Recommended Customer Reviews

We have called on Dean twice now and both times he has fixed our problem and given us options for future fixes. Very nice and honest.

As a real Estate professional, we always strive to refer to our clients only the best of the best - professional tradespeople that we can put our name to who know how to serve, who do a great job, and who are honest, upfront, and timely. Dean at Interwest exhibits all of these qualities - hes a great guy and someone that we have referred time and time again and our clients love him. He's by far the best electrician we know, and our first choice when it comes to our own electrical needs as well as any of our clients.

I had a bid from another company to relocate two can lights in my kitchen ceiling. That other company wanted $434 EACH to do the job, and would have re-used all of the old parts. Dean quoted me a price of $290 for BOTH, including NEW cans which re-used the old trim to match the other lamps which were not affected. He also gave me a very fair price for some other work. So I decided to let him do the job.
Only a few days later he came by with his worker ELVIS who did everything quick and clean, and with good humor to boot. There were a few other projects I needed done, and Elvis was happy to crawl up into my 150°F attic to run some wiring for a new microwave oven and some ceiling fans. None of this extra work was on the original job ticket, but he did it with the same quality and humor he started with, even going a bit into overtime. Everything works as it should and my house doesn't have a single hole or scratch that I didn't expect.
When all was finished, I ended up paying less for all of the work than that other company wanted for only moving two lamps.
ELVIS HAS LEFT THE BUILDING!

My son found this company on yelp and he contacted them and made the appt.they showed up on time, Elvis and His assistant showed up which I thought just to write an estimate about the type of work and return again on another day . But they appear ready to tackle the job ""Ora mismo""! And waited for my instruction and they figured out right away what needed to be done. To make it short, they got the job done professional and made my wife happy (especially the attic fan) and this got me out of the hot sit! The price was fair and reasonable. I have more work for them later. You guys should be on Angie's list .

Returned calls promptly. Showed up on time and finished quickly. Quote was reasonable and work they did on light switches and ceiling fan outlets all great. All around a very good experience.

I have utilized Dean at interwest 3 times and have been very happy with his service on each occasion. He has always been very pleasant and professional. In the past, he has taken the time to help me troubleshoot problems on the phone and has helped me by imparted his knowledge and experience with me. His prices are reasonable and I am sure that he has done a quality job.
Today, he was able to skillfully find an electric short in one of our outlets that continued to trip my circuit breaker. On prior occasions, he has placed new outlets and installed new lights in our house. I have been very happy with his work and his professionalism.

This company was great. I had an outdoor motion detecting floodlight that needed to be replaced. They arrived on time, and took care of it in about 20 minutes. I am very satisfied with the service and I would recommend them to anyone.

I have had two complicated electrical problems in a house that was built 85 years ago. Dean fixed both of these problems very quickly and at a very reasonable price. I give him my highest recommendation and will certainly call him for any future needs.

I've used Interwest for two projects, and they're deserving of repeat business. They're not the cheapest in town, but they are reasonably priced. Besides, do you really want to skimp when it comes to the electrical in your home?
The owner, Dean, has come to my house to personally bid each of my projects. The second project I had started on my own and I needed their help with one last fixture. Dean thought of another, less intrusive way to achieve my goal, and it involved only a $25 part that I could install myself. Even though it meant losing a sale, Dean did the right thing for the customer!
Do yourself a favor and call Interwest Electric.

First, I want to say THANK YOU to the owner, Dean Mastrovic and his crew Miguel Hernandez, Elvis and Jose for doing the electrical work at my property. You do get what you pay for and more from INTERWEST. Miguel, Elvis and Jose are very well versed in their professional. Interwest Electric is doing a project at my residence as I write this review. Dean's crew takes pride in the work they do. You could almost say that the crew is very passionate in what they do.They cleanup after there job is completed, and check every item done that needed to be repaired. Always on time at the jobsite and the crew gets started on the task assigned to them. If Miguel, Jose or Elvis finds a problem, they let Dean know of the electrical problem and the crew works on the electrical problem until it is corrected. I have decided to keep Interwest Electric on my speed dial in case of an electrical discrepancy at my place of residence. There is NO other company I trust to do my residential work except INTERWEST ELECTRIC. My thanks to Dean and a special thanks to Miguel, Jose and Elvis. I tip my glass, raise my hat and applaud the CREW OF INTERWEST ELECTRIC.
