The answer to 'paver turning brown' is that pavers can turn brown or discolored for a few common reasons. This is typically caused by environmental factors like mineral buildup, mold/mildew growth, or staining from nearby plants or landscaping materials. In some cases, the paver material itself may be wearing down over time, causing a faded or discolored appearance.
If the browning is mild, you may be able to clean the pavers yourself using a paver cleaner or pressure washer. But for more significant discoloration or staining, you'll likely need to have the pavers professionally cleaned and sealed to restore their original color and finish. Sealing the pavers can also help protect them from future staining and discoloration.
