Cracked panels and worn fireplace parts fixed in Colonial Town Center

Firestop spacers at every floor and ceiling

Wherever the chimney passes through a floor or ceiling, one maker's system uses a firestop spacer that holds the required clearance between the pipe and the framing and separates one floor space from the next or from the attic.

A missing, bent or displaced firestop leaves framing closer to the pipe than the listing allows. We check firestops wherever access allows and replace damaged ones with the maker's part.

• A firestop at every floor or ceiling the pipe crosses
• Clearance to framing held
• Damaged firestops replaced with the maker's part

Clearances between the unit and the framing

Zero clearance describes a design, and the design still has clearances. One maker's model lists minimum clearances to combustibles at the back and sides of the fireplace, to the ceiling, in front of the opening and to the outer pipe of the chimney.

Remodels sometimes push framing, backer board or trim tighter than those figures. We compare what we can see with the manual for your model and list any clearance that needs correcting.

• Back and sides of the unit
• Ceiling above it
• Floor space in front of the opening
• Outer pipe of the chimney

Cleaning a round metal flue

The inner flue of a factory-built chimney is thin stainless steel, round and smooth. One maker's troubleshooting advice for a dirty or blocked chimney mentions a properly sized chimney brush, since the brush has to fit the round pipe it cleans.

During a prefab repair we note the condition of the flue and whether deposits are present. Cleaning is scheduled with a brush that fits your flue, and dents or damage found along the way go on the repair list.

What a prefab repair estimate lists

A good estimate for a prefab fireplace repair names the maker, the model and the serial number, then lists each part by its number and description. It separates firebox work, chimney work and any access or finish work.

Ours also notes what was checked and what could not be seen, and it shows upfront pricing on each line. You approve exactly the parts and the work you want.

• Maker, model and serial number
• Each part by number and description
• Firebox, chimney and access work as separate lines
• Anything that could not be seen
