Well, thank you for the invitation to reply ... this particular Brit is looking forward to November - 100 degrees and humid can lose its appeal very quickly.

Pittsburgh, where this duplex is at, has high humidity.

Florida can get up to 50% humidity up to 6 months a year, so there is a good chance moisture can build up.Depending on the type of ductwork you have, some materials are more indusive for mold growth.As for the floor, im not sure.

I'm trying to decide dark bamboo floors or dark hardwood floors (same price per sq/ft)...I'm in Houston, so humidity does play a factor.

I'm in SFL and the only slow months are September and October mostly because kids are back to school and it's hot and humid as hell here. 

The tell tale for nicotine with latex paint is the brown resin that seeps right through the latex paint ESPECIALLY in any area that will get humid (bathrooms and kitchens).

Given that most FL homes are slab homes, and has an extremely high humidity, eng'd is the best route to take.  

So the government ended up forcing people to come here...to a colony that was hot, humid,and filled with swamps and mosquitos.

I also like that it provides better moisture control which is good for my investment, it’s very humid here, walls will literally drip. 

Because this was a high-humidity environment, the padding was actually stuck in many places to the subfloor as well.
