    The previous reviews made sense when he stopped responding putting time sensitive job in danger. Stay away, unreliable person. Had to arrange a new plumber last minute at greater costs. Always read reviews.

    Repair or maintain roof or gutter-
    I hired Shawn to fix major issues with my walkout balcony—a sagging dormer roof, rotted posts and underneath structure and flat roof pooling. He quoted a 2-day job with 50% upfront. Work dragged on for over a month with poor communication and slow progress. Key contract items weren’t completed or done improperly. He didn’t jack up the roof enough to fix the eaves slope, did not reslope flat roof, didn’t remove the old membrane and instead installed the new one over the old one. The membrane ends abruptly near the threshold, with visible old material and substrate along the edge, and several other things can't fit in this review. When I raised concerns, he said “wait until I’m done.” On May 13, he claimed the job was done and demanded the rest of the payment. When I refused due to unfinished work, he threatened to lien my property and destroy the work done. He also said “You’re asking for a Rolls Royce for your budget.” when he's the one who wrote the contract. I simply agreed and paid.

    Interior painting-
    We were extremely pleased with the work done by AMV contractors. They fixed an exterior wall that was crumbling away, they got an electrician in the pot in pot lights and add a fan upstairs. Then they painted our hallways, taking care to use a primer to seal the 25 year old oil/latex issues we were having and give us a nice bright hallway again. We will definitely be using them again in the future and highly recommend their work.
