We compute  the distribution of the conductance $P(G(T,V))$  of  a one-dimensional disordered wire  non-perfectly coupled to leads (dirty contacts) atfinite temperature $T$ and bias voltage $V$. At regimes of temperatures and/or bias voltages larger than the mean level spacing, we show that the conductance distribution can be accurately represented by a finite number of convolutions of the distribution $p(g_c)$ of the conductance $g_c$  at zero temperature and zero bias voltage.
