"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

There are a few ways to fix your lawn on a budget, including:

  • Identify the lawn care problem and learn how to seed, fertilize, and aerate your lawn. 

  • Reseed old, damaged lawn with new grass that fares better in your environment. 

  • Remove grass from your yard so you no longer need to worry about lawn care costs.

Yes, some grass will germinate in two weeks or less but it will take several weeks more before it is established enough to walk (or nap) on. To grow grass quickly, follow the tried-and-true-steps carefully, starting with choosing a cool- or warm-season grass seed that flourishes in your home’s climate.

In most municipalities, lawn care and mowing companies require at least a business license to operate legally. However, requirements can vary by location, and some areas mandate that landscaping companies be licensed, insured, and bonded, or even hold a general contractor license. Before hiring any lawn service, confirm they are fully insured. This protects you from liability for injuries on your property and also protects the company's employees. You can use Angi's state license lookup tool to verify a company's licensing status in your area.

Yes, after the lawn is overseeded post-aeration, most of the seed germinates in the aeration holes. This leaves the soil undisturbed while lush and healthy grass will grow in the holes' place. The point of this is to create extra turf density in areas that really need it, such as a large patch of dead grass where a shed used to be.

Choosing between sod and seed depends on your budget, timeline, and maintenance preferences.

Sod:

  • Pros: Provides an instant, lush lawn and immediate curb appeal. It's more resistant to weeds and erosion, can be installed any time during the growing season, and offers a consistent appearance.

  • Cons: Has a higher upfront cost, typically $0.90 to $1.80 more per square foot than seed. It offers fewer grass varieties and must be installed immediately upon delivery.

Seed:

  • Pros: Less expensive upfront, making it a budget-friendly option. It offers a wider variety of grass types and is easier for a DIY installation.

  • Cons: Takes much longer to establish, potentially up to two years for a full lawn. It requires more maintenance, including regular weed control, and is more difficult to cultivate.

Ultimately, if you want a beautiful lawn quickly and have a larger budget, sod is an excellent choice. If you are patient, want to save money, and prefer a wider selection of grass types, seeding may be the better option.
