Problems: Water damage, higher heating and cooling costs, increased risk of burglary.
Trouble signs: Air drafts; loose or cracked caulk around windows and doors (interior and exterior); water stains near windows and doors; weak security of windows and doors.
What you can do: Remove damaged caulk and reapply silicone caulk around interior and exterior windows and doors. Install plastic insulation sheathing on old windows. Use window locks and install deadbolt locks on doors — one in three home burglaries results from unforced entry.
What it may cost: A $10 insulation kit is good for six windows. Deadbolt locks start at $20 and can be installed by a DIY-er in less than one hour. A locksmith charges $50 or more to install a deadbolt.
What you could save: Thousands in water damage or up to hundreds annually in wasted energy cost; your possessions not being pilfered.
