Frequently Asked Questions

How do you handle parts for heavy equipment repairs? expand_more

We work with major regional OEM and aftermarket equipment distributors to source exact part numbers. If you already have the replacement parts on-site, we are glad to install and verify them. Otherwise, Zach will diagnose the failure and source quality parts for installation.

Do you offer Planned Maintenance for our entire machinery fleet? expand_more

Yes! We coordinate planned maintenance schedules around your job site hours so your machines stay serviced without disrupting project deadlines. Visit our Planned Maintenance page for details.

Can you inspect a machine before I purchase it? expand_more

Absolutely. We offer comprehensive on-site pre-purchase inspections before you buy from a dealer, auction, or private seller. Learn more on our Pre-Purchase Inspections page.
