There are a few tricky details that the contractor HAS to get correct to make sure moisture does not become a problem:1) If used for a roof, make sure the roof is built with a cold roof to allow for ventillation.

So the flooring will need to be completely replaced, but the real issue is moisture causing the wood to swell and "pop loose".The left hand wall where the baths are has a higher moisture content along the baseboard, and the wall between the 2 baths also had a high moisture content.

These houses are still settling and the engineered works better.LVT for the basement areas due to the moisture issues that can occur.Carpeting the steps from first floor to second does help with noise reduction.

Also, wind-driven rain is pushed through the gaps causing moisture to penetrate "the envelope".McVey offers a "lifetime" warranty, but I still have to pay for the labor to pull the oak interior trim, exterior trim, cut the calking out, pull the nails, drop the old window out and put the replacement in, and trim everything back up. 

I am trying to specialize in energy efficient homes and I'm thinking that the thermal and moisture protection division will vary a lot due to differences in the climate the house is being built, precipitation, solar orientation of house, level of energy consciousness of buyer, price of solar pv, local source of recycled materials, additional labor to air seal and insulate correctly, etc. 

As for the basement I knew from my inspection that the sump pump wasn't working in the basement and a bit of moisture was coming in from the back wall.

Tile will hold up the best to moisture but have to be careful if there's deflection in the subfloor then the tiles could crack.

When it is set, yet still has moisture in it, it can be scraped to smooth so that top coats go on nicely.

The tenant had just notified me that this crack has appeared in the bathroom ceiling,  No moisture appears to be in the ceiling.  

If you just have a window, maybe you just need to educate your tenant about moisture issues.
