"Combining" Objects to use same texture face

[Rdy2Go]

I'm sorry if this has been asked before, I looked around and couldn't find anything on it.

I am running in to a fairly basic problem and I can't seem to find the solution.

I am trying to build a wall, this wall has a door and so I need to do it in three pieces. Left of the door, above the door, right of the door.

The problem I am facing is that when I select the white wall texture (Meadowbrook white wall) for each there is a noticeable seam, I think it is created by lighting but I am not sure. Any input here would be appreciated, thanks.

Select the 3 faces.
Set Mapping from Default to Planar.Check "Align planar faces".
Adjust the Horizontal and Vertical Scale.
