Problems with unwrapping a building.

I’m having trouble unwrapping my building model. Its a a pretty basic model with extrusions for a window and a balcony. I’ve put seams to seperate each side of the building and certain parts and unwrapped it only to get a bunch of stretch because the unwraps aren’t in proportions. What other method of unwrapping would you suggest? If you need a pic of what I’m dealing with feel free to reply. Thanks
