Positive: Professionalism
They have gotten me out of so many predicaments it's not funny. Service is fast and affordable. Would not use anybody else.

Thank you,
I live in Rochester, N.Y., but own a rental property outside Corning. When the pump failed to deliver water.
One phone call dispatched techs to my site where I believed the pump was bad. Soon I was told it was a broken leg of the 220 electric power at the connection with pump 120' deep.
Bottom line ...
I experienced prompt same day service with above average customer service all with a phone call.
This was an extremely positive exchange in a world where too frequently negitive service is common.
Thank you!
Regards,
Dave

The guys from Terwilliger's have been to my house twice now and have fixed two problems with my well and an issue with my sump pump. Now, it's a little weird to use "thrilled" concerning pumps and wells but I have been absolutely thrilled both times. Each time, they came within 24 hours of my phone call and fixed the problems quickly. What is so great is that I live in an older home with original equipment and they have replaced only the faulty parts at a very cost-efficient rate, while providing time estimates on when other parts might need updating with no pressure to replace the whole system
