Lawn Master is a premium lawn installation and renovation specialist, not a general lawn care company. Our core services are new lawn installation from seed, lawn renovation, and lawn restoration. We use seeders, professional-grade equipment, and custom seed blends to deliver results that most companies on Long Island simply can’t match. Every application is handled by NYS-licensed pesticide professionals.
Yes new lawn installation is one of our specialties. We work on new construction, post-renovation properties, and any bare or cleared ground. We use seeding equipment that delivers true seed-to-soil contact and custom cool-season seed blends for Long Island’s climate. The result is a sod-quality lawn from seed at a fraction of the cost of sod.
Suffolk County Local Law 41-2007 prohibits applying lawn fertilizer between November 1 and April 1, no exceptions. Violators, whether homeowners or professionals, face fines of $1,000 per violation. This is why timing matters so much. We build every program around this window, making sure your most impactful applications especially that critical early September fall feeding happen before the cutoff, not after it. Getting the schedule right is the difference between a lawn that recovers well and one that limps into next spring.
Technically yes, but it’s not ideal. Cool-season grasses which, is what most Suffolk County lawns are made of, absorb fertilizer best when soil temperatures are between 55°F and 70°F. By October, soil temps are dropping fast, and your grass’s ability to take up nutrients drops with them. Early September is the sweet spot for fall fertilization. That’s when the grass is actively recovering from summer stress and can actually use what you’re putting down. Late October applications often end up benefiting weeds more than turf.
Yes and this is non-negotiable. Any company applying pesticides for hire in New York must be registered with the NYS Department of Environmental Conservation and employ at least one certified commercial pesticide applicator. Getting that certification requires passing two state exams a Core exam covering safety and environmental law, plus a category-specific technical exam. It’s not a rubber stamp. An unlicensed person applying pesticides on your property is violating state law, and if something goes wrong, you’re not protected. Always ask to see a company’s DEC registration before signing anything.
Because one application can’t do what a sequenced program does and the biology of your lawn doesn’t work that way. Pre-emergent crabgrass control has to go down before soil temperatures hit 55°F in spring. Fall fertilization needs to happen in early September. Aeration and overseeding work best when timed to the grass’s natural growth cycle. Each step builds on the last. A single treatment in April might make your lawn look better for a few weeks. A full program changes what your lawn is capable of over the entire season and into the next one.
