I am a licensed, bonded, and insured General Contractor with an extensive background in design and construction. I do not just talk the talk, I walk the walk, having physically labored in trades ranging from tile and plumbing, to foundation and framing. To this day, there is seldom a project I will not roll up my sleeves for, be it setting lines for a home addition, or laying out complex tile patterns to be reproduced by my team. I received my Masters in Architecture (M.Arch) from UCLA, where I graduated with distinction. My commencement thesis focused on the California Accessory Dwelling Unit (ADU) legislation, a space that I have become a leading expert in. Building home additions and creating additional housing in the form of ADUs is my lifework: there is nothing more rewarding than delivering a finished project to a client. If you are contemplating a home addition, major renovation, or building an ADU, give me a call. I look forward to hearing from you.

"I recently hired Sklar Construction for a major renovation on my home in Culver City, and I was blown away by their service. From start to finish, they were professional, detailed, and truly cared about my project. The team was fantastic at keeping me updated every step of the way. They answered all my questions and made sure I felt comfortable with the progress. They finished the project on time, and the quality of their work was incredible. My home looks amazing, and I've gotten so many compliments on the renovation. What really stood out to me was how Sklar Construction listened to my ideas and offered great suggestions to make my vision even better. They were committed to delivering top-notch results, and it shows in every detail. I highly recommend Sklar Construction. If you need a renovation done right and want to work with a team that truly cares, go with them. You won't be disappointed!"

Licensed & Bonded Contractor Specializing In Fire, Water, & Mold Damage Remediation & Restoration. Accessory Dwelling Units (ADUs) & residential & commercial additions. Veteran Owned Small Business With 45+ Years Of Family Experience As Pasadena Based Designers & Builders

"There was mold in my closet and I knew it was probably not a great idea to live with it. Chris Gibbons gave me clear and useful information about the options and trade-offs and broke through the noise. Seems like the other "experts" and insurance people I talked to were just adding confusion. Recommend Paul Davis Pasadena highly if you have mold."

"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."
