Sunday lawn care reviews near Issaquah, WA
Homeowner
I tried Sunday this past year and I’m so impressed. I followed the Sunday schedule and I’ve never had a more plush, thick green lawn through the summer, fall and now winter. I’m one of those neighbors that wants the best looking yard on the block (even with two dogs) so have tried everything. I’m now sold on Sunday!

Looking like a golf course in my yard!
Sunday has my lawn looking green, healthy and ready for enjoyment for the family, kids, dog and neighbors. The applications are easy to do, and I've been happy with the results. It gets VERY dry for weeks and weeks during the summer in Seattle, and their soil analysis did a good job of giving me the right kind of ingredients to make sure that our soil and grass retain water and stay as healthy as possible!
