If you want this removed ask a technician about this specialty service as it requires much more work & time than our normal house wash process. This is NOT included in our general house wash!!
Ways to tell if you have oxidation:
A gradual fade under the eaves is a dead giveaway. Almost normal color near the top where it’s in the shade most of the time and considerably more oxidized down lower where it gets sun all day.
Also if you have plants that have been sitting in front of your home & you move them the outline looks new is how much your home has oxidized.
Another way is if you have brushed against your home while being outside & got a white powdery on yourself this is oxidation on your vinyl.
Our company uses low pressure that way it doesn't as badly disturb the natural oxidation process. Pressure washing with high pressure will greatly disturb that process.
