What Our Customers Say

We called and he came within a couple of hours, he looked the job over, gave us a price and changed out the filters on our soft water system. He covered his shoes when he came in and was very pleasant. I highly recommend them. We joined their Care Club and feel that it's a good deal. We will call them again when needed.

Zac came out to perform maintenance on our HVAC. He was professional, efficient and thorough. Highly recommend ZAC and Mainstream Electric. Good Job today!!!

Very prompt, took my concerns seriously and put my mind at ease. Very friendly and on time.

Zach is very friendly and informed me of all he found and gave good sound advice.

I appreciate Adams help and professionalism regarding my repair and understanding my options. 1st class technician.

First of all thank you for the prompt professionalism of your staff, I had called the installer company and they canceled, postponed twice so I said forget it and called you. Gabe Franklin arrived quickly and did a thorough job and wa-la I have heat again! He wasn't rushed. I thank you for hiring him. Can I request him on all future service calls? Lori Forges

The technicians were so professional. They explained what the issue was and the different ways to fix it. So quick, kind and they cleaned up after themselves. We were very impressed!

Technician diagnosed the problem and suggested a new water heater for us (one that would do what we need as was less effective. Installed did a great job. Everyone was on time, courteous, friendly and professional. Our overall experience was very good.

5 Stars!!! One of the best experiences I’ve ever had with a plumbing service. Ricky was so great to work with!! Thank you Mainstream.

The night of 3/16/26 I was doing dishes and my kitchen drain plugged and I got my plunger and began to work on the drain and of course I didn't unplug it so I booked an appointment to have a tech come out to get rid of the plug. First thing I have a guy call me and confirm I needed help and sent a Tech out with in 30 mins on 3/17/26 and he was the nicest guy took 20 mins and got my drain working again. Thank you Mainstream Electric & Plumbing you all the best. Thank you Billie Rae Kidd

Super friendly and fast service, reasonably priced

Very professional and tidy

Pierce was very professional and serviced our main line plumbing drain with expertise. Thank you Mainstream.

Pierce did a great job, explained everything clearly and it was easy to understand

We called because we were having to plunge our toilet frequently and assumed it was a drainage/clogged problem. After examining the plumbing under our older home (1946) many deficiencies were discovered that contributed to the toilet flushing issue. Many different repairs over many years were not done correctly and it turned out the best recourse was to remove and replace everything and also to install a new propane tankless water heater. It was a 3-day job but handled expertly; with cordial, considerate and knowledgeable technicians, both Robert and Ryan. I could not be more pleased. I highly recommend Mainstream. Additional comments: Although the initial work done in 2022 was satisfactory there were some follow-up issues that were not handled well and communication was nonexistent. We gave up on getting any satisfaction for our issues. About a month ago our tankless hot water heater needed attention so we called Mainstream again. Steve S came out and answered all our questions and met the immediate needs. We were impressed and I am pleased with the work so far. Just today March 16, 2026, Pierce came out for a drainage inspection included with the care package we purchased. He is the “Duke of Drains” with his knowledge of all things under the sink which he gladly shared with me. My bathroom sink drained slowly and he fixed that with duke like expertise. After being frustrated and annoyed with Mainstream for the past 4 years, our faith in the company has been restored and I gladly give another 5-star score. This in large part to Steve and Pierce. Thanks guys!

Ricky was very pleasant and professional would recommend him to do more projects

Pierce Fleming was amazing. He explained our plumbing problem and why it happened. Then gave suggestions on how to prevent our pipe from backing up in the garage in the future. Super pleasant to talk to.

You guys are more than professional. Can't thank you enough. Good job.

Courteous, thoughtful and respectful. Great experience and can't say enough about Josh. First time with Mainstream and it was the perfect choice.

I think everyone gets nervous when your pipes aren’t working. My parents are 80, my mother has Stage 4 terminal Cancer and they are both in poor health, physical and financial. These guys from Mainstream were literally the most amazing group of guys I have ever met. They were so considerate of my mother’s condition and our family as a whole. They tried extra hard to get things done easy and on the lower price level over and over as well as working hard for us on every level! Between the first young man that came over, I think his name was Jacob, to the manager, Matt, we felt heard and included every step of the way. This is the type of local company that looks out for community, they need and DESERVE our support! There is no way we could ever truly thank the folks there for all they did but hopefully they will get the love and support from Spokane and surrounding communities. They aren’t just a local company, they are a friend!
