Restoration is the middle ground: clean first, then seal every accessible joint with mastic rather than tape, repair the insulation, and where the liner is shedding but the duct is sound, apply an encapsulating coating. On the right system it delivers most of the benefit of replacement at a fraction of the cost.
This is the most common call we get, and the answer is almost always mechanical rather than a cleanliness issue. A duct run has come away from its boot above the ceiling, or something in the attic has crushed it. It’s often an inexpensive repair with an immediate, obvious difference — and it’s very common in Smyrna and other areas where a lot of the housing stock hit the fifteen-to-twenty-five year mark at once.
They fail differently. Attic ductwork dies of heat: the tape lets go, the insulation sleeve degrades, and stored boxes crush runs. Crawlspace ductwork dies of moisture: the insulation holds damp, liners break down, and you get the conditions for growth. Older homes in Decatur tend toward the second problem; newer builds toward the first.
Visible growth on or inside ductwork usually means moisture, and moisture has a source. Cleaning the surface without fixing the source guarantees it returns. If someone offers to spray a treatment on visible growth and calls it solved, get a second opinion — the honest sequence is find the moisture, fix it, then decide whether the duct can be saved.

We’ll show you the inside of your own ductwork before you commit to anything — and tell you if you don’t need the work.
Some ductwork can’t be cleaned back to healthy. When it’s torn, crushed, disconnected or full of mold, replacement is the honest answer.
The middle ground between cleaning and full replacement — seal the leaks, encapsulate the liner, restore the airflow.
The honest answer is every three to five years — but four things move that number, and one of them is specific to living in Georgia.
Why the $79 whole-house special isn’t a price — it’s a door-opener. And what actually determines what a real job costs.
