How the Calculator Works
This is not a formal quote for RetroFoam injection foam insulation for your existing exterior walls, but rather a rough idea of what your project may cost for planning purposes.
This calculator determines a rough cost for the existing exterior walls of a typical one or two story home in the Denver area.
Please note, projects sometimes fall below our minimum job cost.
Since every project is different, some of the factors that may impact the cost include:
- 2x4 vs 2x6 Walls
- Number of Stories
- Inside Installs
- Partial Installs (Fewer than Four Exterior Walls)
- Removal of Old Insulation
- Job Location
- Qualifying Discounts
- Potential Xcel Rebates
