I can't thank Alfred enough! Our main power breaker decided to crap out on us on a Saturday evening and Alfred was the ONLY electrician we could get a hold of at that time. We were doing basement renovation electrical stuff, so he had us [...continued]

Lindsay O.5 Star Yelp Review

Best electrical company I have ever worked with. Very up front and had great ideas to help with costs. Work was fast and clean. Great team. Had an electrical panel upgrade from 100 amp to 200 amp.

Al at OHM has been a godsend! We called OHM panicking because we had a sump pump problem and not only did he get to us ASAP, he talked my husband through the process so he could understand what was going on. We enjoyed the [...continued]

Onika G.5 Star Yelp Review

After installing new siding on our home, we had an issue where a circuit breaker would constantly trip. This left us with no power to 1.5 of our 3 bedrooms. Within 48hrs, OHM was able to come on-site (free) and produce a quote to troubleshoot the issue. [...continued]

I had an excellent experience with Alfred of Ohm this past weekend. First, he showed up at the appointment time which is first class with contractors these days. He assessed the job quickly and accurately and completed every task within the [...continued]

Wayne H.5 Star Yelp Review

I live in a vintage camper trailer with dated and poorly done wiring. I called after one of my lines stopped working. Alfred quickly diagnosed and repaired the issues, while also providing useful electrical information.

Gabrielle Oglesby5 Star Google Review

Ohm is great! We are purchasing a house and there were some significant electrical problems. Ohm was quick to come to the house, investigate the issue and provide their guidance. We will certainly be using them for any future electrical needs!

Mick C.5 star Yelp Review

I called due to smoke detector going off without any apparent reason. Ohm returned my call promptly, had someone out to our house before the end of the day. [...] I will call Ohm again for any future electrical needs.

Sarah M.5 star Yelp Review

We had Ohm Electrical Contracting add a 50 amp NEMA outlet and a whole-house surge protector to our panel this summer. Start to finish in under 3 hours. Alfred was punctual, courteous and knowledgeable, answering any and all questions happily. Will definitely call them again for any work we need done in future.

Ken C.5 star Yelp Review

I called Ohm and they got the work done in just a couple days. They installed 5 outlets in our basement. Thanks!

Jaimie F.5 star Yelp Review

OHM is a great company to work with. Alfred knows what he is doing and is friendly and gets the job done just as he promises. They are my go-to for all electrical issues and installations for my 3 Seattle businesses as well as my residence.

Jarrid S.5 star Yelp Review

Great experience working with Alfred and his crew to install an outlet for an outdoor sump pump. They fit us in quickly and Alfred spent a good amount of time talking through options with me. Definitely would use again.

Dave O.5 star Yelp review

They've helped with large projects (installing a car charger) and slightly smaller projects (running new outlets to a room from the breaker box) and they were very helpful and knowledgeable the whole way through.

Christopher Y.

Highly recommended ! Alfred was able to trouble shoot and resolve our electrical problem at time of visit. We are happy to have our lights and outlets working again. We will definitely use OHM for future electrical jobs!!


Came out within an hour of calling him on a Saturday afternoon to fix a major problem with our electrical system at our business. Super fast and professional. Clearly explained the issue and fix and made us feel comfortable with the result. We will definitely be using Ohm for any future electric work.

Matt W.

I had a great experience with Alfred Paul. He was communicative, prompt, readily available, and knowledgable. He did homework on my problem in just the few hours between when I called and when he came to my home. Highly recommended.

Deborah J.

Alfred is an amazing, honest, friendly guy who is skilled at his work. His people skills are very high. Good communication. Kind person. I highly recommend Ohm for your electrical needs.

Renee H.

I don't normally put in reviews but after my ordeal trying to find a good electrician and striking out I had to put this in. I had a not so common request where I recently purchased a 150lb corn mill that was stored in my garage [...full review on Reviews page]. Thank you so much Ohm Electrical Contracting! 🙂
