Chimney Sweep in Somerville, MA

That's the most common call we get in Somerville, and the honest answer depends on what the inspection finds inside the stack. On an 1880s–1920s two-family or triple-decker, a small masonry firebox with sound brickwork and a straight, unshared flue is usually worth bringing back: clean it, repair the crown and cap, and it works. If the flue is cracked, cross-connected with another unit, or already converted to gas logs downstairs, relining can be the bigger job. Plenty of owners here decide to keep the mantel as decoration and properly cap and seal the flue instead, which is a legitimate outcome, not a failure. We'll tell you which side of that line your chimney falls on before you commit to anything.

They change the scope. In subdivided Somerville buildings, flues often run side by side in one stack, and over a century of conversions it's not unusual to find two appliances or fireplaces tied into the same flue, or a breach between adjacent flues in the shared masonry. That's where spillage and smoke showing up in a neighbor's unit comes from. We check which flue actually serves your fireplace or heater before we clean, because the appliance you think you're sweeping and the flue you're actually in aren't always the same. If the building has multiple owners, it's worth coordinating so the whole stack gets looked at once rather than one unit at a time.

Access does more to the number here than anything else. Narrow setbacks between buildings and steep triple-decker roofs mean crown, cap and flashing work is often a ladder-and-staging problem before it's a masonry problem, and that's where the labor goes. A straightforward interior sweep on a single small fireplace is at the simpler end. Costs climb when there are multiple flues in one stack, when an idle flue has taken on water and the crown needs attention, or when a condo conversion left undocumented work inside the chimney that has to be sorted out. We'd rather walk the roofline and look inside first than guess from the curb.

Water and nesting, more than creosote. So many flues in Somerville sit idle behind a sealed-off or decorative mantel, and an unused flue with a failing crown or a missing cap takes on rain year after year, which spalls brick and rusts out dampers from the inside. Birds and squirrels get into uncapped idle flues regularly. The other recurring find is a gas log conversion done during a condo renovation without the venting being checked, or an old oil or gas heating flue that was never relined when the appliance changed. Heavy creosote buildup really is the exception in a city where most fireplaces see light use.

Routine sweeps and inspections are usually booked within a reasonable window, and that window gets longer through the fall as everyone schedules before the heating season. Same-day is sometimes possible, especially if you're near other Somerville or Davis-area work already on the calendar that day, but we won't promise it blind. If you have smoke coming back into the unit, a smell of flue gas, or an animal in the chimney, say so when you call and we'll treat it as urgent rather than routine. Parking is tight on most of these streets, so we'll ask ahead of time where the truck can sit.
