What We Do
Houses, townhomes and commercial buildings across the Twin Cities metro. Every job starts with a reading and ends with another one — a system that was never retested is only a pipe on the wall.
A continuous monitor in the lowest lived-in level for at least 48 hours, logging every hour — a curve you can read, not one number that might be a fluke.
Learn More →The standard fix for a Twin Cities basement or slab: suction under the floor, the gaps sealed, a fan outside the living space and a discharge above the roof — built for a Minnesota winter.
Learn More →A dirt crawl space under an addition, a porch conversion or an older house has no floor to stop soil gas. A sealed membrane with suction under it builds the missing one.
Learn More →Placed and collected to fit your inspection window, with a report written for the file — and a straight answer on the date before you book.
Learn More →A second test once the system has been running. Included with every install, and available on its own for a system nobody has checked.
Learn More →An open sump basket or a dry floor drain is a direct line to the soil. Sealing them is what lets a system work — and where cheap installs cut corners.
Learn More →Bigger buildings change the protocol, not the physics — more placements, ventilation systems in the mix and more people who need the report.
Learn More →Dead fans, iced discharges, passive pipes that never worked. We test first, then fix what the reading says is wrong.
