“I have had the opportunity to work with Winston Engineering as a member of a project team. The design and documentation process was seamless. The team was extremely professional, responsive and their work was of the utmost quality. When I decided to open a brick-and-mortar business, they were the first call I made to build the project team. Again, they proved very competent in all the ways that move a project forward. The team listened to our needs, produced the drawings before the delivery date they provided and our clearances came fairly quickly even for a submittal during the pandemic. I will definitely keep Winston Engineering as a go-to service provider for our MEP needs.”

Genelle Brooks-Petty, BPC Interior Design

I have worked with Winston Engineering on 3 commercial projects in the city of Compton and one in Los Angeles. I appreciated their professionalism and quick response to me, even when unexpected plan check comments were required prior to pulling building permit. I have already recommended their business services to my business partners and other colleagues. Their fees are competitive. Once when two firms bid on one of the Compton Projects, the bids differed by $100. When the fees are negligible, the contract was awarded to Winston due to trust and professional relationship that had been built. I will continue to hire them for my future MEP engineering needs.

Not only did Winston Engineering prepare the work for a very reasonable fee, the work was completed in less than a week. Although this was our first project using Winston Engineering as our electrical consultant, it will not be our last.”
