Full window replacement for New Jersey homes

Sometimes a repair isn’t enough, especially when your old windows are beyond saving or simply can’t keep up with New Jersey’s shifting seasons. At WindowServ, we provide full-service window replacement that upgrades your home’s look and performance in one go. We don’t just swap out units; we make sure your new windows are perfectly integrated into your home to stop leaks, kill noise, and slash your energy bills.

Modern windows built for the NJ climate

We install high-quality, energy-efficient windows designed to handle everything from coastal humidity to freezing winter winds:

  • Energy Star certified units. Upgrade to modern double or triple-pane glass with Low-E coatings. These windows reflect heat in the summer and trap it in the winter, keeping your HVAC system from working overtime.
  • Vinyl, wood, and composite frames. Whether you want the classic look of real wood for a historic home or the zero-maintenance durability of high-grade vinyl, we help you choose the right material for your lifestyle and budget.

Precision installation that lasts

The best window in the world will fail if it’s installed poorly. We take the time to do it right:

  • Full-frame replacement. We don’t just slide a new window into a rotting old frame. We inspect the opening, replace any damaged structural wood, and ensure the new unit is shimmed, insulated, and flashed correctly.
  • Airtight sealing and insulation. We use professional-grade foams and high-end caulking to eliminate the gaps that cause drafts. Our goal is a seamless fit that looks like it’s always been part of your house.
  • Custom styles for every room. From expansive bay windows and sleek sliders to traditional double-hung and casement windows, we offer a wide range of designs to boost your home’s curb appeal.

The WindowServ promise

Replacing your windows is a big investment, and we treat it that way. We keep our workspace clean, stay on schedule, and walk you through the operation of your new windows before we consider the job done. With WindowServ, you’re not just getting new glass—you’re getting a quieter, more secure, and significantly more efficient home.
