At least two Blooming Grove teen-agers broke into and ransacked two unfinished homes
 Wednesday night, causing more than $5,000 in damage, town police said yesterday.
   After entering the new colonial-style houses on Woodcock Mountain Road, police said,
 the suspects smashed windows, broke doors and kicked in wallboard.
   At 11:30 p.m., police said, they got a call from a witness. Officers responded
and caught a 19-year-old  as he tried to flee.  Washingtonville police also responded.
   A 17-year-old, who investigators said was involved with the mischief, was arrested
 yesterday and accused of assaulting his mother,  police said.
   Both suspects were charged with second-degree burglary
and criminal mischief, both felonies.
   They were sent to Orange County Jail, where they were being held pending a court appearance.
