    Multi-Room Remodel project

    Peter Alexander's work is sloppy according to industry professionals and not up to the SF building code, as told to me by DBI inspectors. He did not follow the engineer's plans, leading to structural problems with our building. He abandoned this project after taking all of the money upfront, even though that is illegal. I have to hire a new contractor to correct and complete his work.
    Response from Bioneer Builders July 19, 2019
    I entered into contract with this Kristy G and as a result of Her and her husband constantly changing their minds on the contract and the work that we had been performing which resulted in our not getting paid for numerous outstanding invoices on the work on their property which resulted in my needing to cease working until it was resolved which resulted in the theft and conversion of all my equipment and tools by Kristy G and her husband Ali after they had refused to allow me through my attorney to retrieve my equipment and tools. These people are deceitful and liars.

    rebuilding of second story veranda

    Peter and his crew did an outstanding job on a difficult "rebuild" of our outdoor, attached second floor veranda. We needed wood-rot completely removed and the deck rebuilt, painted and waterproofed. The wood replaced, along with the great craftsmanship, made us very happy. This was all done with Peter successfully maintaining the support of three heavy antique columns Then there was the painstaking job of replacing and waterproofing the flooring of it, all along having to maintain the integrity of the original, heavy cement balustrade. The work was completed in a timely manner and the price more than fair.

    Garage Construction project

    Peter really tries to keep on top of things and comes by daily--taking down the garage went well--now we still need the permits from the city (they are overloaded and under staffed, I feel very confident that Bioneer will do a very good job--
