Repair vs. Replace

Many opener issues�stripped gears, misaligned sensors, worn trolley assemblies�are repairable for less than a replacement. If your opener lacks modern safety or convenience features, we price both options so you can choose what makes sense.

What We Service

  • LiftMaster, Chamberlain, Genie, Craftsman, and other major brands
  • Chain-drive, belt-drive, and wall-mount (jackshaft) systems
  • Wi-Fi setup, myQ app integration, and camera add-ons
  • Keypads, remotes, safety sensors, and low-voltage wiring

When Replacement Makes Sense

Upgrading can add battery backup, LED lighting, smart features, and quieter operation. We install openers to manufacturer specs, program accessories, and walk you through every control before we leave.
