Painting company website in our point of view ought to have a good design, modern elements, and quality photos. Portfolio page matters much again, this is where a master can showcase the previous works and designs.
We advise creating a separate page for describing materials for work. Often painters work with designers and clients, who are not familiar with the materials and stuff but want to know what exactly occurs. This section can be called a "knowledge base" for interested customers.
Write caching and natural texts, using client-oriented language, adapted for non-professional readers.
Weblium website builder has an intuitive editor, along with user-oriented manuals for those who like to have an instruction.
