I typically do lawn care and landscaping. I recently picked up a few commercial properties and they asked me if I could pressure wash the entry to the store front and remove the old gum, etc. I will have to rent the pressure washer, but at the same time, wouldn't have a problem buying my own set up to add the service. If the area to wash is 15 feet by 100 feet, can anyone provide me what the going rate might be to clean this? How much per square foot can a person get for this kind of service? If you are comfortable providing this type of info and don't want the world to view it, feel free to send me a PM and Id really appreciate the help. In case your worried about me being competition, im in texas....LOL...so if your in another state, Id say its pretty safe to say im not going to be a competitor. Thanks in advance!
