Insulating Where the River Rises

Spray Foam Insulation in Aitkin cannot ignore the river and its floods. The Mississippi River flows through the northern edge of the city, and Wikipedia records a 1950 flood that topped 20 feet, a 2012 flood of nearly 19 feet, and downtown flooding in 2023 after record snowfall. When basements and crawl spaces take on water, the insulation in them is usually ruined.

What wet insulation does

Fiberglass batts and loose fill that get soaked lose most of their value, hold moisture against wood and can grow mold. After water has been in a basement or crawl space, we recommend removing wet insulation, letting the structure dry and then reinsulating. Removal is one of the services we offer, and we will be honest about what can stay.

Choosing materials for damp spaces

Fibrous insulation holds water; closed-cell foam mostly sheds it and also slows vapor. That makes it a common choice for basement walls, rim joists and crawl space walls in damp areas. It is not a fix for active leaks, and it should only go on surfaces that are dry. If water is still coming in, drainage needs attention first.

The cold side of the equation

Aitkin's climate table lists a record low of -47F, and the state's residential energy rule gives Aitkin a winter design temperature of -24F, one of the colder values on its list. Aitkin County is in Climate Zone 7 on Minnesota's code map.

Seasonal homes in the county

Aitkin County had 13,944 housing units in 2020, and 48.4% were vacant on census day. The city itself is more year-round, with 10.5% of its 1,081 units vacant. For seasonal places, checking crawl spaces after spring melt is a good habit.

Aitkin Questions

My Aitkin basement flooded. Does the insulation need to come out?

If fibrous insulation got wet, it usually should be removed so the walls and framing can dry. We can check what got wet and quote removal and replacement.

Is closed-cell foam waterproof?

It resists water far better than fiberglass or cellulose and slows vapor, but it is not a waterproofing system. Leaks and drainage need to be fixed first.

How long should I wait after flooding before insulating?

Until the surfaces are fully dry. That can take days or weeks depending on the space. We check moisture before we spray.

Can a crawl space near the river be insulated?

Yes. Many crawl spaces are insulated on the walls with a vapor barrier on the ground, which keeps the space drier. We look at drainage and grading first.
