Inspector's check · Attic
Are gaps around pipes, wires and the hatch sealed?
Look at the attic floor where plumbing vents, wires, recessed lights and chimneys come through, and around the hatch. Dirty or dark insulation is a sign warm air is leaking up through a gap (an attic bypass).
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
Warm, moist air rising into the attic wastes heat, causes ice dams and can grow mold on the roof deck.
If it's a problem
An inspector would write it up as “Air leaks (attic bypasses) into the attic” and rate it routine maintenance. Your options, with rough U.S. costs:
- DIY (usually best), $40 to $120: Seal small gaps with fire-rated foam or caulk and weatherstrip the hatch.
- Handyman, $300 to $800: Seal the bypasses and add a foam cover over the hatch.
- Pro, $800 to $2,500: Energy auditor does a blower-door test and air-seals the attic.
