Verbal contract with contractor

[Ross Bernard]

I had about 1250 sqft worth of LVP flooring that I wanted installed in my property. I got a quote from one contractor for $2.25/sqft install, $0.75/sqft for pouring self leveler where needed.

I was referred to another contractor who was going to do my backsplash only. He agreed to match the quote from the other installer, and to install both the floor and backsplash. We agreed to the same price per square foot for both install and leveler.

They installed the floor, but did not pour self leveling compound. Now the floor dips in many areas where it isn't quite flat.

Unfortunately, we only had a verbal contract (which I would never do again). Now he claims that he did not agree to level the floor. I have not yet paid him anything.

My plan is to offer that he fix everywhere it needs leveling, or that I only pay him for the backspash install.

What would you do?
