we’ll diagnose it with photos you can see.

Each flue is cleaned and inspected separately, and each unit’s landlord or owner is responsible for their own flue’s condition unless a written agreement states otherwise. We document each flue assignment during inspection - critical in Medford’s dense multi-family housing - and provide separate condition reports and quotes by unit. If a common element like the crown or exterior flashing fails, responsibility may be shared; our plain-English verdict helps you present clear documentation to co-owners or tenants. Call (781) 905-8338 to schedule - estimates are free.

Yes, especially in Medford. River-valley humidity deteriorates masonry and metal components whether you burn or not. We’ve found cracked crowns, failed dampers, and animal nests in chimneys that sat unused for full seasons. An annual Level-2 inspection catches deterioration before it becomes a safety issue - carbon monoxide risk from a blocked or damaged flue doesn’t care how often you lit a fire. The $89 Seasonal Tune-Up is the economical way to stay current. Call (781) 905-8338 to book.

It matters significantly. An oversized flue venting a gas appliance produces weak draft, incomplete combustion, and potential carbon monoxide spillage into living space. Medford’s 1885-1940 housing stock is full of coal-era flues now serving gas inserts they were never designed for. We size and install a DuraFlex stainless liner matched to your insert’s specifications - documented with camera inspection before and after, draft-tested, and explained in plain English. Nothing is recommended without photo evidence you can see for yourself. Call (781) 905-8338 for an exact quote - estimates are free.
