Avoiding Water Damage During Sink Replacement

Replacing your kitchen sink is a great way to refresh your space—but if done improperly, it can quickly lead to costly water damage. At I Hate My Sink, we’ve seen cases where a simple swap turned into a full-blown renovation due to leaks that were overlooked during installation.

The key to preventing water damage is preparation and precision. Always shut off the water supply before you begin, and have towels and a bucket on hand to catch any leftover water from disconnections. When installing the new sink, take time to apply a watertight seal with quality silicone caulk and ensure all plumbing connections are tight and properly aligned.

Once installed, always run a full water test before finishing the job. Check under the sink for drips or pooling, especially around the drain, faucet lines, and P-trap. Even a slow leak can lead to rot, mold, and damage to cabinets or flooring if left unchecked.

If you’re unsure about any step, it’s worth calling in a professional. A quick install shouldn’t turn into a long-term repair—and a properly installed sink will keep your kitchen dry, clean, and stress-free.
