The answer to 'paver brown patches' is that brown patches on pavers are typically caused by a buildup of dirt, debris, or mold. Symptoms include unsightly discoloration and an uneven appearance in the paving. To solve this issue, the pavers will need to be thoroughly cleaned and treated.
For minor brown patches, homeowners can often address the problem themselves by scrubbing the affected areas with a stiff brush and a paver cleaning solution. However, for more extensive or stubborn staining, it's best to call in a professional landscaper or paver cleaning service. They have the right equipment and expertise to properly restore the pavers without causing damage.
