Why do illuminated signs flicker or go dark?
Illuminated signs flicker or go dark most often because of a failing ballast or driver, loose or corroded wiring connections, or individual LED modules reaching the end of their service life. Moisture intrusion into the sign cabinet is another common cause, particularly on older signs with worn seals or cracked faces that let water reach the electrical components. A sign that flickers intermittently rather than staying fully dark usually points to a wiring or connection issue rather than a component that has fully failed, since a complete component failure typically produces a steady dark section instead of flickering. A facilities manager noticing flickering should have a sign technician inspect it promptly, since a wiring problem can worsen into a fire or electrical hazard if left unaddressed.
How much does it cost to repair a commercial sign?
Commercial sign repair costs vary by the type of problem, with a simple bulb, LED module, or ballast replacement typically costing a few hundred dollars including a service call, while a damaged sign face, cabinet, or structural repair after storm damage can run into the thousands depending on size and materials. Signs mounted at height often add cost for lift equipment needed to access the repair safely. A facilities manager should ask a sign service company whether the quoted price includes the service call, parts, and any lift rental separately, since bundling those into one number makes it harder to compare against other bids for the same repair.
Who is responsible for repairing a damaged sign, landlord or tenant?
Responsibility for sign repair typically follows the same line as sign maintenance in the lease, meaning a tenant is usually responsible for their own storefront or building sign while a landlord handles shared structures like a shopping center's monument or pylon sign. Some leases specify that tenants must keep their sign in good repair as a condition of maintaining their storefront's appearance, with the landlord retaining the right to demand repair if a sign is left damaged for an extended period. A facilities coordinator dealing with a damaged sign should check the lease's signage and maintenance clauses directly, since assuming responsibility without confirming it in writing can lead to a dispute over who pays for the repair.
Can storm-damaged signage be repaired or does it need replacement?
Storm-damaged signage can often be repaired when the damage is limited to a cracked face, bent panel, or lighting component, since those parts can typically be replaced without touching the sign's structural frame or foundation. Replacement becomes the more practical option when a storm has bent or compromised the structural post, damaged the foundation, or torn the cabinet apart, since repairing a structurally compromised sign risks the same failure recurring in the next storm. A facilities manager should have a sign technician assess the frame and mounting hardware, not just the visible face damage, before deciding between repair and replacement, and should check whether property insurance covers the damage before committing to either option.
How often should commercial signage be inspected?
Commercial signage should be visually inspected at least twice a year, with an additional check after any significant storm, high wind event, or other weather that could have loosened mounting hardware or damaged the structure. A basic inspection should look for cracked or faded faces, flickering or dark sections, loose panels, rust on the structure, and any leaning or shifting of a monument sign's foundation. Illuminated signs benefit from a nighttime check as part of that inspection, since lighting problems are often invisible during the day. A facilities manager who keeps a simple dated log of sign inspections has a useful record if a dispute arises over how long a hazard existed before it was addressed.
What causes commercial sign faces to fade or discolor?
Commercial sign faces fade or discolor mainly from prolonged ultraviolet exposure, which breaks down the pigments and plastic materials used in most sign faces over years of sun exposure, with south and west-facing signs typically fading faster due to more direct sunlight. Heat cycling, where a sign face repeatedly heats up during the day and cools at night, also stresses the material and speeds up yellowing, particularly in older acrylic faces. Air pollution and grime buildup can compound the appearance of fading even before the material itself has significantly degraded. A facilities manager can extend a sign face's usable life somewhat with periodic cleaning, but eventual UV fading is expected and should be budgeted for as a routine replacement cost over the sign's life.
Is a permit needed to repair or replace a sign face?
A permit is often not required for a simple like-for-like sign face replacement that keeps the same size, location, and message, since many jurisdictions treat that as routine maintenance rather than a new installation. A permit typically becomes necessary when the repair changes the sign's dimensions, alters its structure, adds or changes illumination, or replaces the entire cabinet rather than just the face panel. Rules vary meaningfully between jurisdictions, so a facilities manager should not assume a face swap is automatically permit-free without checking local requirements first. Confirming with the local building department before starting the work is the safer approach, since an unpermitted change that should have been permitted can result in a stop-work order or fine.
