Cracked panels and worn fireplace parts fixed in Windermere

Glass doors on a factory-built fireplace

Glass doors on a factory-built fireplace have to suit that fireplace. Section R1004.5 of the residential code says a gasketed fireplace door shall not be installed on a factory-built fireplace unless the fireplace system has been specifically tested, listed and labeled for that use under UL 127.

One maker offers its own door models for each size of fireplace. Before recommending any door repair or replacement, we identify what the listing allows, since a door that fits the opening may still be a door the fireplace was never tested with.

The ember strip at the front edge

An ember protector ships with some factory-built fireplaces, as a galvanized sheet metal strip fitted between the hearth extension and the bottom front edge of the fireplace. One maker's manual says it protects against glowing embers falling through that joint.

When a hearth has been redone, that strip is sometimes lost. We check for it and fit the maker's part or the specified strip before the joint is closed again.

• Strip present under the front edge
• Maker's part or the specified sheet metal
• Joint closed once it is in place

Repair or replace a prefab fireplace

A prefab fireplace is worth repairing when the damaged parts are listed, available and field replaceable, and the rest of the unit is sound. Replacement comes into the conversation when non-replaceable parts are damaged, parts are gone or the firebox itself has failed.

We put the reasons in writing either way. Fireplace replacement is handled as its own installation job with its own scope, so the choice stays clear.

• Parts listed and still available
• Damage limited to field-replaceable parts
• Firebox steel sound
• Chimney system intact or repairable

A cracked firebox floor panel

The floor panels of a factory-built firebox carry the grate, the fire and the ash, and they take the knocks from logs and tools. Cracks there often show before the side panels wear.

One maker divides the floor into bottom rear and bottom front panels, so a cracked front piece can sometimes be replaced alone. We check both before ordering.

• Bottom front panel
• Bottom rear panel
• Grate position over the floor
• Retainers along the edges
