EPA's Lead Renovation, Repair and Painting Rule (RRP Rule) requires that firms performing renovation, repair, and painting projects that disturb lead-based paint in homes, child care facilities and pre-schools built before 1978 have their firm certified by EPA (or an EPA authorized state), use certified renovators who are trained by EPA-approved training providers and follow lead-safe work practices.
Your painting contractor should be able to tell you which premium products they use, and why. High-end materials and products perform better, look nicer, and last longer - if your contractor uses low-end options to drive your cost down, they’re not doing you any favors. When reviewing your proposal make sure a specific product is listed, not just a paint manufacturer. Every manufacturer has contractor grade options.
Stucco is a specialized material that requires extensive preparation work (cleaning, caulking, filling in cracks, etc.). Additionally, paint suitable for rolling or brushing over stucco varies greatly depending on location and climate conditions. Some stucco paint varieties will chip and peel away in certain climate conditions, so painting professionals won't recommend them. These factors make stucco one of the more expensive siding materials to cover. You can expect to pay anywhere from $900 (~500 sq. ft.) to $3,000 (~1,500 sq. ft.) to have stucco revitalized with paint, depending on how much is needed to cover the home exterior.
