The cost to relevel a mobile home fluctuates a lot here in Alberta, Canada.
If you don’t mind if they have insurance, business licence and the proper equipment you can find people offering it for as low as $300 to level a single wide. I get a lot of calls each year a month or so after these people do their work to come and properly do it with 8 or so jacks and a digital water level versus the 2 jacks and bubble level you can have for $300.
We charge anywhere from $900 to $1,200 for basic jobs and as high as $2,000 if you have decks and addition or require additional blocking etc. But, we get the frame within 1/8" throughout and have never broken a window.
We have a cost calculator you can play around with on our site:
