Attic Insulation in Fargo, ND
Seal and insulate your attic to stop the biggest source of heat loss.
The attic is the #1 source of heat loss in most Fargo homes. Spray foam air-seals it completely, stopping the leaks fiberglass can't and cutting the heat you'd otherwise pay to send straight through the roof all winter.
Your attic is the single biggest source of heat loss in most Fargo homes — heat rises, and if the attic isn't sealed, you're paying to warm the outdoors all winter. Spray foam seals the attic completely, stopping the air leaks that fiberglass simply can't.
A properly insulated attic also helps prevent the ice dams that form during long North Dakota winters and keeps the upstairs comfortable in summer.
We air-seal attics across the metro, including the older homes of Moorhead and Dilworth and newer builds in West Fargo.
- Stops the #1 source of heat loss
- Helps prevent winter ice dams

Attic Insulation — Common Questions
Will attic spray foam stop ice dams on my Fargo roof?
It addresses the cause directly. Ice dams form when heat leaking into the attic melts roof snow that refreezes at the cold eaves. Air-sealing the attic keeps the roof deck cold and even, which is what breaks the cycle.
Should I foam the attic floor or the roof deck?
It depends on whether you want a vented or an unvented (conditioned) attic. Roof-deck foam creates a conditioned attic that's ideal for homes with ductwork or HVAC up there; floor sealing suits a simple storage attic. We recommend the right one on-site.
How much can attic insulation save on heating in ND?
Attic air-sealing is often the fastest-payback insulation upgrade in our climate — many homeowners see a meaningful drop in heating costs after sealing the attic and rim joist alone.
Can you add spray foam over existing attic insulation?
Sometimes — it depends on what's there and its condition. Often, removing old air-leaky fiberglass and starting clean gives a far better seal. We assess this during the free quote.
