  I had the pleasure of Sam’s assistance this morning with my tripped breaker. I am a female homeowner and Sam walked through it to get my power turned back on. STS is stored in my phone for future electrical issues. Ladies don’t hesitate to call them!

  Excellent workmanship, speedy, polite and accommodating.  I’ve used them before and they are definitely recommended.  Also, they stand behind their work.  Any issues and they make sure it is right.

  Both electrians were excellent and worked efficiently. Replaced 3 ceiling fans, 6 wall outlets and repaired 1 light switch. They found that one of the electric boxes for a ceiling fan needed more stabilization and had the equipment on hand to fix the problem.
