Minnesota's capital city has some of the oldest residential sewer infrastructure in the state. The St. Paul Regional Water Services tracks main breaks but homeowners own the lateral from the foundation to the city main — typically 40–90 feet of pipe you can't see without a camera.
InterNACHI CMI®Homeowners in St. Paul, Minnesota face a specific inspection reality. Minnesota's capital city has some of the oldest residential sewer infrastructure in the state. The St. Paul Regional Water Services tracks main breaks but homeowners own the lateral from the foundation to the city main — typically 40–90 feet of pipe you can't see without a camera. That's why mold & air inspections in St. Paul require local context, not just generic procedure.
Minnesota basements are mold's natural habitat. Cold, humid, with regular freeze-thaw moisture cycling — and most older MN homes have at least one historical leak or sweating concrete wall. We use spore-trap sampling, moisture mapping with infrared imaging, and lab-validated analysis to identify both visible mold and the airborne spore load that simple visual inspection misses.
St. Paul's bluff topography means many laterals run steep grades into mainlines under cobble-base streets — bellies and offsets at the curb stop are the most common defect we record on Summit Avenue and Highland Park properties.
St. Paul has a population of 311,527 and a median home year of 1946. ZIP 55101 is the primary postal code. The neighborhoods we serve include:
