Why are NEPA chimneys so prone to damage?

NOAA's 1991 to 2020 normals for the Wilkes-Barre/Scranton International Airport show about 39 inches of precipitation and about 45 inches of snow a year, with January averaging about 28°F. That means many freeze-thaw cycles each winter, and water in masonry is what breaks chimneys down. Add the region's housing, much of it built in the coal era of the late 1800s and early 1900s, and you get a lot of chimneys with soft old mortar, aging clay liners or no liner at all.

What did coal do to the region's chimneys?

Scranton was known as the Anthracite Capital of the World, and Wilkes-Barre as the Diamond City. In 1808, Judge Jesse Fell of Wilkes-Barre demonstrated an iron grate that made anthracite practical to burn at home, which helped make coal a household fuel. Coal's decline after World War II, and the 1959 Knox Mine disaster, ended the mining era, and most homes switched to oil and gas. But many chimneys built for coal remain, and coal combustion is acidic and hard on masonry and liners. Some homes still heat with coal stoves and furnaces today.

How often should my chimney be inspected?

NFPA 211, the national standard for chimneys, fireplaces and vents, calls for an inspection every year and cleaning as needed. Chimney professionals commonly describe three levels of inspection: Level 1 for routine checks of accessible parts, Level 2 when buying or selling a home or changing appliances or fuel (usually including a camera scan), and Level 3 when a serious hidden problem requires opening up the structure.

What should I know about liners?

A liner protects the masonry and house from heat and corrosive gases and must be sized to the appliance it serves. When an old furnace is replaced with a more efficient model, or a water heater is left alone in a big flue, the chimney may be oversized, which causes poor draft and condensation. Stainless steel liners rated for the fuel are the most common fix. Coal burners need liners made for coal.

What does Pennsylvania law require of contractors?

Under Pennsylvania's Home Improvement Consumer Protection Act, contractors who perform more than $5,000 a year in home improvements must register with the Office of Attorney General and display their registration number on contracts, estimates, proposals and advertisements. The contractor must give you a complete copy of the contract, and a contract missing required information isn't enforceable against you. You may cancel within three business days of signing, except in certain emergencies. A contractor can't take payment before the contract is signed, and on contracts over $5,000 can't ask for more than one-third of the price before the project is completed. Look up registrations at the Attorney General's contractor search, or call 1-800-441-2555.

How do I stay safe with a fireplace or stove?

Keep working smoke and carbon monoxide alarms on every level.
Burn only dry, seasoned wood, or the fuel your appliance is rated for.
Have the chimney inspected yearly and swept as needed.
Put a cap on every flue.
If you suspect a chimney fire, get out and call 911, and don't use the chimney again until it's inspected.
