A Channahon Chimney Inspection and Repair, Step by Step
The job below is a composite, a representative Channahon chimney rather than a specific customer or a promised result. We built it from the kind of neglected masonry flue we see most often along the corridor, so you can follow exactly how an Apex visit runs, from the first phone call to the report we leave on the counter.
The call
A homeowner off Route 6 calls (815) 364-8959 in late October. The fireplace smells sour, a brown stain is spreading on the chimney breast, and nobody can remember the last sweep. Zack asks the usual questions: what they burn, how the draft behaves, whether they have seen water indoors. Those answers already sketch the problem before anyone climbs a ladder. We book a two-hour window.
Arrival and setup
Zack lays drop cloths from the hearth back into the room and sets up a vacuum with a sealed filter before touching anything. Soot control is the difference between a clean job and a mess you find for weeks. He checks the damper, the smoke shelf, and the firebox by hand, then heads to the roof to look at the crown and cap from above.
A level-two look with the camera
Because this chimney’s history is unknown and there is a water stain, a visual sweep alone is not enough. Zack runs a camera the full height of the flue. The footage tells the real story: stage-two creosote through the smoke chamber, two cracked clay tiles about halfway up, a crown webbed with cracks, and a cap half rusted away. We record all of it so the homeowner sees exactly what we see.
What the footage showed
The cracked tiles explain the smell and the stain, because flue gases and moisture have been seeping into the masonry. The failed cap let rain fall straight down the flue for who knows how long, and that is what cracked the crown and accelerated the tile damage. None of it is unusual for a chimney that has gone a decade without a look, and all of it is fixable without drama.
Laying out the options honestly
We don’t hand people a single take-it-or-leave-it number. For this chimney the path is clear: sweep now, repair the crown, fit a new stainless cap, and reline the damaged section rather than tear the stack apart. Zack walks through why relining the flue is the right call here, and when a full rebuild would be warranted instead. In this case it isn’t. Everything is quoted against the published pricing.
The repair
Over the scheduled work we sweep the flue to bare tile, grind and recoat the crown with a flexible sealant, set a stainless cap sized to the flue, and install an insulated stainless liner through the cracked section, sized to the appliance. The masonry repointing around the top courses goes in during the same visit so the top is sound in one pass.
Walkthrough, report, and outcome
We re-camera the finished flue so the homeowner can compare before and after, then leave a written report covering what we found, what we did, and when to come back. The fireplace drafts clean, the smell is gone, and the stain stops growing once the leak is sealed. That is the outcome we aim for: not a dramatic rescue, but a chimney put back to safe, boring, reliable service. If yours sounds like this one, start with a chimney inspection.
Frequently asked questions
Is this a real customer’s chimney?
No. It is a composite we assembled from the common neglected chimneys we see, used to show the process. It is not a specific customer, address, or guaranteed result.
What is a level-two inspection?
It adds a camera scan of the full flue to the visual check, so we can see cracked tiles, hidden creosote, and damage a flashlight from the hearth would miss. We use it whenever a chimney’s history is unknown or a problem is suspected.
Do you always run a camera up the flue?
Whenever there is a sign of trouble such as odor, staining, or an unknown history, yes. For a chimney on a known annual schedule, a standard inspection is often enough, and we will tell you which your situation calls for.
How long does a job like this take?
The inspection and sweep typically fit in about two hours. Repairs such as relining, cap replacement, and crown work are scheduled separately and sized to the specific chimney.
Will you show me what you found?
Yes. We record the camera footage and walk you through it, and on repair jobs we re-camera the finished flue so you can compare before and after.
How do I know if my chimney is this neglected?
If you cannot remember the last time it was swept, or you notice odor, staining, or poor draft, treat that as your sign and book an inspection before you burn again.
Are you certified?
No, we do not claim a certification. We work to NFPA 211 and follow CSIA guidelines, the standards that our inspection and repair work are measured against.
