Always have someone from the cleaning service come out and talk to you about the job you want done. You should talk in-depth about the work that needs to be done. After this, the cleaning service will be able to quote you an estimated price for your power washing job. This estimate is very important because the prices charged for power washing services can be highly variable.

Find out if there are any reviews online for the cleaning service. These reviews will give you an in-depth look at the professionalism and skill of the cleaning service. Previous customers of companies like this are often very candid in these reviews. This means that online reviews or local references will give you the best insight when it comes to the quality of a cleaning service.

Make sure that the cleaning service is using relatively new, well-maintained equipment. Older power washing equipment can be very unreliable and even dangerous if it is not properly maintained. Contractors using "hand-me-down" equipment or very old equipment may take longer to finish the job. This means you have to wait longer to get things finished and you may end up getting stuck with a higher bill. After all, repairs add time to the project. As project time goes up, so too does the cost.
