"Glacier Irrigation went above and beyond to install a new 11 head 2 zone irrigation system with a Rachio timer. This was a new instal that required piping ran in the house to the main line. Sam, the owner, used the best available equipment to instal the lines outside so they did not tear up the grass like all other installers would do. He uses high efficient sprinkler heads to get proper coverage without eating into the monthly water bill. Sam has an excellent plumber, Liberty, who he uses to complete any of the plumbing that needs to be done from the house to outside. The best part of Glacier irrigation is the communication you will receive from Sam. So many companies don't answer their calls, but he is responsive and quick to give an appraisal. I will continue to recommend Glacier irrigation to anyone looking for their lawn to come back to life."

"David and his son, David (Great Lawns Landscaping) upgraded a very old distribution box of our irrigation system, which was installed personally by a previous owner, so that it would operate like a brand new system. They took on a job that most irrigation contractors would only shake their heads. Not only did they intelligently determine how to make a tricky repair, but they did it right away at a very reasonable cost. They will be my first choice for irrigation issues in the future. I highly recommend them."

Lawn Irrigation FAQs, answered by experts

Each season’s climate influences approaches needed for effective suppression.

If it’s been a few weeks and you haven’t seen anything pop up, double-check your seed packet and make sure you didn’t miss any steps. Did they need cold stratification (putting seeds in the freezer and then transferring to water before planting)? Do they have an exceptionally long germination period? 

 If you’ve followed all of the directions closely, you may just have had a bad batch of seeds. (Sadly, it happens.)

Overseeding typically involves spreading grass seed either manually or with a machine that sprays the grass seed out and onto the soil. With overseeding, the grass seeds sit on the soil, and some may fall deeper into the soil if you aerated beforehand. With power seeding, a machine cuts narrow rows into the soil and pushes the grass seeds directly into the soil.

Yes, it's common for lawns to look bare after dethatching. Dethatching brings soil to the surface to create a "bald" look on your lawn. While you may choose to patch or reseed your lawn if bare patches seem excessive, it's normal for a lawn to look bare after dethatching. With the layer of debris that was blocking water, nutrients, and air from reaching your grass now gone, your lawn is likely to grow better than ever.

Hiring a professional lawn care service is generally worth the cost, especially if you have limited free time. Lawn care professionals can ensure your lawn receives the vital nutrients it needs to grow and thrive, guaranteeing a healthy, beautiful, and well-maintained yard with professional-looking results. While some homeowners enjoy doing the work themselves, hiring a company frees up your schedule. The decision also depends on your budget and whether you already own the necessary lawn equipment, as doing the maintenance yourself can reduce monthly costs. Additionally, many lawn care companies offer other services like snow and leaf removal to keep your property in top shape year-round.
