Tennis ball stuck in guttering!?

If the gutter is wide enough, it shouldn't be a problem. The only way it would become a problem is if the ball is large enough to cause a blockage and stop the gutter from draining away water. This can cause it to overflow or in extreme cases, it could get too heavy and drop down which could be costly to repair. Depending on how hard it is to get, i'd recommend trying with a ladder if possible. Just be careful you don't fall down

Hope this helps :)

this is a uk site ..standard guttering is 100mm 4" about the same size as a tennis ball ..im a builder ..yes it will cause a problem ..and you must get it out

use a hose pipe put in bottom of downpipe and push if the hose is heavy duty it will push the ball to the top where a mate at top can retrieve it
