I wanted to have someone who knew how to clean wood siding come out and give me an estimate of what it would cost to do it, and how long it would take them. I found three different companies on the internet that had really informative websites and requested through their sites, to have them come out and give me a bid on the work. Only two of them contacted me within twenty four hours to set up an appointment, and the third did not call back for a week. Needless to say, I had already hired one of the other two prior to the third one calling me.
Out of the two different house washing companies that did give me an estimate, I decided to go with the one that seemed to know what they were doing and explained it so that I could understand the whole process. The second company talked about how to clean wood siding, like he was a genius. He used so many big words, that it made him almost sound stupid. Using the actual scientific names of the chemicals that you use, does not make you sound smart. I thanked him for his time and told him that if I was to go with his company, I would contact them and let them know. I am sure that they have figured out they did not get the job.
