We hired Corona Excavation to finish our residential construction project and we received a fantastic service from this company. It was the opposite of what we had experienced with the other company we had dealt with before at the start of our project. Corona Excavation's service was excellent for the following reasons: - complete transparency (written quote was specific and there were no cost surprises encountered) - fully reliable - great customer service - excellent business practices -better service cost ( better then others) -great quality of work ( precise and carefully done) - great accountability received from employees and manager - great site supervision and daily manager presence and site review -excellent communication received from manager and employees - employees on site were well trained; Great at their work; reliable; communicated effectively in a friendly manner; they were very professional. We highly recommend this company to anyone (or any company)who requires the services of an excavation company. Greg and Diane read more
