What Our Clients Say
"I was really hesitant of doing a major remodeling in a short amount of time I had this summer. But I was wrong. Jesus and his crew — especially William — did an amazing job. Credit to their workers for working non-stop throughout the process to get the job done. My house looks amazing, 100 times better than before. I would definitely call Cornejo ICR to work on my next remodeling and highly recommend them to anyone interested in getting their home remodeled."
Matthew T.
San Leandro, CA
"Cornejo ICR redid our kitchen and I couldn't be happier. William was honest about the timeline and budget from day one, and the crew kept the house clean the whole time. It feels like a brand new home."
Diana R.
Stockton, CA
"They handled our bathroom remodel start to finish — demo, plumbing, tile, everything. No surprises, no nickel-and-diming. The tile work is the best I've seen in person."
Robert M.
Manteca, CA
"We added a room and Cornejo ICR made the permit process painless. Showed up when they said they would and finished ahead of schedule. Worth every penny."
