drywall problem

does anyone know of a good website that shows pictures of common drywall problems???

my inlaws have an entire wall (it is an exterior wall) that has one window...below the window and on up about 4 feet above are the problems...the paint is chipping off in 1 inch pieces...the surface is really bumpy (not smooth)...i can't really tell what is going on...

if i take pictures of the problem, what do i need to do so people can see them on the forum???

Post the photos to a file sharing website. Photobucket or Picasa, etc. It sounds to me like water intrusion from the siding, or window installation... likely from a window, roofline or penetration that is ABOVE the window where the damage is showing up.

Simple fix but you need to correct the cause.

This looks like a moisture problem from inside. The reason I think this is because there does not seem to be the staining that would be typical of the damage from a leak.

How old is the house? Is there insulation in the walls? Is it possible that the insulation was damage or removed in the affected area's?

What room is this?
Might also be a poor priming job.

Might be that dust was on the drywall panels and not removed prior to painting.

The painters among us may have some other ideas.

I've had to repair that very type damage caused buy a few unrelated problems: window a/c leaking back, instead of to the outside.

Another cause at another place was leaky window sills.

Another house had a leak from exterior eaves where water entered the interior by the top framing plate area and soaked the insulation and caused mildew-mold in the wall. Had to pull it all out, wear mask, clean it all up including the fungal growth and powder, spray on bleach, set up fan to dry for days, after dry put in new insulation and vapor barrier and resheetrock. And had the roof drip edging and first shingle courses done right, to prevent this from happening again, including from icedaming.

In the case of an OLD a/c installation problem, simply required scraping off the alligatored paint and mud-skimmed the area, and let it go at that.

The lack of water stains makes me think the paint was applied over some type of contamiment. Scrape off everything that's loose and rub your finger a cross the wall/ceiling, if it comes back clean, you are good to go. If you get any dust on your finger, prime with either an oil base primer or zinnser's gardz. It should then be ready to patch, prime and paint.
