I hired him to do a kitchen remodel.
Horrible work.
Cabinets are separating from the wall.
Cabinets are also uneven.
Cabinets make a horrible sound when opening them.
Kitchen sink won't run hot or warm water.
The kitchen floors have cracks.
We have tripped multiple times as a result of the cracks.
Thank god no one has had to go the hospital.
Extremely awful contractor and horrible work.
Stay far far away.
