    OUR STORY

    Industrial Steel & Boiler Services, Inc. (ISB) was founded as a small shop in 1991 by William O’Neil and Gayle Rae.  ISB rapidly expanded to a full service, one-stop-shop for industrial, commercial, and power plant solutions.

    Alex Korobkov began his career with ISB in 2001 as a boilermaker and became the owner in 2018.  He learned every aspect of the business from the ground up through mentorship with Bill and Gayle.  Alex’s experience in hands-on repair, equipment maintenance, ASME certified welding, and directing operations gives ISB a unique competitive advantage.

    ISB is dedicated to our hard-working team members and our loyal customers which is why we will always treat both like family.  We deliver exceptional, dedicated, expert service because we love what we do.

    What our customers have to say about us

    “Had a great experience with ISB when our office boiler went kaput. Called them up and they were super quick to respond. The techs were pros and seemed to enjoy what they were doing... fixed the pressure issue in no time, and even gave us some tips to keep it running smooth. Left everything clean too. Def recommend them for hassle-free and expert boiler repair!”

    “Before, I used another company, and it was a never-ending story. They'd fix it, then boom, something else would go wrong, and they’d be back charging me again. Total headache. I tried these guys, Industrial Steel & Boiler Services and they sorted it out in one go. No repeat visits, just one and done. It’s been running smooth for six months now. they know their stuff and dont mess around.”
