Service & Repairs

When your equipment goes down, you need it back up fast — and you need someone who actually knows the machine. Our technicians service and repair concrete surface prep equipment of all kinds right here in our shop, and contractors ship their machines to us from all over the country. We bring something a parts counter can’t: real hands-on expertise. We repair any brand — and we’re factory experts on the machines we know best. Call and talk to a real surface-prep expert, not a call center.

WWhat We Service

We repair any brand and just about any machine you run, including:

  • Floor grinders and polishers
  • Shot blasters
  • Dust collectors and vacuums
  • Hand grinders
  • Floor scrubbers
  • Swing machines
  • Scarifiers
  • Burnishers

If it preps, grinds, polishes, or cleans concrete, there’s a good chance we can fix it — call and ask.

Certified Where It Counts

  • Lavina® Certified — our techs are factory-certified to repair Lavina machines, so your Lavina is in expert hands
  • Prep/Master® Experts — we build the Prep/Master, so no one knows it better; from routine service to major repairs, you’re working with the source

How It Works

Sending us a machine is simple:

  1. Call or email us with your contact info and a description of the problem
  2. We issue you an RMA number to reference your repair
  3. Ship your machine to us — we’ll tell you exactly where and how. Or if you’re local feel free to drop it off.
  4. We diagnose it and send you an estimate — no work begins until you approve it
  5. We repair it and ship it back, backed by our warranty

No surprises: you approve the estimate before we start, so you’re always in control of the cost.

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.

Backed by a 1-Year Warranty

We stand behind our work: every repair we make is warrantied for one full year. When your machine comes back, you can put it right back to work with confidence.

Why Bring Your Repair to Us

  • Real expertise — certified, experienced techs who know these machines inside and out
  • Any brand — one shop for your whole fleet, whatever you run
  • Estimate first — you approve the cost before any work starts
  • 1-year repair warranty — we stand behind every repair
  • Straight answers — talk to a person who’s actually worked on your machine, not a call center

Parts on Hand

We stock and sell parts for the most common machines we repair, so the fixes we see most often move fast. With the huge range of brands that come through our shop, we can’t stock everything — but if we don’t have a part on the shelf, we’ll source it. Ask us about maintenance kits and replacement parts to keep your equipment running between repairs.
