Flooring?

I'm planning to refinish the floors on my house at 2454 E. Frontier Elm. The house was built in 2007 and the floors appear to be engineered hardwood, but I'm not certain the surface layer is thick enough to be sanded and stained. Have any of you had your floors refinished? If so, please let me know if you were able to get the results you wanted. Thank you. Roy Stanley
