Have had Castro out several times for troubleshooting as well as general electrical work (including outdoor receptacle and fan installation). I have been totally blown away by everyone’s professionalism, personable affect, and attention to detail. Communication is great. Prices appear very reasonable. They were able to diagnose a tricky safety hazard and remedy the situation thoroughly. I cannot recommend them enough!

Specifically I want to say a special thanks to Peter for his diagnostic work and attention to detail. He is also incredibly kind and clearly loves his work and the people he helps. He’s very smart and I trust him fully

It’s a pleasure to work with a service provider that knows how to get customer service right! Castro Electrical worked with me to get a critical electrical upgrade completed on a schedule that was important to me. Even if that meant inserting a job into an already full calendar, modifying the estimate and job specifications per my requirements, or having Peter and Carter (both managers) themselves come out and do the work. This team, together with their boss and owner Paul really differentiates themselves with their flexibility and customer focus while also being excellent electricians who know the job and how to do it with high quality!

Carter from Castro came out quickly to do an estimate and was very responsive throughout the process. He gave us different options for how to do the job, and did not push the more expensive one. Once the job was booked, they were able to complete it very quickly. The electricians were professional and courteous, and did a fantastic job. Will definitely use Castro again for future jobs.
