What the numbers suggest for chimneys in Raritan Township

Census estimates place 54% of Raritan Township's 9,331 housing units in the 1980 to 1999 group and 19% in 2000 or later. Only about 11% are older than 1960. Fireplaces in homes of the 1980s and 1990s are often factory-built units with metal flues, many inside framed chases; the factory-built fireplace guide explains what owners can and cannot do with them.

About 80% of occupied homes heat with utility gas, but fuel oil still heats about 11%, with electricity at 5% and propane at 2%. An oil boiler or furnace venting into a masonry flue is a different inspection subject from a fireplace, and the oil flue guide covers the soot and scale such a flue collects.

About 67% of units are detached houses and 22% are attached homes such as townhouses. The figures describe the township and Census estimates carry a margin of error; they cannot tell you anything about the chimney in a particular listing.

What a chimney inspection at sale is meant to answer

CSIA, the Chimney Safety Institute of America, describes three inspection levels and lists "the sale or transfer of a property" among the occasions that require a Level 2 inspection. A Level 2 covers everything in a basic Level 1 plus the accessible parts of the chimney in attics, crawl spaces and basements, a check of clearances to combustibles, and a visual inspection of the flue's interior surfaces by video scanning or other means.

A chimney inspection for buying or selling follows that scope. Findings come with photos, and you leave the visit with the report in hand, which helps when an attorney review or inspection contingency is running on a short clock. Our guide on how to read a chimney inspection report helps you sort what you receive.

Three things to pin down in a house from these decades

1. Which kind of fireplace it is. A factory-built fireplace is a listed system: the firebox, flue pipe and top work together, and replacement parts have to match the original maker's system. A masonry fireplace is judged on its brick, mortar and tile instead.
2. What else vents into the chimney. Find out whether a furnace, boiler or water heater uses a flue, and whether any of them has been replaced. A newer high-efficiency furnace that vents through the wall can leave the water heater alone in an oversized flue.
3. The condition of the top. On a framed chase, the metal top that sheds rain wears with age. Rust streaks down the siding are a clue worth photographing; see rust and brown stains on a chimney.

Alarm certificates when a Raritan Township home changes hands

New Jersey requires carbon monoxide alarms in one- and two-family dwellings that contain a fuel-burning device or have an attached garage, placed in the immediate vicinity of sleeping areas (N.J.A.C. 5:70-4.19). The Raritan Township Fire Marshal's residential inspection guidelines say no certificate will be issued unless the property complies, and call for CO alarms within 10 feet outside every bedroom. The Fire Marshal's office handles the certificate; the chimney inspection is a separate matter.
