We had a number of quotes from Calgary companies for our lawn sprinklers and one from Dirty Work. Well there quote was about middle of the road for pricing but they gave us a 5 year warranty and a great installation. They are also certified in weather based timers and we are saving tons of water and money now as well. We have had the system for 4 years without one problem. Thank you Christian and the gang at Dirty Work. We recommend you to everyone we know!!!!
