SDPR and Maintainz Property Maintenance are teaming up to conduct search and rescue efforts in Burnsville, NC this Saturday. Residents are currently stranded and in need of 4x4 vehicle assistance to evacuate. We will transport vital supplies directly to those affected.
We invite donations of essential items, including water, fuel, and food, to be dropped off at our shop. We will head out around 3 pm Saturday and stay as long as necessary to support those stranded. Please contact us via private message or phone the shop to support this effort.
