A good annual inspection isn’t a vague look around, it’s a sequence. This is ours, refined across thousands of DFW rooftops, top of the chimney to the firebox floor.
What we check up top
Cap: present, secured, screen intact, no rust-through. After spring hail season, dents and displaced caps are common across North Texas
Crown: hairline cracks, pooling marks, missing edge. The single most common failure we photograph in Dallas
Masonry: spalling faces, open mortar joints, efflorescence (that white chalky staining)
Flashing: lifted or dried-out seals where the chimney meets the roof, the #1 source of ceiling stains
What we check inside
Flue: creosote depth and stage, obstructions, visible tile condition
Damper: opens fully, seals when closed, no rust binding
Firebox: cracked or loose firebrick, failed mortar joints, rust at the grate
Smoke chamber: buildup and surface condition, a rough or dirty chamber is a draft killer
Draft test: the system actually pulls, before you find out the hard way in December
Every line item gets a photo. The full findings become your baseline for next year, which is exactly how a maintenance plan catches slow-moving problems: same checklist, year over year, with a photographic record.
The five checks you can do yourself
Between professional visits, these take ten minutes each season and catch most surprises early:
- Walk the perimeter after a freeze. Brick chips or flakes on the ground mean spalling has started.
- Look at the ceiling near the fireplace after heavy rain. Any new shadow or stain is a flashing or crown conversation.
- Open the damper and listen. Scratching, flapping, or chittering means you’ve got a tenant.
- Smell the firebox on a humid day. A sharp campfire smell signals creosote that’s due for a sweep.
- Eyeball the chimney from the street. Any visible lean or a gap opening between chimney and wall is a call-us-now item, our clay soil moves foundations and chimneys with them.
Dallas-specific note: if your home was built in the 1970s-80s building boom, put extra attention on the crown. We routinely find original crowns poured thin, with no overhang, on homes of that era, they shed water straight down the brick and fail decades before a properly built crown would.
When to schedule the professional visit
Early fall, before the first cold front. You beat the seasonal rush, and if the inspection turns up a repair, there’s still warm, dry weather for mortar to cure properly. Book it once a year, every year, the CSIA standard, whether you burned two fires or two hundred.
