Fireplace Repair and Chimney Sweep in Denville, NJ

We replaced a damaged firebox panel and swept the chimney at a Denville home. Here is what that kind of repair involves.

Dr. Sweeper has completed a project in Denville, Morris County: a replacement firebox panel together with chimney sweeping. The panel replacement restored the damaged firebox surface, and the sweep serviced the fireplace system. The project is shown below.

Denville is mostly detached, owner-occupied housing. The Census finds about 77% detached houses and 88% owner-occupied, with a median build year of 1964 and about 29% of homes built before 1950.

The firebox is the part of a fireplace that takes the heat directly. When its panels or joints fail, the fireplace is not safe to keep using as it is.

Firebox panels and cracks

Fireplaces take repeated heating and cooling, and the lining cracks over time. Small hairline cracks are common, but whether one is acceptable depends on the firebrick or panel, where it is and the manufacturer's requirements, so have it assessed. Wider cracks, missing pieces or gaps through to the framing behind are different. They allow heat to reach parts of the house not made to take it.

Replacing a cracked or broken panel restores the lining. The right repair depends on the type of fireplace: a factory-built unit uses manufacturer-specified panels, while a masonry firebox is repaired with firebrick and refractory mortar. Our guide to cracks in the firebox explains how to judge them, and the Denville project shows the job.

A crack you can slide a coin into deserves attention before the next fire.

Checklist

Checking your own firebox

  • Look for cracks wider than a hairline.
  • Check for missing or loose pieces.
  • Look for gaps between panels.
  • Check for scorching on the surrounding wall.
  • If in doubt, do not use it until it is checked.
