Is $1,801 to install blown-in fiberglass insulation to achieve r-49 with attic hatch cover and baffles a fair price?

Project Details

The homeowner is looking to top-up 16-18 inches of fiberglass over existing 30-year-old insulation in an approximately 1100 sq ft attic. They are questioning if the price is reasonable and if they should seal plumbing/electrical gaps before proceeding.

Quote Details

Complete attic insulation upgrade including: - Installation of Thermal Zippered Attic Hatch Cover (DraftMaster) to seal the attic door - Installation of baffles on rafters to ensure proper air flow and prevent soffit coverage - Addition of R-26 blown-in fiberglass insulation to achieve a total of R-49 - Sealing of visible attic floor penetrations - Cleanup of mess and unused materials - Use of rulers every 300 square feet to validate insulation height
