Attic Insulation in Pleasant Valley, IA
Attic spray foam or blown-in upgrades that actually stop the heat loss.
Why Pleasant Valley homes need attic insulation
Pleasant Valley's newer homes typically have R-30 to R-38 of fiberglass in the attic, which sounds fine but underperforms once you account for air leakage at the top plates and recessed cans. Air-sealing plus a top-up to R-60 is the standard upgrade here and pays back fast.
Your attic is where most homes lose 30-40% of their heating dollars. Old fiberglass batts have R-values on paper but they sit on top of a sea of air leaks: top plates, can-light cans, plumbing stacks, attic hatches. Adding more fiberglass on top does nothing about the air movement underneath.
Your contractor will fix attics two ways. Option A: air-seal the attic floor and add R-49 to R-60 of blown-in cellulose or fiberglass on top — best for vented attics with HVAC in the basement. Option B: spray open-cell foam directly to the underside of the roof deck — best when HVAC, ductwork, or plumbing runs through the attic.

Attic Insulation FAQ
How much attic insulation do I need in Iowa or Illinois?+
Current code in IECC Climate Zone 5 (all of the QC) is R-49 in attics. We typically install R-49 to R-60 to leave headroom for future settling. If we're going spray foam to the roof deck, we install to roughly R-30 of closed-cell or R-38 of open-cell.
Do I need to remove old fiberglass first?+
Usually no — if the existing batts are dry, rodent-free, and laying flat, we air-seal under and around them and blow new insulation right on top. A contractor will only tear out when there's water damage, rodent contamination, or vermiculite (which we then handle as hazmat).
How long does an attic job take?+
Most QC attics are a one-day job: 4-8 hours including masking, air-sealing, and blowing. Larger or cut-up attics can run into a second day.
Will new insulation make my upstairs rooms more comfortable?+
Yes, dramatically. The single biggest comfort complaint we hear is 'the upstairs is 10 degrees hotter than the thermostat in summer.' An air-sealed, properly insulated attic fixes that within a day.
