So here's how it went:
I sent a message to Domestic Landscape through Yelp on Wednesday saying I needed a gashed water line repaired. He gave me a quote which was literally half what the competition was charging. He said he could come by on Friday after his 9am appointment.
So, 9am sharp on Friday there's a knock on the door. Can't be the sprinkler repair guy, he had a 9am appointment. Yup, it's him. Not to start the job, but to let me know it's already finished. And I was charged exactly what the estimate said it would be. He even walked me through properly setting my watering timer.
No nonsense, great service. I'm a customer for life.
