I had this same problem. If you use your patio a lot, it may be to your advantage to have this done professionally. I never use my patio so if I had spent any money on it, I wouldn't be happy. I'm extraordinarily cheap, so fixed it myself. I killed my back in the process (just for a few hours). Depends on a few things - are you on a budget?, are you in good health (if you do it yourself)?, etc. When I need this sort of help (plumber, etc) I always ask my trusted neighbor for advice on doing it myself and if she knows someone who can do it for me. You can get some estimates. The secret to putting pavers down properly is all in the proper foundation of it. (I looked it up on youtube) I would recommend you do the same, just so you know what's involved and if you have someone do it for you, you can see if they're doing it correctly. I would look at at least a few different videos. Everyone seems to have a slightly different way of doing the same thing. You may want to also go to/call your local hardware store and ask them for advice on how to do it yourself. Information is free! If you go there, you may want to bring pictures of the problem. If you want to call, have pics ready on your phone and see if you can email it to them (if needed for clarification).

Thanks Elaine. I appreciate it. I can do it myself but I am not sure how to take care of lights and sprinklers. We try to spend as much time as we can. Since I spent so much money on putting in the patio I don’t want to spend more to get rid off it. Especially with such a nice lighting. I just don’t like the ants on it. I wish I would have never got them done. May be with not too many people working, I might get better deal. Thanks again.

If it is not mortared into place, removal is easy. Replacement is another kettle of fish.

Once it's removed, what are your plans for the area?

I will either add gravel or fake grass. Definitely not real grass. Easy to maintain stuff

If I can remember they are interlocking pavers.

@yardvaark I agree I can treat the area with ants but I have some sunken pavers too and I can see that the seal is also gone. I will take some pictures tomorrow and post. You are correct if I explore the option to make it better I will like it more
