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.

We’ve worked on fireplaces in Harvard Square Victorians, Mid-Cambridge triple-deckers, and the brick colonials off Brattle Street. Cambridge’s freeze-thaw cycles are hard on masonry, and the older housing stock means we regularly see dampers that haven’t sealed properly since the 1980s and fireboxes cracked by decades of thermal stress. Russell Haines started this company in 1984 because he believed homeowners deserved a square deal: photos they could see, a plain-English verdict, and a written promise that the work would be done right. That hasn’t changed in 42 years.

What Our Fireplace Services Include
Gas Fireplace Service
Gas fireplaces in Cambridge need annual service to keep burners clean, pilot assemblies functioning, and ventilation paths clear. When soot builds up on ceramic logs or the thermopile weakens, you get weak flames, odd odors, or a unit that won’t stay lit. We disassemble the firebox, clean the burner ports with compressed air and hand tools, test the gas pressure with a manometer, and inspect the venting with a flexible camera. Most gas fireplace service calls in Cambridge take 90 minutes and are done in one visit.
Wood Burning Fireplace
A wood burning fireplace in Cambridge requires more than aesthetic appeal; it needs a sound firebox, a working damper, and a flue that draws properly. We often find in North Cambridge and Porter Square homes that the throat damper has rusted open, sending heated air up the chimney all winter. Our Level-2 camera inspection documents the condition of the firebox, smoke chamber, and flue liner, and we provide photos with a plain-English verdict on what needs attention now versus what can wait.
Fireplace Insert
A fireplace insert converts an inefficient open hearth into a sealed, high-efficiency heating system. In Cambridge’s older homes, we size inserts carefully because the existing fireplace opening may not meet modern clearance requirements. We measure the firebox, check the chimney liner compatibility, and install inserts from major manufacturers using DuraFlex and Olympia Chimney components for the venting system. Most insert installations in Cambridge are completed in one day, with the old damper removed or bypassed and a new stainless steel liner dropped from the top.
Damper Repair
The damper is the metal plate that seals your fireplace from the chimney when not in use. A damper that won’t open fully means smoke in your living room; one that won’t close means you’re heating the outdoors. In Cambridge, we replace throat dampers with top-sealing dampers from Famco when the original is too corroded to repair, and we rebuild the damper frame with firebrick and refractory mortar when the surrounding masonry has degraded. We always test the seal with a smoke pencil so you can see it work.
Firebox Repair
The firebox is where the fire actually burns, and its refractory panels or brick lining take the full force of the heat. Cracked fireboxes in Cambridge are common in homes built before 1950, where the original firebrick has spalled or the mortar joints have turned to powder. We repair fireboxes with HeatShield refractory coating or replace panels with matching refractory brick, and we never recommend a rebuild when a repair will last. Our 90-Day Done Right Promise covers every firebox repair in writing.
Fireplace Conversion
Converting a wood burning fireplace to gas, or vice versa, requires more than swapping components. In Cambridge, gas conversions need a licensed plumber for the gas line, proper venting for the new appliance type, and often a new chimney liner. We handle the full project, coordinate permits when required, and use Gelco and Copperfield components for the venting and termination. We also convert gas fireplaces back to wood when homeowners want the original character restored, which is more common in the historic districts near Harvard and MIT.
Brands We Service for Fireplace Services
We’ve serviced hundreds of HeatShield refractory systems and stock their ceramic coating materials for firebox repairs. HeatShield’s cerfractory technology bonds to damaged brick and creates a smooth, heat-resistant surface that lasts for years. We’ve applied it in Cambridge homes from Inman Square to West Cambridge, and we photograph every application for the homeowner’s records.
We also work extensively with DuraFlex stainless steel liners and Olympia Chimney components for insert installations and relining projects. DuraFlex’s corrugated design flexes through offset flues without losing draft performance, which matters in Cambridge’s older chimneys that weren’t built straight. Whether you have a HeatShield-lined firebox, a DuraFlex-vented insert, or any other make, we can help. Our trucks carry common parts for major brands, and we source OEM components for everything else.
Signs You Need Fireplace Services Right Now
- Smoke entering your living room. This means your chimney isn’t drafting properly, which could be a blocked flue, a stuck damper, or negative air pressure from modern weatherization. In Cambridge’s tight older homes, we’ve seen kitchen exhaust fans and dryer vents pull smoke back down the chimney.
- Cracks or gaps in the firebox walls. Heat and combustion gases can escape through cracks into the wall cavity, creating a real fire hazard. We inspect every crack with a camera to determine if it’s surface spalling or a through-crack that needs immediate repair.
- A gas fireplace that won’t stay lit or burns with a weak yellow flame. This points to a dirty burner, a failing thermopile, or improper gas pressure. We test with a manometer and clean every orifice by hand rather than blowing compressed air through and calling it done.
- Water stains on the ceiling near the chimney breast. Water in Cambridge often enters through a cracked chimney crown or missing cap, but it can also mean the fireplace flashing has failed. We trace the leak with a hose test and camera inspection before recommending any repair.
- An insert that rattles, backdrafts, or fails to heat the room. Poor insert performance usually traces to an undersized or damaged liner, improper installation clearances, or a blower motor that’s clogged with dust. We diagnose with a draft gauge and temperature readings at the face and top of the unit.

How Much Does Fireplace Services Cost in Cambridge?
If you’re wondering how much Fireplace Services costs, a typical gas fireplace service in Cambridge runs $150-$280 for cleaning, testing, and adjustment. A seasonal tune-up, which includes inspection and minor maintenance, is $89. Damper repair ranges from $350-$750 depending on whether we can rebuild the existing throat damper or need to install a top-sealing replacement. Firebox repair with HeatShield coating typically costs $800-$1,400, while panel replacement runs $1,200-$2,200. Fireplace insert installation, including the liner and termination, generally falls between $2,200-$3,800. Full firebox rebuilds in Cambridge’s historic homes start around $2,400 and can reach $4,500 if the surrounding masonry requires extensive repair.
Several factors affect what you’ll pay. Access matters: a third-floor fireplace in a Cambridge condo with no elevator takes more time than a first-floor hearth in a single-family. The condition of the existing chimney liner affects insert installations, since a damaged liner must be replaced before the insert is vented. Permit requirements vary by work type and location within Cambridge, and we handle all permit applications as part of our service.

We provide itemized estimates with no hidden charges, and our Free Second Opinion offer means you can show us any competitor’s written estimate and we’ll review it honestly.
