    Considered for Insulation Work

    The bid only included two of the four ask. I wanted plywood installed in the attic and the attic sealed off from rodent infestation.

    My experience with Astounding Construction was fabulous. They were very professional and did not waste time. I bought a property on a hill in Los Gatos and they built the home from the ground up just in time for my child to go to school in one of the best school districts in Silicon Valley. Definitely would recommend and use again.
