Chimney Sweeping in Boston, MA — Same-Day Appointments Open Today

It comes down to how hard you run the thing. A Back Bay fireplace lit a dozen times over the holidays is a different animal than a triple-decker woodstove burning nightly from late October through early April, and the heavy user needs a sweep every season while the occasional user can often stretch it. Burning unseasoned wood or damping down low builds creosote faster than anything else. If you cannot remember the last sweep, that alone is reason enough to book one.

We start at the fireplace with drop cloths down, then check the firebox, damper, smoke chamber and the first stretch of flue. The sweeping itself runs brushes and rods through the flue with a vacuum pulling the whole time, and we scope the liner afterward to see what the brushes left behind. Then we look at the crown, cap and exterior masonry, since freeze-thaw cycling is what opens joints on Boston chimneys. You get told what we found and what, if anything, needs attention.

A standard sweep and inspection usually runs about an hour, longer on a tall downtown flue or if the system has not been touched in years. Mess is the thing people worry about and it is the thing we plan around first: floor coverings, a sealed vacuum at the opening, and tools handled so soot stays in the flue. Rowhouse hallways and narrow Beacon Hill stairs get extra covering. You should not be cleaning up after us.

Smoke rolling back into the room, a draft that refuses to establish no matter how you light it, or a sour campfire smell on a humid August day all point at something in the flue. Birds nesting, leaves and twigs dropping into the firebox, or a cap that went missing after a nor'easter mean the chimney is open to the weather. Falling grit, staining on the wall above the mantel, or a damper that will not move are also worth a call. Any of these, stop using the fireplace until someone looks.

Height and access matter most in Boston. A three-story Federal brick rowhouse with a steep slate roof and no safe ladder setup takes longer than a postwar cape in the outer suburbs. Heavy creosote buildup from years of use means a second pass, and an offset flue or a chimney serving two appliances adds time. Estimates are free, and you will know the number before anyone starts.

Yes, just not for the same reasons. There is no creosote, but pilot assemblies drift out of adjustment, burner ports clog, logs get moved out of position and the glass hazes over, and we service Heatilator, Heat & Glo, Majestic, Napoleon, Superior and Empire units, including the factory-built metal fireboxes common in condo conversions and infill builds. The vent run gets checked too, since salt spray and wind-driven rain off Boston Harbor are hard on terminations. Same-day slots exist, though November through March they go early, so call in the morning.
