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.
Chimney Cleaning in Medford, MA
Chimney cleaning in Medford, MA typically runs $189 to $329 for a standard sweep with a Level 1 inspection, and most jobs are completed in 60 to 90 minutes. What makes Medford different is the housing stock: late-19th and early-20th century two- and three-family homes where one masonry chimney often carries multiple flues, meaning a cleaning is rarely just about one fireplace. Call (980) 580-8641 for a written quote before any work begins.
Why Medford Homes Are Different
Medford’s chimney conditions are shaped by three things: age, shared flues, and the Mystic River valley climate. The vast majority of residential buildings here date from roughly 1885 to 1940, with original unlined or clay-tile-lined masonry chimneys that predate NFPA 211 standards. Many of these chimneys were built to vent coal or oil-fired equipment, then adapted for gas in the 1980s through the 2000s, leaving oversized or abandoned furnace flues inside active chimneys. That creates draft problems, moisture traps, and code violations that surface during what owners expect to be a simple sweep.
The shared-flue dynamic matters more here than almost anywhere else in the metro area. In Medford’s triple-deckers along Boston Avenue and Riverside Avenue, we regularly open a cleanout door and find three or four flues sharing one chase, with 1920s clay tile liners partially collapsed and layered with decades of creosote from both wood fires and old oil soot. One tenant’s neglected buildup becomes a carbon monoxide hazard for every unit in the building.
Add the local climate: Medford sits in the Mystic River valley, a frost-pocket microclimate with elevated overnight humidity. The region sees more than 100 freeze-thaw cycles a year, and that persistent moisture saturates aging mortar joints. Spalling brick, crown cracking, and liner deterioration are measurably worse here than on higher ground in neighboring Stoneham or Malden.
Our Main Medford Services
Medford homeowners call us most about two things beyond cleaning: fireplace performance and the caps and crowns that keep water out of aging masonry. Both are covered in detail on their own pages.
Fireplace Services in Medford
Older Medford fireplaces often draft poorly because the original flue was sized for coal, not a modern wood fire. We inspect the smoke chamber, damper, and flue connection, then recommend the smallest fix that restores draft and safe operation. Full details, including what a fireplace inspection covers and what repairs cost in Medford, are on the Fireplace Services in Medford page.

Chimney Cap & Crown in Medford
A cracked crown or missing cap on a Medford chimney means water gets into the flue every time it rains, and the Mystic River valley humidity keeps that moisture in place. We install or repair both, and in this climate the difference between a good crown and a failing one is often a chimney that lasts 30 years versus one that needs rebuilding in 10. See the Chimney Cap & Crown in Medford page for specifics.

AfterChimney Cleaning & Sweep in Medford

A standard chimney sweep in Medford involves removing creosote and soot from the flue, smoke chamber, and firebox, then documenting what we found with a camera. In Medford’s 1885-1940 housing stock, we’re often cleaning flues that were built before NFPA 211 existed, and the shared-chase arrangement in triple-deckers means one flue’s condition affects every unit in the building. This is the work we describe on our Chimney Cleaning & Sweep hub, applied to the specific conditions we see in Medford.
Level 1 Inspection
Signs you need it
You burn wood or pellets more than a few times a season, or you’ve just moved into a Medford home and have no record of the last cleaning.
What it costs in Medford
A Level 1 inspection runs $189 to $229 when paired with a standard sweep.
How we do it
We inspect the accessible portions of the flue, firebox, and exterior, document everything with photos, and give you a written condition report.
Creosote Removal
Signs you need it
Shiny, tar-like buildup is visible on the flue walls, or your fireplace smells like asphalt on humid Medford summer days.
What it costs in Medford
Creosote removal runs $229 to $389 depending on the class of buildup and flue length.
How we do it
We use rotary loops and chemical treatment appropriate to the creosote class, then camera-verify the flue is fully clear.
Annual Sweep
Signs you need it
It’s been more than 12 months since the last cleaning, or you notice soot falling into the firebox.
What it costs in Medford
An annual sweep runs $189 to $259 for a single flue, including the Level 1 inspection.
How we do it
We run brushes and vacuum equipment through the flue, clean the smoke chamber and firebox, and leave a photo record of the interior.
What Chimney Cleaning & Sweep Costs in Medford
| Item | Typical range in Medford |
|---|---|
| Standard sweep with Level 1 inspection | $189 - $259 |
| Creosote removal (Stage 2-3 buildup) | $229 - $389 |
| Level 2 camera inspection (add-on) | $169 - $249 |
How often should a chimney be cleaned in Medford?
Every year if you burn wood, and at least every two years for gas or oil appliances. Medford’s shared-flue triple-deckers may need more frequent attention because multiple units’ buildup accumulates in one chase. Call (980) 580-8641 to schedule with a written quote first.
What if the inspection finds a collapsed liner during my cleaning?
We stop the sweep, show you the camera footage, and give you a written scope and price for relining. You decide before any additional work starts. That’s Clause 1 of the Haven Standard, and it applies to every Medford job.
Chimney Repair in Medford

Chimney repair in Medford usually means addressing freeze-thaw damage to masonry and the flashing where the chimney meets the roof. The Mystic River valley’s 100+ annual freeze-thaw cycles saturate mortar joints and brick faces, then the water expands and pops them apart, a cycle that accelerates spalling and crown cracking in homes built from 1885 to 1940. We describe the full range of Chimney Repair work on our hub, and what follows is the Medford-specific picture.
Mortar Repointing
Signs you need it
Mortar joints are crumbling, missing, or recessed more than a quarter-inch, and you can rake them out with a finger.
What it costs in Medford
Repointing runs $18 to $30 per square foot of brick face, depending on access and joint condition.
How we do it
We grind out deteriorated mortar, pack in fresh mortar matched to the original strength of the brick, and document the work with photos.
Flashing Repair
Signs you need it
Water stains appear on the ceiling near the chimney after rain, or you can see rusted, lifted, or missing flashing at the roofline.
What it costs in Medford
Flashing repair runs $450 to $950, depending on the number of sides and whether the existing flashing can be reused.
How we do it
We remove or reset the flashing around the chimney base, install step and counter flashing, and seal all transitions with durable sealant.
Chimney Waterproofing
Signs you need it
Your chimney absorbs water visibly after rain, or you have efflorescence, a white chalky deposit on the brick.
What it costs in Medford
Chimney waterproofing runs $450 to $750 for a typical single-family chimney in Medford.
How we do it
We clean the brick, apply a vapor-permeable water repellent, and ensure the crown and cap are directing water away from the flue.
What Chimney Repair Costs in Medford
| Item | Typical range in Medford |
|---|---|
| Mortar repointing | $18 - $30 per sq ft |
| Flashing repair | $450 - $950 |
| Chimney waterproofing | $450 - $750 |
Do I need to repoint before I can use my fireplace again?
Sometimes. If the mortar joints have failed badly enough that water is entering the flue or the brick is shifting, yes. We’ll show you photos and tell you plainly if it can wait. Call (980) 580-8641 for a written condition report.
Why does my Medford chimney spall worse than my neighbor’s in Stoneham?
The Mystic River valley keeps overnight humidity elevated, and those freeze-thaw cycles hit lower-elevation Medford harder than higher ground. Older bricks with softer firing also absorb more water. The fix starts with repointing and waterproofing.
Chimney Liner & Rebuild in Medford

Chimney liner and rebuild work in Medford usually starts with a camera inspection that reveals collapsed clay tiles or an unlined flue that cannot safely vent a modern gas or wood appliance. In the triple-deckers along Boston Avenue and Riverside Avenue, we frequently find 1920s clay tile liners partially collapsed and mixed with decades of layered creosote from wood and old oil soot, a condition that jams inspection cameras and triggers an immediate relining requirement under the current Massachusetts State Building Code. This is the full scope of our Chimney Liner & Rebuild work, applied to Medford’s specific conditions.
Stainless Steel Liner
Signs you need it
Your flue is unlined or the existing clay tile liner is cracked, and you are venting a gas or oil appliance that requires a properly sized liner.
What it costs in Medford
Stainless steel liner installation runs $2,100 to $3,200, including the liner, insulation, and top plate.
How we do it
We size the liner to the appliance, feed it down the existing flue, insulate it, and document the completed install with camera footage.
Liner Replacement
Signs you need it
The existing liner has visible gaps, spalling tiles, or you’ve been told by a gas company or inspector that the flue fails a pressure test.
What it costs in Medford
Liner replacement runs $2,100 to $3,200 for a standard single-family home chimney.
How we do it
We remove the failed liner where possible, install a new stainless steel or cast-in-place liner, and verify the install with a post-installation camera scan.
Full Chimney Rebuild
Signs you need it
The chimney is leaning, bricks are falling, or the crown and top courses have failed so completely that patching would be unsafe.
What it costs in Medford
A full rebuild from the roofline up runs $7,000 to $15,000 or more depending on the height and whether scaffolding is required.
How we do it
We dismantle the chimney to the roofline, rebuild with new brick and mortar, install a new crown and cap, and provide a photo record at each stage.
What Chimney Liner & Rebuild Costs in Medford
| Item | Typical range in Medford |
|---|---|
| Stainless steel liner installation | $2,100 - $3,200 |
| Liner replacement (existing failed liner) | $2,100 - $3,200 |
| Full chimney rebuild | $7,000 - $15,000+ |
Do I really need a new liner, or is the sweep company upselling me?
You should never be told you need a liner without seeing camera footage of the failed one. We show you the video, explain what you’re looking at, and give you a written scope and price before any work is approved. If you have a written estimate from another company, bring it and we’ll give you a free second opinion. Call (980) 580-8641.
Can I reline just one flue in a multi-family Medford chimney?
Yes. Each flue is a separate channel, and only the one serving the problematic appliance needs attention. We’ll document the condition of the other flues and tell you if they can wait or need attention soon.
