    Window Installation

    New windows going into a home, whether that's a first-time install, alongside a larger renovation, or replacing windows that have reached the end of their service life. We walk through frame material and glass package options during your estimate.

    Window Installation

    General Window Replacement

    For homes where existing windows have failed — cracked seals, fogging between panes, frames that won't stay open or shut properly. Replacement starts with assessing what's actually gone wrong before recommending a fix.

    General Window Replacement

    Vinyl Window Installation & Replacement

    Our most common frame material: lower cost than wood or fiberglass, no painting required, and strong energy performance for most residential budgets.

    Energy-Efficient Window Replacement

    For homeowners upgrading specifically to cut heating and cooling costs — Energy Star-rated glass packages, U-factor and SHGC ratings, and how that pencils out in Connecticut's climate.

    Energy-Efficient Window Replacement

    Skylight Installation

    Adding a new skylight to bring natural light into a room that doesn't currently have one — a different install than replacing a wall window, with its own flashing and structural considerations.

    Skylight Installation

    Skylight Repair

    For existing skylights showing signs of leaking, condensation, or seal failure — a targeted fix rather than a full replacement in most cases.
