I just had granite installed and a 5/8 plywood was used.Too much plywood is exposed on the ends. As you look at it from left to right underneath the countertop ,the plywood is noticeable as it goes from maybe a 1/4 to 1/8 then smaller as you look across ,then flush at far the right.Not sure if its done correctly. Needing a little advice.

And without a picture you will never know or get any real advice. Unless your talking about installing it with an overhang like for a bar type setup, not sure why they even used the plywood.This message has been edited. Last edited by: joecaption,

Apparently there is two ways that granite counters are done. One way is they use granite about 1.25 inches thick at the main body (edges are built up more). And then no plywood is used for support. This seems to be more of an east coast way of doing it.
As a Californian that has worked in several counties and different parts, I have never seen that way done here. All the granite places I've worked with or even talked to use a 3/4 granite (with edges built up) and have us install a 5/8 plywood on top of the cabinets.
If the tops of the cabinets are wavey, due to unlevel cabinet tops (faulty installation) then the plywood will be wavey also. But the granite will not be. So I can see how you'd get a variance as you look at the plywood.
This type of thing is why I'm so much a perfectionist, and that does drive people crazy sometimes.
Maybe you can color the plywood to blend in with the cabinet, or maybe you cut the plywood back some. Put a level on the countertop, like a two footer. See if its level from front to back. The cabinet install might be the true problem here. In which case, maybe the granite installers used screws from inside the cabinet to help hold the granite up until their adhesive set up properly.
PS I can't recall every job I've done, but I think some granite companies will do their own plywood install. When I do it, I stop the plywood at the face of the cabinet frame. Maybe theirs sticks out farther than it needs to. Maybe you can remove a layer of the exposed plywood -- that is, make the 5 ply into a 4 ply to help get rid of what shows.This message has been edited. Last edited by: Re-mdlr,
