There are a few very useful tools homeowners should have on hand . . .
Tape Measure: $4
Measuring house projects requires a tape measure, not a ruler or a yardstick. Be sure to get a good quality, easy-lockining 3/4" wide, 16ft. long tape measure
Caulking Gun: $15
Caulking is the process of sealing up cracks and gaps in various structures and certain types of piping. Caulk should be applied only to areas that are clean and dry.
Screwdriver Set: $20
It's best to have four screwdrivers in your set -- a small and large version of the Flat-head and Phillips-head screwdrivers. Electronic screwdrivers are handy, but they're no substitute for the manual screwdrivers which can reach into more places and are less likely to cause damage.
