We ordered a window to this company LLC.Sirius the installers came to us, not only were they late, but the old people also had to unload the windows themselves.after they installed the window, they crossed to the window sill, they simply cut it off and put it without strengthening it in any way. grandfather made a remark that the window sill should be cut according to the old pattern, to which they replied that they did not do this.therefore, huge holes were left on the sides of the window sill, instead of being carefully cut and made to whip on the wall like everyone else, the spacer was not put under the window sill at all, they said they did not know where to attach it, and left two rusty corners.in short, you can not approach the windowsill or it will fall. I don't want to place an order in such a company anymore.
