"They did a phenomenal job. Great customer service. I asked about a cleaning on Wednesday and they came out two days later. Super fast and price was excellent. Will be using this locally owned company from now on."

"We recently hired Grease Monsters of San Antonio for a vent hood cleaning, and they absolutely delivered. Fast, efficient, and incredibly thorough — left our kitchen ventilation system spotless. Professional team, arrived on time, and worked with precision. Highly recommend, we'll definitely be using them again!"

"We have used Grease Monster several times and they always do an excellent job. Quality cleaning, service and professionalism. Will continue to use. They even travel an hour and a half to get to us after we closed for the day. They cleaned through the night so we could open at regular hours the next day."
