In Walker, where heavy snowfall and extreme cold are the norm, attic insulation is the most impactful single upgrade you can make. Most lake cabin homes in Walker from the 1930s-1960s resort town era have only R-19 to R-30 of attic insulation — far below the R-49 to R-60 recommended for this climate. That gap costs Walker homeowners hundreds of dollars in wasted heating every year.
RetroGreen's attic insulation process starts with thorough air sealing — we close every bypass that allows heated air to escape into the attic, including around light fixtures, plumbing stacks, bathroom fans, and attic hatches. This is especially critical in Walker, where ice dams form when heat escaping through the attic melts roof snow that refreezes at the eaves. Then we blow in insulation to reach the recommended R-49 to R-60, creating a uniform blanket across the entire attic floor.

Key Benefits
Dramatic Energy Savings
Sealing the attic envelope cuts heating and cooling costs by 20-40%. Most homeowners see the impact on their very first energy bill after installation.
Ice Dam Prevention
Spray foam keeps the roof deck at a consistent temperature, stopping the melt-freeze cycle that creates ice dams and causes costly water damage to gutters and interiors.
Comfortable Upper Floors
Rooms directly below the attic maintain a consistent temperature instead of swinging between extremes. No more space heaters in winter or window ACs in summer.
Moisture and Mold Protection
Closed-cell spray foam acts as a vapor barrier, preventing the condensation and moisture buildup that leads to mold growth and wood rot in attic framing.
