Inspector's check · Attic
Is the insulation deep and even?
Insulation should be level and roughly 12 to 16 inches deep in cold climates, covering the tops of the ceiling joists. Look for bare spots, compressed areas and gaps near the eaves.
Safety first: Step only on the joists or on boards laid across them; the ceiling below won't hold you. Wear a dust mask and gloves. If the insulation is loose, gray-brown and pebbly like gravel (vermiculite), don't disturb it: it can contain asbestos, so have it tested before anyone works up there. Skip the attic on hot summer afternoons.
Why it matters
Thin insulation raises heating and cooling bills and makes rooms below uncomfortable.
If it's a problem
An inspector would write it up as “Attic insulation is thin or uneven” and rate it keep an eye on. Your options, with rough U.S. costs:
- DIY, $400 to $1,000: Rent a blower from a home center and add loose-fill cellulose over the existing layer.
- Handyman, $400 to $1,200: Fill bare spots and add batts where insulation is missing.
- Pro (usually best), $1,500 to $4,000: Insulation contractor air-seals and blows in insulation to the recommended depth.
