1. Mold and Mildew

Mold and mildew are the most obvious signs of water damage. But do you know what places in your bathroom tend to trap water? Mold loves to hide behind broken tiles, drywall, and painted surfaces. It also grows in old grout and deteriorating caulk.

Do mold and mildew reappear after scrubbing? If so, it’s because the mold and mildew are growing from the inside out. No matter how much you clean, you’re not able to remove mold and mildew at the source.

Gently push on the tiles or drywall. It shouldn’t move underneath. If it does, you have water damage.

If mold continues to return after cleaning, there may be hidden moisture behind walls, under flooring, or around plumbing fixtures. Learn more about removing mold and mildew in your bathroom and when professional remediation may be necessary.

2. Musty Smell

A proper ventilation system can remove moisture from the air after you take a bath or shower. But the musty smell of mold and mildew can still hang in the air.

Your bathroom should never smell damp. If it does, call us for water damage restoration as soon as possible. We also offer certified mold remediation if we find mold in your walls and subfloor.

A persistent musty smell is often one of the earliest signs of hidden water damage. In many cases, mold growth can begin before visible staining or structural damage appears.

Read our guide on common signs of a mold problem if you suspect moisture may be hiding behind walls or under flooring.

3. Dripping Faucets

A dripping faucet may not seem like a big deal at first. But over time, it can lead to water damage in your bathroom. We recommend you call a plumber to inspect the sink or tub. That way, they’ll be able to fix the dripping faucet before it becomes a bigger problem.

4. Slow Drains

Is the water draining slower than usual in your tub or sink? A clogged drain can cause pressure and bacteria to build up inside your pipes. Over time, the blockage may create the ideal environment for mold to grow. Pipes can also burst if water builds up, but has nowhere to go.

Call a plumber as soon as you have problems with a slow drain. It could mean the difference between a small repair and water damage restoration.

Drain backups and plumbing issues are among the most common causes of residential water damage. Addressing slow drains early can help prevent larger restoration projects later.

5. Cracks in Caulk and Grout

Water is opportunistic. It will seep into the smallest of cracks in your caulk or grout. From there, water can drip down inside your walls and into your subfloor.

Make sure you keep your bathroom in good condition, reapplying caulk and grout as needed. Doing this will help reduce the number of places water can get trapped. It’ll also reduce the likelihood of mold, mildew, and wood rot.

6. Spongy, Unstable Floor

Does your toilet seem a little tippy? This can happen when water damage weakens the floor of your bathroom. Many bathrooms have plywood subfloors, which rot when exposed to water. Water-damaged floors will feel soft and spongy when you walk on them.

7. Spongy, Warped Walls

Drywall softens and bubbles when exposed to water. Over time, the amount of water damage will increase and warp your wall. Not only is water damage bad for your bathroom, but it affects the stability of the rest of your house.
