Overview

A premium take on alternator & starter replacement

When the car won't start or the battery light comes on while you drive, the problem is usually the starter or the alternator, and both are exactly the kind of repair a mobile mechanic saves you a tow on. FixBros tests the charging and starting circuits first, because a bad ground or a corroded cable can look like a dead alternator. Once confirmed, we replace the unit on site, retension the belt, and verify the charging voltage before we go.

This service is a good fit for homeowners and property managers who want a clean, professional result without juggling the details themselves. We handle the prep, the finish work, and the cleanup so the space is ready to enjoy when we're done.

What's Included

Every project covers the essentials

  • Charging and starting system tested before replacement
  • Alternator, starter, and related cabling replaced on site
  • Drive belt inspected and retensioned
  • Battery tested after the repair to confirm it survived
  • Quality remanufactured or new units, your choice
  • Ideal for no-start and battery-light situations
