Its Better Business Bureau grade is A+. A recent customer said they used the company once when they finished their basement and recently contacted it again about extending the basement; that customer called the pricing very fair. A 2024 customer working toward a certificate of occupancy said the company promptly provided a document they needed for a job done several years before. A 2024 Google customer said the company was a subcontractor for their landlord's project management company and sprayed outside the directed area. That 2024 customer said they spray-foamed over a 120v cord and plugged it back in, causing a short circuit and a fire. That 2024 customer also said they packed up their truck and left before the fire department arrived, and that the owner of Energy Spray Systems was disrespectful when he showed up.
