This contractor kept changing the dates for when he would show up. Once he set a date for Friday, but said he would confirm on Wednesday. Come Wednesday, and no phone call. Come Friday, and he just shows up. When he finally did the work, it was not as promised. No primer on fence, walls were not smooth textured properly, and paint was sloppy. He was supposed to come back to fix everything, then abandoned the job altogether. Nothing good here to say.
