Jr Mandel review about company A & T Gutter Services

I just had A & T Gutter Services install seamless gutters around the 3 sides of my home. I have to say that I would not use them again. The work, once it was completed, was not bad and was what I expected. However, getting it done was the challenge. They were supposed to start on a Tuesday, then delayed a day, then another day. Thursday 3:30pm he shows up to start. 13 days after initial scheduled start date, Lots of calls to find out where they are and why it is not done; late in the evening (at dusk) they finally finish. He had me walk around to make sure it was done to my satisfaction. He had missed 3 water diverters which he promptly installed. It is now dark and tell him I want to check it out in the day light, run water through it to check for leaks. He insisted on Prompt payment in the dark of night. I reassured him after I had checked it out in the daylight, the following day, He would be paid in full or I would call to have him out to fix whatever I found. He was not happy and was VERY Unprofessional and discourteous in demanding payment. In the morning, I found leaks in the seams (above bay window). To their credit they were out within an hour or so of my call, he fixed the leak and final payment made. Based on duration, professionalism and timely installation...I Can Not recommend them.
