Sprinkler Quote - is this good?

[Scott J.]

I would like your input on if this is a good quote. I'm in Southern CA, so prices might be higher than other parts of the country.

I had a leaking sprinkler valve in my 90 year old house and the guy came over and basically fixed the leak for free. But our whole valve setup is a mess. There are wires everywhere and four different brands of valves along with corrosion.

He said the sprinklers work good now, but it's just a matter of time before something else happens. He quoted $330 (which includes the valves) to redesign our whole valve system so the wires are cleaned up, most of the PVC is underground (to avoid breaking), and installation of the new valves.

This sounds like a fair estimate to me, but I'm new to this. The four valves by themselves cost $140 at Home Depot.

What do you think?
