Our Services
Windows, Doors & Sliders
Serving Greenport, the North Fork & Shelter Island, NY.
Expert installation of windows, entry doors, and gliding sliders.
Overview
What’s involved
We supply and install energy-efficient windows, entry doors, patio sliders, and storm doors built to stand up to coastal weather. Installation matters as much as the product, so we flash, insulate, and seal every opening for tight, draft-free performance and clean interior and exterior trim. Whether you are replacing a few tired windows, upgrading to impact-rated units, or adding a slider to open a room to the backyard, we handle the full job, including hauling away the old materials.
Is it time?
When do you need it?
Consider new windows and doors when you feel drafts, see condensation between panes, struggle with sticking sashes, or want to lower heating and cooling bills. Replacement is also smart during a remodel, after storm damage, or when you simply want a fresh look and better security. Sliders and new entry doors are a fast way to add light, curb appeal, and value.

Good to know
Frequently asked questions
Do you install impact-rated or storm-resistant windows?
Yes. We install impact-rated and storm-ready windows and doors, which is worth considering given the North Fork and Shelter Island's exposure to coastal storms.
Will new windows really lower my energy bills?
Modern energy-efficient units paired with proper sealing and insulation noticeably reduce drafts and heat loss, which helps keep heating and cooling costs down year round.
Can you match the style of my existing home?
Absolutely. We help you choose window grilles, door styles, and finishes that suit your home, then trim everything cleanly inside and out.
