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 Fireplace Services Across Medford
Fireplace services in Medford typically cost $180-$520 depending on the work needed, and most appointments are scheduled within a few business days with a written price delivered before any work begins. Our crews serve Medford from our Boston office, carrying the camera-scan gear and replacement parts needed for the city’s pre-WWII triple-deckers and two-family stacks. If you’re seeing smoke spillage, a stuck damper, or a ceiling stain after last winter’s wind, call (781) 649-9326 and we’ll send a named technician with a text when they’re on the way.
We’ve worked the corridors of Medford long enough to know what shows up in these buildings. The triple-deckers along Boston Avenue, the two-families near Medford Square, the brick rows off Salem Street - they all share the same chimney DNA: a single exterior stack, often three or four flues deep, that started life carrying coal smoke and has been adapted through oil and gas conversions without anyone checking whether the flue still fits the appliance. That’s the call we answer most often here with Chimney Repair in Medford.

Why Level Two Chimney Waltham Is Medford’s Preferred Fireplace Services Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of those have been in Medford’s dense, older housing stock. Our Fireplace Services in Medford are built around the same practice that became Clause 4 of the Haven Standard: a camera down every flue, a photo record on every visit, and a written scope, price, and warranty before anyone touches a tool.
Medford customers find us because they read the three-star reviews - the ones that mention whether we actually showed the photos, whether the price matched the quote, whether the technician explained what was found. We answer our phones live, 24 hours a day, seven days a week. No voicemail, no web form that disappears into a queue. When you book in Medford, you get a background-checked, uniformed technician with a license number you can verify, a text when they’re en route, and a documented record when the job is done.
Our response time to Medford is typically same-week during the shoulder seasons and within a few days during peak burning season. We stock parts from Gelco, Olympia Chimney, and Famco specifically to avoid the delays that come with ordering caps, dampers, or liner sections after the fact.
Our Fireplace Services in Medford

Gas Fireplace Service
Gas fireplace service in Medford runs $220-$380 for a standard cleaning, inspection, and burner adjustment. The real issue we find in these pre-WWII buildings is the flue mismatch: a gas insert venting into a chimney originally sized for a coal furnace or wood fireplace, producing condensation that degrades clay tile and rusts metal connectors. Our camera scan checks the full flue length for deterioration, water staining, and proper sizing against the appliance manufacturer’s specs. If the flue is oversized - common in converted Medford stacks - we document it and quote a liner or direct-vent solution in writing before any modification.

Wood Burning Fireplace
Wood burning fireplace cleaning and inspection in Medford costs $180-$280 for a standard sweep with NFPA 211 Level 2 documentation. The Mystic River valley damp here prolongs moisture exposure in these exterior stacks, which means Class III glazed creosote forms more readily than in drier, higher-elevation suburbs. We classify what we find - Class I brushable, Class II tar-like, Class III glazed and baked-on - and show you the camera footage so you understand whether a standard sweep handles it or if chemical treatment or rotary removal is needed. No guesswork, no upsell without evidence.

Fireplace Insert
Fireplace insert installation in Medford ranges $2,800-$4,500 depending on liner length, appliance model, and whether the existing hearth and surround need modification. The critical step in these multi-unit buildings is confirming which flue serves which appliance. We’ve found inserts vented into boiler flues, shared flues between units, and capped flues that were never properly abandoned. Our Fireplace Services team maps the stack before quoting, so the insert you buy actually vents safely and legally. Every insert job includes a new stainless liner, proper insulation, and a photo record of the full installation under Haven Standard Clause 4.

Damper Repair
Damper repair in Medford costs $180-$340 for a standard throat damper adjustment or replacement, or $420-$680 for a top-sealing damper with cap installation. Dampers in these old Medford stacks are often warped, rusted, or jammed with mortar debris from decades of deterioration. A stuck damper wastes heat, invites downdrafts, and can trap smoke in the firebox. We inspect the damper assembly with the camera, quote the repair in writing, and if the throat damper is beyond saving, we recommend a top-sealing damper that stops rain and animals at the crown while improving energy efficiency.

Firebox Repair
Firebox repair in Medford ranges $650-$1,800 depending on whether we’re patching cracked refractory panels, tuckpointing loose firebrick, or rebuilding a deteriorated masonry box. Water intrusion from failed crowns or flashing - accelerated by Medford’s freeze-thaw cycles - is the usual culprit. We show you the spalling brick, the compromised mortar, or the cracked panel before quoting, and we source replacement materials through our Haven buying network to keep the price honest.

Fireplace Conversion
Converting a wood fireplace to gas in Medford runs $1,800-$3,200 for a direct-vent gas insert with proper liner, or $2,400-$4,000 for a full gas log set with remote and safety pilot. The constraint in these buildings is almost always flue sizing and shared-stack configuration. We won’t spec a conversion without first camera-scanning the full flue and confirming venting capacity against the appliance’s BTU rating and the NFPA 211 tables.

AfterTrusted Brands We Service in Medford
We stock and install parts from Gelco, Olympia Chimney, and Famco - brands we source through the Haven buying network specifically to avoid the markup that comes with special-ordering after a diagnosis. For Medford customers, that means faster turnaround on cap replacements, damper assemblies, and liner sections. We don’t carry every SKU in the truck, but we carry what fails most often in these older stacks: stainless caps with proper overhang for wind-driven rain, top-sealing dampers that seal against downdrafts, and flexible liner kits sized for the converted appliances common in pre-WWII housing.
Common Fireplace Services Problems We See in Medford Homes

- Storm-driven water past failed caps and flashing. Wind off the Mystic River and across the low valley drives rain past cracked or missing chimney caps and degraded flashing at the roofline. The first sign is often a ceiling stain in the upstairs unit, weeks after the storm, while the chimney itself looks fine from the street.
- Freeze-thaw spalling on exposed brick and crumbled crowns. Medford’s valley location traps moisture, and repeated freeze-thaw cycles hit the soft lime mortars in these pre-1940 stacks especially hard. By late February we see crowns reduced to gravel and brick faces flaking off - openings that let water straight into the flue system.
- Multi-flue stacks with one cleaned flue and two untouched. A single stack serving three or four units hides boiler flues, capped but never swept, packed with generations of soot and debris. Cleaning one tenant’s fireplace flue and declaring the chimney safe leaves the real venting problem unaddressed.
- Oversized flues from fuel conversions causing backdraft and condensation. Chimneys built for coal or oil, now venting gas appliances, run too large and too cold. The result is chronic downdraft, moisture accumulation, and accelerated deterioration of whatever liner remains - if there ever was one.

FAQs - Fireplace Services in Medford

Wind-driven rain forces water past a cracked or missing chimney cap and degraded flashing at the roofline, then tracks down the stack interior until it finds a seam or penetration point - often the ceiling of the top-floor unit. In Medford’s dense two- and three-families, that stain appears in a bedroom or front room while the chimney looks intact from the sidewalk. We find the entry point with a camera scan of the flue and a close inspection of the crown, cap, and flashing. Call (781) 649-9326 for an exact quote - estimates are free.

No. A fireplace cleaning covers only the flue serving that specific fireplace or appliance. In Medford’s multi-unit buildings, it’s common for one flue to have been cleaned or relined while adjacent flues - often an old boiler flue, long capped - remain packed with soot and debris. We map the full stack with our camera and quote each flue separately so you know what’s actually been addressed. Call (781) 649-9326 for an exact quote - estimates are free.

Often no. Clay tile in these converted stacks was sized for coal or oil combustion, which runs hotter and produces more draft than a modern gas appliance. The oversized flue cools too quickly, causing condensation that degrades the tile and produces acidic runoff. We camera-scan to check tile condition and measure flue dimensions against the appliance manufacturer’s venting tables. If the flue is oversized or deteriorated, we quote a properly sized stainless liner in writing before any installation proceeds. Call (781) 649-9326 for an exact quote - estimates are free.

Look for three things: water staining or efflorescence (white powder) on the firebox walls, which indicates crown or flashing failure; a damper that opens fully and seats cleanly without wobble or grinding; and debris or animal nesting in the firebox or visible flue opening. Do not light a fire if you smell gas, see cracked firebrick, or suspect obstruction - these require professional inspection. In Medford’s older stacks, what looks like a minor issue often connects to a larger flue or liner problem we find with the camera. Call (781) 649-9326 for an exact quote - estimates are free.

Class I creosote - light, flaky, brushable - handles with a standard sweep. Class II is tar-like and requires more aggressive mechanical removal. Class III is glazed, baked-on, and often needs chemical treatment followed by rotary cleaning. Medford’s Mystic River valley damp and the cooler exterior stacks on these triple-deckers promote Class II and III buildup more readily than drier locations. We classify what we find with the camera, show you the footage, and quote the appropriate removal method in writing before starting. Call (781) 649-9326 for an exact quote - estimates are free.
