OUR Expertise

Open Molding
​The most common method of production where fiberglass is applied using a "chopper" gun.
Closed Molding
​This method uses dry fiberglass cloth that is placed between two halves of a sealed mold.
Hand Lay-up
​Hand lay-up uses fiberglass cloth that is saturated with resin and laid into the mold by hand.

Pattern Work

Carstens is a fantastic partner for our big fiberglass projects, ranging from OEM boat hulls to shower pans, and this giant can in the middle. We have never had an issue with their quality, and can’t say enough about their integrity.

I had a fair amount of cosmetic work done on my boat. It turned out amazing. I am in the process of restoring another boat. The easy part is know the fiberglass work will be done at Carstens and will be high quality. Jake and Scottie make my life easy!! We also use them for some units that come in to our shop and need glass work. Always easy to work with on scheduling.

Damaged the back and keel of boat when taking off the trailer (it fell off onto the cement boat ramp). Brought it in to Carstens for repair. Scotty not only did a fantastic job, he did it in an unbelievable time frame and at a reasonable cost. Good vibes seem to be the norm around here. I've found my fiberglass repair nirvana.

Carstens Industries, Inc. is a very well organized, tidy and fiscally well managed facility. They are deeply concerned to provide a clean and healthy work place for their employees, and this level of concern is reflected in the quality of their product. I would highly recommend them as a reliable and trustworthy vendor.
