OneCall Pro LLC — plumbing and electrical expertise, licensed, background-checked and trained, with upfront pricing and no surprise fees
About Us

One dependable team for the systems that keeps your property running.

OneCall Pro LLC was built on a simple idea: homeowners and property managers shouldn't have to juggle multiple contractors to keep the water flowing and the power on. We bring plumbing and electrical expertise together under one roof, so a single call solves problems that used to take two.

Our technicians are licensed, background-checked and continually trained on the latest codes and equipment. We show up on time, protect your space, and explain the work in plain language — then leave the job cleaner than we found it, whether it's a dripping faucet, a full panel upgrade or a general repair around the property.

  • Upfront, transparent pricing — no surprise fees
  • Fully equipped for both routine and emergency work
  • Workmanship you can rely on, backed by a guarantee
