Our Story
Castaldy Electrical Services was founded on a simple principle: every family deserves safe, reliable electrical work done right the first time.
What started as a one-man operation over 22 years ago has grown into a trusted residential electrical contractor serving the Denver metro area — from Centennial and Lone Tree to Highlands Ranch and beyond.
We specialize in high-end residential remodels, custom electrical installations, tenant finish projects, and smart home integrations. No job is too small or too complex.
Our reputation is built on word-of-mouth referrals from satisfied homeowners who trust us with their families' safety. That's a responsibility we take seriously every single day.
