What I like about this place is that the staff is well informed on their products. They sell what they know and they will help you out on your projects. They sold me concrete finishing aid such as Day 1 and helped me get such amazing cure and seals for my concrete jobs. Everything from the basic stuff for everyone's needs to the quality products that I use for my stamped concrete. Appreciate that their staff for helping me out pick the quality products for my jobs. Will be coming here more often.

I’ve been a customer of Contec Supply since early 2018, when I first epoxied my basement floor. At the time, I had never worked with epoxy before, and honestly, I was a bit overwhelmed. But Duane made sure I had help every step of the way. His support was absolutely invaluable—I could reach out with questions and he was always available and willing to guide me through the process. Now, seven years later, I’m refinishing the same floor, and there’s no question where I’m going for my supplies. Contec Supply has earned my trust, and I wouldn’t go anywhere else. Quality products, outstanding service, and real expertise—you can’t beat that.

This place is great, no "secret handshake" required for great service. They always know who I am before answering the phone even-though I'm just a small customer. Always take great care of me and are very familiar with the products they sell.

I can’t imagine how I could’ve accomplished a great turnout with sealing my garage floor if it weren’t for Duane’s help. I’m astonished by how great of product and customer service I received.

Contec Supply is by far the most personal business I’ve been to. All of the Contec team is amazing at getting the products you need for your job. Duane is a scientist in the concrete world, and will always get you your products and more. He is very passionate about his business and all around a great guy. This is why I’ve been buying from them for over a year now, I would hands down recommend Contec to anyone looking to do a DIY project or massive custom homes builds. From counter tops forms, to massive cement overlays to a simple concrete waterproof spray, Epoxy and multiple flake choices to choose from Support your Local Business I’ve gone to a few seminars of theirs and those are super helpful to those looking to expand there business..

I would HIGHLY recommend Contec and the owner Duane. He went over the top in helping me (a rookie) understand how to prep and apply his product. Stayed at least an hour and a half after closing to make sure I understood how to do everything correctly. The product is fantastic, and my garage floor turned out AMAZING!!!

Contec Supply is fantastic supplier of concrete coatings, sealers, and information. Duane has been in the industry for 20 plus years doing jobs himself. Duane is always happy to share his advice and experience to contractors looking for new avenues to expand their trade and home owners looking to do a diy project.
