You may want to consult with the local authorities to see if its even possible. I know of a case where it simply wasn`t due to the logistics of upgrading the feed. Came as a shock - no pun intended - to the buyer. Property is/was a wartime home. Still has 60 amp today.
For what it is worth, my understanding is that the service feed to your home is actually alluminum wire. There is no concern re: amp amount and alluminum wire. Issue is overfusing the alluminum wire. Unsurprising, when you overfuse copper wire, you have potential for problems as well.
Have your electrician inspect the receptacles and switches. Over time, alluminum wiring, at these connection points expands and contracts - which could cause arcing. So in short, there`s a little more maintenance on alluminum wire than copper.
Another post said to go to 200 amps. Its an additional $200. In my area, Waterloo, $1200 for 100 amp. $1400 to go to 200 amp. Of course, if I was duplexing, I would go the separate meter route so you can download utility cost to tenants in future.
