Costello Electrical Service - Bryn Mawr's Reliable Electricians

Our inspections are thorough safety checks. For electrical, we examine your panel, wiring, outlets, and grounding systems, paying special attention to older homes in the area. For plumbing, we check for leaks, water pressure, and the condition of pipes and fixtures. In both cases, we provide a clear, detailed report of our findings and any recommended repairs, which we can email to you directly with our paperless invoicing system.

Absolutely. Nuisance trips in arc fault circuit interrupters (AFCIs) are a common issue in local homes with aging wiring or shared neutrals. Our experienced electricians can pinpoint the cause—whether it's a specific appliance, a wiring fault, or simply an outdated breaker model. We provide reliable solutions to restore stable power to your circuits while ensuring your home's electrical system meets current safety codes.

Our long history in the community means we prioritize trust and reliability. You'll work directly with our local, mobile technicians who have decades of combined experience. We streamline the process with convenient, modern touches like emailed invoices and mobile payments, but the core of our service remains the knowledgeable, personalized attention you'd expect from a neighbor who has been serving Bryn Mawr families for generations.
