Why choose us

Newer signs are constructed to be more durable and to hold up longer with less maintenance. However, older signs can need a more frequent upkeep to ensure they are still valuable advertisement investments. You might even need to think about an upgrade. For example, older neon signs break so often most company owners choose to replace the lighting with light emitting diodes which require little maintenance for a longer lasting marketing tool. All signs have a lifespan, but your sign’s longevity can be greatly expanded by maintaining and repairing your signs!

Signage Cleaning and Maintenance

The location of your sign may affect its maintenance schedule. In larger cities and industrial areas, it may be necessary to clean signage more often, as corrosive particles run rampant, and pollutants can adversely affect paint and other surfaces. Coastal areas have higher salt concentrations, which may negatively affect the color of your sign. Tree resins, animal droppings, and pollen should be removed as soon as possible to avoid general scratches and corrosion. Paint and plastics are susceptible to sun damage, and colors will fade over time from everyday exposure. A wax-based car detergent, acting as a shield against pollution and UV radiation, can help extend the life of your sign.

8 Steps of Sign Cleaning Maintenance

  1. Secure the job site for safety. By roping off the designated area, we keep pedestrians out of danger & the necessary space available to work safely.
  2. Remove all necessary components. Hardware, brackets, exterior frames, panels & old lighting. By removing all these parts, we are able to access even the most hard-to-reach areas and do the most thorough clean possible.
  3. Inspect and repair as necessary any faulty electrical components. To prevent any hazards to the sign, we make sure everything is in great working conditions, such as the wiring, sockets, ballasts, transformers, etc… which can often deteriorate from the elements over time.
  4. Scrub, scrub, scrub! We take time to thoroughly clean the interior and exterior of the sign, including of course, the main face of the sign & the frame to keep your image looking superior! As a first impression of your business, the appearance of your sign is extremely important.
  5. Install new lighting! To get the best overall appearance, it is important to have uniform illumination. For this reason, as well as to reduce your cost of frequent service calls, we replace all the bulbs at the same time.
  6. Replace the shiny clean sign face, frame, hardware & brackets. We make sure everything is nice and secure, and fitting properly. Frequently we see, loose bolts, or bent and damaged frames, as a result of severe weather damage. We want to make sure everything is in tip-top shape for you!
  7. Clean up time! We are sure to clean up after ourselves, and leave the site in the condition it was found. We don’t want to leave behind any debris, or mess that may have occurred in the sign-cleaning process. It should look like we were never there (besides the sparkly clean, new-looking sign you now have)!
  8. Written recommendations as necessary. If during the cleaning process we find something to bring to your attention regarding your sign, or possible advice on how to extend the life of your sign or reduce maintenance costs, we will contact you with this important advice.

  • Dust and clean seasonally – a deep cleaning to remove any dirt and residue is vital to keeping your sign healthy. This should be done 4 times per year, at minimum.
  • Remove paper inserts and ensure the cleaning cloth is damp, but not soaking wet. This will keep interchangeable name dry and prevent deterioration.
  • Use a clean, non-abrasive cotton cloth or air duster to remove dust from crevices, particularly if the sign has dimensional letters (wall signs, reception signs).
  • Use mild soap mixture (detergents such as Dawn or Palmolive are recommended) diluted with lukewarm water to wipe down any residue build-up.
  • Work in small areas, one section at a time.
  • Blot detergent away with a soft fabric.
  • Keep signs dry and clean more often if your office is in a humid area.

  • Wash seasonally.
  • Use clean water and car shampoo, as this type of detergent contains a protective wax. (Protective wax should only be used on specific materials. Please see one of our sign experts if you’re not sure whether or not your exterior sign falls into this category.)
  • Remove excess parts, such as hardware, frames, and panels, to get the deepest clean.
  • Thoroughly read detergent ingredients to avoid damage to the substrate.
  • Take extra caution with the edges of dimensional letters and other raised surfaces.



  • Use abrasive cloths, sponges, scrubbing brushes or detergents.
  • Use cleaning cloths that have been used for other surfaces, as this could cause unintended chemical reactions.
  • Pressure wash or steam clean signs.
