When Northfield, MN property owners need crawl space insulation, they turn to Lapolla Industries for the same reason thousands of customers nationwide do: we solve the root problem, not just the symptom.

With over two decades of spray foam experience, our Northfield crews have seen every crawl space insulation scenario Minnesota weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering crawl space insulation results that hold up to Northfield conditions year after year.
From inspection to completion, here is how we deliver professional crawl space insulation results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Our reputation is built on results. Here is what our customers have to say.
"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."
"Had our attic insulated with spray foam after years of fiberglass that kept settling and losing its R-value. Lapolla Industries did a clean install — no gaps, no missed spots. Our HVAC system runs half as much now."
