Lenny,
Awnings can be very profitable. Awnings are also very easy to ruin. I usually charge anywhere between $1.50-3.50 a linear foot depending on the width.
A few key things to know.
Vinyl awnings are made from petroleum. Many customers have told me they have used a degreaser on the awning to remove stains. Yes that works but it also removes the layers; no different then removing a few layers of skin to get clean while showering, no thanks.
Always do a test spot before cleaning. You should use a Q-Tip dipped in the chemical you are using and apply to an area of the awning not seen by the public. If you get color on your Q-Tip don’t clean; the color is on the surface only.
There are lots more…………………..
May I suggest calling Do-it-Right? They are from Florida. Good company. Reliable products. They don’t just sell you stuff they actually know what they are doing because they operate a profitable awning cleaning and sealing company. If you cannot find their number contact my office and they will find it for you.
Good luck
