You have 2 options: a) rip it all out it b) live with it as is. If he did not know what he was doing with pouring the slab with relief cuts what makes you think he know what he is doing for a fix?

This usually happens when the workers have a beer for lunch..."jk"

As Millworkman said, most likely it will look even worst.

Here's your contractor asking for help.

We have decided to contact a concrete cutting guy to come evaluate the situation and tell us if he can fix it. we definitely not letting the original guy touch this again.

Oh SNAP! Joseph! Wow. I've never seen the IDENTICAL photos posted from both a homeowner AND a GC with the SAME question: how to fix this! Oh dear. Not a good situation for either of you.

Take a discount on the work (roughly the same amount it would take to fix the issue) and let the original GC walk away.

Waiting on the concrete cutter to give us an estimate, then will deduct it from his final payment. I just hope that it can be fixed!

It can only be fixed with wider kerfs to straighten the lines. If you can't live with that, it's sledgehammer time.

As Joe said, if he runs a tuckpointing blade which is wider it will get a little better, but in the last picture the top portion were he made that curve, most likely you will have to live with it or that portion of the slab would have to be replaced.

Homeowner hired low-bidder, they got what they paid for. Most likely the Handyman was not licensed or insured. Lessons learned on both sides.

Oh no! Those are definitely not great. One thought is maybe to add more cuts so you have smaller squares and then maybe stain it? It would look like tile almost that way. Having more going on might detract a bit from the mistakes. And once you get furniture and stuff on it, it likely won’t be as noticeable. That’s really too bad that he made such big mistakes.

You can grind everything down flat and re-cut the line. 16 grit diamonds will level that.

What license would you expect a concrete contractor to have? I don't think any of the concrete guys I know have any type of license. Heck, one guy I would trust to do a good job cutting doesn't even have a driver's license...for that particular person, the task would be scheduled early in the day! License and insurance do not require actual ability or the willingness to do the work to a high standard.

License and insurance indicates stability and good literacy skills. Quality workmanship and knowledge of the craft indicates experience with the tools and materials and good physical skills. Hopefully you find the person who is skilled in both aspects but most folks skew one way or the other. I like to meet people who team up with others who complement, not duplicate, their skill set.

Yay! Chalk one up for the 'good guys'. So glad we could help. Do you have new photos to share?

Much better! The strong saw cut actually looks better than most thinner cuts. It becomes a 'feature'. I think this can be called a fantastic oopsa.

Looks much better... I'm glad it worked out and now you can enjoy your patio!
