Very personable and patient!

Both technicians that came to our home were great! They were very personable, and very patient. My mother in-law has a hard time with her English, as it is her second language, but they were both very patient with her, and made sure she understood everything that needed to be done. On their customer service alone I would recommend this company. We live in an old 1980's trailer which made it hard to find parts needed to fix our heating system, but they did all the research they could to try and find the parts needed. I am so glad I decided to call Mainstream Electric and will continue to use their services in the future.

Cody was respectful, personable, courteous, answered all our questions we had during his visit, knowledgeable. Cody helped us get in touch of the appropriate people, to finance the work that our home needs. He helped get the work scheduled so that we wont need to wait longer to get the work taken care of.

What Do I Do if I Think My Water Line Has Burst?

If you believe that your water line is broken, immediately shut off the main water to your house. Then you should call Mainstream to send our expert plumbers to diagnose and fix the problem in a timely manner. We value your time and understand that a water line installation is a big deal. When you call, make sure to ask about same-day service so we can help you promptly.

How Much Does Water Main Line Installation Cost?

Mainstream understands that home services like installing a new water main line can be costly. That’s why we provide financing options so you don’t have to sacrifice quality when it comes to your home.

There are a few factors that can affect the pricing of a water line installation.

Type of Material
The type of material you choose for your water pipes will greatly affect the price. PVC is a cheap plastic that will do the job but is not as efficient as other more expensive materials. For example, copper piping is the most expensive material for water pipes, but it’s also the highest quality. Our technicians will offer you personalized solutions based on you and your home's needs.

How accessible your water line is affects the price for installation services. A water line that is difficult to access requires more tools and labor to complete the job, which adds to the price.

Water Line Length
The distance from your home to the city water line is another determining factor in the cost for a water line installation. The farther away it is, the more materials and labor hours will be needed.
