I want to get a garage this Spring which, according to Phil this morning, is right around the corner. I want to put it on a 6" 4000 psi concrete slab probably 24X28 give or take a few feet. I'm interested in cost for prep work (almost no excavation needed) pouring and finishing.

Anyone have one done recently or in the business?

I'm interested, too.

For a really professional job...it is pricey. We had our whole driveway and widened a few years back I was shocked at the price.

You can get Billy Bob and his cousin Jimmy out and you'll have cracks in a few years. And you'll have people here tell you how easy it is to do yourself....but....it's not. You've got have the right tools and the know-how.

Or you can lay down some pretty serious coin and get a job that will last the life of your garage.

You are looking at thousands of dollars.

Construction Project Manager here.

Ballpark you are looking anywhere from $2000-$3000 depending on material costs and the quality of labor you hire.

I'm thinking you're looking at about $4k. It all depends on the price of rebar, concrete, and labor in your area. Also, if you live where you will have to get a permit or inspection the price will go up.

Labor is cheep right now because everyone is trying to underbid everyone else.

Still, prepare for $4k, give or take.

I build pole barns in TN. The average price for a 4" thick pad with an 8" turndown around the outside is $3.50/sq ft plus gravel.

I put in a 15x21 8" pad this fall. wire re-enforced, tooled joints, stamped and dyed.

7yrds of concrete came to just under $600. labor was just under $1000 for prep, pour, finish and sealing. This was a "weekend job" for the 2 guys, not through a business (they work as concrete contractors during the week). So i got quite a deal on the labor. add to that $300 for the mini excavator and it came out to right around $2000. You have to figure in cost of gravel too. I got mine for free.







It turned out excellent. I've had several people ask me the how and where of the "slabs of granite."
