Is a Moisture Barrier needed??

| Posted in General Discussion on July 18, 2000 10:38am

*
We are currently in the process of purchasing a new home. When walking
around the house (that is near complete) my uncle(who builds) pointed out
an area where the inner/outer layers are visable, he noted that there was
no barrier at all(ie.tarpaper,tyvek).
We questioned the builder and he claims that this is to let the house
breathe. I live in the Pacific Northwest and there is plenty of rainfall.
And with walking around some new home projects around the City, everyone
has at least, tarpaper….
Looking for unbiased opinions on this matter.

Thank you in adv

    dorick.. if you mean that there is no tarpaper or tyvek behind the siding.. then i would find fault with the builder..

    but i'm unclear what you mean (((an area where the inner/outer layers are visable, he noted that there was no barrier at all(ie.tarpaper,tyvek). )))

    what kind of siding is it ?

    and where is the tarpaper missing from ?

    dorik:

    Use the breaktime search function and look for "housewrap" or "felt".

    What type of exterior finish does the house have... wood or vinyl siding, brick, etc? What are the exterior wall's sheathing made of?

    I think there definately needs to be something under the siding.

    I'm more concerned that you can see the areas where tar paper should be.

    stumped. i want to install a raised patio of brick pavers attached to the back of my house. my problem is my suspended bay doorwall (with a sliding patio door)protrudes about 18" above the ground. I am worried about packing fill sand and aggregrate beneath the bay construction. I worry this would be the same as building a bay door wall on the ground with no footing. where i live in michigan a 40" freeze/thaw footing is required. should i build a footing and retaining wall 40" deep below the bay housing to prevent the sand from being below the construction? if i do that, do i need to ventilate the new cavity formed below the bay? if so, what would be the best material for the new foundation wall i build, wolmanized with a pvc vent pipe? or what?

      *MikeThanks for the reply.Yes, I do mean there is no tarpaper behind the siding!The area that is exposed is where the height of the sliding glass door was raised for a taller slider. So, the siding from the outside needed to be cut open and would be finished with trim. The trim is not on, which makes the "layers" visable. That is the only reason that I know.I've also contacted the county to discuss CODE for this matter and was told that it IS CODE unless the sided is treated for that.More than likely I think the builder has messed up or has cut corn
