I have a fence that I share with my neighbors and I have a couple of questions related to how to properly clean and stain this fence. You can see it in the picture below. There is another segment perpendicular on what you see there and to make the things more complicated that side is shared on a small segment with one neighbor and the rest of it with another neighbor.
These being said here are my questions:
What is the best way to clean and stain this fence considering that the color and the ages of various segments are different. To be clearer, in the picture you have the only two colors and ages present in my fence.
This is more of a legal, procedural question: how do I do the above without having problems with my neighbors. I think that the fence is on the property line so the ownership is shared. The newer looking segment separates me from my left side neighbor while the worse looking segment separates me from the two back side neighbors (back to back properties). One of the back neighbors has a vegetable garden there and I do not want to pollute his garden but I still want to stain/clean my fence. I am planning to use a power washer and an air pressure gun for staining but I am afraid that these might get beyond the fence and that might be trouble. Are there any ways to prevent this ?
