Police agencies across the state are warning home and property owners to watch out for potential scammers as the weather warms up. Officials say this is the time of year when residents are approached unsolicited with offers to pave and seal driveways, or perform home repairs. The scammers are often seeking access to the homes to commit theft or demand payment up-front and either perform substandard work or none at all. Residents are urged to never allow anyone into their homes and call the police if they are suspicious.
