Both options have their pros and cons. Spraying is the faster method that usually only requires one coat coverage, is free of brush marks and can get into hard to reach areas. Spraying does, however, have a longer prep time, the possibility of uneven coverage, and poor adhesion. Brushing has excellent control, good adhesion, uniform coverage and is better for getting into smaller cracks. Brushing takes a lot longer, requires two coats and can leave brush marks. Make sure your contractor has solid and definite reasons for picking one method over the other.

The question, “how is your warranty program funded?” will probably get you some puzzled responses.  The fact is, most contractors have never even considered how to pay the expenses associated with warranty callbacks, and some contractors just seem to vanish when they get a warranty call.  A professional contractor will be preparing for callbacks (they will happen, even to the best contractors) by including a line item in their budget for warranty work.  Ask the question and see what kind of response you get.  Sometimes, how the question is answered is more important than the answer itself!
***Payment Policy:  Weiler Painting will receive payment of Cash, Check, or e-Transfer for services rendered.  A deposit is usually required for most jobs to cover the material costs of the project.  For projects in excess of two weeks a interim payment will be required and can be discussed prior to commencement of work.  Payment is to be made in full at completion of work stated in contract.
With that said, here's the reality of that particular scenario. Painters do put water in the paint, but not for reasons you would think. Some materials need to have their viscosity manipulated in order to slow drying time, allowing gravity to 'smooth' out the product for a better finish. It also prevents 'drags' and 'sausages'. I personally try not to do it too often, but from time to time I have to. I want my client to have a proper finish.
Some contractors work on time and material others on a firm contract. I would never hire the former and am leary of the latter. A contractor may low-ball a bid to get the job planning to make a killing on change orders. If you say good morning to them, they charge you extra for that. If the contract is not very, very specific and extensively fleshed out or if they display their change order schedule prominently on top, show them the door.
