Winandy Logo


Winandy Greenhouse Co., Inc. company was founded as a sole proprietorship in the early 1920's by Mike Winandy and incorporated in 1929. Our company has been continuously in business since that time through a depression and World War II. The company has engaged in only one business pursuit since being incorporated in 1929 and that is the manufacturing, erection, maintenance, and refurbishing of greenhouses. We also provide wholesale sales of greenhouse maintenance, operating and environmental control equipment, and all types of hardware. That is all we do. We are a specialty company and we normally stay within that specialty. Our company, as a corporation, has been doing greenhouses only for more than 75 years.

We serve the institutional, educational, and governmental markets with specification grade greenhouses and equipment. We can act as either a general contractor, a subcontractor, or a material vendor depending on the dictates of the various biddings. If a project is confined to greenhouses structures only, then we may choose to act as a prime contractor on many occasions. If a project has a lot of other work associated with it, then we choose to bid as a subcontractor to the main contractors or construction manager.

In addition to the above markets, we also work for and with research clients, seed companies, commercial florists and flower producers providing them the same high quality greenhouses and equipment on their projects. Past project references are available for all types of projects.

SUN-MATE® is a registered trademark of our greenhouse skin system of 1, 2, or 3 layers of tempered glass with insulating dead air spaces or the various types of hard surface, greenhouse use structured plastic panel glazing skins. (U.S. Patent #4658859)

Our operating area consists of the continental United States and Canada. We provide our products and services coast-to-coast with greenhouses operating in virtually every state. Our SUN-MATE® greenhouses are furnished in many states each year.
