"Claudio and his crew did an amazing job. They stripped my home down to the wood. He found areas of rot as well as pests and clean those up. He sealed every window pipe with waterproof tape. He repaired rot. He waterproofed and weatherproof the entire home, then re-shingles using high-quality materials to ensure my home would be waterproof endurable. He replaced my front porch, found more areas of rot and opened up the front and made my home look amazing. He discussed every step with me and planned with me the entire time. His information is solid and always leads you in the right direction. I am so fortunate to work with this man."

"I can’t sat enough about Sergio & his father & their work. They put in a railing on my stairs. It was a bit too high ,so he put it lower, for me. He even did me the favor of putting up a shade & drapes for me, since I can’t reach that high. My 1st review was lost somehow. He put ropes in my old windows. He worked ho*** ** that project & it was a hot day. He also put a doorbell on for me & nailed a loose fence. I will definitely use his service, again. I’m hoping he can put a new roof on my front porch. And a big plus, they cleaned up their mess. ???"
