Recommended Customer Reviews
Ann P.Great job today by Jose and Juan. I am a first time customer and am very pleased with the prompt response by Dean, followed by quick scheduling of the work. Juan and Jose arrived promptly and completed the work, including clean up in less than the anticipated amount of time! And that was with a challenging wall to penetrate. Quality work, very polite and professional. Will use again!
Interwest recently completed the relocation of our main breaker box to a sub panel inside the garage. The work was completed in one day by a very professional crew of trained professional electricians. We highly recommend this company for your simplest to your most complex electrical needs. Dean is very customer service oriented. 5 stars from us!
Ady A.Awesome service!
I have call them and and after 2 minutes Dean Mastrovic gave me a call back. I asked him about some concern that I had. He came to the house and confirmed that everything seems fine, without even charging anything for this.
Will definitely use Dean again for every issue I have.
Couldn't be happier with our electric work on the house by Interwest Electric. Frankie & Luis did an amazing job figuring out the mess of our wiring in our master bedroom that created problems including our fridge to be without power. They were considerate in placing a sheet over the bed and vacuumed up the mess when they left. I couldn't even tell we had work done except for the fact we now have our fan & light on a switch and the outlets to the rest of the house are working. Will be using them again in the future. Appropriate pricing and efficient work. Made a headache of a problem less stressful!
Called the top three electricians on yelp east county.
First one didn't call back for two days.
Second one spent 20 minutes on the phone laying the groundwork for a huge up sell.
Jose at Interwest is awesome. Fixed the problem and fixed two other minor issues.
Price was great. Service A+ This is the guy to call!
Natalie B.Dean and his wonderful team at Interwest Electric did an amazing job repairing and finishing electrical work at my home after the original contractor quit. Everyone was prompt, professional, and friendly. Thank you so much for helping me complete the project. I appreciate it!!
Katie S.We had Interwest Electric install three ceiling fans in our home. They had to do all of the electrical to the existing switches, which were not connected to anything. They put in dimmer switches and the ceiling fans, which have worked wonderfully. They were clean and didn't leave any mess behind. Our only ""complaint"" is the patchwork from where they had to put holes in the walls and ceilings (the size of a cantaloupe) weren't textured the same as the surrounding areas. So my husband had to sand them down and make them look nice before painting them. They also accidentally drilled a hole through our medicine cabinet, but immediately replaced it!
I've been using Interwest for electrical work for going on 12 years for any type of electrical work I've needed at my homes over the years. Initially they saved me when the ceiling heat in a condo I was selling did not work and was causing concern with buyers. Dean suggested electric wall heaters that were an excellent and cost effective solution. Most recently, I have engaged them to do some work on a new home I just purchased. Dean came out on a weekend to take a look at what we needed and followed up with a quote within a few days. Dean and his firm are top notch. The service is excellent, the staff are professional and courteous. Fair prices as well. I highly recommend them to anyone.
Frankie did a great job. Confident in their work and knowledge. Fair price and got started as soon as they could. Very honest and kind.
My electric range wasn't working, and after spending a couple hundred with appliance repair, they ultimately decided it was a home electrical issue which they couldn't deal with. So I called Interwest on the weekend and got the messaging service because the Interwest guys take weekends off. (Good for them!) Dean from Interwest still called me like 5 minutes later, and we arranged a Monday appointment. He was there on time, and was like a bloodhound tearing into my breaker box. Diagnosed the problem within 5 minutes, went and got the necessary part, replaced it, and was gone! Botta Bing - Botta Boom!
