Our standard cleaning covers the areas that matter most. Here's exactly what our crews handle room by room.
Mount Sinai is one of the North Shore's quietest and most desirable hamlets — a waterfront community in the Town of Brookhaven where families put down roots and stay for generations. Bounded by the Long Island Sound to the north and Mount Sinai Harbor to the east, the hamlet offers a way of life that revolves around the water, the local school district, and the kind of neighborhood where people still wave from their driveways. Cedar Beach draws crowds in summer, but the rest of the year Mount Sinai is calm, residential, and deeply private.
Homes here range from classic mid-century ranches and colonials along Route 25A and Shore Road to newer developments in gated communities like The Hamlet at Willow Creek. Living on the Sound means salt air, seasonal humidity, and the constant battle with sand, pollen, and moisture that coastal North Shore homes face year-round. Our crews know these challenges and use Green Seal certified products that handle all of it while staying safe for children, pets, and the environment.
Whether you're a family in the top-rated Mount Sinai School District, a boating enthusiast who'd rather spend Saturday on the harbor than vacuuming, or a retiree enjoying the trails at Heritage Park — we're here to keep your home spotless so you can enjoy everything this North Shore gem has to offer.
Pricing is based on your home's size, condition, and the service type you choose. Here are our general starting ranges.

We're right by the harbor and the salt air and sand are relentless. Teresa's crew comes every two weeks and our colonial always looks and smells amazing when they leave. They've been cleaning for us for over three years — wouldn't switch to anyone else.
Booked a deep clean before a family party and the house looked incredible. They got every corner — under furniture, inside the oven, even the window tracks. Our guests kept asking who we use. Can't say enough good things about Teresa's team.
Just moved into a place off Shore Road and hired Teresa's for a move-in clean. They made a 30-year-old house feel brand new. Cabinets, bathrooms, everything was spotless. Now we have them on a bi-weekly schedule and couldn't be happier.
