Mark did a fantastic job upgrading our electrical panel in Clermont, CA. He explained everything clearly, worked efficiently, and made sure everything was up to code. The whole process was smooth and stress-free. Highly recommend Mark for any electrical work!

Mark did an excellent job at our home. He handled the electrical work professionally and made sure everything was safe and working perfectly. On top of that, he also took care of a few handyman tasks we needed done, and everything turned out great. He was punctual, respectful, and cleaned up after himself. It’s hard to find someone reliable like Mark these days highly recommended!

Mark is a reliable and honest professional whose work is excellent and reasonably priced. He always cleans up after himself, which is why I consistently hire him.

I've had the pleasure of working with Mark Steinbarg Construction on several electrical projects in my home, and I couldn't be happier with the results. Mark is the kind of professional every homeowner hopes to find -- incredibly knowledgeable, meticulous, and deeply dedicated to his craft. Over the course of our projects, Mark has installed recessed lighting, replaced electrical receptacles, run new power lines into the kitchen, and handled appliance installations like dishwashers and microwaves -- all with a level of precision and care that gave me complete peace of mind. What sets Mark apart is not just his attention to detail or clean, high-quality work, but also his deep understanding of electrical systems and building codes. He doesn't just do the job right -- he does it the right way, ensuring everything is safe, compliant, and built to last. His commitment to doing things by the book never feels like a formality -- it's clearly rooted in genuine professionalism and pride in his work. If you're looking for someone who's reliable, skilled, and takes tremendous pride in what they do, I highly recommend Mark Steinbarg Construction. I'm grateful to have found someone I trust completely with my home's electrical work.

I talked to a couple of electricians before hiring Mark to install my EV charger. The other guys said they’d install the charger and don’t need a permit or contact anyone! While Mark knew what to do to get the job done the right way! He communicated with the city and Southern CA Edison and satisfied all the requirements to install the EV charger. He scheduled the inspection with the city and was there when they came! Five stars work, very respectable and knowledgeable! Very reasonable price!

Mark repaired an outside motion light for me above my garage. He is very knowledgeable, dependable, friendly and most of all his prices are reasonable. I would recommend him.

Mark is excellent. He has done a variety of projects for us from complicated electrical work to leaking water pipes. His knowledge base is amazing. He is thorough in everything he does & cleans up after each work day. His prices are fair. Mark is friendly & professional. We highly recommend him!

Mark did an excellent job on our home project and made some welcome safety suggestions [and work] on other issues that came up while he was working on the project. Great job, on-time and on-budget which we appreciated.
