Andersen Windows
Northcrest Window & Door Specialists installs Andersen windows — the most trusted window brand in America. Every Andersen window we install is a full-frame replacement, meaning we remove the old window down to the rough opening, inspect for rot or moisture damage, and install a brand-new, properly sealed window built for New Hampshire’s climate. We carry five Andersen product lines to match every home style and budget, from entry-level to fully custom.
100 Series
The 100 Series is Andersen’s entry-level line, built from Fibrex® material — a proprietary structural composite made from 40% reclaimed wood fiber that is stronger than vinyl and more stable than wood. It will not rot, warp, or crack, and holds paint longer than wood. The 100 Series offers casement, awning, single-hung, gliding, picture, transom, and specialty window styles. Available in white and sandtone exterior colors with matching interiors, it delivers lasting performance at an excellent value.
200 Series
The 200 Series is Andersen’s best-value clad-wood window — a wood interior with a low-maintenance exterior cladding. It focuses on the most popular styles and sizes to deliver quality and warmth without overwhelming complexity. The 200 Series offers tilt-wash double-hung and gliding window styles. The tilt-wash sashes tilt inward for easy cleaning from inside your home. Energy efficient and ENERGY STAR® certified, the 200 Series is a smart upgrade from older wood or aluminum windows.
400 Series
The 400 Series is Andersen’s most popular line — the window contractors trust most in America. It features a wood interior for warmth and beauty, with a durable exterior that requires minimal upkeep. The 400 Series offers a wide range of styles including casement, awning, Woodwright® double-hung, tilt-wash double-hung, bay and bow, gliding, and specialty windows. Multiple exterior color options, grille styles, and glass packages are available, making it an ideal fit for most New Hampshire homes.
A-Series
The A-Series is Andersen’s premium architectural line, designed in collaboration with architects to achieve precision matching sight lines, matching glass setbacks, and fine-tuned proportions. It is Andersen’s best-performing and most energy-efficient window, with composite exteriors that withstand the harshest conditions. Styles include casement, awning, double-hung, picture, transom, and specialty windows, available in a wide range of sizes and custom configurations. If design detail matters, the A-Series delivers.
E-Series
The E-Series is Andersen’s fully custom architectural line — built to your exact specifications with unlimited design freedom. Choose from 50 standard exterior colors, custom colors, or anodized finishes. Select interior wood species from a broad range including options sourced on request. The E-Series offers casement, French casement, awning, double-hung, bay and bow, gliding, and specialty windows in virtually any custom shape or size. If you can imagine it, Andersen can build it.
