LAWN CARE — Warren & Hunterdon Counties, NJ
Cousins Lawn Maintenance has delivered reliable, professional lawn care across Warren and Hunterdon Counties since 2012. Our residential and commercial maintenance programs cover weekly mowing at the correct height for your grass variety, trimming, edging along walkways and driveways, and debris removal — every visit, on schedule, no excuses.
We also provide sod installation, overseeding and repair, mulching, and tree and shrub care for clients who want a single trusted contractor handling the full picture of their outdoor property.
EXCAVATION & GRADING — NJ & PA
Most lawn companies don't own an excavator. Cousins Lawn does — along with backhoes, bulldozers, loaders, skid steers, and mini-excavators that allow us to take on excavation work that other contractors have to turn away or subcontract.
We handle yard grading and sloping, yard leveling for outdoor additions, well pipe digging, sewer excavation, and site preparation for construction projects of any scale across Warren County, Hunterdon County, and Northampton County PA. If your property needs to be moved, shaped, or prepared — we have the equipment and the crew to do it.
COMMERCIAL SNOW REMOVAL — Warren County NJ & Northampton County PA
Cousins Lawn Maintenance provides seasonal commercial snow removal contracts for office parks, retail centers, churches, schools, restaurants, and residential communities throughout Warren County, NJ and Northampton County, PA. We monitor weather forecasts throughout the season, pre-treat ahead of storms, and mobilize early so your property is clear before business hours.
Services include snow plowing, walkway clearing, deicing and salt application, and emergency response for unexpected accumulation. Seasonal fixed-rate contracts are available for property managers who need predictable winter budgeting without placing emergency calls during storms.
