WINDOWS & DOORS
Windows & Doors in Charleston, SC — Coastal-Grade, Energy-Efficient
In coastal South Carolina, windows and doors work harder than anywhere else in the country. They face salt air corrosion, hurricane-force winds, intense summer heat, and relentless UV exposure — all while being asked to keep your home energy-efficient, comfortable, and beautiful. Choosing the wrong product means premature failure, costly replacement, and years of frustration. Choosing the right one means a lifetime of performance and lasting curb appeal.
At Charleston Design Center, every window and door in our lineup has been selected with the Lowcountry in mind. Our team understands the specific demands of coastal construction, the building codes that govern high-wind zones, and the products that have proven themselves in homes from the Outer Banks to the Florida Keys. We sell, and we install — so we are accountable for the products we recommend.

Our window selection spans a complete range of styles, materials, and performance ratings — all chosen for their suitability in coastal and high-humidity environments.

Energy Performance
South Carolina's hot, humid summers make window energy performance a priority. We help you understand and select based on U-factor ratings, Solar Heat Gain Coefficient (SHGC), and Low-E glass coatings that block radiant heat without sacrificing natural light. The right windows can meaningfully reduce your cooling costs year after year.
Doors That Make a Statement and Stand the Test of Time
Your front door is the first thing guests see and the last line of defense against coastal weather. Your interior doors define the flow and feel of your home. Our door selection covers every application — entry doors, sliding glass doors, French doors, patio doors, interior doors, and specialty applications — with options to suit every architectural style from traditional Lowcountry to contemporary coastal modern.
Entry Doors
We carry entry doors in fiberglass, steel, and wood — each offering distinct advantages in coastal conditions. Fiberglass doors have become the preferred choice for coastal homes: they resist warping, swelling, and corrosion, replicate the look of real wood grain beautifully, and maintain their finish for years. Our entry door selection includes single and double door configurations, with sidelight and transom options that enhance curb appeal dramatically.
Sliding Glass & Patio Doors
For the indoor-outdoor living that defines Lowcountry lifestyle, our sliding glass door and patio door options maximize the connection between interior spaces and exterior living areas. We carry multi-panel sliding glass walls, traditional sliding doors, hinged French patio doors, and folding door systems — all available with coastal-rated hardware and impact-resistant glass options.
Interior Doors
Interior doors have a larger visual impact than most homeowners realize. Upgrading from hollow-core builder-grade doors to solid-core, design-forward interior doors immediately elevates the feel of every room. We carry panel doors, French doors, barn doors, and pocket doors in a range of styles that complement your interior design vision.
Professional Window & Door Installation
We do not just sell windows and doors — we install them. Our professional installation teams bring the expertise and attention to detail that windows and doors demand. Improper installation is the leading cause of performance failures, water intrusion, and premature product degradation. We manage every installation with the care and precision these products deserve, ensuring a weather-tight, perfectly operating result from day one.
