Answer the call after the chimney fire, and send every flue its yearly reminder yourself.

Most homeowners ignore the chimney until something makes them look. The planned call comes when the first cold night reminds them the fireplace hasn't been swept. The urgent call comes after smoke backs into the living room, a smell won't go away, or a chimney fire brings out the fire department. The Chimney Safety Institute of America's after-fire guidance points out that a fire crew's training covers containing and putting out the fire and does not include cleaning, inspecting or evaluating the chimney, and it advises against using the chimney until a qualified professional has swept and evaluated it. The third call is a home sale. InterNACHI's home inspection standards of practice leave the inside of chimneys and flues out of the inspector's required scope, so a buyer who wants to know what is inside the flue calls a sweep, often while a contract deadline is running. Home inspectors, agents, HVAC contractors replacing a furnace, roofers working around flashing and insurance adjusters can all send work your way, and they can only pass along a sweep whose number they have and who answers.

Marketplace leads fit this trade poorly. A fall sweep request from a platform is a single job from a customer the platform introduced, who may be hearing from other companies at the same time. On Thumbtack, a homeowner can contact no more than five pros in a search's first four hours, and more once that window closes, per the platform's quality commitment. Angi's filing for 2025 books match fees from pros as revenue regardless of whether the pro ever provides the service. The value of a chimney company sits in the addresses that come back every year. CSIA's homeowner FAQ quotes NFPA 211, the National Fire Protection Association's Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances, which says chimneys, fireplaces and vents "shall be inspected at least once a year." NFPA's heating safety tips give homeowners the same yearly advice. A yearly service backed by a national standard is a repeat customer list in the making. Build it in your own CRM, where a platform can't charge you to reach it again.

The year bends around the heating season. NFPA names December, January and February as the peak months for home heating fires, and the booking rush comes just ahead of them, from the first cool weeks of fall into the holidays. Where wood or pellet stoves heat the house all winter, heavy burners may need a second sweep before spring. In warm regions with short burning seasons the fireplace can sit cold for months, so home-sale inspections, gas appliances, caps, leaks and dryer vents make up more of the calendar. Spring and summer are for masonry, crowns, liners and waterproofing, plus odor and wildlife calls, including chimney swifts, which appear on the federal list of birds protected by the Migratory Bird Treaty Act and nest in uncapped flues. Rules on who may sweep, rebuild masonry, install liners or touch a gas line vary by state and sometimes by city, and so does sales tax on chimney work. Our state guides name the licensing and tax agencies for each state, and those agencies have the final word. None of this is legal or tax advice.
