How to use this infographic
Think of the four sections as a quick self-check. If you spot any of the six warning signs, it is time to book a chimney inspection. The yearly schedule shows when to act even when nothing looks wrong — because caps, crowns, and liners wear out whether or not you light a fire. The creosote stages explain why a professional sweep matters: once buildup reaches the glazed third stage, it is both difficult to remove and dangerously flammable. And the last section is the bottom line — what regular care actually protects.

Frequently asked questions
How often should a chimney be inspected?
Every year. The widely accepted standard, which we follow under NFPA 211, is an annual inspection for every chimney — wood-burning or gas, heavily used or barely touched — plus a sweep whenever buildup warrants it.
What is the most common warning sign homeowners miss?
Water-related signs. White staining (efflorescence) and flaking brick (spalling) look cosmetic but signal moisture moving through the masonry, which only gets worse if ignored.
Why do the three creosote stages matter?
Each stage is harder and more flammable than the last. Regular sweeping keeps buildup at stage one, where it brushes away easily, instead of letting it harden into the glazed third stage that fuels chimney fires.
Is an annual inspection necessary if I rarely use my fireplace?
Yes. Even an unused chimney is exposed to weather, animals, and aging. The cap, crown, flashing, and liner all deteriorate over time regardless of how often you burn.
When is the best time of year to schedule service?
Early fall, before the first fire and before the seasonal rush fills the calendar. Spring is a good second window to catch any moisture damage from winter.
Can I share or print this infographic?
Absolutely. It is meant to be a quick reference — share it with family or keep it handy so the warning signs and schedule are easy to remember.
What should I do if I notice several signs at once?
Do not light another fire until the chimney is checked. Multiple signs often point to a combination of buildup, moisture, and masonry issues. Call us and we will inspect it and explain exactly what is going on.
