Cottage Grove Replacement Windows & Installation
From the 1970s ramblers to the 90s and early-2000s two-stories, a lot of Cottage Grove homes are still heating southeast-metro winters through original or first-round windows that have started to fog, stick, and leak air. Ungerman installs energy-efficient replacement windows throughout Cottage Grove with one licensed team, from measurement through final trim and cleanup, and we’ve served the southeast metro since 1977.
Windows built for a Cottage Grove winter
Older Cottage Grove homes were built before today’s insulated glass, and even the newer builds are now on aging double-pane units with failing seals. We fit the window to the house: double- and triple-pane glass, low-E coatings that hold heat through a river-valley January, and styles from double-hung to casement to picture windows. With so many homes here built over finished basements, cutting the drafts up top makes the whole house more comfortable — and replacing every window at once delivers the biggest efficiency gain and a consistent look from the street.
