I have several concerns about my 20 year old house
There is a vertical crack on the 2nd (top) floor of the house Extending from the top of the ceiling down about 3 feet. It seems to have developed recently and this has been a wet and rainy season (washington state). The crack look like a long thin V shape, no shearing. The widest space (top of the V) is about 1 to 2 mm. I need to know what is causing this and how to either reverse or stop it from getting worse.
Who should I hire to check/fix this problem? A civil enginner? A house inspector? A general contractor? I prefer a "one-stop" shopping solution, unless doing so would significantly compromise the quality of the solution. I have the internet and yellow pages, but don't know where to look.
