Came home to find my undermount sink in kitchen fell. Suggestions on how to lift and hold in place.

Double sink and granite counter top if that makes a differnce.

Never Fall Complete Sink Repair

It’s legit and easy to install.

Clean the silicone from the the top of the sink. Apply new silicone and lift sink and secure by sliding a 1x2 in the from and back and pocket screw into the sidewalls of the cabinet on both sides.

Need two lengths of 2x4, two pieces of long enough 3/8" all-thread, large washers, and nuts. Basically you just need run the all-thread through the drain openings and into the 2x4's to create a clamp. This works far better than using beam or pipe clamps, also forget using silicone to adhere the sink to the granite, it will fail again, you need to use construction adhesive like PL Premium or two-part gun-grade epoxy. I also use epoxy mounted studs to reinforce after the initial work as set. Go back with silicone to fill the inside seam but never use it as a primary adhesive for an undermount of any type. I do this repair several times a year, not difficult but also not one you want to do every few years either.

Thanks for the suggestions.

I had originally thought of the bottle jack as I have used that method in the past to hang cabinets.

After reading through the different suggestions, I went with Clames' method of using threaded rods and 2x4s. This worked like a champ

I also used construction adhesive as was suggested as opposed to silicone for the attachment.

I also took tigerfan311's advice and ordered the Never Fall Complete Sink Repair. It arrives tomorrow and that should give the construction adhesive a little of 24 hours to cure.

Between the two suggestions used/to be used, this sink should no longer fall again.

I wanted to use awestruck's suggestion but she was not available.
