At Complete Exterior, we provide professional window installation and replacement services that enhance the look, comfort, and efficiency of your home. Whether you’re building new, upgrading outdated windows, or replacing damaged units, our team has the experience and craftsmanship to deliver results that last. We work with top manufacturers to supply energy-efficient windows designed to withstand New Hampshire’s climate. From classic double-hung windows to custom specialty designs, we ensure every installation complements your home’s style while improving performance.
Energy efficiency is one of the most important factors when choosing new windows. Drafty or outdated windows can lead to high energy bills and an uncomfortable home. That’s why we install modern, insulated, and ENERGY STAR®-rated windows designed to reduce heat loss in winter and keep your home cool in summer. With professional sealing and precision installation, our windows maximize efficiency, saving you money while making your home more comfortable year-round.
If your windows are difficult to open, show condensation between panes, or allow drafts, it may be time for a full window replacement. Our team carefully removes old windows and installs durable replacements that increase curb appeal and add long-term value to your property. Replacement windows not only refresh the appearance of your home but also improve security and noise reduction. We provide a wide range of options to match your budget and design preferences.
Every home is unique, and your windows should reflect that. Complete Exterior offers a variety of window styles including double-hung, casement, slider, picture, bay, bow, and specialty shaped windows. For homeowners seeking timeless charm, we offer traditional designs; for those wanting a modern upgrade, we provide sleek, low-maintenance vinyl and composite windows. Our experts guide you through design and finish selections to ensure your new windows complement both the interior and exterior of your home.
At Complete Exterior, we only work with window brands that are proven to deliver long-lasting performance and style.
