Customer Reviews

Juan Verde

When I decided to build an ADU on my property, I had no idea where to begin, permits, design, budgeting, everything was completely unfamiliar. That’s when I hired Doza Build Construction, and from day one, Ralph and Mike made the entire process smooth and stress free. They guided me step by step, helping me navigate city approvals and submit the necessary plans with confidence. They provided a clear and accurate estimate, and the final cost was very close to their original estimate any overage came from my own decisions, like upgrading to premium tile for the bathroom shower walls. I had contacted two other contractors who quoted similar prices, but it was Ralph and Mike’s professionalism, transparency, and genuine friendliness during our first meeting and throughout the project that truly set them apart. I couldn’t have asked for a better team to bring my vision to life. I added nearly 749sf to my property a 2 bedroom 2 bath home very spacious with 10 foot high ceilings to make it look bigger. If you need an ADU built the right way with less stress they can help you.

Rajon Smith

We had an excellent experience working with Ralph from Doza Build Construction on our full house remodel. From the beginning, Ralph was professional, communicative, and incredibly knowledgeable. He kept us informed throughout the process, addressed any questions or changes promptly, and made sure every detail was done right. The quality of workmanship is outstanding, and our home feels completely transformed. A full remodel can be stressful, but Ralph and his team made it smooth and well-organized. We highly recommend Doza Build Construction to anyone looking for reliable, high-quality remodeling work.

Ben Quezada

Having bought a home after 15 years, we had a vision to convert our newly purchased gem into a home. We contacted a different contractor, but he didn’t really envision what we had in mind. We were then given the opportunity to contact Ralph, through a family member and sought a second opinion. Ralph and his team listened and delivered what we had envisioned for our now forever home. The level of professionalism, commitment, and communication were impeccable and we are grateful for all the hard work and effort that was given.

Utilized Doza Building for some Framing and Painting at my home. Guys did a great job. After the job was completed they left my home clean and went over all their work with me. Thank you again for your attention to detail.
