Blown-In Attic Prep: Access, Air Leakage, Other Work
Before adding blown-in insulation, list the other work your attic needs. Roof leaks, air leakage, ducts, wiring and ventilation can affect preparation and sequencing. Share planned projects and existing reports so each provider knows what remains unresolved. Qualified reviewers should establish the technical requirements; more insulation alone does not complete that review.
Add vs Replace Blown-In Insulation: Existing Material Checks
Before adding blown-in insulation, review the condition of the existing material. Moisture, contamination, air leakage and unfinished repairs may change the plan. Dry material suitable to remain may support an addition, while other areas may need removal or a different approach. Ask the reviewer to document the findings behind the recommendation.
