Bishop Contracting

Had stairs made from buying a new home from Clayton. Asked for stairs to be built a bit larger than what original size was, charged 170.00 for difference. Stairs started cracking took over 61546 weeks to even get a response, then came out repaired one stair never even looked at any other stairs one week later another stair cracked in the same place. He now says that he doesn’t offer ANY warranty and he cannot be responsible for the lumber he chose to install? Do not use this contractor is my word of advice.
