You would be highly advised to learn how to do basic plumbing, electrical, and renovation tasks yourself in the US as well. The cost savings is enormous. Finding a quality contractor, in addition to being expensive, can also be very hard - there's plenty of people doing plumbing or electrical who might be licensed and everything but are grossly incompetent or never finish jobs.
A lot of stuff in the US is absurdly easy, as well. For example, in my area, pretty much all plumbing is PVC or PEX. Anyone on HN can learn very quickly how to work with this stuff and it's very cheap. There are very few repairs, for example, you could ever need to do that would cost more than having a plumber just show up and look at it - even accounting for buying tools.
