11-Month Warranty Inspection in Johnston

11-Month Warranty 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.

An 11-month warranty inspection times a full review to the end of a builder's first-year warranty — so the settlement cracks, nail pops and grading issues a first Iowa winter reveals get repaired on the builder's dime.

Local housing

Homes in 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 11-month warranty inspection here needs to find.

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 every Iowa county is EPA Radon Zone 1. Iowa HHS reports Iowa has the largest percentage of homes above the 4.0 pCi/L action level of any state — 71.6 percent in the Iowa Radon Survey — and the Iowa seller disclosure form asks for any known radon test results. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Iowa leaves frost depth to the local building code rather than one statewide number, and the annual freeze-thaw cycle drives the settlement cracks and ice-dam wear that Johnston-area homes face.

Questions

Common questions.

When exactly do I schedule it?
Around month eleven, leaving time to file the report before the one-year warranty closes.
What does it find?
Issues a full freeze-thaw cycle exposes — cracking, nail pops, and HVAC and grading items.
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 Iowa HHS reports 71.6 percent of Iowa homes test above the 4.0 pCi/L action level.
