We’ve inspected and serviced more than 38,000 chimneys and fireplaces since 2009, and every single job has followed the same sequence: camera down the flue, findings documented in photos, written scope and price delivered before tools come out. Cambridge’s housing stock - heavy on 1890s triple-deckers, 1920s colonials in West Cambridge, and the mid-century ranches off Concord Avenue - presents a narrow but predictable set of fireplace problems. We’ve seen them. We name what we find, show you the photo evidence, and quote the repair in writing. That’s Haven Standard Clause 1: have it in writing. Corrine Halstead built Level Two Chimney Co. on that practice, and we haven’t waived it once in sixteen years.

What Our Fireplace Services Include

Gas Fireplace Service

Gas fireplaces in Cambridge fail in specific ways: thermopiles weaken after 3-5 years of seasonal cycling, pilot assemblies clog with dust from forced-air systems, and vented units develop condensation corrosion in the firebox base. We test gas pressure at the manifold, measure thermopile output in millivolts, and inspect the venting run with a borescope for blockages or joint separation. If your Mendota, Heat & Glo, or Kozy Heat unit won’t stay lit or produces soot on the glass, we’ll diagnose it, name the part, and quote replacement before ordering anything.

Wood Burning Fireplace

Wood burning fireplaces in Cambridge face a genuine maintenance burden: the city enforces EPA Phase II standards for new installations, and older units often lack proper combustion air or have degraded firebrick that exposes surrounding framing. We perform NFPA 211 Level 2 inspections with camera documentation of the smoke chamber and flue liner, measure creosote deposition by class (Class I brushable, Class II tar-like, Class III glazed and ignitable), and evaluate the firebox for spalling or cracked throat dampers. If you’re burning in a pre-1990 unit in Porter Square or a rebuilt hearth in Harvard Square, we can tell you exactly what condition it’s in and what work can wait versus what can’t.

Fireplace Insert

A fireplace insert is a steel or cast-iron firebox that slides into an existing masonry opening, connected to a stainless liner running the full flue height. Cambridge installations often fail at the liner termination - improper anchoring to the insert collar, or a flex liner that snagged on a chimney offset and tore. We inspect the liner connection with a camera, test draft pressure under operating conditions, and verify clearances to combustibles per the insert manufacturer’s listing. If you’re considering an insert for a drafty Cambridge living room, we’ll measure the fireplace opening, check the flue compatibility, and quote the full installation with no surprise masonry charges after we’re in your home.

Damper Repair

The throat damper sits above the firebox and seals the flue when the fireplace isn’t in use. Cambridge’s freeze-thaw cycles warp cast-iron dampers, and the pivot pins corrode in homes within two miles of the Charles where humidity runs higher. A stuck-open damper costs you conditioned air year-round; a stuck-closed damper is a carbon monoxide hazard with any fuel type. We inspect damper operation, measure the frame for square, and repair or replace with a top-sealing damper if the throat mechanism is too deteriorated. We quote both options in writing before work begins.

Firebox Repair

The firebox is the refractory brick or metal chamber that contains combustion. In Cambridge’s older housing, we’ve found cracked rear walls where decades of thermal cycling separated the brick from the surrounding masonry, and rusted metal fireboxes in 1960s prefab units where the factory refractory panel disintegrated. We assess whether cracks are cosmetic (hairline, no through-penetration) or structural (opening to combustible framing), document with photos per Haven Standard Clause 4, and quote panel replacement, refractory relining with HeatShield cerfractory foam, or full firebox rebuild depending on what the camera shows.

Fireplace Conversion

Converting a wood fireplace to gas - or less commonly, gas to wood - requires permit work through the Cambridge Inspectional Services Department, gas line sizing verification, and often a new liner rated for the appliance category. We’ve converted units in Inman Park triple-deckers where gas service was already present and in North Cambridge basements where we had to extend a medium-pressure line. We handle the permit application, coordinate the gas utility lock-tag, and install the appliance with a properly sized and listed venting system. The written quote includes all trades; we don’t subcontract and add markup after you sign.

Brands We Service for Fireplace Services

We’ve serviced and repaired hundreds of Heat & Glo direct-vent units in Cambridge condos and townhomes, particularly the SL-550 and 6000 series common in 2005-2015 construction. We stock OEM pilot assemblies, blower kits, and replacement glass from their current parts network, and we know the venting restrictions that trip up installations in tight mechanical closets. For DuraFlex liner systems, we’ve completed full relines on Cambridge chimneys with multiple offsets, using their corrugated stainless flex rated to 2100°F - the right product when the flue has shifts that rigid pipe can’t navigate.

We also work regularly with HeatShield for firebox restoration and smoke chamber parging, Famco chimney caps and termination fittings, and Copperfield chimney supply hardware for custom fabricated solutions. Whether you have a Mendota, Regency, Napoleon, Jøtul, Vermont Castings, or an unbranded prefab unit from a 1970s ranch, we can inspect it, identify the manufacturer from the rating plate, and source parts through our Haven buying network. If we can’t service it, we’ll tell you before we charge anything.

Signs You Need Fireplace Services Right Now

• Soot buildup on gas fireplace glass. Clean-burning gas should produce almost no particulate. Soot indicates incomplete combustion from a misaligned burner, degraded media placement, or incorrect gas pressure. Left unaddressed, it deposits on the firebox and venting, and it can signal elevated carbon monoxide in the exhaust stream.
• Draft reversal or smoke spillage into the room. If your wood fireplace smokes back on startup or when the kitchen range hood runs, the chimney may be undersized, obstructed, or competing with negative pressure from modern airtight construction. In Cambridge’s densely built neighborhoods, we’ve traced this to blocked flues from deteriorating chimney caps and to house-pressure imbalances from new HVAC equipment.
• Visible cracks in firebox brick or refractory panels. Hairline surface cracks are normal; cracks that penetrate to the metal wrapper or open gaps between bricks are not. They allow heat transfer to combustible framing, and in Cambridge’s balloon-framed triple-deckers, that framing is often continuous from basement to attic.
• Persistent gas odor or pilot light outages. Natural gas odor near the fireplace requires immediate evacuation and utility notification. Intermittent pilot failures - the pilot lights, the main burner fires briefly, then everything shuts down - usually indicate a weak thermopile (below 325mV under load) or a safety switch detecting abnormal conditions.
• Rust stains or water in the firebox. Water entry destroys metal fireboxes and deteriorates refractory brick. In Cambridge, we see this most often where chimney crowns cracked after freeze-thaw cycles, or where flashing failed at the roofline on low-slope porches common in 1920s construction. The water is a symptom; the source is usually above the roofline.

Our Fireplace Services Process - Step by Step

1. 1
   Schedule and confirm. Call (857) 309-1908 and you’ll reach a live person, not a voicemail tree. We confirm your address in Cambridge, the fireplace type and brand if you know it, and the symptom you’re experiencing. We assign a technician and text you when they’re en route with a photo and ETA.
2. 2
   Arrival and protection. Our technician arrives in a marked vehicle, uniformed, with license information visible on request. They lay drop cloths from the entry to the hearth, inspect the visible fireplace and chimney exterior, and ask you to describe the problem in your own words before touching anything.
3. 3
   NFPA 211 Level 2 inspection with camera documentation. We run a chimney camera through the flue to inspect the liner, smoke chamber, and firebox from the inside. For gas units, we test manifold pressure, thermopile output, and safety switch function. Every finding is photographed or video-recorded. Haven Standard Clause 4 requires this documentation on every job; we’ve done it since 2009.
4. 4
   Written findings and price. We show you the photos, name what we found, and explain what it means for safety and function. Then we deliver a written scope, written price, and written warranty before any work begins. No verbal estimates. No “let me check with the office.” Clause 1 of the Haven Standard: have it in writing.
5. 5
   Work, documentation, and follow-up. We complete the approved work, test all functions, clean the work area, and provide a final photo record of the completed repair. You receive a digital copy of all documentation for your records and for any insurance or real estate transaction. The 365-Day Done Right Promise covers the workmanship; if it’s not right, we make it right.
