Fargo sits on the flat floor of the Red River Valley, where early-1900s frame foursquares downtown near NDSU share the landscape with 1960s ranches, split-entry bi-levels, and newer two-stories over basements built on heavy gumbo clay. Every winter, attics climb to 130 degrees in July and plummet to 30 below in January, and almost every home builds ice dams while basements face spring flood risk. That extreme swing, year after year, means moisture and air leaks in attics, crawl spaces, rim joists, and closed walls become a real problem fast.
Fargo Spray Foam Insulation has been sealing and insulating homes across Fargo and the surrounding area since 2012. We know the neighborhoods, the building stock, the climate, and what actually stops the heat loss, the cold seeping in, and the moisture that follows. We show up with a written estimate that names the R-value and thickness you are paying for, we do the work right, and we stay reachable when questions come up after we leave.
Spray Foam Insulation in Fargo (58102)
The homes that make up Fargo have distinct insulation problems. Downtown and near NDSU, the 1920s and 1930s frame houses have balloon-framed walls with empty cavities and attics that were never properly filled. The 1950s and 1960s capes and ranches across Clara Barton, Jefferson, Lewis and Clark, and north Fargo have knee-wall attics and original fiberglass that has settled flat or gotten damp. South Fargo and West Fargo's split-entries and bi-levels from the 1970s and 1980s have cantilevers and rim joists that leak cold air at every joist bay, and newer two-stories over basements often have three-car garages with heated spaces directly below uninsulated attics. In every case, the Red River Valley climate does the damage: vapor drive pushes outward most of the year, humidity in summer condenses on cold surfaces in winter, and the long cold season makes every air leak expensive.
We spray attics, crawl spaces, rim joists, closed walls, garages, and metal buildings across Fargo with closed cell and open cell foam, pull out old and contaminated insulation, and seal the air leaks that foam alone will not fix. Our fully insured crews have been doing this work in Fargo neighborhoods for over a decade.

How a Job Works in Fargo
We start with a free on-site assessment. You walk us through the problem: a room that never gets warm, a cooling bill that has become unaffordable, moisture or condensation you have seen in the attic or crawl space, or insulation that has failed and needs to come out. We look at the space, talk through what is there now, and explain what we can do and what it will cost. You get a written estimate with the R-value and thickness specified, the price broken down, and a timeline.
On the day of the work, we set up mechanical ventilation in the space being sprayed and keep it running through the cure window. If old insulation has to come out first, we remove it, bag it, and haul it away. We spray the foam to the thickness and density the estimate names, let it cure, trim the excess, and install the ignition and thermal barriers that your local building code requires. The space stays ventilated until the cure is complete, typically twenty-four to forty-eight hours, and we provide a re-entry window in writing.
We clean up the property, haul away all waste, and walk through the finished work with you. You are left with a sealed, insulated space and a clear record of what was done.
Pricing for spray foam insulation in Fargo depends on the size of the space, the R-value and thickness you need, whether you are using open cell or closed cell foam, and what has to be removed before we can spray. A typical attic top-up runs from $1.50 per square foot. Wall injection foam starts around $2 per square foot. A crawl space spray foam job typically begins at $2,500. Rim joist and band joist sealing starts at $650. If old insulation has to come out first, removal runs from $950 depending on the volume and condition. Every job is measured on site and priced honestly. Call us at (701) 501-6701 for a free estimate, and we will walk you through the cost factors and the timeline for your specific space.
