Some tree trimming companies have been around for years. Others, not so much.

"They've got to be very careful when they just trim a tree," said Scottsdale homeowner Richard Bicicchi. "You don't want branches to fall someplace they are not supposed to."

Another round of storms is expected to rock the Phoenix area this week, which means another wave of trees could topple over.

The Tree Guy Kevin Noonan said there are some questionable companies out there looking to take advantage of customers during the monsoon.

Noonan suggests you do some homework ahead of time to find a reputable tree service before you need it.

"My business is a lot of word of mouth now," Noonan said. "You've got to know what you are doing."

According to Noonan, one of the best things consumers can do is get a referral from a friend or neighbor. Also, look up a company's Better Business Bureau reviews and ratings online.
