New Construction Inspection in Johnston

New Construction Inspection in Johnston, Polk County, by Closer Look Inspectors. Johnston is a fast-grown northwest-metro suburb of 1990s-2020s subdivisions above the Des Moines River valley, and we calibrate every visit to that.

A new construction inspection gives a newly built home an independent review before your final walkthrough — because builders miss things, and an outside set of eyes catches them while the fix is still the builder's responsibility.

Tuned to Johnston.

Johnston housing runs to 1990s-2020s subdivisions with pockets of older acreage stock, across the newer subdivisions and the Des Moines River valley edge, on Des Moines Lobe till breaking into the river valley slope — and that mix shapes what a new construction inspection here needs to find. Instrument-grade tools, a local eye, every visit.

Local conditions in Johnston

Johnston sits on Des Moines Lobe till — heavy, poorly drained clay that holds water against foundations and moves with moisture, which is what drives basement seepage and foundation cracking across central Iowa. Johnston sits in Polk County, and Iowa has the highest average indoor radon level of any state — the Iowa DNR puts roughly five in ten Iowa homes above the 4.0 pCi/L action level, and Iowa sellers must disclose known radon results on the property disclosure. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Footings here are set below a frost line of roughly 36 to 42 inches, and that annual freeze-thaw cycle drives the settlement cracks and ice-dam wear we calibrate every Johnston visit to find.

Questions

Common questions.

Why inspect a brand-new home?
Even new homes carry defects — flashing, grading and rushed finish work are common. Catch them before you close.
When should it happen?
Before your final walkthrough, so the items land on the builder's punch list.
What should Johnston buyers watch for?
Most of the city is 1990s-2000s stock now hitting its first roof and mechanical replacement cycle, and on heavy lobe till the grading question never goes away. Lots that step down toward the Des Moines River valley add slope drainage and settlement to the read. Radon is the standing Iowa priority — Polk County is Zone 1 and roughly half of Iowa homes test above the action level.
