If you have had a paver patio or walkway installed 9 times out 0f 10 it never got sealed. This is because you cannot immediately seal the pavers as it might lock dampness under the sealer this is why most of the time you will need to hire a 2nd team to come and do the sealing of your pavers.
The steps we take when we come to seal your paver patio or walk is 1st clean off all pavers and if there is stains remove any stains. Next we apply the sealant and sweep it on your pavers evenly giving a nice bright shine.
As you can see there is a big difference before and after sealing pavers.
