Insulation & Weatherproofing
One room is noticeably colder/hotter than the rest of the house
Likely cause, what to safely try first, and whether it gets worse if you wait.
Likely cause
Insufficient insulation or an air leak specific to that room/wall.
What to try first
- Check for drafts around windows, outlets, and baseboards in that room specifically.
- Note if the issue is worse on windy days — that points to air leaks, not just insulation levels.
