"Dorian’s crew removed a years-old creosote glaze that other sweeps missed. The video inspection proved it—now my fireplace drafts perfectly and I finally trust my carbon monoxide detector again."
"They installed a copper cap on my 1920s bow-front in under an hour. No mess, no noise, and the squirrels haven’t been back. Worth every penny to protect my historic home."
"After a chimney fire scare, Dorian came the same day and found a blocked flue from a fallen brick. Their emergency service saved my season—and my insurance premium."
"I’ve had three sweeps in five years; Dorian is the only one who explained why my damper wasn’t sealing properly. Fixed it on the spot and my heating bills dropped 12%."
"The masonry repair on my brick veneer stopped the water stains in the living room. They waterproofed without painting over the historic brick—exactly what I needed for my Cambridge landmark."
"Called at 7 PM for a weekend appointment; they showed up at 9 AM sharp. The crew was polite, efficient, and left my condo’s shared chimney cleaner than I’ve ever seen it. Highly recommend."

That campfire stench is trapped moisture and creosote reacting with Cambridge’s humid air. A thorough sweep removes the buildup, but we also check for leaks or missing flue tiles that let water in. Once the system’s dry and clean, the smell fades—no air fresheners needed.
Cambridge’s mix of older homes, higher humidity, and frequent temperature swings accelerates soot and creosote formation. Older masonry or unlined flues also trap more residue. We’ll inspect your setup and adjust your maintenance schedule accordingly.
Burning wet wood in Cambridge’s damp climate creates more smoke, creosote, and wasted energy. Dry, seasoned hardwood burns hotter and cleaner—saving you money and reducing flue buildup. We’ll point you to local suppliers who stock properly dried wood.
That white stain is efflorescence, a sign water’s leaching through your masonry. It’s not just cosmetic; trapped moisture rots bricks and rusts metal components. We’ll seal the flue and repair any cracks to stop the damage in its tracks.
Massachusetts requires a Level 2 inspection for home sales, especially if your chimney’s over 20 years old or shows damage. We’ll scope the flue, check for hidden hazards, and provide a CSIA-certified report—no surprises at closing.
A whistling chimney usually means a blockage or improperly sized flue cap. East winds in Cambridge can force air down the flue, creating that noise. We’ll clear obstructions and install a wind-resistant cap to quiet it for good.
No. Fogged glass means combustion gases aren’t drafting properly, often due to a dirty flue or blocked damper. We’ll clean the system and adjust airflow so your glass stays clear and your air stays safe.
DIY chimney cleaning in Cambridge rentals is risky—liability falls on you if something goes wrong. Plus, improper tools can damage the flue. We handle rentals the same way we do owner-occupied homes: safely, legally, and to code.
