The answer to 'patio installation turning brown' is that a patio turning brown is often caused by moisture, mold, or mineral stains. This can happen when the patio material absorbs water and develops discoloration over time. Symptoms include a dull, brownish appearance and potential cracking or crumbling of the patio surface.
Some common causes are improper drainage, poor sealant application, or natural weathering and aging of the patio materials. To fix a brown patio, you may need to clean, reseal, or in some cases replace the damaged areas. DIY solutions like pressure washing and applying a new sealant can work for minor issues, but more extensive damage may require hiring a professional landscaping or patio contractor.
