Police say the male suspect is refusing orders to surrender and has fired shots at officers.
It is believed that he is inside the home by himself. Hostage negotiators were trying to establish contact with the man.
Delaware State Police say at 8:22 p.m., the Explosives Ordinance Disposal Unit utilized an explosive breaching charge on the front door, however, they have not entered the home, as of yet.
The suspect's name has not been released.

Residents in the area have been evacuated. No injuries have been reported.
The trooper was shot around 12 p.m. Wednesday at the Wawa store on Pulaski Highway (Route 40) near Salem Church Road.
Officials say the trooper spotted a suspicious vehicle occupied by two suspects in the Wawa parking lot.
The trooper made contact, officials say, and then there was a struggle.
That's when one of the two suspects got out of the vehicle and fired several rounds, striking the trooper.
Kevin Lerner says he saw the shooting. He works at the barber shop next to Wawa.
"When he pushed the officer he got a little room to run. So he pushed him and ran, and when he ran he ran for like seven or eight feet. And then he turned around and started shooting," said Lerner. "Just instantly started shooting."

"This is a sad day for our state and our Delaware State Police family. We ask that you keep the trooper's family, and the Delaware State Police family, in your thoughts and prayers," said Delaware State Police Superintendent Nathaniel McQueen.
A caravan of law enforcement vehicles accompanied the slain officer's body to the state Division of Forensic Services for an autopsy, and observers placed their hands over their hearts as it passed by.
