Our base is Hoffman Estates, and we run calls out through the surrounding towns: South Barrington 2 miles out, Streamwood at 3, Inverness at 4, East Dundee at 5, and Barrington Hills and Hanover Park both around 6. We also cover Roselle and Bartlett at 7 miles, Deer Park, Carpentersville, Sleepy Hollow, and Bloomingdale at 8, and further out to Itasca, Fox River Grove, Wayne, Kildeer, South Elgin, North Barrington, Lake Barrington, Carol Stream, and West Dundee near the 10-mile mark, with Glendale Heights, Algonquin, Wood Dale, Cary, Long Grove, Lake in the Hills, Gilberts, Prospect Heights, and Addison rounding out the edge of where we'll drive. Across that service area there are roughly 431,668 households and about 215,904 owner-occupied houses - a lot of driveways, a lot of different door ages. The climate here is squarely cold-winter country, which is the other half of why doors fail: cold makes steel brittle and grease stiff, and a spring that was already near the end of its cycle count often lets go on the coldest morning of the year, not the mildest.
