Fixing a gap between countertops and sinks depends on the cause of the gap and the type of sink installation. Here are some steps you can take to address the issue:
Check for Proper Installation: If you've recently noticed a gap, ensure that the sink was installed correctly in the first place. Sometimes, gaps can occur if the sink was not properly secured during installation.
Re-Caulking: One common reason for gaps is worn-out or damaged caulking. If the sink is under-mounted or drop-in style, carefully remove the old caulk using a utility knife or caulk remover tool. Clean the area thoroughly, removing any debris and residue. Then, apply new silicone caulk around the perimeter of the sink where it meets the countertop. Smooth the caulk with a caulk smoothing tool or your finger to create a neat finish. Allow the caulk to dry as per the manufacturer's instructions.
Filler Strips: If the gap is larger than what caulk can fix, you may need to use filler strips. These are wooden or plastic strips designed to fill the space between the sink and the countertop. Measure the size of the gap and cut the filler strip accordingly. Then, insert the strip into the gap and secure it in place using an appropriate adhesive.
Sink Clips: For under-mounted sinks, the gap could be due to insufficient support. In this case, you can use sink clips to tighten and secure the sink to the underside of the countertop. Follow the manufacturer's instructions for installing the sink clips properly.
Adjusting Sink Mounts: If the sink is top-mounted or drop-in style and has come loose, you may need to adjust the sink mounts or clips. Tighten them to ensure the sink is securely held in place.
Professional Help: If the gap persists despite your efforts or if the sink installation appears to be faulty, it's best to seek assistance from a professional plumber or installer. They can inspect the situation and provide the appropriate solution.
Remember to take safety precautions and use appropriate tools when working on your sink and countertop. If you're unsure about any step of the process, it's better to consult a professional to avoid causing further damage or injury.
