Sign companies split into disciplines that do not overlap as much as the industry name suggests. A business strong at channel letters and electrical signage is not automatically equipped for a carved monument sign, a wayfinding system, or a fleet of vehicle wraps. We record which sign types a company actually fabricates rather than assuming one company does all of it well.
Electrical signage carries a real safety requirement. A sign plugged into building power should carry UL listing, and a company that fabricates its own electrical signs should be able to say so. We check for that statement because it is the one detail that separates a sign shop from an electrician's liability problem.
Permitting is the part that actually controls the timeline. Most cities require a sign permit before installation, and the application can take longer than building the sign itself. We record whether a company states that it handles permitting or leaves that step to the customer, because that single detail can turn a project from weeks into months.
Turnaround time gets published inconsistently. Some companies state a production window from approved design to install; most do not. Where a company states one, we record it, because a sign shop that will not commit to a timeframe is telling a buyer something too.
