Yakima attic air sealing checklist
This guide helps Yakima homeowners organize attic air sealing questions before comparing spray foam, blown insulation, or broader weatherization work.
Where attic air leaks usually start
- Ceiling penetrations around can lights, bath fans, plumbing, wiring, and attic hatches.
- Top plates, dropped soffits, knee walls, and chase openings that connect living space to the attic.
- Gaps near ducts, chimneys, flues, and framing changes that need appropriate fire-safe detailing.
- Wind-washed insulation near eaves where baffles, air barriers, or blocking may be needed.
Questions to ask before insulating
- Should air sealing happen before new insulation is installed?
- Are ventilation paths clear from soffits to roof vents?
- Is there old insulation, pest damage, moisture staining, or roof leakage that should be corrected first?
- What R-value target is appropriate for the attic assembly and budget?
Photos and notes to collect
- Attic hatch, access path, and headroom limits.
- Existing insulation depth and problem areas.
- Drafty rooms, high utility bills, ice or condensation history, and comfort complaints.
- Any remodel, roofing, HVAC, or electrical work planned at the same time.
