Spray foam insulation is a smart choice for homeowners who notice uneven temperatures, high energy bills, or drafts in their home. If you’re experiencing humidity issues, moisture buildup, or mold in your crawlspace or attic, insulation upgrades can make a big difference. Over time, old or damaged insulation can lose its effectiveness, allowing air and moisture to move freely. German & Son Construction recommends spray foam insulation when you want long-term protection and efficiency that works year-round, especially in humid Southern climates.
