Ok, the crawlspace under our house got flooded. One company said we
needed to have the insulation replaced on the duct work under the
house as well as have the plastic removed that covers the ground and
get fungicide put down. They want to charge about $8400 to do this
(about half just to do the ground/plastic). Another company said we
needed to actually replace the ducts which would be about $7000 but he
doesn't insulate them which doesn't make sense to me. We haven't
smelled any musty odor or anything coming from the air vents. Anyway,
my questions a

1. I assume that HVAC contractors are the people I need to get
estimates on for this work correct?
2. What exactly goes wrong with metal duct work when it gets wet that
you would have to replace them? Do they rust or something?
3. Do these prices sound reasonable (I intend to get more quotes)?
4. What additional work if any would you need to have done with
getting your crawlspace flooded?

Any additional thoughts/opinions are appreciated also.

Thanks

If they have been under muddy water for a while they may have fungal
spores growing in them. I’m not sure how you could clean that out. If
the insides are clean of fungus and if the ducts are metal are they
insulated on the inside or outside? If they are only insulated on the
outside is it fiberglass insulation? If they are not insulated on the
inside then there is no reason to replace them unless they are rusted;
you could just replace the outside insulation if they’re not. Are your
ducts square or round? If they are insulated on the inside you might
as well replace them because they will have to be taken completely
apart anyway. There is no reason why you have to have metal ducts
installed. You could just have flexible ducts instead.

Contact a professional disaster clean up place. They will probably be
able to bill your insurance company. Keep track of your work on it also.
You can bill those hours against the cost of it for deductible.

A cleaning company makes sense, he only called companies that replace
things. Ducts have to be opened to see if there is damage
