Chimney sweep and flue cleaning in Callahan

Brushing the smoke chamber above the damper

Above the damper, the smoke chamber funnels smoke from the wide firebox into the narrower flue. Its walls slope inward, and deposits collect on those slopes where a straight flue brush passes them by. A factory-built fireplace has no masonry smoke chamber, and its metal transition above the firebox is cleaned the way its maker directs.

The Florida Building Code calls for the inside of a masonry smoke chamber to be parged smooth with refractory mortar. A smooth surface brushes clean. A rough or stepped surface, with brick edges showing, holds soot on every ledge and takes more work to clean.

Our technicians brush the smoke chamber from below with a brush shaped for its angled walls, then look at the parging once it is visible. Missing or crumbling parging becomes a separate repair item for your Callahan home, while the sweep still cleans what is there.

Smoldering fires and a half-open damper

A slow, smoky fire feels economical, but it is hard on the flue. EPA guidance calls a smoldering fire unsafe and wasteful in most appliances, and it names starved air as one of the conditions that builds creosote.

Air gets restricted in a few familiar ways. The damper is only partly open, glass doors are shut on an open fireplace, the fire is buried under too much wood, or a stove's air control is turned all the way down for a long burn. Each one slows the smoke and lets it cool.

Hot, bright fires with the damper fully open move smoke up the chimney quickly, so less of it condenses on the way. When our crew sees heavy buildup, they point to the habit that likely caused it so the next sweep finds less.

Dry, split, seasoned wood stored off the ground

Wet wood burns smoky, and EPA guidance links unseasoned wood directly to creosote buildup, since the fire spends its energy driving off water and makes more smoke doing it. The guidance is plain. Burn only dry, split, well-seasoned wood, and skip anything wet, rotted or moldy.

Seasoned wood is darker, weighs less and sounds hollow when two pieces are knocked together, according to the same guidance, which calls for seasoning wood at least six months. Stack it outdoors, off the ground, with only the top covered, because covering the sides traps moisture.

From the deposits, our technicians can often tell whether the wood has been wet, and they will say so.

• Split, dry and seasoned before it burns
• Stacked outdoors and off the ground
• Covered on top only
• Checked for mold or rot before use

Chimney sweep and inspection in one visit

Many homeowners ask for a chimney sweep and inspection together, and that is how our visits usually run. Our technicians do the free inspection first to see what is in the flue and what shape the system is in, then sweep if cleaning is needed.

The two parts answer different questions. The sweep removes deposits. The inspection looks at the condition of the chimney and fireplace, including parts a sweep never touches, such as the crown, the flashing and the outside masonry. When you need a formal chimney evaluation, for a sale or after damage, that is a separate chimney inspection service.

In Callahan, the result is one appointment, one written estimate with the sweep and any repairs on separate lines, and a record of what was cleaned and what was seen.
