A homeowner in Chapel Hill, NC reached out to Window Works Co. to get a quote for replacing their 30-year-old builder-grade windows. They were ready to upgrade to energy-efficient, long-lasting windows that would match their home’s classic brick architecture, and wanted expert advice on whether to choose full-frame replacements or insert (pocket) windows.
After hearing more about what they were looking for, we introduced them to the Andersen 400 Series — a beautiful blend of quality, durability, and timeless style that fits perfectly with Chapel Hill’s classic home designs.

When to Choose a Full-Frame Window Replacement
If your home still has its original builder-windows, it may be time for a complete upgrade. Full-frame replacements involve removing the entire window, including interior and exterior trim, and replacing it with a completely new frame and glass system.
While this method takes more time and labor than insert installations, it offers the best long-term performance and energy efficiency. In Chapel Hill and surrounding areas, homes built before 2010 often lack proper insulation around the window cavity. During a full-frame window installation, we fill that space with non-expanding foam insulation, dramatically improving comfort, soundproofing, and energy savings.
Why the Andersen 400 Series Is a Top Choice for Chapel Hill Homes
For this homeowner, we recommended the Andersen 400 Series. These windows are available in standard sizes, which means we can often complete the window installation without needing costly custom fabrication.
Each 400 Series window is made with a wood interior and a durable vinyl or Fibrex® composite exterior, creating a low-maintenance, high-performance product that resists rot, peeling, and warping. The result? Beautiful wood interiors that can be prefinished to match your home, and weather-resistant exteriors that stand up to the North Carolina climate.
Energy Efficiency That Lasts a Lifetime
Andersen’s high-performance Low-E4® glass helps block up to 98% of harmful UV rays, reducing heat gain in the summer and heat loss in the winter. Combined with full-frame installation and proper insulation, homeowners often notice lower energy bills and more consistent indoor comfort year-round.
When you invest in quality replacement windows like the 400 Series, you’re not just improving your home’s appearance; you’re adding long-term value and efficiency that can last a lifetime.
Customizing Your Window Layout
During our initial conversation, the homeowner also mentioned an interest in replacing two double-hung windows with a large picture window overlooking the backyard. Our team is licensed to confirm that this type of conversion is possible in most homes. We always inspect the framing during the measurement phase to ensure your new design is both safe and stunning.
