Mainstream has become very familiar with our house these last few weeks, and I cannot express enough how impressed we have been with their service. Everyone from the start of the phone call to the end of service was amazing! We first reached out because we were wanting to get estimates on getting the electricity fixed in our shop, we were able to have Sam from mainstream come out within a day or so of us calling and luckily Sam found a big issue (likely fire danger) that needed to be fixed ASAP for the safety of our house! Within that same week our shop had been we rewired by Brandon (and his cohort, I’m so sorry I can’t remember his name) and Bobby and the issue was solved and the trench that was dug was literally filled in yesterday 3/29! Then today we had a plumbing issue that was causing a huge headache, multiple trips to several hardware stores to try and find a part to just plug/cap the issue & lo and behold we weren’t going to be able to MacGyver through it anyways. We knew we could call mainstream and have full faith they would save our day! Sam R. was able to assess our issue, give really good advice for later down the road and fix our indoor water park in less than an hour! Hopefully we won’t have to call in mainstream again anytime soon, but we know for a fact, we will call them in a heartbeat for any issue!

So I bought a lemon "Rheem gas electric" tankless water heater about 5 years ago and it's had problems ever since.. the young man "Sam" who came to my house on a Sunday looked at this thing for about 10 minutes and came to the conclusion that it was installed wrong and they damaged the mother board to it. I have to buy a new water heater but even though it cost me.. the experience and friendliness was worth it

An electrician came out within 24 hours of my call, even on Sunday afternoon! He fixed the problem promptly. We've had other work done by them and they always produce professional, high quality work.

Sam Rodriguez, plumber with Mainstream was amazing when I had damage from a leaking water heater. He helped me through the process of working with another water damage contractor for repairs and get my water tank up to code and repaired. I can't thank Sam enough and the Mainstream team for helping me out with this stressful situation. You guys are the best!!!

If I had only asked a general contractor friend of mine for a referral rather than Angi, I would have saved myself hundreds of dollars. I didn’t realize their employees worked on commission. They charge $ 80.00 to come out to give a bid. They billed me $885.88 for one hours work. After I returned their survey complaining about their obscene prices they issued a $188.00 credit. I will never have Mainstream do work for me again and I will certainly never recommend them to anyone.

Mainstream installed an undermount sink to replace one that another contractor broke. Mainstream did a great job. Their ability to do the job quickly allowed me to sell my house on time.

The carpenter and his helper did a fine job on the drywall repair and shower door installation. It all looks great, just like in a high-end new house. Recommended!

They were great. Everything was done on time. The job required an electrican to arrive which he did. So the plummer and electrican worked together so the job was completed in one day.

This company and people have been a joy to work with. They have been very thorough with communication and following through with the steps. Questions were answered promptly and professionally.
