Most signage projects fail in the same two places: an artwork problem discovered after manufacture, and a consent requirement discovered after that. Both are avoidable, and both are why we survey before quoting rather than pricing from a photograph and hoping.
A straightforward fascia runs four to six weeks from survey to installation. Where advertisement consent is needed, add around eight weeks, though we run the application and the manufacture in parallel rather than in sequence so consent is not the only thing on the critical path.
