Replacing sidewalk section

I have one section of sidewalk in front of my house that is severely lifted.
I already ground the edge myself once but it's time to cut the tree roots underneath and replace.

I have done a fair amount of DIY concrete work but I may want to have this done by a pro so it's done fast. About how much would this cost? It's just one 3' section that needs replacing.

Also, I see a thin vertical plastic strip embedded between some of the sidewalk sections at the control joint. is this some kind of isolator? I don't think it goes all the way through the slab because I see no movement at these joints.

Cost will depend on going rates in your area, how much site work needs to done and the size of the pour. Demoing the old slab and hauling away the waste could equal the cost of pouring the new. Since you're only doing a 3' long section you'll probably run into minimum fees. Around here 2 yards is the minimum many ready mix companies will deliver without an additional delivery fee so it may be cheaper to mix on site.

Got a picture?
Is this section between two joints?
Is it cracked or just lifted?

A reasonably handy guy could remove and replace such a small slab in a day. Keep in mind that batching, placing and finishing will make for a full day, and can present challenges if you don't have concrete experience.

Batching and placing 6 bags of Sakrete, sweetened with Portland cement, could be done manually in a wheelbarrow, and would involve a total material cost less than $50. That includes forms which could be reused later. Getting rid of the old, broken out concrete is often done around here creatively by guys on Craigslist, advertising as "free (for-the-hauling) urbanite."
