How to Tell If Your Insulation Is Failing You
Insulation doesn’t last forever, and in many San Antonio homes, especially those built decades ago, the insulation that’s in place may be compressed, damaged, contaminated, or simply insufficient by modern standards. The challenge is that insulation is hidden inside walls, attics, and crawl spaces, making problems difficult to spot without knowing what signs home needs new insulation San Antonio homeowners should keep an eye out for.
8 Warning Signs Your Insulation Needs Attention
- Unusually high energy bills that have increased over time without explanation
- Rooms that are difficult to keep cool in summer or warm in winter
- Temperature inconsistencies between rooms or between floors
- Cold walls, floors, or ceilings to the touch (indicating heat transfer through surfaces)
- Drafts felt near walls, outlets, or baseboards
- Pest infestations, rodents, and insects damage insulation and leave behind contamination
- Water damage or flooding history, wet insulation loses effectiveness, and can harbor mold
- Your home was built before 1980, and insulation has never been replaced
The Problem with Old Insulation
Fiberglass and cellulose insulation both degrade over time. Fiberglass batts can compress, shift, or develop gaps as a building settles. Cellulose can compact and settle significantly, reducing its effective R-value. In attics, insulation may also be contaminated by roof leaks, pest activity, or decades of accumulated dust, all of which compromise thermal performance and potentially indoor air quality.
In some older San Antonio homes, asbestos-containing insulation materials may still be present, particularly vermiculite attic insulation or older pipe wrap insulation. Any suspected asbestos-containing material should be tested before removal.
