Client Reviews

    BRIAN LUGO

    A string of bad experiences with contractors led me to essentially give up on my project. Guillermo was sent from heaven to save us, and he approached the work honestly, conscientiously, and as if it was his own home. I will never work with anyone else again.

    Guillermo and Shirley took their time to explain the whole process and answered our questions. It was so easy working with them. Their team is super professional, and the best part is everything happened accordingly to the schedule we set from the start.

    There are not enough positive words to describe GS Complete Builders. They are trustworthy, honest, and responsive. Guillermo transformed our poorly constructed and not-great-looking house into a beautiful home beyond our expectation. Not only is he an expert, his attention to detail is awe inspiring, and he treats your home as though it is his own. The entire team is filled with artists, mathematicians, and magicians. We are so grateful to have worked with GS Complete Builders – they’ve become like family.

    Guillermo and his team performed a complete inside and outside renovation on our outdated home in less than 3 months. Guillermo expertly crafted our “forever home” with his creative ideas and attention to details. We are eternally grateful for the work and a new friendship.
