How to estimate an attic insulation job before calling contractors

How to estimate an attic insulation job size and scope? Smart homeowners in Jonesboro are doing their homework before calling contractors — and it's saving them time and money.

Here's your 15-minute attic assessment: First, measure your attic's square footage (length × width). Don't forget odd corners or bonus rooms above garages. Next, check your current insulation depth with a ruler. In Northeast Arkansas (Climate Zone 3A), you need R-38 minimum per IRC code — that's about 12 inches of blown cellulose or 6 inches of spray foam.

Calculate the gap: If you have 4 inches of old fiberglass batts (roughly R-13), you're missing R-25 of performance. For a 1,200 SF ranch, adding blown cellulose costs around $2.50/SF installed, while spray foam runs $4-6/SF but seals air leaks too.

Red flags to note: Dark stains on existing insulation (air leakage), compressed batts, or wet spots. Also check for recessed lights without IC ratings — these create fire hazards with blown insulation.

June's perfect timing for this project. Crews can work comfortably, and you'll feel the energy savings when July's heat hits. A properly insulated 1,200 SF home typically saves $400-600 yearly on HVAC costs in our climate.
