Lawn Care O'Fallon MO | Lawn Service O'Fallon MO | Irrigation Systems O'Fallon MO

When it comes to your lawn you know that it’s the highlight of your home, the very first sight people will see, and a neat lawn is always attractive. When you’ve got plans for the summer and your grass just isn’t working with you, what can you do? You can continue on the same path and hope it works, or you can call the most trusted name in lawn care and lawn service in and around the O’Fallon area: Lawn Authority. When it's the health of your lawn, you don’t want to take any chances. Choose the business that’s going to be there for you. Whether you’re looking at our lawn services or a custom irrigation system, Lawn Authority has been working with local customers since 1981, keeping our close knit company the way we think businesses should be: honest. Customer satisfaction has never been an issue with us, and our work speaks for itself; if the work was bad would the owner have kept mowing lawns from he was twelve? Of course not, because we’ve proven that we not only care about our work and our customers, we care about O’Fallon as well. If you’re looking for a good lawn fertilization service that gives back to the community then you’ve found the right people; our fertilizer isn’t something you can just buy at a store, it’s custom ordered from a local vendor. When we said we take care of our customers, we weren’t kidding! Our owner grew up with grass and lawns and the local citizens of this city and always knew he could return the favors this place has done for him, so our prices are the best you’ll find for the best possible service around. We mentioned irrigation systems. Why should you want that when you can simply water your lawn yourself, right? Well if you’re one of those people with a full schedule, watering your lawn can easily – and quickly – fall to the end of your to-do list. A lawn sprinkler system can provide you with the simplicity you need to maintain your schedule while still having an emerald sheen that comes with healthy grass. But we know that there are people who are barely home, and even those that have a hard time getting up and moving the way they used to, so our extensive lawn service package is there to handle all your needs. Whether you don’t have the time, need some assistance or just want a professional to ensure your lawn looks the best around, call us here at Lawn Authority and let us take care of you. Our thirty-four years of experience have proven our ability to keep customers coming back for more. With the big businesses in America treating you as nothing more than another dollar walking, let us bring back that family feeling you used to get from back in the day.
