Fixing Uneven Attic Insulation Coverage

Uneven insulation contractor in the attic can cause drafts, uneven temperatures, high energy bills and even ice dams in winter. Irregular framing, tight corners, and existing structures like pipes or wiring present obstacles in attic spaces, making it hard to achieve an optimal R-value (the higher the R-value, the more effective the insulation). A good way to test how much of your attic is insulated is to measure the space from the floor to where the ceiling meets the joists. This will give you an idea of how much of your attic is insulated, and if the insulation needs to be replaced or added.

An attic inspection can also identify cold spots and gaps around vents, chimneys, and plumbing penetrations. Look for signs of moisture, such as dark stains or odors. If you have a finished room built into your attic, open cavities in the floor framing near ducts and kneewalls can leak air. These spaces can be plugged by sealing with expanding foam or caulking.

Fixing Uneven Attic Insulation Coverage: A Homeowner’s Guide

Before starting to add insulation, make sure that the attic space is clean and dry. It is also a good idea to gather all your tools in one place and to start the project early, as attics heat up throughout the day. Wear a dust mask and safety glasses, and remember to wear gloves when handling insulation. Avoid touching vermiculite, which may contain asbestos; if you think your attic has this material, have it tested by an approved lab.
