DIY Home Weatherization — FarmPal

Close all windows and doors, turn off HVAC, turn on all exhaust fans (kitchen, bath). Walk through with an incense stick smoke movement reveals air leaks around outlets, windows, plumbing penetrations, and attic hatches.

• 💡 Do this on a windy day for best results
• 💡 Mark every leak location with painter's tape
• 💡 Professional blower door test costs $200-400 and is more thorough

The attic floor is the biggest air leak in most homes. Seal around wiring penetrations, plumbing stacks, recessed lights, and the attic hatch with fire-rated caulk and rigid foam.

• 💡 Wear N95 mask and long sleeves in attic
• 💡 Use fire-rated materials near heat sources
• 💡 This single step often delivers the biggest savings

Apply adhesive foam or V-strip weatherstripping to all exterior doors and operable windows. Replace worn door sweeps.

• 💡 Silicone-based products last longer than foam
• 💡 Check weatherstripping annually it wears out
• 💡 Door snakes work as temporary fix for drafty doors

Add blown-in or batt insulation to reach R-38 to R-60 in attic (climate dependent). Insulate rim joists in basement. Consider blown-in wall insulation for older homes.

• 💡 Blown-in cellulose is affordable and DIY-friendly for attics
• 💡 Always air-seal BEFORE adding insulation
• 💡 Check for rebates many utilities offer insulation incentives

Full window replacement is expensive. Instead, add interior storm windows, window film, or thermal curtains for 80% of the benefit at 10% of the cost.

• 💡 Interior storm window kits cost $5-15 per window
• 💡 Thermal curtains reduce heat loss through windows by 25%
• 💡 Only replace windows that are truly failing (rotting, single-pane, inoperable)
