The sealed system

How does crawl space encapsulation work in St. Joseph?

Epp's St. Joseph office on Frederick Avenue is close to most of town, and the typical house it serves here was built in 1961. An encapsulation seals that crawl from the ground up: the encapsulation liner covers the floor and climbs the walls, the vents and rim joist gaps are sealed, and a dehumidifier inside the liner keeps the humidity in check. When the framing has already moved, St. Joseph crawl space repair handles it before anything is sealed.

Problem signs

Crawl space encapsulation problem signs we fix in St. Joseph

The signs tied to water in the ground come first here. Based on USDA soil survey data, soil in St. Joseph is about 80 percent clay, and clay can hold water against a wall after rain.

St. Joseph housing

When were St. Joseph homes built?

The U.S. Census Bureau survey counts 33,137 homes in St. Joseph. Half were built by 1961; about 48 percent predate 1960 and 10 percent are from 2000 or later.

Whatever the age of the house, the inspection checks what covers the soil, whether the vents are open and whether water gets in.

Based on NOAA 1991 to 2020 climate normals for St. Joseph Rosecrans Airport, about 6 miles away, precipitation averages 34.8 inches a year. Based on the same NOAA normals for Kansas City International Airport, about 32 miles away, the average July dew point is 67 degrees. In a vented crawl space, water can condense on any pipe, duct or joist that is cooler than 67 degrees.

"I've seen homeowners spend serious money on drainage matting and a sump pump in a vented crawl, and call us a year later because their humidity is still high and their floors still feel cold. The drainage worked. The crawl wasn't fixed. You have to address the moisture envelope, not just the water that pools on the floor."

What we install

Crawl Space Encapsulation solutions for St. Joseph homes

Each item below is one part of the same sealed system, and the inspection decides which parts a St. Joseph crawl space needs. Fixes for water in the ground are listed first.

Cost and scope

What does crawl space encapsulation cost in St. Joseph?

Pricing depends on the size of the crawl, how much water gets in, and whether drainage or a sump goes in first. The free inspection ends with a Customized Repair Estimate that states the scope and the price.

When is crawl space encapsulation not the right fix?

If the posts, beams or joists under the house have moved, crawl space repair comes first, and the sealed system goes in once the structure is sound.
