Why hire a pro
Benefits of hiring a licensed professional for Electrical Panel Upgrades
It isn't only about the finished result — it's about permits, safety, insurance and what happens when you sell the house.
01
Utility coordination handled
A service upgrade means scheduling Xcel's disconnect and the city inspection in the right order. A licensed contractor owns that chain.
02
No shortcuts inside the can
Correct torque, proper neutral/ground separation, AFCI and GFCI where required — the details inspectors and insurers look for.
03
Documented for insurers and buyers
Some carriers surcharge or refuse to cover Stab-Lok and Zinsco panels. A permitted upgrade closes that file.
04
Capacity planned, not guessed
A load calculation sizes your service for what you'll add over the next decade, not just today.

Electrical Panel Upgrades FAQs
How much does an electrical panel upgrade cost in Denver?
How long will my power be off?
Usually four to eight hours in a single day. We schedule the utility disconnect in advance and work straight through.
Do I need 200 amp service?
If you plan on EV charging, electric heat, a hot tub or a finished basement, 200A is the practical baseline. We confirm with a load calculation.
Is my Federal Pacific panel really a problem?
Stab-Lok breakers have a documented history of failing to trip. Replacement is the recommended fix, not repair.
