avoid seams from mask on a texture?

[Alexandros Demetriades 1]

Hi guys need some help!

I'm trying to align the bricks in a texture horizontally...so I draw a line mask and then use the transform to shift the bricks left or right to align them one below the other. (image on the left is the original)...the problem are the visible seams at the edges of the mask...whats the best way to not have any seams? Any help appreciated

No worries I inserted a levels node but after gradient map and adjusted it and it works...!
