Who made the decision to install counters before the windows were installed?

We had to wait 5 months for windows to come in. The countertop is one piece going from inside to the outdoor patio, how else would the window go in anyway?

Are you saying it is one slab and you just installed the window over it? That doesn't seem like a great idea.

I would have preferred to have the window installed first and made sure it was self contained and weather proof. Then you would install the counters as two separate pieces. No one would know that it was or wasn't one slab. Your quartzite is probably porous so you might have moisture wicking from the outside to the inside through the porous slab that you placed under your window.

You wouldn't have stained counters if the window had gone in first.

Did you test your quartzite? A lot of these "white" quartzites are mislabeled and have many marble properties.

I'm not pro, just a homeowners who spent 10 years remodeling a house and the last 3 years designing and building a house and acting as my own designer.

It might just dry out. If it's sealed and you can remove the sealer, it might help it dry faster. Stop getting it wet. :P

Do you have any leftover stone you can play with?

And find out what adhesive was used. I'm pretty sure baking soda and peroxide aren't gonna do anything but make it wetter.

(Your pass-thru counter is awesome!)

Thanks, window company has admitted responsibility but hopefully it dries.
