Chimney sweep and fireplace cleaning in Johnson Village

A throat damper frozen by soot or rust

A throat damper sits right above the firebox, where heat and deposits hit it hardest. When soot, creosote and a little moisture sit on the pivot for months, the plate can freeze in place, either open or shut.

Forcing the handle seldom helps. It can bend the control rod or crack the frame out of its seat. Our crew frees a stuck damper by cleaning the pivot and frame from below, working the plate gently back and forth as the deposits come loose.

Some dampers free up completely once they are clean. Others move but show rust through the plate or a frame that no longer seals, and those are quoted as damper repair, apart from the sweep. If yours is stuck closed, do not light a fire, and leave the handle alone until our technicians have seen it.

Smoke stains on the face above the opening

Dark staining on the brick, stone or plaster above the fireplace opening means smoke has been rolling out of the top of the opening during use, even briefly. It often starts when a fire is lit with the damper not fully open or when the fireplace draws slowly at startup.

The sweep cleans the flue and firebox, and the face can be cleaned too, but brushing alone does not stop new stains. The cause has to be found. Our crew looks at the damper, the smoke chamber and the flue for anything that holds the smoke back on its way up.

Soft stone and painted brick can be damaged by strong cleaners, so face cleaning is done gently and only when you ask for it. The written record keeps the stain cleanup and the cause as two separate items.

The written record you keep after a sweep

Every sweep ends with a written record of what was cleaned. It notes the date, the fireplace or stove, which flue was swept, the kind of deposits found and the areas the brushes reached.

It also lists what was not done. Glazed sections left for a separate treatment, any part of the flue that could not be reached, and any repair item found during the visual check are written down with the reason. If a section was treated for glaze, the record notes that a follow-up sweep is still due.

Keep the record with your appliance manuals and past repair papers. It helps the next sweep, helps a buyer if you sell, and gives any later technician a starting point instead of a guess.

• Date and system cleaned
• Deposit type before cleaning
• Areas reached and areas not reached
• Findings left for a separate decision

Why creosote in the flue is a fire hazard

Creosote is fuel. EPA guidance describes it as a highly combustible black or brown residue and says that if enough builds up in the chimney it could cause a chimney fire. One chimney maker adds that ignited creosote makes an extremely hot fire.

A fire belongs in the firebox. A thick layer of deposits in the flue gives heat and sparks from below something else to catch, out of sight and above the room. The thicker that layer grows, the more fuel sits waiting in the flue.

Removing the fuel is what a sweep does. Our technicians clear deposits from every surface the brushes reach and tell you plainly if any part of the flue still holds buildup they could not remove. In Johnson Village, a glazed section is quoted for its own removal treatment, and the fireplace is best left cold until that is done.
