Today I reached out to john to have him inspect some of his work that cost me $8,000 in damage, He was rude and arrogant to me talking over me and belittling me. His professionalism was lacking in its place was a defensive person that chose to attack me on the phone talking to me in a extremely disrespectful manner. All I wanted to to ask him was to inspect his work that 2 restoration companies said was wrong, 1 roofing company and a engineer all said was wrong.
This poor workmanship resulted in thousands of dollars to me.
I WOULD STRONGLY ADVISE NOT USING THIS COMPANY.
