When your equipment goes down, you need it back up and running — fast, and done right. At Substrate Technology, our repair service is backed by the same expertise that goes into everything we do. When you send us a machine, real surface-prep technicians work on it — people who know this equipment inside and out — not a general repair shop guessing their way through it.
Equipment We Service
We repair and service a wide range of concrete surface prep equipment, including:
- Concrete floor grinders — Prep/Master and other brands
- Shot blasters
- Dust collectors and vacuums
- Hand grinders and edgers
- And more — if you’re not sure whether we service your machine, just ask
Whether it’s a machine you bought from us or from someone else, we’re glad to help get it running again.
How Our Repair Process Works
We keep the process straightforward and transparent:
1. Send us your machine. Get in touch to arrange bringing in or shipping your equipment. We’ll let you know what to expect.
2. We evaluate it. Our technicians assess the machine and diagnose the issue. An evaluation fee applies, which covers our technicians’ time to properly diagnose your equipment. If you proceed with the repair, that evaluation is part of the job.
3. You get an estimate. We’ll provide a clear repair estimate before any work begins. Nothing gets done until you approve it — no surprises.
4. We make the repair. Once you approve, our technicians get to work using quality parts, and we test the machine before it goes back to you.
5. Your machine comes back ready to work. We’ll arrange return shipping or pickup, and take payment by secure invoice link or over the phone — whatever’s easiest for you.
Nationwide Service — Ship It to Us
We service nationwide. No matter where you are, you can ship your machine to our shop for repair — contractors send us equipment from all over the country. Typical turnaround is 7–10 business days once your machine is in our shop, unless a needed part isn’t immediately available — and we’ll let you know right away if that’s the case.
Genuine Parts and Real Expertise
We stock parts and know these machines, so repairs are done right and done to last. And because we’re surface-prep experts — not a general repair shop — we understand how your equipment is actually used on the job, which means we fix the real problem, not just the symptom.
Factory-Trained, Certified Technicians
Our technicians aren’t just handy with tools — they’re Lavina Certified, factory-trained and certified to service Lavina equipment to the manufacturer’s standards. That certification is your assurance that your machine is being repaired by genuine experts who know it thoroughly, not a general repair shop working it out as they go.
Our Repair Warranty
We stand behind our work. Repair labor is warranted for 180 days against defects in workmanship, and installed parts are covered by the applicable manufacturer’s warranty or 180 days, whichever applies. Our warranty covers the specific repair performed; it doesn’t cover wear parts, normal wear and tear, new or unrelated issues, or damage from misuse. Full warranty terms are provided with your repair.
A Few Things to Know
- Evaluation fee: An evaluation fee applies whether or not you proceed with the repair — it covers our technicians’ time to diagnose your machine. If you move forward, it’s applied to your repair.
- Picking up your equipment: Once your repair is complete (or if you decline the repair), we ask that you arrange pickup or return shipping promptly. Complete terms are provided at drop-off.
- Machines we didn’t make: We’re glad to service equipment from other manufacturers. For those machines, parts availability and lead times depend on the original manufacturer, and we’ll keep you informed.
