Mission built out right after the war, which makes its housing stock some of the oldest in Johnson County. Foundations here have been working against the clay since the 40s.
Crawl Space Waterproofing in Mission, KS | Heartland Foundation Repair

Crawl spaces in Mission are ground-zero for moisture problems. The clay soil releases moisture constantly, and in Johnson County's humid summers, the air coming through those open vents makes it worse. Encapsulation stops the cycle completely.
Homes from the '40s through the '60s hitting the age where foundations start showing stress. Cracks, water, bowing walls — we've fixed all of it in Mission.

Frequently Asked Questions — Crawl Space in Mission
Do older Mission homes have crawl space problems?
Some of these post-war ranches and bungalows have crawl spaces or partial crawl areas, and after 70-plus years they hold moisture from the clay and any open vents. That dampness softens joists and rises into the small living space as a musty smell people often can't track down.
What does encapsulation involve for a Mission home?
A heavy-duty vapor barrier on the floor and walls, sealed vents, and a dehumidifier sized to the space, plus drainage and structural support where needed. In these compact homes the crawl space is often small, so the job is usually quick once we're in.
Will this fix the musty smell in my older Mission home?
Usually, yes. In these older homes the musty smell almost always comes from a damp crawl space or unfinished lower area, with that air rising through the house. Sealing and dehumidifying the space stops the moisture and clears the smell.
How long does crawl space work take?
Most Mission jobs run one to two days, and the smaller crawl spaces common here often finish on the quicker end. A basic vapor barrier is fast, while full encapsulation with a dehumidifier takes a bit longer. We give you a clear timeline before we start.
