"We hired Ace Restoration and Construction Inc to do our kitchen remodel. My kitchen was so outdated. I had an idea of what I wanted but was also unsure of some of the things needing to be done. They helped us through the whole process. It was so fun to design it together and then watch it all come to life! If you?re going to do work on your house I for sure would recommend Ace Restoration and Construction!"

Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:
In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
