If your kitchen sink is not flush with your countertop, one of the first things you can try is adjusting the sink clips. These clips hold the sink in place and can often become loose over time. To adjust them, locate the clips underneath the sink and use a screwdriver to tighten them. This should help pull the sink closer to the countertop and create a more flush appearance.Adjusting the Sink Clips
If your sink clips are damaged or missing, you may need to replace them. You can purchase replacement clips at a hardware store or online. To replace them, remove the old clips and install the new ones in the same location. Make sure to tighten them securely to ensure the sink is held in place properly.Replacing the Sink Clips
In some cases, a silicone sealant can help create a flush seal between the sink and the countertop. This is especially useful if there are small gaps between the sink and the counter. Apply a small amount of silicone around the edges of the sink and use a caulking tool to smooth it out. This will not only help create a more flush appearance, but it will also help prevent water from seeping into the gaps.Using a Silicone Sealant
If your countertop is not level, it can cause your sink to not be flush. Use a level to determine any uneven areas and then adjust the countertop accordingly. This may involve adding shims or sanding down certain areas. Once the countertop is level, the sink should sit flush on top.Leveling the Countertop
If your sink is not flush due to an uneven countertop or an uneven sink cutout, you can use shims to level it out. Shims are small wedges that can be placed underneath the sink to even it out. You can purchase shims at a hardware store or make your own using thin pieces of wood. Place the shims in the areas where the sink is not flush and then tighten the sink clips to hold them in place.Shimming the Sink
Sometimes, the issue of a sink not being flush can be solved by simply tightening the mounting hardware. Over time, the hardware can become loose and cause the sink to shift out of place. Use a screwdriver to tighten any loose screws or bolts and this should help pull the sink closer to the countertop.Tightening the Sink Mounting Hardware

If your sink is not held in place securely, it can cause it to shift and not sit flush with the countertop. Installing a sink bracket can help prevent this issue.
