Another factor to consider is the height and features of your home. An example would be a house completely trimmed in Cement Fiber, which does chalk if you do not purchase the correct paint and apply enough of it. Some houses in Coastal Areas are already on 15+ft Stilts (off ground) and then another 20ft high at times. This requires rental equipment and careful cost estimation based on the difficulty of the overall project, The best advice that I can give is to get several estimates in your area and make a decision a couple of weeks afterwards. You will "weed out" per se the individuals that do not have the patience to finish a project that was started-as well as those who haggle you for payment (sometimes daily) before project is completed. I have heard some wild stories from a lot of Homeowners. Common sense and your intuition will make you aware of anyone that you should not hire.
My husband has been a professional painter over 30 years. He prides himself in his high level of work ethic and customer satisfaction. He stays up to date on techniques and finishes. He gives Very detail and accurate appraisals with contracts. At an alarming rate, as he starts to finish the last day or the day before, the client starts nit picking and being disrespectful towards his work when every day prior to that, they were very pleased, as he request ongoing satisfaction throughout the job. Then they don't to want pay remaining balance, bicker about final cost, or stop payment. He has a crew he has to pay whether the customer does or doesn't honor the contract as well as our own household expenses. Wasted time ,labor, money and effort lost. Now how do we fix this? Remind yourself and clients that a contract is based on honor.
