We have used this company twice and both times found them to be dependable, punctual and trustworthy. The first time was a few years ago when we called them to get a second opinion on a very expensive estimate quoted by another (larger) company. Sinjac said we did not need all the work the first company quoted. In fact, a simple repair to an outlet was all we needed. Frank made the repair and only charged us for the service call which saved us thousands of dollars over what the first company quoted. We were so impressed, we recently called them back when we needed help with a light fixture installation. We received the same professionalism and quality workmanship as before. It's a shame that more companies do not have the same level of integrity as Sinjac. The next time we need any electrical, heating or AC work, we'll be sure to call Sinjac again! read more

We live in an older home in Wheat Ridge. I have known for a while that we would need to have our electrical panel replaced. We ended up adding some new circuits and relocated a electric dryer in addition to replacing the original electrical panel. Amanda was great to deal with and her communication was on point. They completed the work in a timely manner and it passed inspection on the first go around (which hasn't been my experience with most Wheat Ridge inspections at my home). The quality of work and job cost were very fair. Would definitely use them again when we need electrical work! read more

My family has been using Sin Jac for years. We have used them for everything from fixing the furnace to installing outlets. Most recently, they did a service panel change in our rental house. I can't speak highly enough about the professionalism they exhibit. They arrive on time and get the job done. I honestly wonder if the other reviews on here were for the correct company, because I've never had a bad experience. Sometimes I hesitate to refer my friends to businesses I use because doing so puts my credibility on the line, sin jac is the exception. Happy to refer them. read more

We were referred to SinJac from a friend. We had gutted out our kitchen and had run into some problems with our wiring and also wanted to add new lighting along with several GFI outlets. We were on a stand still as we no longer had power. We called Sin Jac and they were able to come check it out fairly quickly. They gave us an estimate we liked and they completed the work a couple days right after. Frank is very detailed and clean, he went above and beyond to make sure we were satisfied with all the work completed. We look forward to using their services in the future. read more

We have been struggling with electrical issues in our basement since we bought our home 6 years ago. We finally got connected with Sin Jac Electric and could not be happier.

He also corrected a faulty 3-way switch while he was here. Highly skilled and very professional company. They are now my go to for all of my electrical needs in the future. read more

I called Dr Fix it first and they tried to tell me I needed a new electrical panel (over $2000). Matt and Matt from Sin Jac came by hours after and found that nothing was wrong with my panel. They found the problem to be only a light switch connection. they were in and out in less than an hour, actually found the problem, and saved me a ton of money. Hard to find honest contractors here in Denver. I highly recommend this one! read more
