Cobra Plumbing & Gasfitting Ltd. was established by Gorden and Loretta Sonnenberg of Wetaskiwin Alberta in September of 1975. The main focus of the business in the early years was residential and commercial plumbing and gasfitting. Through the years the company worked diligently to deliver quality and efficiency to its customers. Not long after getting established, the company started to offer private sewage treatment systems to its list of services. Over the past two decades Cobra Plumbing has increasingly expanded its excavation operations and has recently moved into the concrete market.
