Hello , my house start has one stair crack on mortal brick out  side the house. Please refer for me the good contractor you know he has experiences. Thank you

Your looking for a contractor to repair the crack.  Usually the foundation repair company's will take care of that for you.

Anyone have a good experience with a foundation repair company that you can refer this individual to? 

This may not be a foundation problem.  Remember, the brick is not attached to the house. Look at the concrete where the foundation and brick meet if the foundation is cracking then there may be a big problem.  Just food for thought.  A friend of mine had his whole house redone and come to find out his daughter was throwing softballs against the house in that spot and had cracked the mortar.  Big expense for nothing.  Contractor never said a word.

Thank you . I apreciate.
