The Best Insulation for Existing Homes
Most homes in Colorado are leaking money through their attic. If your insulation is too thin — or missing altogether — you’re paying for air you can’t keep.
RetroFoam of Southern Colorado offers professional loose fill fiberglass insulation services designed to seal in comfort, reduce energy use, and get your home in line with utility standards for rebates.
Before we add anything, we check what you’ve already got. We measure the depth and quality of your existing insulation to see if it's enough. In most cases, it’s not. We'll show you exactly how much material is needed to reach current energy-efficiency standards.
If your attic is under-insulated, we blow in loose fill fiberglass insulation to increase your R-value and help stabilize indoor temperatures. This keeps your heating and cooling systems from working overtime, which means lower utility bills and a longer lifespan for your HVAC equipment
We don’t just dump insulation on top of leaks. Our crew seals attic bypasses and top plates before adding insulation — a critical step for both comfort and rebate eligibility. Without proper air sealing, new insulation can only do so much.
Insulation upgrades often qualify for local energy rebates. We coordinate with your provider and help you handle the paperwork. Plus, under the current federal guidelines, you can claim insulation improvements for tax credits through 2032. We’ll show you exactly what you need to file.
Old or ineffective attic insulation can do more harm than good. If your attic needs a clean slate, we offer insulation removal and disposal (as long as it’s non-hazardous). From there, we can rebuild your thermal barrier with new blown-in fiberglass or explore other options like spray foam.
