Dun-Rite Ceramic Tile

Review: [redacted] of "Dun-Rite Ceramic Tile" was contracted to remove and install new coping and new tile on my swimming pool. Additionally, he was to remove two existing 2 1/2" slabs (approximately 48" X 8") and then reapply them at the end of the job.The work was initiated on June 9, 2013 but his workman broke one of the 2 1/2" chiseled slabs while attempting to remove it. [redacted] told me that he could no longer get 2 1/2" slabs and that he would have to replace the two pieces with 1 1/2" slabs. I was not happy with this, but he assured me that the job would be beautiful and that I would be pleased.He completed all the work on June 18th and everything looked good. It rained that night and the next day (June 19th) I was surprised to see that the two slabs had turned an ugly orange. I called him that very next day and he informed me it was probably iron in the stone and he would come out to fix it. On June 23rd he arrived and applied some chemical to the stones which appeared to remove the orange. I told him I was skeptical but if it worked I would be satisfied. I was out of town and returned on July 7th to find the stones as orange and as ugly as previously. I called him (left a message) on July 7th asking for a return call. One week later (having not heard from him) I called on July 14th, then on July 16th, then on July 17th requesting a return call. He finally called me on July 19th and told me he would be doing a job in my area and that he would come out next week (i.e, the week of July 21-28). Today is July 29th and he has yet to return for repair or to call me. I have no qualm with the coping nor the tile--they are satisfactory. The complaint is with the two slab stones on the spa which are of inferior quality and which are now bleeding rust down into the new grout of the tiles on both the pool and spa sides.Mr. [redacted]'s contract clearly establishes a "five year warranty." "Dun-Rite Ceramic Tile" clearly is "Dun-Wrong" on this job. I do not seek damages just correction.Desired Settlement: The entire job cost $6100--coping and tile OK. As stated above, I am NOT seeking cash or damages. I simply want the two rust-filled slabs on the spa removed/replaced and the rust that has trickled down into the new grout lines removed. Essentially, I want Mr. [redacted] to honor his "five-year warranty" on a problem that initiated the day after he was paid and left. This has been ongoing since June 9th--I have been more than patient and he is not handling this matter as a reputable businessman.
