Attic Mold Remediation in Gonzales, LA
In most Ascension houses the attic is where the air handler lives, where the flex duct runs, and where nobody goes except to get the Christmas boxes. It is also the most humid space in the house nine months a year, and the warmest, with a cold air conditioner sitting in the middle of it. Dark staining on the underside of the roof deck, a wet patch of insulation under the unit, a bathroom fan that has been dumping steam into the rafters since the house was built — those are attic calls. Call and tell us what you saw up there.
Where it starts
Three sources cover most of what we see. A roof leak, often at a vent boot, a valley, or the flashing around a chimney or a satellite mount, that runs down a rafter and stains the deck below it. An air handler that sweats or a drain line that backs up, soaking the platform and the insulation around it. And a bathroom exhaust fan that vents into the attic instead of through the roof, which puts a warm, wet plume on the same patch of sheathing every morning. New construction doesn’t stop any of the three.
Why a new roof still leaks into the attic
- New construction doesn’t stop leaks — a vent boot or a flashing seam fails on a five-year-old roof as readily as an old one.
- One roof leak changes everything below it: the deck, the insulation, and eventually the ceiling drywall.
- Moisture that gets trapped in a sealed attic assembly has no dry season to escape in.
- After a leak in a recently built home, the things to look for are a ceiling stain, sagging insulation, and a smell near the attic access.

How the attic gets cleaned
We seal the attic access and put the space under negative pressure so the work doesn’t push spores down through the ceiling. Roof decking and rafters stay and get cleaned in place, then HEPA-vacuumed. Insulation that got wet and moldy comes out in bags — it can’t be cleaned. If the ceiling drywall under the leak is stained through, that section comes out from below with the room sealed. We tell you what we found at the source, whether it was the roof, the unit, or the fan, and what has to change for the cleaning to hold.
Ascension notes
The subdivisions that went up around Dutchtown, Prairieville, and the Hwy 44 corridor in the last twenty years almost all put the air handler in the attic. That’s a lot of cold equipment in hot, wet air, and the platform under it is the first place to look. If a musty smell comes with the AC rather than sitting in the attic, the growth may be in the system itself; see HVAC and duct mold remediation.
