The answer to 'my stone walkway looks bad' is that there are several common causes, including weeds growing between the stones, cracks or damage to the stones, and dirt/debris buildup. Symptoms may include an uneven, unkempt appearance, tripping hazards, and water pooling. Solutions can range from simple DIY maintenance to more extensive professional repairs, depending on the severity of the issue.
For minor problems like weeds or dirt buildup, homeowners can often handle the work themselves by weeding, sweeping, and power washing the walkway. However, for more significant damage like cracked or uneven stones, it's best to call in a professional landscaper or masonry contractor to properly assess the problem and make necessary repairs.
