How much do automatic sprinklers cost?

Answer 1

For a quick and dirty estimate of where you might expect bids from professional sprinkler contractors to come in, use a range of $0.50 to $1.25 per square foot of area to be watered. Small properties and properties with complicated layouts will tend to be at the higher end of that range. Where you live and what type of equipment you select will also impact the range of bids.

If you are installing the system yourself, you should be able to buy equivalent materials at a home improvement store for about 15-20% more than a contractor will pay at a contractor supply store; however, you will need to factor in rental of trenchers and whether you can install the backflow prevention device, so you should figure your total cost of installing an equivalent system yourself will be 40-50% of a professional sprinkler contractor bid.

For more specific information you can search for "Sprinkler System Designer" on the internet and find applications that will let you put in the parameters of your yard and will output a parts list with prices.
