Elevate your home’s comfort and curb appeal with handcrafted bay, bow, and garden windows from The Window Source of the Lowcountry. Whether you live in Charleston’s historic district, a beachfront home on Hilton Head, or anywhere throughout Mount Pleasant and the surrounding coastal communities, our specialty windows blend timeless elegance with practical functionality—making them a smart investment for homeowners looking to enhance their home’s style, space, and value.

From full renovations to simple window replacements, we offer fully customizable options—installed by skilled local professionals who care about every detail and understand the unique requirements of coastal South Carolina homes.

Bay Windows: Add Light, Space, and Character

Bay windows are a classic way to make your home feel more spacious and open while complementing both historic Charleston architecture and modern Lowcountry designs. These windows extend outward, creating a panoramic view of your garden, marsh views, or ocean vistas—perfect for creating a cozy nook for reading, relaxing, or sipping your morning coffee while enjoying coastal breezes.

A traditional bay window includes a large center picture window flanked by double-hung or casement windows, giving you the best of both natural light and ventilation. Every window is custom-built to match your home’s unique layout and aesthetic, whether you’re in a Sullivan’s Island cottage or a Daniel Island estate.

Bow Windows: A Graceful Curve and a Wider View

Looking for a softer, more rounded look that complements coastal architecture? Bow windows feature three to six equal-size window units that gently arch outward from your home’s exterior. Like bay windows, they welcome in abundant sunlight and beautiful Lowcountry views—but with a curved, more elegant touch that’s perfect for homes on James Island, Johns Island, or Kiawah Island.

Add optional casement windows for fresh ocean airflow and create a sweeping, custom view that captures the natural beauty of coastal Carolina living.

Upgrade Your Picture Window to a Bay or Bow

Thinking about a design upgrade for your Summerville home or Folly Beach retreat? Most picture windows can be replaced with a stunning bay or bow window without major structural changes. This simple enhancement can add dimension, brighten your home with natural coastal light, and boost curb appeal throughout the Lowcountry. At The Window Source of the Lowcountry, we make sure your new windows integrate seamlessly with your existing home or help you design a custom overhang or roof for an extra touch of elegance.
