In Dallas, the damage is driven by sun and storms, not frost. A chimney crown takes direct Texas UV for years until the concrete crazes into a web of fine cracks; then a DFW thunderstorm drives rain straight through them. By the time a stain shows on the ceiling, water has usually been tracking in for a season or two. A documented inspection catches it while it's still a small line item.
Our techs check the firebox, damper, and smoke chamber from inside, then the crown, cap, flashing, and exterior masonry from the roof — where most Dallas water problems start. You get a written verdict on every component with photos, and a separate line-item quote if anything needs work. If a nest or heavy debris turns up, a Dallas chimney cleaning clears it — and because the $49 credits toward same-visit work, the inspection pays for itself the moment anything real is found.
