The team did a great job with a tricky installation in our corporate office space and they also managed to do a variety of projects in our former offices. We were always very satisfied with the team and the work. I can confidently recommend them for any projects.
Ron Moravek
CEO Sport Ninja Inc.
The team did an excellent job listening to our concerns and answering our questions. This was a challenging project as this site was an active Bank branch location and so security, the municipality and the neighboring landlord were involved.
 Thank you to the team for such an amazing job!

We have been so happy with the renovations your team helped us plan and execute that we find it hard to want to move anywhere else. Everything here is just the way we want it. We were living in our LaQuinta home and communicating by email and photos. A very relaxing way to experience a complex project. Thanks so much!

I have had the pleasure of working with Costo Construction several times since being introduced by my realtor. Little did I know how valuable of a partnership and trusted resource they would be over the years. I highly recommend the Costo’s and their family business for their integrity, outstanding workmanship and exceptional customer service. They are a gem.
Jennifer Bender
Director, Client Services.
We are really happy with the work. They met the schedule they had presented at the outset. We really appreciate their diligence in providing a detailed estimate. Their attention to detail was most impressive, noticing or correcting details we would never have noticed. They exercised great management skills, utilized top notch trades and did an excellent job coordinating with our front gate staff. We highly recommend them and without hesitation, we would retain them again in the future.

Evan Hsen
Real Estate Developer, San Francisco, California
The work was completed to a very high standard and even the smallest detail was not overlooked. It was a pleasure to have the workers in our home, they were extremely careful and all sub trades were met outside, instructed on parking, etc. and were brought in with thorough instruction. We were always informed on what to expect and everything moved along according to a very tight timeframe. The project was completed on time and under budget and we would highly recommend the Costo team!

When we needed the help of a construction expert, we were referred to Costo Construction.  From the moment we met, the Costo team has been nothing short of receptive, helpful, and thorough throughout the entirety of our project.  We have never felt more comfortable taking a step back to let this group of professionals handle business – OUR business.  The experience has been so pleasant that we are more than happy to refer them to our friends for future work.  These guys are the real deal!

Hands down, Costo Construction Corp is the best construction company that I have worked with. It’s refreshing that a GC in the Coachella Valley actually know what they are doing! They are professional, have a great crew, and get the job done right.
