Cement Contractor License?
 
I was going to hire a contractor to pour a cement patio. What type of contract do I need to provide and sign? I couldn't find anything online. I assume it can be a simple document that indicates that the work is done to the specification provided. It will take one day to do the work. I have a work order that shows the size of the patio, but not sure if that is enough along with the verbal discussion I had.

Also, what is a minimum warranty time that should be provided on cement work. I saw a few websites stated 2 years.

oops. I used the wrong title.

I was suppose to put something like "Is a contract needed for a cement contractor?"

oh well, hopefully I get some responses.

Thanks

Your contractor should be providing the contract for you to sign.

Be sure to read it carefully and make sure that everything you're expecting is outlined.

A contract is a "meeting of the minds" so after reading the document there should be no confusion by anyone on what exactly is going to be done, for how much and when. Including the "what if's"...what you'll be charged for extra work that may present itself do to unseen conditions.

Btw, it's a Concrete Patio, Cement is just one of the ingredients.

The contractor didn't indicate that a contract would be signed so I was going to develop a simple one that covered the work that will be done, payment, timeline and liability. We verbally talked over everything (it will be a one day job, payment schedule, date) so nothing complex, just laying a concrete patio. I got a work order document that states the size, material, etc to cover the work that will be done, but doesn't have a clause about liability which I wanted to add.

Agreed. The contractor shall provide the simple contract for the scope of work. As far as warranty, you cant really offer that on concrete. Most concrete cracks eventually. What you need to have in the contract is something that states the following:

"Contractor shall install a tamped stone/sand substrate no less than 3 inches"
"Contractor shall saw cut expansion joints after concrete has set"
" Contractor shall install wire remesh"

These three things are used to prevent any cracking or settling.

Thanks for the insight.

The contractor indicated 1 inch aggregate base, which I assume is the stone/sand substrate. I think the 1 inch is too little. I read that some places doing 4 inch, but not sure if that is overkill. Is 3 inches a minimum or could it be 2 inches.

Most, if not all states, require at least a one year warranty on all contracted work, whether you know it or not. If you can't get you're work through the first year without failure, somethings wrong, and the customer deserves better than this. Can't speak for others, but good practice, EXPERIENCE, and honesty work should produce concrete that performs well for decades........

The contractor is likely referring to the size of the aggregate when saying 1". The industry minimum is 4", and more is certainly better. I'd suggest shopping around for another contractor who will give you a decent contract and scope of work. Keep looking until you find the right fit.

I'll check around, but I think California is slightly different. The weather is pretty mild compared to other parts of the country.

Yeah, he's referring to the aggregate size. A 1" minus (all rocks will fit through a 1" screen, with smaller aggregate in varying sizes/percentages that is optimized for drainage and compaction) mix is probably what he'll use for the grade. That's good, though, I've seen a lot of guys that will just dig out the lawn and dump concrete right on the dirt.
