What the numbers suggest for chimneys in Pemberton

Pemberton Township's heating mix is broader than many nearby suburbs: Census estimates show utility gas in about 53% of occupied homes, electricity in 25%, fuel oil in 16% and wood in 1.4%. Oil boilers and furnaces push their exhaust through a chimney flue and leave soot and scale behind, which our guide to flues serving oil heat covers in detail. Wood-burning households deal with creosote, the fuel for most chimney fires.

Half of the 10,647 housing units were built from 1960 to 1979, and another 17% from 1940 to 1959. Chimneys of those decades were commonly built with clay tile flues, and the oldest have now served for more than 60 years.

Detached homes account for about 74% of units. Like all Census figures here, these describe the township as a whole, never a specific house.

How a chimney fire starts

CSIA explains that as smoke rises into the cooler flue, it condenses, and the residue that clings to the flue walls is creosote, a highly combustible material. Restricted air, unseasoned wood and a flue running cooler than normal all speed up the buildup. Once enough has collected and the flue gets hot enough, the deposit can ignite.

CSIA describes two kinds of chimney fire. A free-burning fire is loud and hard to miss. A slow-burning fire may go unnoticed, yet it can reach very high temperatures and damage the flue and the structure around it. That second kind is the reason a chimney can look fine from the living room and still need repair.

If you think the chimney is on fire right now

The free-burning signs CSIA lists include loud cracking and popping, heavy dense smoke, an intense hot smell and a low rumble that people compare to a freight train or an airplane flying low. Flames or smoke may shoot from the top of the chimney.

After a chimney fire, before the next one

CSIA advises against using the chimney again until a qualified chimney professional has cleaned and evaluated it, and its inspection guidance lists a chimney fire as a trigger for a Level 2 inspection. CSIA's technical paper on chimney fire damage treats a change in the creosote's condition and damage to the flue lining and chimney walls as evidence that a fire occurred.

Because a slow-burning fire can pass unnoticed, its evidence often turns up later, during a sweep or inspection. Our guide to the signs of a chimney fire lists the clues a sweep looks for, some of which you can spot from the ground or the hearth.

Our chimney fire damage inspection records the flue on camera where access permits and gives you photos of the findings. Note the date of the fire and anything the fire department told you, since that helps the evaluation. If the clay tiles or liner were damaged, the options range from resurfacing to a new liner, and the report explains which the findings support.

Keeping the next one from happening

CSIA sums up prevention in a short phrase: clean chimneys don't catch fire. Its list includes burning seasoned wood, opening the damper fully so the fire gets enough air, and a yearly inspection, followed by sweeping and repairs when the inspection calls for them. EPA Burn Wise cautions that smoldering fires are unsafe and inefficient, and recommends hot fires built with dry wood. Our guide on creosote sweeping logs explains why those products do not take the place of a sweep.
