Factory-built fireplaces repaired with listed parts in Southport

When a cracked panel needs replacing

Makers set their own limits for when a cracked refractory panel should be replaced, and those limits live in the owner's manual for each model. A panel that has lost pieces, crumbles at the edges or leaves steel showing behind it is past any reasonable limit.

We read your model's guidance, look at every panel and tell you which ones need replacement now and which can be watched. The estimate names each panel by its position and its part number.

• Pieces missing from the panel
• Crumbling edges
• Steel visible behind the panel
• Cracks wider than the manual allows

Brick-pattern panels and what sits behind them

Many factory-built fireplaces use refractory panels molded with a brick pattern. From the room they can pass for a masonry firebox, while the fireplace behind them is a steel assembly with a listed chimney.

That difference changes the repair completely. Brick-pattern panels are replaced as listed parts rather than rebuilt with mortar like a masonry firebox. We confirm which kind of fireplace you have before recommending any work.

• Type confirmed from the rating plate
• Panels replaced as listed parts
• No mortar patching on molded panels

The hearth extension in front of a prefab unit

Section R1004.2 says the hearth extension of a factory-built fireplace follows the listing of the fireplace, stays readily distinguishable from the surrounding floor and, when it is a listed product, complies with UL 1618.

In one maker's manual, that extension reaches 20 inches in front and 12 inches beyond each side, over a layer with a stated insulating value. We measure yours against your own model's figures when the hearth is part of the repair.

Why a prefab fireplace smokes

One maker's troubleshooting guide lists the usual reasons a fireplace smokes, including negative pressure in the house, blowers such as a range hood, wet wood, a dirty or blocked chimney and a chimney that is too short.

We work through that list in order, starting with the easy checks. Many smoking complaints end with a cleaner flue or a change in the house, and only some need parts.

• Negative pressure in the house
• A range hood or other blower running
• Wet or unseasoned wood
• A dirty or blocked chimney
• A chimney that is too short
