Frequently Asked Questions
My smart TV and router keep getting fried during East Riverdale thunderstorms. Is this a Pepco problem or mine?
While Pepco manages the grid, final protection for your electronics is your responsibility. Our area's moderate surge risk from seasonal thunderstorms means transient voltage spikes are common. A whole-house surge protector installed at your main panel is the most effective defense, absorbing those spikes before they can travel through your circuits and damage sensitive 2026-era electronics.
My power comes in on an overhead wire to a mast on the roof. What should I watch for?
Overhead mast service, common in our area, requires periodic inspection. Look for any sagging or fraying of the service drop cables between the pole and your house. Check the masthead and conduit for rust, and ensure the connection is secure. Heavy ice accumulation or falling branches can damage this assembly, which is your home's main electrical lifeline.
Do I need a permit to replace my electrical panel in Prince George's County?
Yes, a permit from the Prince George's County Department of Permitting, Inspections and Enforcement is legally required for a panel replacement or upgrade. As a Maryland Board of Master Electricians licensee, I handle that entire process. The work must comply with the 2023 National Electrical Code and will be inspected to ensure it meets all safety standards for your home and family.
I want to install a heat pump and EV charger, but my house has an old 100-amp panel. Is this possible?
It's a common goal, but a home with its original 100-amp service from 1960 is almost always undersized for those additions. Furthermore, if your panel is a Federal Pacific brand, it presents a significant fire hazard and must be replaced before any upgrade. A full service upgrade to 200 amps is the necessary first step to safely support a Level 2 EV charger and modern, efficient heat pump systems.
Why do my lights dim when I turn on the microwave in my Riverdale Park home?
Your home's original 1960s cloth-jacketed copper wiring, now 66 years old, was designed for far fewer and less powerful appliances. Modern circuits in a 2026 home handle microwaves, computers, and HVAC systems that draw much more current, stressing the old wiring's capacity and insulation. This can cause voltage drops, seen as dimming lights, and increases the risk of overheating at connections.
We have a lot of mature trees near our home. Could that be causing our flickering lights?
Absolutely. The rolling piedmont terrain around the Riversdale Mansion often supports a heavy tree canopy. Overhead service lines running through branches can cause interference, and during storms, falling limbs are a primary cause of service drops and outages. If the flickering is persistent, it could also indicate a failing connection at the masthead or where the service entrance cables connect to your house.
My power is out and I smell something burning near the electrical panel. Who can get here fast?
For an emergency like that, call us immediately. We're based near the Riversdale Mansion and can typically dispatch a truck within minutes, using the Baltimore-Washington Parkway (MD-295) for a direct route to most Riverdale Park addresses. A burning smell often indicates a failing connection or breaker, which requires immediate, safe disconnection and professional diagnosis to prevent a fire.
How can I prepare my home's electrical system for a summer brownout or an ice storm?
For summer AC peaks, ensure your panel and breakers are in good condition to handle the load without overheating. For winter ice storms that threaten power loss, a professionally installed generator interlock kit and standby generator provide safe backup power. Never use a portable generator without a proper transfer switch, as back-feeding the grid is illegal and deadly for utility workers.
