Due to heavy sun exposure and seasonal rain in the Charlotte area, most pavers should be sealed every 3–5 years. Pool decks and high-traffic areas in places like South Charlotte, Ballantyne, and Fort Mill may require more frequent sealing.

Unsealed pavers in North Carolina are prone to fading, algae growth, and joint sand erosion due to humidity and rain. Over time, this can lead to loose or uneven pavers that require costly repairs.
