The answer to 'my paver looks bad' is that there are several common causes, including uneven settling, weed growth, and staining. Pavers can become discolored, cracked, or sunken over time due to weather, traffic, and other factors. The specific solution will depend on the underlying issue.
If the pavers have settled unevenly, you may be able to fix this by carefully lifting and re-leveling them. Weeds growing between pavers can also make the area look unkempt, but these can usually be removed by hand or with a weed killer. Staining from spills or environmental factors may require special cleaners or sealants to restore the pavers' appearance.
