I was hired by a very honorable and wonderful builder to find a leak source neither their subcontractor, architect, contractor not to mention the homeowner could find on a very fine home he just built.
I ran some tests (like they all did but obviously not exactly as they did as I found it) on a balcony area where water was coming in the ceiling below.
After a few hours, I isolated an outlet on the wall of the balcony.
I wrote the rain leak finding report and put a photo of the flaw and an example photo of a good 100% workable method of repair.
He said he did it, it rained, water came in the same place and so he had me come out to "find another leak source" assuming the one I found had been standardly repaired.
I went out again and after looking at various areas with no result, I decided to check the repair he did on the electrical outlet.
What do you know; It still leaked! I documented it and again, re-iterated what I had stated in the first report as to a standard way to repair it.
He said, we are just going to remove the outlet all together and re install the cedar shingles.
Well, it rained again and it leaked again!
So he had me go out and "find another leak source". So this time I was of the opinion that he had fixed it as I saw no outlet so I tested the rest of the deck, walls, doors etc. within an inch of their life and NO leak!
So I started looking more closely at the area where he removed the outlet and I saw, in between the cedar shingles, some white paper that looked like the overlap was backwards so I tested it and BANG. It leaked!!!
My god I thought. How many times do I have to go out and get paid to find the same leak?
Well, this time he apparently got someone in there who knew what they were doing, got it standardly repaired and has not leaked since. (4 years ago).
I have MANY of these types of stories but I thought I would start with this short but bitter sweet one.
