    No sooner had I called, Addie in the office, realized our dilemma with no water, and dispatched the technicians very quickly. Upon arrival, Calvin was able to diagnose the situation and immediately fixed it. The level of professionalism and Care we received from the whole team was amazing. I will be a Lavallee customer for many years to come because of what they did for me.

    Corey and Jimmy saved me the $4000 cost of a new heater. They were amazing and in no time they had my pool heater going. I cannot imagine calling any other company. They went over and above to squeeze me in because I need the pool for health reasons. A million thanks.
