Jenna Laricchia​


Cornejos Builders Inc did excellent work for my kitchen remodel project.

I really appreciate Alex efforts in fulfilling my goals, not to mention I had fun working with the team who gave me excellent quality service and ideas for my project. I am extremely satisfied; not to mention the reasonable timeline to finish the job with no hassles.

I wish Cornejos Builders Inc great success! I highly recommend Cornejos Builders Inc to anyone who is looking to get construction work done.


Yahritza Orellana​


Had a truly great experience with Alex. Cornejo’s Builders just completed converting my crawlspace/basement into an ADU (studio with new bathroom and kitchen).

What made the experience even more valuable was that the owner himself (Alex) came over for a consultation. Other companies just send their sales reps and most of the time they don’t even know anything. Feeling important is always a positive I can’t wait to work with them again.

I highly recommend them. You can tell Alex is passionate about what he does, his clients, and his company.
