The owner gives a good sale talk. But, when it came time to complete the work they took their time and did not meet the proposed time frame. Also, I continuously experienced poor communication, was supposed to have had four windows installed and only received two of them. There were several excuses given for the other two and I lost money.
This company is not accredited with the Better Business Bureau, after I was told they were by the owner. Do not waste your time !
