Is $15,000 to spray foam insulation for crawl space, dormers, and attic a fair price?
Project Details
I recently had an air test done on my 1960s block/stucco house. The basement does get wet with heavy rain, but I have a sump pump and a dehumidifier. I think the basement logic for insulation seems sound given the low quality insulation and moisture. However, the dormer/attic part feels wasteful because the insulation there is much newer and appears well-installed; I understand air sealing is helpful, but tossing good insulation seems unnecessary. I'm also concerned about sealing the attic vents and spraying the roof joists, as it gets very hot and humid here, and I have asphalt shingles. The price is significantly higher than I was expecting.

Spray foam attic with open-cell insulation
This option includes the removal of existing blown-in insulation and the application of open-cell spray foam insulation to the attic roof line. This type of foam is considered standard in the South due to its performance in hot-humid climates. It offers several benefits over closed-cell foam, including: - Safer Moisture Behavior: Allows the roof deck to dry inward and reveals roof leaks. - Avoids Structural Stress: Flexible and low-density, it does not shrink or pull on roof decking. - Better for Retrofit Fit & Air Sealing: Expands significantly (approx. 100x) to fill gaps completely. - Easier to Modify Later: Soft and easy to remove for future work. - More Cost-Effective: Achieves excellent thermal and air-sealing performance for significantly less money.
