About Guerriero Landscaping
Decades of experience. One simple promise: treat every yard like our own.
Les Guerriero
Guerriero Landscaping is an owner-operated company serving both residential and commercial properties for over 15 years across Madison, Chatham, Florham Park, Whippany, and surrounding areas. You call Les, you get Les, on every job, every time.
We provide full seasonal maintenance and landscaping from spring through fall, and into winter with snow plowing and salting. Les is a NJ Certified Pesticide Applicator (#91580B) specializing in lawn fertilization, weed, insect, and disease control. We take an organic-first approach: everything we apply at your property is what we use on our own.
The Guerriero Difference
Owner-Operated
Les is on every job. No subcontractors, no rotating crews. You work directly with the person who built this business over 15 years ago.
NJ Certified Applicator
Licensed Pesticide Applicator (#91580B) for lawn fertilization, weed, insect, and disease control. Not just experience, credentials to back it up.
Organic-First Approach
We always start with organic-based products and only escalate when truly necessary. As dog owners, we care about what goes on a lawn.
Full Season Coverage
Spring through fall maintenance and landscaping, into winter with snow plowing and salting. One company, one relationship, year-round.
Soil-Driven Programs
We don't just treat what's on top. Soil testing, pH correction, aeration, and amendments to build a lawn from the ground up.
Direct Line to Les
No call centers, no ticket systems. You have Les's number. If something needs attention, you call him and it gets handled.
Bailey Approved
Organic-first lawn care
Meet Bailey
Bailey is Les's golden retriever. He often tags along on jobs and has gotten to know a lot of the clients over the years. Having a dog around is part of why we went organic-first in the first place. You start thinking differently about what goes on a lawn when your own dog is lying in it.
That's all Bailey Approved means. We use the same products on our customers' properties that we use on our own. No more to it than that.
Organic-First
We always start with organics, escalate only when needed
