Bat Guano Cleanup and Decontamination in Riverview
Where the deposit sits
On a house where the roost was in the roof void rather than the attic, the cleanup is not an attic job. The accumulation sits on the underlayment and in the tile channels, and what the homeowner sees is staining running down the outside wall below the roof edge. Cleaning the attic in that situation achieves nothing, because the material was never in there.
Where a colony did reach the attic, newer construction usually means a shorter occupancy and a smaller deposit than an older house would show, simply because the building has not been standing as long. That tends to make the work more contained, though it still has to be done properly rather than vacuumed and forgotten.
How the work is done
Contaminated insulation is bagged and removed, the affected surfaces are cleaned and treated, and the space is deodorized rather than masked. Where droppings have soaked into framing the timber gets treated at the surface instead of being covered over. Insulation goes back so the attic holds the R value it was built to.
Exterior staining is treated as part of the same job, since leaving it means the visible evidence of the problem outlasts the problem itself. Work happens in respiratory protection with the space isolated from the rooms below, because disturbed dry guano puts particulate into the air.
