"Leo went out of his way to meet my concerns about cost, collaboration with my neighbor, and how the fence would look. He submitted multiple bids giving me options as to how to do it and at what cost. He tailored his approach to my needs. His team was easy to work with. The team worked quickly, efficiently, and throughly. The fence looks great!"
