I have a small red omni-stone brick patio in front of my garage...
I've noticed that it is starting to sink and that grass is starting to grow between the bricks...
Is there a sealer I can apply to stop this?
Also, should I remove the bricks that are sinking and level them out before I apply it?
There seems to be no sealer on there now??
Can someone clue me in on the procedure....
Many thanks!

1) What material has been swept into the joints of the pavers?
2) What type of base material is under the pavers?
3) Who did the original installation of the pavers?
4) Do the pavers slope, or have any pitch away from the garage allowing for water run-off?
Just from what you've written, it doesn't sound like the base was compacted properly. Or, there wasn't enough sand swept into the joints. Most professional installers will sweep sand into the joints, as well as plenty of extra sand to as "lubrication" for their plate compactors to make a final pass over the completed project.
If some pavers are settling... it's most likely due to excessive water... either falling on the patio... or running underneath, and washing out the base material.
Unless applied by an installer, or previous owner, pavers will not have a sealer on them. The sealer will intensify the color of the unit, and help protect it from basic stains. IT WILL NOT KEEP OIL FROM STAINING THE PAVERS. A protective sealer is just like "scotch guard" for clothes... it helps give you a few minutes of protection while you make arrangements to clean up the mess.
Finally, weeds in paver joints rarely come from the bottom up... but are from the top down. Meaning the birds, wind and shoes bring more seeds to the patio than can grow from underneath. Why not get everything recompacted... leveled and sloped... and then come back with a polymeric sand... http://paveprod.com/sandstab.html ... and you see an improvement over what you've got now.
Good luck!!!
