Very pleased with One Nation. My 15gallon water heater in the crawlspace could no way handle my needs. Gerardo was responsive, knowledge, helpful and patient especially on which tankless for my needs plus some. Work was clean, effient and $ met value and he even removed my old 15gallon water heater! He caught some maintenance pieces that I was unaware of and remmended reasonable options for concerns I had (like descaler for the tankless). He brought an extra hand and were SO professional with my 2 other projects going on (one project was a little longer, one was earlier and they call converged). OneNation showed me all of their work, let me know what maintenance and when and how streamlined they made all the repiping. I would definitely recommend OneNation and will use for future projects. I'll upload pics once mt house settles down.

We wanted to thank Gerardo for fixing a corroded pipe on our water heater. We are selling our house and the issue was presented via the inspection report. As chaotic that can be Gerardo was very communicative and prompt throughout this job. Thank you very much!

FAQs

  • What is your typical process for working with a new customer?

    As the homeowner you are the boss. The technician will provide you with various options but at the end you call the shot.

  • Describe a recent project you are fond of. How long did it take?

    A roofing company replacing an old beat down roof needed One Nation to remove and reinstall a 3yr old swampcooler. We did just that and the new positioning looks spectacular!

  • What advice would you give a customer looking to hire a provider in your area of work?

    It's simple licensing, honesty and quality. A company that will go the extra mile for your needs and treat your home better then their's. In other words a company that prides in providing 100% satisfaction to their customers.
