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

After browsing some time to find a contractor that met our standards, we finally had the pleasure to work with Cornejos Builders. From the beginning of the project to the end Alex and his team committed to being consistent with communication in every aspect and was extremely informative when we had any questions regarding the project. They turned our existing garage into a comfortable and livable space which is exactly what we wanted! The garage was converted into an ADU and was completely renovated from inside and out. Not only did it add value to our home but also brought much satisfaction to our friends and families when visiting. It really helped that he was flexible with our budget and was able to compromise on a price with us. The price was very reasonable considering how efficient and outstanding everything turned out to be. We really appreciate someone that is thorough from the beginning and Alex proved himself that he is dynamic, professional and coordinates well to our needs. We are extremely content with the final product and will definitely be considering any future projects with Cornejos Builders.

Overall, my wife and I are happy with our ADU.
I first need to point out CB builder’s strong points: Alexsander and his Father Pancho are knowledgeable and dependable. Their crew, Carlos and Andres are courteous and hardworking. Hugo, the tile layer , takes pride is his work and it was a joy to watch him work. The plumbers used top materials and did professional work. The cabinet and countertop guy are professionals. Cesar, the electrician is knowledgeable and clean.
Now the negative. First, their drywall crew was sloppy. I came in on numerous occasions to correct their work Secondly, cleaning up was a bit of an issue for them. During the four month construction, CB Builders only picked up the trash pile twice. On numerous occasions, I cleaned up after them. The third issue was the one sided contract I signed. Ninety-nine percent of it is written to favor CB builders. I strongly recommended you read it carefully or hire an attorney to explain it to you. This will help you avoid misunderstandings as the project progresses. The fourth issue, and this is important, ask your architect to draw or directly annotate the details regarding the sewer, water, and gas hook up on the plans. My architect did not, and this was a point of contention. I resolved this by hiring a different plumber to finish the hook ups at a 70% savings compared to the CB builders estimated change order. My sons and I, did the asphalt removal, trenching, backfilling, and the concrete driveway repair. It was a major headache and backache for me. However, in the end we are happy with the ADU and CB builder workmanship on the project.

Cornejo's Builders did an amazing job remodeling our kitchen. Alexsander made this experience one of a kind, he was accessible and flexible throughout the process. This guy's knowledge truly guided us to perfect our dream kitchen. He has endless recommendations. The workers were efficient. We appreciate how he handled minor changes we had with professionalism. After getting work done by different General Contractors, Cornejo's Builders definitely sets the bar for the rest. Thank you, Alexsander.

I had the pleasure of working with Alex and his team for a massive home renovation and remodel. What started out as kitchen renovation, grew into two bath remodels, lighting upgrades, interior/exterior paint, a front courtyard, a tankless water heater installation, garage storage/attic creation, fireplace upgrade, and relocation of washer/dryer.

I grew the scope so large because of trust, communication, and watching Alex & his team work of the course of 2 months.

They took amazing care of my home, as if it were their own. Without hesitation, I would call Cornejos Builders. The pricing is fair, you are given many options, suggestions but always remain in control of the process. Alex and his team created my dream home and I could not be happier. Thank you again. Alex is professional, very helpful, has great ideas! Fantastic experience.
