Liquid Aeration in Johnstown

The summer can take a toll on your lawn. From foot traffic to high heat to mowing and watering, your turf might begin to get worn down as the year progresses—your soil gets compacted and the turf becomes lackluster. We offer liquid aeration that can help perk up your lawn from the inside out. As a family-owned business with over 40 years of experience providing aeration services, we’ll help you get the lush, thriving grass you deserve.

Strengthen Your Lawn’s Foundation

When you treat your turf to liquid aeration in the fall, you’ll be fortifying your turf for the winter and cultivating beautiful grass for the spring. Liquid aeration allows important nutrients, water, and air to penetrate down to your grass’ roots, strengthening your grass and making it lush and vibrant, providing a number of benefits, including:

  • Stronger roots
  • No sprinkler damage or heavy equipment
  • A better alternative to core aeration 
  • No heavy equipment
  • And more!
