Contractor Lawrence Pao does top quality excavation as well as masonry work at a very competitive rate. I interviewed several other masonry as well as excavation contractors listed on BBB before I hired Pao Excavators. Pao Excavators is licensed and insured. I hired Lawrence to tear down our old carport and pour the slab to build an addition. Tearing down the carport wasn't a straightforward job as the carport was attached to the existing house. He stopped by several times to figure out the best way to do the tear-down with minimal damage to the roof of the existing house. He shored up the roof and was very careful when tearing down the carport. He cleaned up the mess and hauled it to the dump for us. The concrete work was top notch as well. He listened our concerns and did a great job. He showed up promptly and did not stop until the job was complete. He was meticulous and didn't cut any corners. I can rest easy that our new garage has a solid foundation thanks to Lawrence! Highly recommended. read more
