Please see attached picture it appears that there is no caulking between the countertop & backsplash. I just noticed this area, it is right behind my faucet where water could drip down into the back of cabinet & cause mold & water damage. Also, is this a real Quartz Countertop? The contractor who installed it won't provide any details or paperwork about it.
Yes. This gets clear silicone caulk. If you are arguing with a countertop guy over paperwork good luck. But he should have caulked. But this can be done for $4-5 and 5 mins so it isn't the end of the world.
