Chris Powell admits Charlton's home form is a growing concern after a 1-0 loss to Barnsley made it more misery at the Valley.
Tomasz Cywka's goal means the south Londoners have still not won on home soil since August and Charlton manager Powell says it is an issue that must be addressed following their latest defeat.
"We don't want it to snowball and we need to get ourselves out of," said Powell. "We need to approach each home game with the belief of getting three points. But we are not doing ourselves justice."
He added: "We need to turn it around - even if that means an ugly performance as we want to pick up some points."
The home side were second best throughout and, after they squandered first-half chances, Cywka struck from the angle in the 67th minute to condemn them to defeat.
Charlton's day went from bad to worse when Ricardo Fuller limped off with a hamstring injury, leaving the hosts down to 10 men having used all their substitutes.
A late rally proved fruitless, with substitute Bradley Pritchard coming the closest to an equaliser when he was denied late on by Barnsley goalkeeper Ben Alnwick.
"It was a real frustrating day," added Powell. "We didn't play with enough tempo or consistency. They settled into the game and we didn't do enough to affect it."
Barnsley manager Keith Hill says his side's win was fully warranted.
"The result is key but the performance is a reflection on what we have been doing most of the season," he said. "We controlled everything really. They had a bit of momentum at the end. Having the ball is key and getting it back is key. At the moment we have a front-door key and a back-door key."
