Professional, friendly, efficient and courteous.

Had my water system upgraded, gas lines installed, additional electrical service, furnace and A/C systems replaced, and some plumbing corrections. I had just moved into the house and found a one-stop-shop for all of the essential home systems to be updated and repaired/replaced. They follow up, show up on time, and even call after hours to ensure good customer service. Robert, Zach, Megan, Shane, Kyle, and a few whose names I didn’t catch. All have been a pleasure to have work in my home.

Same-day service!

Able to obtain same day service to troubleshoot a hot water issue. Technicians showed up promptly and wore masks, gloves and foot covers. Thoroughly explained three options for resolution in a professional, no pressure manner. I highly recommend this company.

Above & Beyond

Technician Steve, was very thorough in his investigation. Went above what I asked for, we had a black water flood and I was just asking to have the toilet and sink reinstalled. He put his camera through my sewer system to make sure that we were not going to have future issues. He made sure that I was able to see what he saw. It was educational to say the least and he was great at explaining what was in there. Feel very safe using his services and do not feel that he is taking advantage in any way. Highly recommend Steve!!

Very Professional

It was really shocking the amount of damage our pipes had and mr Johnson helped to explain what the issue was... He worked within our budget and created a couple of quotes with positive solutions. We went with the one we felt was necessary and he worked quickly getting that issue resolved. Very professional and knowledgeable.

Signs your Water Line May Need Expert Attention

Even when your boiler is still heating your home, there are common warning signs Mainstream Electric, Heating, Cooling, & Plumbing knows to look for. If you notice any of the following, a problem with your boiler may be present, and it's time to call the professionals at Mainstream Electric, Heating, Cooling, & Plumbing for a broken boiler repair:

Murky or Discolored Water

If you are noticing murky or discolored water, call Mainstream straight away. This can be a major health hazard as discolored water usually means your pipes are corroded with rust. Or, if the water is murky, a pipe most likely has a crack that is allowing dirt to enter. No one wants unclean water, and it’s best to allow the professionals to handle this job for you.

Low Water Pressure

Are you experiencing lower water pressure? While this does not always mean that your water line needs to be repaired, low water pressure can indicate a major issue if the problem is showing up in multiple fixtures. In these cases, it’s better to be safe than sorry and schedule a water line inspection.

Pooling Water

Pooling water or soggy spots in parts of your lawn can be a sign that your water pipe has cracked. If this is happening, there is a good chance that the crack has been there for a while and may cause extensive damage.

Spikes in Water Bills

Higher-than-average water bills may be an indirect sign that your water line isn’t functioning properly. Whether it’s your water line or another part of your plumbing that is the cause, Mainstream can help investigate the problem and find a fix in no time.
