Questions and Answers
My Silver Spring home is older and has flickering lights. Can you help diagnose and fix the problem?
Absolutely. Flickering lights in older homes often stem from loose connections, outdated wiring, or an overloaded panel—common issues we specialize in. As "old house wiring specialists" since 1968, we start with a comprehensive electrical inspection. We provide a detailed report explaining any safety concerns, such as loose connections that can cause power surges or damage appliances. From there, we can perform precise repairs, a rewire, or a panel upgrade to ensure your home's electrical system is safe and reliable for modern demands.
What does your process look like for a full electrical panel replacement or upgrade?
Our process is thorough and transparent. We begin with a detailed inspection of your current panel and overall system to understand your home's specific needs. For over five decades, we've completed more than 2,000 service upgrades ("heavy-ups") without defects. We'll explain why an upgrade is needed—often due to increased electrical demand in older Silver Spring homes—and provide a clear plan. Our licensed electricians perform the installation with meticulous care, treating every connection as critical. We guarantee our work and are bonded, with a $3 million liability policy for your protection.
Do you only work on wiring in historic homes, or can you help with new light fixtures and outlets during a renovation?
While we are renowned experts in repairing and rewiring historic properties, our skills extend to all aspects of residential electrical work. We frequently assist Silver Spring homeowners with renovations and new construction projects. This includes installing recessed lighting, updating kitchen and gallery lighting, and adding new outlets or circuits to meet modern living standards. Our foundational commitment to quality craftsmanship and treating customers like family applies to every job, big or small.
