Our base is in Joplin, and most of our calls come from the close-in areas: Duquesne, about 2 miles out, and Leawood, about 3 miles. We also get regular calls from Airport Drive, Webb City, and Duenweg, all around 5 miles out, and from Carterville at 6 miles and Carl Junction at 7.
Farther out, we cover Loma Linda and Oronogo at about 8 miles each, and we'll take calls as far as Carthage (11 miles), Diamond (12 miles), and out to Neosho, Granby, and Seneca, each around 17 miles. The housing in these outlying towns runs the same general age range as Joplin proper - mostly 1980s and 90s builds across the fourteen named areas we cover - so the failure patterns we see (worn torsion springs, original openers nearing the end of their life) tend to look similar whether the call comes from inside city limits or from one of the farther towns.
If you're not sure whether your address falls in range, call 14172016345 and ask before you book anything.
