If you’ve driven past the Greencastle McDonald’s on I-81, you’ve seen their massive high-rise sign — standing over 100 feet tall and visible straight from the highway. We recently spent a few full days giving that sign the attention it deserved.
Over time, large signs like these build up a lot of humidity, which can lead to organic growth inside the cabinet. When that happens, the sign can start to look dull, patchy, or uneven at night. Most people never think about that — but a good cleaning can make a world of difference.
For this project, we:
• Thoroughly cleaned the inside and outside using commercial-grade cleaners and power washing
• Added treatments to help prevent the growth from returning
• Replaced many of the internal lamps with brighter, fan-cooled LED bulbs for better lighting and increased airflow
• Upgraded the electrical service, including new grounding, a rebuilt service panel, ground-fault protection, and a surge protective device
• Made sure everything is safely wired, protected, and ready to shine for years to come
You can really see the difference in how clean and bright those golden arches look now!
If your sign lights up at night but has dull or uneven spots, it might just need a deep cleaning. We love going the extra mile to make sure our customers’ signs look their absolute best — day and night!
