"Alex and his crew did a beautiful job on our existing deck floor. They were professional and courteous. I would have given them a Five Star Rating, but my contract also included installing one window shutter which had to be special ordered. Our deck floor was completed and the final payment was paid before the window shutter arrived. I called Southside Construction several times for someone to come back to hang my window shutter and complete the contract, but to no avail. "
