Last weekend, my husband and I went to the Monterey Peninsula for a couple of days to celebrate our 25th wedding anniversary.  We had a wonderful time there, but would not return to the hotel where we stayed this time.  The worst issue was the mold in the bedroom along the wall and baseboard.  I brought it to the hotel’s attention and it was “cleaned”, but I think the issue is far from solved.

Since we sometimes run into issues with mold in our real estate transactions, I wanted to take the opportunity of having these before & after photos to discuss what to do about it when buying or selling homes.  Luckily, here in Silicon Valley it is not so humid as it is along the coast, so we are helped on that count.  But it is still very possible that you will run into mold or mildew when trying to buy or sell property.

First, I should state that mold is naturally occurring and it is not possible to completely eliminate mold spores from your home.  The question is whether or not the mold inside the house is the same kind and density as the mold outdoors, or whether something unusual is harbored indoors.

Mildew and mold need moisture and the right, mild temperatures to thrive – eliminate the source of water and the mold will go dormant.  Please note that it will not die when the moisture is eliminated – it just goes into a sleepy state.  If water is later reintroduced, the mold spores will spring back to life.

In my experience, the most common place to find mold in the San Jose area tends to be in bathrooms, particularly around older aluminium windows (which tend to be very cold and collect condensation). Mold on these window frames is easily cleaned by using a solution of water and bleach, and it can be prevented by better ventillation and heat, which allows the window frames to dry out. Likewise it’s very easy for mold to grow in showers and tub areas due to the high amount of water present.  That water needs to be able to evaporate, otherwise you’re inviting mold to take hold.

Find mold on sheetrock, wood or carpeting?  First you must discover the source of the moisture.  Most likely, there’s a leak somewhere, either a plumbing leak or around a door, window, roof or flashing.
