Nutri-Lawn aerated my lawn and put in new grass seed in March of 2011. Customer service is good, and they are quite efficient at what they do. I signed up for this service after a polite young gentleman knocked on my door and asked if I was interested. My husband was quite pleased with the results, and we did have lush green grass for the spring/summer of 2011. Beats the hassle of my husband having to install fresh grass himself.
