Excellent service. I now feel secure knowing that my sump pump will go on if the power goes off. Unfortunately, I didn’t install the battery backup before the March storms. After Global had done several jobs for me in the past, I thought I was finally going to live without water in my basement but Mother Nature had other ideas. Luckily Bob came to my rescue rather quickly after the flooding. Now I KNOW I’ll be water-free. Bob has never tried to pressure me into buying something I don’t need or can’t afford but I wish I had bought the battery years ago when he first told me about it. I won’t make that mistake again. Cost-wise, Bob will break down the requested work into separate jobs and estimate each so I can make a decision if I can afford all of the work or only some of it. I don't think I've ever worked with a service provider who either answers his phone immediately or calls back promptly. Bob has always kept our appointments, except once when another customer had an emergency. He said he was willing to come over later after hours if I needed him that day. We set up another day for my job, as rescheduling was not a problem for me. I really appreciated that he didn't leave me hanging by not showing up or not calling, like a lot of service providers do. Bob cares about his customers and I’m happy to recommend him and his company.
