Chimney sweep in Lake Pickett with written pricing first

The return visit after a glazed-deposit treatment

A glazed treatment is a two-part job. Once applied, it has to dry in the flue before anything else happens, and the label recommends keeping rain off it while it dries. Some of the dried material drops on its own onto the smoke shelf and into the firebox. The rest comes down with a normal sweep on the return visit.

Very heavy glazed deposits may need a second application before the flue is clean. The label also calls for the cleaned lining to be checked for cracked tile and damaged mortar joints before the fireplace goes back into use, since a thick coating can hide both.

Both visits are scheduled when you approve the work, and we ask you to leave the fireplace unused in between. After the final sweep you get the lining findings in writing.

Why chemical sprays do not replace brushing

Chimney cleaning sprays and powders are sold with the promise of loosening creosote. Some can change how a deposit behaves, but none of them carry it out of the flue. Mechanical brushing is still what removes the material, and whatever a product loosens still has to be brushed down and carried out.

Manufacturer instructions are cautious about chemicals. One maker of metal chimneys says to use chemical cleaners only as a last resort, and only products whose manufacturer specifically warrants them as non-corrosive to the chimney. A spray that is harmless on clay tile may not be harmless on a stainless system.

Our crew brushes first. Where a glazed deposit calls for a chemical treatment, we use one made for that job, apply it per its label, check it against the chimney maker's instructions and list it on your estimate as a separate line.

Brushing a flue that bends or offsets

Not every flue runs straight. Masonry chimneys sometimes shift sideways to clear a roofline or a second fireplace, and factory-built chimneys use elbow sections to route around framing. The Florida Building Code limits how far a clay flue lining may slope from vertical, so masonry bends are gentle, but they are still bends.

A stiff rod and brush can skip across the outside of a bend and miss the inside corner. Our technicians use flexible rods for offsets and work the brush through the bend from both ends when both can be reached.

Offsets also hide things. Debris can lodge in the bend, and the visual check can see only so far past it. For a flue with an offset, the written record notes what could be seen and what could not.

How a sweep visit runs from start to finish

A sweep from our local family-owned team follows the same order every time. The crew arrives, walks the path to the fireplace with you and asks how it has been used. The free inspection comes next, then a written estimate you approve before anything is cleaned. The order stays the same for a small job or a large one.

Before leaving, our technicians go over the written record with you, including anything found that needs a separate decision, and show you the damper's open and closed positions. Questions about the record get answered on the spot in Lake Pickett, before the crew packs up.

• Room protected and the fireplace opening sealed
• Flue brushed from the roof or from inside
• Smoke chamber, smoke shelf, damper and firebox cleaned
• Debris bagged and carried out, then the visual check
