Upgrading a Circuit Breaker box to 200 amp

Let me start by saying I DO NOT MESS WITH ELECTRICITY ONE LITTLE BIT! Has my complete RESPECT and FEAR! I will change an outlet/switch/lighting fixture etc, BUT I AM NOT under ANY circumstances doing anything with the breaker box EXCEPT throw the breaker when it pops.

I was wondering, (I know you can only give the roughest of estimates) "AROUND" how much would it cost to upgrade from 100amp to 200 amp?
I live in Philadelphia Pa if that helps. There is some knob and tubing still in the house, but the big issue is the way the circuit were wired. If I trip a breaker in the kitchen because I was running the microwave and the iced tea maker at the same time, my son loses 3 outlets and ceiling light in his room (upsairs), the ceiling fan in the dining room goes, but the outlest stay, not to mention the two outlets in the kitchen. VERY VERY WEIRD!

I guess with upgrading the box I would also have to have the electrican seperate the lines to their own breakers too?

Thank You

Two separte issues, the panel and the tripping circuits.
First question is why upgrade to 200 amps? Are you adding some sigificant loads? Around here it would cost about $2000 for a 200 amp standard panel instal.
Rewiring the circuits in the house is totally dependant on how difficult it is to fish wires and the house layout.

New circuits may solve your problem without a panel upgrade. You are trying to do too much on too few circuits.

This site is for DIY, not cost estimates
Costs vary by job, area & what can be seen visually inspecting the current installation

Get several estimates & check references
Thank you
