sounds like a rebuild to me, do you have the skills?

if you feel you do, you would want to first remove all the damage, including wet insulation..rebuild the floors and insulate and seal with visqueen (sp)..caulk all areas where the frame and new construction touches.

when you put on new walls, use new real drywall not that flimsy wallboard..it will cost you less in the long run and provide better insulation.

make sure you have a modular home repair parts access available..as you will need to buy any parts from them that are non standard and will not fit your house..such as plumbimg and electric.

while you are down there..check your heating ducts..as they probably weren't put in well, they never are..you can restring them and do a better job and find that you save on heating and cooling costs.

sorry this happened to you

use braided metal water tubing next time

Is it just a standard caulking that would go between the floor and outer walls?

My insurance thankfully has covered the damage. I am electing to do the repair myself, for cost savings, so I can upgrade my kitchen, and add some extra cabinets. My kitchen is very tiny, with only 1 cabinet for storage, and approx 2' of work space. I will be tearing down a wall and replacing with a breakfast bar, since we also have no place to put a dining table.

Another question, what held the insulation up under the floor? My home is a 78, and there is no plastic sheeting under there. Would it be safe to add some? One thing that concerns me, is that if I put plastic under there,if moisture did find a way in, there'd be no way for it to escae, and I'd have moisture in the nsullaion. What I'm thinking, is that I'd put insullation between the floor joists, and hang it up there somehow. I am lacking the finances to completely reinsulate the entire trailer bottom, and I dont want to hang sheeting under the whole trailer when it's still so cold. Should insulation be hung by plastic, or something breathable?
