Licensed and Insured
Mikita Door & Window has been installing doors, windows, siding, and roofing for Long Island homeowners since 2000. We are a family-owned company based in Freeport, and we carry products from Andersen, Pella, and ProVia. With over 25 years of experience and 378 five-star Google reviews, we handle every project with our own crew. No subcontractors, no middlemen. Long Island electricity rates run roughly 35% above the national average, so properly installed, energy-efficient windows and insulated doors are not a luxury here. They are a necessity. Call (516) 867-4100 or visit our showroom at 136 W Sunrise Hwy in Freeport for a free in-home estimate.
Replacement Windows
Old, drafty windows drive up your PSEG bill every month and let street noise into your home. We install Andersen, Pella, and ProVia double-hung, casement, sliding, and specialty windows built to handle Long Island’s coastal air. Every window comes with a manufacturer warranty and our lifetime labor guarantee.
Entry Doors
Your front door is the first thing guests see and the last line of security when you lock up at night. We install fiberglass, steel, and wood entry doors from ProVia, custom-measured at your home and fitted by our own crew. No subcontractors touch your entryway.
Patio Doors
A sticking patio door or a broken track makes your backyard feel disconnected from the rest of your home. We install sliding, French, and multi-panel patio doors sized to your opening and sealed for Long Island weather.
Storm Doors
South Shore nor’easters rip through screen doors and thin storm panels every season. We carry full-view, retractable screen, and ventilating storm doors built to take the wind off the Atlantic without blocking your natural light.
Bay and Bow Windows
Bay and bow windows open up a room, add natural light, and create usable space along the wall. We custom-build and install three-panel bay and four-to-six-panel bow configurations with structural support brackets and proper flashing for Long Island rain.
Exterior Doors
Side doors, back doors, basement entries, and garage-to-house doors take daily abuse and weather exposure. We install fiberglass, steel, and wood exterior doors with proper weatherstripping, deadbolt-ready hardware, and insulated cores built for Long Island’s climate.
Door Installation
Whether you need a single front door hung or every exterior door in your home replaced, our crew handles the full job. We remove the old door, inspect the frame, install the new unit, and test the hardware before we leave. No subcontractors on any door project.
WHY CHOOSE US
Mikita Door & Window is EPA Lead Safe Certified and an Energy Star Award winner. What separates us from the national franchises and the one-truck operations is simple: Michael Nocella, the owner, is on every single job. We do not use subcontractors. The same crew that measures your opening is the crew that installs your door or window. We carry Andersen, Pella, and ProVia products because they are manufacturer-backed, energy-rated, and built to handle coastal conditions. Our Freeport showroom is open six days a week so you can see and touch every product before it goes into your home.
Long Island’s salt air from the Great South Bay and the Atlantic corrodes cheap hardware, warps thin frames, and breaks down weatherstripping faster than inland climates. That is why material selection matters here more than most places. We recommend vinyl, fiberglass, and composite frames tested against coastal humidity. When you call, you get a real person, a fast callback, and a crew at your door with a free written estimate. You will know the price before any work starts, and you will not pay until the job is done and you are satisfied.
