Double-Hung Windows in The Florida Keys

Updated on January 6, 2026

Double-hung windows continue to be a reliable favorite in homes across the Florida Keys. Their twin sliding panels allow flexible airflow, and that’s valuable in a climate where comfort depends on control. Unlike fixed windows, these can be opened from the top or bottom, depending on the time of day or room placement. When closed, they form a tight seal that helps reduce energy loss. Our energy-efficient double-hung windows are designed to preserve indoor temperature and help reduce cooling costs, making them a smart investment for any home.

Double-Hung Windows For Florida's Climate

At Lindholm Exteriors, we offer custom double-hung windows built for the demands of salt air, heat, and tropical storms – the sort of conditions you can get in the Florida Keys. The materials we install include vinyl and aluminum, each one selected for long-lasting performance. You can explore all our window frame types on our window replacement page, along with impact-resistant styles that add protection in storm season.

Double-Hung Window Installation with Personal Care

No two properties are the same, and our approach to window replacement reflects that. We begin with a full inspection and a straightforward conversation. Every double-hung window installation is planned around the structure of your home and the conditions it faces year-round. Once we arrive on-site, our crew works efficiently, cleans thoroughly, and checks every window for balance and seal. We aim for more than just a job well done; we want your new windows to improve the way you experience your space. These windows require minimal attention but offer continued comfort. Simple cleaning and the occasional check keep them working for years.

We offer impact-resistant and energy-efficient windows designed to keep your home protected and comfortable. You can also choose frame materials that suit your style and needs, like aluminum or vinyl. As the leading window replacement and installation contractors in the Florida Keys since 1949, we are proud to serve the local communities in the region. We are a family-run business based in Islamorada and BBB-accredited with an A+ rating. To experience what we have to offer, you can call us for your free estimate.
