Ask for a Demonstration. This is not always required, but if you are not sure about job outcome or expectations, a demonstration of a service may settle your mind. Make a demonstration mandatory if you cannot be present at job start-up or if the service has few job satisfaction policies.
As a note, demonstrations take an enormous amount of time from the contractor. Often they will try to forgo demonstrations, asking the client to be on-site during the estimate and/or job start up in order for you to evaluate work performance. This is not uncommon.
Quality pressure washing contractors are in high demand and are very busy. They are just trying to make the whole process more time-efficient. If you are dissatisfied, don’t hesitate in telling them so. In the long run you will have saved them both time and effort.
Inquire about Equipment. Is it owned or rented? Owned or leased equipment is evidence of a long term commitment to the field of pressure washing. Renting shows only an occasional need for equipment. Also ask about the extent or power of their equipment.
For most pressure washing jobs they will have equipment ranging at 11-15 HP (horsepower, strength), 3000-4000 PSI (pound per square inch, force) and 3-5 GPM (gallons per minute, flow). While for the most, they will not be using their equipment at full power, equipment of this caliber provides the head room and adequacy for doing business.
A rating of 2000 PSI and 2 GPM or less, is a residential grade of equipment. It will not perform at the level of doing business (possible evidence of a substandard service provider).
Get Referrals. These provide the consumer with a detailed track record of contractors past work experience. Just remember, a pressure washing business is called to perform any number of different cleaning services.
Whether it is siding, decks, sidewalks, gutters, patios, or driveways, be sure the referrals and references you receive are representative of the service you desire. For instance, someone seeking deck cleaning should receive deck cleaning referrals, not vinyl siding cleaning.
As for a number of referrals, the more the better, but 6-12 should suffice. And don’t forget, once you have the referrals, use them. Ask specific questions concerning quality, workmanship, expected outcomes, cleaning procedures, business character, and satisfaction.
Satisfaction and Billing Policies. A number of power washing businesses offer various policies that help ensure customer satisfaction. One of which, is the suspension of billing until job completion and customer satisfaction. Ask the contractor, in the event of customer dissatisfaction, what their policy is.
Insurance. Check to see if your contractor carries liability insurance. A qualified pressure washing contractor, realizing their responsibility, will have taken the time to protect both themselves and their clients from possible on-site accidents, injury, or damage.
Be Present at Job Duration and Completion. This is your way of observing work activity as it takes place. It gives you an idea of what is involved in pressure washing and allows seeing cleaning results as they occur.
Quite often, the results in cleaning are remarkable and the consumer should experience this process first hand. You actually see the effectiveness and value of the service for which you will be paying. It settles the mind, knowing you have received good service for your hard earned dollar.
Being present also allows you to head off any problems and catch any areas that may be missed or improved upon. A contractor is much happier to improve such areas (ensuring satisfaction) during the job, than to return later in the future, since returning will consumes enormous time and effort for which the contractor is probably not getting paid. Again another benefit for both parties.
