  • 5/5 stars Electrical and Wiring Issues Verified Review

    Kevin shows up on time. He recommends the best solution for my problem while it also costs me less money. I definitely would recommend Kevin.

  • 5/5 stars Electrical and Wiring Issues Verified Review

    Professional accommodating personal and cost effective. Kevin installed a sub panel and 240v to accommodate a charging station for our new leaf. He was heads and shoulders above a year of the other electrians we spoke to. Would definitely recommend him and would hire again!

  • 5/5 stars Lighting Installation Verified Review

    Kevin installed a chandelier over our dining room table, using the power and switch from an existing outlet that was set up for lamps.

    While this wasn't the most technically difficult job, we are happy with how the job turned out, and he even patched and mudded the drywall holes he had to cut to run the cable to the ceiling. We'd definitely use him again.

  • 5/5 stars Fixtures Verified Review

    Kevin was prompt, professional and tidy. He tested my kitchen light to verify the problem and was able to fix the fixture's ballast. While I explained other projects I would like help with, Kevin walked me through what I needed and the cost. Once I am ready for these projects, I will definitely be calling Kevin.

  • 5/5 stars Fixtures Verified Review

    Kevin was professional from start to finish. His 20+ years of experience was evident right away. His quote for our complex job was very thoughtful, thorough and reasonable. His service level when he arrived to do the work was outstanding. He even gave us tips on how to save money (at expense of his services) because he's truly looking out for the customer. Highly recommend A++++

  • 5/5 stars Switch and Outlet Installation Verified Review

    Timely, friendly, knowledgable and reasonable!

  • 5/5 stars Electrical and Wiring Issues Verified Review

    Kevin came on time, diagnosed the problem, saved us money and was pleasant. What we thought was a circuit breaker was a bad switch. He did more than I asked him to do. Would definitely call him again. Thanks Kevin.

  • 5/5 stars Switch and Outlet Installation Verified Review

    Kevn did great work. While working on my repair found an old fixture that was not up to code and a very dangerous fire hazard. Fixed that as well as all of my odd electrical jobs I requested. A+ service. I will call him again in the future

    Mr. Kevin Jensen from KJ's Custom Electric was hired to fix the electrical problem with my microwave oven. He was courteous and on time. His quote was the most reasonable from the four I had received. He was able to find the problem and fix it immediately. I was very impressed and hope to hire him back for several future projects.

  • 5/5 stars Electrical and Wiring Issues Verified Review

    I had a mystery problem that no one had been able to trace. Kevin happily solved it in record time and said he liked a good challenge. Then he charged me only his minimum fee. A terrific experience and a highly skilled electrician.

Question and answer

Q. What education and/or training do you have that relates to your work?

A. Every electrician MUST have a license to be a certified electrician. (MAKE SURE YOU CHECK THIS). Every two years the electrician must take a minimum of 32 hours of continuing education. As an electrical contractor I also maintain my membership as a journeyman electrician with IBEW 302 and all classes are free and members are encouraged to take as many different classes as possible.

Q. Do you have a standard pricing system for your service? If so, please share the details here.

A. The cost of a job will vary on the complexity and accessibility. I bid my jobs at $75 per hour. My price has not changed in over 15 years. Remember you get what you pay for. Don't pay for what you don't get.

Q. How did you get started doing this type of work?

A. I was brought up in construction My father was a building contractor my Uncle was a building inspector in a local east bay city. My second uncle was an engineer for Kaiser Industries working out of Oakland, and, actually began his career at the Kaiser shipyards here in Richmond! I had the best of mentors. I started taking electronic classes in eighth grade in high school and thru college. I truly love my work as every job is a new and challenging experience. I strive for perfection.

Q. What types of customers have you worked with?

A. Most of my work has included collaboration withe three other General contractors. we have worked together for 25 or more years doing a variety of projects. One of them, as a private contractor, does many remodel jobs on UC Berkeley campus, as well as for residential customers; another is a remodel expert on local upper class homes, and the other specializes in kitchen and bath remodels. These colleagues are my priority, however, I have found Thumbtack helps me with periodic slack time that I can devote to individual work. Other than Thumbtack and an occasional ad on craigslist I have never had to advertise as all my jobs come from happy, satisfied client referrals.

Q. Describe a recent project you are fond of. How long did it take?

A. I have a ongoing contract with UC Berkeley and have the job of replacing all of the old outdated lights in many of the campus parking structures. I recommended that new LED flood lights will give as much or more lighting (lumens) than the outdated fluorescent lighting at a much lower cost. A LED flood uses 30 watts compared to 160 watt tube fixture. I received many compliments from staff and students on these jobs.

Q. What advice would you give a customer looking to hire a provider in your area of work?

A. If possible do your homework, check that the contractor is licensed and insured. Talk to the contractor on the phone or in person, look for any red flags. Try to verify work experience and make sure the job you want is one the contractor is competent to complete. Get more than one bid, three is a good minimum. Look at the work vehicle. Is it properly set up, are the tools sufficient for the work you need done? As questions.

Q. What questions should customers think through before talking to professionals about their project?

A. I have been in business as a licensed insured contractor for over 33 years, I have a very good reputation and guarantee all my work. I have passed my background checks, and have never had a legal dispute in over 30 years. My work history includes service positions for all of Wells Fargo Banks from San Jose to Concord area. However working for a large corporation became much to demanding because of the many times I had to stop what I was doing and travel to fix their problems immediately, ignoring my private business customers. I much prefer being my own boss, depending on my own skills, knowledge and abilities and the quality of my work and satisfied customers to ensure my success.
