What Rowland Heights Homeowners Say About Us
Edith Rangel
Alex is very responsive and easy to talk with. He was highly endorsed by a satisfied coworker with whom he completed a roof project. Alex and his team Cornejos Builders Inc completed our roof project quicker than expected.
He came on-site and explained thoroughly the work they have done to our roof. The workers are very professional as well, they cleaned up after the job was done, and it was not messy at all. I will be using Cornejos Builders Inc in the future

We couldn’t have asked for a better contractor to work with than Alex.
We were needing our home remodeled in a very short window of time and Alex and his crew were always on schedule and in touch with us throughout the whole remodel.
We would definitely use them again.
