Window Universe

Window Universe is a window and door dealer rather than a traditional installer: its Manchester, NH market page sells replacement and new-construction windows and entry and patio doors to homeowners across Manchester and Southern New Hampshire through itemized pricing sent by email, with a warehouse and showroom on East Industrial Park Drive and installation handled by the manufacturer's installation service. The company says it was founded in 2008 by Dan Schweihs and Bianca Medrano, both described as 20-plus-year industry veterans, and that it serves Manchester, Nashua and Concord. The only independent account on file is a June 2025 r/newhampshire commenter who bought nine windows, one an upgraded twin casement, for about $10,000, and who was not impressed with the installation — adding that a handy homeowner could install the windows themselves. That is a single voice, but it points at the one part of the job the company outsources. What to know before calling: there are no customer reviews on file, so the pricing-by-email model and the third-party installation are the things to ask about directly — who installs, what the warranty covers, and what the itemized quote includes. A reasonable place to price-shop windows in southern New Hampshire; the installation leg is where the one customer account fell short, so get that arrangement in writing.
