The Elbert Street house sustained some smoke damage after firefighters pulled down the wall and ceiling of an adjoining bathroom to be sure the flames hadn't spread.
No one was hurt in the 5:30 a.m. two-alarm blaze, which responders said was doused in a half hour or so.
The cause hadn't officially been declared.
Allendale and Mahwah firefighters joined their Ramsey colleagues, who included Ramsey Rescue. Borough police and EMS also responded.
It was the second working fire in a little over a week in Ramsey that crews handled with “textbook tactics” to spare homes and other property, the department said.
They quickly doused a basement blaze on Grove Street on April 8.
