    I'm not sure what stains Charlie is referring to, but hardboard siding would not have tannin staining,

    Jerry,

    I wonder if he is thinking of the oily stains on siding that is caused from rodents entering an opening?

    Just thinking here.

    Charlie, I am sure you've already gooooooogglled it, but if not do, and usually as I have found is a problem with lack of or poor priming practices a well as an occassional termite of carpenter ant bladder problem

    Blame that on the rodents parents ... they never made their younguns wipe their feet, always left that dang oily trail behind.

    Tom,

    Welcome to the Board.

    Denver Recorded 3.06 inches of rain in April.

    I could not find data on May. ( rained lately? )

    Perhaps the stain on the home is a latex product that has allowed moisture to soak through in the lighter applied areas of staining.

    Really looks like a paint problem. 1992, I doubt that is the original paint. Could be problems from the original paint that was painted over.

    It also looks like mildew. Notice how it is not on the trim around the window? Could be a different paint or newer wood.

    Look's like mildew stains from lack of sunlight and ventilation. paint with a Mildewside may work but a bi annual power washing would aslo work wonders.

    good points boys.....
    as the condition is consistent on all sides of the home (and others in the neighborhood), i lean away from mildew issues.
    i am beginning to consider paint as the issue and not the siding.
    the siding itself is in good condition with no delamination or other visible signs of deterioration.
    i'm wondering if a new paint application beginning with a primer or other sealing product (Kilz?) might solve the issue although only time would really tell.
    hmmmmm......

    A good cleaning with TSP might work. Then a good scraping and repaint with a GOOD quality paint.

    Seen this same thing once on a home and the guy told me that his landscape company had sprayed dormat oil all over the outside for some kind of pest.

    Just a thought. Maybe everyone is using the same guy.

    If it's hardboard I would not go scraping that stuff.

    If it is like that on many houses throughout that subdivision you could contact a good local paint distributor to come out, look at it to make sure it was a suitable substrate for their paint, then ask them to give you a product schedule and a specification for preparation.

    With it prevalent throughout the subdivision, and being as most homes were likely constructed at the same time, it is quite possible that it is something with the siding, the manufacturing of that siding, the storage of it, the preparation prior to installation, the installation of it, and even the original painting of it.

    My guess is that it would be prudent to remove some and look at the back side of the siding and the wall structure, sheathing/no sheathing, insulation condition, etc.

    I wonder if it is some of that alkyd latex, where they try to mix oil and water based paints. Then if it sat in the pail too long, maybe you'd get that kind of blotchy mess. Might be hard to remedy, too.

    Was it definitely paint? Could it have been a solid hide stain? Paint is capable sealing in many applications; however, stains allow for bleeding. If the it is hardboard that was stained it will most likely turn ugly.
