About Trost Plastics

In 1961, Arthur Trost started a small feed and fertilizer business called Trost Feed & Supply. While visiting a supplier on business, he discovered they were starting to manufacture and sell vinyl fencing. He felt this would be a great way to diversify his business and in 1988, Trost Plastics was formed. Arthur’s children, Dennis and Ellen began to see the potential of vinyl fencing and initiated the practice of buying vinyl material in profiles and bulk to manufacture fences and other specialty items, which allowed them to provide a higher quality product to their customers. In the process, Trost Feed & Supply was downsized and eventually dissolved in the mid-1990’s, but Trost Plastics continued to grow as an industry leader. Dennis’s nephew, Justin Garleb, started working on the fabrication floor in 2002 and over the years moved into project design and sales. Justin purchased Trost Plastics in 2018 to carry on the family reputation of high quality products & service.

“I really enjoyed my experience with Trost Plastics. I called them to come out and give me a quote on installing a fence. They were very eager to help me and understood what I wanted. They took in-depth measurements then gave me a quote that day. They were the most reasonably priced and offered the best fence that I could find on the market.

I would not hesitate to ever call this company again for any of my fencing needs. Everyone that I spoke to via phone or in person was professional and I truly felt like a valued customer. My dog and I could not be happier with our new fence!”

Trost Plastics was a joy to work with. The folks who came out from Trost were friendly, patient, and very knowledgeable.

They took their time to understand what my needs were, walked the property with me, provided several options and discussed the pros & cons of each. All in all, it was like having a relaxing conversation with a neighbor.

I was so impressed with their professionalism, experience, and knowledge that I went with them. They arrived on time, finished the work in one day, and with very minimal disruption to the yard. I would highly recommend this company.”

“Thank you and your crew for the new and beautiful railing & spindles. My wife and I are most pleased.”

Over the years I’ve made several purchases from Trost Plastics. It all started with perimeter fencing around the home, a Gazebo and flower box. I’ve added more fencing, a specially built wide staircase to include handrails, trellises, a privacy section to conceal air conditioner, a privacy fence around patio perimeter and recently placed another order.

I give thanks to Dennis, Janet, and Ellen for providing years of quality products and keeping customer satisfaction a priority. In addition, I give thanks to all team members for supporting customer satisfaction by their dedication to maintaining high work standards.”

“We have used this provider previously at another residence and called them first for this job. They are very professional people and always get back to you very quickly.

The materials came in on time and the workers worked quickly to get the job installed even in freezing weather! They cleaned up all materials and left our property in great condition. The workers all know exactly what they are doing and work quickly and efficiently. I would recommend them to anyone wanting fencing installed!”
