Service is bounded to St. Louis County and St. Charles County, Missouri — because our P.E. performs every Alumiconn inspection personally, and these two counties contain the densest stock of pre-1974 housing affected by aluminum branch wiring in the region.
We don't expand the service area. Three reasons.
Reason one: our P.E. personally inspects every job. Every Alumiconn certification we issue carries our P.E.'s individual PE seal — not a corporate firm stamp, not a junior engineer's review, not a contracted subcontractor's signature. Bounding the service area to two counties is what makes personal inspection sustainable at our volume.
Reason two: pre-1974 housing density. The St. Louis metropolitan area's housing stock from 1965 to 1973 is concentrated in these two counties — the explosive postwar suburb build-out of Florissant, Affton, Maryland Heights, Webster Groves' eastern half, the unincorporated middle ring of STL County, and the early St. Charles County subdivisions in St. Peters and O'Fallon. Within this footprint we are deeply specialized.
Reason three: 24-hour turnaround. The standard delivery we promise — field visit to sealed PDF within 24 hours — only works if the driving distance from our home base in West County keeps the round trip under an hour. Outside our coverage area the math breaks.
If you have aluminum-wired property outside this area — in Jefferson County, Franklin County, Lincoln County, or further afield in Missouri, Illinois, Arkansas, or Kansas — the Scapular Engineering hub can refer you to a different inspection practice for your geography.
Pre-1974 housing concentration is highest in the middle ring of unincorporated STL County and in the older incorporated municipalities surrounding the city. We cover all of them.

St. Charles County's pre-1974 housing is concentrated in the older sections of St. Charles city and St. Peters — the original streetcar suburbs of the Highway 70 corridor — plus pockets in O'Fallon and Wentzville along the historic Highway 40 alignment.

The City of St. Louis has a much smaller pre-1974 aluminum-wired stock than the county — most city housing predates the aluminum era — but the south-city brick ranches and bungalows built in the late 1960s are sometimes affected.
City coverage focuses on south city neighborhoods (Tower Grove South, Princeton Heights, Holly Hills, Bevo Mill, Lindenwood Park, Boulevard Heights, Holly Hills) where post-WWII brick ranches commonly fall in the affected era. Some north-city subdivisions from the same period (parts of Walnut Park, O'Fallon Park area) also occasionally need certification.
Travel time to and from south city is consistent with our county coverage; we treat city jobs on the same 24-hour standard timeline.
If your aluminum-wired property is outside St. Louis County, St. Charles County, or the City of St. Louis, we won't be the right inspection practice for your job — but the Scapular Engineering hub may be able to refer you to a different practice in our network or to a respected colleague in your geography.

For Illinois-side Metro East jobs (Madison County, St. Clair County, Monroe County), we sometimes take on certifications on a case-by-case basis with rush surcharges to cover the river-crossing travel time. Contact the hub if your job is in one of these areas.
STL Alumiconn is one of six PE-sealed inspection practices operated by Scapular Engineering, P.E. The network covers Midwest housing, FHA, manufacturing, and settlement-package services from a single licensed engineer.
