Mr Kron came to my house to repair my front door latch and ended up replacing my whole front door . I witnessed a man install a new door with all hardware and weather stripping without once making a single mistake . Every step of the entire project flowed without difficulty from start to finish , it was amazing to watch. Mr Kron is very personable and attentive , he has skills that are earned from intense study and practice...I found a superior craftsman and know he stands behind his work. To anyone or any business in need of a guy to get things done --Mr Kron should be the first to call . .....he helped me ...and I will call him again ......thank you ...................P.
